Problems solved by technology

However, the cellulose fibers containing bamboo charcoal produced by people at present have poor adsorption performance and antibacterial performance due to the structure of bamboo charcoal, and when people produce cellulose fibers containing bamboo charcoal, they still use the conventional production methods of cellulose fibers to produce Spinning viscose mainly uses sodium hydroxide, carbon disulfide, etc. as solvents and additives, and needs to yellow, age, and ripen the cellulose used, and involves chemical reagen

Abstract

The invention discloses a bamboo charcoal cellulose fiber and the manufacturing method thereof. The manufacturing method comprises dissolving cellulose in an ionic solution to obtain a spinning stock solution, adding bamboo charcoal to obtain a modified spinning stock solution, and spinning in a coagulating bath together with the ionic aqueous solution. The content of bamboo charcoal nanoparticles is 4-30 percent by weight of the final fiber product. The manufacturing method has the advantages of simple operation, high yield, less environmental pollution, and less hazard to operator. The produced bamboo charcoal cellulose fiber has strong absorbability and good antibacterial and bacteriostatic effects.

Description

technical field [0001] The invention relates to a cellulose fiber technology, in particular to a bamboo charcoal cellulose fiber and a manufacturing method of the bamboo charcoal cellulose fiber. Background technique [0002] Cellulose is a renewable resource that is ubiquitous in nature. It contains a lot of cellulose in trees, cotton, rice stalks, corn and other plants and some bacterial secretions, and has become a viable alternative to petroleum cracking fiber products. recycled resources. And the cellulose fiber that has the active carbon that can absorb peculiar smell in cellulose fiber, also more and more obtains people's favor. The cellulose fiber containing bamboo charcoal particles not only has the function of absorbing peculiar smell, but also emits a light and elegant fragrance, and has the function of antibacterial and antibacterial at the same time. However, the cellulose fibers containing bamboo charcoal produced by people at present have poor adsorption per...
