Flame-retardant finishing fluid applied to blended fabrics containing polyamide fibers and flame-retardant finishing process

Abstract

The invention discloses flame-retardant finishing fluid applied to blended fabrics containing polyamide fibers and a flame-retardant finishing process. The formula of the flame-retardant finishing fluid comprises 400-500g / L of a flame retardant ZR-2, 3-4g / L of a cross-linking agent GX-100, 20-23g / L of phosphoric acid and 20-26g / L of a fiber protective agent DH6500, wherein the fabric is a blendedfabric composed of cellulosic fibers and polyamide fibers; and in the blended fabric, a weight ratio of the polyamide fibers is 40-50%. According to the flame-retardant finishing fluid and the flame-retardant finishing process disclosed by the invention, the treated blended fabric composed of the cellulosic fibers and polyamide fibers achieves an effect of improving the washable and flame-retardant effects, the content of formaldehyde in the flame-retardant finishing fluid is reduced, and odor in the finishing site is greatly alleviated. Meanwhile, tarring of the flame-retardant roasted non-crosslinked flame retardant is greatly alleviated, the cleaning frequency of the baking machine is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of fabric preparation, in particular to a flame-retardant finishing solution and a flame-retardant finishing process for blended fabrics containing polyamide fibers. Background technique [0002] The blended fabric of cellulose fiber and polyamide fiber has the characteristics of high wear resistance, high strength and high wearing comfort, which is a necessity for military clothing. However, due to their flammability, they often bring disasters to us. Special labor protective clothing, military uniforms, etc. put forward strict requirements for heat insulation and fire prevention. From the long-term trend, the demand for flame retardant is one of the basic needs in daily life. [0003] There are two main domestic production methods for washable and flame-retardant C / N blended fabrics: one is to use probenzene for flame-retardant, which has a better flame-retardant effect, but has poor light fastness, and the heat o...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problems of insufficient flame retardant and washable performance of the C / N blended fabrics treated by the existing flame retardant finishing technology, as well as the problems of high environmental odor in the production environment, sticky rolls, and difficult to remove odor after washing, the present invention provides a method for containing The flame retardant finishing liquid of polyamide fiber blended fabrics achieves improved washability and flame retardant effect, and at the same time, the formaldehyde content of the flame retardant treatment liquid is reduced, and the odor of the finishing site is greatly reduced. Lighten, the technical effect of reducing the number of roaster cleaning and improving production efficiency
