High-density knitted fabric, and production method and application thereof

Abstract

The invention discloses a high-density knitted fabric, and a production method and an application thereof. More than 50% by weight of yarns of the high-density knitted fabric are split nylon-dacron composite yarns, the melting point of the nylon component of the nylon-dacron composite yarn ranges from 180 DEG C to 210 DEG C, the bending rigidity of the high-density knitted fabric is measured to be higher than 0.06 gf.cm<2> / cm through a KES method, and the ventilatory capacity of the high-density knitted fabric is measured to be lower than 60 cm<3> / cm<2> / sec through a JISL1096-2010 method. Through routine weight reducing processing of the high-density knitted fabric, a tight, stiff and smooth product can be obtained, and the high-density knitted fabric can be used for making jackets, wind coats or trousers or the like.

Description

technical field [0001] The invention relates to a high-density knitted fabric and its production method and application. Background technique [0002] At present, there are many kinds of microfiber high-density fabrics on the market. From the perspective of fabric form, they include woven and knitted fabrics. Although woven fabrics are good in stiffness, they are not elastic enough and the wearing comfort is affected; while knitted fabrics Although it has good elasticity, it is too soft and lacks firmness. It needs to be improved by adding stiff resin processing during finishing processing, and its durability is not good. [0003] As one of the raw materials of superfine fibers, polyester-nylon composite yarn is very popular. For example, the patent document CN102704140A discloses a fabric for clothing. By using ordinary polyester yarn as the warp yarn and the polyester-nylon composite yarn as the twill weave of the weft yarn to form a fabric, then carry out alkali reductio...

Problems solved by technology

For example, the patent document CN102704140A discloses a fabric for clothing. By using ordinary polyester yarn as the warp yarn and the polyester-nylon composite yarn as the twill weave of the weft yarn to form a fabric, then carry out alkali reduction, sanding, and dyeing to achieve soft hand feeling and water and oil absorption. However, such fabrics are not elastic enough, and the density and stiffness have not been improved, so they are not suitable for making jackets, windbreakers, etc.

In order to improve the elasticity and increase the density of such fabrics, the patent document CN103126625A discloses a method of first using caustic soda and then benzyl alcohol to open the polyester-nylon composite yarn to obtain a superfine fiber high-density wiping cloth (knitted fabric) , the cloth surface of the resulting wiping cloth is tight, so the liquid absorption and retention properties and the dirt storage properties are relatively superior, and the pollution of the cleaning solvent can be avoided at the same time, but the hand feeling is still soft, and the processing method is relatively complicated, especially the use of benzyl alcohol easy to cause pollution to the environment
