Description

Description Fabrics and fabric products that directly touch the skin

The present invention relates to a fabric, and more particularly, to a fabric that directly touches the skin using a composite crimped yarn in which a cellulose multifilament and a synthetic fiber multifilament are mixed and calcined. In particular, the present invention relates to a fabric which has excellent wearability and aesthetic appearance as an undergarment and is suitable as a men's undergarment, and which can be brought into direct contact with the skin, and a fabric product using the same. Background art

Various functions are required for clothing that touches the skin, especially underwear.Especially, it has excellent sweat-absorbing properties and does not stick to the skin, and is excellent in moisture absorption, has little stuffiness, is soft to the touch, and has elasticity. It is an important function to obtain comfortable wearing comfort because it is comfortable and has no feeling of restraint at the time of operation, and it has good sliding comfort. Another important function is that it is less irritating to the skin even when worn repeatedly and is gentle on the skin.

Among men's underwear, men's underwear requires particularly high functionality. In other words, men who sweat more on average than women wear underwear even under hot conditions, so that they can be worn under a Y-shirt and jacket, so it is necessary to sufficiently cope with a large amount of sweat during activities. However, it is required to have a considerably high sweat absorption and to be worn repeatedly every day for many years, so that the skin irritation is required to be extremely small. In addition, it is desirable to have good elasticity, no feeling of restraint during operation, and good sliding comfort. Therefore, for men's underwear, spun yarn materials mainly made of 100% cotton material have been mainly used from the viewpoint of emphasizing the above functionality. This This is because the filament material did not provide satisfactory underwear with a function higher than cotton.

The filament material has unique characteristics such as glossiness and aesthetic appearance that are not found in spun yarn materials, and despite having high functionality that can also be applied to men's underwear, such a filament material The reason why the laminating material was not used as men's underwear is as follows. In other words, clothing made of cellulose multifilament has the characteristics of excellent moisture absorption, glossiness, and softness, but when sweating in large amounts, the amount of sweat exceeds the allowable amount of the material. However, the water-retained clothing sticks to the skin, causing discomfort. In addition, it has the drawbacks that the texture becomes harder than the initial one due to repeated washing, the dimensional stability when wet is poor, the wrinkles are easily formed during the wet drying process, and the wet strength is low. On the other hand, clothing made of a hydrophobic synthetic multifilament has excellent dimensional stability and wet strength, and has little change in texture due to washing.However, due to insufficient moisture absorption, stuffiness during wearing is reduced. growing. In addition, some garments composed of hydrophobic synthetic filaments produce micro-frictional stimuli to the keratinocytes due to the pressure, gap, and wear between the garment and the skin that occur during wearing. In some cases, the skin became reddish or uncomfortable, and people with dry skin sometimes felt itchy in winter.

In addition, clothing made of a material that has been subjected to false twist crimping of a hydrophobic synthetic fiber filament having an irregular cross-section and then formed into a knitted fabric, and that is made of a material that has been subjected to water-absorbing chemical processing, has excellent sweat-absorbing properties, quick drying, and sweat. It has the property that it is not sticky to the skin even if it is applied, but its moisture absorption (anti-moisture) and low skin irritation are not as good as cotton or cellulose multifilament.

In addition, cellulose multifilament and synthetic fiber multifilament Garments made of blended and composite fibers have been developed. In such clothing, the glossy appearance of the cell mouth multifilament and the synthetic fiber multifilament and a unique aesthetic appearance different from spun yarn can be obtained, but in terms of function, a large amount of The point at which the clothes cling to the skin when sweating was not eliminated, and none of the men's undergarments had high functions that were satisfactory.

In this way, in the underwear field, while maintaining the aesthetic appearance of the filament material, the skin does not stick to the skin even when sweating a lot in daily life, and the underwear does not stick to the skin. It has excellent elasticity and has no feeling of restraint during operation.It has excellent slipperiness and has comfortable comfort.Furthermore, there is little frictional irritation between underwear and skin during operation, and it can be worn daily for many years. Underwear with an excellent function of being gentle on the skin has not been obtained. Focusing on the function of being gentle on the skin, there are two types of irritation to human skin by clothing materials: chemical irritation caused by chemical components and physical irritation caused by physical frictional irritation. As for chemical stimuli, there has been widely known a method of evaluating the chemical irritancy of clothing materials using a so-called patch test, and based on the method, a chemical component having a chemical stimulus is not used. Clothing materials with low skin irritation have been developed. However, there was no quantitative evaluation method for the physical irritation of the clothing material to the skin, and no clothing developed with a focus on physical irritation to the skin has been obtained. Atsuta. In fact, skin irritation, which is thought to be caused by physical irritation of clothing materials, is still observed, including mildness such as itching and reddening of the skin when sweating. Disclosure of the invention

The object of the present invention is to solve the above-mentioned problems of the prior art, especially during wearing. No sweatiness, no sticky feeling, no discomfort sticking to the skin, excellent moisture absorption, less stuffiness, refreshing feeling on hot summer days, and soft touch on cold winter days It is comfortable and warm, and has excellent elasticity and slipperiness, so it is comfortable to wear without restriction during operation.Furthermore, there is little physical frictional stimulation of skin keratinocytes, and it has been used daily for many years. Another object of the present invention is to provide a fabric and a fabric product that use a filament material that is gentle to the skin and that can provide an excellent aesthetic appearance, and that is suitable for men's underwear and the like and directly touches the skin.

In view of the above problems, the present inventors have conducted intensive studies to obtain a fabric and a fabric product that directly contact the skin using a filament material having excellent functionality and aesthetic appearance. Wet friction coefficient obtained by evaluating the coefficient of friction of clothing material that has absorbed water (the evaluation method and the like will be described later) and the skin irritation index obtained by the method of evaluating the physical irritation of clothing material to skin ( Evaluation method, etc. will be described later), so that it does not stick when sweating, has little physical frictional stimulus to the skin, and comes in direct contact with skin that is excellent in wearability using a filament material.

Hereinafter, the present invention will be described in detail. First, we will explain the sweat absorption mechanism of fabric that directly touches the skin. The following five factors are important for preventing sweat from sticking to the skin and preventing the fabric from sticking to the skin. First, it is important that the fabric absorbs sweat on the skin as quickly as possible. Second, if sweat is continued, the fabric continues to absorb sweat more and more, eventually exceeding the water retention capacity that the fabric can hold, and a water film is generated on the surface of the fabric (hereinafter, the time when the water film begins to form) The amount of water retention is called the water retention limit), but sweat remains on the skin and the fabric itself becomes sticky to the skin. To prevent this, it is important that the water retention limit of the fabric is high and that it is greater than the range of the amount of sweat when worn. Third, it is important that the absorbed sweat does not seep out onto the surface of the fabric, even if the fabric is compressed and deformed when pressure is applied by the operation. When the fabric is compressed and deformed and the voids are crushed by the pressure, the pore water is easy to seep out, but the bound water is hard to seep out. Fourth, when the wearing condition is observed over time, the quick drying property has the effect of substantially raising the water retention limit. Fifth, when the amount of perspiration is very large, it is important to reduce the area where the water film contacts the skin after reaching the water retention limit and forming a water film on the surface of the fabric. The water retention of the fabric is the sum of the amount retained as binding water by the fibers and the amount retained as void water in the voids between the fibers.

The knitted fabric or woven fabric (hereinafter sometimes simply referred to as a knitted fabric or the like) used for the fabric of the present invention is a mixture of cellulose multifilament and synthetic fibrous multifilament, and at least one of them is false twisted. The used composite crimped yarn is used. The knitted or woven fabric used in the fabric of the present invention only needs to use at least a part of the composite crimped yarn. Also included are knitted or woven fabrics.

In the present invention, the composite crimped yarn is a cellulose multifilament. The yarn and the synthetic multifilament are mixed with each other by disturbing the arrangement of the single yarns, and have a structure having many voids in the yarn by crimping. In that case, it is sufficient that at least one of the cellulose multifilament and the synthetic multifilament is false twisted. When both are false twisted, the cellulose multifilament single yarn has a relatively weak crimp, and the synthetic multifilament single yarn has a relatively strong crimp. Therefore, there are many synthetic multifilament single yarns near the surface of the composite crimped yarn, and there are many cellulose multifilament single yarns at the center. I like it.

For this reason, according to the fabric of the present invention, the excellent hygroscopicity of the cellulose multifilament makes it possible to obtain comfortableness that is resistant to stuffiness even on a humid day, and also to reduce the moisture absorbed by the cellulose multifilament. A large amount of water can be retained as void water between the single yarns that can be held as the binding water of the fibers and increased by the crimping of the processed yarn, and in the case of the knitted fabric, between the loops. Water holding capacity is greatly increased.

In addition, because it retains sweat even as cellulose-bound water, sweat does not easily seep out of the fabric even when pressure is applied. In addition, since the cellulose multifilament and the synthetic fiber multifilament are mixed with each other, the diffusion effect of sweat in the yarn and the fabric is high due to the mutual effect, and as a result, the drying speed of the fabric is reduced. Because of the speed, the practical water holding capacity limit is further increased. In addition, the sweat absorbed from the skin surface gradually shifts to the center of the yarn over time, and is unevenly distributed, and leaps out of the surface of the yarn in a gentle curved line. The presence of the synthetic multifilament single yarn produces a spacer effect between the skin and the moisture inside the yarn, and prevents stickiness to the skin.

