Title:
BARRIER FABRIC MANUFACTURING METHOD AND BARRIER FABRIC
Document Type and Number:
WIPO Patent Application WO/2018/082454
Kind Code:
A1
Abstract:
A barrier fabric and a manufacturing method therefor, the method comprising the following steps: S1, soaking fabric in a mixed solvent of 8%-12% concentration aminated polyethylene glycol, 8%-12% concentration dimethylol dihydroxy ethylene urea (DMDHEU), 5%-10% concentration polyhexamethylene biguanide and 1.5%-2.5% concentration magnesium dichloride; S2, when the fabric reaches a liquid absorption rate of 60%-80%, removing the fabric from the mixed solvent and placing the fabric into an 80ºC-100ºC drying environment for high-temperature drying for 4-6 minutes; S3, after removing the fabric from the high-temperature drying environment, placing the fabric into a 150ºC-170ºC high-temperature environment to heat for 30-60 seconds, then cooling at room temperature. The present method improves surface characteristics of a barrier fabric, comprising surface free energy and surface roughness, effectively preventing harmful microorganisms from adhering to and growing on a clothing surface, providing an important function of helping to keep clothing clean in a biomedical and health care environment.
