Hydrophobizing of fibrous materials with polyorganosiloxanes

摘要

The present invention relates on the use of 1,3-dihydroxyalkyl functionalized polyorganosiloxanes in compositions for the treatment of materials having a fibrous structure, such as leather, furs, textiles and paper. The invention further relates to a process for treating fibrous materials with waterproofing.

主权项

1. A process of treating a fibrous substrate comprising applying a polyorganosiloxane a) including at least one 1,3-dihydroxy alkyl moiety and at least one polyorganosiloxane b)—different from polyorganosiloxane a)—wherein polyorganosiloxane b) includes at least one organic group bound to a polyorganosiloxane backbone via an Si—C-bond, said at least one organic group comprising at least one polar functional group;
or salts of polyorganosiloxane b).
