Description

CLOTH AND CLOTH PRODUCT TO BE BROUGHT DIRECTLY IN TOUCH WITH HUMAN SKIN}

The present invention relates to a fabric, and more particularly, a fabric in which cellulose multifilament and synthetic fiber multifilament are mixed and directly contacted with skin using a combustible composite crimping process, particularly having excellent wearability and aesthetic appearance as an undergarment, The present invention relates to a fabric directly contacting skin suitable for men's undergarments and a fabric product using the same.

Various functions are required in clothing, such as clothing that directly touches the skin. Among them, the sweat absorbency is excellent, the skin is not sticky, the hygroscopicity is excellent, the sweating is low, the skin feels soft and the elasticity is excellent. There is no restraint at the time of operation and good slipperiness is a comfortable function to get a comfortable wearing feeling. It is also an important function that the skin is less irritated even after repeated wearing, so that the skin is friendly.

Among them, particularly high functionality is required for new use. In other words, even when a man with a lot of sweating on average is hotter than a woman, he wears his underwear in a shirt and a jacket, so it is necessary to cope with a large amount of sweat during the action, which requires a very high sweat absorption, and over a long period of time. Since repeated daily wear, very small irritation to the skin is required. Moreover, it is excellent in elasticity, there is no restraint feeling at the time of operation | movement, and it is calculated | required to be a comfortable wearing feeling with good slipping property. Therefore, in the new use, a spun yarn material mainly based on 100% cotton material has been mainly used in view of the above-mentioned functionality. This is because in the filament material, satisfactory underwear having a function of more than a plane could not be obtained.

Although the filament material has characteristics such as a unique glossiness and aesthetic appearance that are not present in the yarn material, and although it has a high functionality that can be applied as a new yarn, such a filament material could not be used as a new yarn for the following reasons.

In other words, clothing made of cellulose multifilament is characterized by excellent hygroscopicity, glossiness, and skin feel. However, when sweating in large quantities, the amount of sweat exceeds the allowable amount of the material and the water-containing clothing adheres to the skin, causing discomfort. This happens. In addition, there is a drawback that the texture becomes harder than the initial stage due to repeated washing, the dimensional stability during wetness is poor, the wrinkles are easy to be wrinkled during the wet drying process, and the wet strength is low.

On the other hand, clothes made of hydrophobic synthetic filament multifilament have excellent dimensional stability and wet strength, and have a small texture change due to washing, but lack of hygroscopicity, resulting in increased sweating during wearing. In addition, some garments made of a part of hydrophobic synthetic filament may cause minute friction stimulation on keratinocytes due to compression, misalignment, and squeezing between the garment and the skin generated during wearing, resulting in redness of the skin or feeling of discomfort. Some people with dry skin feel itching in the winter.

In addition, garments made of a hydrophobic synthetic fiber filament of a cross-section of a cross section and made of a knitted fabric after flamming crimping and absorbing chemically processed are excellent in sweat absorption, high in fast drying and not sticky to the skin even after sweating. Although it can obtain, it is less than cotton or cellulose multifilament about hygroscopicity (ability to prevent sweating) and low skin irritation.

Moreover, the garment which consists of a fiber mixed with the fiber by combining cellulose multifilament and a synthetic fiber multifilament has been developed. In such garments, a unique aesthetic appearance that is different from the glossiness or spun yarn of cellulose multifilament and synthetic fiber multifilament can be obtained, but in terms of function, the clothing does not stick to the skin at a large amount of sweating during wearing. In particular, there was no thing which could satisfy | fill satisfactory as new underwear.

In this way, while maintaining the aesthetic appearance of the filament material in the field of inner skin, even when a lot of sweat in everyday life, the skin is not sticky, the inner body does not stick to the skin, the elasticity is excellent, there is no restraint during operation, Excellent slipperiness, comfortable fit, less friction stimulation between the inner and skin during operation, and even if worn repeatedly over a long period of time for a long time did not obtain an excellent function of soft to the skin.

In addition, paying attention to the soft skin, there are chemical stimuli derived from chemical components and physical stimuli derived from physical frictional stimuli. Until now, the chemical stimulation of the clothing material by the so-called patch test for the chemical stimulation is widely known, and based on this, a clothing material having less skin irritation has been developed in a direction that does not use chemical components with chemical stimulation. However, since there was no quantitative evaluation method for the physical stimulation of the skin of the clothing material, it was a phenomenon that the clothing developed by paying attention to the physical stimulation of the skin was not obtained. In fact, if it is itchy, including mild to reddish skin at sweating, skin irritation that is thought to be due to physical stimulation of the clothing material is still observed.

1 is a schematic diagram of an apparatus used to measure skin irritation index.

