Abstract

The invention provides a desizing agent for viscose-based wood carbon fibers and a preparation and use method of the desizing agent. The desizing agent for viscose-based wood carbon fibers comprises alkali lignin, sodium carbonate alkaline substances, cellulase, pectase, alpha-amylase, alkaline protease desizing enzyme, lecithin, disecoctylmaleate sodium sulfonate, a cetyl trimethylammonium bromide surfactant, isopropyl alcohol and water which are ultrasonically stirred and prepared into microemulsion. The use method comprises the following steps: dipping the viscose-based wood carbon fibers in the desizing agent for viscose-based wood carbon fibers; after fully wetting the viscose-based wood carbon fibers, transferring the viscose-based wood carbon fibers into a supercritical carbon dioxide fluid device; carrying out heating and pressurizing reaction; taking out the viscose-based wood carbon fibers; cleaning the viscose-based wood carbon fibers repeatedly; and drying the viscose-based wood carbon fibers under vacuum to obtain the desized viscose-based wood carbon fibers. The prepared desizing agent is prepared according to characteristics of the viscose-based wood carbon fibers, a microemulsification technology and a supercritical carbon dioxide technology are combined, the purpose of desizing gently and efficiency is achieved, and active groups and microstructures on surfaces of the carbon fibers are seldom injured.

Description

technical field [0001] The invention belongs to the technical field of textile materials, and in particular relates to a desizing agent for viscose-based woody carbon fibers and a preparation and use method thereof. Background technique [0002] Carbon fiber is a high-tech fiber product with fine diameter, developed microporous structure, developed specific surface area, large adsorption capacity, fast adsorption and desorption speed, concentrated pore size distribution, and excellent adsorption capacity for low-concentration adsorbates. , chemical industry, food, sanitation, electronics and electrochemistry have good development prospects. At present, polyacrylonitrile fiber, pitch fiber and viscose fiber are the main raw materials for the production of carbon fiber. However, the raw material of polyacrylonitrile fiber is petroleum energy, and asphalt contains carcinogens. Therefore, in order to reduce production costs, protect petroleum resources, and protect Environmenta...
