Description

TECHNICAL FIELD The present invention relates to a multi-layered gauze fabric which is soft, resilient, has a smooth feel, and is excellent in stretchability, drainability, and quick-drying properties.

In recent years, due to changes in the living environment accompanying global warming, gauze fabrics have attracted attention due to their advantages such as coolness, lightness, and ease of use. A gauze fabric is generally a plain weave fabric that is coarsely woven with thin yarns using cotton threads, and is made into a double or triple gauze fabric by stacking, for example, 2 to 3 layers of the fabric and tying them together with a connecting thread. . Therefore, since there is an air layer between the woven fabrics compared to the conventional one-piece woven fabric, the woven fabric has a fluffy feel, is highly breathable, lightweight, and has excellent heat retention properties. It is used in a wide range of applications, including gauze towels, sheets, blankets, bedding such as pillow covers, clothing such as gowns, pajamas, shirts, pants and mufflers, and medical gauze.

However, in order to be able to develop not only innerwear and shirts, but also innerwear such as skirts, bottoms, dresses, and dress shirts, as well as outerwear, gauze fabrics with high-quality texture and high functionality have been commercialized. The current situation is that it has not been achieved. Conventional 100% cotton fabrics have a hard feel, lack resilience, and wrinkle easily. In addition, the surface lacks smoothness due to the fuzzy texture. Furthermore, it lacks drapeability (hanging property), so it lacks fluidity and wearing comfort.

On the other hand, in terms of functionality, as is well known, cotton fabrics have poor stretchability. As for stretchability, it is easy to stretch if it is thin, but it has poor recovery when the arms and knees are stretched. is. In addition, if the garment is worn forcibly, the strength of the garment is low, so there is the problem that the sewn parts may fray, the fabric may tear, or the fabric may be damaged by abrasion.

Furthermore, although cotton fabrics are excellent in water absorption, they are slow to dry. This is because the central part of the cotton fiber has a hollow structure called a lumen when washed, and the fiber contains a large amount of water. For this reason, the actual situation is that the water drainability in dehydration is poor, the energy loss due to the hanging drying time and the power consumption of the tumble dryer is large, and the quick drying property is poor.

The following proposals have been made regarding this problem.
A multi-layered gauze has been proposed that maintains breathability and light weight, is pleasant to the touch (soft), and has excellent heat retention (Patent Document 1). In addition, there is a multi-layered gauze fabric that can control the generation of wrinkles depending on the application (Patent Document 2). Furthermore, there is a gauze fabric that has an excellent balance of breathability and heat retention, is opaque, has a good texture and is soft (Patent Document 3). In addition, a multi-layered gauze fabric having excellent frictional strength while maintaining softness to the touch has been proposed (Patent Document 4).

As a technical means for solving this problem, in Patent Document 1, cotton yarn is used, and the twist coefficient of the warp and weft that constitute the surface fabric is softly twisted to 3.0 or less to create a soft texture, while the twist coefficient of the back fabric is set to 3. A hard twist yarn of 0 or more is used. In Patent Document 2, cotton yarn is used, and non-twisted yarn is used for the surface fabric, while hollow twisted yarn is used for the back fabric to control the occurrence of wrinkles. In Patent Document 3, cotton yarn is used, and the warp and weft constituting the surface fabric are loosely twisted with a twist coefficient of 3.0 or less to create a soft texture, while the back fabric uses a hard-twisted yarn with a twist coefficient of 3.0 or more. . In Patent Document 4, cotton yarns are used to change the twist coefficients of the warp and weft yarns of the front and back fabrics, respectively, and high-twist yarns are used to increase the frictional strength without changing the twist coefficients of the warp and weft yarns of the intermediate fabric. .

As described above, the current situation is that none of the patent documents clearly mentions a multi-layered gauze fabric that is soft, resilient, has a smooth texture, and has excellent stretchability, drainability, and quick-drying properties. . The present invention, as a result of intensive studies aimed at maximizing the characteristics of gauze fabrics, found that a multi-layered gauze fabric in which a plurality of thin fabrics are layered and intermittently connected with each other with a connecting thread, the warp and weft of the fabric. By using a multi-layer gauze fabric in which at least one of them is composed of crimped multifilament yarns of synthetic fibers and has an elongation rate of 5% or more and an elongation recovery rate of 50% or more, such texture improvement and We have succeeded in imparting highly elastic and quick-drying functionality.