Best Mode for Carrying Out the Invention

The knitted fabric or woven fabric used in the fabric of the present invention can be obtained by knitting or weaving using a composite crimping fabric in which cellulose multifilament and synthetic fiber multifilament are mixed and at least one of them is combustible.

In the composite crimping work used in the present invention, the mixing ratio of the cellulose multifilament is 15 to 85 wt%, preferably 20 to 60 wt%, more preferably 45 to 65 wt%. If the mixing ratio of the cellulose multifilament is less than 15 wt%, the hygroscopicity required as the fabric directly contacting the skin is insufficient. When it exceeds 85 wt%, the fabric adheres to the skin at a large amount of sweating, causing discomfort, and texture change is likely to occur due to repeated washing.

The total fineness of the composite crimping work needs to be 44 to 333 dtex. The more preferable range depends on a use, 167-333 dtex is preferable for outerwear use, 167-278 dtex is preferable for a t-shirt use, 111-200 dtex is preferable for a use in men's wear, 44-167 for women's underwear dtex is preferred. If the total fineness of the composite crimping machine is less than 44 dtex, it is a fabric that directly touches the skin and lacks the necessary sweat treatment function. When it exceeds 333 dtex, it becomes thick and cannot get comfort, and skin texture is also easy to worsen.

The single yarn fineness of a cellulose multifilament is 0.1-5.6 dtex, More preferably, it is 2.8 dtex or less, More preferably, it is 1.4 dtex or less. If the single yarn fineness of the cellulose multifilament exceeds 5.6 dtex, the skin feel worse.

The single yarn fineness of the synthetic fiber multifilament is 0.1-5.6 dtex, Preferably it is 2.2 dtex or less, More preferably, it is 1.4 dtex or less. If the single yarn fineness of the synthetic fiber multifilament exceeds 5.6 dtex, the texture of hand contact and the texture of contact with the skin may be deteriorated, and fabrics having sufficiently small skin irritation may not be obtained. In addition, when the cellulose multifilament single yarn and / or the composite fiber multifilament single yarn are 1.4 dtex or less, it is preferable to use a yarn oil having good openability and good flammability so as to prevent the single yarn from converging at the time of blending. desirable. For example, it is preferable to make the fluid pressure weak and feed rate low as mixing conditions. The fluid pressure is preferably 4.9 × 10 ⁴ to 2.0 × 10 ⁵ Pa, and the feed rate is preferably 0.1 to 2.0%.

The crimp extension rate of the composite crimping work exceeds 4.0% and is 35% or less, preferably 8.0-25%, and more preferably 10-25%. If the crimp elongation is less than 4.0%, the sweat treatment function and elasticity are insufficient, and if it exceeds 35%, the skin irritation becomes a strong cloth. If the crimp elongation is 10% or more, a fabric having a particularly high sweat treatment function and sufficient elasticity can be obtained. Particularly, in the range of 10 to 25%, the fabric directly touches the skin, and the sweat treatment function is sufficiently high, the elasticity is sufficient, the skin texture is good, and the skin texture is very low. As a feeling when using a cloth, a pleasant feeling can be obtained remarkably.

As a cellulose multifilament used for this invention, the cellulose filament which consists of a copper ammonia method rayon (cupra), a viscose rayon, a polynodic rayon etc. is mentioned, for example.

The spinning method of cellulose multifilament is not limited, It can obtain by well-known methods, such as the hank method, the cake method, the spool method, the net process method, and the continuous method. Moreover, you may use combining these 2 or more types. Of these, the cellulose multifilament spun by the net process method is weak in the procedure between the cellulose filament single yarns, so that fluid entanglement makes it easier to entangle the combined filament multifilaments more uniformly. It is preferable because the fabric can be obtained and the curing of the texture in washing can also be suppressed. In addition, since the cellulose multifilament spun by the net process method has high yarn elongation, the range of conditions that can be set in flammable crimping is wide, and the flammable tension can be increased. This high complex crimping work can be obtained.

The cellulose multifilament may be used by containing a gloss removing agent such as titanium oxide or various known additives depending on the purpose.

Examples of the synthetic fiber multifilament include filaments made of polyethylene terephthalate, polybutylene terephthalate, polytrimethylene terephthalate, atmospheric salt type polyester, polyamide, polyolefin, polyacrylonitrile, or copolymers thereof.

The spinning method of these synthetic fiber multifilaments is not particularly limited, and for example, unstretched yarn wound at a winding speed of about 1500 m / min, semi-stretched yarn is used as it is, and unstretched yarn or semi-stretched yarn is about 2 to 3.5 times longer ( I) by a known method such as a method of straightening, a straight-line method in which spinning and a rolling process are directly connected, and a high-speed spinning method with a winding speed of 5000 m / min or more.

