Abstract

The invention provides a composite silicon-based flame-retardant viscose fiber and a production method thereof, which belong to the field of viscose fibers. The composite silicon-based flame-retardant viscose fiber provided by the invention consists of the following components in part by weight: 13 to 28 parts of linear silicon-based flame retardant, 3 to 12 parts of auxiliary flame retardant, 2 to 8 parts of silane coupling agent and 52 to 82 parts of raw viscose. The composite silicon-based flame-retardant viscose fiber is obtained by preparing a composite silicon-based flame retardant solution and an auxiliary flame retardant solution, blending the composite silicon-based flame retardant solution, the auxiliary flame retardant solution and the raw viscose and performing conventional spinning, post-treatment, drying and packaging. By the composite silicon-based flame-retardant viscose fiber, the mechanical properties, heat resistance and flame retardance of a flame-retardant viscose fiber are improved; and by the preparation method, the problem of spinnability of the flame-retardant viscose fiber is solved.

Description

technical field [0001] The invention relates to a flame-retardant viscose fiber and a production method thereof. More specifically, the invention relates to a composite silicon-based flame-retardant viscose fiber and a production method thereof, belonging to the field of viscose fiber. Background technique [0002] At present, there are roughly three methods for the production of flame-retardant viscose: 1. Post-treatment flame-retardant modification, generally after the fiber is made or during the production process, the primary fiber is treated with a nitrogen-containing organic phosphate compound, or three Antimony oxide and halogen-containing flame retardants are coated on the surface of the fiber in latex state. This method has a good flame retardant effect, but the washing resistance is poor, and the flame retardant effect cannot last; 2. Graft copolymerization flame retardant modification, sticky Flame-retardant viscose fibers can be obtained by graft copolymerization...