In the composite crimped yarn used in the present invention, the crimp elongation is an index of the strength of the crimp, and the fabric which directly touches the skin, which is the object of the present invention, is used. It is very deeply involved in all functions. That is, the higher the crimp elongation ratio, the higher the elasticity of the fabric. In particular, in the case of a composite crimped yarn, the crimp elongation is determined by the strength of the disorder of the single yarn arrangement of the single yarn of the cellulose multifilament and the single yarn of the synthetic multifilament, This is reflected in the strength of mixing, the amount of voids in the yarn of the composite crimped yarn, and the like. For this reason, if the crimp elongation rate of the composite crimped yarn is too small, the sweat treatment function by the above mechanism cannot be achieved. In the case of a composite crimped yarn, the crimp elongation is too high, as described above, because it reflects the disorder of the single yarn arrangement of the single yarn of the synthetic multifilament. However, due to the physical irritation caused by the single yarn of the synthetic multifilament, the skin irritation tends to be strong, and the touch and feel tend to be poor.

In the composite crimped yarn used in the present invention, the area of the overlapping region of the dispersion region of the single yarn of the cellulose multifilament and the dispersion region of the single yarn of the synthetic multifilament is large. The ratio (A) of the dispersed area of the single yarn of the unit to the area SG is an index of the degree of mixing of the single yarn of the cell opening and the multifilament and the single yarn of the synthetic multifilament. Strongly involved in processing functions. That is, as A is larger, the single yarn of the synthetic multifilament and the single yarn of the cellulose multifilament are more uniformly mixed, and the water absorption speed is improved. In particular, when A is 50% or more, the water absorption rate is dramatically improved, and a sufficient water absorption rate can be obtained without prescribing a water-absorbing agent in the fabric dyeing and finishing step.

Furthermore, since the composite crimped yarn used in the present invention is made of filament, the friction between the yarn and the yarn is smaller than that of the spun yarn, and does not hinder the deformation of the knitted fabric. For this reason, the undergarment excellent in elasticity and elasticity recovery can be obtained by the fabric of the present invention. Furthermore, since the knitted fabric is made of filament, the surface slides well, and the outer Also good sliding with outer clothing. As a result, it is possible to obtain a comfortable feeling with a feeling of fit to the body without being confused even when layered, without feeling of restraint during operation.

Cellulose multifilament is an excellent material with low skin irritation. This is a material characteristic of cellulose, and in the present invention, furthermore, because of the morphological characteristics of the filament, there is almost no yarn end in the knitted fabric as seen in spun yarn, so that skin irritation is further increased. Is low. In the case of 100% cellulose multifilament fabric, when the washing is repeated, the filaments are likely to converge due to the repetition of dry and wet, and the fabric becomes hard and the skin irritation increases. However, as in the present invention, the convergence of the cellulose multifilament can be suppressed by combining with the synthetic multifilament by false twisting and mixing. However, skin irritation can be kept low even after repeated washing.

Also, with a 100% cellulose multifilament fabric, a large amount of sweat may cause stickiness to the skin, and if the skin is wet and physical stimulation is applied, the stratum corneum may be damaged Force <In the fabric of the present invention, the synthetic fiber multifilament is separated into single yarns by mixed fiber false twist, and a gentle curve form (single curve) is formed between the single yarns of the cellulose multifilament. ) On the surface of the composite crimped yarn. For this reason, when no pressure is applied, the rate at which the synthetic multifilament first touches the skin is higher than the rate at which the cellulose multifilament touches the skin. Combining the anti-tacky effect (spacing effect with synthetic fiber multifilament) reduces skin irritation.

In other words, with 100% cellulose, the skin irritation index when wet when the fabric is wet due to sweating, etc. is compared with the skin irritation index when dry. By applying false twisting with synthetic multi-filament, the difference between the dry skin irritation index and the wet skin irritation index can be kept small. It is possible to obtain underwear that is gentle on the skin with little skin irritation even when it is wet.

In addition, as described later, as synthetic fiber multifilament, it is possible to absorb water (e.g., due to capillary action) such as w-shaped cross-section flat yarn, eyeglass-shaped flat yarn, cross-section flat yarn, and cross-shaped cross-section yarn. By using a yarn having an excellent cross-sectional shape, the rate of water absorption into the fabric is increased, and the diffusivity of sweat in the fabric is increased. As a result, quick drying can be improved. That is, it is possible to quickly absorb the sweat on the skin and obtain a fabric excellent in quick drying property.

The fabric of the present invention only needs to have the above-described knit or woven fabric, and includes at least a part of the fabric having the above-described knit or woven fabric.

In the present invention, the fabric refers to a fabric that directly touches the skin, and can be suitably used for applications such as clothing, bedding, towels, and handkerchiefs that directly touch the skin.

Examples of the clothing include outer clothing, inner clothing, pajamas, socks, and the like.

The outer garment is not limited as long as it is worn in direct contact with the skin, and includes outer garments that can be seen from the outside, such as T-shirts and poro-shears. Shoes, cutsaws, sweaters, sportswear, work clothes, blouses, jackets, jackets, swimwear, pantswear, pants and the like.

