Abstract

The invention relates to cool viscose which contains mica powder accounting for 3 to 20 wt% of fiber dry basis. The preparation method comprises the steps of: (1) adding surfactant and dispersing agents into the mica bodies to prepare mica slurry with the concentration of 16% to 30 wt%; (2) preparing mucilage glue using bamboo pulp as a raw material, and adding dissolution denaturant in the step of dissolution; (3) mixing the mica slurry with the dissolved mucilage glue with the weight of 5 to 10 times that of the mica slurry; (4) adding the mica slurry after secondary preparation into the ripening mucilage glue according to proportion and stirring uniformly, and then continuously defoaming and filtering to obtain a spinning solution through; and (5) spinning and forming the spinning solution in a coagulating bath with spinning denaturant and spinning dispersing agents, and preparing the cool viscose after sliver drawing and post treatment. The product of the invention has the healthcare effects of ultraviolet radiation resistance, moisture absorption, perspiration removal, and far infrared healthcare, and is specially suitable for producing clothing products of summer clothes.

Description

technical field [0001] The invention relates to the technical field of viscose fiber, in particular to a cold viscose fiber and a preparation method thereof. Background technique [0002] With the improvement of people's living and entertainment levels, outdoor sports have become a fashion, and people have higher and higher requirements for sportswear fabrics, not only requiring comfortable, healthy, and environmentally friendly fabrics, but also requiring fabrics to have functionality for outdoor environments. When the human body sweats during exercise, ordinary clothing will stick to the skin, the sweat cannot be discharged in time, and the blocking rate of ultraviolet rays is only about 70%, which is far from meeting people's health requirements in outdoor sports. Therefore, in order to meet people's increasingly high-grade and functional requirements for clothing fabrics, people are researching and developing various functional fibers that can ensure outdoor sports and h...
