Description

  The present invention is suitably used for producing clothing that is easy to move while producing sufficient volume in the knitted fabric thickness to provide heat retention while also providing flexible stretchability (elongation). It relates to a stretch stretch knitted fabric.

  As a circular knitted fabric (cylindrical fabric) knitted using a double circular knitting machine equipped with a cylinder and a dial, a knitted fabric that is light and has a volume is known (see, for example, Patent Document 1). This known knitted fabric has a single knit by a cylinder-needle (for example, when a plurality of yarn feeders are provided in the course direction with the direction in which the yarn runs (circumferential direction of the cylinder or dial) being set as the course direction. , Flat knitting) course, single knit course with dial needle, and course with plating knitting on the dial needle side as a tack and cylinder-needle side as a knit so as to form a knitting structure It has become.

  On the other hand, as other tubular fabrics, knitted fabrics that have been raised to increase heat retention are known (see, for example, Patent Document 2). Also for this known raised knitted fabric, when a plurality of yarn feeders are provided in the course direction and knitted, the single knit course with the cylinder needle, the single knit course with the dial needle, and the dial needle side are tacked. The knitting structure is configured by combining the cylinder side with the knit course. The needle loop on the cylinder-needle side is raised in the course in which the dial needle side is tack and the cylinder-needle side is knit.

Japanese Patent Laid-Open No. 62-141161 JP 2000-256945 A

  None of the known knitted fabrics disclosed in Patent Documents 1 and 2 have a course knitted into a double knit (for example, rib knitting) because they do not place importance on stretchability. It was not enough. Therefore, when these knitted fabrics were used, it was not possible to produce a garment having both the volume feeling of the knitted fabric thickness and the stretchability.

The present invention has been made in view of the above circumstances, and generates sufficient volume in the knitted fabric thickness to provide heat retention, while also making flexible stretchability (extensibility) rich and easy to move. An object of the present invention is to provide a thickness stretch knitted fabric that can be suitably used for producing clothing.
It is another object of the present invention to provide a ground thickness stretch knitted fabric having a knitting structure that does not cause inconvenience such as snacking and expansion of knitted fabric fraying due to occurrence of a run even by enriching stretch properties.

In order to achieve the above object, the present invention has taken the following measures.
That is, the thickness stretch knitted fabric according to the present invention includes a tack course knitted including a tack, and a course covered with a tack loop of the tack course when the course direction is a direction in which the yarn is run during knitting. At least two courses are formed of a knitting structure by plating each having a ground yarn and a splicing yarn.

When the knitting direction intersecting the course direction is set as the wale direction, two courses arranged on both sides of the wale direction with respect to the tack course are composed of a knitting structure in which no tack is present. be able to.
Alternatively, a plurality of the tack courses may be continuously arranged in the wale direction.

In the knitting structure by the plating, the splicing yarn is a welding yarn, and the tack course and the course covered with the tack loop of the tack course are fused or bonded by the welding yarn. it can.
The ground yarn and the splicing yarn constituting the knitting structure of the plating are selected so that there is a difference in contraction rate between them, and the ground yarn and the splicing yarn are mutually loop-shaped at the time of shape stabilization after contraction. It is preferable that the yarn is formed with a yarn feeding length that allows the two to come close to each other.

Here, the shrinkage of the ground yarn and the splicing yarn may be based on the elasticity of the yarn material, or may be based on heating (steam, heated air, press, etc.) applied after knitting.
In addition, the shrinkage of the ground yarn and the splicing yarn, particularly when the loop with the larger shrinkage rate (yarn) shrinks, causes a tightening action to constrain the loop with the smaller shrinkage rate (yarn) in shape. In view of this, it is preferable to select the ground yarn and the splicing yarn (as the relationship between the shrinkage rate and the yarn feeding length).

  The fabric thickness stretch knitted fabric according to the present invention produces a sufficient volume of knitted fabric thickness to provide heat retention, while also making flexible stretchability (extensibility) abundant and making clothes that are easy to move. For example, it can be suitably used. Further, the thickness stretch knitted fabric has a knitted structure that is rich in stretchability but does not cause inconvenience such as snacking and expansion of the knitted fabric fraying due to occurrence of run.

It is the organization chart which showed 8th Embodiment of the ground thickness stretch knitted fabric which concerns on this invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 and 2 show a first embodiment of a ground thickness stretch knitted fabric (hereinafter referred to as “the knitted fabric of the present invention”) 1 according to the present invention. As is clear from FIGS. 1 and 2, the knitted fabric 1 of the present invention includes a tack course 3, and this tack course 3 has a knitted structure knitted with a base yarn 4 and a splicing yarn 5. ing.

The tack course 3 is pulled up to a loop that forms a parallel course at least one place in the course direction (the direction in which the yarn is run during knitting, which is the left-right direction in FIGS. 1 and 2). It has a tack loop 3a. Needless to say, the tack loop 3 a is formed by the ground yarn 4 and the splicing yarn 5.
In this tack course 3, the loop shape of the tack loop formed by the ground yarn 4 and the loop shape of the tack loop formed by the spliced yarn 5 are close to each other (the size of the loop is substantially the same). A heavy loop is obtained.

FIG. 1 and FIG. 2 illustrate a case where the tack course 3 is a single tack and a full tack in which all loops are tacked. Therefore, the tack loop 3a is put on all the loops 8a of the course 8 adjacent to the tack course 3 in the wale direction (the knitting direction intersecting the course direction and the vertical direction in FIGS. 1 and 2). ing.
And in the knitted fabric 1 of the present invention, the course 8 having the loop 8a covered by the tack loop 3a of the tack course 3 as described above is also a knitted structure knitted with the base yarn 12 and the splicing yarn 13. Yes.

In the first embodiment, the course 8 adjacent to the tack course 3 is a double knit course knitted by a double knit such as a rib knitting. In the double knit course 8 as well, the loop shape formed by the ground yarn 12 and the loop shape formed by the spliced yarn 13 are arranged to closely approach each other when the shape is stabilized after shrinkage.
Thus, in the knitted fabric 1 of the present invention, since the tack loop 3a and the loop 8a covered by the tack loop 3a are both knitted by plating, the [ground yarn 4 and the splicing yarn 5] and the [ground fabric] A quadruple loop 15 composed of the yarn 12 and the splicing yarn 13] is formed. Accordingly, the presence of the quadruple loop 15 enables the knitted fabric 1 of the present invention to generate a volume sufficient for the knitted fabric thickness.

In addition, the knitted fabric 1 of the present invention employs the following configuration. That is, in the tack course 3, the ground yarn 4 and the splicing yarn 5 constituting the knitting structure of the plating are selected so as to cause a difference in contraction rate.
What is important here is that the loop shape of the tuck loop formed by the ground yarn 4 and the loop shape of the tuck loop formed by the spliced yarn 5 are close to each other even after the yarn having the larger shrinkage rate contracts. There is in point.

Therefore, after knitting, the loop with the larger shrinkage rate (yarn) is contracted to constrain the loop with the smaller shrinkage rate (yarn) in shape and tightened so that the tack loop 3a does not become excessive. A compact and beautiful multiple loop is obtained.
This not only further enhances the volume-up effect of the knitted fabric thickness, but also the free-cut property (the so-called “cut” effect) that the knitting structure does not loosen or collapse no matter where the knitted fabric is cut. ) Can also be obtained. In addition, since the problem that the yarn end jumps out at the end of the knitted fabric can be solved, when the garment is made by the knitted fabric 1 of the present invention, the knitted fabric suffers from the pain of the knitted fabric caused by repeated wearing and taking off or washing. It is extremely useful in that the effect of suppressing these can be achieved.

  In selecting the base yarn 4 and the splicing yarn 5, in order to make a difference in the contraction rate between them, for example, a heat shrink yarn is used only for the base yarn 4, and the yarn supply length is contracted. This can be realized by setting it to be extended for a long time so as to meet the amount. By doing in this way, after the knitting, the ground yarn 4 which is a heat-shrinkable yarn contracts more than the splicing yarn 5, and a tightening action is generated so as to constrain the loop of the splicing yarn 5 in shape.

For such heat-shrinkable yarn, for example, short fibers such as bulky acrylic can be used.
As the heat shrinkable yarn, it is preferable to employ one having a boiling water shrinkage of 8% to 45%. If the boiling water shrinkage is less than 8%, the loop restraining action is poor and the volume of the knitted fabric may be insufficient and the free-cut property may be insufficient. Conversely, if the boiling water shrinkage exceeds 45%, The knitted fabric volume may become too thick or the basis weight may become excessive due to the strengthened loop restraining action.

However, since it is not always required to satisfy all of the knitted fabric thickness, basis weight, etc., a heat shrinkable yarn (for example, polyester yarn) having a boiling water shrinkage rate of less than 8% or a boiling water shrinkage rate. The use of heat shrinkable yarn exceeding 45% may be acceptable depending on the content of the request as a knitted fabric.
In selecting the base yarn 4 and the splicing yarn 5, in order to make a difference in the contraction rate between them, one of the yarns is used as an elastic yarn and greatly stretched during knitting. It can also be realized by adopting a method.

