Description

  The present invention relates to an elastic warp knitted fabric knitted by using inelastic yarn and elastic yarn together, a bonded fabric obtained by using the knitted fabric, and a garment thereof.

  2. Description of the Related Art Conventionally, for example, an edge such as a skirt portion of clothing has been cut off in a state where it is cut, so it has been necessary to perform some sort of trimming in order to prevent the edge from being cut off. The method of trimming the edge varies depending on the site and the material of the garment. For example, the edge of the fabric is folded back and sewn twice, or another fabric or a tape is attached to the edge of the fabric in a substantially U-shaped cross section. There is a method of covering and suturing. However, this trimming puts a heavy burden on the sewing work of clothes. In addition, the garment that has been trimmed has a thicker portion, and when wearing a tight outer garment on such garment, the rim line of the garment appears in the outer garment as a ridge and impairs the appearance. However, there has been a problem that the thickened edge portion impairs the feeling of wearing.

In order to solve such a problem, there has been conventionally known a method in which one vertically continuous piece is used for clothing, and an edge portion that does not need to be trimmed is formed by thread removal (Patent Document 1 below). 2 and paragraphs [0019] and [0020] of Patent Document 2. See FIG. 3 and paragraph [0014] of Patent Document 2. See FIG. 1 and paragraph [0020] of Patent Document 3. However, in the case of an edge that is not required to be trimmed by thread removal, the edge shape must be straight, and when the upper and lower edges are formed by thread removal, the upper and lower edge lines are not used. Had to be parallel pieces. In addition, when a piece whose upper and lower edges are not parallel to each other is used for clothing, there is a restriction that at least one edge has to be trimmed.

  The stretchable warp knitted fabric of the present invention has the advantage that the edges are less frayed and the cutting flexibility is high. Further, the bonded fabric of the present invention has the advantage that the edges are less frayed and the degree of freedom in cutting is higher. Since the garment of the present invention uses such a stretchable warp knitted fabric or a bonded fabric, the edge of the garment does not need to be trimmed, and the rim line of the garment appears on the outer garment and impairs the appearance. There is an advantage that the wearing feeling is not impaired.

  The stretchable warp knitted fabric of the present invention is preferably finished to a density exceeding 55 wale per 2.54 cm (1 inch). This is because the stretchable knitted fabric is stabilized.

  In the stretchable warp knitted fabric of the present invention, the inelastic yarn runner is larger than the elastic yarn runner, the inelastic yarn runner is 70 to 150 cm / rack, and the elastic yarn runner is 50 to 120 cm / rack. It is preferable to knit. This is because the above-mentioned stretchable knitted fabric is stabilized and becomes moderately stretchable.

  Preferably, the stretchable warp knitted fabric of the present invention has been subjected to presetting and / or heat setting. This is because the stretchable warp knitted fabric is stabilized, and the fraying of the edge of the stretchable warp knitted fabric is further suppressed.

  In the stretchable warp knitted fabric of the present invention, it is preferred that the knitting yarn is partially knitted as an elasticity-enhancing portion using an elastic yarn having a higher fineness than other portions. This is because the above-mentioned stretchable knitted fabric is useful in forming a garment that requires a part for enhancing tightening power.

  In the stretchable warp knitted fabric of the present invention, it is preferable that further elastic yarn is inserted. Alternatively, it is preferable that an additional inelastic thread is inserted. This is because a desired tightening force can be applied to the stretchable warp knitted fabric to suppress elongation.

  The bonded fabric of the present invention is a bonded fabric formed by stacking and bonding a plurality of stretchable warp knitted fabrics of the present invention. It is preferable that a plurality of sheets are laminated and bonded as described above, because the edges of the bonded fabric are prevented from fraying. In addition, such a bonded fabric is preferable because it is thin and has elasticity. In addition, it is preferable that the knitting direction of the stretchable warp knitted fabric is overlapped and stuck so that the knitting direction of the warp knitted fabric is reversed in the stacking and sticking. This is because, when they are laminated in the opposite direction and bonded together, the tearing of the bonded fabric is further suppressed.

  The garment of the present invention is a garment formed by including the stretchable knitted fabric of the present invention. This stretchable warp knitted fabric has reduced edge fraying, so it is not necessary to trim the edge of the edge, and the edge line of the garment appears in the outer garment, impairing the appearance or impairing the feeling of wearing. There is no advantage. In this garment, the stretchable knitted fabric is cut at an angle of 3 degrees or more and 177 degrees or less with respect to the knitting direction, and the edge that does not need to be trimmed becomes at least one of the clothes in the cut state. Thus, it is preferable that the cut piece be formed to include a piece having an edge that does not require trimming. This is because, in the stretchable warp knitted fabric of the present invention, if the piece is cut in this manner, the fraying of the edge portion is further suppressed even if the edge is not trimmed.

