Embodiment

[0014] 1. Preparation of polybutylene succinate: the molar ratio of butanediol to succinic acid is 1.10 to 1.15, the catalyst is p-toluenesulfonic acid and stannous chloride, and the addition amount of p-toluenesulfonic acid is butanediol 100×10 of the amount of alcohol -6 , the amount of stannous chloride added is 400×10 of the amount of butanediol -6 In the continuous polymerization process, the esterification reaction is completed through two esterification tanks at normal pressure and reduced pressure, and the polycondensation reaction is completed through two tanks of pre-condensation polymerization and final polycondensation. The matting agent, catalyst and flame retardant used in fiber synthesis are configured together with the raw materials into a slurry and added to the esterification reactor to participate in the reaction, and the stabilizer is added when the precondensation polymer enters the final polycondensation reactor. Synthetic process of polybutylene succina...

Abstract

The invention discloses a polybutylene succinate metal fiber shell fabric which is characterized in that spinnable polybutylene succinate with high molecular weight is obtained by using an effective synthesis process; a metal fiber is selected to blend with the polybutylene succinate; a metal fiber comprises a silver fiber, a copper fiber, a gold fiber, a stainless steel fiber, and the like; and the degradable metal fiber shell fabric is obtained through the procedures of blowing, cotton carding, drawing, spun yarning, weaving, coloring, and the like.

Description

technical field [0001] The invention relates to the field of degradable fabric preparation, in particular to a polybutylene succinate metal fiber fabric. Background technique [0002] As people pay more and more attention to environmental protection, biodegradable polymer materials (plastics, rubber, fibers, etc.) have become a research hotspot in countries all over the world. There are more and more types of degradable fibers, and their applications involve many fields such as medical, clothing, fishery, construction, sanitation, decoration, and industrial processing. Among the degradable polymer materials, aliphatic polyester can be synthesized from chemical raw materials, has industrialization prospects, and is also the most researched. The melting point of polybutylene succinate is higher than 100°C, which is a hot research topic at present. [0003] However, the degradable aliphatic polyester fiber also has its own shortcomings, such as low melting point, low strength...
