Embodiment 1

[0046] Such as figure 1 The production process diagram for the down fabric includes the following steps:

[0047] Step 1: The inner layer fabric 1 is subjected to a local gluing process, so that one side is distributed with a bonding layer 3 at a certain distance. The gluing process includes a pressure roller 4 and a rubber roller 5. The inner layer Fabric 1 passes between the two rollers, such as image 3 As shown, the upper rubber roller 5 has a plurality of strip grooves 51 uniformly distributed along the axial direction;

[0048] Step 2: Composite the side of the fabric obtained in step 1 with the adhesive layer 3 on it and the outer fabric 2;

[0049] Step 3: Wind the composited fabric in Step 2 and place it in a constant temperature and constant room environment to obtain the down fabric.

[0050] Such as image 3 and Figure 4 As shown, the area other than the strip groove 51 on the upper rubber roller 51 is a smooth surface 52, and a plurality of grooves 53 are ev...

Embodiment 3

[0080] Such as figure 1 The production process diagram for the down fabric includes the following steps:

[0081] Step 1: The inner layer fabric 1 is subjected to a partial gluing process, so that one side is distributed with a bonding layer 3 at a certain distance. The gluing process includes a pressure roller 4 and a rubber roller 5. The inner layer Fabric 1 passes between the two rollers, such as image 3 As shown, the upper rubber roller 5 has a plurality of strip grooves 51 uniformly distributed along the axial direction;

[0082] Step 2: Composite the side of the fabric obtained in step 1 with the adhesive layer 3 on it and the outer fabric 2;

[0083] Step 3: Wind the composited fabric in Step 2 and place it in a constant temperature and constant room environment to obtain the down fabric.

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 ...
