Services

Surfactant agents

  • Measure of physicochemical properties (micellarization, humidification, foaming, emulsification, dispersion, etc.)
  • Application of the above products to textile finishing processes. Alterations of textile materials in finishing through the indicated products: dimensional stability, handle, capillarity, softness, colour differences, whiteness, yellowing, absorption kinetics, contact angles, imbibition power, water absorbant power by capillarity, etc.

Textile materials

  • Textile laundering processes, electrokinetic studies (zeta potential). Laundering degradation.

Textile detergency

  • Parameters related to use of surfactants and builders, the laundering conditions and the complementary operations of drying, ironing and softening such as: detergent power, scales, whiteness, colour, dimensional variation, handle, soil redeposition, wash-and-wear assays.

Particle size and stability of emulsions, micro-emulsions and dispersions.
