A METHOD OF PRODUCING URETHANE RESIN FOR ARTIFICIAL LEATHER

摘要

The polyurethane resin for a synthetic leather having a good moisture permeability is produced by covering an adhesive on the outer layer of the polyurethane resin, bonding the adhesive-covered layer to the fiber substrate, and taking the releasing paper off to form an polyurethane layer on the fiber substrate. The polyurethane resin for the outer layer contains pref. polyethylene glycol, polypropylene glycol, polyethylene adipate glycol or polybutylene adipate glycol. The polyethylene resin for the adhesive contains perf. polyester glycol and/or polyether glycol.
