Abstract: A manufacturing method of an abrasion resistant mesh fabric includes the following steps: a) arranging a gel applying mechanism, the gel applying mechanism having a gel applying roller, and a drive roller and a scraper, which are located by two opposite sides of the gel applying roller respectively and arranged separately from the gel applying roller, polyurethane gel being stored between the scraper and the outer surface of the gel applying roller in a contact manner with the outer surface of the gel applying roller; b) conveying a mesh fabric base material to pass between the gel applying roller and the drive roller in a way that the polyurethane gel clinging to the gel applying roller is applied to one side of the mesh fabric base material; and c) moisture hardening the polyurethane gel applied on the side of the mesh fabric base material at room temperature.

Abstract: Disclosed herein is a hydrogel wound dressing produced by the steps of a) providing an hydrophobic polyol which has six hydroxyl groups, b) providing an hydrophilic diisocyanate obtained by reacting a second diisocyanate with a hydrophilic polyether diol, c) reacting the hydrophobic polyol with the hydrophilic diisocyanate to obtain a first prepolymer which includes 3 to 6 isocyanate groups, d) partially crosslinking the first prepolymer using a crosslinking agent to obtain a second prepolymer, and e) subjecting the second prepolymer to an end-capping reaction with a silane-containing compound to obtain the hydrogel wound dressing.
