Problems solved by technology

For example, in the molecular structure of polyester, hydrophilic groups such as ether bonds, hydroxyl groups, and sulfonic acid groups are introduced, and graft copolymerization is carried out on macromolecules, thereby enhancing the hygroscopicity of polyester. Modified polyester through graft copolymerization , the moisture absorption rate can reach 4%~13.4%, but it has not been industrialized due to high cost
[0006] Although the research on cotton-like polyeste

Abstract

The invention discloses an anti-UV cotton-imitated polyester-polyamide composite superfine fiber. The fiber includes superfine cotton-imitated polyester fiber and modified polyamide fiber. The superfine cotton-imitated polyester fiber is used as a core wire, and modified polyamide fiber coats on the outer side of the superfine cotton imitated polyester fiber. The superfine cotton- imitated polyester fiber consists of polyester fiber and a modifier; and the modified polyamide fiber is obtained by adding a graphene nano powder material into polyamide fiber under the active catalysis of a cerium oxide nano powder. Through experimental tests, the anti-UV cotton-imitated polyester-polyamide composite superfine fiber obtained by the invention has infrared emission rate of more than 90% in room temperature wavelength of 2-16; zinc oxide and diphenyl ketone are used to enhance the anti-ultraviolet ability of the polyester fibers; the zinc oxide coverage in the fiber surface layer reduces the absorption surface; and the addition of graphene in modified polyamide fiber increases the flexibility and tensile property of polyamide fiber.

Description

technical field [0001] The invention relates to a fiber production technology, in particular to an anti-UV cotton-like polyester-nylon composite superfine fiber and a production method. Background technique [0002] Cotton fiber has excellent hygroscopicity, softness, and warmth retention, and its fabric has excellent wearability, but there are problems in moisture permeability, dehumidification, waterproof, antifouling, and mildew resistance. [0003] Polyester fibers have a crisp appearance and good thermal stability, but their hygroscopicity is slightly poor. They are mainly used to make various clothing items, bedding items, and interior decoration items. [0004] Cotton-like polyester has both the excellent characteristics of cotton and polyester mentioned above. Generally speaking, it has the following characteristics: it looks like cotton (visual), feels like cotton (tactile), wears like cotton (affinity, comfort), It is more convenient to use than cotton (washable a...
