Description

The present invention relates to a multi-layer gauze woven fabric that is soft, repulsive, has a smooth texture, and is excellent in elasticity, drainage, and quick-drying.

In recent years, gauze fabrics have been attracting attention because of their advantages such as coolness, lightness, and ease of use due to changes in the living environment due to global warming. A gauze woven fabric is generally a plain weave woven fabric that is roughly woven with fine threads using cotton threads, and is made as a double to triple gauze woven fabric by stacking the woven fabrics, for example, two or three sheets and connecting them with a connecting thread. .. Therefore, since there is an air layer between the woven fabrics as compared with the conventional single woven fabric, a characteristic woven fabric having a fluffy texture and rich in breathability, light weight, and heat retention can be obtained. It is widely used for bedding such as gauze towels, sheets, blankets and pillowcases, clothing such as gowns, pajamas, shirts, pants and mufflers, and medical gauze.

However, in order to enable a wide range of clothing from innerwear to outerwear such as skirts, bottoms, dresses, and dress shirts, as well as innerwear and shirts, we have commercialized gauze fabrics with high-quality texture and high functionality. The current situation is that it has not reached. In terms of texture, conventional 100% cotton woven fabrics are hard, have no repulsion, and are prone to wrinkles. In addition, it lacks smoothness due to the fluffy texture on the surface. Furthermore, since it does not drape (hang down), it lacks fluidity and comfort.

On the other hand, in terms of functionality, cotton fabrics have poor elasticity as is well known. Regarding extensibility, it is easy to stretch in the case of thin fabrics, but the recovery is poor when the arms and knees are stretched, and there are drawbacks called "elbow pulling out" and "knee pulling out" in the fully stretched state, which is extremely unsatisfactory. Is. In addition, since the strength is low when the fabric is forcibly worn, there is a problem that the sewn portion is frayed, the fabric is torn, and the fabric is worn, which damages the woven fabric.

Furthermore, while cotton fabric has excellent water absorption, it dries slowly. When washed, the central part of the cotton fiber may have a hollow structure called a lumen, and the fiber contains a large amount of water. For this reason, the drainage property in dehydration is poor, the energy loss of the drying hanging time and the power consumption of the tumble dryer is large, and there is a problem that the quick-drying property is poor.

The following proposals have been made regarding this issue.
A multi-layer gauze that maintains breathability and light weight, is soft to the touch (soft), and has excellent heat retention has been proposed (Patent Document 1). In addition, there is a multi-layer gauze woven fabric that can control the occurrence of wrinkles according to the application (Patent Document 2). Furthermore, there is a gauze woven fabric that has an excellent balance of breathability and heat retention, is transparent, is soft to the touch, and is soft (Patent Document 3). Further, multiple gauze woven fabrics having excellent frictional strength while maintaining softness to the touch have been proposed (Patent Document 4).

As a technical means for solving this problem, in Patent Document 1, cotton yarn is used to make the twist coefficient of the warp and weft yarns constituting the front woven fabric soft with a sweet twist of 3.0 or less, while the twist coefficient of the back woven fabric is 3. Use strong twisted yarn of .0 or more. In Patent Document 2, cotton yarn is used, non-twisted yarn is used for the front surface fabric, and hollow twisted yarn is used for the back surface fabric to control the occurrence of wrinkles. In Patent Document 3, cotton yarn is used to soften the warp and weft yarns constituting the front surface fabric with a sweet twist of 3.0 or less, while a strong twist yarn having a twist coefficient of 3.0 or more is used for the back surface fabric. .. In Patent Document 4, cotton yarn is used to change the twisting coefficients of the warp and weft of the front and back woven fabrics, respectively, and the frictional strength is increased by using the strong twisting yarn without changing the twisting coefficients of the warp and weft of the intermediate woven fabric. ..

As described above, there is currently no document that specifies a multi-layer gauze fabric that is soft, repulsive, has a smooth texture, and has excellent elasticity, drainage, and quick-drying properties in any of the patent documents. .. As a result of diligent studies to make the best use of the characteristics of the gauze woven fabric, the present invention is a multi-layer gauze woven fabric in which a plurality of thin fabrics are stacked and intermittently connected to each other by a connecting thread. By using a multi-gauze woven fabric in which at least one of them is composed of crimp-developed synthetic multifilament yarns and the woven fabric has an elongation rate of 5% or more and an elongation recovery rate of 50% or more, the texture can be improved. It has succeeded in imparting high functionality with high elasticity and quick-drying property.

