White Water Soluble PVA Fiber for Papermaking

Introduction of the product

Polyvinyl Alcohol Fiber (also known as PVA Fiber) is a synthetic fiber made from high polymerization of high quality Polyvinyl Alcohol (PVA) and processed using specific advanced technology.

Polyvinyl Alcohol Fiber its main features are high strength high modulus, low elongation, wear-resistant, acid and alkali resistance, weather resistance, and cement, gypsum and other substrates have a good affinity and bonding, and non-toxic, non-polluting, does not damage the human skin, harmless to the human body, is one of the new generation of high-tech green building materials. Polyvinyl alcohol, the raw material for the production of vinyl fiber, is a water-soluble high polymer with properties between plastic and rubber, and is widely used.

Polyvinyl Alcohol Fiber is a synthetic fiber made from spinning polyvinyl alcohol as raw material. This kind of fiber by formaldehyde treatment of polyvinyl alcohol formaldehyde fiber, China called Vinylon, the international said Vinylon. Comparison of low molecular weight polyvinyl alcohol as raw material by spinning the fiber is water-soluble, called water-soluble polyvinyl alcohol fiber. General polyvinyl alcohol fibers do not have the necessary heat and water resistance, the practical application of little value. Polyvinyl alcohol formaldehyde fiber has a soft, warm and other characteristics, especially the moisture absorption rate (up to 5%) in the synthetic fiber varieties is relatively high, so there is synthetic cotton called; but its heat resistance is poor, softening point of only 120 ℃.

Solubility of Polyvinyl Alcohol Fiber
Polyvinyl Alcohol Fiber can be blended with other fibers, and then in the textile processing is dissolved, to get fine yarn high-grade textiles, can also be made without twisting yarn or no weft blanket. Can also be used as a binder for papermaking to improve the strength and toughness of paper. In addition, it can also be used to make special-purpose work clothes, surgical sutures and so on.

Company information

The company's main import and export products include
（1）Catalysts And Auxiliaries：A catalyst is a substance that changes the rate of reaction in a chemical reaction while its own composition and quality remain unchanged after the reaction. A catalyst that speeds up a reaction is called a positive catalyst (Positive Cata-lyst), and one that slows it down is called a negative catalyst (Negative Catalyst) or retardant. Generally speaking, catalysts are positive catalysts.

Auxiliary agent refers to the industrial and agricultural production, especially in chemical production, in order to improve the production process, improve product quality and yield, or to give the product some unique application performance, usually need to add some auxiliary chemicals. It is a large class of important auxiliary raw materials in chemical production, can give the product with special properties, improve the use of finished products; can accelerate the speed of chemical reaction, improve product yield; can save raw materials, improve processing efficiency, widely used in the chemical industry.

（2）Polymers：Polymerisation is the process by which the repeating units that make up a polymer are linked together by covalent bonds.Polymers can exist in different states depending on the phase, conformation and arrangement of their molecular chains. The two main states are amorphous and crystalline. Polymers usually exist in a semi-crystalline form in which amorphous and crystalline phases coexist.
