Abstract: A water-based surface treatment agent is provided. The water-based surface treatment agent is suitable to be coated onto a surface of a synthetic leather. The water-based surface treatment agent at least includes waterborne polyurethane, silicone powder, and water. Based on 100 parts by weight of the water-based surface treatment agent, a content of the waterborne polyurethane is within 15 to 35 parts by weight, and a content of the silicone powder is within 3 to 20 parts by weight. A non-volatile matter content of the waterborne polyurethane is within a range from 20 wt % to 30 wt %. Each grain of the silicone powder has a particle size within a range from 0.2 μm to 15 μm, a specific gravity within a range from 0.9 to 1.5, a water content within a range from 0.1% to 0.5%, and a hardness (A) within a range from 30 to 90.

Abstract: A method for processing a waste fabric containing polyester and cotton fibers includes the following steps. The first step is providing a plurality of fabric scraps each containing polyester fibers and cotton fibers. The next step is allowing an acid catalyst aqueous solution to repeatedly contact and react with the fabric scraps at 130° C. to 160° C. in a circulation and backflow manner, so as to separate the cotton fibers from each of the fabric scraps. The last step is recycling the reacted acid catalyst aqueous solution and fabric scraps.

Abstract: A method for processing a waste fabric containing polyester and wool fibers includes the following steps. The method is to treat the waste fabric with an acid catalyst aqueous solution at 160° C. to 170° C. The wool fibers are degraded and completely separated from the polyester fibers in a treatment process. Afterwards, the polyester fibers are recycled.
