Stable preparations for finishing wool
Abstract
Abstract A STABLE PREPARATION OF REACTION PRODUCTS IS PROVIDED, WHICH IS PREPARED BY REACTING A BASIC POLYAMIDE WITH A REACTION PRODUCT OF AN EPOXIDE AND AN AMINOPLAST PRECONDENSATE, AN AT LEAST DIHYDRIC ALCOHOL, A DICARBOXYLIC ACID OR AN ANHYDRIDE OF A DICARBOXYLIC ACID. THE POLYAMIDES ARE MADE FROM POLYMERIC UNSATURATED FATTY ACIDS AND POLYALKYLENE POLYAMINES. THE EQUIVALENT RATIO OF THE AMINO GROUPS OF THE POLYAMIDE TO THE EPOXIDE GROUPS OF THE EPOXIDE REACTION PRODUCT IS 1:1 TO 5:1. THE PH-VALUE OF THE PREPARATION IS FROM 2 TO 8. THE RESULTING PREPARATIONS ARE USEFUL IN THE TEXTILE INDUSTRY E.G. FOR RENDERING WOOL NON-FELTING. ESPECIALLY SUITABLE ARE THE PREPARATIONS WHEN APPLIED IN COMBINATION WITH A DYEING PROCESS.
