Description

  The present invention relates to a knitted fabric for clothing excellent in heat retention and moisture absorption.

  Conventionally, products for inner use have been demanded to be thin and light from the viewpoint that they are not bulky and are not easily noticeable on the outer. On the other hand, it is generally considered that a material having high heat retention is thick and a material having a thin dough has poor heat retention. In the past, there were no products with conflicting properties such as high heat retention even though the fabric was thin and light.

  So far, many studies have been made to increase the heat retention in clothing fabrics worn in autumn and winter. Representative means include those using hygroscopic exothermic fibers, those using acrylic fibers, and those applying yarn shrinkage after dyeing.

  In addition, many studies have been made to make the fabric hygroscopic in order to reduce the feeling of stuffiness in clothes when worn. Typical means includes a hygroscopic exothermic fiber and a fiber blended with cellulose fiber. For example, a spun yarn obtained by blending a hydrophobic synthetic fiber having a fine single yarn fineness and a hygroscopic exothermic fiber has been proposed (see Patent Document 1). This spun yarn is not satisfactory in terms of heat retention, although the fabric is hygroscopic by using hygroscopic exothermic fibers. In other words, polyester with low thermal conductivity is used for hydrophobic fibers, and the single yarn fineness is reduced to reduce the size of the gap between the fibers. Even if the effect that it is difficult to escape is obtained, the heat retention is not improved.

  Further, an acrylic spun yarn in which acrylic fiber and regenerated cellulose fiber are mixed is proposed (see Patent Document 2). Although this spun yarn uses acrylic fibers with high heat retention, there is no great difference in heat retention compared to conventional acrylic / cellulose fibers.

  In addition, a spun yarn obtained by blending ultrafine acrylic short fibers, highly shrinkable acrylic short fibers, and polyester short fibers has been proposed (see Patent Document 3). This spun yarn has high heat retention by making it high density using high shrinkage yarn, but there is a problem that the knitted fabric becomes heavy, and it is difficult to obtain thinness and lightness.

  On the other hand, in addition to the basic functions of heat retention required for recent autumn and winter clothing, comfort performance such as texture and comfort has been demanded. In particular, there is a need for inner materials that are warm but not bulky, and that do not stand out on the outerwear. In addition, as a result of the investigation, it was found that in mid-winter, when you enter a warm room with thick clothes from the cold outdoors, your body often feels hot and uncomfortable. Accordingly, the present invention provides a knitted fabric for clothing, in particular an inner knitted fabric, which realizes the aforementioned light, thin and warm performance in order to maintain a comfortable wearing feeling even under such environmental changes, while reducing the feeling of stuffiness without impairing the performance. The purpose is to provide the most suitable knitted fabric for the customer.

  As a result of diligent studies to achieve the above object, the present inventors first used a spun yarn containing acrylic fiber having a single yarn fineness difference, thereby giving the fiber a difference in shrinkage or strong crimping. It was found that light, thin and warm performance, which is highly demanded for winter clothing, can be achieved without using a product with a high profile. In addition, this spun yarn can be mixed with specific hygroscopic fibers to achieve a light, thin and warm knitted fabric, as well as to improve the above-mentioned stuffiness caused by environmental changes by absorbing gas-phase sweat. As a result, the present invention has been completed.

That is, the present invention is a hygroscopic fiber A having a moisture content of 7% or more and less than 13% at 20 ° C. × 65% RH, acrylic fiber B having a single yarn fineness of 0.3 to 0.7 dtex, and 0.8 to A blended yarn containing 10 to 60% by weight, 20 to 75% by weight, and 10 to 40% by weight of acrylic fibers C having a single yarn fineness of 2.0 dtex, respectively, and the total of the fibers B and the fibers A and C; Is a weight ratio of 2: 8 to 8: 2, the single yarn fineness difference between the fiber B and the fiber C is 0.3 to 1.7 dtex, and the blended yarn having 55 to 100 counts is 40% by weight. for the use above a thickness is 0.5 to 1.2 mm, it basis weight is 120~160g / ^{m 2,} and the knitted fabric of the moisture content is 3 to 25% specific volume 3~10cc / G and a knitted fabric characterized by a heat retention rate of 15 to 35% .