  The garment of the present invention is a garment formed including the bonded fabric of the present invention. Since the bonded fabric has reduced edge fraying, the garment does not need to be trimmed at the edges, and the edge line of the garment appears in the outer garment, impairing the appearance or wearing feeling. There is no advantage.

  The garment is cut at an angle of not less than 3 degrees and not more than 177 degrees with respect to the knitting direction of the bonded fabric, and at least one edge of the garment that does not need to be trimmed in the cut state is used. It is preferable that the cut piece is formed so as to include a piece having an unnecessary edge.

It is preferable to be formed including.

  Hereinafter, embodiments of the present invention will be further described with reference to the drawings.

(Embodiment 1)
Drawing 1 is a figure showing an example of an elastic warp knitted fabric of the present invention. 1 indicates an inelastic yarn, 2 indicates an elastic yarn, and the direction of the arrow indicates the knitting direction of the knitted fabric. This stretchable warp knitted fabric has a 1 × 1 tricot structure in which the inelastic yarn 1 and the elastic yarn 2 accompany each other, and is a stretchable knit in which both the inelastic yarn 1 and the elastic yarn 2 are knitted by an opening. It is a knitted fabric.

  As the inelastic yarn used for the stretchable warp knitted fabric of the present invention, for example, a filament yarn of a synthetic fiber such as nylon or polyester, or a semi-synthetic fiber such as rayon can be used. Nylon rich in water absorbency is suitable as a fiber for knitted fabric for innerwear. As the non-elastic yarn, a thinner one can easily increase the stitch density, while a too thin one results in a lower strength. The fineness of the inelastic yarn is, for example, 33 to 231 dtex, preferably 33 to 154 dtex, more preferably 33 to 89 dtex, and still more preferably 33 to 78 dtex. If the fineness of the inelastic yarn is 33 to 231 dtex, the knitted fabric can have a high density and a stable and strong knitting structure can be obtained. The fineness of the non-elastic yarn is more preferably 33 to 55 dtex, since the knitted fabric can be easily made to have a high density and a knitted structure having a stable and strong strength can be obtained.

  The elastic yarn used for the stretchable warp knitted fabric is not particularly limited, and for example, a polyurethane elastic yarn or its covering elastic yarn can be used. The thinner the elastic yarn, the higher the density of the knitted fabric. When the fineness of the elastic yarn is 154 dtex or more, it is possible to realize a state in which the edge is not required to be cut and the elongation is reduced. Accordingly, the fineness of the elastic yarn is preferably 15 dtex or more and 154 dtex or less for use in clothing that adheres to the body. The fineness of the elastic yarn is more preferably 15 to 100 dtex, and further preferably 33 to 88 dtex. On the other hand, an elastic yarn thicker than 154 dtex can be used for a clothing part that does not require elongation. Even if the elastic yarn has a fineness of 231 dtex or more and 396 dtex or less, a relatively soft elastic yarn can realize a state in which the cut edge is less likely to fray even after cutting. The elastic yarn having such a fineness has a low elongation, but can be used in a portion not requiring the elongation.

  The stretchable warp knitted fabric of the present invention preferably has a higher knitting density, but has a high density of, for example, more than 55 wales, preferably more than 60 wales, more preferably 65 wales per inch. , And more preferably at a high density of 70 wales or more. By knitting the knitted fabric at such a high density, the rate of the lateral elongation of the stretchable warp knitted fabric increases, and the stabilization of the stitches of the stretchable warp knitted fabric is maintained while maintaining the beauty of the stitches. Because it improves.

  Although it depends on the fineness of the knitting yarn to be used, specifically, for example, when using a 130-inch Russell knitting machine with a total number of 3600, the finishing width of the stretchable warp knitted fabric is 100 to 140 cm ( In general knitted fabrics, the finishing width is around 160 cm), more specifically, 110 cm, 120 cm, 130 cm, etc., and knitted at a high density as much as possible, It is desirable to improve the stability while maintaining.

  In the stretchable warp knitted fabric of the present invention, the inelastic yarn runner is larger than the elastic yarn runner, and the inelastic yarn runner is 70 to 150 cm / rack, and the elastic yarn runner is 50 to 120 cm / rack. It is preferable to knit.

  The inelastic thread runner preferably ranges from 85 to 120 cm / rack, more preferably from 95 to 115 cm / rack. The runner of the elastic yarn is preferably in the range of 70 to 110 cm / rack, more preferably 75 to 105 cm / rack. The ratio of the runner of the elastic yarn to the runner of the non-elastic yarn is preferably about 75 to 90%. When the inelastic yarn runner is made larger than the elastic yarn runner, it is possible to impart appropriate expansion and contraction of the stretchable warp knitted fabric in the lateral direction.

