摘要:
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.

POLYADDITION PRODUCTS ARE PREPARED BY REACTING EPOXIDES WITH BASIC POLYAMIDES IN AN EQUILVALENT RATIO OF 1:1 TO 1:5. THE POLYAMIDESW ARE FROM POLYMERIC UNSATURATED FATTY ACIDS AND POLYALKYLENT POLYAMINES. THE REACTION IS CARRIED OUT IN THE PRESENCE OF ORGANIC SOLVENTS AT AT MOST 80*C. NO LATER THAN AFTER COMPLETION OF THE REACTION, IT IS ENSURED THAT A SAMPLE OF THE REACTION MIXTURE HAS A PHVALUE OF 2 TO 8 AFTER DILUTIOIN WITH WATER. THE RESULTING POLYADDITION PRODUCTS ARE SOLUBLE OR DISPERSIBLE IN WATER AND ARE USEFUL IN THE TEXTILE INDUSTRY E.G. FOR RENDERING WOOL NON-FELTING OR FOR RENDERING TEXTILES WATER REPELLENT, WHEN APPLIED IN COMBINATION WITH SILICONE OILS.
摘要:
Stable preparations of modified aminoplast precondensates are provided, which are prepared by reacting aminoplast precondensates containing alkyl-ether groups with basic polyamides. The polyamides are made from polymeric unsaturated acids and polyalkylene polyamines. The reaction is carried out in the presence of organic solvents at 20* to 100* C. Not later than after completion of the reaction, it is ensured that a sample of the reaction mixture has a pH-value of 2 to 8 after dilution with water. The resulting reaction products are soluble in water and are useful in the textile industry e.g. for rendering wool nonfelting. Especially suitable are the preparations when applied in combination with a dyeing process.

A stable preparation of reaction products is provided which is prepared by first reacting a liquid polyglycidyl ether of a polyphenol with an aliphatic di-primary diamine and thereafter further reacting the resulting adduct with an epoxy compound. The ratio of epoxide group equivalents to amino group equivalents in the first stage is 1:3 to 5.5 and in the second stage 1:2 to 5. The 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.

A PROCESS FOR DYEING NATURAL NITROGENOUS FIBERS WITH WATER-SOLUBLE 1:2 METAL-COMPLEX DYESTUFFS WHEREIN DYEING IS PERFORMED AT 70 TO 85*C. IN THE PRESENCE OF (A) A WATER SOLUBLE SALT OF TETRABORIC ACID AND (B) A NITROGEN CONTAINING POLYGLYCOL DERIVATIVE OF AN ALIPHATIC COMPOUND OF HIGH MOLECULAR WEIGHT IN THE FORM OF AN ACID ESTER OF AN AT LEAST DIBASIC OXYGEN ACID OR A SALT THEREOF.
