ICI Surfactants has launched the Edunine SM-CS softener for fabric softening in woven cotton and polyester fabrics. The small size of the silicone droplets in this microemulsion enables it to penetrate rougher fabric surfaces further and more efficiently than other softeners formulated as microemulsions, according to ICI.
The increased use of rotor spun yarns has created a demand for improved fabric softeners.
Already textile finishers show a preference for silicone softeners because of their apparently superior performance on such fabrics. Formulation of the silicone as a microemulsion takes the development one step further, claims ICI.
Edunine SM-CS operates without a cross-linking agent and needs no special curing conditions. It can be used with non-ionic, cationic and anionic products. ICI claims that shear stability is exceptionally good for a silicone emulsion. And Edunine SM-CS can be applied by vacuum extraction or foam techniques.
As a microemulsion, with an extremely small particle size, Edunine SM-CS is a clear, colourless, water-white liquid. It is based on a solvent-free, non-ionic emulsifier system and is readily miscible with water. It remains stable even in hard water.
