[0059] (3) The preparation method of insect repellent regenerated cellulose fibers, mainly including the effect of coagulation bath on the structure and tensile properties of primary insect repellent fibers, and the improvement of fiber tensile properties;
[0060] (4) The structure, physical and mechanical properties and insect repelling properties of regenerated cellulose fiber for insect repellent.
[0061] 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.
[0062] 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...
