Embodiment

[0014] 1. When preparing polybutylene succinate, the mol ratio of raw material butanediol to succinic acid is 1.14, and the catalyst is p-toluenesulfonic acid and stannous oxalate. The amount of p-toluenesulfonic acid added is 150×10 of the amount of butanediol -6 , the added amount of stannous oxalate is 300×10 of the amount of butanediol -6 , the synthesis of polyester is mainly completed in two steps of esterification and polycondensation. In the continuous polymerization process, the esterification reaction is completed through two esterification kettles under normal pressure and reduced pressure. The synthetic technique of acid butylene glycol ester:

Abstract

A degradable carbon fiber blending fabric is characterized by firstly utilizing an effective synthesis process to obtain a spinnable high molecular weight poly butylene succinate, and then selecting acarbon fiber with spinning specification of 1.56-2.65detx multiplied by 38mm and a poly butylene succinate fiber with specification of 1.56-1.65detx multiplied by 38mm to conduct blending to made thedegradable carbon fiber blending fabric.

Description

technical field [0001] The invention relates to the field of blended fabric processing, in particular to a degradable carbon fiber fabric. Background technique [0002] Today, as people pay more and more attention to environmental protection, people continue to develop new degradable fibers, making their types increasingly diverse, and their applications involve many fields such as medical, clothing, fishery, construction, hygiene, decoration, and industrial processing. Among the degradable fibers, some aliphatic polyesters can be synthesized by chemical processes, which have industrial prospects and are the most researched. The melting point of polybutylene succinate is higher than 100°C, which is a hot research topic at present. However, degradable polyester fiber also has its own shortcomings, such as low melting point, low strength, and difficult synthesis of high molecular weight polyester, which limits its processing and application. [0003] Carbon fiber is a new mat...
