Straight oil compositions for fibrous materials, which provide excellent smoothness and antistatic properties and also have excellent separation resistance, even without compatibilizers, comprise (A) 100 parts by weight of dimethyl polysiloxane having a viscosity of from 3 to 30 cSt at 25°C and (B) 0.5 to 50 parts by weight of a polyoxyalkylene group- terminated organopolysiloxane. The polyoxyalkylene groups of Component (B) have a block structure of polyoxypropylene and polyoxyethylene units, with the former being bonded to the siloxane moiety. Component (A) is preferably a trimethylsiloxy-terminated polydimethylsiloxane.

Compositions d'huiles non miscibles à l'eau pour matériaux fibreux, communiquant d'excellentes propriétés de douceur et d'antistatique et offrant une excellente résistance au décollement, même en l'absence de compatibilisants. Ces compositions renferment (A) 100 parties en poids d'un diméthylpolysiloxane possédant une viscosité de 3 à 30 cSt à 25 degrés C, et (B) 0,5 à 50 parties en poids d'un organopolysiloxane terminé par le groupe polyoxyalkylène. Les groupes polyoxyalkylène du constituant (B) ont une structure séquencée, composée d'unités de polyoxypropylène et de polyoxyéthylène, la première étant liée à la fraction siloxane. Le constituant (A) est de préférence un polydiméthylsiloxane terminé par le groupe triméthylsiloxy.
