Industry Grade Polyvinylpyrrolidone PVP K30 For Textile And Dye Application
Polyvinylpyrrolidone (PVP) molecules have a lactam structure that has strong binding forces with hydroxyl, amino, and carboxyl groups, and dyes often contain these functional groups. Therefore, PVP has a strong affinity with general organic dyes, sometimes even exceeding the binding force between dyes and fibers. Therefore, PVP is known as "liquid fiber". By utilizing the property of PVP, the affinity between some hydrophobic fibers and dyes can be increased, thereby improving the dyeability of such fibers
