Abstract

The present invention relates to an alkoxylated polyethylenimine, for use in textile treatment in textile industry, especially in textile finishing processes.

First claim

1 . A process for treating a textile in a textile finishing process comprising contacting the textile with an alkoxylated polyethylenimine having alkylene oxide segments attached to the nitrogen atoms of the polyethylenimine,
wherein the alkylene oxide segments comprise an ethylene oxide segment and C3-C4-alkylene oxide segment; wherein a molar ratio of the ethylene oxide segment to the remaining alkylene oxide segment is in a range of 1:2 to 3:1, wherein the amount of alkylene oxide segments is on average in the range of from 35 to 70 alkylene oxide segments per nitrogen atom, wherein a weight average molecular weight (Mw) of the alkoxylated polyethylenimine is in a range of 30,000 to 50,000 g/mol.

2 . The process according to claim 1 , wherein the alkoxylated polyethyleneimine is used in combination with a hydrophobic textile softener in a textile softening composition or is used in combination with a water-repellant agent in a water-repellant composition.

3 . The process according to claim 2 , wherein the hydrophobic textile softener is selected from the group consisting an amino modified silicone oil, wax, ester, long carbon chain alcohol, and quaternary ammonium compound or wherein the water repellant agent is selected from the group consisting of a fluoro-containing water-repellant agent or a silicon-containing water-repellant agent.

4 . The process according to claim 2 , wherein an amount of the alkoxylated polyethyleneimine in the textile softening composition is in a range of from 1 to 50% by weight, based on the total weight of the alkoxylated polyethyleneimine and hydrophobic textile softener; or wherein the amount of the alkoxylated polyethyleneimine in the water-repellant composition is in a range of 0.1 to 6% by weight, based on the total weight of the alkoxylated polyethyleneimine and water-repellant agent.

5 . The process according to claim 1 , wherein the alkylene oxide segments comprises an ethylene oxide segment and a C 3 -alkylene oxide segment.

6 . The process according to claim 1 , wherein the molar ratio of ethylene oxide to the remaining alkylene oxide segment in a range of 1:1 to 2:1.

7 . The process according to claim 1 , wherein the molar ratio of ethylene oxide to the remaining alkylene oxide segment in a range of 1:1 to 3:2.

8 . The process according to claim 1 , wherein the amount of alkylene oxide segments is on the average in the range of from 35 to 60 alkylene oxide segments per nitrogen atoms.

9 . A process for treating a textile in a textile finishing process comprising contacting the textile with an alkoxylated polyethylenimine having alkylene oxide segments attached to the nitrogen atoms of the polyethylenimine,
wherein the alkylene oxide segments comprise an ethylene oxide segment and C3-C4-alkylene oxide segment; wherein a molar ratio of the ethylene oxide segment to the remaining alkylene oxide segment is in a range of 1:2 to 3:1, wherein the amount of alkylene oxide segments is on average in the range of from 35 to 55 alkylene oxide segments per nitrogen atom, wherein a weight average molecular weight (Mw) of the alkoxylated polyethylenimine is in a range of 30,000 to 50,000 g/mol.

10 . The process according to claim 1 wherein the weight average molecular weight (Mw) of the alkoxylated polyethylinime is in the range of 35,000 to 40,000 g/mol.

11 . The process according to claim 4 , wherein the amount of the alkoxylated polyethylamine in the textile softening composition is in the range of 1 to 25% by weight.

12 . The process according to claim 4 , wherein the amount of the alkoxylated polyethylamine in the textile softening composition is in the range of 1 to 20% by weight.

13 . The process according to claim 4 , wherein the amount of the alkoxylated polyethylamine in the textile softening composition is in the range of 1 to 10% by weight.

14 . The process according to claim 4 , wherein the amount of the alkoxylated polyethylamine in the water repellant composition is in the range of 0.1 to 4% by weight.

15 . The process according to claim 4 , wherein the amount of the alkoxylated polyethylamine in the water repellant composition is in the range of 0.1 to 2% by weight.

16 . The process according to claim 4 , wherein the amount of the alkoxylated polyethylamine in the water repellant composition is in the range of 0.1 to 1% by weight.
