Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to elastic knitted fabrics and processed products of elastic knitted fabrics. The present invention relates to a so-called elastic knitted fabric, which is knitted using elastic yarns, for a cloth, a cover, and the like, and an elastic knitted fabric product manufactured using such an elastic knitted fabric.

[0002]

2. Description of the Related Art Conventionally, sports gloves used for golf, baseball and the like are often made of heat-retaining cowhide or synthetic leather which is water repellent. In addition, some work gloves have dot-shaped rubber material applied and adhered (dot processing) to enhance the grip, and there are thin rubber gloves for cooking and surgery. A rubber member called a "grip" is attached to a grip portion of a golf club, a bat, a tennis racket, or a tape is wound around the grip portion. Appropriate anti-slip functions and shock absorbing functions are required for the materials used according to each application.

On the other hand, the supporter, or the rubber band of the sock or warmer is provided with a knitted portion of elastic yarn at a part thereof so as to prevent the contacting skin from slipping. For this purpose, a knitted or knitted fabric of elastic yarn and synthetic yarn or spun yarn of natural fiber is used.

[0004]

However, among the sports gloves described above, the one using cowhide has a problem that when it gets wet with rain, its gripping power is suddenly reduced and play is hindered. In outdoor sports such as golf and baseball,
You may have to play in the rain,
Improvement is required. There is also a problem that so-called "sweat stain" occurs due to long-term use and perspiration, and the grip becomes uncomfortable. The synthetic leather treated with water repellency has a problem of stuffiness because it has no sweat absorption property, and the anti-slip effect is not sufficient. In addition, since the one using a rubber material has hardness, it does not feel moist to the sensation of the hand or the grip, and there is a drawback that the feeling of discomfort increases when it is used for a long time.

[0005] Such a problem has also been a problem in grips of various exercise equipment, work gloves and other gloves. Furthermore, since rubber threads and elastic threads are only partially woven in the supporters and socks, there is a difference in thickness from the interwoven fabric, and the feeling of tight binding is strong.
On the skin in contact, evidence of poor circulation (so-called "red mark") was generated, and sometimes eczema was generated.

Of the textures of the knitted knitted fabric, the warp knitted fabric is easy to obtain the reversible of the surface made of the elastic yarn and the back surface made of the knitted yarn, but when the tricot machine is used as the knitting device, 2
Since it is an interwoven knitted fabric composed of fine yarns of 8 gauge or more, the elastic yarn is 70 denier or less and the interlaced yarn is 110 denier or less, fluffing occurs even if there is a surface friction force. It has the drawback of being easy to tear and easy to tear. When a Russell machine is used as a knitting device, the gauge is 56 gauge or less, which is coarser than that of a tricot machine, and both the elastic yarn and the knitting yarn are 70 denier or more, and the spun yarn is used as the knitting yarn. However, since the elastic yarn is used as an insertion yarn that does not form loop stitches, it is difficult to stretch in the weft direction.

[0007] In the case of a weft knitted fabric, it is difficult to obtain reversible front and back, even if it is obtained, the elastic yarn does not clearly form the surface and the anti-slip effect is small. Concerning the stretching direction, the warp direction is insufficient, as opposed to the warp knitted fabric. Therefore, an object of the present invention is to solve the drawbacks of various conventional materials used for exerting an anti-slip function or a shock absorbing function in various applications as described above, and not only for sports but also for various lifestyles. When used as a material for materials, it exerts an appropriate frictional force and can exert a good anti-slip action, and is also highly durable and breathable, and also has an appropriate stretch balance in both vertical and horizontal directions. An object of the present invention is to provide an elastic knitted fabric which has a good motion followability that absorbs and relaxes an impact. Further, by using the elastic knitted fabric as described above, a processed product which can be inexpensively and disposablely replaced as a spare is provided.

[0008]

In the elastic knitted fabric according to the present invention for solving the above-mentioned problems, loop stitches are formed by two or more elastic yarns on the same stitch. As an elastic thread,
The elastic yarn used for a usual elastic knitted fabric can be used, and for example, polyurethane elastic yarn, polyester elastic yarn, polyamide elastic yarn, etc. are used. Among them, polyurethane elastic yarn (spandex) is preferable.

