Description

  The present invention relates to a cloth for clothing that is comfortable to wear when sweating in sports and the like, and an improvement in sports clothing and underwear.

  Japan's summer is hot and humid and sultry, and when sweating, clothes such as sports clothes and underwear get wet and the comfort becomes worse. Conventionally, cellulose-based fibers such as cotton have been used in sports clothing and underwear. However, cellulose-based fibers are difficult to dry when absorbed by sweating, have a sticky feeling, and are not necessarily comfortable to wear. In order to improve this, there are also sports clothing and underwear that use polyester fiber, which is a representative of hydrophobic fibers, but because it does not absorb sweat at all, even if it sweats, the action of moving sweat to the outside of the clothing is poor, Sweat remains on the skin and is not sticky or comfortable. There are also polyester and cotton blends, but as long as cotton is used, the point of difficulty in drying is not improved. There are also garments that use nylon fibers, but nylon is essentially hydrophilic, and when the fibers absorb water due to sweating, they are not very sticky and comfortable to wear.

In order to solve the above-mentioned problems, the present inventor proposed a garment having a refreshing feeling using a twisted yarn obtained by twisting ethylene vinyl alcohol fiber and cotton spun yarn in Patent Document 1 below.
JP 2001-295158 A

  However, the problem of stickiness when sweating is still insufficient in the conventional garments, and the wearer is required to further improve the comfort.

  In order to solve the above-described conventional problems, the present invention provides a clothing fabric, sports clothing, and underwear that sweat easily perspires to move to the outside of the clothing, is easy to dry, is less sticky, and has a refreshing feeling. The purpose is to provide.

  The cloth for clothing of the present invention is a cloth for clothing comprising a knitted fabric or a woven fabric formed on the front surface and the back surface, wherein the front surface is mainly formed by hydrophobic fiber yarns, and the back surface is mainly formed by hydrophilic synthetic fiber fibers. The polyester fiber yarn formed on the back surface of the polyester fiber yarn is characterized in that a hydrophilic resin is fixed to the fiber surface.

The fabric is composed of weft knitting, warp knitting, or woven fabric. Any knitted fabric or woven fabric may be used. Furthermore, in order to easily move moisture such as sweat to the surface and make it difficult for moisture to remain on the skin surface, a two-layer structure of front and back is preferable. A two-layer structure can be obtained by, for example, a method in which two yarns of different types are aligned and supplied to a knitting machine so that one of the yarns always appears on one side, or a method using a jacquard structure. It is done. As another configuration, for example, a structure in which a part of the yarn used on the back surface appears on the front surface, such as a half tricot knitting, is also possible.

  As for the knitting structure, weft knitting includes tengu knitting (flat knitting), Kanoko, splicing knitting, pile knitting, rubber knitting (rib knitting), pearl knitting (garter knitting), single knitting knitting, double knitting knitting, double knitting knitting, etc. Tricot, half tricot, and Raschel knitting can be used for warp knitting. In the case of a woven fabric, general structures such as plain weave, twill weave, and satin weave can be used.

  The yarn used on the surface is mainly a hydrophobic fiber such as polyester fiber yarn, cotton / polyester fiber blended yarn, or even if a part of the yarn constituting the back surface appears on the surface as described above. Good. When many hydrophobic fibers are present on the surface, moisture is efficiently diffused and drying properties are also good.

  The back surface is mainly formed of hydrophilic synthetic fiber yarns and polyester fiber yarns, and the preferred presence ratio is in the range of 25 to 75% by mass of hydrophilic synthetic fiber yarns and in the range of 25 to 75% by mass of polyester fiber yarns. .

Yarns are supplied in the order of a, b, and c, and then knitted back to a. Ethylene vinyl alcohol fibers are exposed at a rate of 67% on the back side.

  By comprising in this way, since the fiber side (for example, ethylene vinyl alcohol fiber) with the hydrophilic molecular structure of the fiber is arrange | positioned at the skin side, a refreshing feeling can be exhibited. In addition, the polyester fiber yarns on the front and back surfaces have a hydrophilic resin fixed to the fiber surface, so that when sweating, sweat easily moves to the outside of the clothing and is easy to dry, reducing stickiness. .

  Hereinafter, the present invention will be described more specifically with reference to examples.

