Abstract

The invention relates to a dope dyeing method, and particularly relates to an organic pigment dispersing and anchoring dope dyeing method for ultra-high molecular weight polyethylene fiber, which is used for preparing the ultra-high molecular weight polyethylene fiber. The method is carried out according to the following steps: preparing gelatinous solution, preparing color mother liquor, preparing swelling suspension, preparing gel spun silk, and preparing the ultra-high molecular weight polyethylene fiber. The ultra-high molecular weight polyethylene fiber prepared by the organic pigment dispersing and anchoring dope dyeing method has outstanding mechanical property and produces bright color.

Description

technical field [0001] The invention relates to a stock solution coloring method, in particular to a stock solution coloring method for dispersing and anchoring organic pigments of ultra-high molecular weight polyethylene fibers, which is used for preparing ultra-high molecular weight polyethylene fibers. Background technique [0002] Ultra-high molecular weight polyethylene fibers have a dense structure, long molecular chains with vinyl as repeating units, no active groups, strong chemical inertness, and good tolerance to strong acid and alkali solvents and organic solvents. Polyethylene flexible chains are highly oriented and crystallized during thermal stretching, forming ultra-high molecular weight polyethylene fibers with high bending fatigue resistance, impact resistance, and cutting resistance, which can be used in aerospace, ocean-going ships, Building materials, ordnance, sports equipment, medical and health industries. [0003] Due to the dense structure of ultr...
