Polyester Resin for Textile Sizing
Currently, the four main types of Textile Sizing Agent are modified starch, polyvinyl alcohol (PVA), acrylic binder, and water-soluble polyester resin (WSP Resin). However, the viscosity of starch fluctuates greatly, and its gelatinization performance is poor. PVA is not biodegradable and causes environmental pollution. Traditional acrylic pastes have serious re-adhesion properties, making it difficult for
