Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a knitted fabric that has good water absorption and heat retention properties, and more specifically to a knitted fabric that has heat retention properties and properties that prevent the skin from getting wet with sweat when sweating. be.

Conventionally, knitted fabrics with a double weave of a flat weave or nuchal structure using cotton yarn, three-synthetic fiber yarn, or a blend of these yarns have been used to make underwear,
It is used for clothing such as shirts and sportswear, but due to its lack of water absorption, sweat accumulates as water droplets on the skin surface and flows down, further increasing the humidity inside the clothing and causing discomfort. there were. Also, even those with good water absorption properties that use cotton thread on the back side do not release absorbed water sufficiently.

Although it may be comfortable when the amount of perspiration is low, when the amount of perspiration is low, the clothing turns into a water layer that feels wet and adheres to the skin, making it extremely uncomfortable. Particularly when such knitted fabrics are used as sportswear, they hinder muscle exercise, and when the temperature is cold, the adsorbed water gets cold, which tends to cause colds and muscle disorders. To solve this problem, a knitted fabric using cotton yarn on the front side and synthetic fiber yarn on the back side of a double structure has been proposed. However, it was not satisfactory in terms of heat retention.Furthermore, knitted fabrics with raised hair on the front or back side of the knitted fabric are known to improve heat retention. Generally, water absorption is not considered, and even if the material is water absorbent, the back side is water absorbent, so the back side gets very wet, and the feeling of wetness cannot be avoided.

The present invention is intended to eliminate such conventional drawbacks, and its purpose is to quickly transfer sweat and moisture absorbed on the back side of clothing to the front surface.
An object of the present invention is to provide a unevenly distributed water-absorbing knitted fabric having excellent heat retention properties.

Zunawaji 3 The present invention is a knitted fabric in which one side is composed of hydrophobic fiber yarns with a single yarn fineness of 2 denier or less, and the other side is composed of yarns in which hydrophilic fibers account for 50% or more. There it is,
The gist is a unevenly distributed water-absorbing knitted fabric formed by raising at least one surface of the knitted fabric.

The present invention will be explained in detail below.

In the present invention, the stitches on two sides are knitted with yarns of hydrophobic fibers with a single yarn fineness of 2 deniers or less, and the stitches on the other side are knitted with yarns in which hydrophilic fibers account for 50% or more. , stitches made of threads of hydrophobic fibers are arranged on the back side, and stitches made of threads containing hydrophilic fibers are arranged on the front side. When such a knitted fabric is sewn into clothing, the back side is placed on the inside and the front side is placed on the outside. In the present invention, it is important to form the stitches on the back side using hydrophobic fiber yarns composed of thin single yarns with a single yarn fineness of 2 deniers or less. By forming the stitches on the back side with hydrophobic fiber yarns composed of thin single yarns, it exhibits a high capillary effect and can absorb moisture such as sweat at a high speed. In addition, since a single yarn with a fine fineness is used as the knitting yarn for the back stitches, the texture is soft. When the single yarn fineness exceeds 2 deniers, the water absorption rate decreases and the texture becomes hard, which is not preferable.

Next, the stitches on the two surfaces are formed using yarns that account for 50% or more of hydrophilic fibers. Since the front stitches are made of yarn containing hydrophilic fibers, the stitches on the first side are highly hydrophilic and water-containing, and most of the sweat on the body surface that is absorbed by the stitches on the back side is not absorbed. At the same time, it migrates to the stitches on this surface and separates from the skin surface. Therefore, it is possible to prevent sweat from flowing on the skin surface, adhesion of clothing to the body, and excessive increase in clothing humidity. 41 in Table 1n1 above
The 11th stitch must be formed from a yarn containing 50% or more of hydrophilic fiber IF, and if it is less than 50%, sweat absorbed in the back stitches will be quickly and sufficiently transferred to the front stitches. It is difficult to do so.

Furthermore, in the present invention, the knitted surface is raised. Since the knitted surface is brushed, air is retained between each wool, so-called dead air is retained to prevent body heat from dissipating, increasing the heat retention effect. The surface to be brushed may be the front or back surface, or both the front surface or the back surface.6 Depending on the texture of the knitted fabric, care must be taken as raising both surfaces may result in a significant decrease in strength.

When applying the raising process to the knitted surface, any known raising machine such as a needle cloth raising machine or an emery raising machine may be used.
In short, it is sufficient if the knitted surface can be fluffed.

In the case of ordinary fleece knitted fabrics with raised fleece on the back side, when you sweat a lot, each fleece absorbs sweat and has good thermal conductivity, making it easier to dissipate body heat. Also, as sweat accumulates between the hairs, the amount of ted air decreases, resulting in a greater drop in heat retention. However, in the knitted fabric of the present invention, the sweat absorbed on the back side quickly moves to the front side, so there is less sediment remaining in the fleece layer on the back side, and the increase in thermal conductivity due to the sediment is also less and therefore.

There is almost no further decrease in dead air, and the heat retention effect can be maintained as before sweating.

Furthermore, in the case of fleece, when worn as clothing, there is less irritation to the skin 1i and it provides a refreshing comfort. In addition, when the second surface is brushed, the sweat that has been absorbed by the back surface and transferred to the first surface is transferred to the fluff light, and the radiator action increases dispersion and evaporation, making it possible to dry faster. Allows sweat to move to the surface faster.

It has a heat-retaining effect, with less loss of body heat due to sweat, and can be refreshingly comfortable to wear. In addition, since drying is carried out using fluff light, there is almost no noise due to the heat of evaporation, and it has an excellent heat retention effect.

Furthermore, when both the first and back sides are brushed, both of the above effects are combined, and the heat retention effect is extremely high.

The performance of the knitted fabric of the present invention is maintained even after long-term continuous use due to the hydrophilic nature of the two surfaces, the transfer of moisture absorbed on the back surface to the surface, and the evaporation of moisture from the surface.

In the present invention, hydrophilic fibers include cellulose fibers such as cotton and rayon, and synthetic fibers subjected to hydrophilic processing. Hydrophobic fibers include fibers with hydrophobic surfaces such as polyester fibers, acrylic fibers, and wool.

In the present invention, the effects of the present invention can be further improved by applying hydrophilic finishing to the two surfaces and hydrophobic finishing to the back side.

In the present invention, since the above configuration is adopted,
When used as clothing, sweat and moisture absorbed on the back side can be quickly transferred to the front side.

It has excellent heat retention properties.

The present invention will be specifically explained below with reference to nine examples.

Example 1 Cotton combed yarn count 30 was used as the front yarn, polyester false twisted yarn 150d/144f was used as the back yarn, and polyester false twisted yarn 7 was used as the joining yarn! A tack reversible knitted fabric was knitted using a 20 gauge knitting machine using M/36f. Then,
This is then brushed on the back side using a needle cloth napping machine to create a fleece knitted fabric, which is then refined using a conventional method.

A knitted fabric was obtained by dyeing and heatseno I. 1 - Sewing training wear using the obtained knitted fabric.

When I put it on, it was very warm with the fleece lining. Furthermore, even though I exercised and sweated a lot, my insides felt dry and refreshed with almost no wetness. Also,
Even after exercise, it did not feel wet or cold, and had high heat retention properties.
