Appretur

• Modification of hydrophilic materials
• Reduced swelling
• Improved physical material properties

Upgrade to first class

 

Finishes are applied to fabrics, textiles, yarns, and fibres to impart the required functional properties. They can be used to improve the surface structure, rigidity, strength, gloss or density of the substrate, but can also function as a hydrophobic, flame-retardant or antimicrobial agent.

 

The treatment of wood-based materials with a hydrophobing agent makes them either water-repellent or at least reduces the water absorption.

 

The effect of the appretur has to be permanent and without any negative side effects. The characteristics of the substrate have to be maintained and may even be improved significantly depending on the application. The appretur treatment is not allowed to have a detrimental effect on the downline bonding processes with different adhesive systems.