Examples of inner clothing include underwear, T-shirts, and long pants

, Under trousers, spats, trunks, bluffs, men's foundations with body-correcting effect, women's rangeries, foundations Yon, shorts, children's underwear, briefs, shorts, etc. Examples of women's lingerie include camisoles, slips, petticoats, flared pants, body pre-fillers, and teddies. Examples of women's foundations include brassiere, girdle, and clothing that have a body-shaping effect, such as body suits.

Further, the fabric of the present invention is suitably used as bedding such as sheets, blankets, pillowcases, etc., which require direct contact with the skin for a long period of time and require sweat absorption. Further, it can be suitably used as towels and handkerchiefs. BRIEF DESCRIPTION OF THE FIGURES

Figure 1 is a schematic diagram of the device used to measure the skin irritation index. BEST MODE FOR CARRYING OUT THE INVENTION

The knitted or woven fabric used in the fabric of the present invention is knitted or woven using a composite crimped yarn in which cellulose multifilament and synthetic multifilament are mixed and at least one of which is false twisted. It is obtained by doing.

In the composite crimped yarn used in the present invention, the mixing ratio of the cellulose multifilament is 15 to 85 wt%, preferably 20 to 85 wt%.

More preferably, it is 45 to 65 wt%. If the mixing ratio of the cell mouth-to-multifilament is less than 15 wt%, the moisture absorption required for a fabric that directly touches the skin is insufficient. When the amount exceeds 85 wt%, the fabric clings to the skin when a large amount of sweat is generated, causing discomfort, and a change in feeling due to repeated washing occurs.

The total fineness of the composite crimped yarn must be 44 to 33 33 dtex. It is important. The more suitable range depends on the application.For outer use, 1667 to 3333 dtex is preferable, for T-shirt use, 1667 to 278 dtex is preferable, and for men's underwear use. 111 to 200 dtex is suitable, and 44 to 167 dtex is suitable for women's innerwear. If the total fineness of the composite crimped yarn is less than 44 dtex, the sweat treatment function required as a fabric that directly touches the skin is insufficient. If it exceeds 33 33 dtex, it will become thick and stiff, and it will not be comfortable, and it will tend to be uncomfortable.

The single fiber fineness of the cellulose multifilament is 0.1 to 5.6 dtex, more preferably 2.8 dtex or less, and further preferably 1.4 dtex or less. If the single yarn fineness of the cellulose multifilament exceeds 5.6 dteX, the feel becomes poor.

The single fiber fineness of the synthetic multifilament is 0.1 to 5.6 dtex, preferably 2.2 dtex or less, and more preferably 1.4 dtex or less. If the single-filament fineness of the synthetic multifilament exceeds 5.6 dtex, the feel and touch will deteriorate, and a fabric with sufficiently small skin irritation cannot be obtained. When the single yarn of the cellulose multifilament and / or the single yarn of the synthetic multifilament is 1.4 dtex or less, the openability is good so that the single yarn does not converge at the time of blending. It is preferable to use a yarn oil with good twisting properties and select a lower fiber mixing condition. For example, it is preferable to set the fiber mixing conditions to lower the fluid pressure and lower the feed rate. The fluid pressure is preferably 4.9 X 10 ⁴ to 2.0 X 10 ⁵ Pa and the feed rate is preferably 0.1 to 2.0%.

The crimp elongation of the composite crimped yarn is more than 4.0% and 35% or less, preferably 8.0 to 25%, and more preferably 10 to 2%.

5%. When the crimp elongation rate is 4.0% or less, the sweat treatment function and elasticity are insufficient, and when it exceeds 35%, the fabric becomes highly irritating to the skin. . When the crimp elongation is at least 10%, a fabric having a particularly high sweat-treating function and sufficient elasticity can be obtained. In particular, when the content is in the range of 10 to 25%, the fabric directly touches the skin, and has a sufficiently high sweat treatment function, sufficient elasticity, good touch, and less skin irritation. However, since the fabric has a very good balance of functions, it is possible to obtain a tremendously comfortable feeling when using the fabric.

The cellulose multifilament used in the present invention includes, for example, a cellulose filament made of copper ammonia rayon (Cubra), viscose rayon, polynoic rayon, and the like. Ramen.

The spinning method of the cellulose multifilament is not limited, and can be obtained by a known method such as a Hank method, a cake method, a spool method, a net process method, and a continuous method. Also, two or more of these yarns may be used in combination. Among these, the cellulose multifilament spun by the net process method has a weak convergence between the single yarns of the cellulose filament, so that the fiber multifilament can be more uniformly mixed by fluid entanglement. This is preferable because it is easy to be entangled with the laminant, the cellulose filament single yarns do not converge apart from each other, and a soft-touch fabric can be obtained, and the hardening of the fabric during washing can be suppressed. In addition, since the cellulose multifilament spun by the net process has a high yarn elongation, the settable condition range in false twist crimping is wide, and the twisting tension can be increased. Therefore, it is possible to obtain a composite crimped yarn having a higher swelling and a higher sweat treatment function.

In addition, the cellulose multifilament can contain an anti-glazing agent such as titanium oxide or various known additives depending on the purpose.

