Fabric used for making warm underclothes

Abstract

A fabric for heat-insulating underwear is composed of the surface structure made of polyester fibers and substrate made of polyurethane cored cotton yarn. Its productive method includes such steps as weaving by dual-surface loom, pre-treating, and dyeing, finishing, post-treating, scotching, pre-fixating shape, napping, combining, shearing, ironing, swinging, and fixating shape.

Description

technical field [0001] The invention relates to a thermal underwear fabric and a processing method of the fabric, belonging to the technical field of textiles.

AI Technical Summary

Problems solved by technology

[0002] Sprayed cotton wadding, non-adhesive wadding, thermal insulation wadding obtained by spunlace, hollow fiber materials, space cotton and other materials were once used as fabrics for processing thermal underwear, but with the weakness of the above raw materials For example, the understanding of bloated appearance, poor air permeability, lack of moisture drainage, and easy degumming of the composite layer after washing, etc. Therefore, thermal underwear fabrics processed from the above raw materials are gradually withdrawn from the market because they are not valued.

[0003] The real silk thermal cloth involved in CN2438574Y is composed of the fabric lining material of the inner layer and the real silk cotton non-woven fabric of the outer layer, and the outer layer can be provided with a gauze layer. The swimming between them is large, and the washing resistance is extremely fragile, especially if it is not a knitted thermal underwear fabric in the true sense.

[0004] CN1718124A has just released the thermal underwear fabric that is made through a series of processing steps with silkworm cocoon, it is undeniable that this fabric has the advantages of good thermal performance, light and thin comfort, moisture absorption and air permeability ideal, but can't realize industrialized production, to this According to the introduction, the two ends of the common cocoon can be cut off, the middle is cut open, the contents of the cocoon are removed, the cocoon is flattened into small cocoon pieces, the scattered small cocoon pieces are connected by machine or by hand, and the flat fabric cloth is dry-pressed by gravity at room temperature The processing steps are confirmed

[0005] Perhaps due to the above-mentioned reasons, there are mainly two types of underwear fabrics that are relatively common in the market and are well-known to consumers and occupy a dominant position in the market: one is ordinary short plush, ultra-fine and ultra-soft short plush underwear fabrics, this kind The raw material of underwear fabric is all polyester. Although it has softness and warmth retention, its hygroscopicity and air permeability are not ideal. As we all know, polyester fiber is a hydrophobic fiber, which has the commonality of general chemical fibers, so the electrostatic phenomenon is more serious; The degree, brightness and elasticity are not ideal; the hand feeling is poor and the bulkiness is lacking

The second is that all-cotton knitted jersey (that is, all-cotton knitted fabric) is used as underwear fabric, which has many advantages such as certain elasticity, no static electricity, and excellent air permeability, but it has insufficient hand feeling, high shrinkage rate, and poor shape retention effect. , the lines are not round, and the fluff is not plump and even.

[0006] Looking at the advantages and disadvantages of the above two underwear fabrics, the applicant believes that if the respective advantages and disadvantages of these two underwear fabrics can be complemented, it is an ideal move, but so far no similar literature reports and actual Fabric products are on the market
