Rosemary cellulosic fibers and preparation method thereof

Abstract

The invention provides rosemary cellulosic fibers. The content of rosemary extract is 2.7 to 4.8 percent, the dry breaking strength is 4.5 to 5.6 cN / dtex, and the wet breaking strength is 3.6 to 4.1 cN / dtex; and the average sound absorption coefficient under a medium-low frequency is 0.40 to 0.42, the removal rate for hydroxyl radicals is 78 to 81 percent, and the removal rate for hydrogen peroxide is 77 to 80 percent. The invention also provides a preparation method of rosemary cellulosic fibers. The preparation method comprises the steps: preparing a composite coordination agent, preparing amodifier, mixing, spinning, and performing the after-treatment. By adopting the rosemary cellulosic fibers, the free radicals can be eliminated; the rosemary cellulosic fibers have antioxidation performance; after being washed with water for multiple times, good antibacterial performance can still be maintained, and the sound absorption noise reduction effect is excellent; the radiation resistance is excellent, and the application prospect is wide; and the mixing step time can be reduced by 50 percent or more, and the production efficiency can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of textile materials and relates to a textile product, in particular to a rosemary cellulose fiber and a preparation method thereof. Background technique [0002] Cellulose fiber is also called man-made fiber, mainly including viscose fiber, acetate fiber, cupro fiber, etc., which is made of natural materials such as cotton linters, wood, bamboo, bagasse, reed, etc. derived from molecular remodeling. [0003] Patent application number CN201480023835.7 provides a highly permeable crimped fiber with enhanced fiber strength, which has relatively high curl, kink level, wet tensile strength and bulk density value. The patent of application number CN201410081956.9 provides a kind of cellulose fiber and its preparation method, using soluble silver salt, under the action of Lewis acid catalyst, golden yellow regenerated cellulose fiber or regenerated cellulose obtained by catalytic nano chemical plating technology...

Problems solved by technology

The patent of application number CN201410081956.9 provides a kind of cellulose fiber and its preparation method, using soluble silver salt, under the action of Lewis acid catalyst, golden yellow regenerated cellulose fiber or regenerated cellulose obtained by catalytic nano chemical plating technology Fiber fabric, the fiber or fabric has the functions of antibacterial, deodorizing, antistatic, and anti-electromagnetic radiation; but so far, there has not been a kind of sound absorption and noise reduction function, excellent antibacterial effect, ability to scavenge free radicals and anti-radiation properties. The combined effect of cellulose fibers

[0004] At the same time, in the conventional technology, especially when it is necessary to add the extract to prepare the functional cellulose fiber, in order to improve the spinnability of the fiber as much as possible and reduce the occurrence of broken ends, the conventional technology will try to prolong the mixing time to achieve a uniform mixing. purpose, therefore, resulting in a substantial reduction in production efficiency
