Elvanol T-25 Polyvinyl alcohol DuPont Polyvinyl alcohol (PVOH) ADHESIVE Elvanol® T-25 is a unique copolymer polyvinyl designed specifically for use as a warp size for spun yarns. Supplied as a white, granular solid, it slurries easily in cold water without lumping and dissolves readily on heating. Solutions of Elvanol® T-25 are stable, noncorrosive, and nontoxic. Elvanol® T-25 as supplied can be stored indefinitely without lumping, molding, or deteriorating. Since solutions of Elvanol® T-25 do not gel or mold, they can be stored over weekends and shutdown periods without impairing their usefulness. The rapid growth of synthetic and blend fabrics has brought with it the need for improved warp size materials having better adhesion, especially to the hydrophobic synthetic fibers. Elvanol® T-25 is a unique copolymer polyvinyl alcohol developed especially for use as a warp size for polyester/ cotton blends and other spun yarns. Alone or in combination with starch, Elvanol® T-25 is being used successfully on practically every type of spun yarn now on the market; including acetate, acrylic, cotton, wool, nylon, and polyester spuns and such blends as polyester/cotton, polyester/wool, and polyester/ rayon. Size bath formulas based on Elvanol® T-25 are simple and easy to prepare, and run without difficulty on the slasher. Important performance advantages of Elvanol® T-25 as a warp size include the following: Low Add-on High Weaving Efficiency Low Weave Room Humidity Excellent Size Bath Stability Ease of Desizing Favorable Cost Performance Polyvinyl alcohol copolymer. Developed for use as a warp size for spun yarns. Offers good adhesion, especially to the hydrophobic synthetic fibers.
