Abstract

This invention discloses a compound fiber new-type slurry pulp and it's making method. The compound fiber new-type pulp is composed of the materials that are two or more than two among velveteen, wood, hemp, bamboo. The making steps as follows: brewing, washing, syringing, beating, mixing up, removing impurities and washing, preparing acid, preparing chlorine, bleaching, acid dealing, removing impurities and washing. This invention can satisfy various needs of the pulp material for viscose.

Description

technical field [0001] The invention relates to a novel composite cellulose pulp used in the textile field and produced by using natural cotton and wood raw materials and a manufacturing method thereof. Background technique [0002] With the continuous improvement of living standards, people's requirements for clothing have shifted from meeting the needs of warm and beautiful clothing to the pursuit of comfort, environmental protection and health. All are to adopt single cotton pulp, wood pulp, bamboo pulp, hemp pulp to manufacture viscose fiber at present. [0003] However, the viscose fibers produced from single raw materials such as cotton pulp and wood pulp have monotonous performance and lack of individuality. The performance is different and has its own characteristics, such as skin affinity, fiber stiffness, antibacterial and antibacterial functions, Fiber softness, deodorization, air permeability, coloring, resilience, moisture absorption and release, etc. Therefore...
