Abstract

The invention relates to a preparation method of taxus chinensis viscose fibers. The preparation method is characterized by comprising the following technological steps of: tabletting a taxus chinensis raw material, washing tablets in hot water, and placing the tablets in an alkali liquor for stewing; continuously washing the tablets in hot water after stewing; beating the tablets in a beating machine to obtain pulp, and desanding the pulp; concentrating the pulp in a thickner after desanding, and bleaching the concentrated pulp; continuously concentrating the bleached pulp, manufacturing paper with pulp after concentration, and obtaining the taxus chinensis pulp; soaking the taxus chinensis pulp in a NaOH solution, squeezing after soaking to obtain fine materials, carrying out yellowing treatment on the fin materials to obtain mucilage glue, spinning the mucilage glue in a spinning coagulating bath, and obtaining the taxus chinensis viscose fibers. Taxus chinensis with the anti-cancer effect adopted in the preparation method is made into the taxus chinensis viscose fibers; the taxus chinensis viscose fibers have good spinning processability; manufactured textiles has the advantages of smoothness, fineness and the like, has the functional health-care effect and is beneficial to promoting the sleep.

Description

technical field [0001] The invention relates to a preparation method of viscose fiber, in particular to a preparation method of yew viscose fiber, belonging to the technical field of textile fibers. Background technique [0002] Yew, also known as yew, is known as the "giant panda" among plants. It has a history of 2.5 million years on the earth. Because of its special value integrating medicinal, ornamental, cancer prevention and health care, the State Forestry Administration Therefore, it was listed as a first-class precious protected tree species in 1992. Its whole body is full of treasures. The roots, stems, leaves, skins and seeds all contain paclitaxel, which has a unique anti-cancer mechanism and high anti-cancer activity. It can prevent the proliferation of cancer cells and inhibit the migration of tumor cells. It is recognized as It is the most important anticancer active substance in the field of natural medicine today. The yew tea made from the twigs and leaves ...