By the way, the tack course 3 is mainly intended to give volume to the knitted fabric thickness, whereas the double knit courses 8 and 17 are mainly intended to increase the stretchability (elongation) of the knitted fabric. It can be said that it is aimed.
Therefore, in the main yarns 4, 12, and 18 (yarns that often appear as the knitted fabric surface side) that are the main components of the knitting structure and the accessory yarns 5, 13, and 19 (yarns that often appear as the inner side of the knitted fabric), It is better to select the type of yarn to be used, paying attention to the physical properties such as stretchability, strength, thickness, specific gravity, and the characteristics such as appearance, pattern, texture (texture) and heat retention. .

However, in the knitted fabric 1 of the present invention, since the tack course 3 and the double knit courses 8 and 17 are plated, the yarn type to be used is not particularly limited.
For example, as described above, heat shrink yarn is used for the ground yarns 4, 12, and 18 in expectation of a large shrinkage rate, and bare yarn or covering yarn (SCY or DCY) is used in expectation of an elastic action. Can be.

  In addition, it is effective to use bare yarn or covering yarn (SCY or DCY) for the splicing yarns 5, 13 and 19 in anticipation of an elastic action. In addition, from the viewpoint of not being “elastic”, it is possible to expect a fusion or bonding action of the structure by applying a heat setting process (heating process) to the knitted fabric after knitting. Thread) can also be used. In addition, long fibers such as nylon and polyester can be used alone or in combination in the hope of acting as an inelastic yarn, and cotton yarn or silk yarn can be used in the hope of enhancing the texture. It is.

  When the heat setting process is performed on the splicing yarns 5, 13, and 19 using a welding yarn, the tack course 3 and the course 8 having the loop 8 a covered by the tack loop 3 a of the tack course 3 are made of fibers. At the intersections and parallel portions of the two, they are fused or joined together by welding yarns. Thereby, there exists an advantage which can improve further the free cut property and the yarn end pop-out prevention action of the knitted fabric end.

Assuming that the tuck course 3 is not plated, the volume of the knitted fabric is considered to generate volume. For example, the knitted fabric is knitted with a double knit such as a conventionally known rib knitting and used. In general, a method of increasing the yarn count and yarn feeding length (using a thick yarn and increasing the feeding length) is employed.
However, in the knitted fabric knitted by this conventional method, the basis weight (weight) becomes heavy, and there are problems such as a decrease in stretchability. If this double knit is plated, etc., there is a risk that the weight of the fabric will be further reduced and the stretch will be reduced.

On the other hand, in the knitted fabric 1 of the present invention, since such a problem is not involved, it is possible to obtain a knitted fabric which is light and thick and has abundant stretch properties.
In the first embodiment, the second double knit course 17 is arranged after the double knit course 8. In short, the knitted fabric 1 of the present first embodiment is configured as a so-called three-mouth repeat in which a total of three courses (8, 11, 17) including the tack course 3 are repeated in the wale direction, It can be said that the both sides sandwiching the tack course 3 are knitted structures (double knit courses 8 and 17) having no tack.

In the first embodiment, the second double knit course 17 is also knitted with a ground yarn 18 and a splicing yarn 19. In the second double knit course 17 as well, the loop shape formed by the ground yarn 18 and the loop shape formed by the splicing yarn 19 are arranged to closely approach each other when the shape is stabilized after shrinkage.
As a result, in the knitted fabric 1 of the first embodiment of the present invention, the entire knitted fabric has a knitted structure formed by plating. By doing in this way, it has succeeded in relieving the difference in volume feeling between courses and not causing a sense of incongruity visually and wearing.

The knitted fabric 1 of the present invention having such a configuration can be knitted by, for example, a double circular knitting machine (not shown) provided with a cylinder and a dial. In this case, the yarn is run in the circumferential direction (course direction) of the cylinder or the dial, and is knitted down into a cylindrical shape by feeding yarns from a plurality of yarn feeders provided in the course direction.
In the tuck course 3 and the double knit courses 8 and 17, it is preferable that the knitted surface on the cylinder-needle side is formed as the skin side surface of the garment by raising the loop knitted on the cylinder-needle side and raising the fluff.

