Processing method of down-proof fabric

Abstract

The invention discloses a processing method of down-proof fabric. The invention belongs to the technical field of textile fabric processing. The method comprises a post-finishing step. The post finishing step comprises a water repelling step, a calendaring step, and a drying step. During the water repelling step, the fabric is delivered through a repelling tank containing a solution of a functional auxiliary agent; during the calendaring step, the surface of the fabric delivered through the repelling tank and processed by using a rolling liquid is calendared; during the drying step, the calendared fabric is dried by baking, such that the down-proof fabric is obtained. The method is characterized in that: the functional auxiliary agent comprises raw materials of, by weight: 5.5-6.5 parts of a water repelling agent, 0.8-1.2 parts of a bridging agent, 0.8-1.2 parts of resin, 0.08-0.12 parts of a promoting medium; the pH value of the functional auxiliary agent is 4-5; the pressure and thetemperature of a calendaring roller of a calendaring machine, and the moving speed of the fabric are controlled during the calendaring step; and the temperature of a baking oven, and the moving speedof the fabric are controlled during the drying step. With the method, the down-proof effect is good, and the soft effect, the cold-resistance and the tearing resistance of the fabric can be ensured.

Description

technical field [0001] The invention belongs to the technical field of textile fabric processing, and in particular relates to a processing method of an anti-drill fleece fabric. Background technique [0002] The fabrics suitable for down products such as down clothing and down bedding (duvets, down cushions, down pillows, etc.) are mainly made of natural fibers such as cotton fibers, wool fibers, hemp fibers and chemical fibers such as polyester fibers and acrylic fibers. As known in the industry, the fabric made of cotton fiber has the advantages of ideal moisture absorption, breathability, softness and warmth retention, but it is easy to wrinkle and shrink. And though the lining made of aforementioned chemical fibers has the characteristics of soft touch, its air permeability is not as good as that of cotton fabrics. Furthermore, as is well known in the industry, the textile fabric used for processing down products must have outstanding anti-drilling performance, so as t...

Problems solved by technology

However, this method has the following disadvantages: one, because the sizing material is coated on the surface of the fabric in a passive manner by coating, a stiff film layer will be formed on the surface of the fabric after the subsequent calendering step, The softness of the fabric is significantly reduced; secondly, due to the formula of the rubber compound and / or the problem of the raw material itself, the film layer combined on the surface of the fabric cannot reach the cold resistance that people expect, so that the fabric made of surface coating The use of down products in cold regions is restricted; third, the tear strength is poor
