[0057] (3) The preparation method of insect repellent regenerated cellulose fiber, mainly including the influence of coagulation bath on the structure and tensile properties of primary insect repellent fiber, the improvement of fiber tensile properties, etc.;
[0058] (4) The structure, physical and mechanical properties and insect repelling performance of insect repellent regenerated cellulose fibers.
[0059] The invention uses mint fiber and cellulose pulp as raw materials, uses cuproammonia solution method, and adopts wet spinning to prepare insect repellent regenerated cellulose fiber. The insect-repellent regenerated cellulose fiber developed is one of the important raw materials for the development of insect-repellent textiles.
[0060]The purification of cellulose is to separate cellulose from wax, pectin and lignin to obtain products with higher purity of cellulose. The purification of cellulose mainly includes chemical method and biological method. The biological m...
