Document Type and Number:
WIPO Patent Application WO/2024/008053
Kind Code:
A1
Abstract:
A manufacturing method for antimicrobial and anti-yellowing ZnO antimony-free polyester fibers. During a direct spinning process of an antimony-free polyester melt, an anti-yellowing nanometer antimicrobial agent is introduced into a polymerization process of antimony-free polyester, so as to prepare antimicrobial and anti-yellowing ZnO antimony-free polyester fibers. The anti-yellowing nanometer antimicrobial agent is nano-ZnO, which is surface-deposited or surface-coated with phosphate ester micromolecules having a thermo-oxidative degradation resistance function; the phosphate ester micromolecules and the nano-ZnO are bound via Van der Waals force, a hydrogen bond or a covalent bond; and the molecular weight of the phosphate ester micromolecules is 500 Da or less. The content of nano-ZnO in the antimicrobial and anti-yellowing ZnO antimony-free polyester fibers is not lower than 1.2 wt%, and the value of the yellowness index (YI) of the antimicrobial and anti-yellowing ZnO antimony-free polyester fibers is not higher than 16.1. The manufacturing method is simple and is broad in terms of application range; and the prepared antimicrobial and anti-yellowing ZnO antimony-free polyester fibers have good antimicrobial and deodorizing functions, do not turn yellow, and have good strength and laundering durability.
