## Abstract

A fiber treatment chemical includes a lactic ester derivative represented by the following formula (1): ##STR1## wherein RCO means a fatty acid having 12-32 carbon atoms, n stands for a number of 1-4, and X denotes hydrogen, a monovalent or divalent metal, ammonium, or amine. A fiber treatment composition comprising this fiber treatment chemical, and fiber and textile goods are treated with the fiber treatment chemical or fiber treatment composition.

## Claims

### Claim 1

A fiber treatment chemical comprising a lactic ester derivative for providing softness to textile goods represented by the following formula (1), said fiber treatment chemical being excellent in antistatic property-imparting effect: ##STR3## wherein RCO means a fatty acid having 12-32 carbon atoms, n stands for a number of 1-4, and X is selected from the group consisting of monovalent metals and a monoethanolamine.

### Claim 2 (depends on 1)

The fiber treatment chemical according to claim 1, wherein the fiber treatment chemical provides antistatic ability to the textile goods.

### Claim 3

A fiber treatment composition comprising a fiber treatment chemical in a proportion of at least 40 wt % in the composition other than water, said fiber treatment chemical comprising a lactic ester derivative for providing softness to textile products represented by the following formula (1), said fiber treatment chemical being excellent in antistatic property-imparting effect: ##STR4## wherein RCO means a fatty acid having 12-32 carbon atoms, n stands for a number of 1-4, and X is selected from the group consisting of monovalent metals and a monoethanolamine.

### Claim 4 (depends on 3)

The fiber treatment composition according to claim 3, further comprising a dispersion stabilizer.

### Claim 5

Textile goods for use in direct contact with skin of a user comprising the textile goods treated with a fiber treatment chemical comprising a lactic ester derivative for providing softness to textile products represented by the following formula (1), said fiber treatment chemical being excellent in antistatic property-imparting effect: ##STR5## wherein RCO means a fatty acid having 12-32 carbon atoms, n stands for a number of 1-4, and X is selected from the group consisting of monovalent metals and a monoethanolamine.

### Claim 6

A method of using a lactic ester derivative for providing softness to textile goods directly contacting skin of a user comprising, treating the textile goods or fibers for forming the textile goods with a fiber treatment chemical comprising a lactic ester derivative for providing softness to textile products represented by the following formula (1): ##STR6## wherein RCO means a fatty acid having 12-32 carbon atoms, n stands for a number of 1-4, and X denotes hydrogen, a monovalent or divalent metal, ammonium, or amine.

### Claim 7 (depends on 6)

The method according to claim 6, wherein X in the formula (1) is selected from the group consisting of diethanolamine, triethanolamine and propanolamine, and the fiber treatment chemical is excellent in softness and smoothness-imparting effect.

### Claim 8 (depends on 6)

The method according to claim 6, wherein X in the formula (1) is selected from the group consisting of monovalent metals and a monoethanolamine, and the fiber treatment chemical is excellent in antistatic property-imparting effect.

### Claim 9 (depends on 6)

The method according to claim 6, wherein X in the formula (1) is selected from the group consisting of potassium, sodium and calcium, and the fiber treatment chemical has low toxicity.

### Claim 10 (depends on 6)

The method according to claim 6, wherein the fiber treatment chemical is adhered to the fibers in an amount of 0.1-1.0 wt %.

### Claim 11 (depends on 6)

The method according to claim 6, wherein the fiber treatment chemical provides antistatic ability to the textile goods.