The cross-sectional shape of the single yarn of the synthetic fiber multifilament yarn is not particularly limited, and is circular, flat, triangular, L, T, Y, W, π, cross, well, eight lobes, and eight I) Polygonal, multi-lobed, one-hole hollow, plural-hole hollow, or indeterminate, such as molds, spectacles, spectacles, two-hole hollow, dog bone, etc., or may be mixed. . Among these, Y type, W type, cross type, well type, spectacle type, spectacle type two-hole hollow, L type and the like are preferable because of excellent wicking property and high water absorption by capillary action. In addition, cross-sectional shapes having a small bending Young's modulus such as annular flat yarns, W-shaped flat yarns, spectacle flat yarns, spectacle two-hole flat yarns, and π-flat flat yarns are preferable because of their low frictional irritation to the skin. W type flat yarns, spectacle flat yarns, spectacle two-hole flat yarns, and π flat yarns are particularly preferred as a combination of sweat absorption and low friction irritation to the skin.

In composite crimping, the area (S) of the overlapping area of the dispersed area of the cellulose multifilament single yarn and the dispersed area of the synthetic fiber multifilament single yarn occupies the area (SG) of the dispersed area of the synthetic fiber multifilament single yarn (30). It is preferable that it is 95%, More preferably, it is 50 to 95%. The mixing degree of the cellulose multifilament single yarn and the synthetic fiber multifilament single yarn may be 30% or more, and the absorption rate is improved to provide comfort. Particularly, if it is 50% or more, very fast absorption speed can be obtained without prescribing an absorbent in the dyeing and finishing process of the fabric.

In addition, the dispersion area of the multifilament single yarn means the area | region in which the said filament single yarn is disperse | distributed in the cross section of the thread strand of the composite crimping work in which other multifilament was mixed.

Next, although the manufacturing method of the composite crimping process of this invention is demonstrated, as long as the composite crimping process which can achieve the objective of this invention can be obtained, it may be manufactured by what kind of method, for example, a mixed fiber and a flammable Either may be first, and the manufacturing method is not limited.

As a mixing method of a cellulose multifilament yarn and a synthetic fiber multifilament yarn, the method of opening and interweaving by the air interlocking method called interlace, the electro-opening method by electrostatic force, is mentioned, for example. In the present invention, the cellulose multifilament single yarn and the synthetic fiber multifilament single yarn need to be at least continuously entangled with each other, and these filament single yarns are mixed uniformly as long as they can be mutually single yarns without being converging alone. It is preferable to be in the state containing air between each single yarn, without sticking.

In the case of the interlacing method, the number of entanglements is preferably 20 or more and 120 or less per yarn length in terms of uniform mixing. More preferably, they are 70 or more and 120 or less. If the number of entanglements is less than 20, single yarns may not be uniformly mixed. When the number of entanglements exceeds 120, the swelling of the yarn is reduced, and the sweat treatment function tends to be lowered, and the skin texture is also hard, which tends to increase skin irritation.

In addition, the combustion method for imparting crimping is not particularly limited as long as it is combustible and can be heated in the flammable area, and generally used belt nipper type, pin type, precushion type, air combustion type and the like can be used. Can be.

Although flammable processing may be before the said mixed island entanglement, in order to perform a more uniform blended island, it is preferable to perform a mixed island entanglement first, and then perform a combustion. In addition, if the twisting is performed in a belt nipple manner after the interweaving, the thread strands are twisted in the twisting step, and thus, the cellulose single yarn and the synthetic fiber single yarn are more uniformly mixed.

Moreover, productivity is preferable when using the apparatus which can make a mixed island entanglement and a combustible continuous.

Moreover, it is preferable to use the winding after a process with a tension of 0.08 cN / dtex or less so that the structure of a composite crimping process may not be broken.

Two examples which are preferable as a process of a manufacturing method are demonstrated.

The first example is to burn after mixing the cellulose multifilament and the synthetic fiber multifilament with air entanglement. In this case, the preferred ranges of the feed rate and interlace pressure vary depending on the type of cellulose multifilament yarn, the type of synthetic fiber multifilament yarn, the specifications of the apparatus, and in particular the shape of the interlace nozzle for air entanglement. 5% is preferable and 0.5-2.0% is more preferable. Moreover, 4.9 * 10 <^4> -4.9 * 10 <^5> Pa is preferable and, as for an interlace pressure, 9.8 * 10 <^4> -2.0 * 10 <^5> Pa is more preferable.

