Abstract

The invention relates to a cooking aid for preparing chemical fiber pulp and belongs to the field of the preparation of the chemical fiber pulp in textile industry. The invention aims to solve the problem the cooking aid cannot be used for cooking the chemical fiber pulp and is not environment-friendly enough in the cooking technology and the like, and provides the cooking aid for preparing the chemical fiber pulp. The aid comprises the following components in percentage by weight: 3 to 20 percent of sodium sulfite, 1 to 10 percent of magnesium sulfate, 30 to 60 percent of tetrahydro anthraquinone, 5 to 30 percent of sodium dodecyl benzene sulfonate, and 1 to 10 percent of ligninases. The aid can emulsify and remove wax, protein and fat in the cooking of the chemical fiber pulp, improve the penetration and dispersion of cooking medicinal liquid, control the degradation speed of cellulose, improve the content of alp ha cellulose, selectively remove chormophoric groups, improve the half-stuff whiteness and bleachability, reduce life cycle cost (LCC), improve chemical reaction performance, effectively reduce raw material consumption, and reduce the chemical oxygen demand (COD) and chromaticity of cooking waste liquor and other indexes.

Description

technical field [0001] The invention relates to a cooking aid for preparing chemical fiber pulp, which belongs to the field of chemical fiber pulp manufacturing in the textile industry. Background technique [0002] In the production of pulp for chemical fiber, no matter what kind of raw material wood, bamboo or cotton is used, the cooking process is very important. The quality of cooking directly affects the technological performance of pulp in the process of chemical fiber viscose preparation and spinning. In order to achieve the requirements of reducing polymerization, purifying, improving and improving the reaction performance, the characteristics of heavy steaming and light bleaching are reflected in various existing technological processes, so it can be seen that the cooking process plays an important role in the production of chemical fiber pulp . [0003] In the existing cooking technology, the cooking aids are relatively simple, some are to accelerate the reaction,...