Synthetic multifilaments include polyethylene terephthalate , Polybutylene terephthalate, polytrimethylene terephthalate, normal pressure dyeable polyester, polyamide, polyamide, polyolefin, polyacrylonitrile, or a copolymer thereof. G.

The spinning method of these synthetic multifilaments is not particularly limited. For example, a method of using undrawn yarn or semi-drawn yarn wound at a winding speed of about 150 m / min, Known methods such as a method of twisting a yarn or a semi-drawn yarn to about 2-3.5 times, a direct drawing method in which a spinning and a drawing and twisting steps are directly connected, and a high-speed spinning method with a winding speed of 500 Om or more. It can be obtained by the method.

The cross-sectional shape of the single yarn of the synthetic multifilament yarn is not particularly limited, and is round, flat, triangular, L-shaped, T-shaped, Y-shaped, W-shaped, π-shaped, cross-shaped, well-shaped, and Yatsuha-shaped. , Hateki type, Glasses type, Glasses type Two-hole hollow, Polygonal type such as dogbone type, multi-leaf type, One-hole hollow type, Multi-hole hollow type, or irregular shape These may be mixed. Of these, Υ-type, W-type, cross-shaped, well-shaped, glasses-type, glasses-type two-hole hollow, L-type, etc. are preferable because of their excellent wicking property due to capillary action and high water absorption. . Also, round flat yarns, W-shaped flat yarns, eyeglass-shaped flat yarns, eyeglass-shaped two-hole flat yarns, flat-shaped yarns, and other cross-sectional shapes with a small bending Young's modulus have little frictional irritation to the skin. , Preferred. W-shaped flat yarns, eyeglass-shaped flat yarns, eyeglass-shaped two-hole flat yarns, and π-shaped flat yarns are particularly preferred as having both sweat absorption properties and low friction irritation to the skin.

In the composite crimped yarn, the area of the overlapping area of the dispersion region of the single yarn of the cellulose multifilament and the dispersion region of the single yarn of the synthetic multifilament is large. The ratio (Α) of the yarn dispersion area to the area SG is preferably 30 to 95%, more preferably More preferably, it is 50 to 95%. When the content is 30% or more, the degree of mixing of the single yarn of the cellulose multifilament and the single yarn of the synthetic multifilament is good, and the water absorption speed is improved, and comfort can be obtained. In particular, when the content is 50% or more, an extremely fast water absorption rate can be obtained without prescribing a water absorbing agent in the dyeing and finishing step of the fabric, which is very preferable.

The dispersion region of the multifilament single yarn is defined as the dispersion of the filament single yarn in the cross section of the composite crimped yarn in which different multifilaments are mixed. The area that exists.

Next, a method for producing the composite crimped yarn of the present invention will be described. However, as long as a composite crimped yarn that can achieve the object of the present invention can be obtained, any method may be used. Either the fiber or the false twist may be used first, and the production method is not limited.

As a method of blending the cellulose multifilament yarn and the synthetic fiber multifilament yarn, for example, an air-entanglement method called interlace or an electric fiber opening method using electrostatic force is used. And confounding them. In the present invention, it is necessary that the single yarn of the cellulose multifilament and the single yarn of the synthetic multifilament are interlaced at least intermittently, and the single yarns of these filaments are each single yarn. It is preferable that the single yarns are mixed as uniformly as possible without being converged by themselves, and that the single yarns are separated from each other without sticking and contain air between the single yarns.

In the case of the interlace method, the number of entanglements is preferably 20 or more and 120 or less per 1 m of yarn length from the viewpoint of uniform blending. More preferably, the number is 70 or more and 120 or less. If the number of entanglements is less than 20, single yarns may not be uniformly mixed. If the number of confounds exceeds 120, the swelling of the threads will decrease, and the sweat-treating function will tend to decrease. Intensity tends to increase.

The false twisting method for imparting crimp is not particularly limited as long as false twisting can be performed and heating can be performed in the false twisting zone, and generally used belt nip type, pin type, and free wire are used. A cushion type, an air-twist type, or the like can be used.

The false twisting may be performed before the above-described intermingling of the fibers, but in order to perform a more uniform mixing, it is preferable to perform the intermingling of the fibers first and then perform the false twisting. Also, if false twisting is performed by the belt nip method after intertwining the fibers, the yarn is twisted in the false twisting step, and the cellulose single yarn and the synthetic single yarn are more uniformly mixed, which is preferable.

In addition, it is preferable to use a device capable of continuously performing mixed fiber entanglement and false twisting because of high productivity.

Further, winding after processing is preferably performed at a tension of 0.08 cN dtex or less so as not to break the structure of the composite crimped yarn, which is a preferable manufacturing process. Two examples will be described.