When the feed rate exceeds 5%, the processing tension fluctuates, so that uniform mixing may not be performed. In the case of a feed rate lower than 0.1% or underfeed, interlace entanglement may become inadequate and the functionality, such as a cloth absorbency, may fall. When the interlacing pressure exceeds 4.9 x 10 ⁵ Pa, fluff may occur in the cellulose filament or the catch of flamming may be poor, resulting in a thinner finish yarn, which may lower the sweat treatment function of the fabric. When the interlace pressure is less than 4.9 × 10 ⁴ Pa, the interlace entanglement is insufficient and the functionality of the fabric may be lowered.

The nozzle shape of the interlace is preferably a shape in which air is injected at an angle of 85 degrees or less with respect to the traveling direction of the yarn in order to uniformly obtain a composite crimping work that satisfies the problem of the present invention.

The combustion conditions in the subsequent combustion process depend on the melting point of the synthetic fiber multifilament, the heater specification and the processing speed of the processing machine, but the heater temperature before combustion is preferably 100 ° C to 190 ° C, more preferably 120 ° C to 190 ° C, More preferably, they are 150 degreeC-180 degreeC. If the heater temperature before burning is less than 100 ° C., sufficient crimping is difficult to be obtained. At high temperatures exceeding 200 ° C., the cellulose single yarn is hardened, the skin feels gritty, and skin irritation may increase. In addition, the flammable method is preferable because the belt knife method easily mixes the cellulose multifilament and the synthetic fiber multifilament with each other, thereby making it easy to obtain a high-capacity composite crimping process. The stretching ratio of the combustion process is preferably carried out in the 0 to 5% overfeed region for stable production. More preferably, it is 0 to 2% of overfeed area.

In order to stably obtain a composite crimping work that satisfies the problems of the present invention, the tensile strength is preferably 0.16 to 0.27 cN / dtex, and the seam tension is preferably 0.07 to 0.27 cN / dtex. The number of twists is [(23000 / B ^1/2 ) + 590] × 0.80 (times / m) or more, and [(23000 / B ^1/2 ) + 590] × 0.95 (times / m) or less to solve the problems of the present invention. It is desirable to achieve. In addition, B = (dtex) × 9/10 in the above.

A second preferred example is the method of first only burning the synthetic fiber multifilament and then mixing the combusted synthetic fiber multifilament with the cellulose multifilament. Although the flammability conditions of the synthetic fiber multifilament depend on the melting point of the synthetic fiber multifilament, the heater temperature before combustion is preferably 100 ° C to 220 ° C, more preferably 120 ° C to 190 ° C, and even more preferably 150 ° C to 190 ° C. to be. When the heater temperature before combustion is less than 100 ° C., sufficient crimping is difficult to obtain. It is also preferable to use the set heater after burning, since the skin tends to have less skin irritation. The set heater temperature is preferably 100 ° C to 190 ° C. The draw ratio of the combustion process is preferably 0.95 to 1.05 for stable production.

The number of twists is [(23000 / B ^1/2 ) + 590] × 0.70 (times / m) or more and [(23000 / B ^1/2 ) + 590] × 1.0 (times / m) or less to solve the problems of the present invention. It is desirable to achieve. In addition, B = (dtex) × 9/10 in the above.

Preferred ranges of feed rate and interlacing pressure as intermixing conditions of combustible multifilament and cellulose multifilament combusted in the subsequent blending process include the type of cellulose multifilament yarn, the type of synthetic fiber multifilament yarn, the specification of the device, in particular the nozzle of the interlace for air entanglement. Although it changes with a shape, 0.1-5% is preferable and, as for the feed rate of a cellulose multifilament, in an overfeed area | region, 0.5-2.0% is more preferable. In addition, in order to obtain a fabric having an excellent sweat treatment function, it is preferable to make the feed rate of the synthetic fiber multifilament 0.1 to 5% larger than the feed rate of the cellulose multifilament. Moreover, 4.9 * 10 <^4> -4.9 * 10 <^5> Pa is preferable and, as for an interlace pressure, 9.8 * 10 <^4> -2.0 * 10 <^5> Pa is more preferable.

When the feed rate of a cellulose multifilament exceeds 5%, processing tension may not be stabilized and uniform mixing may not be performed. In the case where the feed rate is less than 0.1% or underfeed, the interlace entanglement may be insufficient, resulting in deterioration of functionality such as absorbency of the fabric. When the interlacing pressure exceeds 4.9 x 10 ⁵ Pa, fluff may occur in the cellulose multifilament or the catch of flamming may be poor, resulting in a thinner finish yarn, thereby lowering the sweat treatment function of the fabric. When the interlace pressure is less than 4.9 × 10 ⁴ Pa, the interlace entanglement is insufficient and the functionality of the fabric may be lowered.

