Problems solved by technology

[0009] The purpose of the present invention is to solve the problem that the microcapsule-coated phase change material formula and preparation method in the prior art are very complicated, and the obtained microcapsules have uneven particle size, which is not suitable for the production of composite viscose fibers, and has a great impact on the quality of viscose and availability. In order to solve the problem that the spinnability is greatly affected, a cotton, wood, and bamboo composite pulp phase change microcapsule viscose fiber is provided, which greatly simplifies and optimizes the formulation of the microcapsules, and the obtained microcapsules have uniform particle size, which is suitable for composite pulp viscose The production of glue fiber can significantly improve the quality and spinnability of viscose.

Abstract

The invention relates to cotton, wood and bamboo composite pulp phase-change microcapsule viscose and a preparation method thereof, belonging to the viscose field. The phase-change microcapsule comprises 80-250 parts of methyl methacrylate, 80-150 parts of phase change paraffin, 2.5-6 parts of an emulsifying agent, 0.5-1.5 parts of azo initiator, and 300-400 parts of deionized water. According to the invention, cotton, wood and bamboo composite pulp is used for preparing spun-viscose for producing the cotton, wood and bamboo composite pulp phase-change microcapsule viscose, and steps such as alkali steeping, aging, yellowing, dissolving and the like during the viscose production process are optimized. The microcapsule disclosed by the invention has a uniform grain size, is suitable for producing composite viscose and capable of remarkably improving the quality of the viscose and the spinnability with small influence; moreover, the prepared viscose not only has a natural moisturizing and ventilating effect of composite bamboo pulp fiber, but also has the function of accumulating heat and adjusting temperature.

Description

technical field [0001] The invention relates to a viscose fiber and a preparation method thereof, in particular to a cotton, wood and bamboo composite pulp phase-change microcapsule viscose fiber and a preparation method thereof, belonging to the field of viscose fiber. Background technique [0002] At present, a variety of fibers have been developed using renewable resources at home and abroad, among which the most mature technology and the largest consumption are regenerated cellulose fibers, and the most representative one is bamboo fiber. Bamboo fiber is a kind of cellulose fiber extracted from naturally growing bamboo. Bamboo is composed of 40% to 50% cellulose, 30% pentosan and 20% to 25% lignin, the most important of which is Part of it is cellulose, which can be purified or regenerated to obtain corresponding fibers through bamboo processing. [0003] Functional fibers with heat storage and temperature adjustment functions are a pioneering field of production and re...