In the first example, the cellulose multifilament and the synthetic multifilament are mixed by air entanglement and then false twisted. In this case, the preferred ranges of the feed rate and the interlace pressure are determined by the type of the cellulose multifilament yarn, the type of the synthetic multifilament yarn, the specifications of the device, and especially the interlace for air-entanglement. Although it depends on the shape of the race nozzle, the feed rate is preferably 0.1 to 5% in the overfeed region, and more preferably 0.5 to 2.0%. Also, Lee pointer one race ^{pressure, 4. 9 xl 0 4 ~ 4.} 9 X 1 0 5 P a is the preferred, 9. 8 X 1 to be al ^{0 4 ~ 2. 0 X 1 0} 5 P a Stronger and more suitable.

If the feed rate exceeds 5%, the machining tension will fluctuate, May not be mixed. When the feed rate is lower than 0.1%, in the case of the feeder feed, interlace entanglement becomes insufficient, and the functionality such as water absorbency of the fabric may be reduced. If the Lee printer one race pressure is greater than ^{4. 9 X 1 0 5 P} a, or fluff is generated in the cellulose off I lame down the door, lean it takes is poor finish thread of the false twist, sweat processing function of the fabric May decrease. If Lee pointer one race pressure is less than ^{4. 9 X 1 0 4 P} a, y pointer one race intertwined becomes insufficient, the functionality of the fabric may be reduced.

In order to uniformly obtain the composite crimped yarn satisfying the object of the present invention, for example, the shape of the nozzle of the interlace is preferably such that air is blown at an angle of 85 degrees or less with respect to the running direction of the yarn.

The conditions of the false twist in the subsequent false twisting process depend on the melting point of the synthetic multifilament, the specifications of the heater of the processing machine, and the processing speed, but the temperature of the heater before false twist is 100 ° C to 190 ° C. The temperature is preferably from 120 ° C to 190 ° C, and more preferably from 150 ° C to 180 ° C. If the temperature of the heater before false twisting is less than 100 ° C, it is difficult to obtain sufficient crimping, and if the temperature is higher than 200 ° C, the cellulose single yarn hardens and is rough. The skin becomes soft and may cause irritation to the skin. Also, the false twist method is preferable because the belt nip method is used, and the cellulose multifilament and the synthetic fiber multifilament are mixed well with each other to easily obtain a highly functional composite crimped yarn. The draw ratio in the false twisting step is preferably performed in an overfeed range of 0 to 5% for stable production. More preferably, it is a 0 to 2% overfeed area.

In order to stably obtain a composite crimped yarn satisfying the object of the present invention, the twisting tension is preferably 0.16 to 0.27 cdte X, and the untwisting tension is 0.0. 7-0.27 c NZ dte X is preferred. The number of twists is [(2300 000 ZB ' ^{/ 2} ) + 590] x 0.80 (times m) or more, and ((2300 000 ZB ^{I / 2} ) + 590] x 0.95 (times Zm) The following is preferable in order to achieve the object of the present invention. Note that B- (dteX) X9Z10 is obtained as described above.

A preferred second example is a method in which false twisting is first performed only on the synthetic multifilament, and then the false twisted synthetic multifilament and cellulose multifilament are mixed. The conditions for false twisting of the synthetic fiber multifilament depend on the melting point of the synthetic fiber multifilament, but the temperature before the false twisting is preferably 100 ° C to 220 ° C, more preferably 1 ° C. It is between 20 ° C. and 190 ° C., more preferably between 150 ° C. and 190 ° C. When the temperature of the heater before false twist is less than 100 ° C, it is difficult to obtain sufficient crimp. It is also preferable to use a set heater after false twisting because the skin irritation tends to be reduced. The set heater temperature is preferably from 100 ° C to 190 ° C. The draw ratio in the false twisting step is preferably 0.95 to 1.05 for stable production.

Twist number is [(2 3 0 0 0 8 ^1/2) + 5 9 0]> 0.7 0 (times ^/ m) or more, [(2 3 0 0 0/8 ^{'/ 2)} + 5 9 0 1.0 (times 111) The following is preferable in order to achieve the object of the present invention. Note that, as described above, B = (dtex) X 9/10.

In the subsequent blending process, the preferred range of the feed ratio and the interlace pressure as the blending conditions of the false twisted multifilament and the cellulose multifilament is cellulose. The strength of the cellulose fiber filament varies depending on the type of multi-filament yarn, the type of synthetic multi-filament yarn, the specifications of the device, and in particular, the shape of the interlace nozzle for air entanglement. The feed rate is preferably 0.1 to 5%, more preferably 0.5 to 2.0%, in the open feed area. In order to obtain a fabric with an excellent sweat treatment function, a synthetic fiber multi It is preferable to make the feed rate of the filament 0.1 to 5% larger than the feed rate of the cellulose multifilament. Also, Lee emissions Thale Ichisu ^{pressure, 4. 9 X 1 0 4} ~ 4. 9 X 1 0 5 P a is preferably der is, made et ^{9. 8 X 1 0 4 ~} 2. 0 X 1 0 ⁵ Pa is more preferred o

If the feed rate of the cellulose multifilament is more than 5%, the working tension may not be stable and uniform fiber mixing may not be performed. When the feed rate is less than 0.1% or underfeed, interlace entanglement becomes insufficient, and the functionality such as water absorbency of the fabric may be reduced. If the interlaced pressure is greater than ^{4. 9 1 0 5 P a} , or fluff is generated in the cellulose Multi-lame down the door, lean thin it takes is poor will finish the thread of the false-twisting, fabric sweat processing functions of May decrease. If Lee pointer one race pressure 4. less than 9 X 1 0 ⁴ P a, there is a case where interlaced interlacing is insufficient, the functionality of the fabric is lowered.

