Abstract
Abstract This invention relates to compositions comprising a class of new chemical compounds which can be applied to a textile material preferably composed of fibers of cellulose, regenerated cellulose or a cellulose ester or ether, to contribute an attractive softening effect. The new compounds possess a hydrophilic solubilising group linked to each of two triazine rings and an average of two hydrophobic groups and two halogen substituents per molecule. After impregnation with the compositions of the invention the compounds are fixed to the textile material by heating at 100°-150°C.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
168 words
A process for conditioning a textile material composed of fibres selected from the group consisting of cellulose, regenerated cellulose, cellulose ester and cellulose ether fibres comprising a impregnating the textile material with an aqueous composition comprising a compound of the general formula ##EQU5## in which A represents an ethenoxy; propenoxy; 1,2 or 2,3 butenoxy group or a combination thereof, VWYZ represent halogen, -OH, -NRR 1 or -OR 1 providing that at least one of VW and at least one of YZ is halogen and at least one of VWYZ is -OR 1 or-NRR 1 , R represents hydrogen or a C 12 -C 30 linear or branched chain alkyl group, R 1 represents a C 12 -C 30 linear or branched chain alkyl group, n=1-80 b treating the impregnated material with an aqueous solution containing an acid binding agent and having a pH of at least 7.5; c heating the treated textile material at a temperature of 100° to 150°C for a time effective to fix the compound.
Claim 2
Dependent Claim
168 words
A process for conditioning a textile material composed of fibres selected from the group consisting of cellulose, regenerated cellulose, cellulose ester and cellulose ether fibres comprising a impregnating the textile material with an aqueous composition comprising a compound of the general formula ##EQU5## in which A represents an ethenoxy; propenoxy; 1,2 or 2,3 butenoxy group or a combination thereof, VWYZ represent halogen, -OH, -NRR 1 or -OR 1 providing that at least one of VW and at least one of YZ is halogen and at least one of VWYZ is -OR 1 or-NRR 1 , R represents hydrogen or a C 12 -C 30 linear or branched chain alkyl group, R 1 represents a C 12 -C 30 linear or branched chain alkyl group, n=1-80 b treating the impregnated material with an aqueous solution containing an acid binding agent and having a pH of at least 7.5; c heating the treated textile material at a temperature of 100° to 150°C for a time effective to fix the compound.
Claim 3
Dependent Claim
15 words
A process as claimed in claim 1 the aqueous composition additionally contains a chlorinated hydrocarbon.
Claim 4
Dependent Claim
59 words
A process for conditioning a textile material as claimed in claim 1, in which the textile material is impregnated with an aqueous composition containing the compound as defined in claim 1 and an acid binding agent and the impregnated textile material is subsequently heated at a temperature of 100° to 150°C for a time effective to fix the compound.
Claim 5
Dependent Claim
17 words
A process as claimed in claim 3 in which the aqueous composition additionally contains a chlorinated hydrocarbon.
