Abstract

The invention relates to halogen-free environment-friendly composite flame-retardant viscose fiber spinning solution and a preparation method thereof and belongs to the field of viscose fibers. The invention aims at solving the problems in the prior art that a flame-retardant agent has large grain size and wide grain size distribution; flame-retardant agent dispersion has bad stability to cause that the flame-retardant viscose fiber spinning solution is nonuniform to disperse, generates the flocculation phenomenon and has single effective flame-retardant component; and the flame-retardant agent has larger additive mount to affect the spinning performance and generate larger effect on the physical property of the spun flame retardant flame-retardant viscose fiber. The halogen-free environment-friendly composite flame-retardant emulsion composed of a water glass and phosphorus-nitrogen flame-retardant agent and a surface active agent has the advantages of no flocculation and stable performance. After being mixed with viscose, the halogen-free environment-friendly composite flame-retardant viscose fiber spinning solution is free from flocculation, has stable performance, is uniform to disperse and has multiple effective flame-retardant components.

Description

Technical field [0001] The present invention involves a sticky fiber spinning solution and its preparation method. More specifically, the present invention involves a kind of halogen -free environmental protection replica and flame retardant sticky glue fiber spinning solution and its preparation method.Essence Background technique [0002] The adhesive fiber has a wide range of uses such as excellent hygroscopicity, easy dyeing, anti -static, easy textile processing.However, the sticky fiber is flammable fiber, which is extremely flawed by the textiles made by it, causing a fire, causing great harm to the people's lives and property, thereby restricting its widespread application. With the improvement of people's consumption level and the enhancement of security awarenessThe call for flame retardant of adhesive fibers is strong, and the research on domestic and foreign sticky fiber is strongly promoted. [0003] The flame retardant adhesive fiber produced by Lenzing, Austria and...
