Double-layer down quilt fabric

Abstract

The invention discloses a double-layer down quilt fabric. The fabric comprises a fabric body; the fabric body has a double-layer weaving structure and comprises an upper-layer fabric and a lower-layerfabric; the fabric body is woven by adopting a double-layer plain weave structure, and the upper-layer fabric and the lower-layer fabric both adopt fine-denier polypropylene yarn as warp yarn and fine-denier nylon yarn as weft yarn. In a weaving process of the fabric body, an exterior-and-interior layer changing structure is adopted, first interweaving lines in the warp direction are formed by secondary exterior-and-interior layer changing of weft yarn, and second interweaving lines in the weft direction are formed by secondary exterior-and-interior layer changing of warp yarn; the first interweaving lines and the second interweaving lines are mutually staggered to form velvet filling cells arranged in an array. An interruption is positioned at the portion, between the two corresponding adjacent second interleaving lines, of each first interweaving line. According to the double-layer down quilt fabric, the production steps are simplified, the production efficiency is improved, the production cost is reduced, the sealing property is good, a down deviation phenomenon is unlikely to occur, and the down permeation prevention effect is great.

Description

technical field [0001] The invention relates to the textile field, in particular to a double-layer duvet fabric. Background technique [0002] The filling of duvets is mainly down, which grows on the abdomen of geese and ducks, and is called feathers in the shape of reed flowers. Because down is a kind of animal protein fiber, it has higher thermal insulation than cotton (vegetable cellulose), and the down ball-shaped fiber is densely covered with tens of thousands of small triangular pores, which can shrink and expand with temperature changes, resulting in a temperature-regulating function. It absorbs the flowing heat from the human body and isolates the invasion of cold air from the outside. Therefore, duvets are widely used as the most insulated quilts. When producing duvets, the quilt surface is usually divided into individual square cells by needlework. Through the blocking effect of the small grid division, the down can be prevented from being displaced randomly, and ...

Problems solved by technology

[0003] In order to solve the above-mentioned technical problems, the present invention provides a double-layer down quilt fabric, which adopts two layers of outer and inner layers, and forms a down-filled unit cell through the first interweaving thread and the second interweaving thread, which solves the problem of the existing down quilt fabric The anti-drilling performance is poor, the processing steps are cumbersome, the production cycle is long, the manufacturing cost is high, and the use effect is not ideal