In order to give the garment a relaxed feeling, the knitting lengths of the ground yarns 4, 12, 18 and the splicing yarns 5, 13, 19 are standard when knitting the tack course 3 and the double knit courses 8, 17. It is preferable that the length of the loop to be formed is increased by setting it to be extended longer than the yarn feeding length at the time of typical double knit knitting.
As a result of producing clothing using the knitted fabric 1 of the present invention having the knitted structure of the first embodiment, a flexible stretch property (extensibility) while producing sufficient volume in the knitted fabric thickness to provide heat retention. We were able to complete clothing that was easy to move.

By the way, in the knitted fabric 1 of the present invention, it is not limited that the knitting structure is a three-piece repeat of the tack course 3 and the double knit courses 8 and 17. For example, as shown in FIG. 3 as a second embodiment, a third double knit course 23 (ground yarn 24 and splicing yarn 25) may be further provided after the second double knit course 17 to form a four-piece repeat. .
Depending on the case, as shown in FIG. 4 as a third embodiment, a two-part repeat of a tack course 3 and a double knit course 8 may be used.

  In the tack course 3, the tack loop 3a may be formed by a cylinder needle (lower needle) or a dial needle (upper needle). Therefore, for example, as shown in FIG. 5 as the fourth embodiment, the tack course 3 and the double knit course 8 in which the tack loop 3a is alternately formed on the cylinder needle side and the dial needle side may be combined. . In this case, the tack course 3 can be provided so as to be a plurality of continuous or non-continuous courses in the wale direction.

  On the other hand, the tuck knitting employed in the tack course 3 can be tucked twice or tucked three times. For example, as shown in FIG. 6 as the fifth embodiment, in the case of the two-time tack, the tack loop 3a is put on the loop 17a of the course 17 adjacent to the tack course 3 with one course in the wale direction. It will be. In the case of three-time tack (not shown), the tack loop 3a is put on the loop of the next course after two courses from the tack course 3.

  Thus, even in the case where a plurality of tacks such as two tacks are performed, in the knitted fabric 1 of the present invention, the course 17 (see FIG. 6) having the loop 17a covered by the tack loop 3a of the tack course 3 is attached to the ground yarn 18. If the knitting structure is knitted with the yarn 19, the [ground yarn 4 and the splicing yarn 5] and the [ground yarn 18 and the splicing yarn 19] are formed by the tack loop 3a and the loop 17a covered by the tack loop 3a. The quadruple loop 27 is formed.

Accordingly, the presence of the quadruple loop 27 enables the knitted fabric 1 of the present invention to generate a volume sufficient for the knitted fabric thickness.
As is clear from this, it is not necessarily limited that the tack loop 3a of the tack course 3 is put on the “loop 8a of the course 8 adjacent to the tack course 3”.

In addition, in this 5th Embodiment, what was comprised as a 4 mouth repeat which has arrange | positioned 3 types of double knit courses 8, 17, and 26 following the tack course 3 is illustrated. Of these, the double knit course 26 is also a knitted structure knitted with a base yarn 28 and a splicing yarn 29.
Also in this case, it can be said that both sides sandwiching the tack course 3 are knitted structures (double knit courses 8 and 26) in which no tack is present, and the entire knitted fabric is a knitted structure plated.

  FIG. 7 shows a sixth embodiment of the knitted fabric 1 of the present invention. In the sixth embodiment, a single knit course 33 knitted by a single knit (flat knitting) is arranged on the course next to the tack course 3. This single knit course 33 is also plated with a base yarn 34 and a splicing yarn 35. Accordingly, the tack loop 3 a of the tack course 3 is pulled up and covered to the loop 33 a of the single knit course 33.

Thus, a quadruple loop composed of [ground yarn 4 and splicing yarn 5] and [ground yarn 34 and splicing yarn 35] is formed by the tack loop 3a and the loop 33a covered by the tack loop 3a. The volume sufficient for the knitted fabric thickness can be generated.
In addition, when employ | adopting the single knit course 33, what is called a yarn crossing part 37 will appear between the loops adjacent in a course direction. Such a yarn spanning portion 37 may be exposed linearly between ribs on the surface side of the knitted fabric when the knitted fabric is stretched in a conventionally known knitted structure, which may lead to the following problems. there were.

That is, when the yarn crossing portion 37 is exposed, the exposed portion is easily caught by contact with other objects during washing or use, including a fingernail of a person who handles the knitted fabric. Was pulled out and frayed), and in severe cases, it was a factor that led to thread cutting. Further, once such snacking or yarn cutting occurs, a run occurs from that point, and there is a risk that the appearance of the knitting ground is extremely conspicuous in appearance.

