Abstract
A textile finishing process in which there is employed, as a pH regulator, a compound or a mixture of compounds of formula I ##STR1## in which p is from 1 to 20, R is hydrogen, C.sub.1-3 alkyl or C.sub.1-3 alkyl substituted by hydroxy R' has independently one of the significances given for R or is --CO--R and A is --CH.sub.2 CH.sub.2 --; --CH.sub.2 --CH.sub.2 --CH.sub.2 --; ##STR2##
Claims27
A textile finishing process in which there is employed, as a pH regulator, a compound or a mixture of compounds of formula I ##STR7## in which p is from 1 to 6,
- R is hydrogen, C.sub.1-3 alkyl or C.sub.1-3 alkyl substituted by hydroxy
- R' has independently one of the significances given for R or is --CO--R and
- A is --CH.sub.2 CH.sub.2 --;
- --CH.sub.2 --CH.sub.2 --CH.sub.2 --;
- ##STR8##
In a textile finishing process wherein a textile substrate is treated with a finishing medium containing (1) a textile finishing agent which requires acid conditions to perform its finishing function or become fixed on the substrate and (2) a compound which regulates the pH of said medium by hydrolizing to an acid therein, the improvement which comprises employing as the pH regulating compound a compound or mixture of compounds of formula I ##STR9## in which p is from 1 to 6 ;
- R is hydrogen, C.sub.1-3 alkyl or C.sub.1-3 alkyl substituted by hydroxy;
- R' has independently one of the significances given for R or is --CO--R;
- and
- A is --CH.sub.2 CH.sub.2 --;
- --CH.sub.2 CH.sub.2 --CH.sub.2 --;
- ##STR10##
