Abstract

The present invention is composite functional regenerated cellulose fiber with pearl and chitosan and its preparation process. The composite functional fiber consists of cellulose 92 wt%, pearl grain 3 wt% and chitosan grain 5 wt%. Its preparation process includes the steps of adding superfine pearl powder of size below 200 nm and chitosan grain into pulp, preparing regenerated cellulose spinning liquor and wet spinning. The composite functional regenerated cellulose fiber may be used to produce fabric with soft hand feeling, high hydroscopicity and antiseptic and deodorizing health function.

Description

Technical field [0001] The invention belongs to the field of functional materials, and specifically relates to a pearl-chitosan composite functional regenerated cellulose fiber and a preparation method thereof. Background technique [0002] Due to the unique characteristics of cellulose fiber, regenerated cellulose fiber has been occupying a stable share in the fiber market for a long time. There are good development prospects. Especially in recent years, people’s awareness of environmental protection has increased and they advocate green life. Due to its natural degradability, people’s awareness of regenerated cellulose fiber has been further enhanced. With the improvement of people's living standards and the change of consumption concepts, more attention is paid to comfort, safety, and health performance in terms of wearing. The development potential of differentiated and functional cellulose fibers is huge. [0003] At present, there are more than 100 varieties of differentiat...