The thickness of the elastic yarn is preferably as thick as possible. Generally, the total sum of the thicknesses of a plurality of elastic yarns forming the loop stitch with the same stitch, that is, the total denier is preferably 140 denier or more, and 280 to 280
A range of 1120 denier is more preferred. The thickness of each elastic yarn, that is, the single yarn denier is preferably in the range of 7.5 to 30 denier, and particularly preferably 10 to 20 denier. In the case of a thin yarn having a single yarn denier of less than 7.5 denier, fluffing occurs in the warping step before knitting, or when various products using an elastic knitted fabric are used, they tend to break.
It is inferior in practicality. If the single yarn denier exceeds 30 denier, the knitting property will be poor, and when processed into various products, the physical irritation during wearing will be too strong, causing skin disorders, or stiff and uncomfortable feeling. It is easy to cause defects.

Further, regarding the cross-sectional shape of the elastic yarn, it is preferable that the arrangement of the multifilament yarns constituting the elastic yarn is relatively close to an ellipse because the frictional force is improved. When two or more elastic yarns are combined, a coated elastic yarn can be used as at least one of the elastic yarns. As the coated elastic yarn, an ordinary coated elastic yarn can be freely used, but for example, a polyurethane processed yarn having a polyurethane elastic yarn as a core and a non-elastic fiber as a sheath is used. In this case, it is preferable to use a polyurethane elastic yarn having a denier of 70 to 560. As the inelastic fiber, it is preferable to use synthetic fiber filament yarn or crimped yarn of 10 to 250 denier polyamide or polyester. The covering of the non-elastic fiber to the core of the polyurethane processed yarn may be single or double. As another polyurethane elastic yarn other than the above, a so-called core spun yarn in which a polyurethane elastic yarn is used as a core and a non-elastic fiber such as cotton or acrylic short fiber is used as a sheath can be used. In this core spun yarn, it is preferable to use a polyurethane elastic yarn having a denier of 70 to 140. As the non-elastic fiber, it is preferable to use a spinning count of cotton count of 4 to 60 s (metric count of 1 / 6.8 to 1/100).

The coated elastic yarn as described above is knitted into loop stitches of the elastic knitted fabric and is used to form one of the front and back sides of the elastic knitted fabric. Most of the coated elastic yarns are preferably used on the back surface side. The elastic knitted fabric of the present invention is knitted by using various elastic yarns or non-elastic yarns in addition to the above-mentioned various elastic yarns and various knitting structures utilized for ordinary elastic knitted fabrics. The specific knitting structure can be set variously depending on the intended use and the required performance. However, in the present invention, a knitting structure in which a loop stitch is formed by two or more elastic yarns in the same stitch is adopted.

The elastic knitted fabric obtained preferably has an elongation of 150% or less in both the wale direction and the course direction. In order to reduce the elongation of the elastic knitted fabric relatively, it is preferable to use a relatively thick yarn as the elastic yarn. Specifically, when the above-mentioned polyurethane elastic yarn is used as the elastic yarn, the elongation rate becomes lower as it becomes 280 denier or even 480 denier than that of the medium-thin yarn of 70 denier. Instead, the power is increased. Also,
If the coated elastic yarn is used instead of the polyurethane elastic yarn, the elongation rate becomes low. In particular, the elongation rate is further reduced in the core span yarn using spun yarn instead of covering yarn.

The elongation rate also changes depending on the knitting structure. For example, in the case of a warp knitted fabric, as the weft swing of the sinker loop is increased by 2 jumps or 3 jumps, the elongation rate decreases.
In other words, it is 1/1 tricot swing, and 2 more than chain knitting.
The / 1/3/1 tricot swing increases the size of the non-stitch sinker loop, resulting in a lower elongation rate. In this case, as a matter of course, the elongation rate of the elastic knitted fabric in the course direction (transverse direction) becomes low. Therefore, in order to balance the elongation in the wale direction (longitudinal direction) and the course direction (horizontal direction), it is preferable to use an inelastic fiber insertion yarn. In the case of a weft knitted fabric, the elongation rate becomes lower as the sinker loop is made longer at the welt position or the tuck position than at the knit position, as in the above case.

As the knitting device for knitting the elastic knitted fabric, various ordinary knitting devices can be used, but it is preferable to use, for example, a warp knitting Russell knitting machine having two or more reeds. in this case,
For both front reed (L-1) and back reed (L-2),
Ordinary elastic yarns that are not coated elastic yarns, that is, bare elastic yarns, are arranged, and knitted with a knitting structure such as double atlas, denbi, reverse half, quins coat, etc. can get.

