## Abstract

A process of imparting anti-static properties to textile materials, especially carpets, comprises treating the material with an aqueous solution of a quarternary ammonium salt and a water soluble polyether. Quarternary ammonium salts, containing three C.sub.8 -C.sub.10 alkyl or aralkyl groups, normally insoluble in water, are soluble in the polyether; and compositions of quarternary ammonium salt and polyether may be diluted with water and applied to textile material to produce an anti-static finish.

## Claims

### Claim 1

A composition for treating textiles which comprises a quarternary ammonium salt containing a methyl group and three alkyl or aralkyl groups containing from eight to ten carbon atoms, and a water soluble polyether.

### Claim 2 (depends on 1)

A composition as claimed in claim 1 in which the quarternary ammonium salt is tri-caprylyl methyl ammonium chloride.

### Claim 3 (depends on 1)

A composition as claimed in claim 1 in which the polyether is obtained by the condensation of an alkylene oxide with an aromatic, aliphatic or heterocyclic compound containing an active hydrogen atom.

### Claim 4 (depends on 3)

A composition as claimed in claim 3 in which the compound containing an active hydrogen atom is an alkyl phenol, polyol or a fatty acid.

### Claim 5 (depends on 1, 2, 3, 4)

A composition as claimed in any one of claims 1 to 4 in which the polyether is a condensation product of ethylene oxide and nonyl phenol.

### Claim 6 (depends on 1, 2, 3, 4)

A composition as claimed in any one of claims 1 to 4 containing one part by weight of quarternary ammonium salt and from one to five parts by weight of polyether.

### Claim 7 (depends on 1, 2, 3, 4)

A method of imparting anti-static properties to textile materials which comprises treating the material with an aqueous composition as claimed in any one of claims 1 to 4.

### Claim 8 (depends on 7)

A method as claimed in claim 7 in which the composition is diluted with from ten to one hundred parts by weight of water.

### Claim 9 (depends on 7)

A method as claimed in claim 7 in which the composition is used in sufficient amount to deposit from 0.2 to 1 percent by weight of the quarternary ammonium compound onto textiles.

### Claim 10 (depends on 9)

A method as claimed in claim 9 in which the amount is from 0.5 to 0.7 percent by weight.

### Claim 11 (depends on 7)

A method as claimed in claim 7 in which the compositions are applied to textile materials at a temperature of from 20.degree. to 25.degree. C.

### Claim 12 (depends on 7)

A method as claimed in claim 7 in which the textile material is a wool textile material.

### Claim 13 (depends on 7)

A method as claimed in claim 7 in which the textile material is treated after dyeing.