  Here, the "runner" refers to the length (cm) of a yarn used to knit a certain number of courses (this is called "rack", and usually 480 courses are defined as one rack).

  The ratio (A / B) of the runner A of the inelastic yarn and the runner B of the elastic yarn in the stretchable warp knitted fabric is preferably 1.15 or more, more preferably 1.2 or more, and still more preferably 1.3. That is all.

  The stretchable knitted fabric used in the present invention that can form an edge that does not need to be trimmed as it is cut does not include lace fabric.

  It is preferable that the stretchable knitted fabric is subjected to presetting and / or heat setting. This is because such processing can improve the effects such as stability of the knitted fabric and prevention of fraying. The preset and heat setting are higher than a certain temperature, depending on the shape of the processing apparatus, the preset processing time, the heat setting processing time, the type of the stretchable warp knitted fabric, the thickness thereof, and the like. The reaction can be performed at a temperature, for example, a temperature higher than 180 ° C, preferably a temperature higher than 185 ° C, more preferably a temperature range of 190 ° C to 195 ° C. For example, when an apparatus having a configuration of 6 chambers is used at a temperature higher than 180 ° C., the processing time is, for example, about 15 to 40 m / min, and preferably about 20 to 26 m / min.

  In the above-mentioned stretchable knitted fabric, an elastic yarn having a fineness partially larger than other portions is used as a knitting yarn, and a knitted fabric portion whose tightening power is desired to be strengthened can be integrally knitted. This means that the elastic yarn is knitted in a tricot knit structure forming a loop. For example, such a stretched knitted fabric piece or a bonded fabric obtained by laminating a plurality of pieces thereof is useful for forming clothes, bags, and the like that partially require a tightening power enhancement portion. It is also useful for reducing manufacturing costs. In addition, an elastic yarn and / or an inelastic yarn are inserted into the stretchable warp knitted fabric, and the fineness and density of the inserted yarn are appropriately adjusted to knit a knitted fabric having a required elongation and stretchable power. Alternatively, the stability of the stitch can be improved. In addition, a pattern thread may be appropriately inserted in order to provide fashionability.

  The elastic warp knitted fabric can be easily knitted by known means by appropriately selecting a single machine or a double raschel machine such as a raschel knitting machine or a tricot knitting machine based on the required knitting conditions. it can. The knitted fabric can be subjected to various post-processings as needed, for example, by applying various patterns by dyeing, heating embossing, or punching to increase added value.

  The above-mentioned stretchable knitted fabric can be used alone as a knitted fabric having little edge fraying and no need for edge trimming. When the above-mentioned stretchable knitted fabric is used alone as a knitted fabric, it is preferable to perform, for example, presetting and / or heat setting. This is because the stitch of the thermoplastic knitting yarn is stabilized by the heat of the presetting and / or heat setting.

(Embodiment 2)
In the present embodiment, a preferred embodiment of the bonded fabric of the present invention will be described. The stretchable warp knitted fabric may be bonded to a plurality of pieces and laminated to form a bonded fabric. Such a bonded fabric is thin and has beautiful stitches on both sides, and can be used very suitably for reversible clothing and the like. The stretchable warp knitted fabric may be stuck with the knitted fabrics to be stuck together in the same or opposite directions, but is preferably stuck in the opposite direction. This is because, when bonding is performed in the opposite direction, tearing from the edge is suppressed. The stretchable knitted fabric usually has the front surface of the knitted material facing outward and the back surface serving as a bonding surface.

  The stretchable warp knitted fabric may be combined with a cloth or film other than the stretchable warp knitted fabric, and may be overlapped and bonded. As the cloth, for example, a cloth such as another warp knitted fabric, a weft knitted fabric, a jersey, a woven fabric, or a nonwoven fabric can be appropriately selected and used depending on the purpose. The number of layers of the cloth or film is not limited.

  Examples of the bonding means of the stretchable warp knitted fabric or the like include, for example, a method of thermally fusing a directly stacked cloth or the like, a fusing method of fusing and sandwiching urethane foam between cloths to be bonded, acrylic, A method of bonding using an adhesive such as urethane-based, polyester-based, or fusible powder may be used. There are a doctor method, a roller method, an inversion method, a spray method, and the like as a method of bonding using an adhesive, and these means can be appropriately selected.

  The bonded fabric of the present invention can be subjected to various post-processing as needed to increase added value. For example, a required pattern may be provided by printing, heating embossing, punching, or opal processing, and a required molding may be performed by molding for use in a brassiere cup or the like.

(Embodiment 3)
In the present embodiment, a preferred embodiment of a garment including the stretchable warp knitted fabric of the present invention will be described.
The clothing of the present invention may be formed by using at least partly the stretchable knitted fabric of the present invention, and is not limited thereto.

