Problems solved by technology

However, since the raw material is wool, there are the following problems: difficulty in handling such as easy adhesion of insects and damage; high price; etc.
This pile woven fabric has a sense of tension because it is a woven fabric, but it has almost no stretchability. Regarding the stretchability, it can be solved by using spandex, but since the spandex fiber It is easy to deteriorate, so there is a problem of poor durability
[0005] Based on the above, the actual situation is that there is no proposed pile circular knit of synthetic fibers that have moderate tension and stretchability, and are also excellent in physical properties such as pilling resistance and washing dimensional change, and can replace wool melton fabrics. thing

Embodiment 1

[0121] exist image 3 In the structure shown, polyester raw yarn with a boiling water shrinkage rate of 12.5% ​​of 84 dtex 12 filaments was used as the yarns A (1) and A (2) forming the inside of the double ring, and 110 decitex 96 filaments were used in boiling water. A polyester false-twisted processed yarn with a shrinkage rate of 6.0% was used as the yarns B(1) and B(2) forming the outer sides of the double ring, and two polyester raw yarns with a boiling water shrinkage rate of 12.5% ​​of 84 decitex 12 filaments were used in combination. As the yarns C(1) and C(2) forming the side opposite to the double loop, a knitted fabric was knitted by a 22G double-knit circular knitting machine.

[0122] According to the usual dyeing process of polyester knitted fabrics, the gray cloth is relaxed, refined and dyed, and then the surface with double rings is subjected to a napping process, a water repellent is applied, and finishing and setting processing are performed to obtain the s...

Abstract

Raised circular knitted fabric, which is a circular knitted fabric with double loops formed by overlapping at least two or more synthetic fiber multifilaments, at least one side of the circular knitted fabric has been raised, and the formula (T2 / T1) [T1: Thickness (one sheet) measured by the method prescribed by JIS, T2: Thickness measured by the same method prescribed by JIS with the fabric folded in half] The FT index expressed is 2.1 or more. According to the present invention, it is possible to provide a napped circular knitted fabric having a feeling of tension and stretchability suitable for coats and jackets, and having excellent physical properties such as pilling resistance and dimensional change after washing.

Description

technical field [0001] The present invention relates to a napped circular knitted fabric, and more specifically, to a napped circular knitted fabric having a sense of tension and stretchability suitable for coats and jackets, and having excellent physical properties such as pilling resistance and washing dimensional change . Background technique [0002] In the past, outerwear and jackets for winter were required to be water-repellent, strong, and heat-retaining. Therefore, fabrics obtained by plain-weaving or twill-weaving carded wool yarns and then covering them with fluff were often used. Material (melton fabric). However, since the raw material is wool, there are problems in that it is difficult to handle such as easy adhesion of insects and damage, high price, and the like. [0003] As a substitute therefor, fleece materials using synthetic fibers have been sold in large quantities on the market. As one of them, the following raised double-sided circular knitted fabr...