This is an example of a structural drawing of a double gauze woven fabric preferably used in this embodiment. This is an example of a structural drawing of a triple gauze woven fabric preferably used in this embodiment. It is a waveform chart which measured the surface roughness: SDM of the average deviation of the surface unevenness of the surface unevenness of the gauze woven fabric of Example 1, Example 2, and Comparative Example 1.

FIG. 1 is an example of a woven fabric cross-sectional structure diagram of a double gauze woven fabric as an example of the multiple gauze woven fabric used in the present invention. In the figure, A-1 is a surface woven fabric, a1 is a warp, and b1 is a weft. A-2 is a back surface woven fabric, a2 is a warp yarn, b2 is a weft yarn, A-1 and B-2 are overlapped, and are intermittently connected to each other by a connecting yarn X1. FIG. 2 is an example of a woven cross-sectional structure diagram of a triple gauze woven fabric as another example. In the figure, A-1 is a front woven fabric, a1 is a warp, b1 is a weft, A-2 is a back woven fabric, a2 is a warp, b2 is a weft, A-3 is an intermediate woven fabric, and a3 is a warp. , B3 are weft threads. The woven fabrics A-1, A-2, and A-3 are stacked and intermittently connected to each other by connecting threads X1 and X2. In addition, in FIG. 1 and FIG. 2, the interval between the connecting threads is shortened.

The details of this embodiment will be described. The multiple gauze woven fabric of the present embodiment is a multiple gauze woven fabric in which a plurality of thin fabrics are stacked and intermittently connected to each other with a connecting thread. As shown in the figure, if the number of thin fabrics to be overlapped is two (A-1 and A-2), it is the double gauze fabric of FIG. In case of -3), it is the triple gauze woven fabric of FIG. By sequentially adding the intermediate woven fabrics A-4 and A-5 in this way, quadruple woven fabrics and quintuple woven fabrics are obtained, and multiple woven fabrics can be obtained. The multi-layer gauze woven fabric of the present embodiment is soft, repulsive, has a smooth texture, has excellent elasticity, drainage, and quick-drying properties, and also has breathability and light weight. Therefore, it is double to quintuple. A gauze woven fabric is preferable, and a double to triple gauze woven fabric is particularly preferable because it can maximize the characteristics of light weight and quick-drying property. The layered thin woven fabric may be, for example, a separate woven fabric (A-1 ≠ A-2 ≠ A-3) in a triple woven fabric, but the same woven fabric (A-1 = A-2 = A-3). The superposed one is preferable because a uniform texture and elasticity can be obtained.

Further, the connecting yarn is a part of the warp or weft of the thin woven fabric that is piled up, and is woven while directly or indirectly connecting the fabrics. The binding interval of the connecting threads is not limited, but due to the balance between the looseness and integrity of the woven fabric, the woven fabric is connected at an interval of 3 to 6 mm in the width direction and at an interval of 6 to 10 mm in the length direction. Is preferable. There are dobby looms, jacquard looms, towel looms, etc., which are ordinary gauze looms, and weaving is selected according to the application.

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

The synthetic fiber is not limited as long as it is a long fiber (filament yarn), but it may be a yarn that expands and contracts, such as polyester, polyamide, polyacrylic, and polyurethane fiber. Of these, polyester-based and polyamide-based multifilament yarns are particularly preferable because they have a smooth texture, high elasticity, and excellent quick-drying properties.

In polyester type, polyethylene terephthalate (hereinafter abbreviated as PET), which is usually used for general purposes, has abundant fine yarn types, is easy to make thin, and has many raw yarns with high elasticity. Most preferred. Further, in PET, in addition to the regular type that can be dyed with a disperse dye, there is a copolymerized PET such as a cationic dye dyeable polyester and an easily dyeable polyester, which can obtain a clear color and diversify products. In addition to regular PET, there are polytrimethylene terephthalate (hereinafter abbreviated as PTT) and polybutylene terephthalate (hereinafter abbreviated as PBT) polymer, and latent crimp of a composite fiber in which such polymer and PET polymer are laminated in a bimetal form. Thread can also be applied.

Typical polyamide-based multifilaments are nylon 6, nylon 66, and the like. Compared to PET, a soft texture can be obtained even with a thick yarn, and elasticity and quick-drying properties are also comparable, so that it can be preferably applied. Further, since it can be dyed at normal pressure with an acid dye, it is preferable because it is easy to dye and has a merit that a clear color can be obtained.

Polyurethane fiber has too high elasticity, but it always shrinks and has a rough texture, and when it is stretched, it has too strong binding force, so use it by mixing it with other threads such as nylon in a small amount. Is preferable.

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

In the present embodiment, the total fineness of the multifilament yarn is 5 to 500 decitex, and the single fiber fineness is 0.05 to 10.0 decitex. In particular, a woven fabric having a total fineness of 10 to 300 decitex and a single fiber fineness of 0.2 to 8 decitex is preferable in order to obtain a soft and chewy texture. It is appropriately selected and used according to the thickness and application of the woven fabric. It should be noted that those having a total fineness of less than 5 decitex and those having a single fiber fineness of less than 0.05 decitex are too fine and have a crumpled texture, which is not preferable. Further, those having a total fineness of more than 500 decitex and those having a single fiber fineness of more than 10 decitex are too thick and have a hard texture, which is not preferable.

(Woven thread usage)
To show a specific example of the yarn usage of the woven fabric of the present embodiment, the total fineness of the multifilament yarn is 195 for the gauze fabric equivalent to the 30th to 50th single yarn, which is widely used with the conventional 100% cotton yarn. A yarn of ~ 117 decitex and a yarn having a single yarn fineness of 0.5 to 5 decitex are preferably applicable. Further, the fine yarn equivalent to the 60th to 120th single yarn is preferably a yarn having a total fineness of 97 to 49 decitex, and a single yarn fineness of 0.3 to 6 decitex is preferable. In this embodiment, even for ultrafine yarns equivalent to 180 to 1000 single yarns, which cannot be handled by cotton yarns, yarns having a total fineness of 32 to 5 decitex and a single yarn fineness of 1 to 2 decitex can be used, which is large. There are features.

In the present embodiment, the crimp-developing yarn of the multifilament is not particularly limited as long as it is a yarn in which the elongation rate of the woven fabric is 5% or more and the elongation recovery rate is 50% or more. A growth rate of 15 to 60% is particularly preferable because it has excellent body followability. In addition, those with an extension recovery rate of 60 to 95% do not have the above-mentioned drawbacks called "elbow omission" and "knee omission", are less likely to wrinkle, and have high stretch back properties, so they are comfortable to wear. Excellent and particularly preferable. If the elongation rate is less than 5% and the elongation recovery rate is less than 50%, the elongation and elongation are poor, which is not preferable.

As the crimp-developing yarn, a provisionally processed yarn, a provisionally composite processed yarn, a twisted yarn processed yarn, and a latent crimped yarn are preferable because they exhibit high elasticity while having a soft and smooth texture.

The temporary twisted yarn is specifically a temporary twisted yarn obtained by temporarily twisting PET or nylon 6 yarn with heat of 180 to 220 ° C., or a Taslan composite processed yarn in which a temporary twine yarn is used for the core and two drawn yarns are used for the sheath. Etc., and can be preferably applied to applications that are soft and have a high bulk.

From the viewpoint of the balance between elasticity and smooth texture, the twisted yarn is preferably twisted at a rate of 500 to 2000 times / m in the 140 decitex class, and is exemplified.

The latent crimped yarn is a yarn obtained by composite spinning the above-mentioned PTT / PET or PBT / PET into a bimetal type, and spiral crimping is developed. Since the bulk height is slightly smaller than that of the temporary twine, it is preferable for thin fabric applications.

It should be noted that a processed yarn in which such temporary twisting processing, temporary twisting composite processing, twisting yarn processing, and latent crimping yarn are combined and compositely processed is also preferable. For example, a temporary twisted yarn in which a temporary twisted yarn is combined with a twisting process is preferable because the elasticity is synergistically increased.

In the present embodiment, in addition to using 100% synthetic multifilament yarn for the crimp-developing yarn, vegetable short fibers such as cotton, hemp, rayon and cupra, or long fibers such as rayon and cupra are used for the filament yarn. It is also preferable to use a composite spun-twisted yarn or a blended-twisted yarn. For example, a composite of a crimp-developing yarn in a core and a vegetable short fiber in a sheath is preferably exemplified because it has vegetable water absorption and hygroscopicity and at the same time obtains elasticity of the core yarn.

