WATERPROOFING MATERIALS
Leathers and textiles with high hydrophobicity
The identification of some contact angles allows the wettability of a substrate to be measured, according to the interaction of said substrate with a water droplet. The greater the substrate repellence to the water droplet, the greater the contact angle of the droplet.
MLSE® processed materials show contact angles greater than 130°, which means high hydrophobicity of the treated surface, when the contact angle is zero for untreated materials dye to a total absorption of the liquid by the material.
a) Untreated leather; b) MLSE® treated leather with hydrophobic properties
Waterproofed leather for footwear for professional use (EN ISO 5403-1)
– Penetration time> 60 m
– Water absorption < 20%
MLSE® treatment does not significantly modify the water vapour permeability of processed materials.
Home textiles and upholstery with resistance to surface wetting (EN ISO 4920), up to Spray Rate 5
Textiles with resistance to surface wetting are obtained, assessed by the “spray test” method up to Grade 5, which is the maximum grade in accordance with the Standard.
STAIN RESISTANCE
Home textiles and upholstery with hydrocarbon resistance. (EN ISO 14419), up to Grade 7 (8 being the maximum grade)
FIRE RESISTANCE
Improved fire resistance of home textiles and upholstery
ANTIMICROBIAL PROPERTIES
The MLSE® treatment allows the improvement of the antimicrobial properties of materials. In addition, thanks to the laser and plasma treatment the formation of bacterial biofilm on the surface of treated materials is avoided.
