Polyvinyl Alcohol Usp CAS 9002-89-5

1. Application in woollen fabric market

10% ~ 20% water-soluble Polyvinyl Alcohol Usp fiber tops are combined with wool and spun to make materials, and afterwards the water-soluble fibers are removed in the dyeing and completing stage, which can increase the wool count by around 20%, so regarding get light weight, Soft, cosy, drapeable as well as elastic woollen fabrics.

2. Application in cotton rotating industry

After Polyvinyl Alcohol Usp water-soluble fiber and also cotton are mixed into yarn, it is knitted or woven to make grey fabric, and the PVA water-soluble fiber is eliminated in the post-treatment to get a thin, soft as well as amazing spinning style, wetness absorption and also breathability, and also comfy putting on. and other excellent efficiency. Compared with traditional fabrics that use Xinjiang long-staple cotton and also imported Egyptian cotton as raw materials, supplemented by advanced rotating devices as well as rigorous and also sensible procedure problems, high-count yarns can be spun, which substantially reduces manufacturing prices as well as boosts item top quality. After the core-spun yarn with water-soluble fiber as skin and cotton fiber as the core is utilized to make a towel, then the water-soluble fiber is gotten rid of by warm water therapy. This type of towel likewise has the features of not reducing velvet yet a little glowing, as well as it is a state-of-the-art towel by visual evaluation and hand feeling like a velvet towel.

3. Application of Polyvinyl Alcohol Usp water-soluble filament

Polyvinyl Alcohol Usp water-soluble filament can be liquified in water at 5 ~ 100 ℃, with ideal water-soluble temperature, high toughness, excellent acid and also alkali resistance and completely dry warmth resistance. Weaving PVA water-soluble filament instead of ordinary yarn between two socks to be divided, cancel the procedure of dividing socks by automated separation equipment or scissors. Water-soluble fibers are utilized for textile warp sizing, and also have the advantages of uniform sizing, stable chemical framework, great corrosion resistance, and simple and very easy procedure. After weaving with PVA water-soluble filaments as weft threads, the weft threads are dissolved in hot water to make non-weft felts. The water-soluble non-woven textile can be utilized as the base material for embroidery in the garment industry. After handling, the non-woven textile can be treated in hot water to acquire hollow and three-dimensional embroidery.

4. Application in armed forces

Water-soluble fibers are utilized for surface area mines to obstruct ports or rivers, water-soluble parachutes for airdrop representatives, as well as protective work clothes for nuclear submarine drivers.

At present, my country’s paper sector is confronted with 2 major problems. One is that the quality of this kind of pulp is substantially decreased as a result of the dwarfing of wheat straw and additionally the devastation of reeds; Nevertheless, the top-notch of waste pulp is reduced, along with simply exactly how to guarantee the top quality of paper things as well as reduce prices has actually come to be a difficult problem for paper mills. Including an appropriate quantity of Polyvinyl Alcohol Usp water-soluble fiber to the paper can considerably boost the paper’s durability, damage resistance, folding resistance, tear strength and surface printing durability. The enhancing system is that the PVA water-soluble fiber macromolecules have a large number of hydroxyl groups, which can produce a large amount of hydrogen bonding stress with the pulp fiber, along with can be liquified right into semi-soluble bonding fibers when the paper is dried. The strength of the water-soluble fiber is a whole lot over that of the pulp fiber. As a result, Can considerably enhance the strength of the paper.