First, a method for measuring the amount of heat transferred at the time of contact of the fabric and the wet friction force in the following examples will be described.
(1) Heat transfer during contact As a test condition, Thermolab II (manufactured by Kato Tech Co., Ltd.) was used to verify the thermal conductivity effect of the fabric when the temperature was 20 ° C. and the relative humidity was 65% RH. , Length: 10 cm, width: 10 cm, height: 10 cm A sample piece of 10 cm × 10 cm is placed on a block made of polystyrene foam having high heat insulation properties, and further above it is 40 ° C. with a heat source plate of length: 10 cm, width: 10 cm. Place a heated heat source on At this time, the amount of heat transferred from the heat source to the sample piece was measured as the amount of heat transferred during contact. The higher the value of the amount of heat transferred at the time of contact, the higher the thermal conductivity, and heat can be dissipated by quickly conducting the heat inside the garment to the outside of the garment. It can be said that it is excellent in the cool feeling of contact.
(2) Wet friction force In order to measure the wet friction force, a sample piece is brought into contact with a metal roller having a diameter of 5 cm, and the resistance force when the roller is rotated is measured in a wet state. At this time, in a test environment where the temperature is 20 ° C. and the relative humidity is 65% RH, the size of the sample piece is 5 cm in length, 20 cm in width, 0.5 ml in water supply, and the rotation speed of the roller is 4 cm / min. The load was set to 30 gf and the frictional resistance was measured. The lower the value of the wet friction force, the lower the frictional resistance with the skin even in the state of moisture absorption by sweating, etc., so that the feeling of stickiness is less and the smooth comfort can be maintained.

(2) Ammonium persulfate: 0.1% by weight
(3) Water: 88.9% by weight
Next, after squeezing with mangle (squeezing rate 100%), it was treated with high-pressure steam at 120 ° C. for 30 minutes, then washed with water and dried.

  Thus, the amount of heat transferred and wet friction force at the time of contact between the knitted fabric to which the hydrophilic resin was added and the untreated knitted fabric were measured. The results are shown in FIGS. As apparent from FIGS. 5 to 6, in the knitted fabric to which the hydrophilic resin is added, the back surface (skin side) has a polyester fiber and an ethylene vinyl alcohol fiber (the “Sophista”) in a mass ratio of 25/75 to 75/25. When the range was in contact, a cooling sensation was obtained and the degree of stickiness was low.

(Example 2, Comparative Examples 1-4)
In Example 1, the same knitted fabric as in Example 1 was used except that the back surface (skin side) was polyester fiber: ethylene vinyl alcohol fiber = 35/65 (mass ratio) by weight ratio of polyester fiber and ethylene vinyl alcohol fiber. It was.

  Comparative Example 1 was a knitted fabric that was the same as that of Example 2 and was not subjected to immersion treatment with a chemical solution for hydrophilic treatment.

  In Comparative Example 3, a knitted fabric with 100% by mass of polyester fibers on both the front and back surfaces was used.

  Comparative Example 4 was a knitted fabric that was 100% by mass on the front surface: polyester fiber and 100% by mass on the back surface: ethylene vinyl alcohol fiber (“Sophista”) and was not subjected to a dipping treatment with a chemical solution for hydrophilic treatment.

  The amount of heat transferred during contact was as shown in Table 1 below.

  The wet friction force was as shown in Table 2 below.

Next, shirts were created from the fabrics of Example 2 and Comparative Examples 1 to 3, and the following questionnaires were conducted on “cool feeling” and “stickiness” to 10 subjects.
(1) Questionnaire on feeling of cold Assuming exercise during the summer, sweating conditions: 30 ° C, relative humidity 70% RH, and after 30 minutes of light running at 6km / h on a treadmill It was. There are 10 testers, 5 feelings of coolness immediately after wearing, “5: quite”, “4: somewhat”, “3: normal”, “2: not”, “1: not at all”. Rated by stage. The results are shown in Table 3 below.

(2) Questionnaire about stickiness In the above-mentioned wearing test, stickiness when sweating due to running is as follows: “1: Pretty”, “2: Somewhat”, “3: Normal”, “4: Somewhat”, “5: Absolutely” It was evaluated on a five-point scale. Sweating conditions: A questionnaire after 30 minutes of light running at 6 km / h on a treadmill in an environment of 30 ° C. and 70% relative humidity was taken. The results are shown in Table 4 below.

  As is apparent from Tables 3 to 4, Example 2 is superior to both the feeling of cooling and stickiness compared to other materials, although the feeling of stickiness during sweating is slightly less than that of polyester (Comparative Example 3). The result which shows sex was obtained.
