Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
68 words
In the process for dyeing textile materials, yarns, threads or fibers dyeable with reactive dyestuffs by contact and treatment with reactive dyestuff, the improvement comprises improving the fastness of the dyed substrate by aftertreating the dyed substrate with 0.5 to 5% by weight of substrate of an aftertreatment agent which is the reaction product of polyethyleneimine and an alkylating agent having two alkylating groups in an aqueous solution.
Claim 2
Dependent Claim
68 words
In the process for dyeing textile materials, yarns, threads or fibers dyeable with reactive dyestuffs by contact and treatment with reactive dyestuff, the improvement comprises improving the fastness of the dyed substrate by aftertreating the dyed substrate with 0.5 to 5% by weight of substrate of an aftertreatment agent which is the reaction product of polyethyleneimine and an alkylating agent having two alkylating groups in an aqueous solution.
Claim 3
Dependent Claim
24 words
The process according to claim 1 wherein the dyed substrate is aftertreated with 1 to 3% by weight of substrate of said aftertreatment agent.
Claim 4
Dependent Claim
143 words
The process according to claim 1 wherein the aftertreatment agent is the reaction product of polyethyleneimine of the formula H--CH.sub.2 CH.sub.2 NH).sub.a --CH.sub.2 CH.sub.2 NX).sub.b H with an alkylating agent of the formula Y--CH.sub.2 --Z--CH.sub.2 --Y wherein X is ##STR14## a and b independently are each a number from 0 to 600 and the sum of a and b is 50 to 600; c is a number from 0 to 50; Z is a direct bond, --C n H 2n --, or --C m H 2m --D--C m H 2m --, wherein n is a number from 1 to 4, m is either 1 or 2 and D is --O--, --S--, --NH--, --CO--, --SO--, --SO 2 -- or phenylene; and Y is a substituent which can be eliminated as an anion and comprises chloro, bromo, iodo, hydroxyl, sulphato, sulphonyloxy, phenylsulphonyloxy, tolylsulphonyloxy or ##STR15##

Claim 8
Dependent Claim
29 words
The process according to claim 6 wherein the aftertreatment agent is the reaction product of polyethyleneimine with a bifunctional alkylating agent in a weight ratio of 100:0.1 to 100:1.
Claim 9
Dependent Claim
16 words
The process according to claim 1 wherein the aftertreatment temperature is about 40°° to 100° C.