The knitted fabric used in the present invention preferably has a coefficient of friction at wetting of 3.0 or less, more preferably 2.0 or less, which is an indicator of the adhesion of the cloth to the skin. If the coefficient of friction during wetting of the knitted fabric exceeds 3.0, the feeling of sticking and wetness of the fabric to the skin at the time of sweating may increase, resulting in an increase in discomfort. In addition, if the coefficient of friction at the time of wetting is 2.0 or less, the sticking feeling and the wet feeling become smaller, and as a feeling when using the cloth, it can be felt remarkably comfortable.

In addition, the knitted fabric used in the present invention has a SB value, which is a measure of the refreshing feeling under the sweaty situation defined by the following formula (2), satisfies the following formula (1) and is defined by the following formula (4): It is preferable that SN value which is a measure of the refreshing feeling in a flowing situation satisfy | fills following formula (3).

0.0 <SB <100.0... … (One)

SB = 1.08 x (heat dissipation) + 1.98 x (surface irregularities) + 6.25 x (surface friction coefficient)-13.92. … (2)

0.0 &lt; SN &lt; 100.0 … (3)

SN = -0.03 × (quantity) + 1.42 × (humidity progression) + 0.17 × (heat dissipation) + 0.76 × (surface irregularities) + 12.1 × (surface friction coefficient)-16.6. … (4)

In other words, if the SB value which is a measure of the refreshment feeling in the degree of sweating and the SN value that is the measure of the refreshment feeling in the degree of sweating are greater than 0 and less than 100, the sweat is used when the fabric is used. In this situation, the degree of cooling and the flow of sweat are excellent in both the comfort and comfort can be obtained. When the product of the SB value and the SN value is 0.5 or more, the refreshing feeling is further excellent.

The SB value and the SN value are derived from the following tests by the present inventors as a measure of the refreshing feeling.

That is, a number of fabrics having different types of fibers, fiber structures, combinations of fibers, types of knitted fabrics, knitted fabrics, etc. were fabricated, sewn them as underwear for upper body, and a wear test was conducted to extract factors of cooling sensation. . Specifically, a large number of wear testers were selected to hide the details from the wear testers and distribute the test-produced garments to be repeated daily for one point over a long period of time, and to evaluate the factors of 18 items related to the refreshing feeling. Every time it was worn. As a result, in the case of sweating, the non-sticky, sweat-free, and soft skin texture became the three criteria of freshness judgment, but not sweaty in the flowing situation, The fact that the cloth does not stick to the skin and the heat does not occupy other than the sweat does not become a criterion of judgment, and it became clear that the ranking of the importance of the skin texture item is lowered.

Subsequently, the physical properties of the knitted fabrics tested for wear were measured for 43 items at all angles such as physical properties of water, physical properties of humidity, physical properties of heat, physical properties of surface shape, physical properties of texture, and fabric deformation degree. By analyzing the relationship with the sensory evaluation results, the physical properties of the cloth contributing to the freshness and its importance are identified, and the SB value is defined by the above equation (2) and the SN value is defined by the above equation (4) as a measure of the freshness.

In said Formula (2) and (4), the heat radiation amount (W / m <2> * degreeC) means the ability to discharge | release heat in clothing outside, and a preferable range is 10-15 W / m <2> * degreeC. Surface unevenness | corrugation means the unevenness | corrugation degree of the cloth which contacts skin surface, and a preferable range is 0.2-1.5. Surface friction coefficient refers to the slippery property of the cloth which contacts skin, and the preferable range is 0.20 to 0.35. Yield amount (%) means the property which the sweat which cloth absorbed is hard to return to skin, and a preferable range is 0 to 50%. Humidity performance degree refers to the ability to release moisture in clothing to the outside, and the preferred range is 10.0 to 11.0. These can be measured by the method of mentioning later.

In addition, in the present invention, it is preferable that the skin irritation index is 8.0 μS or less when drying the knitted fabric, and when the skin irritation index exceeds 8.0 μS, the physical frictional stimulus to the stratum corneum increases, so that the skin is sensitive to the season. Itching or redness may occur.

The skin stimulation index is an index indicating the degree of skin irritation caused by 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 uses the phenomenon that keratin moisture increases by peeling keratin by physical stimulus caused by friction, and the inner layer part of keratin comes out to the skin surface. The amount of change in moisture is measured as electric admittance (Siemens [S]). In addition, the detail of a measuring method is mentioned later.

In addition, when the fabric is composed of a knitted fabric, it is excellent in elasticity and elastic recovery, has no restraint during operation during wearing, and is easy to move. It is preferable that the elongation stress at the time of% elongation is 20 cN / cm or less, More preferably, it is 15 cN / cm or less, and it is preferable that the elongation stress at the time of 80% elongation of a knit transverse direction is 20 cN / cm or less. More preferably, it is 1-15 cN / cm width. In addition, it is preferable that the elongation recovery rate at the time of 50% elongation of a knit longitudinal direction is 80% or more, More preferably, it is 85-100%, and the elongation recovery rate at the time of 100% elongation of a knit transverse direction is 80% or more. More preferably, it is 85 to 100%.