It is an example of a structural diagram of a double gauze fabric preferably used in this embodiment. It is an example of a structural diagram of a triple gauze fabric preferably used in the present embodiment. 1 is a waveform chart for measuring the surface roughness: SDM of the mean deviation of the surface irregularities of the gauze fabrics of Example 1, Example 2, and Comparative Example 1. FIG.

FIG. 1 is an example of a fabric cross-sectional structure diagram of a double gauze fabric as an example of the multiple gauze fabric used in the present invention. In the figure, A-1 is the surface fabric, a1 is the warp, and b1 is the weft. A-2 is the back fabric, a2 is the warp, b2 is the weft, A-1 and B-2 are overlapped and intermittently connected to each other by the connecting yarn X1. FIG. 2 is an example of a fabric cross-sectional structure diagram of a triple gauze fabric as another example. In the figure, A-1 is the surface fabric, a1 is the warp, b1 is the weft, A-2 is the back fabric, a2 is the warp, b2 is the weft, A-3 is the intermediate fabric, and a3 is the warp. , b3 are weft threads. The fabrics A-1, A-2 and A-3 are overlaid and intermittently connected with each other by connecting threads X1 and X2. In addition, in FIG. 1 and FIG. 2, the distance between the connecting threads is shortened.

The details of this embodiment will be described. The multi-layered gauze fabric of this embodiment is a multi-layered gauze fabric in which a plurality of thin fabrics are layered and intermittently knotted together with a connecting thread. As shown in the figure, if there are two thin fabrics (A-1 and A-2) to be superimposed, it is the double gauze fabric in FIG. If it is -3), it is the triple gauze fabric of FIG. By sequentially adding the intermediate fabrics A-4 and A-5 in this way, a four-layer fabric and a five-layer fabric are obtained, and a multi-layer fabric is obtained. The multi-layered gauze fabric of this embodiment is soft, has resilience, has a smooth texture, and has excellent stretchability, drainability, and quick-drying properties, as well as breathability and light weight. A gauze fabric is preferred, and a double or triple gauze fabric is particularly preferred because it can maximize its lightness and quick-drying characteristics. In addition, for example, the thin fabrics to be stacked may be different fabrics (A-1 ≠ A-2 ≠ A-3) in a triple fabric, but the same fabric (A-1 = A-2 = A-3). Laminated fabrics are preferred because they provide a uniform texture and stretchability.

The connecting yarn is part of the warp or weft of the thin fabric, and is woven while directly or indirectly connecting the fabrics. Although the knotting interval of the connecting yarn is not limited, the knotting interval is 3 to 6 mm in the width direction of the fabric and 6 to 10 mm in the length direction from the balance between the looseness and unity of the fabric. is preferred. Weaving machines include dobby looms, jacquard looms, and towel looms, which are ordinary gauze looms.

In this embodiment, multifilament yarns (long fibers) of synthetic fibers are used for such a woven fabric. Compared to spun yarn (short fiber) of the same synthetic fiber, it has long fibers and no fluff, so it has resilience, smooth texture, elasticity, quick drying, anti-pilling, etc., so it is preferably applied. There are features that can be done. In addition, since the multifilament yarn is much finer than the conventional cotton yarn, it is possible to obtain a thinner fabric, and it is easy to form a multiple weave. In this embodiment, at least one of the warp and the weft of the fabric is a crimped synthetic multifilament yarn. It may be used for both warp and weft.

Synthetic fibers are not limited as long as they are long fibers (filament yarns), but may be polyester, polyamide, polyacrylic, polyurethane fibers, etc., as long as they exhibit elasticity. Among them, polyester-based and polyamide-based multifilament yarns are particularly preferable because of their smooth texture, high stretchability, and excellent quick-drying properties.

Among polyesters, polyethylene terephthalate (hereinafter abbreviated as PET), which is generally used for general purposes, has a wide variety of particularly thin yarns, is easy to make into thin fabrics, and has many raw yarns with high elasticity. Most preferred. As for PET, in addition to the regular type that can be dyed with disperse dyes, there are copolymer PET such as cationic dyeable polyester and easily dyeable polyester. In addition to regular PET, there are polytrimethylene terephthalate (hereinafter abbreviated as PTT) and polybutylene terephthalate (hereinafter abbreviated as PBT) polymers, and latent crimps of composite fibers obtained by laminating such polymers and PET polymers in a bimetallic manner. Threads can also be applied.

Nylon 6, nylon 66, and the like are typical polyamide-based multifilaments, and compared to PET, even thick yarns can provide a soft feel, and can be preferably applied because they have the same stretchability and quick-drying properties. In addition, since it can be dyed under normal pressure with an acid dye, it is easy to dye and has the merit of obtaining a vivid color, which is preferable.

Polyurethane fibers have too high stretchability, but on the other hand, they are always in a shrunk state and have a rough texture, and when stretched, the binding force is too strong. is preferred.

Here, the total fineness and the single fiber fineness of the multifilament yarn (long fibers) will be explained. For example, the display raw yarn of 84T-36F is a raw yarn in which 36 filaments with a total fineness of 84 decitex and a single fiber fineness of 2.3 decitex are aggregated. The smaller the total fineness and the smaller the single fiber fineness, the finer the yarn and the softer the texture.

In this embodiment, the multifilament yarn has a total fineness of 5 to 500 decitex and a single fiber fineness of 0.05 to 10.0 decitex. In particular, the total fineness is preferably 10 to 300 decitex, and the single fiber fineness is preferably 0.2 to 8 decitex, in order to obtain a soft and elastic texture of the fabric. It is selected and used as appropriate depending on the thickness of the woven fabric and its intended use. A fiber with a total fineness of less than 5 decitex and a fiber with a single fiber fineness of less than 0.05 decitex are not preferable because they are too thin and have a rough texture. On the other hand, fibers with a total fineness exceeding 500 decitex and those with a single fiber fineness exceeding 10 decitex are too thick and have a hard texture, which are both undesirable.

(Using threads for textiles)
To give a specific example of the use of yarn for the fabric of this embodiment, gauze fabric equivalent to single yarn No. 30 to No. 50, which is widely used in conventional 100% cotton yarn, has a total fineness of 195 for this multifilament yarn. A yarn of ~117 decitex and a single filament fineness of 0.5 to 5 decitex can be preferably applied. Further, it is preferable to use a yarn having a total fineness of 97 to 49 decitex and a single yarn fineness of 0.3 to 6 decitex for fine yarns equivalent to No. 60 to 120 single yarns. In addition, in this embodiment, a yarn with a total fineness of 32 to 5 decitex and a single yarn fineness of 1 to 2 decitex can be used even for ultrafine yarns equivalent to single yarns of No. 180 to No. 1000, which cannot be handled with cotton yarns. There is a feature.

In the present embodiment, the multifilament crimped yarn is not particularly limited as long as it is a yarn that exhibits a woven fabric elongation of 5% or more and an elongation recovery rate of 50% or more. The elongation percentage of 15 to 60% is particularly preferred because it is excellent in conformability to the body. In addition, those with an elongation recovery rate of 60 to 95% do not cause the above-mentioned defects called "elbow slippage" or "knee slippage", and are less likely to wrinkle and have high stretch back properties, making them comfortable to wear. is particularly preferred. It should be noted that, if the elongation percentage is less than 5% and the elongation recovery rate is less than 50%, the stretchability is poor, which is not preferable.

As the crimped yarn, a textured textured textured textured textured textured textured textured textured textured textured textured textured textured textured textured textured textured textured textured textured textured textured textured textured textured textured textured textured textured false twisted twisted yarn, a textured yarn of a twisted yarn, and a latently crimped yarn are preferable because they exhibit high stretchability while having a soft and smooth texture.

Temporary twisted yarn is specifically a temporary twisted yarn made by twisting PET or nylon 6 yarn at 180 to 220°C, or a Taslan composite textured yarn that combines a temporary twisted yarn in the core and two stretched yarns in the sheath. etc., and can be preferably applied to soft and bulky applications.

The twisted yarn is preferably 140 decitex class yarn twisted at 500 to 2000 turns/m from the balance between stretchability and smooth texture, and is exemplified.

The latently crimped yarn is a bimetallic composite spun yarn of PTT/PET or PBT/PET described above, and develops a spiral crimp. It is suitable for thin fabrics because it has a slightly smaller bulk than temporary twist.

A textured yarn obtained by combining such provisional twisting, provisional twisting composite processing, twisting processing, and latent crimping yarn, respectively, is also preferable. For example, a false-twisted additionally twisted yarn obtained by combining a false-twisted yarn with a twisting process is preferable because the stretchability is synergistically increased.

