Abstract

The present invention provides antibacterial, deodorant and efficient deodorizing cellulose fibers and a preparation method thereof, wherein the cellulose fibers have good antibacterial and deodorizing effects through high adsorption opal powder and a pteris multifida poir extract contained in the cellulose fibers, and the finished product fibers can be widely used in the fields of bedding, clothing, and medical supplies. The preparation method comprises: 1) preparing high adsorption opal powder having a particle size of less than 3 [mu]m and meeting viscose fiber production by using a wet grinding method, and mixing with a microcapsule slurry using a pteris multifida poir extract as a core material and using a melamine formaldehyde resin as a wall material to prepare a composite antibacterial and deodorizing agent; 2) preparing a viscose raw liquid by adopting a cellulose slurry meal as a raw material, and adding the composite antibacterial and deodorizing agent accounting for 4-20 wt% of the alpha-cellulose in the viscose to prepare a blended spinning liquid; and 3) spinning the blended spinning liquid, and carrying out subsequent treatment to obtain the antibacterial, deodorant and efficient deodorizing cellulose fibers. The method of the present invention has the simple process, and is suitable for industrial production.

Description

technical field [0001] The present invention relates to a functional cellulose fiber and a preparation method thereof, in particular to a method for preparing cellulose fiber by using high-adsorption opal powder and plant fern grass extract as antibacterial and deodorant agents and using cellulose fiber as a matrix . Background technique [0002] With the continuous improvement of living standards, people have higher and higher requirements for the functionality and comfort of textiles. It is the main development of the cellulose fiber field to vigorously develop new varieties of high-performance and multi-functional cellulose fibers to meet the needs of domestic and foreign markets. direction, and the cellulose fiber with antibacterial, deodorant and high-efficiency deodorization functions is undoubtedly a multifunctional fiber that is urgently needed by the market. [0003] In high temperature and high humidity seasons, in public places with poor air circulation, people o...