The knitted fabric of the present invention preferably has a mass per unit area of 80 to 250 g / m 2, more preferably 80 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, it may be too heavy and the fit may worsen.

In the present invention, the method for making a composite crimped fabric into a knitted fabric or a woven fabric is not particularly limited and can be produced using a common knitting or loom. It is also possible to interweave with other materials such as spandex, synthetic fiber, cotton and silk.

Knitted fabrics include price, smooth, sheeting, greens, squadrons, pontiroma, Milan ribs, pearl knitting, etc., various types of transverse knitting, tricot tissues such as half-trees, two-way, double denby and atlas, and satin nets. , Russell tissue such as triconnet, weft insertion tissue can be used. Moreover, although the structure of these changes is also possible, and it can select suitably according to the objective, it is preferable to set it as the knitted structure which is comparatively coarse in density, and excellent in elastic force.

For example, in the case of a smooth structure, it is preferable that the loop length (L) (cm) of the nose constituting the knitted fabric and the total fineness (D) (dtex) of the composite crimping work satisfy the following formula (5), More preferably, the following formula (6) is satisfied.

2.9 (cm) ≤ (L / D ^1/2 ) x 100. … (5)

3.8 (cm) ≤ (L / D ^1/2 ) x 100. … (6)

In the case of the price structure, it is preferable that the loop length (L) (cm) of the nose constituting the knitted fabric and the total fineness (D) (dtex) of the composite crimping work satisfy the formula (7), and more preferably Equation (8) is satisfied.

2.1 (cm) ≤ (L / D ^1/2 ) x 100. … (7)

3.1 (cm) ≤ (L / D ^1/2 ) x 100... … (8)

In the case of the sheet tissue, it is preferable that the loop length (L) of the nose constituting the knitted fabric and the total fineness (D) (dtex) of the composite crimping work satisfy the formula (9).

2.1 (cm) ≤ (L / D ^1/2 ) x 100. … (9)

When the said tissues do not satisfy | fill Formula (5), (7), and (9), respectively, there exists a case where sweat processing function and heat retention are insufficient.

Examples of the knitted fabrics include knitting, twill weaving, runners and their changing organizations.

The processing method of the knitted fabric or the woven fabric used in the fabric of the present invention is not particularly limited, and dyeing may be carried out in addition to whitening by fading and bleaching finishing.

For example, any method may be used, such as a dyeing method performed in the state of yarns such as tecil or cheese, that is, a dyeing method performed in the state of a composite crimping process, a knitting or a fabric, or as a dye, a dyeing aid, or a finishing agent. Generally what is used for dyeing the synthetic fiber and / or cellulose fiber marketed can be arbitrarily selected according to the objective. It is also possible to use a fluorescent brightener arbitrarily. In dyeing or knitting fabrics or fabrics, pretreatment such as refining, fading / bleaching, alkali treatment for improving the dyeability of cellulose fibers, and alkali reduction carried out with polyester fibers may be performed.

In addition, the finishing set is preferable because it provides a fabric having a soft texture and excellent skin irritation and a sweat treatment function. If the set effect is too strong, the crimp of the composite crimping work in the fabric may be damaged, resulting in deterioration of the sweat treatment function and elasticity.

If the set temperature is too high, the cellulose multifilament in the fabric may be hardened, resulting in a hardened texture or a stronger skin irritation. Specifically, in the case of the wet heat set method, the texture may be cured under a set condition of 180 ° C for 1 minute or more, and in the dry heat set method, the texture may be cured under the set condition of 190 ° C for 1 minute or more.

Hereinafter, the present invention will be described in detail by way of examples. In addition, each evaluation value in the example was measured by the following method.

(1) Friction coefficient when wet

A KES-FE precushion tester (hereinafter referred to as a friction tester) manufactured by Katotech Co., Ltd. is used.

An acrylic plate (size: 8-12 cm, thickness 5 mm) is placed on the sample table of the friction feeling tester, and fixed with a tape or the like. The mass of the sample (5 cm in the longitudinal direction of the knitted fabric and 3 cm in the transverse direction) is measured.

A 25 cm long yarn (Shibobo Co., T span 60) is sewn to a position of about 1 mm from the end over the entire end on one short side of the sample. At this time, take care that the sample comes to the center of the yarn.

Water (0.4 ml) is sprayed substantially evenly with a simple atomizer used when ironing the sample and left for 1 minute to spread the water evenly throughout the sample. The wetted sample is placed on the acrylic plate in such a manner that the direction of operation of the friction tester and the long side of the sample (the longitudinal direction of the knitted fabric) are aligned so that the short side where the thread is stitched is the sensor side.