Preferred embodiments of the knitted fabric of the present invention are as follows.
(I) Highly hygroscopic fibers having a moisture content of 13% to 30% of the hygroscopic fibers A in the blended yarn are contained in an amount of 5 to 30% by weight with respect to the blended yarn.
(Ii) The inter-fiber porosity in the cross section of the blended yarn is 30 to 60%.
(Iii) The acrylic fiber having 18 to 40% bulky property among the acrylic fibers C in the blended yarn is contained in an amount of 10 to 40% by weight based on the blended yarn.
(Iv) friction Kosu耐voltage is 0～3000V, a half-life of 0-30 seconds.

  Even if the knitted fabric of the present invention is light and thin, it is warm when worn and feels good (feel). Moreover, the inner fabric can be made inconspicuous from the outside of the outer garment by not being bulky, and in addition, the stuffiness that tends to occur after moving from the outdoors in the winter to a warm room is reduced. Therefore, the knitted fabric which has the performance calculated | required for the fall / winter clothing material, especially inner use can be provided suitably.

The knitting structure of Example 1 is shown. The knitting structure of Example 2 is shown. The cross-sectional photograph of the blended yarn of Example 1 is shown. The cross-sectional photograph of the blended yarn of Example 2 is shown. The cross-sectional photograph of the blended yarn of the comparative example 7 is shown.

  The blended yarn used in the knitted fabric of the present invention is a hygroscopic fiber A having a moisture content of 7% or more and less than 13% at 20 ° C. × 65% RH (relative humidity), single yarn fineness of 0.3 to 0.7 dtex. 10 to 60% by weight, 20 to 75% by weight, and 10 to 40% by weight of an acrylic fiber B having a single yarn fineness of 0.8 to 2.0 dtex, respectively. And the weight ratio with the sum total of C is 2: 8-8: 2.

  As the hygroscopic fiber A used for the blended yarn of the present invention, any fiber can be used as long as the moisture content at 20 ° C. × 65% RH is 7% or more and less than 13%. For example, natural fiber cotton, silk, hemp, regenerated cellulose fiber rayon, cupra, tencel, lyocell, etc., but rayon is used from the viewpoint of fine fiber production, dyeability necessary for clothing, and texture. Is preferred. Further, in the hygroscopic fiber A, a highly hygroscopic fiber having a moisture content of 20 ° C. and 65% RH of 13% to 30% may be mixed. As a highly hygroscopic fiber, a hydrophilic functional group can be added to a general purpose fiber using a technique such as grafting a hydrophilic monomer such as acrylic acid or methacrylic acid to the fiber, or replacing acrylonitrile of the acrylic fiber with a hydrophilic functional group. And a highly hygroscopic fiber having a moisture content of 20 ° C. and 65% RH of 13% to 30%. The highly hygroscopic fiber may be a natural fiber, and examples thereof include wool, modified rayon, modified cotton, and acrylate.

  The mixing ratio of the hygroscopic fiber A in the blended yarn of the present invention is 10 to 60% by weight, and preferably 30 to 50% by weight. When the mixing ratio is less than the above range, the moisture content of the knitted fabric is low and the moisture absorption performance is lowered, so that the feeling of stuffiness during wearing is not reduced. On the other hand, if the above range is exceeded, the consumption performance such as pilling is reduced when the garment is made. Further, when the highly hygroscopic fiber is mixed with a part of the hygroscopic fiber A, the mixing ratio of the highly hygroscopic fiber is 5 to 30% by weight, preferably 10 to 25% by weight with respect to the blended yarn. . If the mixing ratio of the highly hygroscopic fibers exceeds the above range, the mixing ratio of the acrylic fibers B is lowered and the gaps between the fine fibers are reduced, so that the heat retention is not improved.

