HYDROPHILIC POLYMER CONTAINING SYNTHETIC LEATHER |
摘要 |
A breathable leather substitute is prepared by dispersing particles of a hydrophilic acrylate or methacrylate polymer through a sheet of a polyurethane and/or vinyl chloride polymer, laminating the sheet to a woven or non-woven fabric and heating the product to swell the hydrophilic polymer particles. The particles on the surface of the sheet are then broken by running the laminate through a sander to give a suede-like finish.
