Textile

Functional textile materials sometimes require specific properties like flexibility, durability, impermeability and easy cleaning. Certain textiles, leathers or similar flexible materials are joined in a wet-on-wet bonding process.

Polyurethane dispersion raw materials are capable of bonding different fabrics and other fashion materials, even those that are considered to be hard-to-bond. Since polyurethane dispersions are water-based, they have a low VOC content and contribute to a safe working environment.

Common processing methods to apply PUD product on textile materials are heat activated bonding techniques and wet-on-wet bonding. During the wet-on-wet bonding process the adhesive formulated  with Polyurethane Dispersions is applied onto the fabrics which are then joined together in wet conditions. The bond strength develops during water evaporation.

Many products are based on amorphous and elastic polymers. They are suitable for bonding textiles and other porous substrates used e.g. in the wet-on-wet bonding process. They offer high heat resistance without crosslinker and they can also be used to formulate 2-component systems with polyisocyanate crosslinkers to increase the performance of the finished assembly.
