Abstract

A preparation method of polybutylene succinate fiber belongs to the technical field of preparation of functional synthetic fiber by melt spinning. Vacuum drying is carried out on spinning material of polybutylene succinate; matching mixing is carried out on the spinning material of polybutylene succinate and spinning material phase transition material of microcapsule according to mass ratio of (88-100):(12-0) as well as on spinning processing additive and the total mass between polybutylene succinate and phase transition material of microcapsule according to mass ratio of (0.1-0.5):100; melt spinning is carried out at the spinning speed of 500-800m / min; drafting and heat setting are carried out to obtain the polybutylene succinate fiber. The invention has simple device and process, and saves production cost and energy. The polybutylene succinate phase transition thermo-regulated fiber can provide people with garment and products with cosy sensation and thermo-regulating function, and has the characteristics of environmental friendliness and environmental protection simultaneously, thus having wide application range and prospect.

Description

technical field [0001] The invention relates to a method for preparing polybutylene succinate fibers, in particular to a method for preparing phase-change temperature-regulating fibers by melt spinning, and belongs to the technical field of melt spinning to manufacture functional synthetic fibers. Background technique [0002] Phase-change temperature-regulating fibers generally refer to a class of chemical fibers containing phase-change materials. The phase change of phase-change materials or microencapsulated phase-change materials generally refers to melting and crystallization, and the corresponding processes are endothermic and exothermic. Heat, keep the phase transition temperature constant during the phase transition, so that the fiber has the function of intelligent temperature regulation. Textiles made of this type of fiber also have the function of intelligent temperature regulation, so that a microenvironment that makes the wearer feel comfortable can be created w...
