Project Description

Water-Soluble Polyester Resin for Textile Stiffening Agent

Stiffener Polymer for Fabric Finishing Process Replacing Acrylic Emulsion

DESCRIPTION
Textile Stiffening Agent is a specialty high-molecular polymer. It is characterized by easy solubility, low viscosity, and good biodegradation. It can be used in the finishing process of fibers (like cotton, polyester, spandex, nylon), and various fabrics. It is currently widely used for finishing interlining fabrics. This stiffening agent can improve the stiffening and thickening effects, and also enhance the fabric’s fastness to a solid color, rubbing fastness, and tearing strength. The textile with a stiffener can remain stiff for a long time and does not lose stiffness under high humidity conditions.
It can also be used as a stiffener and binder on the non-woven fabric surface. Water-soluble polyester stiffening and binding agent can replace PVA, pure acrylic, and vinegar acrylic emulsion.
