PROCESS FOR THE PRODUCTION OF METHYLOTATED CONDENSATION PRODUCTS OF HIGHER FATTY ACIDS AND POLYALKYLENE POLYAMINES

摘要

This invention relates to the production of condensation products which can be used to impart a soft handle to textiles. A monobasic fatty acid with at least 8 carbon atoms and/or montanic acids is reacted with dipropylene triamine and/or diethylene triamine. At least 40 mol % of the acid must be a straight chain fatty acid with at least 12 carbon atoms. The molar ratio of fatty acid to triamine is about 2:1. Thereafter the resulting product is heated with urea in a molar ratio of product to urea of 1:0.5 to 1:1, and optionally the resulting urea condensate is treated with 1 to 5 moles of formaldehyde by mole of urea condensate. The final product can be made into an aqueous emulsion or organic solvent solution and used in the treatment of textiles to give an excellent and soft handle without yellowing of white textiles or changing the shade of coloured textiles.