  In the garment of the present invention, at least one or both of the upper edge and the lower edge of the piece of the garment formed from the stretchable warp knitted fabric is composed of an edge that does not need to be trimmed while being cut. It is preferable that the unnecessary edge is cut at an angle of 3 to 177 degrees, preferably 10 to 120 degrees with respect to the knitting direction. This makes it possible to form a garment that fits the wearer's body without fraying or curling.

  In the garment of the present invention, the piece formed from the stretchable knitted fabric of the present invention is preferably made of a stretchable knitted fabric that is continuous from the upper edge to the lower edge in the up-down direction of the garment.

  In the garment of the present invention, at least one or both of the upper edge and the lower edge of the piece of the garment formed from the stretchable warp knitted fabric of the present invention comprises an edge that does not need to be trimmed while being cut. It is preferable that the unnecessary edge is cut into a curved line.

  In the garment of the present invention, at least one or both of the upper edge and the lower edge in the garment of the piece formed from the stretchable warp knitted fabric of the present invention comprises an edge that does not require trimming while being cut, It is preferable that the unnecessary edge is a wave shape having a plurality of curves.

  In the garment of the present invention, both the upper edge and the lower edge of the piece of garment of the warp knitted fabric of the present invention are composed of edges that do not need to be trimmed as they are cut, and the upper edge and the lower edge Are not parallel to each other, or the shape of the upper edge and the shape of the lower edge are preferably different. Alternatively, the upper and lower edges are preferably non-parallel to each other and have different shapes.

  Examples of the clothing of the present invention include bottom clothing (eg, shorts, long girdle, etc.), brassieres, swimwear, leotard tops, and the like.

  In the bottom garment, the edge which does not need to be trimmed in the state where the piece is cut by the warp knitted fabric of the present invention forms at least one or both of the waist and the hem. In this case, the edge of the piece that does not need to be trimmed while being cut is an edge cut at an angle of 20 to 80 degrees, more preferably 35 to 65 degrees with respect to the knitting direction. preferable.

  In a bra, or a swimsuit or a leotard top, an edge that does not need to be trimmed while the piece is cut by the stretchable warp knitted fabric of the present invention is at least one or both of an upper edge and a lower edge of a back cloth. Are preferably formed. In this case, the unnecessary edge of the piece forming the back cloth is cut at an angle of, for example, 10 to 90 degrees with respect to the knitting direction, preferably 75 to 90 degrees with respect to the knitting direction. Is also good.

  The cutting angle will be described with reference to FIG.

  In FIG. 2, it is assumed that a portion surrounded by ABCDA is a cut piece. Arrows E, F, and G indicate the knitting directions of the knitted fabric. The X side in FIG. 2 is referred to as a “knitting start side”, and the Y side in FIG. 2 is referred to as a “knitting end side”. Therefore, the edges AD and the edges CD are referred to as edges on the knitting start side, and the edges AB and BC are referred to as edges on the knitting end side.

  In the case of the edge (AD or CD) on the “knitting start side”, the edge cutting angle is the acute angle (α4 or the angle) formed by the edge line and the knitting direction. α3). In the case of the edge on the “end of knitting” (AB or BC), the angle (α1 or α2) which is an obtuse angle among angles formed by the edge line and the knitting direction is referred to.

  The above is the definition of the edge cutting angle in the present invention. For ease of explanation, for example, in FIG. 2, the edge AB line cutting angle may be described using the angle β1. This is easily understood from the above definition of the edge cutting angle that the edge AB line cutting angle is "180 degrees-β1 degree".

  By setting the cutting angle of the edge line to the aspect of the present invention as described above, the fit to the body of the edge that does not need to be trimmed while being cut is improved, and the edge portion is the body of the wearer. It is preferable because curling outward can be prevented. That is, in the state of being cut, the edge that does not need to be trimmed, the upper edge or the lower edge of the clothing, for example, clothing having a waist or a hem, the edge portion may curl to the outside of the wearer's body. is there. In order to prevent such curling, it is preferable to cut the cutting line at a portion that becomes the edge that does not need to be trimmed at an angle described above with respect to the knitting direction of the knitted fabric. The knitting direction of the knitted fabric corresponds to the yarn supply direction when knitting the knitted fabric. In the above description, 20 to 80 degrees with respect to the knitting direction is an angle of 20 to 80 degrees on either side of the knitting direction assuming a line in the knitting direction, in other words, an angle of The angle at which the vertex is facing, which is ± 20 to 80 degrees with respect to the line in the knitting direction.

