Abstract

The invention discloses a preparation method of regenerated base antistatic polyester filaments. A high-performance conductive additive is obtained by compounding nano-carbon black with a specific DBP value and graphene, and then mixed with regenerated PET materials for granulation. After high-speed continuous spinning silk is prepared. Nano-carbon blacks with different DBP values ​​are distributed in different regions on the surface of reduced graphene oxide, forming a unique nano-composite structure, showing excellent electrical conductivity, and can be evenly dispersed in PET, which can not only greatly improve the polyester filament Antistatic. At the same time, the addition of graphene can also bring a series of effects such as far-infrared emission, UV protection, antibacterial and mite removal, and can be applied in home textiles, carpets, clothing, masks, medical protective gear and other fields.

Description

technical field [0001] The invention belongs to the field of chemical fibers, in particular to a preparation method of regenerated base antistatic polyester filaments. Background technique [0002] Regenerated polyester is a chemical fiber variety obtained by using waste polyester bottle flakes, spinning waste, polymer waste and pulp as raw materials, after cleaning, and processing. It belongs to the resource recycling project, which can effectively reduce oil consumption and reduce the impact of plastic waste on the environment. Pollution, low cost, good performance and other advantages, especially favored by developed countries in Europe and America, widely used in toys, quilts, home textiles, shopping bags, bags, etc. Re-obtaining chemical fiber products from waste materials also significantly reduces environmental pollution and resource waste caused by the polyester industry. Therefore, recycled polyester fiber has received more and more attention and has become an indi...