Both ends of the stitched part of the yarn sewn to the sample are attached to the scroll of the sensor of the friction tester.

EMBODIMENT OF THE INVENTION Hereinafter, this invention is demonstrated in detail.

First, the sweat absorption mechanism of the fabric directly in contact with the skin will be described.

The following five factors are important to prevent the skin from sticking when sweating or sticking to the skin.

First, it is important to absorb sweat on the skin as quickly as possible. Second, if sweat continues, the cloth continues to absorb sweat, eventually exceeding the allowable amount of water retained by the cloth, and a water film is generated on the surface of the cloth (hereinafter, the amount of water repair at the time the water film starts to occur). Limit), sweat remains on the skin and the fabric itself sticks to the skin. In order to prevent this, it is important that the fabric has a high water-holding limit and is more than the range of sweating when worn. Third, when pressure is applied by the operation, it is important that the absorbed sweat does not bleed on the surface of the cloth even if the cloth is compressed and deformed. When the cloth is compressively deformed and the void is crushed by pressure, the void water is easy to bleed out, but the bound water is difficult to bleed. Fourth, when the wearing situation is viewed over time, high quick-drying has the effect of substantially increasing the water retention limit. Fifth, when the amount of sweating is very large, it is important to reduce the water retention limit and to reduce the area where the meninges come into contact with the skin after the meninges have formed on the surface of the fabric.

The amount of water retained by the fabric is the sum of the amount of water retained as the binding water in the fibers and the amount of water retained in the voids between the fibers.

In the knitted fabric or woven fabric (hereinafter sometimes referred to simply as knitted fabric or the like) used in the fabric of the present invention, a composite crimping fabric in which cellulose multifilament and synthetic fiber multifilament are mixed and at least one of them is combustible is used. As the knitted fabric or woven fabric used in the fabric of the present invention, this composite crimping work may be used at least in part, and examples thereof include knitted or woven fabrics interlaced with other textile materials.

In the present invention, the composite crimping work has a structure in which the cellulose multifilament and the synthetic fiber multifilament are mixed by dispersing the single yarn arrays from each other, and have a large amount of voids in the yarn strands by the crimping. In this case, at least one of a cellulose multifilament and a synthetic fiber multifilament should just be flammable. When both are flammable, the cellulose multifilament single yarn has a relatively weak crimp, and the synthetic fiber multifilament single yarn tends to have a relatively strong crimp. In addition, since it becomes a structure in which many cellulose multifilament single yarns exist in a center part, it is preferable.

For this reason, according to the fabric of the present invention, the excellent hygroscopicity of the cellulose multifilament provides comfort that is hard to sweat even on high humidity days, and the moisture absorbed by the sweat is maintained as the binding water of the cellulose multifilament. In addition, in the case of a knitted fabric, a large amount of water can be maintained as void water in the voids between the single yarns increased by the crimping processing of the processed yarns, and the repair amount limit is greatly increased.

In addition, since sweat is retained even as the binding water of cellulose, sweat is hard to escape from the cloth even when a pressure is applied. In addition, since the cellulose multifilament and the synthetic fiber multifilament are mixed with each other, the diffusion rate in the thread and the fabric of the sweat is high due to the interaction, and as a result, the drying speed of the fabric is high, resulting in a higher practical repair amount limit. . In addition, the sweat absorbed from the skin surface gradually shifts to the central portion of the thread strand over time and is ubiquitous, and protrudes in a gentle curved shape from the thread strand surface, and the presence of a small amount of hydrophobic synthetic fiber multifilament single yarn that has been repaired A spacer effect occurs between the skin and the moisture inside the thread strands to prevent sticking to the skin.

The crimp elongation rate is an index of crimp strength in the composite crimping work used in the present invention, and is very deeply involved in various functionalities as a fabric directly touching the skin, which is the subject of the present invention. That is, the greater the crimp extension, the higher the stretchability of the fabric. In particular, in the case of composite crimping, the crimping elongation rate is reflected in the strength of the disturbance of single yarn arrangement of cellulose multifilament single yarn and composite fiber multifilament single yarn, the mixing strength of single yarn, and the amount of voids in the yarn strand of composite crimping. For this reason, if the crimp extension rate of the composite crimping work is too small, the sweat treatment function by the above mechanism is not achieved. In addition, in the case of composite crimping, the crimp extension rate reflects the strength of the single yarn arrangement of the synthetic fiber multifilament single yarn as described above, and if the crimp extension ratio is too high, the skin irritation becomes stronger due to the physical stimulation caused by the synthetic fiber multifilament single yarn. In addition, the touch to the skin and the touch to the hand also tend to be worse.

