Improved structure of thermal insulation textile

Abstract

The invention discloses an improved structure of a thermal insulation textile. The surface layer of the textile is a cotton weaving layer; the inner layer of the textile is a galling-trimmed super-fine denier terylene stretch yarn layer (fibers, the fiber number of which is below 0.55dtex, are super-fine denier yarns in industry, wherein dtex is decitex and refers to the gram of a fiber bundle which is 10000 meters long); the middle layer of the textile is a yarn layer with elastic traction; the fabric structures of the surface layer and the inner layer of the textile are plain knitting structures; the surface layer and the inner layer of the textile are weaved together through the middle layer of the textile; the surfaces of the surface layer and the inner layer of the textile are provided with a plurality of convex longitudinal strips at intervals under the elastic traction action of the terylene cladding yarns of the middle layer of the textile, thereby forming a thicker air layer; and moreover, the open air layer of the inner layer is formed after the galling trimming is carried out on the super-fine denier terylene stretch yarn of the inner layer of the textile, thereby greatly improving the thermal insulation rate.

Description

technical field [0001] The invention relates to a fabric, especially a warm-keeping fabric. Background technique [0002] Air layer liner three-layer fabric is one of the main fabrics of knitted thermal underwear at present, and it is woven by double-sided circular weft knitting machine. Its warm-keeping mechanism is to use the elastic recovery of the polyester elastic yarn in the middle layer of the pad to form an air layer, and use the principle of poor thermal conductivity of the air layer to achieve a warm-keeping effect. The disadvantage is that the polyester elastic yarn in the middle pad is easy to be drawn out or exposed from the air layer, which is easy to cause pilling and affect the appearance and wearing. Moreover, the air layer formed by it is thin, and the warmth retention rate cannot adapt to more severe weather. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides an improved structure of a wa...
