Abstract

The invention provides a kind of cattail viscose fiber, wherein the content of cattail in the cattail viscose fiber is 5-20%. The present invention also provides a preparation method of cattail viscose fiber, the preparation method of cattail viscose fiber comprises the steps of preparing cattail powder mixture; hydrophobic modification step; mixing step; spinning step. The preparation of the cattail powder mixture comprises: adding the cattail powder and the cattail powder denaturant according to the weight ratio of 8:1 to 10:1 into an electric heating mixer, mixing and heating for denaturation, the heating temperature is 50° C. to 100° C., and the mixing time is 25-40 minutes, mix the cattail powder and cattail powder denaturant evenly. The cattail viscose fiber prepared by the invention has better antibacterial properties, the antibacterial properties are bacteriostatic value > 3.1, and the bactericidal value > 2.8, and the cattail viscose fiber prepared by the invention has permanent antifouling and waterproof functions.

Description

technical field [0001] The invention belongs to the field of preparation of artificial fibers, in particular to a Puhuang viscose fiber and a preparation method thereof, and belongs to the field of production and preparation of textile raw materials. Background technique [0002] With the increasing improvement of people's living standards, people have higher and higher requirements for textiles and clothing, especially for functional and health care requirements, such as antifouling, waterproof, antibacterial health care, antistatic, flame retardant and so on. [0003] For functional textiles, it is mainly divided into two categories: one is functional textiles processed by post-finishing, which is widely used due to its simple process and wide applicability. However, such functional textiles also show many problems in the application, such as the durability of the effect and the safety of the extract to the human body. The other category is antibacterial textiles made of ...