However, in the knitted fabric 1 of the present invention, since the single knit course 33 is knitted by the plating knitting having the ground yarn 34 and the splicing yarn 35, the yarn crossover portion 37 is doubled and reinforced. become. In addition, the yarn spanning portion 37 is subjected to positional restraint by the above-described quadruple loop, and the looseness is limited.
Therefore, it is possible to prevent the yarn crossover portion 37 from being snacked or cut due to contact with the nails of the person who handles the knitted fabric 1 of the present invention or with other objects during washing or use. In addition, even if the yarn crossing portion 37 is caught, the risk of reaching the snacking is suppressed as much as possible because the yarn crossing portion 37 is reinforced and subjected to positional restraint. .

Of course, if the welded yarn is used for the tack course 3 or the single knit course 33 and the heat setting process is performed on the knitted fabric after knitting, the course 33 having the loop 33a covered by the tack loop 3 and the tack loop 3a of the tack course 3 is used. Are fused or joined together by the welding yarn, so that snacking is surely prevented under such circumstances.
FIG. 8 shows a seventh embodiment of the knitted fabric 1 of the present invention. The seventh embodiment is a further development of the sixth embodiment (see FIG. 7) as a basic pattern. The tack course 3 is also called a tack loop 3a and a welt part (also called a miss part or a floating knitting part). ) A knitting structure in which 3b is mixed alternately is adopted.

  In addition, after repeating the two-mouth repeat of the tack course 3 and the single knit course 33 six times between the first yarn feeder and the sixth yarn feeder, the arrangement of the tack loop 3a and the welt portion 3b of the tack course 3 Is a half-pitch shift in the course direction, and a knitting structure is used in which a two-knit repeat with the single knit course 33 is repeated six times between the 7th yarn feeder and the 12th yarn feeder.

Naturally, the tuck course 3 is subjected to plating with the base yarn 4 and the splicing yarn 5, and the single knit course 33 is also subjected to plating with the base yarn 34 and the splicing yarn 35.
Therefore, also in the seventh embodiment, the tack loop 3a of the tack course 3 is pulled up to the loop 33a of the adjacent single knit course 33 and is covered to generate a portion where a quadruple loop is formed.

  FIG. 9 shows an eighth embodiment of the knitted fabric 1 of the present invention. In the eighth embodiment, a tuck course 3 in which a tuck portion 3 and a welt portion 3b, which are obtained by repeating the tuck loop 3a twice, are knitted alternately is arranged between the first yarn feeder and the third yarn feeder, and the fifth A knitting structure in which a course 40 that repeats only the welt part 3b by the cylinder needle and the welt part 3b by the dial needle is sandwiched between the yarn feeder -7 and the yarn feeder 7 and at the 4th and 8th yarn feeders. It is as.

At least the tack course 3 is plated with a base yarn 4 and a splicing yarn 5 (not shown). Therefore, the tack loop 3a of the tack course 3 is pulled up to the loop of the parallel course and is put on to generate a portion where a quadruple loop is formed.
By the way, the present invention is not limited to the above-described embodiment, and can be appropriately changed according to the embodiment.

For example, the knitted fabric 1 of the present invention can be knitted by a circular knitting machine equipped with a double cylinder or a flat knitting machine with two rows of needle beds. As is clear from this, the knitted fabric 1 according to the present invention is not conditioned to be tubular, or to undergo a form knitted as a tubular shape, but as a single flat knitted fabric. It may be organized.
In each course including the tack course 3, the thread type to be used is not particularly limited. For example, a long fiber is adopted for the tack course 3, or a short fiber is adopted for other courses. Also good. Further, what is specifically selected as the short fiber or the long fiber is not limited at all.

In the tack course 3, the pitch in the course direction in which the tack loop 3a is provided is not limited. However, it goes without saying that the more the tack loops 3a, the more the volume of the knitted fabric is given.
In plating knitting, the number of ground yarns and splicing yarns is not limited to one each. In some cases, a plurality of ground yarns or a plurality of splicing yarns can be used. For this reason, the multiple loop formed by the tack loop 3a of the tack course 3 is not limited to a quadruple loop, and can be implemented in the case of a fivefold loop or a sixfold loop.

  In plating knitting, unless the front side or the inside of the knitted fabric needs to be specified, the arrangement relationship in which the ground yarn and the splicing yarn are close to each other is not particularly important. Therefore, in the present specification, “plating knitting (split knitting)” includes “cross knitting (drawing knitting)”.