  The single yarn fineness of the acrylic fiber B used for the blended yarn of the present invention is 0.3 to 0.7 dtex, preferably 0.4 to 0.6 dtex. When the single yarn fineness of the acrylic fiber B is less than the above range, the color density when dyeing is extremely reduced, and it becomes difficult to obtain uniform dyeability of the blended yarn. On the other hand, if the above range is exceeded, the difference in fineness with the acrylic fiber C is reduced, the inter-fiber gap is lowered and the heat retaining property is not increased, and it becomes difficult to spin a spun yarn with uniform fine count. The single yarn fineness of the acrylic fiber C used for the blended yarn of the present invention is 0.8 to 2.0 dtex, preferably 0.8 to 1.3 dtex. When the single yarn fineness of the acrylic fiber C is less than the above range, the difference in fineness from the acrylic fiber B is reduced, and the heat retention is lowered. When the above range is exceeded, it is difficult to spin fine yarn and the texture tends to be hard. The single yarn fineness difference between the acrylic fiber B and the acrylic fiber C is preferably 0.3 to 1.7 dtex, and more preferably 0.5 to 1.6 dtex. If the single yarn fineness difference is less than the above range, fine voids between fibers decrease and heat retention decreases, and if it exceeds the above range, it becomes difficult to spin fine yarn, and it is thin and warm. Spinning yarn cannot be made.

  The acrylic fibers B and C are preferably made of an acrylonitrile-based polymer containing 50% by weight or more of acrylonitrile. The acrylonitrile-based polymer may be an acrylonitrile homopolymer when it contains 50% by weight or more of acrylonitrile, but it is a copolymer of acrylonitrile and an unsaturated monomer copolymerizable with acrylonitrile in terms of economy. A copolymer containing 95% by weight is preferred. If the acrylonitrile content of the copolymer containing acrylonitrile is less than 50% by weight, the characteristics of acrylic fibers such as dyeing clarity and color developability will not be exhibited, and other physical properties such as thermal properties will tend to be reduced. Become.

  Examples of unsaturated monomers copolymerizable with acrylonitrile include methyl acrylate, ethyl acrylate, isopropyl acrylate, n-butyl acrylate, 2-ethylhexyl acrylate, 2-hydroxyethyl acrylate, and hydroxypropyl acrylate. Acrylic acid ester, ethyl methacrylate, isopropyl methacrylate, n-butyl methacrylate, isobutyl methacrylate, t-butyl methacrylate, n-hexyl methacrylate, cyclohexyl methacrylate, lauryl methacrylate, 2-hydroxyethyl methacrylate, methacryl Methacrylic acid ester such as hydroxypropyl acid, diethylaminoethyl methacrylate, acrylic acid, methacrylic acid, maleic acid, itaconic acid, acrylamide, N-methylolacrylamido , Diacetone acrylamide, styrene, vinyl toluene, vinyl acetate, vinyl chloride, vinylidene chloride, vinyl bromide, vinylidene bromide, vinyl fluoride, include unsaturated monomers such as vinylidene fluoride.

  Furthermore, monomers copolymerized for the purpose of improving dyeability and the like include p-sulfophenyl methallyl ether, methallyl sulfonic acid, allyl sulfonic acid, styrene sulfonic acid, 2-acrylamide-2-methylpropane sulfonic acid, and these Alkali metal salts and the like.

  The molecular weight of the acrylonitrile-based polymer is not particularly limited as long as it is within the range normally used for the production of acrylic fibers, but if the molecular weight is too low, the spinnability tends to deteriorate and the yarn quality of the raw yarn tends to deteriorate. If the molecular weight is too high, the polymer concentration that gives the optimum viscosity to the spinning dope tends to be low, and the productivity tends to decrease. Therefore, it is appropriately selected according to the spinning conditions.

  The method for producing the acrylic fibers B and C is not particularly limited. For example, the acrylic fibers B and C can be produced by a wet spinning method in which an acrylonitrile-based polymer containing acrylonitrile in an amount of 85% by weight or more is dissolved in a solvent to form a spinning dope and spin. Examples of the solvent used for spinning include dimethylacetamide, dimethylformamide, dimethylsulfoxide, organic solvents such as ethylene carbonate, propylene carbonate, γ-butyrolactone, and acetone, and inorganic solvents such as nitric acid, sodium rhodanate, and zinc chloride. .

