Problems solved by technology

[0002] With the improvement of human living standards and the continuous development of science and technology, the demand for functional fibers and their fabrics has been increasing in recent years, and various types of functional fibers and fabrics have come out one after another. Among them, pearl protein functional synthetic fibers with health care functions (Chinese Patent Publication No. CN1450212A), "Pearl protein functional synthetic fiber and its manufacturing method" applied by Tianjin Saiyuan Health Products Co., Ltd. on April 10, 2002, discloses a pearl protein functional synthetic fiber and its manufacturing method , The process route of synthetic fibers determines that the content of functional substances in the fibers is generally about 4%, and the process is complicated (two-step process), and the spinnability is limited to a certain extent; synthetic fibers have poor permeability and air permeability. It is difficult to release the functional substances inside the fiber after being made into a fabric, which has a certain impact on the comfort of the human body and is difficult to be accepted by people.

Abstract

The invention provides diatom-based viscose fiber. The diatom-based viscose fiber comprises the following components in percentage by weight: 95.5-97% of alpha cellulose and 3-4.5% of diatom-based powder particles. The diatom-based viscose fiber is diatom-based viscose short fiber or diatom-based viscose filament fiber. The invention also provides a preparation method of the viscose fiber; the diatom-based viscose fiber prepared by the method has the functions of absorbing moisture, releasing moisture, adjusting environment humidity, resisting bacteria, deodorizing and removing odor.