In the present embodiment, in addition to using 100% of such crimped synthetic multifilament yarn, the filament yarn is made of vegetable staple fibers such as cotton, hemp, rayon and cupra, or long fibers such as rayon and cupra. It is also preferable to use spun and plied yarns or plied and twisted yarns. For example, a composite of crimped yarn in the core and vegetable staple fibers in the sheath is preferably exemplified because it has both vegetable water absorbency and hygroscopicity and stretchability of the core yarn.

Next, in the case of weaving such crimped yarn, this embodiment is a union fabric used for either the warp or the weft of the fabric, and a 100% synthetic fiber fabric used for both the warp and the weft. In the interwoven fabric, the warp is made of vegetable fibers such as cotton, and the weft is made of the crimped yarn. The resulting fabric has a well-balanced combination of the water absorbency and hygroscopicity of vegetable fibers and the smooth texture, stretchability, and quick-drying properties of synthetic fibers. It is a particularly preferred fabric because it can be The mixing ratio of the synthetic crimped yarn is preferably in the range of 20% to 80%.

In addition, although the 100% synthetic fiber fabric used for both warp and weft is poor in water absorption and moisture absorption, it has a softer and smoother texture and improves quick-drying, so it can be used for underwear such as skirts, blouses, and dresses. Apparel applications are preferred.

As the vegetable fiber referred to in the present embodiment, cotton is particularly preferable from the viewpoint of water absorption, hygroscopicity, and handleability. A small amount of hemp, rayon, cupra, or wool may be blended with cotton. A blend of rayon and cupra provides hygroscopicity, while wool retains heat.

(Processing finishing method)
Next, the processing finishing method of this embodiment will be described. For example, in a union fabric of warp cotton yarns and weft polyester crimped yarns, the gray fabric is first processed through cotton scouring (100° C., weak alkaline bath) and bleaching (100° C., hydrogen peroxide bath). At the same time, since the fabric is treated with boiling water during this process, it is confirmed that the width of the fabric shrinks in the weft direction and that crimps are developed. Next, the polyester side is dyed with a disperse dye at 130° C., and the cotton side is dyed with a reactive dye at 80° C., dried, and set with dry heat at 150 to 180° C. to finish.

If the weft of the union fabric is cationic dyeable polyester yarn, it is dyed with a cationic dye, and if the weft is polyamide yarn, it is dyed with an acid dye, and then the cotton side is dyed with a reactive dye for finishing. By properly using cationic dyes and acid dyes, it is possible to obtain products with a variety of dyeing designs, such as the same color as cotton, different shades, and different colors.

The present embodiment will be described in detail below based on examples, but the present embodiment is not necessarily limited to these.
"Measuring method"
1. Evaluation of texture of gauze fabric (1) Evaluation of soft texture Using a pure bending measuring device: KES-FB2 (manufactured by Kato Tech Co., Ltd.), the fabric is bent in the horizontal direction (weft direction) of the fabric, and the average bending of 5 points is measured. Rigidity: B value (gf.cm/cm) was obtained. The smaller the value, the softer the bending and the softer the feel, which is good.

(2) Evaluation of resilience handfeel Using the same measuring instrument as for evaluation of soft handfeel, the fabric was bent in the horizontal direction (weft direction), and the average bending hysteresis of 5 points: 2HB value (1/cm ² ) was obtained. . The smaller the value, the smaller the bending strain, the more repulsive the texture, and the better.

(3) Evaluation of smooth texture Using a surface testing device: KES-FB4-AUTO-A (manufactured by Kato Tech Co., Ltd.), the surface of the fabric in the horizontal direction (weft direction) is traced with a rubbing element, and the average deviation of surface unevenness surface roughness: The SDM value was obtained. Five measurement points were used, and the average value was shown. The smaller the value, the smaller the unevenness of the woven fabric surface, the smoother it is, and the better. FIG. 3 is a waveform chart for measuring the surface roughness (SDM) of the gauze fabrics of Example 1, Example 2, and Comparative Example 1. As shown in FIG. The smaller the unevenness of the corrugation, the smoother and more favorable it is.