  A part of the acrylic fiber C may be a bulky type acrylic fiber. The knitted fabric of the present invention has sufficient heat retention without using the bulky type, but the thin and light knitted fabric of the present invention as long as the blend ratio of the bulky type in the acrylic fiber C is within 40% by weight with respect to the blended yarn. It is preferable that the heat retention is rather improved without greatly deteriorating the characteristics of the ground. The bulky type refers to a fiber that shrinks in the longitudinal direction of the yarn under wet heat and heat-sensitive heat treatment and spreads in the radial direction.

  The preferable range of the bulkiness of the bulky acrylic fiber is 18 to 40%, and more preferably 18 to 25%. Here, the bulkiness is obtained by calculating the shrinkage rate of the yarn before and after the treatment by wet-heat treatment after collecting a certain length of fiber. If fibers having a bulkiness of more than 40% are used, the thickness of the fabric increases and a thin and light fabric cannot be obtained. Moreover, the blending ratio of the bulky fiber contained in the acrylic fiber C is 10 to 40% by weight, more preferably 10 to 30% by weight with respect to the blended yarn. When the mixing ratio exceeds 40% by weight, the knitted fabric is thick, the fabric weight is heavy, and it is difficult to make a thin and light fabric.

  The mixing ratio of the acrylic fiber B in the blended yarn of the present invention is 20 to 75% by weight, and preferably 30 to 60% by weight. When the mixing ratio is less than the above range, the inter-fiber gap with the acrylic fiber C is lowered, and the heat retention is lowered. On the other hand, if the above range is exceeded, the inter-fiber gap is lowered, the heat retaining property is lowered, and the dyeability is also deteriorated. Further, the mixing ratio of the acrylic fibers C in the blended yarn is 10 to 40% by weight, and preferably 15 to 30% by weight. When the mixing ratio is less than the above range, the inter-fiber gap with the acrylic fiber B is lowered, and the heat retention is lowered. On the other hand, if the above range is exceeded, the inter-fiber gap is lowered, the heat retaining property is lowered, and the texture becomes hard.

  The weight ratio of the acrylic fiber B to the total of the hygroscopic fiber A and the acrylic fiber C in the blended yarn of the present invention is 2: 8 to 8: 2, preferably 3: 7 to 8: 2. Even if the weight ratio of the acrylic fiber B is less than 20% or higher than 80%, the inter-fiber void is lowered and the heat retaining property is not improved. Further, when the weight ratio of the acrylic fiber B is less than 20%, it is difficult to produce fine count yarns.

  The thickness of the blended yarn of the present invention is 55 to 100, preferably 70 or more, and more preferably 80 or more. If it is thicker than the above range, it is difficult to obtain a thin, light and warm knitted fabric. Moreover, when it is thinner than the count of the said range, a knitted fabric will become thin too much and heat retention will fall. The twist coefficient (K) of the blended yarn of the present invention is preferably 2.8 to 4.5, more preferably 3.0 to 4.1. When the twisting coefficient is less than the above range, the inter-fiber void ratio is increased, but the yarn strength is lowered, and the spinning property and the knitting property are deteriorated, making the production difficult. When the twisting coefficient exceeds the above range, the spinning property and the knitting property are improved, but the inter-fiber void ratio is low, and it is difficult to obtain the target heat retention.

  When viewed in cross section, the blended yarn of the present invention has a porosity between fibers of 30 to 60%, more preferably 30 to 40%. The porosity is a ratio of fibers and spaces constituting the yarn cross section. If the porosity is less than the above range, the target heat retention rate cannot be obtained, and if it exceeds the above range of 60%, heat retention can be obtained, but the yarn strength is reduced or consumption such as pilling when the garment is made. Performance decreases.

  The blend ratio of the blended yarn in the knitted fabric of the present invention is 40 to 100% by weight, preferably 50 to 100% by weight, and more preferably 75 to 100% by weight. The higher the blend ratio of the blended yarn in the knitted fabric, the better. On the other hand, when the mixing ratio is less than 40% by weight, it becomes difficult to provide a thin, light and warm performance to the knitted fabric.