  In addition, when using an edge that does not need to be trimmed as it is cut to a portion that does not need to prevent curling outside the body, use a piece that has an edge cut within 45 degrees or less. It is also preferable to do so. In addition, it is preferable to use a piece whose cut edge is not linear but cut into a waveform or the like, because the edge can be prevented from curling outside the body.

  When cutting a piece of clothing, if a plurality of edges are cut and an edge is not required to be trimmed, any one of the portions is 3 to 177 degrees with respect to the knitting direction, for example, a preferable range of 20 to 80 degrees. There are some places where cutting cannot be performed at a degree, and for example, cutting must be performed at an angle of less than 20 degrees in the knitting direction. If such an edge is cut into a waveform, the cutting angle of the edge having a waveform curve can be set to, for example, a preferable range of 20 to 80 degrees, and the entire edge is substantially at 20 to 80 degrees. The effect of cutting can be obtained. Due to the design of the garment, both edges are not required, such as when the waistline and hem of the short girdle are trimmed together using a single piece of clothing that is continuous in the up and down direction to make the rim unnecessary. In some cases, the part cannot be cut at 20 to 80 degrees with respect to the knitting direction, and in such a case, it is preferable to make one edge a wavy edge.

  In particular, in bottom clothing such as girdles and shorts, using the edge of the piece cut at the above angle for the waist or hem can prevent fraying and curling of the edge.

  In the case of a bra, a swimsuit or a leotard top, the back cloth is cut at a right angle to the knitting direction or at an angle such as ± 20 degrees to the parallel or close to a right angle. It is preferable because the elongation can be given in the lateral direction when worn, and the feeling of wearing is improved. The back cloth has a substantially trapezoidal shape that narrows from the side of the cup toward the rear center connection part called hook and eye, and the upper edge and the lower edge have a relationship of two oblique sides of an isosceles triangle. Many. Therefore, one of the upper edge and the lower edge of the back cloth is cut at preferably 10 to 90 degrees, more preferably 75 to 90 degrees with respect to the knitting direction. Assuming that the cutting angle of one edge is α, the other edge is cut at an angle close to (180−α) degrees. For example, when cutting at an angle close to a right angle, the lower edge of the back cloth is cut at 100 degrees, and the upper edge is cut at 80 degrees. When cutting at an angle nearly parallel to the knitting direction, the upper edge of the back cloth is cut at 15 degrees, and the lower edge is cut at 165 degrees. In this way, even if the piece of the back cloth is cut at an angle other than an angle close to or parallel to the knitting direction, if the cut shape is a corrugated shape having a plurality of curves, the edges may be frayed. Curling does not occur, and it has a certain degree of elongation. "Wave shape with multiple curves" is not simply a convex or concave curve in one direction, but a curve that is convex in one direction and a concave This means a curve formed by combining a plurality of curves, such as a wavy line. The “wave shape having a plurality of curves” means a so-called “wave shape” curve. The wave shape is not limited to the one formed by repeating a regular simple curve, and may be an irregular wave shape.

  When the shape of the edge as it is cut is made into a wave shape, it is preferable that the curvature of the curve of each wave shape is not so small that the tear strength does not decrease and that the edge portion is less likely to be turned up. .

(Embodiment 4)
In the present embodiment, a preferred embodiment of a garment formed including the bonded fabric of the present invention will be described.
When using the bonded fabric to form a laminated piece that forms a garment, a plurality of the stretchable warp knitted fabrics may be stacked in advance and cut into a desired shape. Alternatively, each of the stretchable warp knitted fabrics may be cut in a predetermined same shape, and a plurality of these may be laminated and bonded. In any case, the plurality of pieces to be bonded are joined and laminated in the same shape to substantially form one bonded fabric. Therefore, no step occurs in the pieces of the bonded fabric of the present invention. In addition, since the stretchable warp knitted fabric of the present invention, which does not cause fraying even by one sheet, is adhered, the edge of the piece of the bonded fabric is not cut off and the edge of the thread is not projected, and the edge is clean. Can be. The method of bonding is as described above.

    The present invention will be specifically described with reference to examples. This example does not limit the scope of the present invention.

