Abstract

The invention discloses a flame retardant viscose fiber and a preparation method thereof. The preparation method of the flame retardant viscose fiber comprises the following steps of adding a flame retardant emulsion into a viscose solution, uniformly mixing, carrying out filtration, and carrying out molding by a conventional wet spinning technology to obtain the flame retardant viscose fiber. A mass ratio of the flame retardant emulsion to the viscose solution is in a range of (1: 100) to (5: 100). The flame retardant emulsion comprises: by weight, 20 to 30 parts of N,N'-di(diphenoxythiophosphoryl)dithioethyldiamide, 5 to 10 parts of tris(2-chloropropyl) phosphate, 10 to 15 parts of cocoamidopropyl betaine, 5 to 10 parts of potassium dodecyl phosphate, 20 to 25 parts of Tween-60, and 500to 800 parts of water. The flame retardant viscose fiber has good flame retardant effects and a high water-retaining capacity.

Description

technical field [0001] The invention relates to a viscose fiber and a preparation method thereof, in particular to a flame-retardant viscose fiber and a preparation method thereof. Background technique [0002] Viscose fiber (viscose fiber) is the full name of viscose fiber. It is divided into viscose filament and viscose staple fiber. Viscose fiber is a cellulose fiber produced from cotton or other natural fibers. Among the 12 main textile fibers, the moisture content of viscose fiber is most in line with the physiological requirements of human skin, and it has the characteristics of smooth and cool, breathable, antistatic, and brilliant dyeing. [0003] Viscose fiber is a regenerated cellulose fiber. It is made of natural cellulose as raw material, which is made into soluble cellulose sulfonate through alkalization, aging, sulfonation and other processes, and then dissolved in dilute lye to make viscose, which is made by wet spinning. Using different raw materials and ...