2. Evaluation of Elasticity of Gauze Fabric (1) Elongation Percentage Elongation (%) of the fabric in the horizontal direction (weft direction) of the fabric was measured according to JIS L1096 B method B-1 method (constant load method). The sample had a width of 50 mm and a length of 300 mm, and a mark was made at 200 mm to measure elongation under a load of 1.5 kg. The marked portion is the length of the raw cloth, and the elongation rate was obtained by the following formula. Five measurement points were used, and the average value was shown. The larger the value, the better the extensibility, which is good.
Elongation rate (%) = (Length of fabric under load (L1)) - (Length of raw cloth (L0)) / (Length of raw cloth (L0)) × 100

(2) Elongation recovery rate The woven fabric was measured by the same JIS method as the elongation rate. After applying a load in the horizontal direction (weft direction) of the fabric, the load was removed, and the elongation recovery rate (%) after 30 seconds was measured by the following formula. The sample shape, load, and five measurement points are the same as those for elongation measurement. The larger the value, the better the recovery from elongation.
Elongation recovery rate (%) = <(L1-L2) / (L1-L0)> × 100
However, L0 is the length of the original fabric, L1 is the length under load, and L2 is the length after applying the load and unloading.

3. Evaluation of drainability of gauze fabric (1) Residual moisture content The fabric was cut into a constant weight of 12.4 g and precisely weighed (cut size: approximately 30 cm square). Next, the fabric is immersed in water for 20 minutes, then the wet fabric is picked up, centrifuged for 4 minutes in the dehydration tank of the washing machine, weighed accurately, and the residual moisture content (%) of the fabric is calculated by the following formula. rice field. The smaller the value, the better the drainability. The better the drainability, the faster the subsequent drying rate.
Residual moisture content of fabric (%) = (Weight of fabric after immersion in water and dehydration (W1)) - (Weight of fabric before immersion in water (W0)) / (Before immersion in water Weight of fabric (W0)) x 100

4. Evaluation of quick-drying property of gauze fabric (1) Washing and drying time The fabric soaked in the water and dehydrated was suspended in an air-conditioned room to measure the time required for the fabric to dry completely. Drying conditions are temperature 17° C., humidity 50%, wind speed: almost no wind. For the drying time, the weight of the woven fabric was measured every 10 minutes, and for the woven fabric that dried slowly, the weight of the woven fabric was measured every 30 minutes from the middle of drying. The shorter the drying time, the better the quick-drying property.

(Example 1)
(1) Production method and evaluation method of double gauze fabric Weaving Using 1050 turns/m of cotton yarn No. 40 single yarn for warp, polyester multifilament for weft yarn, total fineness 148 decitex (equivalent to cotton yarn No. 40 single yarn), 408 filament, temporary twist of single fiber fineness 0.35 decitex A textured yarn was used, which was further twisted at 800 turns/m to obtain a false-twisted textured yarn. The back fabric A-2, which is the same as the front fabric A-1 in FIG. A knotted double gauze fabric was woven on a dobby loom. The connecting yarns were warp yarns, which were intermittently knotted at intervals of 8 mm in the length direction and at intervals of 6 mm in the width direction. The blend ratio of the fabric material is 42% polyester and 58% cotton.

B. Finishing processing Using a liquid jet dyeing machine, the woven raw fabric is subjected to cotton scouring (100°C, weak alkaline bath) and bleaching process (100°C, hydrogen peroxide bath). It was confirmed that the fabric was shrunk and crimped in the weft direction (35.4% shrinkage at a width of 115 cm). Next, the polyester side was dyed with a navy blue disperse dye at 130° C. for 40 minutes, and the cotton side was dyed with a navy blue reactive dye at 80° C. for 30 minutes and dried. Subsequently, it was finish-set with a width of 121 cm by dry heat at 150°C. The finished width was 121 cm, the length was 48.8 m, the warp density was 154 threads/inch, and the weft density was 86 threads/inch. Table 1 shows the evaluation results of the finished fabric.

(Example 2)
The weft yarn was woven and dyed in the same manner as in Example 1, except that the weft yarn was not twisted after tacking and only the tacking yarn was used. The finished width was 139 cm, the length was 48.8 m, the warp density was 130 threads/inch, and the weft density was 86 threads/inch. Table 1 also shows the evaluation results of the finished fabric.

(Comparative example 1)
A 100% cotton double gauze fabric was woven by using the same twisted yarn of No. 40 cotton yarn as in Example 1 for the warp and twisting the No. 40 cotton yarn for the weft at 800 turns/m. The dyeing was finished according to Example 1, except that the dyeing was done with a navy blue reactive dye at 80° C. for only 30 minutes. The finished width was 158 cm, the length was 48.8 m, the warp density was 115 threads/inch, and the weft density was 86 threads/inch. Table 1 also shows the evaluation results of the finished fabric.

