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 reagents such as sulfate, sulfuric acid, and zinc sulfate, but All the above-mentioned organic reagents are volatile, causing serious pollution to the environment and endangering the health of operators; while the inorganic reagents are highly corrosive, which greatly corrodes the equipment.
In addition, the recycling process of these chemical reagents is not only cumbersome in process flow and high in recycling costs, but also produces a large amount of waste gas and waste water, causing serious pollution to the environment

Abstract

The invention discloses a method for manufacturing bamboo charcoal cellulose fiber, which is to dissolve cellulose through ionic liquid to make spinning stock solution, then add nano-bamboo charcoal to make denatured spinning stock solution, and then pass through a coagulation bath made of ionic liquid aqueous solution It is made by spinning, and the content of nano-bamboo charcoal is 4% to 30% of the weight of the finished fiber. The manufacturing method of the invention is simple in operation, high in productivity, less in environmental pollution and less harmful to operators, and the prepared bamboo charcoal cellulose fiber has excellent adsorption performance, antibacterial performance and antibacterial performance.

Description

technical field [0001] The present invention relates to a kind of cellulose fiber technology, especially relate to a kind of manufacturing method of 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 performance and a...