  The moisture content of the knitted fabric of the present invention is 3 to 25%, preferably 3 to 15%. Therefore, when the knitted fabric of the present invention is used, comfort can be maintained without stuffiness when moving from the cold outdoors to the room. When the moisture content is smaller than the above range, the knitted fabric has no moisture absorption performance, and the feeling of stuffiness during wearing is not reduced. Moreover, in order to make it higher than the said range, it is necessary to make the mixing rate of a hygroscopic fiber more than the range of this invention, the porosity between fibers falls, and it is hard to become a light, thin and warm knitted fabric.

The knitted fabric of the present invention is characterized by high heat retention and moisture absorption while pursuing thinness and lightness. Therefore, the thickness of the knitted fabric of the present invention is 0.5 to 1.2 mm, preferably 0.5 to 1.1 mm, and the basis weight is preferably 120 to 160 g / m ² . If the thickness and basis weight are less than the above ranges, it is difficult to obtain warmth, and if it exceeds the above ranges, it will exceed the thin and light category intended by the present invention.

  The knitted fabric of the present invention is not particularly limited in the knitted structure, but should be considered so that the thickness is reduced. For example, the knitted fabric of the present invention may be a circular knit single knit, double knit, or warp knitting. As a structure suitable for a structure in which the thickness of the knitted fabric is not easily increased, there are a milling cutter, a single bag, a tengu, a Milan rib, a reversible, a bear tengu, a bear milling, and the like. In order to obtain a thin and light material, it is preferable to set these knitting structures to an appropriate density. The appropriate density varies depending on the knitting structure, but may be set as appropriate within the range of 20 to 50 / inch wales and 30 to 100 / courses. The specific volume of the knitted fabric of the present invention thus produced is 3 to 10 cc / g, and the more preferable specific volume of the knitted fabric is 3.5 to 6.5 cc / g. The numerical value of this specific volume is not so high as a knitted fabric having heat retention. The reason for this is presumed to be due to the fact that the knitted fabric is thin and light, but it is thought that the warm blended yarn with fine voids achieves higher heat retention than the apparent specific volume. . Although the heat retention rate of the knitted fabric of the present invention is high, it is actually 15 to 35%. When the heat retention rate is lower than 15%, it becomes difficult to feel the warmth when worn, and when it is higher than 35%, it is difficult to reduce the thickness and weight.

  The knitted fabric of the present invention has a friction withstand voltage of 0 to 3000 V and a half-life of 0 to 30 seconds, and more preferably has a friction withstand voltage of 0 to 2800 V and a half-life of 0 to 25 seconds. When the friction withstand voltage and the half-life are above the above ranges, static electricity is generated at the time of wearing, and wearing comfort cannot be obtained.

  In the knitted fabric of the present invention, other yarns can be knitted in a range where the blend ratio of the blended yarn does not fall below 40% by weight. However, in this case, it is preferable that the yarn used for maintaining the thin and light characteristics is a thin yarn of 60 or more. Although it will not specifically limit if it is 60th or more fine thread | yarn, For example, a filament of 50 dtex or less, a blended yarn, or a composite yarn is used suitably. As other yarns to be knitted, there are specifically nylon or polyester filaments or false twisted yarns, and short elastic fibers or covered elastic yarns composed of long fibers and elastic fibers. As the coated elastic yarn, FTY (filament twisted yarn) in which a filament and an elastic yarn are twisted, a single (double) covering yarn, an air covered yarn, a false twist composite yarn that is mixed simultaneously with false twist processing, and the like are used. . Core composite yarns, pliers, etc. are used as composite yarns of short fibers and elastic yarns. As the elastic yarn, polyurethane-based spandex, polyolefin-based elastic yarn, polyester-based elastic yarn, polyester-based latent crimped yarn, or the like can be used. The fineness of the elastic yarn is preferably 22 dtex or less. When the fineness exceeds 22 dtex, the fineness of the mixed yarn becomes large, or the balance with the inelastic yarn to be mixed becomes worse. The elastic yarn draft rate at the time of blending is preferably set to a low magnification of 1.5 to 2.5 times. More preferably, it is about 1.8 to 2.2. When the elastic yarn draft ratio exceeds 2.5 times, the expansion / contraction power is too strong, the shrinkage of the knitted fabric increases, and it becomes difficult to obtain a thin and light knitted fabric.

