Abstract

The invention discloses a new composite fiber pulp and making method, which adopts the following random two or more combination as raw material: cotton velvet, hemp, wood, bamboo. The preparing method comprises the following steps: adjusting material; washing material; washing; beating; fluffing; blending; removing impurities; washing; preparing acid; preparing chlorine; bleaching; proceeding acid disposal; removing impurities; washing; filtering. The invention integrates the superiority of cotton and bamboo fiber material, which satisfies different needs of pulp.

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 bamboo 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 bamboo pulp have monotonous performance and lack of individuality. The performance is different and has its own characteristics, such as carnosine affinity, fiber stiffness, antibacterial and antibacterial functions, Fiber softness, deodorization, air permeability, coloring, resilience, moisture absorption and release, etc. ...
