Definitions
- textile treatment agents which are produced by reacting C 10-22 fatty acids with polyamines and neutralization with a non-oxidizing inorganic acid, with aminoethyl ethanolamine being preferred as the polyamine and phosphoric acid being preferred among the inorganic acids and described in the examples.
- the acid is used in a defined amount, which is 0.7 to 1.3 acid equivalents per amine equivalent (EP-A-0230910, page 3, line 17), ie in an amount necessary for the dibasic phosphorous acid to achieve an acidic pH -Not enough.
- EP-A-0230910 is mainly concerned with preventing discoloration or yellowing Textile material, which after finishing, e.g. with a plasticizer, through a final Heat treatment, in particular by a thermosol treatment, as is customary for synthetic fibers, is caused immediately, so that the heat-set material more yellowish or brownish appears.
- DE-A-196 03 401 discloses preventing denim from yellowing when stored. According to DE-A-196 03 401, a peroxy compound is applied in conjunction with a plasticizer from an aqueous solution for this purpose.
