Embodiment Construction

[0026] In terms of parts by weight, 20-30 parts of wood pulp, 20-30 parts of cotton pulp, 60-80 parts of N-methylmorpholine aqueous solution, and 1-10 parts of ultrafine activated carbon were weighed respectively, and the wood pulp, Mix cotton pulp and N-methylmorpholine aqueous solution, and stir for 20-30 minutes at a temperature of 50-60°C and a rotation speed of 100-140r / min to obtain a mixed solution A. Add ultra-fine activated carbon to the mixed solution A, Continue to stir for 15-20 minutes to obtain the mixed solution B. Treat the mixed solution B under reduced pressure at a temperature of 90-120°C for 1-2 hours to obtain a spinning solution. The nozzle is dry sprayed out into the deionized water of the coagulation bath, soaked for 3 to 5 hours, and the semi-finished product is taken out, washed with deionized water for 3 to 5 times, and dried to constant weight at 60-80°C to obtain the composite fiber; Fiber and cotton fiber are mixed at a ratio of 70%: 30% to obtain...

Abstract

The invention relates to a preparation method of an anti-atomization and anti-haze mask material, and belongs to the technical field of fabrics. Wood pulp and cotton pulp are used as raw materials, superfine activated carbon is mixed, and a composite tencel fiber is prepared through blending spinning; a crystal structure of the tencel fiber is not damaged in the dissolving spinning process; the basic structure still belongs to a cellulose molecular structure, and is linear polymers formed by jointing D-glucopyranose ring and beta-1,4-glycosidic bonds, hydroxyl containing a supramolecular structure with obvious fibrils and cellulose can connect a plurality of crystallization regions and amorphous regions to form a whole, so the tencel fiber has higher polymerization degree and fiber strength, the tencel fiber has excellent properties such as high strength, good luster and easy fibrillation, meanwhile, the production process is nontoxic, harmless and pollution-free, a solvent can be recycled, and prepared base cloth has good air permeability, hygroscopicity and biodegradability.

Description

technical field [0001] The invention relates to a preparation method of an anti-fog and anti-fog mask material, which belongs to the technical field of fabrics. Background technique [0002] In recent years, industrial development and environmental pollution have seriously damaged the living environment of human beings, and the global air quality has declined significantly. At present, air pollution has become an important factor that endangers human health. Along with the deterioration of air quality, the phenomenon of cloudy weather increases gradually, and harm constantly increases the weight of. Haze is a general expression of the excessive content of various suspended particulate matter in the atmosphere, especially PM2.5 (fine particles). Haze weather is a common state of air pollution in recent years. It is caused by the interaction between human activities and specific climatic conditions. produced by the effect. Domestic smog is getting worse day by day. The numbe...
