Description

[Detailed description of the invention] This invention is a knitted fabric that is comfortable to wear against sweat, that is, a knitted fabric that transmits insensible sweat or sweat from the human body and does not feel wet even when sweating, especially for sports. This article relates to knitted fabrics that are optimal for clothing.

Conventionally, among the materials for sports clothing, 100% polyester knitted fabrics, mixed knitted fabrics of polyester fibers and cotton, or mixed knitted fabrics with outer polyester and solid line/polyester blend yarns have been used for sweatshirts. Knitted fabrics made of 100% cotton, cotton/polyester blend yarn, or cotton/acrylic blend yarn are often used for fabrics and sports shirts.

In addition, knitted fabrics of 100% nylon and cotton/polyester blend yarns are used for brassieres and the like.

On the other hand, there are various properties required for materials for sports clothing, among which are wash resistance, abrasion strength,
Required properties such as heat retention and elasticity vary depending on the sport, but comfort against sweat and sweat are commonly required values.

Comfort against sweat and sweat is determined by the stuffiness and stickiness of clothing, which are important elements in clothing design, and are greatly influenced by the properties of the fabric that makes up the clothing.

However, at present, the materials used are determined from the viewpoint of comfort against sweating and sweating.
It is determined based on appearance such as texture and color development, and durability such as wear resistance.

The above-mentioned materials for sports clothing that have been conventionally used are no exception. Thick fineness is used.

For this reason, the capillary phenomenon between the fibers could not be exerted significantly, making the garment uncomfortable to wear and, in turn, causing health problems.

In addition, in the case of yarn made of 100% natural fibers or hydrophobic fibers, the former has the effect of absorbing water and moisture, but does not have the function of releasing moisture, and the latter, although it has the effect of releasing moisture. , water absorption, and moisture absorption, and both lacked comfort against sweat as sports materials.

The present invention eliminates these drawbacks by combining hydrophobic fibers with a single yarn denier of 1.0 denier or less and hydrophilic fibers such as cotton or polynosic fibers.
The fabric is knitted with yarns mixed in a ratio of 1:2 and has a weight of 130 to 450 g/d.

The present invention will be explained in detail below.

In order to quickly absorb, permeate, and dissipate sweat, it is necessary to use yarn that is a mixture of hydrophobic fibers with a single yarn denier of 1.0 denier or less and hydrophilic fibers with excellent moisture absorption and water absorption properties. be.

Here, hydrophobic fibers are fibers with an official moisture content (JIS L-1096) of less than 5% at 65% RH and 20°C, and hydrophilic fibers have a difference of 1% or more in official moisture content. refers to what one has.

Examples include polyester fibers, acrylic fibers, polyamide fibers, vinyl chloride fibers, and the like.

Hydrophilic fibers are fibers with an official moisture content (JIS L-1096) of 5% or more at 65% RH and 20°C, such as natural fibers such as cotton, linen, and wool, viscose/rayon, and polynosic fibers. recycled fibers such as

It is necessary that the hydrophobic fiber has a single filament denier of 1.0 denier or less.

The smaller the denier number, the larger the specific volume and the greater the sweat permeation and wicking effect, but it is important to balance the water absorption and wicking performance of hydrophilic fibers and the moisture wicking performance of fine denier hydrophobic fibers. Considering this, it is appropriate that the denier of the hydrophobic fiber is 0.3 to 1.0 denier.

On the other hand, the thinner the hydrophilic fiber is, the more preferable it is, but it is preferably 1.0 to 2.0 denier in single yarn denier, and more preferably 1.01 to 1.5 in single yarn denier.
It is denier.

The mixing ratio of hydrophobic fibers and hydrophilic fibers is preferably in the range of 2:1 to 1:2.

If the mixing ratio of hydrophobic fibers and hydrophilic fibers is less than 2:1, it will be difficult to absorb sweat sufficiently in the case of rapid sweating. If it is 2 or more, the absorbed sweat will be released in a short time,
Since it is difficult to diffuse, it gives rise to a sticky feeling, which is not desirable.

Mixing of hydrophobic fibers and hydrophilic fibers can be done in the case of filament-to-filament, or in the case of filament-to-stable (
In this case, either the hydrophobic fiber or the hydrophilic fiber may be a filament or a stable fiber.

), stable and stable, either is possible, but stable and stable is more preferable because it gives a good feel.

In the case of filaments, for example, the yarns are drawn on a knitting machine, the yarns are mixed in multiple layers, the uniformly mixed yarns, etc. In the case of stable and stable, the yarns are yarns made by blending means, blending means, etc. Further, in the case of stable and filament, yarns are obtained by blending means, multi-layer mixing means, homogeneous mixing means, etc.

The total denier is suitably 40 to 600 deniers, but is not limited to this.

As described above, any means may be used to mix the hydrophobic fibers and hydrophilic fibers that form the silk thread, but in any case, it is necessary that the mixing ratio is 2=1 to 1:2.

Further, the knitted structure of the silk fabric may be any knitted structure, but it is necessary that the date of the entire knitted fabric is 130 to 450 g/rd.

If it is less than 130 g/d, the dough will become too tingly and sticky.

In addition, when it exceeds 450 g/d, the amount of sweat absorption increases,
Sweat is less likely to evaporate, making you feel colder.

The knitted fabric with the above structure reduces the uncomfortable factors associated with sweat, such as wetness, sweatiness, stickiness, and heat sensation, and the use of fine denier yarn as the hydrophobic fiber improves the texture. It is soft and feels good to the touch even when used on a desk, making it ideal for game shirts and sweatshirts.

Example Polyester fiber single yarn denier 0.7 denier and cotton single yarn denier 1.5 denier were blended at 1=1 and 50s/
A blended yarn of No. 1 was formed.

Using this yarn, a 30-inch 26-gauge knitting machine was used to make the first
The tuck brackets shown in the figure were organized.

The fabric weight of the knitted fabric was 170 g/po.

Comparative example Polyester fiber single yarn denier 2.2 denier and cotton single yarn denier 1.9 denier were blended in a ratio of 1=1 to 5ω/1.
A blended yarn was formed.

The yarn was knitted into the same knitting structure as in the example.

The knitted fabrics of Examples and Comparative Examples were evaluated using an in-garment climate simulation device (see Japanese Patent Laid-Open No. 58-21164).

The environmental conditions of the clothing climate simulation device are set to 20°C.
The simulated skin temperature of 965% RH1 was set at 35° C., and it was assumed that one game shirt was worn.

The results for maximum clothing humidity and equilibrium clothing humidity are shown in Table 1.

As can be seen from Table 1, the Examples according to the present invention maintained a comfortable humidity inside the clothes (50±10% RH), but the Comparative Examples were out of this range.