In the above device, the front reed (L-1)
Even if the bare elastic yarn is arranged on the back reed (L-2) and the coated elastic yarn covered with the soluble fiber or another fiber is arranged on the back reed (L-2), almost the same elastic knitted fabric is obtained. In the case of coated elastic yarn using soluble fiber, this soluble fiber can be eluted by hot water or chemical treatment, and the elastic knitted fabric finally obtained is an elastic yarn obtained from bare elastic yarns. It is possible to obtain the same thing as the knitted fabric. In the case of a coated elastic yarn using a fiber that is not a soluble fiber, the characteristics of the back surface can be changed by a sinker loop depending on the type of fiber used, and a so-called reversible effect can be obtained.

A weft knitting single circular knitting machine can also be used as the knitting device. In this case, a sinker pile circular knitting machine is preferred. The elastic knitted fabric of the present invention can be obtained by arranging bare elastic yarns as pile yarns, covering elastic yarns and the like as ground yarns, and knitting sinker pile knitting. In addition to the above, a double knit circular knitting machine can also be used. In the present invention, as the warp knitting runner ratio of the same needle knitting of the bare elastic yarns, the same idea as in the case of a normal tricot using synthetic fibers may be applied.

In the case of inter-knitting of bare elastic yarn and coated elastic yarn, the warp knitting runner ratio is usually 0.1 ≦ coated elastic yarn runner / bear elastic yarn runner ≦ 0.4, although it depends on the knitting structure. It is preferable to set it. If this runner ratio exceeds 0.4, the stitches of the covered elastic yarn become loose and the stitches become dirty. If the runner ratio is less than 0.1, knitting becomes impossible. A more preferable runner ratio is 0.15 to 0.35.

In the case of weft-knit sinker pile knitting, the covered elastic yarn loop length / the bare elastic yarn loop length is 0.25 to 0.
It is preferable to set it within the range of 4. The elastic knitted fabric knitted as described above is subjected to ordinary processing steps such as relaxation-scouring-dyeing-drying-finishing set dyeing step and the like to produce products used for various purposes. In the case of a bear elastic knitted fabric, the dyeing step can be omitted altogether. In the case of an elastic knitted fabric with a mixed elastic yarn knitting, the process differs depending on the purpose of use such as performing an elution process or dyeing the base fabric (back yarn), but the processing conditions in each process are usually This can be performed under the same conditions as the manufacturing process of the elastic yarn mixed knitted fabric.

The elastic knitted fabric thus obtained can be used as it is for various purposes, but an adhesive layer or a pressure-sensitive adhesive layer can be provided on the back surface of the elastic knitted fabric. When forming an adhesive layer or a pressure-sensitive adhesive layer, it is possible to form it uniformly over the entire surface of the elastic knitted fabric, but when applying an adhesive or the like, the adhesive does not stretch the elastic knitted fabric. It is preferable to attach them intermittently so as not to interfere.
Specifically, various methods used for processing an ordinary adhesive interlining material can be applied, and for example, dot printing processing or spraying method can be adopted. As a device to which such a method is applied, a device similar to a normal bonding interlining processing device is used. The heat-adhesive resin used is preferably a polyamide-based resin, and nylon / epoxy-based or fatty acid-type polyamide is used. Further, as the hot melt adhesive, polyurethane resin, vinyl acetate resin and the like are preferable.

The elastic knitted fabric, whose back surface is dot-processed or sinter-processed (spray method) with the above-mentioned thermo-adhesive resin, is used after being cut into a cloth or a narrow tape having an arbitrary size. . As a method of forming an adhesive layer or a pressure-sensitive adhesive layer on an elastic knitted fabric, in addition to the dot processing and the sintering processing described above, for example, a heat-bondable net-like film or a perforated fill, a non-woven fabric, etc. may be bonded by other means. Alternatively, a method of temporarily adhering to the back surface of the elastic knitted fabric can be adopted.

It is also possible to form an adhesive layer on the elastic knitted fabric and use it as a cloth adhesive tape processed product. For adhesives,
There is no particular limitation, and natural rubber-based adhesives, hot-melt adhesives, vinyl ether-based and acrylic polymer-based adhesives can be used. As a method of forming the pressure-sensitive adhesive layer, a method of applying and drying in the form of an organic solvent solution or emulsion can be applied. If a silicone-based or other release agent layer is formed on one side of the elastic knitted fabric that does not form the pressure-sensitive adhesive layer, the elastic knitted fabric may be layered or wound in a roll shape. It will be possible.

Further, as a processed product of an elastic knitted fabric, for example, in the case of tailoring it into sports gloves, after cutting two front and back sheets according to the pattern of fingers, the contour of the cut cloth is continuously sewn. The heat-adhesive resin is applied in a circular shape, and the two cutting cloths are heat-bonded to each other using an iron or a press machine to complete a sports glove. The sports gloves may be worn on bare hands, or may be layered on leather gloves and used as outer gloves. In the same way, you can use it by molding it according to the shape of your foot and pasting it with a heat-adhesive resin so that you can wear it on your bare feet as socks or layer it on ordinary socks or stockings. it can. In addition, it can also be used for table tennis racket covers and various caps.

In addition, by utilizing the characteristics and functions of the elastic knitted fabric of the present invention, various processes and contrivances can be added to be utilized for various purposes. For example, it can be made into a supporter. In this case, the covered elastic yarn interwoven knitted elastic knitted fabric is more preferable than the one using bare elastic yarn in that the heat retention property can be enhanced.

In the present invention, the method for measuring the stretch ratio of the elastic knitted fabric in the wale direction and the course direction is 2 for a sample of width 5 cm × length 20 cm obtained from each knitted fabric.
The elongation percentage is expressed as% of the original length L ₀ of the length L ₁ after applying a load of kg for 2 minutes. That is, it is calculated by the following formula. Stretch rate% = {(length L ₁ after applying load / original length L ₀ )
-1} x 100

[0025]

The features of the elastic knitted fabric according to the present invention will be described for each characteristic. [Surface friction force] In an elastic knitted fabric product, when a gripping action is exerted, in addition to the elastic yarn constituting the surface (for example, L-1), the elastic yarn constituting the inner layer (for example, L-1) , L-2) are compressed and frictional forces are exerted on each other to increase the grip, so that the so-called “grip” is firm.

On the other hand, in the conventional product in which the elastic knitted fabric is composed of only one elastic yarn, the action of one layer of the elastic yarn causes the force of friction with other non-elastic yarns. You can only get a low price. [Durability] When the elastic yarn is repeatedly used, the elastic yarn cannot withstand the weakening direction when the stretching action in the vertical and horizontal directions or any direction acts. However, in the case of the present invention in which two elastic yarns are used, both elastic yarns can compensate for the balance in the vertical and horizontal directions, and the number of durable uses can be increased. Even if one (surface) elastic thread is weakened, the other (inner layer) elastic thread
It is possible to take over the subsequent weakening, and the durability may be improved. [Breathability] When the elastic knitted fabric is worn and used, the product is in a slightly stretched state and the stitch interval is widened. Sweat absorption of the elastic thread itself,
Since it has almost no hygroscopicity, the elastic yarn does not swell and block the stitches, and the breathability can be improved by expanding the stitches as described above.

On the other hand, in the conventional product using one elastic yarn, the non-elastic yarn is interwoven. The non-elastic yarn has a higher hygroscopicity than the elastic yarn regardless of whether it is a natural fiber or a synthetic fiber, and may swell when it absorbs moisture. Further, if the apparent thickness is large or the yarn is a textured yarn or a spun yarn having fluff, the stitches are naturally blocked and the so-called covering effect is large, resulting in poor air permeability. [Stretch balance] If two or more elastic yarns are knitted fabrics arranged on the front and back sides or the front reed (L-1) and the back reed (L-2), the two movements are symmetrically arranged. Therefore, by forming the elastic yarn having the same stretchability, the left-right balance and the stretch balance in the vertical and horizontal directions are likely to be uniform.

On the other hand, in the conventional knitting structure composed of non-elastic yarns and elastic yarns, which are different materials, the stretch balance of the two yarns is different, and therefore the stretch balance cannot be achieved and the cut end is not formed. It was easy for differences in curl and stretchability in the ears and ears. [Movement followability] As described above, due to its excellent surface friction force and stretch balance, when it is worn and used, it exerts a remarkable "grip" effect when a dynamic action is exerted, or it has a shock absorbing action. I will show you. That is, due to the entanglement (or thickness) of the two elastic yarns, the movement followability is also excellent.

