Kuraray Poval™ and Elvanol™ polyvinyl alcohol (PVOH) are the superior products for textile warp sizing in spun and filament yarn. Providing a protective coating for spun and filament yarn, Kuraray Poval™ and Elvanol™ allow yarn to be desized in hot water and are more effective than starch. The excellent film-forming capabilities provide protective coatings for spun and filament yarn, yet are still tough enough in abrasion resistance. Our innovative and dedicated team is committed to providing the highest quality of products and services with less environmental impact for our customers in textile industries around the world.

Superb Quality and Service:

We conduct sizing trials, provide yarn analytical reports, and more. Our advanced technology and decades of experience allow us to collaborate with customers to produce breakthrough and inventive textile products. Our products improve productivity and ensure our customers stay ahead of the competition.


As we are a green company, our products are designed to minimize environmental impact with our special PVOH recovery system to reduce environmental wastage efficiently.


We provide accommodating and customized technical service globally for the convenient access of the customers in every corner of the world.

Superior Film-Forming Properties

The film-forming characteristics of Kuraray Poval™ and Elvanol™ PVOH make them ideal for yarn sizing. Their adhesion, toughness, and film strength are reflected in improved physical properties of the sized yarn. Along with superior characteristics, less Kuraray Poval™ and Elvanol™ PVOH are needed when compared to starch. The improved toughness and smoothness of yarn, when sized with Kuraray Poval™ and Elvanol™, is indicative of good abrasion resistance against reed motion, shedding motion, and high tension on the weave loom.

POVETEX™: Single sizing agent for easy preparation and high weaving efficiency

Kuraray’s newly developed single sizing agent, POVETEX™ is used successfully on practically every type of spun yarn (Cotton, Rayon, CVC, T/C, T/R, and Viscose). POVETEX™ has excellent water solubility with good dispersion. Because of its uniform size solution, POVETEX™ penetrates inside the yarn well and has good viscosity stability without any foaming. This enables consistent size-add-on even for high-speed sizing machines (over 100 meters/minute). POVETEX™ is able to achieve low size-add-on, and it’s suitable for fine count yarns (60s and above) with tight construction fabrics.