Next, in the present embodiment, when weaving such a crimp-developing yarn, it is a mixed woven fabric used for either the warp or the weft of the woven fabric, and a 100% synthetic fiber woven fabric used for both the warp and the weft. In the mixed weaving, the woven fabric in which vegetable fibers such as cotton are used for the warp yarns and the crimp-developing yarns are used for the weft yarns has a good balance of water absorption, hygroscopicity, smooth texture of synthetic fibers, elasticity, and quick-drying property. Therefore, it is a particularly preferable woven fabric. The mixing ratio is preferably in the range of 20% to 80% for the synthetic fiber crimped yarn.

In addition, the 100% synthetic fiber woven fabric used for both warp and weft has poor water absorption and hygroscopicity, but it has a softer and smoother texture and quick-drying, so it can be used for inner clothing such as skirts, blouses, and dresses. Outerwear 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, and wool may be blended with cotton. A blend of rayon and cupra has hygroscopicity, and wool has heat retention.

(Processing and finishing method)
Next, the processing and finishing method of the present embodiment will be described. For example, in a mixed woven fabric of warp cotton yarns and crimp-developing yarns of weft polyester, the raw machine is first processed by a cotton smelting (100 ° C., weak alkaline bath) and a bleaching step (100 ° C., hydrogen peroxide bath). At the same time, it is treated with boiling water in this process, so it is confirmed that the width shrinks in the weft direction of the woven fabric and that crimping occurs. Next, the polyester side is dyed with a disperse dye at 130 ° C., the cotton side is dyed with a reactive dye at 80 ° C., dried, and finished by drying heat at 150 to 180 ° C. to finish.

In the mixed woven fabric, when the weft is a cation dye dyeable polyester yarn, it is dyed with a cation dye, and when the weft is a polyamide yarn, it is dyed with an acid dye, and then the cotton side is dyed with a reactive dye to finish. By properly using cationic dyes and acid dyes, it is possible to obtain products with a variety of dyeing designs, such as making them the same color as cotton, making shades different, and making them different colors.

Hereinafter, the present embodiment will be described in detail based on the examples, but the present embodiment is not necessarily limited to these.
"Measuring method"
1. 1. Evaluation of the texture of the gauze fabric (1) Evaluation of the soft texture The fabric is bent in the horizontal direction (weft direction) of the fabric using a pure bending measuring instrument: KES-FB2 (manufactured by Kato Tech), and the average bending at 5 points. Rigidity: B value (gf.cm/cm) was determined. The smaller the value, the softer the bending, the softer the texture, and the better.

(2) Evaluation of repulsive texture Using the same measuring instrument as the evaluation of soft texture, the fabric was bent in the weft direction (weft direction) to obtain the average bending hysteresis: 2HB value (1 / cm ² ) at 5 locations. .. 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 test device for the woven fabric: KES-FB4-AUTO-A (manufactured by Kato Tech), trace the surface of the woven fabric in the weft direction (weft direction) with a friction element, and mean deviation of the surface unevenness. Surface roughness: SDM value was determined. The measurement points were 5 points and represented by the average value. The smaller the value, the smaller the unevenness of the woven fabric surface, the smoother and better. Note that FIG. 3 is a waveform chart obtained by measuring the surface roughness: SDM of the gauze woven fabric of Example 1, Example 2, and Comparative Example 1. The smaller the unevenness of the waveform, the smoother and better.

2. Evaluation of elasticity of gauze woven fabric (1) Elongation rate The elongation rate (%) of the woven fabric in the weft direction (weft direction) was measured by the JIS L1096 B method B-1 method (constant load method). The sample had a width of 50 mm and a length of 300 mm, marked 200 mm, and measured the elongation rate under a load of 1.5 kg. The marked part is the length of the raw cloth, and the elongation rate was calculated by the following formula. The measurement points were 5 points and represented by the average value. The larger the value, the better the extensibility.
Elongation rate (%) = (length of woven fabric under load (L1))-(length of raw cloth (L0)) / (length of raw cloth (L0)) x 100

(2) Stretch recovery rate The woven fabric was measured by the JIS method similar to the stretch rate. After applying a load in the weft direction (weft direction) of the woven fabric, the weight was removed, and the elongation recovery rate (%) after 30 seconds was measured by the following formula. The sample shape, load, and 5 measurement points are the same as those for elongation rate measurement. The larger the value, the better the elongation recovery.
Elongation recovery rate (%) = <(L1-L2) / (L1-L0)> × 100
However, L0 is the length of the raw cloth, L1 is the length under load, and L2 is the length after the load is applied and the weight is reduced.

3. 3. Evaluation of drainage property of gauze woven fabric (1) Residual moisture content The woven fabric was cut to a constant weight of 12.4 g and weighed precisely (cut size is approximately 30 cm square). Next, this is immersed in water for 20 minutes, then the wet fabric is picked up and centrifugally dehydrated for 4 minutes in the dehydration tub of the washing machine, the weight is precisely weighed, and the residual moisture content (%) of the fabric is calculated by the following formula. It was. The smaller the value, the better the drainage property. The better the drainage property, the faster the subsequent drying rate tends to be.
Residual moisture content of the dough (%) = (Weight of the dough after being soaked in water and dehydrated (W1))-(Weight of the dough before soaking in water (W0)) / (Before soaking in water Weight of dough (W0)) x 100

4. Evaluation of quick-drying property of gauze woven fabric (1) Washing and drying time The time until the woven fabric was completely dried was measured by suspending the dehydrated woven fabric by immersing it in the water. Drying conditions are temperature 17 ° C, humidity 50%, wind speed: almost no wind. The weight of the woven fabric was measured every 10 minutes for the drying time, and the weight of the woven fabric was measured every 30 minutes from the middle of drying for the slow-drying woven fabric. The shorter the drying time, the better the quick-drying property.

(Example 1)
(1) Manufacturing method and evaluation method of double gauze woven fabric A. Weaving Weaving Weaving Weaving Weaving Weaving Weaving Weaving Weaving Weaving Weaving Warp yarns are twisted 1050 times / m of cotton yarn No. 40 single yarn, and weft yarns are polyester multifilament, total fineness 148 decitex (equivalent to cotton yarn No. 40 single yarn), 408 filaments, single fiber fineness 0.35 decitex. A processed yarn was used, and a temporary twisted yarn that was twisted 800 times / m was used. This is laminated with the same back surface woven fabric A-2 as the front surface woven fabric A-1 of FIG. 1 on a width of 178 cm and a length of 50 m with a warp density of 100 threads / 吋 and a weft thread density of 84 threads / 吋. The bound double gauze fabric was woven on a dobby loom. The connecting thread was a warp thread, and was intermittently connected at an interval of 8 mm in the length direction and at an interval of 6 mm in the width direction. The mixing ratio of the woven material is 42% polyester and 58% cotton.

B. Finishing processing The weaving raw machine is subjected to cotton scouring (100 ° C, weak alkaline bath) and bleaching process (100 ° C, hydrogen peroxide bath) using a liquid flow dyeing machine, and at the same time, the width of the woven fabric is widened by this boiling water treatment. It was confirmed that it contracted and that crimping occurred in the weft direction (35.4% contraction at a width of 115 cm). Next, the polyester side was dyed with a dark blue disperse dye at 130 ° C. for 40 minutes, and then the cotton side was dyed with a dark blue reactive dye at 80 ° C. for 30 minutes and dried. Subsequently, it was finished and 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, and the double gauze fabric was dyed in dark blue in the same color as polyester and cotton. Table 1 shows the evaluation results of the finished woven fabric.

(Example 2)
The weft was woven and dyed according to Example 1 except that only the processed yarn was used without twisting the weft after the temporary yarn. The finished width was 139 cm, the length was 48.8 m, the warp density was 130 threads / inch, the weft density was 86 threads / inch, and the double gauze fabric was dyed in dark blue in the same color as polyester and cotton. The evaluation results of the finished woven fabric are also shown in Table 1.

(Comparative Example 1)
The same twisted cotton yarn No. 40 single yarn as in Example 1 was used as the warp yarn, and the weft yarn was twisted 800 times / m of the cotton yarn No. 40 single yarn to weave a 100% cotton double gauze fabric. The dyeing was completed according to Example 1 except that the dyeing was performed with a dark 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, the weft density was 86 threads / inch, and the fabric was a 100% cotton double gauze fabric dyed in dark blue. The evaluation results of the finished woven fabric are also shown in Table 1.

