Industrial Polyvinyl Alcohol (PVA) Supplier & Manufacturer

febrero 9, 2026 •

What is Polyvinyl Alcohol (PVA)? Polyvinyl Alcohol (PVA) is a water-soluble synthetic polymer that has become indispensable in modern industrial manufacturing. Unlike many polymers created through direct polymerization of monomers, PVA is manufactured via the hydrolysis (saponification) of polyvinyl acetate (PVAc). This unique chemical origin gives PVA its distinctive backbone structure, characterized by alternating hydroxyl

Aplicación de PVA en el encolado de urdimbre

15 de mayo de 2025 •

El alcohol polivinílico (PVA) es un agente de encolado de urdimbre ampliamente utilizado, valorado por su excelente adhesión a fibras tanto hidrófilas como hidrófobas. Forma películas resistentes a la abrasión y se mezcla bien con otros agentes de encolado como el almidón y el ácido poliacrílico, mejorando así el rendimiento general del encolado. El PVA totalmente hidrolizado ofrece una fuerte adhesión, pero es difícil de disolver y desencolar, mientras que los grados parcialmente hidrolizados son más fáciles de manipular, pero propensos a la formación de espuma. Si bien el PVA no es tóxico, su lenta biodegradabilidad limita su atractivo ambiental. Se están realizando esfuerzos para mejorar su respeto al medio ambiente y adaptar sus propiedades a los requisitos modernos de la tejeduría de alta velocidad. A pesar de estos desafíos, el PVA sigue siendo uno de los materiales de encolado textil más eficaces y fiables que se utilizan actualmente.