(2) Evaluation results

(3) Evaluation result A. Example 1
As is clear from Table 1, the woven fabric of Example 1 is a wonderful dark blue double gauze woven fabric that is soft, has resilience, has a smooth texture, and is excellent in elongation, elongation recovery, drainability, and quick drying. there were. Specifically, the softness was 2.2 times, the resilience was 1.2 times, and the smoothness was 1.8 times the 100% cotton fabric of Comparative Example 1. The elongation rate was 39.8% and the elongation recovery rate was as high as 82.0%. In addition, the drainability was 1.5 times better than that of Comparative Example 1, and the drying time was 70 minutes, which was 7.5 times faster than that of Comparative Example 1. As for the water absorption speed, when one drop of water was dropped from a height of 10 cm using a dropper at hand, the water was absorbed in 7 seconds, confirming the water absorption. It should be noted that both weaving and dyeing could be carried out smoothly without any trouble. The finished gauze fabric was sewn into a blouse and a practical test was conducted. The texture was light, soft and smooth, and had good conformability to the body. In addition, the water drainability in washing was good, and it was possible to dry quickly.

B. Example 2
As shown in Table 1, almost the same as the fabric of Example 1, the double gauze fabric was excellent in texture, stretchability, drainability and quick-drying properties. In detail, the elongation rate and stretch recovery are slightly lower than those in Example 1, probably because the weft is only a false twist and is not twisted, but the smoothness of the surface, drainability, and quick drying are excellent. Met. As a result of evaluation according to Example 1, the water absorption speed was 6 seconds, and it was confirmed that there was water absorption.

C. Comparative example 1
As shown in Table 1, Comparative Example 1 (100% cotton) was harder to the touch than Examples 1 and 2, had no resilience, and had a rough texture. Also, although the elongation rate was achieved, the elongation recovery was 35.2%, and the stretchability was unattained. In addition, it was an ordinary dark blue double-layered gauze fabric with poor drainage and especially quick drying properties. In addition, the water absorption rate was 5 seconds, indicating that it had water absorption.

(Example 3)
(1) Production method and evaluation method of double gauze fabric The weft is a bimetallic latent crimp-exhibiting yarn with a circular cross section, in which polyester multifilament PTT/PET polymers are laminated in a crescent shape, with a total fineness of 168 decitex. (equivalent to a 31.6 single cotton yarn), 72 filaments, and a single fiber fineness of 2.3 decitex were used, but in accordance with Example 1, the warp cotton and the weft yarn were interwoven and doubled on a dobby loom. Woven into a gauze fabric. The woven fabric has a warp density of 100 lines/inch, a weft density of 84 lines/inch, a width of 178 cm, and a length of 50 m. The blend ratio of the fabric material is 43% polyester and 57% cotton.

The finished width was 142 cm, the length was 48.8 m, the warp density was 118 lines/inch, the weft density was 86 lines/inch, and it was a polyester, pink-dyed double gauze fabric.

The evaluation results of the finished woven fabric are slightly lower than the woven fabric of Example 1, but it is soft, has resilience, has a smooth texture, elongation rate (18.4%), and elongation recovery rate (86.2%). It was drainable (residual moisture content: 57.2%) and quick-drying (drying time: 70 minutes). It was a double-layered gauze fabric dyed in the same pink color as cotton, with excellent texture and high functionality.

(Example 4)
(1) Production method and evaluation of triple gauze fabric Using 1200 turns / m of cotton yarn No. 60 single yarn for warp, polyamide nylon 66 total fineness 110 decitex (equivalent to cotton yarn No. 48 single yarn) for weft, 96 filaments A false-twisted yarn having a single fiber fineness of 1.15 decitex was used, which was further twisted at 600 turns/m to obtain a false-twisted yarn. The warp density is 105 lines/inch, the weft density is 82 lines/inch, the width is 170 cm, and the length is 50 m. A triple gauze fabric intermittently knotted with a connecting thread was woven on a dobby loom. The connecting yarns were warp yarns, which were intermittently knotted at intervals of 6 mm in the length direction and at intervals of 4 mm in the width direction. The blend ratio of the fabric material is 33% nylon and 67% cotton.

This gray fabric was scoured and bleached in the same manner as in Example 1. The nylon side was then dyed with a black metallized acid dye at 120°C and the cotton side was dyed with a yellow reactive dye at 80°C in two baths. It was then finished according to Example 1. The finished width was 129 cm, the length was 48.8 m, the warp density was 130 lines/inch, and the weft density was 84 lines/inch.
