Problems solved by technology

[0003] However, in the preparation of activated carbon and regenerated cellulose fiber composites, the use of activated carbon is affected by the characteristics of the activated carbon itself, its own hydrophobicity, the viscosity of the cellulose solution, the preparation method of the cellulose solution, and the recovery of the cellulose solvent. Subject to certain restrictions

Abstract

The invention discloses an active-carbon and regenerated-cellulose composite material and a preparing method thereof, and belongs to the technical field of spinning. The preparing method of the active-carbon and regenerated-cellulose composite material includes the following steps that turbid liquid containing treated active carbon and regenerated cellulose are mixed, and mixed liquid containing the active carbon and the regenerated cellulose is prepared; the mixed liquid containing the active carbon and the regenerated cellulose is formed, and the active-carbon and regenerated-cellulose composite material is prepared. The active-carbon and regenerated-cellulose composite material is prepared with the preparing method of the active-carbon and regenerated-cellulose composite material, and in the active-carbon and regenerated-cellulose composite material, the value range of the mass percentage content of the active carbon is 1% to 30%. A self-agglomeration effect of the active carbon canbe effectively reduced, the good adsorption characteristic of the active carbon can also be guaranteed, and the composite material also has the advantages of being degradable in regenerated-cellulosefiber, soft in hand feeling and glossy.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a composite material of activated carbon and regenerated cellulose and a preparation method thereof. Background technique [0002] Activated carbon is a kind of hydrophobic material with black appearance, developed internal pore structure, large specific surface area, strong adsorption capacity and easy agglomeration. As a high-efficiency active adsorption material, it can eliminate odor, purify water, decolorize food, and purify air. It is widely used in environmental protection, medicine, military industry and other fields. Regenerated cellulose material is a regenerated cellulose material made from natural cellulose through a series of complex chemical or physical changes, and its main substance is cellulose. Regenerated cellulose fiber not only maintains the degradable characteristics of cellulose, but also has excellent dyeing performance and silk-like luster. The textile...