In the composite crimping work used in the present invention, the area S of the overlapping area of the dispersion area of the cellulose multifilament single yarn and the dispersion area of the synthetic fiber multifilament single yarn occupies the area SG of the dispersion area of the synthetic fiber multifilament single yarn ( A) is an indicator of the mixing degree of cellulose multifilament single yarn and synthetic fiber multifilament single yarn, and is strongly involved in the sweat treatment function. That is, as A increases, the synthetic fiber multifilament single yarn and the cellulose multifilament single yarn are uniformly mixed, so that the absorption rate is improved. Especially, when A is 50% or more, the absorption rate is remarkably improved, and sufficient absorption rate can be obtained without prescribing an absorbent agent in the salt finishing process of the fabric.

In addition, since the composite crimping work used in the present invention is made of filaments, the friction between the yarn and the yarn is smaller than that of the spun yarn, and does not prevent the tissue deformation of the knitted fabric. For this reason, the fabric of this invention can obtain the underwear which is excellent in elasticity and elastic recovery. Moreover, since it is a knitted fabric which consists of filaments, the slipperiness | lubricacy of a surface is good and also slipperiness with outerwear clothing is good also when the outerwear is piled up. As a result, it is not stiff even when overlapped, there is no restraint at the time of operation, and the comfort feeling excellent in the adhesiveness to a body can be obtained.

In addition, cellulose multifilament is an excellent material having low skin irritation. Although this is a raw material property of cellulose, the present invention also derives from the morphological properties of the filament, and since there are few yarn ends seen in the spun yarn in the knitted fabric, the skin irritation property is further lowered. However, in the fabric of 100% of cellulose multifilament, the filament tends to be converged by repeated wet and dry during repeated washing, and the fabric may be hardened to increase skin irritation. By combining, the convergence property of a cellulose multifilament can be suppressed, and skin irritation can be kept low even if washing is repeated.

In the fabric of 100% cellulose multifilament, stickiness to the skin occurs at a large amount of sweating, and if the skin is wet, physical stimulation may be applied to damage the stratum corneum, but in the fabric of the present invention, the synthetic fiber multifilament It is separated into single yarns by intermixing twisting, and is expressed on the surface of the thread strand of the composite crimping work in a gentle curved form (approximate to the sign curve) between cellulose multifilament single yarns. For this reason, in the state where no pressure is applied, the ratio of the haptic multifilament to the skin is higher than that of the cellulose multifilament to the skin first, but when the sweating effect (the spacer effect by the synthetic fiber multifilament) is combined, Skin irritation decreases.

That is, in 100% of cellulose, the skin irritation index when wetted by fabrics due to sweating, etc., becomes very large compared to the skin irritation index when dried, but the synthetic skin irritation index and wet skin irritation by drying The difference between the indices can be kept small, and soft undergarments can be obtained for the skin with less skin irritation during drying and wetting.

In addition, by using a yarn having excellent cross-sectional shape as absorbing (wicking property due to capillary phenomenon), such as W-shaped cross-sectional flat yarn, spectacle flat flat yarn, π-shaped cross-sectional flat yarn, cross-shaped cross yarn, and the like, as described later as a synthetic fiber multifilament In addition, the absorption rate into the fabric increases, and the diffusibility of the sweat cloth increases, and as a result, the quick drying property can be improved. In other words, it is possible to quickly absorb sweat on the skin and to obtain a fabric having excellent quick drying property.

The fabric of the present invention only needs to have the knitted fabric or fabric, and includes at least part of the fabric having the knitted fabric or fabric.

The fabric in the present invention refers to a fabric directly in contact with the skin, for example, it can be used suitably for use in direct contact with the skin, such as clothing, bedding, towels, handkerchiefs.

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

Examples of the ladies' lingerie include camisole, slip, patty coat, flared pants, body briefs, teddy, and the like. Examples of women's foundations include underwear garments with body correction effects such as bras, girdle and body suits.

In addition, the fabric of the present invention is suitably used as a bedding of a sheet, a blanket, a pillow cover, etc., in which the fabric directly touches the skin for a long time and sweat absorption is required. Moreover, it can use suitably also as towel and handkerchief.

The fabric of the present invention has good sweat absorption when used in direct contact with the skin, for example, as a garment, and there is no sticky feeling or unpleasant feeling of clothing sticking to the skin even when a large amount of sweat occurs in daily life, and hygroscopicity It is excellent and has a low sweating feeling, has a refreshing feeling on hot days in summer, and is warm with a soft skin texture on cold days in winter. In addition, it has excellent elasticity and slipperiness, so there is no restraint during operation, it is comfortable to wear, soft to the skin, small physical friction stimulus to the skin, and it is soft to the skin even after wearing it and maintains the beautiful appearance of the filament.