  For the dyeing process of the knitted fabric of the present invention, a normal acryl fiber or a mixed knitted fabric processing method with other fibers may be adopted, but care should be taken not to crush the inter-fiber void structure of the blended yarn of the present invention. It is necessary to process it. For example, it is required not to process the knitted fabric with tension or compression in the thickness direction more than necessary during drying or heat treatment. In addition, when the liquid temperature is lowered after scouring or dyeing, the acrylic fiber will dull if it is done rapidly, so the temperature should be lowered slowly.

  It is preferable to apply a general finishing agent such as a softening agent or an antistatic agent to the knitted fabric of the present invention, and other various functional processings may be applied alone or in combination. Examples of functional processing include, but are not limited to, antifouling processing such as hydrophilic processing, UV cut processing, antistatic processing, and skin care processing.

  Next, the present invention will be specifically described using examples and comparative examples, but the present invention is not limited to these examples. All modifications in the embodiments without departing from the spirit of the invention are included in the technical scope of the present invention. The measurement method used in the present invention is as follows.

<Porosity between fibers>
The blended yarn was gently taken out from the knitted fabric and fixed to the SEM sample stage with adhesive tape. With the sample stand frozen with liquid nitrogen, cut the cross section perpendicularly to the fiber axis direction with a razor to cut the cross section, and take a photo of the cross section of the fiber with a scanning electron microscope (SEM) S3500N manufactured by Hitachi, Ltd. It was. From this cross-sectional photograph, the ratio of the total area occupied by the blended yarn to the area of the space excluding the area actually occupied by the single yarn was measured.
Yarn porosity of blended yarn (%) =
(Total area occupied by blended yarn-Actual area occupied by single yarn)
/ (Total area occupied by blended yarn) * 100
The area actually occupied by the single yarn was the sum of the cross-sectional areas of the single yarns in the cross-sectional photograph.

A method for deriving these areas from image analysis using computer software is described below.
A cross-sectional photograph is taken in as image data, and Adobe PhotoShop ver. Using 6.0, the range of the total area occupied by the blended yarn and the cross-sectional area of each single yarn were specified, and binarization processing was further performed to obtain an image for analysis. At this time, the total area occupied by the blended yarn was set to a range in which all the outer sides of the cross-sectional contours of the fibers located in the outermost layer were connected. An image for analysis created by these operations is further converted into image analysis software, Lia32 ver. Using 0.376β1, the total area occupied by the blended yarn and the total area of the cross-sectional areas of each single yarn were calculated, and the porosity of the blended yarn was obtained using these values. As these calculation means, image processing software and image analysis software other than those described above may be used. Further, a range that requires measurement may be cut out from an actual photograph and calculated from the weight ratio.

<Measurement of bulkiness>

<Moisture content of fiber and knitted fabric>
The fiber or knitted fabric is treated in a drying box at 105 ° C. for 3 hours to make it completely dry, and the weight W ₀ is measured using a weighing bottle. Thereafter, the fiber and the knitted fabric are allowed to stand in an atmosphere of 20 ° C. and 65% RH for 24 hours, and the weight W ₁ after the standing is measured. The obtained value was substituted into the following equation to determine the moisture content. The measured value was an average value of n = 3.

<Heat retention rate>
Using a thermolab II manufactured by Kato Tech, set the BT-BOX BT plate (hot plate) to 35 ° C, assuming a human skin temperature, in an environment of 20 ° C and 65% RH. And measure the power consumption W when the amount of heat transfer is balanced. Further, the power consumption amount W0 under the condition where no sample is placed is measured. The heat retention rate is calculated by the following formula.
Thermal insulation rate (%) = {(W0−W) / W0} × 100
The BT plate is 10 cm × 10 cm in size, but the sample is 20 cm × 20 cm. Usually, the sample is contacted with a hot plate, and the heat retention rate of the present invention is measured by providing a spacer such as a fired polystyrene having a heat insulating property on the hot plate and providing a gap of 5 mm from the sample.
In addition, as an index of “warmth”, in the measurement result of the heat retention rate, less than 15% was determined as x, and 15% or more was determined as ◯.

