Surfactants and Detergency Laboratory

Services

Surfactants products

• Measurement of its physic-chemical properties (mycelium, wetting, foaming, emulsification, dispersion, etc.)
• Application of these products to textile processes of textile ennobling: changes in textiles during their ennobling through these products, dimensional stability, touch, capillarity, softness, colour differences, whiteness, yellowing, absorption kinetics, contact angles, imbibition power, water absorption, power for capillarity, etc.

Textiles

• Textile washing processes
• Electro kinetics studies (zeta potential)
• Degradation by washing

Textile detergency

• Parameters relative to the use of detergent and adjuvant additives, washing conditions and complementary drying, ironing and smoothing operations such as: detergent efficiency, incrustations, whiteness, colour, dimensional variation, touch redepositing of impurities, “wash and wear” tests.
• Stability and particle size of emulsions, micro emulsions and dispersions.

Courses

• Application of surfactants to the textile industry
• Physic-chemical of surfactant products
• Textile detergency
• Colloidal physic-chemical

Lines R+D

• Physic- chemical of surfactant products and textile detergency
• Detergent evaluation and optimization of washing processes
• Application of surfactants to textile ennoblement processes.
• Formation of electrical double layers, electro kinetic phenomena
• Surfactant characterization and its application to interfacial phenomena