Using a 130-inch Russell knitting machine, use two layers of inelastic yarn with a fineness of 44 dtex and 34 filaments of microfludar nylon yarn, and use an elastic yarn with a transparent polyurethane yarn of a fineness of 44 dtex. A 1 × 1 tricot of eyes was knitted. Since the total number was 3600, the finished width of the knitted fabric was generally set to about 160 cm, but in this example, it was set to 130 cm (about 70 wells / inch) and finished as narrow as possible. The runner of nylon yarn was set to 110 cm / rack where it should be set to 80 cm / rack or less in a normal knitted fabric, and the runner of nylon yarn was set to 95 cm / rack when it was usually set to 60 cm / rack or less. After knitting, heat setting was performed at a heating temperature of 192 ° C. and a slightly longer time of 20 m / min using a 6-chamber apparatus to obtain a stretchable warp knitted fabric. The appearance of the obtained stretchable warp knitted fabric was orderly and the edges were hard to be unraveled and extremely attractive. The tear strength in the vertical direction was measured and found to be 20 to 90 N. The inelastic yarn runner / elastic yarn runner (A / B) of the stretchable warp knitted fabric was 1.158, and had a density of 68 wales per 2.54 cm.
Then, the obtained stretchable warp knitted fabric of the present invention was adhered by using an adhesive dot having a diameter of about 0.5 mm in about 60 places per 1 cm ² using an adhesive of about 5 g per 1 m of knitted fabric, and having a thickness of about 0.5 mm. It was processed into 1 mm stretchable bonded fabric samples A and B. In Sample A, the knitting directions of the knitted fabrics were aligned, and in Sample B, the knitting directions of the knitting were reversed. When the tear strength in the vertical direction of these elastic bonded fabrics was measured, A was 110 N to 120 N and B was 220 N to 250 N. In the present invention, the tear strength is the average value of the values measured for three samples at a tensile speed of 300 mm / min using the Shimadzu Autograph AGS-H50N by the Wacoal method mutatis mutandis JIS L-1018. is there.

  FIG. 3 is a perspective view of a main part of a bra using a warp knitted fabric having an edge that does not need to be trimmed as a back cloth in the cut state of the present invention. FIG. 4 is a plan view showing a cutting line of the back cloth piece 11 corresponding to the left side of the wearer of the brassiere shown in FIG. In FIG. 3, 11 is an elastic back cloth, 14 is a base part, 15 is a front center part, 18 is a connecting part for connecting the left and right back cloths when worn, 16 is a breast cup, 17 is a strap, Reference numeral 19 denotes a left and right front central suturing portion. The back cloth part, the base part, and the front center part are formed from one continuous cloth. The stretchable back cloth 11 is a piece that does not need to be trimmed while being cut, and is formed of a cloth that is continuous in the vertical direction. The knitting direction of the warp knitted fabric constituting this piece is the direction indicated by arrow 23 (see FIG. 4).

  The back cloth piece 11 is formed by bonding and laminating two pieces forming the back cloth with a heat-adhesive resin, that is, bonding them in order to impart strength to the back cloth. A piece in which two knitted fabrics were laminated so that the knitting directions were opposite to each other was used. As the piece forming the back cloth, a nylon thread 44 dtex was used as the non-elastic yarn, and a polyurethane thread 78 dtex was used as the elastic yarn (the mixing ratio was 65% by weight of the nylon yarn and 35% by weight of the polyurethane yarn). A warp knitted fabric with accompanying 1 × 1 tricot structure, inelastic yarn and elastic yarn both knitted with open stitches, using a knitting density of 68 / inch (2.54 cm) of wale, these two knitting The resin was superimposed and bonded with resin so that the knitting direction of the ground was reversed, and then cut into the shape of the back cloth shown by 11 in FIG. 4 and used as a back cloth part.

  The edges of the back cloth 11 that do not need to be trimmed in the cut state are the lower edge (abbreviated as “lower edge”) 13 and the upper edge 12 (abbreviated as “upper edge”). ) Part. Each of the lower edge 13 and the upper edge 12 has a wave shape having a plurality of waveforms.

  At the upper edge 12 and the lower edge 13 of the back cloth, the wave-shaped irregularities appear at substantially the same intervals, and among the wave shapes of the upper edge 12, the wave at the lower edge 13 at the lower position corresponding to the position of the upwardly convex shape. The shape is convex downward, and conversely, the wave shape of the lower edge 13 at the lower position corresponding to the position of the wave shape of the upper edge downward (concave shape upward) is convex upward. The upper and lower edges of the back cloth are substantially symmetrical in shape, with the shape of the upper and lower edges of the back cloth being symmetrical. Further, each of the wave shapes of the wave shapes formed on the back cloth is a gentle curve (a curve with a large radius of curvature), and the wave shape is a long wave shape with a small difference in height and a gentle wavelength. In other words, it is shaped like peas pods. By making the wave shape a long wave and a gentle wave shape with a small difference in height, the fit of the back cloth to the body is improved, the turning of the upper and lower edges can be prevented, and especially from the valley part of the wave shape Can be prevented from easily becoming torn.

  In addition, at the upper edge and the lower edge of the back cloth, the intervals at which the plurality of wave-shaped waves appear are almost the same at the upper edge and the lower edge, and the heights of the wave shapes are also substantially the same, and at the upper edge and the lower edge, The place where the irregularities appear is shifted, and among the wave shapes of the upper edge, the wave shape of the lower edge at the lower position corresponding to the position of the upwardly convex shape is upwardly convex, and conversely, the wave of the upper edge is The wave shape of the lower edge 13 at the lower position corresponding to the position where the shape is downwardly convex (upwardly concave) may be downwardly convex (upwardly concave).

