Down fabric and preparation method thereof

Abstract

The invention discloses a down fabric and a preparation method thereof, and belongs to the field of textile and garment. The preparation method comprises the steps of: subjecting lining fabric to a local gluing process such that stripes of bonding layers are distributed on one side of the lining fabric at intervals of a certain distance, the local gluing process comprising: passing the lining fabric between a press roll and a gluing roll with a plurality of strip-type grooves uniformly distributed in the axial direction; laminating the side of the obtained fabric that has the bonding layers with outer fabric, and placing the laminated fabric in a constant-temperature and constant-humidly environment, thereby obtaining the down fabric. The preparation method of the down fabric has the advantages that: by means of hot melting connection, no pollutants such as waste gases are produced during production, and no drying is needed; the process is simple with reduced cost; the obtained down fabric is clear in width of the bonding layers, and not easy to tear apart; the hot melting connection is dotted connection, allowing for formation of numerous micro-voids inside; due to three-dimensional space structure of the voids, the down may be prevented from passing through the bonded position between two tubes, and the permeability is improved.

Description

technical field [0001] The invention relates to the field of textile and clothing, in particular to a down fabric and a preparation method thereof. Background technique [0002] At present, there are two methods for common double-layer down and cold-proof clothing fabrics: (1) when the gray cloth is woven, the warp and weft yarns are interwoven to connect local parts to form a double-layer fabric; The single-layer fabric is partially adhered to form a double-layer fabric. The down fabric is obtained by filling fillers such as down or hollow cotton in the space of the tube formed by the double-layer fabric obtained by the above two methods. [0003] Although the existing technology basically overcomes the problem of the traditional single-layer fabric, when making a gutless down jacket, the quilting line of the inner and outer fabric leaks, but there are also some problems. The double-layer fabric formed by gray fabric weaving, the first 1. There are more or less some gaps ...

AI Technical Summary

Problems solved by technology

[0009] In order to overcome the problems in the prior art that the down fabric is easy to leak down, the process is complicated, it is not environmentally friendly and the adhesion is poor, the present invention adopts a point-shaped hot-melt connection method, and the double-layer composite structure fabric is formed, and the non-connecting parts are double-layered. A certain amount of down or hollow cotton and other fillers are filled in the bile duct of the fabric, which greatly improves the sewing efficiency of the garment and reduces the cost. The size fluctuation problem, the specific technical solution is as follows:
