Abstract

The invention discloses a production process of graphene composite three-dimensional spiral hollow fiber. The process is characterized in that graphene particles and polyethylene terephthalate chips are used as raw materials, and the raw material components are subjected to composite spinning according to a mass ratio of (1-9): (99-91). The production process of composite spinning comprises the following ten steps of 1) vacuumizing and drying; 2) preparation of a solution; (3) filament extruding; 4) spinning; 5) cooling and molding; (6) winding and bundling; 7) oil immersion; 8) stretching; (9) high-temperature setting; and 10) packaging and warehousing. The environment-friendly PET chips are adopted as a main body of a composite formula, the number of the graphene particles is controlled, a blended melt is prepared through twin-screw melting, the three-dimensional spiral hollow composite fiber is prepared under a special spinning assembly, and due to the fact that graphene has the spontaneous heating characteristic, underwear and underpants woven from the prepared fiber have the characteristics of health care, antibiosis, deodorization and the like.

Description

technical field [0001] The invention belongs to the technical field of fiber production, and in particular relates to a production process of a graphene composite three-dimensional helical hollow fiber. Background technique [0002] There are a variety of bacteria and molds in the human living environment, common ones include Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Aspergillus flavus and Candida albicans, etc. Staphylococcus epidermidis and coryneform bacteria are common in underwear and underwear, causing The bacteria that cause the peculiar smell of the clothes are generally bacillus spores and a small amount of Staphylococcus epidermidis. In a high-temperature and high-humidity environment, when these microorganisms multiply on clothing, the fibers are easily degraded and discolored by the action of their acidic or alkaline metabolites, and volatile odorous substances such as acetic acid and ammonia gas are generated. Cause some skin diseases of the h...