<Thickness of knitted fabric>
It measured by (5) thickness of JIS-L-1018 6.5 knitted fabric test method.

<Specific volume of knitted fabric>
The specific volume was calculated by the following formula using the measured values of the thickness of the knitted fabric and the basis weight.
Specific volume (cc / g) = {knitted fabric thickness (mm) / knitted fabric basis weight (g / m ² )} × 1000

<Mixing ratio measurement>
The mixing rate of the hygroscopic fiber A and the highly hygroscopic fiber in the blended yarn was measured according to the mixed rate test method of JIS-L1030-1 (2005) and JIS-L1030-2 fiber products. The mixing ratio of the acrylic fiber B and the acrylic fiber C is measured by placing the remaining acrylic fiber on a black velvet plate and enlarging it with an optical microscope. Acrylic fiber C is selected and the number of each fiber is measured. The total fineness was obtained by multiplying the number of constituents of each fiber and the single yarn fineness, and the mixing ratio was obtained from the ratio of the total fineness of each fiber. The measured value was an average value of n = 20. In addition, the fineness of various fibers, such as acrylic, measured the diameter of the cross section of the thread | yarn by the metal section method, and calculated | required the fineness of each fiber from the fiber diameter.

<Friction withstand voltage>
It measured according to JIS-L1094 friction withstand voltage. The measurement environment was 20 ° C. and 40% RH, the friction cloth was a cotton cloth, and the measurement was carried out using the value in the higher direction among the average values of the five sheets in each direction for the five wale / course directions.

<Half life>
It measured according to JIS-L1094 half life. The measurement environment was 20 ° C. and 40% RH, and the measurement value was an average value of n = 5.

<Moisture sensation test>
A long-sleeved inner shirt (M size) with a round neck was created from the knitted fabric, and a wearing test was conducted on five male adult males aged 20 to 50 years. The subjects had their shirts, work clothes and winter clothes on top of the inner shirts. First, assuming an outdoor environment in winter, the environmental test room is set to 5 ° C. and 30% RH, and the rider gets on a Welby Electric Walker WB-209 for 15 minutes at a slow speed of 3.5 km / hour. I had you walk. After that, just take off the warm clothes and immediately have the same type of electric walker in a constant temperature room at 20 ° C 65% walk for another 5 minutes and walk at a speed of 2.5 km / hour. A questionnaire survey was conducted on the feeling of stuffiness immediately after wearing. If all 5 people answered that there was no stuffiness, ◎, if 3-4 people answered that there was no stuffiness, ○, if there were 2 or less people who did not feel stuffiness, △. If it is 1 or less, it will be marked as x.

<Comprehensive evaluation>
In the judgment results of the indicators of “warmth”, “lightness” and “thinness”, ○ is 5 points, △ is 3 points, × is 0 points, and the judgment result of the “steaming wearing test” is ◎. The score was determined with 5 points, 3 points, 3 points, 1 point, and 0 points. Furthermore, in comprehensive evaluation, the score of each item was totaled, and 0 points to 10 points were evaluated as x, 11 points to 15 points as Δ, and 16 points to 20 points as 点.

<Example 1>
30% by weight of rayon staple as hygroscopic fiber A (“Corona” manufactured by Daiwabo Rayon, BH, 0.9 dtex, fiber length 38 mm, measurement environment 20 ° C., moisture content 12% under 65% RH environment) 30% by weight, acrylic fiber B Cationic dyeable acrylic short fibers (UF type manufactured by Nippon Exlan Industries, 0.5 dtex, fiber length 32 mm) 50% by weight, antistatic / anti-pill type cationic dyeable acrylic fibers (acrylic fiber C manufactured by Nippon Exlan Industries, 822) (Type, 1.0 dtex, fiber length 38 mm) 20% by weight was blended using an OHARA blender and then turned into a card sliver using a card machine manufactured by Ishikawa Seisakusho.
