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.
