Title:
MULTI-CROSSLINKED SUPER-HYDROPHILIC FABRIC AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/227570
Kind Code:
A1
Abstract:
A multi-crosslinked super-hydrophilic fabric and a preparation method therefor. The method comprises: forming PNC by utilizing a Michael addition reaction of branched PEI and 5ACl; and immersing a fabric in a mixed solution of PNC and CS, taking out the fabric and putting same into an oven for a heating reaction, forming a rough PNC-CS crosslinked coating on the surface of the fabric, and repeating the dip coating-heating step for multiple times to prepare the multi-crosslinked super-hydrophilic fabric having the surface rich in amino groups and hydroxyl groups.
