Nippson Textiles Product Information
Nippson polyvinyl alcohol (PVA) are the superior products for textile warp sizing in spun and filament yarn. Providing a protective coating for spun and filament yarn, Nippson 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.

Superior Film-Forming Properties
The film-forming characteristics of Nippson PVA 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 Nippson PVA are needed when compared to starch. The improved toughness and smoothness of yarn, when sized with Nippson PVA, is indicative of good abrasion resistance against reed motion, shedding motion, and high tension on the weave loom.
Weavability:
In order to reduce warp breakages and weft-stops, Nippson PVA are used to improve toughness and smoothness and elasticity of yarns, binding fluffs for good shedding, particularly on spun polyester blended yarns. Nippson PVA are superior to other materials, like starch, because they are stronger and provide the required protection. The excellent weave performance of Nippson PVA allows for advantageous and difficult-to-weave constructions. When Nippson PVA are used instead of starch, shedding on the slasher decreases due to the efficiency of polyvinyl alcohol. This minimizes waste in the weave loom.Nippson PVA Co-polymer:
Recoverable and Environmentally FriendlyThe unique molecular structure of the Nippson PVA C-grade copolymers is extremely chemically stable, and is not hydrolyzed or otherwise chemically altered in the heat and stresses of a size recovery system. Nippson PVA C-grades are not adversely affecting in the desizing process and can be reused, even when washed with sodium hydroxide. Nippson PVA copolymers are degradable in properly designed and operated activated sludge waste water treatment systems. When a size recovery system is installed at the desizing stage, virtually all Nippson PVA is eliminated from the waste water. Nippson PVA C-grades are easily recovered and reused in any type of commercially available ultrafiltration system. Reuse is straightforward, as there is no viscosity change during desizing, ultrafiltration, or storage. High concentrations can be achieved, reducing transportation costs and providing maximum flexibility in reuse of the reclaimed solutions.

Nippson PVA: Single sizing agent for easy preparation and high weaving efficiency
Nippson’s newly developed single sizing agent, Nippson PVA is used successfully on practically every type of spun yarn (Cotton, Rayon, CVC, T/C, T/R, and Viscose). Nippson PVA has excellent water solubility with good dispersion. Because of its uniform size solution, Nippson PVA 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). Nippson PVA is able to achieve low size-add-on, and it’s suitable for fine count yarns (60s and above) with tight construction fabrics.
Properties:

Flexible and excellent elongation
Ease of desizing in hot water
Excellent viscosity stability
Good anti-foaming performance
Economically recoverable and reusable
Biodegradable.