  Also, the upper green 12 of the back cloth 11 is a gentle curve projecting downward as a whole when irregularities due to individual wave shapes are neglected, and the gentle curve part has a gentle curve part. The lower green 13 of the back cloth 11 is a gentle curve that protrudes upward as a whole when the irregularities due to the individual wave shapes are neglected, and the gentle curve portion includes four gentle green curves. It has a shape with a wave curve.

  Therefore, since the direction of the edge line of the lower edge 13 of the back cloth 11 is generally curved, the end of the lower edge 13 of the back cloth closer to the breast cup side and the end closer to the coupling portion 18 side. Is the same direction as the straight line connecting, that is, the direction indicated by the arrow 22, and has an angle of 85 degrees (cutting angle) with respect to the knitting direction. The direction of the edge line of the upper edge 12 is the same direction as the straight line connecting the vertices of the waveform, that is, the direction indicated by the arrow 21, and is 105 ° (cutting angle) with the knitting direction. I have. That is, the lines constituting the edges that do not need to be trimmed in the state where the upper and lower sides of the back cloth are cut are not parallel to each other. Since the edge line has a wavy shape, the wavy portion of the edge line of the lower edge 13 is at an angle of about 85 degrees, and the wavy portion of the edge line of the upper edge 12 is 105 degrees. It is cut at an angle back and forth. The base portion 14 and the front center portion 15 are cut at an angle of approximately 75 degrees with respect to the knitting direction.

  24 protruding linearly from the upper edge of the back cloth is a strap attachment portion, and the strap 17 is attached to the tip. The strap attaching portion 24 is continuous with the back cloth 11 and is cut integrally with the back cloth. The edges are cut and need not be cleaned. The width of the back cloth 11 was 9 cm at the widest point and 4 cm at the narrow point.

  In addition, the wave shape of the upper edge and the wave shape of the lower edge may be shapes having different intervals of wave expression, different wave heights, or different numbers of waves.

  Further, the wave shape of the upper edge and the wave shape of the lower edge may be shapes having different intervals of wave appearance, different wave heights, and different numbers of waves.

  In the conventional back cloth of the brassiere, the rubber tape is provided along the upper and lower edges of the back cloth 11, but since the upper and lower edges of the back cloth 11 of the brassiere of this embodiment are not sewn with the rubber tape, There is no increase in thickness due to the rubber tape, and the silhouette around the chest when worn can be made a neat silhouette, and no trace of tightening of the rubber tape remains on the skin. Therefore, the back cloth fits on the body, the displacement that occurs during exercise is minimized, and the fall of the clothes is also prevented. Also, it is possible to effectively prevent the edge of the back cloth from being turned up.

  Since the back fabric is formed by laminating the two knitted fabrics, the tear strength is large, and the upper edge and the lower edge of the back fabric are edges that do not need to be trimmed, and are formed from a vertically continuous fabric. From the upper edge to the lower edge, the surface is flat and has no steps, so that there is no partial compression when worn. The knitted fabric used as the back cloth piece is a cloth whose cut edges do not fray, and is cut into a shape and angle that does not cause fraying, so the cut edges of the upper and lower edges are clean. Therefore, the yarn does not protrude.

  In addition, using the laminated product of these two knitted fabrics as a piece for forming clothing can form not only a back cloth of a bra, but also a bottom such as shorts and a girdle, a lingerie and an undergarment. .

  A brassiere was prepared in the same manner as in Example 2 except that the back knitted fabric piece 11 of the present invention in which two warp knitted fabrics were laminated in the same direction was used.

  FIG. 5 is a rear view of the shorts formed by using the warp knitted fabric of the present invention having edges that do not need to be trimmed as they are cut, and FIG. 6 is a front view of the shorts shown in FIG. FIG. 7 is a plan view showing a cutting line of the front flank-side-hip-fitting portion 36 corresponding to the left side of the wearer of the shorts shown in FIGS. 5 and 6 on a knitted fabric.

  In FIGS. 6 and 7, reference numeral 36 denotes a front flank-side-hip portion covering the front flank-side-back portion, which is a single piece that is continuous in the vertical direction and has no level difference. Reference numeral 37 denotes an abdomen-crotch portion covering portion that covers the abdomen and the crotch portion, and is composed of one piece that is continuous in the vertical direction and has no step. The left and right front flank-armpit-hip-fitting pieces 36 are sewn to each other at the rear center suturing line 39, and the front side edge of the front flank-armpit-hip-fitting piece 36 is abdomen-crotch. A part of the side edge of the part filling part 37 is sewn to each other at a suturing line 40. That is, the shorts are formed of three best-looking pieces.

  In FIG. 7, the line MNOOPQM shown in the fabric 70 is a front flank-armpit for obtaining a piece of the left half of the wearer used for the hip from the side of the shorts. -It shows the cutting line of the hip applicator piece 36.

  Although not shown, the shape of the right half of the front flank-side-hip-fitting portion 36 is symmetrical to the shape of the left half. The MN line is sewn to a part of the abdomen-crotch portion filling piece 37 in FIG. 6, and the PQ line is sewn to a similar part of the above-mentioned right half piece (not shown) so as to be in the center of the rear. A suturing line 39 will be formed. The OP line is sutured with the crotch rear part 42 of the abdomen-crotch part fitting part 37. The N-O line forms a skirt line (N-R line of the N-O line is a front skirt line 45, the R-O line is a rear skirt line 43), and the QM line forms a waist line 44. . The same applies to the sewing of the above-mentioned right half piece 36 (not shown) because the right and left pieces 36 are symmetrical. Thus, the shorts shown in FIGS. 6 and 7 can be created.

  The front flank-side-hip-part allocating part 36 and the abdomen-crotch-part allocating part 37 are cut off and use unnecessary parts. The knitting direction of the warp knitted fabric constituting the front flank-side-hip portion applicator 36 is the direction indicated by the arrow 35.

  The front flank-armpit-hip portion allocating piece 36 and the abdomen-crotch portion allocating piece 37 allow the knitting structure of the ground knit portion to accompany a 33 dtex nylon yarn and a 77 dtex polyurethane yarn as described with reference to FIG. The elastic yarn and the non-elastic yarn are knitted at a knitting density of 70 wales per inch (2.54 cm) with a 1 × 1 tricot structure. It should be noted that a small pattern 38 is provided on the surface of the plain fabric by printing.

  The edge of the front flank-side-hip-fitting portion piece 36 which is not required to be trimmed in the cut state forms the edges of the front hem 45, the rear hem 43, and the edge of the waist 44. are doing. The rear skirt line 43 has a waveform, and the direction of the rear skirt line 43 is the same direction as the straight line connecting the vertices of the waveform, that is, the direction indicated by the arrow 33, and the knitting direction 35 has an angle of 5 degrees. Is attached. As shown in FIG. 7, the front hem line 45 (N-R) has an irregularly curved shape slightly upwardly convex. The waistline 44 is cut at an angle α (cutting angle) of 3 degrees with respect to the direction of the knitting direction 35. Therefore, the skirt line 43 and the waist line 44 are non-parallel.

  As described above, the upper edge 46 of the abdomen-crotch portion applying portion piece 37 is an edge that does not need to be trimmed as it is cut. As the knitted fabric, the same knitted fabric with the same floral pattern printed on the surface as that of the front flank-side-hip-part fitting portion piece 36 was used.

  The abdomen-crotch portion applicator piece 37 does not show the knitting direction or the direction of the cutting edge, but the upper edge 46 of the abdomen-crotch portion applicator piece 37 is at an angle of 45 degrees to the knitting direction. Used after cutting.

  By doing so, it is possible to make the edge of the waist and the hem that has not been trimmed while cutting all the edges of the garment, and to form shorts with a vertically continuous piece without steps. Therefore, it is possible to provide shorts with a small pattern of flowers with a small number of sewing locations and a flat surface with few steps. In particular, the step at the edge can be eliminated, the cutting angle is 3 degrees or more (180-3 = 177 degrees or less) with respect to the knitting direction, and the waist line and the hem are cut by making the cutting shape a curve or a waveform. Even if it is left as it is, it does not fray and adheres to the body without curling, it is hard to be displaced, and the waist and hem are easily held at a stable position, which is preferable.

  As described above, the hem lines 43 and 45 and the waist line 44 are edges that do not need to be trimmed as they are cut, and do not need to be trimmed and do not use rubber tape or the like. In this way, the waist is not strongly tightened in a linear manner, and the thickness is not increased, so that the silhouette around the waist when worn can be made a clean silhouette, and the tightening mark of the rubber tape does not remain on the skin. The same applies to the circumference of the skirt. The front flank-side-hip-part allocating piece 36 and the abdomen-crotch-part allocating piece 37 are not limited to the above-described knitting structure, but may be any other knitting structure as long as the tricot warp knitted fabric does not fray while being cut. good.

  The shorts may be formed in a plain color without printing on the surface.

  In addition, the warp knitted fabric of the present invention can be used not only for shorts but also for long girdle.

  The stretchable warp knitted fabric of the present invention can also be applied to uses for forming clothing.