The knitted fabric used in the present invention preferably has a wet friction coefficient of 3.0 or less, more preferably 2.0 or less, which is an index indicating the stickiness of the fabric to the skin. When the coefficient of friction of the knitted fabric exceeds 3.0, the feeling of stickiness and wetness of the fabric at the time of perspiration increases, and discomfort may increase. When the wet friction coefficient is 2.0 or less, the feeling of stickiness and wetness is further reduced, and the sensation when using the fabric is remarkably comfortable.

In the knitted fabric used in the present invention, the SB value defined by the following formula (2), which is a measure of refreshing sensation in a sweaty condition, satisfies the following formula (1), and the following formula (4) It is preferable that the SN value, which is a measure of coolness under the condition where sweat flows, defined by the formula (3), satisfies the following equation (3). 0.0 <SB <1 0 0. 0 …… (1)

S B = 1.08 x (heat dissipation) + 1.98 x (surface unevenness) + 6.25 X (surface friction coefficient) — 1 3.92 (2)

0.0 <S N <1 0 0. 0 ...... (3)

S N =-0.03 (water flow) + 1.42 x (degree of humidity transfer) +

1 7> <(heat dissipation) + 0.76 X (surface irregularity) + 1 2.1 X (surface friction coefficient) 1 16.6 …… (4)

That is, if the SB value, which is a measure of the refreshing sensation in the situation of sweating, and the SN value, which is the measure of the refreshing sensation in the condition of sweating, are larger than 0 and less than 100, the fabric is When used, it gives a refreshing feeling and comfort in both sweaty and sweaty conditions. When the product of the SB value and the SN value is 0.5 or more, the refreshing feeling is further improved.

The above SB and SN values are derived from the following tests by the present inventors as a measure of refreshing sensation.

That is, a large number of different fabrics such as fiber types, fiber structures, fiber combinations, knitted fabric types, knitted fabric structures, etc. are produced, and sewed as inner for the upper body. A wear test was conducted to extract the factors that contribute to the refreshing sensation. Specifically, a large number of wearing testers are selected, prototype clothing is distributed with the details turned down to the wearing testers, and they are used daily for a long period of time. Evaluation of eight factors was performed for each wear. As a result, in a situation of sweating, non-stickiness, no stuffiness, and a soft touch were the three main criteria for judging the refreshing sensation, but in a situation where sweat is flowing, it is sticky with sweat In addition to the fact that the fabric does not stick to the skin and that it does not stick to the skin, the fact that heat does not accumulate was used as a criterion for judgment, and it became clear that the importance of the above-mentioned touch items was lowered. Next, the physical properties of the knitted fabric subjected to the wear test were measured in terms of water, physical properties related to moisture, physical properties related to heat, physical properties related to surface shape, physical properties related to texture, and the degree of deformation of the fabric. Analyzing the relationship with the above sensory evaluation results, grasping the physical properties of the fabric that contributes to the refreshing sensation and its importance, and as a measure of the refreshing sensation, the SB value is calculated by the above equation (2), and the SN value is calculated by the above formula (2). In the above equations (2) and (4), which are defined by equation (4), the amount of heat radiation (WZm ² · ° C) refers to the ability to release the heat in clothes to the outside, and the preferred range is 1 is a 0 ~ 1 5 WZm ^2. The surface irregularity refers to the degree of irregularity of the fabric on the side in contact with the skin surface, and the preferred range is 0.2 to 1.5. The surface friction coefficient refers to the resistance of the fabric on the side in contact with the skin to slip, and the preferred range is 0.20 to 0.35. The amount of water infusion (%) refers to the difficulty of the sweat absorbed by the fabric to return to the skin, and the preferred range is 0 to 50%. Humidity transfer refers to the ability to release the moisture in clothes to the outside, and the preferred range is 10.0 to 11.0. These can be measured by the method described below.

Further, in the present invention, it is preferable that the skin irritation index of the above-mentioned knitted fabric or the like when dried is 8.0 S or less. Friction stimuli increase and people with sensitive skin may feel itchy or reddened in some seasons.

