Abstract
Internal softness and surface smoothness are obtainable for textiles on treating them with a composition containing amino-functional polyorganosiloxanes. The composition may be prepared by simply mixing two separately prepared polysiloxane emulsions. Each emulsion contains an amino-functional polyorganosiloxane having a certain minimum content of nitrogen. One of the two separately prepared emulsions is a macroemulsion, the other a microemulsion.
Claims16
A composition obtainable by combining a first aqueous dispersion A), which contains an amino-functional polyorganosiloxane, with a second aqueous dispersion B), which contains an amino-functional polyorganosiloxane, said polyorganosiloxane in said dispersion A) having a nitrogen content of at least 0.1% by weight and said polyorganosiloxane in said dispersion B) having a nitrogen content of at least 0.01% by weight, said dispersion A) being a microemulsion and said dispersion B) being a macroemulsion.
