Environment-friendly processing technique of ultrathin high-gloss downproof chemical fiber fabric

Abstract

The invention relates to an environment-friendly processing technique of an ultrathin high-gloss downproof chemical fiber fabric. The processing technique sequentially comprises the following steps: (1) performing dyeing drying on a grey fabric with the breadth of a and the normal calendaring temperature of T to lower the a to a-delta a1, wherein delta a1 is more than zero; (2) soaking the grey fabric into impregnation liquid containing functional assistants, fully absorbing the impregnation liquid, then shaping and drying, and drawing till the breadth is equal to a-delta a2, wherein delta a2 is more than or equal to zero and less than delta a1, and the functional assistants at least comprise a protective agent and a smoothing agent; and (3) calendaring the grey fabric at the temperature of T plus delta T and under the pressure of 6-10 MPa, wherein delta T is more than or equal to 0 and less than or equal to 30 DEG C, and the breadth of the grey fabric is reduced to a-delta a3, and delta a1 is less than or equal to delta a3. The prepared fabric solves the problems of hardening, thickening, weight increasing, and non-lasting downproof effect, and can achieve downproof, wind-resistant, breathable and moisture permeable effects under conditions of environment protection and no pollution; besides, the processing technique is simple in operation.

Description

technical field [0001] The invention belongs to the technical field of textile fabric processing, and in particular relates to a preparation process of a chemical fiber fabric, especially an ultra-thin down jacket fabric. Background technique [0002] With the rise of ultra-thin down jackets, an extremely light "pocket down jacket" has entered people's lives, that is, it can be stored in a small pocket after being folded. The bloated and bulky image in winter has met the requirements of being beautiful and not "frozen", and is loved by young people. However, the biggest problem is that the ultra-light down jacket has no lining and only relies on a layer of fabric to block the down. It is extremely thin, so all kinds of light and thin down jackets have to face the problem of drill down, improve the performance of light and thin down jacket fabrics, improve the anti-drilling effect of the fabric without increasing the thickness and weight of the fabric, and become light and th...

[0002] With the rise of ultra-thin down jackets, an extremely thin "pocket down jacket" has entered people's lives, that is, it can be stored in a small pocket after being folded. The bloated and bulky image in winter has met the requirements of being beautiful and not "frozen", and is loved by young people. However, the biggest problem is that the ultra-light down jacket has no lining, and only one layer of fabric blocks the down. It is extremely thin, so all kinds of light and thin down jackets have to face the problem of drill down, improve the performance of light and thin down jacket fabrics, improve the anti-drilling effect of the fabric without increasing the thickness and weight of the fabric, and become light and thin down jackets Technical problems that the industry needs to solve urgently

This kind of cross-linking reaction can make the fabric obtain different finishing effects, such as wrinkle resistance, wrinkle recovery, non-ironing, anti-shrinkage, improve handle and drape, easy to dry, improve wear resistance and wash fastness of dyes, and have a good effect on pigment printing. The reaction of the product is quite remarkable, but the anti-drilling process used for ultra-thin down jackets also has the problem of increasing the thickness and weight of the fabric, and after the fabric is finished with resin, their elongation at break and abrasion resistance also vary. The decrease of sweat and moisture permeability reduces the wearing comfort