The skin irritation index is an index indicating the degree of friction irritation caused by the contact between the fabric and the skin during use, and can be measured by the evaluation method proposed by the present inventors. This evaluation method utilizes the phenomenon that when the horny substance is separated by physical stimulation due to friction, the inner layer of the horny substance comes out to the skin surface, thereby increasing horny water. A frequency (frequency of about 3.5 MHz) is applied, and the change in horny water is measured as an admittance (Siemens [S]) of electricity. The details of the measurement method will be described later.

Furthermore, when the fabric is composed of a knitted fabric, the fabric is excellent in elasticity and elasticity and recoverability, has no feeling of restraint during operation during wearing, is easy to move, and has an excellent fit to the body. From the viewpoint of obtaining a tensile strength, the elongation stress of the knitted fabric at the time of 50% elongation in the vertical direction is preferably 20 cNZcm width or less, more preferably 15 cNZcm width or less. Further, it is preferable that the elongation stress at the time of 80% elongation of the knitted fabric in the weft direction is not more than 20 cNZcm width, more preferably, 1 to 15 cNZcm width. Further, the elongation recovery rate at 50% elongation in the vertical direction of the knitted fabric is preferably 80% or more, more preferably 85% to 100%, and the knitted fabric in the horizontal direction is stretched. The elongation recovery rate at 100% elongation is preferably 80% or more, and more preferably 85 to 100%.

The knitted fabric of the present invention preferably has a mass per unit area of 80 g to 250 g / m ² , more preferably 80 g to 180 g / m ² . If the mass per unit area of the knitted fabric is less than 80 g / m ² , the sweat treatment function may be insufficient, and if it exceeds 250 g / m ² , the weight may be too heavy to deteriorate the grounding.

In the present invention, the method of forming the composite crimped yarn into a knitted or woven fabric is not particularly limited, and the yarn can be manufactured using a normal knitting machine or a loom. It is also possible to mix and knit with other materials such as spandex synthetic fiber, cotton and silk.

The organization of knitted goods is rice, smooth, sheeting, Kanoko, single bag, punch roma, Milano ribs, pearl knit, etc., round knitting, flat knitting, half tricot, twin Trident organizations such as Double Denbi, Atlas, Russell organizations such as Satinnet and Triconet, A weft insertion structure is used. Further, these changed structures are also possible and can be appropriately selected according to the purpose. However, it is preferable to use a knitted structure having a relatively coarse density and a high elasticity.

For example, in the case of a smooth structure, it is preferable that the loop length (cm) of the stitch constituting the knitted fabric and the total fineness D (dtex) of the composite crimped yarn satisfy the following expression (5), and more preferably Equation (6) must be satisfied.

2. 9 (cm) ≤ (L / D ^1/2 ) x 1 0 …… (5)

3.8 (cm) ≤ (L / D1 / ² ) 100 ... (6) In the case of a rice texture, the loop length L (cm) of the stitches that constitute the knitted fabric and the composite crimped yarn It is preferable that the total fineness D (dtex) (7) is satisfied, more preferably that the following formula (8) is satisfied.

2. 1 (cm) ≤ (L / D ^1/2 ) X 10 0 …… (7)

3.1 (cm) ≤ (L / D ^1/2 ) X 100 …… (8) In the case of a sheet-in-woven fabric, the loop length L of the stitch forming the knitted fabric and the total fineness D (dte X) It is preferable to satisfy equation (9)

0

2. 1 (cm) ≤ (L / D ^1/2 ) X 100 ... (9) In the above-mentioned tissue, if formulas (5), (7) and (9) are not satisfied, sweat treatment Function and heat retention may be insufficient.

Examples of the structure of the woven fabric include plain weave, twill weave, satin weave, and their changed structures.

The method of processing the knitted or woven fabric used in the fabric of the present invention is not particularly limited, and may be dyed in addition to white by bleaching / bleaching. For example, the yarn-dyed method in the state of yarn such as whole or cheese, that is, the composite dyed yarn, the post-dyeing method in the state of knitted or woven fabric, etc. These methods may be used as dyes, dyeing assistants, and finishing agents.

Any commercially available synthetic fibers and those used for dyeing Z or cellulose fibers can be arbitrarily selected according to the purpose. Also, the use of a fluorescent whitening agent is optionally possible. In dyeing knitted or woven fabrics, scouring, bleaching and bleaching are usually performed prior to dyeing, and an alkali treatment is performed to improve the dyeing properties of cellulosic fibers. Pre-treatments such as weight loss may be applied.Furthermore, in the case of a finish set, setting conditions such as stretching are necessary to obtain a fabric with a soft texture, excellent skin irritation, and a high sweat treatment function. I like it. If the setting effect is too strong, the crimp of the composite crimped yarn in the fabric may be impaired, and the sweat treatment function and elasticity may be reduced. On the other hand, if the setting temperature is too high, the cellulose multifilament in the fabric may be hardened, the texture may become hard, and skin irritation may become strong. Specifically, in the case of the wet heat set method, the hand may harden under the setting conditions of 180 ° C and 1 minute or more, and in the case of the dry heat set method, 190 ° C. C, The texture may harden under the setting condition of 1 minute or more.
