Embodiment

[0028] Preparation of polybutylene succinate: the raw materials are butanediol and succinic acid, the molar ratio of addition is 1.13, the catalyst is sulfamic acid and tetrabutyl titanate, and the synthesis of polyester mainly includes esterification and polycondensation. 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 and final polycondensation. In the synthesis of polybutylene succinate, catalysts, matting agents, stabilizers, synergists and flame retardants should be added. The amount added is the molar amount of butanediol, the catalyst and the polymerization raw materials enter into the esterification reaction together, and the matting agent, stabilizer, synergist and flame retardant are added in the final stage of the polycondensation reaction.

Abstract

The invention relates to vinylon and poly(butylene succinate) sheath-core fiber, which is characterized in that the sheath-core bicomponent fiber is prepared by the following steps: jointly spinning poly(butylene succinate) obtained through polymerization with vinylon, wherein the poly(butylene succinate) is used as the cortex, the vinylon is used as the core layer, and the cortex totally wraps the core layer, the weight of the cortex accounts for 20-60 percent of the total weight of the fiber, and the linear density of the finished fiber is in the range of 50-200dtex.

Description

technical field [0001] The invention relates to the field of bicomponent fiber preparation, in particular to a sheath-core fiber of vinylon and polybutylene succinate. Background technique [0002] With the improvement of people's living standards, people also have a huge demand for new textiles with high technology content that are healthy, comfortable and environmentally friendly. The research and development of new products and new processes in the textile industry has formed a new development trend: from the innovation of applied technology to the innovation of textile raw materials, and promote the further innovation of applied technology; from the improvement of natural fibers and chemical fibers to the development of biological The innovation of recycled synthetic new fibers is on the scene; process equipment is rapidly updated, and biological organic dyes and chemicals are replacing inorganic dyes and chemicals. As a degradable polymer, polybutylene succinate has a ...
