    • 1. A PROCESS FOR FINISHING WOOLEN MATERIAL, WHICH COMPRISES TREATING THE WOOLEN MATERIAL AT 30 TO 100* C. WITH AN AQUEOUS PREPARATION OF REACTION PRODUCTS OF EPOXIDES, POLYMERIC FATTY ACIDS AND AMINES, SAID PRODUCTS OF EPOXIDES, TAINED BY REACTING (A) A REACTION PRODUCT OF AT LEAST (A'') ONE EPODIXE WHICH CONTAINS AT LEAST TWO EPOXIDE GROUPS PER MOLECULE AND AT LEAST (A") ONE POLYMERIC UNSATURATED FATTY ACID, DERIVED FROM A FATTY ACID OF 16 TO 22 CARBON ATOMS, WITH THE RATIO OF EQUIVALENTS OF EPOXIDE GROUPS TO ACID GROUPS BEING 0.45:1 TO 0.95:1, WITH (B) AMMONIA OR AN ALIPHATIC OR CYCLOALIPHATIC AMINE WHICH IS A PRIMARY, SECONDARY OR TERTIARY AMINE CONTAINING NO NON-BASIC NITROGEN ATOMS, IN THE PRESENCE OF AN ORGANIC SOLVENT, WITH THE RATIO OF EQUIVALENTS OF ACID GROUPS TO HYDROGEN BONDED AMINE NITROGEN, TO TERITARY AMINO GROUPS OR TO AMMONIA BEING 1:1 TO 1:10, WHEREIN THE REACTION BETWEEN COMPONENTS (a) AND (B) IS CARRIED OUT AT A TEMPERATURE IN THE RANGE OF 20 TO 120* C., AND THEN RINSING AND DRYING THE TREATED WOOLEN MATERIAL.

    • 1313072 Antifelting treatment for wool; sizing paper CIBA-GEIGY AG 8 June 1971 [9 June 1970 22 Jan 1971] 19450/71 Headings D1P and D2B [Also in Division C3] Wool is rendered non felting and paper may be sized by treatment with a composition comprising a polyepoxide (I) containing at least two epoxy groups per molecule, a C 12-24 fattyamine (II) and an aliphatic saturated dicarboxylic acid (III) containing at least 7 carbon atoms reacted together to form a stable preparation which by adding (if necessary) ammonia or water soluble organic base has a pH value of 7.5-12 on dilution with water. The following optional ingredients may also be present in the reaction mixture: an anhydride of an aromatic dicarboxylic acid (at least C 8 ) or of an aliphatic mono- or di-carboxylic acid (at least C 4 ), an aminoplast precondensate containing alkylether groups, a C 2-22 aliphatic diol, another polyfunctional compound containing labile halogen, vinyl or ester groups together with at most one acid, nitrile OH or epoxy group. The starting materials are reacted together, e.g. at 80-120‹C in an organic solvent, e.g. ethylene glycol monobutyl ether. I may be a diglycidyl ether of bisphenol A. II may have the formula Me(CH 2 ) x NH 2 in which x = 11-23. III may have the formula HOOC(CH 2 ) v COOH in which y = 5-12. The wool may be pretreated with dichloroisocyanuric acid or a salt thereof. In an example wool yarn is first dyed with a reactive dye in a circulation bath and rinsed. It was then placed in a water containing 41. water and warmed to 40‹C, then 1 Kg. oxalic acid and 0.2 Kg. of a condensate of 1 mol of a C 16-20 fatty amine and 70 mol ethylene oxide was introduced followed by 10 Kg of a product according to the invention. An emulsion formed which was uniformly absorbed on the wool in 20-30 minutes and thereafter the condensation product of tristearoyl ethylene triamine and ethylene oxide was added as softener. The product may be steamed. The treating bath may optionally contain anonyl phenol ethylene oxide condensate, diammonium phosphate and monoethanolamine sulphite.
