Problems solved by technology

Seaweed fiber has typical excellent properties such as good biocompatibility, high hygroscopicity, biodegradation and high oxygen permeability. In addition, it also has excellent antibacterial and antibacterial properties. The preparation of fibers containing seaweed extracts The fields of civilian clothing, daily chemicals and hygiene products have huge market application prospects, but in the preparation process, it was found that the extraction efficiency of seaweed extract is low, and at the same time, it is prone to carbonization and deterioration during the preparation process, which affects the quality of the product

Abstract

The invention provides a preparation method of a seaweed polyester long fiber. The content of a seaweed extract in the polyester long fiber is 0.1-3%. The preparation method of the polyester long fiber comprises preparation of the seaweed extract, preparation of a functional modifier containing the seaweed extract, preparation of polyester functional particles, and mixing and spinning forming; according to the seaweed polyester long fibers prepared by the method, the extraction rate of the effective component which refers to algal polysaccharide sulfate substance in the seaweed is highly improved; meanwhile, the polyester long fibers have high hydrophilicity and hygroscopicity, and can achieve the antibacterial rate of 95.0-97.5% on bacteria, such as staphylococcus aureus, escherichia coli, candida albicans and the like which are easily infected by a human body; the polyester long fiber is 0.3-0.5dpf in monofilament fineness; the dry breaking strength of the fiber reaches 6.5-6.8cN / dtex; the wet break strength is 5.2-5.3cN / dtex; and the elongation at break is 32-36% and the comprehensive performance is excellent.

Description

technical field [0001] The invention belongs to the technical field of spinning, and in particular relates to a seaweed polyester long fiber and a preparation method thereof. Background technique [0002] The scientific name of polyester is polyethylene terephthalate fiber, referred to as polyester fiber, and polyester is the trade name of this fiber in our country. It is a fiber-forming high polymer-polyethylene terephthalate (PET) prepared from purified terephthalic acid (PTA) and ethylene glycol (EG) through esterification and polycondensation reactions. The fibers made by spinning and post-processing have a wide range of applications in the field of clothing fabrics. [0003] Seaweed is a pure natural marine biological product, which contains alginic acid, crude protein, multivitamins, enzymes and trace elements. Seaweed fiber has typical excellent properties such as good biocompatibility, high hygroscopicity, biodegradation and high oxygen permeability. In addition, i...
