US 8,475,539 B2 · Additive composition for textile auxiliaries

Abstract

The present disclosure relates to compositions for preparing textile auxiliaries, which are used in particular to enhance the dyeing affinity of textile fibers. The disclosure concerns a composition in the form of an aqueous emulsion or solution which comprises (a) one or more hydroxyalkylamines of formula: NX1X2(CnH2nOH), where X1 and X2 are, independently of one other, either hydrogen or hydroxyalkyl radicals of respective formulae Cn1H2n1OH and Cn2H2n2OH, and n, n1 and n2 are integers from 2 to 6, and (b) one or more anionic surfactants selected from alkyl sulphates, alkylsulphonates such as paraffinsulphonates, alkylarylsulphonates, alkyl ether phosphates, and alkyl carboxylates, and at least one compound (c) and/or (d), where (c) is selected from one or more thioureas (thiocarbamides) of formula R1R2N(CS)NR3R4, where R1, R2, R3 and R4 are independently either hydrogen or hydrocarbon radicals having 1 to 5 carbon atoms, and (d) is selected from one or more dialkyl sulphosuccinates in combination with one or more anti-freeze agents selected from methanol, isopropanol, glycols, preferably glycerol, ethylene glycol, propylene glycol or glycol ethers, preferably ethers of ethylene glycol or of propylene glycol.

A textile auxiliary composition consisting of:

a. one or more hydroxyalkylamines of formula:
NX1X2(CnH2nOH) where X1 and X2 each independently are either hydrogen or hydroxyalkyl radicals of respective formulas Cn1H2n1OH and Cn2H2n2OH, and n, n1, n2, are integers ranging from 2 to 6 and
b. one or more anionic surfactants chosen from among alkyl sulphates, alkyl sulphonates, alkylaryl sulphonates, alkylether phosphates, alkyl carboxylates, and at least one compound (c) and/or (d) such that:
c. is chosen from among one or more thioureas (thiocarbamides) of formula R1R2N(CS)NR3R4 where R1, R2, R3, R4 each independently are either hydrogen or hydrocarbon radicals having 1 to 5 carbon atoms, one or more sequestering agents, and mixtures thereof,
d. is chosen from among one or more dialkyl sulphosuccinates or the salts of alkali and alkaline earth metals thereof in combination with one or more anti-freeze agents chosen from among methanol, isopropanol, glycols, or glycol ethers and
wherein (a) represents 1 to 15 weight %, (b) represents 20 to 40 weight %, at least one of:
(c) and (d) represent 3 to 15 weight % of the composition, and
wherein the composition is diluted in water and the total quantity by weight of active matter represented by compounds (a), (b), (c) and/or (d) ranges from 0.2% to 25%.
