Abstract

The invention discloses pearl regenerated cellulose fiber and a preparation method thereof. The pearl regenerated cellulose fiber is prepared by adding a pearl emulsion containing pearl micropowder into soluble glue during the preparation of spinning glue, evenly mixing the mixture, and then performing filtration, defoaming and spinning working procedures, wherein two-bath spinning, plasticizing bath drawing molding and multi-stage drawing molding processes are adopted during the spinning, the pearl content in the fiber is 2 to 10 percent of the mass of alphacellulose, the total mass content of amino acid in the fiber is more than or equal to 0.02 percent, and the fiber contains more than or equal to 12 kinds of trace elements. The production method ensures the even distribution of the pearl micropowder in the spinning glue, can also remove a trace amount of pearl micropowder with large particle size through the filtration, and ensures the spinnability of the prepared fiber; and the mild two-bath spinning, plasticizing bath molding and multi-stage drawing molding processes reduce the loss of the pearl micropowder and ensure the effective content of the pearl micropowder in the fiber.

Description

technical field [0001] The invention relates to a regenerated cellulose fiber technology, in particular to a production process of pearl regenerated cellulose fiber and the pearl regenerated cellulose fiber produced by the process. Background technique [0002] Along with the improvement day by day of people's living standard, the requirement of people to clothing has shifted from keeping warm to comfortable, environmental protection, health care, attractive in appearance direction development. Functional clothing fabrics are a trend in the development of high-tech clothing fabrics in the future. Pearl fiber is made by adding superfine pearl particles into the fiber during fiber spinning by high-tech means, such as pearl regenerated cellulose fiber and some pearl synthetic fibers. Pearl particles are evenly distributed inside and outside the fiber, making pearl The fiber is rich in various amino acids and trace elements, and has good health care properties. But at present ...