(2) Evaluation result

(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, repulsive, has a smooth texture, and has excellent elongation, elongation recovery and drainage, 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 that of the 100% cotton fabric of Comparative Example 1, which was an excellent texture. The elongation rate was 39.8%, and the elongation recovery rate was as high as 82.0%. In addition, the draining property was 1.5 times better than that of Comparative Example 1, and the drying time was 70 minutes, which was 7.5 times, and the drying was extremely fast. In addition, the water absorption rate was confirmed to be water absorption by dropping a drop of water from a height of 10 cm with a dropper at hand and dripping it in 7 seconds. In addition, weaving and dyeing could be performed smoothly without any trouble. This finished gauze fabric was sewn on a blouse and subjected to a practical test. The texture was light, soft and smooth, and it had good physical followability. In addition, the drainage property during washing was good, and it was possible to dry quickly.

B. Example 2
As shown in Table 1, it was a double gauze woven fabric having excellent texture, elasticity, drainage property, and quick-drying property, which was almost the same as the woven fabric of Example 1. In detail, probably because the weft is only a temporary twine and is not twisted, the elongation rate and elongation recovery are slightly lower than in Example 1, but the surface smoothness, drainability, and quick-drying property are excellent. Met. As a result of evaluation according to Example 1, the water absorption rate was 6 seconds, and it was confirmed that the water absorption rate was high.

C. Comparative Example 1
As shown in Table 1, Comparative Example 1 (100% cotton) had a harder texture, no repulsion, and a rough texture as compared with Examples 1 and 2. Further, although the elongation rate was achieved, the elongation recovery was 35.2%, and the elasticity was not achieved. In addition, it was inferior in drainage property and particularly quick-drying property, and was a mediocre dark blue double gauze fabric. The water absorption rate was 5 seconds, and it had water absorption.

(Example 3)
(1) Manufacturing method and evaluation method of double gauze woven fabric A bimetal-type latent crimp-developing yarn with a circular cross section, in which weft yarns are made by laminating polyester multifilament PTT / PET polymers in a crescent shape, with a total fineness of 168 decitex. (Equivalent to cotton yarn No. 31.6 single yarn), 72 filaments, single fiber fineness 2.3 decitex was used, but in accordance with Example 1, warp cotton, weft yarn, and the latent crimp-expressing yarn were interwoven and doubled with a dobby loom. Weaved into gauze fabric. The weaving machine has a warp density of 100 inches / inch and a weft density of 84 lines / inch, a width of 178 cm and a length of 50 m. The mixing ratio of the woven material is 43% polyester and 57% cotton.

Then, scouring, bleaching, dyeing, and finishing were performed according to Example 1 except that the disperse dye and the reactive dye were both pink dyes. The finished width was 142 cm, the length was 48.8 m, the warp density was 118 lines / 吋, the weft density was 86 lines / 吋, and the double gauze fabric was dyed in polyester and pink.

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

(Example 4)
(1) Manufacturing method and evaluation of triple gauze woven fabric The warp yarn is a twisted yarn of cotton yarn No. 60 single yarn at 1200 times / m, and the weft yarn is polyamide nylon 66 with a total fineness of 110 decitex (equivalent to cotton yarn No. 48 single yarn), 96 filaments. , A temporary twisted yarn having a single fiber fineness of 1.15 decitex was used, and a temporary twisted yarn that was further twisted at 600 times / m was used. The same backside woven fabric A-2 and intermediate woven fabric A-3 as the front side woven fabric A-1 of FIG. A triple gauze fabric intermittently tied with a connecting thread was woven on a dobby loom. The connecting thread was a warp thread, and was intermittently joined at intervals of 6 mm in the length direction and at intervals of 4 mm in the width direction. The mixing ratio of the woven material is 33% nylon and 67% cotton.

This raw machine was refined and bleached in the same manner as in Example 1. The nylon side was then dyed with a black gold-containing acid dye at 120 ° C., and then the cotton side was dyed with a yellow reactive dye at 80 ° C. for two baths. Then, it was 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.

The evaluation result of the finished woven fabric was a slightly thick, fluffy and soft texture as compared with Example 1. In addition, it has excellent elongation (24.3%), elongation recovery rate (81.4%), drainability (residual moisture content: 65.7%), and quick-drying (drying time: 80 minutes). It was a characteristic triple gauze fabric dyed in different colors of black and yellow.

As described above, the multiple gauze woven fabric of the present embodiment is soft, repulsive, has a smooth texture, and has excellent elasticity, drainage, and quick-drying properties, which could not be obtained by the prior art. It was.
