Abstract

The invention discloses a method for preparing flame retardant viscose fiber. The method comprising the following steps: A) mixing nano fiber having a flame retardant function, basic magnesium sulfate whisker, basic magnesium chloride whisker and magnesium salt whisker, then roasting the mixture in an oven of 400 DEG C, carrying out dispersion in absolute ethyl alcohol containing sodium hexametaphosphate, carrying out plasma treatment at normal pressure, carrying out ultrasonic dispersion and cleaning, filtering by a filter of 400 meshes and drying; B) uniformly mixing and drying the whisker and a titanate coupling reagent, adding and mixing antimonous oxide, hexabromocyclododecane, (HDPE+SEBS)-g-MAH and calcium stearate, and then adding cellulose spinning viscose to prepare flame retardant cellulose spinning viscose; and C) preparing the flame retardant viscose fiber by means of a wet or dry process spinning technology. The flame retardant viscose fiber is good in strength, stiffness, abrasive resistance and flame retardance.

Description

technical field [0001] The present invention relates to a method for producing flame retardant viscose fiber. The flame retardant viscose fiber includes cellulose spinning viscose, basic magnesium sulfate whisker, magnesium salt whisker, basic magnesium chloride whisker, three Antimony oxide and hexabromocyclododecane belong to the technical field of textile fiber manufacturing. Background technique [0002] Viscose fiber is a regenerated cellulose fiber. It is made of natural cellulose as raw material, which is made into spinning viscose through alkalization, aging, yellowing and other processes, and is made by wet spinning. Viscose fiber has the structure and properties of cellulose. Good hygroscopicity, air permeability, softness, comfortable to wear; smooth and cool, antistatic and other characteristics, its fabrics are comfortable to wear, hygienic, chic and bright, and have properties that many fibers cannot match. With the improvement of people's living standards a...
