Abstract
Abstract A cationic compound of the formula [I] below is used for improving the dyeing properties of a textile material by treating therewith the textile material before or after dyeing with an anionic dye. ##STR1## wherein A is a group of the formula [II]: ##STR2## wherein p and q are an integer of 1 to 8, n is an integer of 0 to 2, X is halogen, R 1 , R 2 , R 3 , R 4 and R 5 are (C1-4) alkyl, OH-- or cyano-substituent-having (C1-4) alkyl or (C1-4) alkenyl, and Q 1 , Q 2 and Q 3 are: ##STR3## in which Y is halogen.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
201 words
A method for improving the dyeing properties of a textile material, which comprises treating a textile material composed of a natural fiber, a regenerated fiber, a semisynthetic fiber, a polyvinyl alcohol fiber or a mixture thereof with a cationic compound represented by the following general formula before or after dyeing of the textile material with an anionic dye, an indigo dye or a vat dye: ##STR22## wherein A is a group represented by the following general formula: [II]: ##STR23## in which each of p and q is an integer of 1 to 8, n is an integer of 0 to 2, X is a halogen atom, each of R 1 , R 2 , R 3 , R 4 and R 3 is independently an alkyl having 1 to 4 carbon atoms, an alkyl having 1 to 4 carbon atoms which has at least one substituent selected from the group consisting of hydroxyl and cyano, or an alkenyl having 2 to 4 carbon atoms, and each of Q 1 , Q 2 and Q 3 is independently a group of the following formula: ##STR24## in which Y is a halogen atom and X and Y may be the same or different.
