Water Soluble Unsaturated Polyester Resin for Coating and Sizing
Textile Grade Water-Soluble Polyester Resin for Yarn Sizing
Water-soluble polyester chip is entirely water-based polyester resin with high stability and can be 100% dissolved in water without alcohol or other solvents.Water-soluble polyester resin is mainly used as Sizing Chemical for Textile, because of the similar structure with terylene.The sizing operation is the link between yarn making, weaving, and finishing in the textile industry. The process of applying protective adhesive coating on the surface of yarns is known as sizing. Sizing chemicals are mainly applied to warp yarns to improve their performance during the weaving process as warp yarns.Water-soluble polyester resin can be used in the yarn with at least 15% of polyester, like pure polyester filaments(FDY, DTY, POY), staple fibers, polyester and cotton compact yarn, polyester and viscose compact yarn.
Characteristics:
