Polyvinyl alcohol fiber can be blended with other fibers, and then dissolved after textile processing to obtain high-grade spun yarn textiles, and can also be made into non-twisted yarn or non-weft blanket. It can also be used in papermaking as a binder to improve the strength and toughness of paper......

High-strength polyvinylalcohol fiber is a fiber obtained by jelly spinning or wet spinning and high-stretching of polyvinylalcohol with a high degree of polymerization.

The main disadvantage of polyvinyl alcohol fiber is poor dyeability, low dyeing amount, and not bright color. This is because the fiber has a skin-core structure and some hydroxyl groups are blocked by acetalization.

PVA fiber for concrete (or mortar) is an ideal environment-friendly cement reinforcement material, because of its unique molecular structure, it has good affinity with cement, and has good alkali resistance and weather resistance.

Anti-cracking and anti-seepage: The fibers are randomly distributed in the concrete (mortar), which can effectively prevent the occurrence and development of cracks and improve the waterproof and anti-seepage ability.

Hydroxypropyl methylcellulose (Hypromellose), also known as hypromellose, is a kind of non-ionic cellulose mixed ether. It is a semisynthetic, inactive, viscoelastic polymer commonly used as a lubricant in ophthalmology, or as an excipient or vehicle in oral medicines. Soluble in water and some solv......
