Title:
PREPARATION METHOD FOR ANTIMICROBIAL KNITTED FABRIC
Document Type and Number:
WIPO Patent Application WO/2022/143004
Kind Code:
A1
Abstract:
A preparation method for an antimicrobial knitted fabric, comprising: adding spandex to a blended yarn formed by blending an antimicrobial polyester fiber and a modal fiber and weaving same to obtain a knitted single-sided fabric, and then successively carrying out pre-setting, pre-treatment, dyeing, dehydration, cutting, drying, setting, and pre-shrinking to obtain the antimicrobial knitted fabric. The antimicrobial knitted fabric comprises the following components in parts by weight: 25-40 parts of the antimicrobial polyester fiber, 50-70 parts of the modal fiber, and 5-10 parts of spandex. The polyester segments of the antimicrobial polyester fiber comprise terephthalic acid segments, ethylene glycol segments and terephthalic acid-2(4-pyridine) segments, and the terephthalic acid-2(4-pyridine) segments of different polyester segments are coordinated by means of Ag+. The N atom on pyridine of the terephthalic acid-2(4-pyridine) segments participates in the coordination. The preparation method uses the coordination technique to make Ag+ be firmly controlled in the polyester fiber, thereby enhancing the antimicrobial and deodorizing efficiency of an antimicrobial agent and the permanence thereof in the polyester fiber, and improving the durability of the antibacterial property. The antimicrobial knitted fabric has excellent properties, and is healthy and environmentally friendly.