[Table 4] As can be seen from the above-mentioned test results, the characteristics of the examples of the present invention are all friction characteristics (coefficients, coefficients) in comparison with the corresponding comparative examples using non-elastic yarns instead of elastic yarns under the same conditions. Resistance) is high. Regarding the stretchability, it is a low value in both the vertical and horizontal directions, and
Well balanced. The low stretchability enhances the above-mentioned "grip" effect and the function of absorbing and relaxing a momentary impact. On the other hand, in a comparative example with high stretchability, before the frictional force acts during use,
The thread itself of the elastic knitted fabric stretches and the position cannot be fixed,
The anti-slip effect is small. Regarding abrasion resistance, most of the examples show orders of magnitude higher characteristics than the comparative examples, and even the lowest example, Example 4, shows a characteristic almost double that of the comparative examples. In particular, it can be seen that when the Perkren is wet, a large drop is observed in the comparative example, while the characteristics are not significantly deteriorated in the example, and it has excellent performance.

Next, using the elastic knitted fabrics obtained in the above Examples and Comparative Examples, concrete processed products or products were produced. -Examples 7 and 8 and Comparative Examples 6 and 7-The elastic knitted fabrics of Examples 1 and 2 and Comparative Examples 2 and 3 were used.
Using a dot printing device, apply a polyamide adhesive resin consisting of a mixture of epoxy resin 6: polyamide resin 4 to the back surface of each elastic knitted fabric under the conditions of 15 points / inch and a resin amount of 20 g / m ² relative to the fabric weight. did.

The obtained elastic knitted fabric product with the adhesive layer was cut into a tape having a width of 25 mm to manufacture a grip band 20 shown in FIG. This grip band 20,
When it was wound around a grip of a tennis racket, a baseball bat, or other sports equipment and used, it was confirmed to have excellent properties such as showing a good anti-slip effect.

-Examples 9 and 10-Using the elastic knitted fabrics of Examples 1 and 2, fingerless gloves 30 shown in FIG. 5 were manufactured. Wrist part 31, Palm part 32 and Finger part 3
The elastic knitted fabric cut into a predetermined shape corresponding to No. 3 was joined with an adhesive at the seam allowance 35 shown by the dotted line. The composition of the adhesive was as follows.

[0050] The adhesive having the above composition was applied at a rate of 7 g / m ² and adhered by hot pressing.

When the obtained fingerless gloves 30 were used for various works, excellent use performance could be exhibited. -Examples 11 and 12-Using the elastic knitted fabrics of Examples 2 and 3, a sports ankle cover 40 shown in Fig. 6 was manufactured. In the same manner as in Examples 9 and 10, the elastic knitted fabric was cut into a predetermined shape bent from the toe portion 42 to the leg portion 41 and then bonded with an adhesive to obtain a tubular ankle cover. The composition of the adhesive at this time was as follows.

[0052] The adhesive having the above composition was applied at a rate of 10 g / m ² and bonded by hot pressing.

When the obtained ankle cover 40 was used for various works, excellent use performance could be exhibited. -Examples 13 and 14-The elastic knitted fabrics of Examples 4 and 5 were used. On one side of the elastic knitted fabric,
A low-density polyethylene resin was melt-coated to a thickness of 55 μm to form a polyethylene film layer. Next, on the surface of the polyethylene film layer, chromium complex salt (Kiron C)
The addition to 25 mg / m ² coating on the surface of the elastic knitted fabric side, and applying an adhesive to a main agent of natural rubber with a thickness of 280 g / m ^2. This was cut into a width of 50 mm and wound into the same tape shape as in FIG. 4 to manufacture a cloth adhesive band tape. This cloth adhesive band tape has also been found to be useful in various sports applications.

As described above, since the elastic knitted fabric according to the present invention forms a loop stitch with two or more elastic yarns in the same stitch, one loop stitch is made to have a relatively thick elastic thread. Since the knitted fabric is composed of yarns, the knitted fabric is elastic knitted fabric with rich flesh on both sides, and elastic yarns can be arranged on both sides. As a result, when worn,
It has good adhesion to the hands and feet and feels good on the skin, and can exhibit a non-slip effect on both sides.

When two or more elastic yarns are knitted with the covered elastic yarns, a yarn having a high heat retaining property can be obtained and an elastic knitted fabric having an excellent burst strength can be obtained. The processed product using the elastic knitted fabric according to the present invention has good impact absorption when used as a cover cloth or a cover, has a small decrease in surface friction force even in a wet state, and has excellent durability. There is. In addition, the characteristics do not deteriorate even after repeated wearing and washing,
It is possible to provide highly compatible products.
