Disclosed is an elastic fiber treatment agent that contains a polyether-modified silicone, a smoothing agent other than the polyether-modified silicone, and water. The polyether-modified silicone is contained in the elastic fiber treatment agent at a content of 0.01% by mass or more and 10% by mass or less. The polyether-modified silicone has a hydrophilic-lipophilic balance (HLB) of 1 or more and 7 or less.

Treatment agent for elastic fibers, and elastic fibers

Disclosed is an elastic fiber treatment agent that contains a silicone oil as a smoothing agent (A), an unsaturated fatty acid metal salt (B), and a higher alcohol (D), and optionally an organic phosphate ester compound (C). An alcohol forming the higher alcohol (D) is a Guerbet alcohol.

Disclosed is an elastic fiber treatment agent that contains a smoothing agent and an alkyl phosphate ester compound. The alkyl phosphate ester compound contains specific phosphate ester Q1 and at least one or more selected from specific phosphate esters Q2 and Q3. In a P nucleus NMR measurement of the alkyl phosphate ester compound upon an alkali over-neutralization pretreatment, a P nucleus NMR integral ratio attributed to the phosphate ester Q1 is 15% to 60% if the sum of P nucleus NMR integral ratios attributed to the phosphate esters Q1 to Q3 and phosphoric acid and its salt is taken as 100%.

Treatment agent for elastic fibers, and elastic fiber

An elastic fiber treatment agent that contains, as a smoothing agent, a mineral oil with a content ratio of an aromatic component of less than 1% by mass and an aniline point of 70° C. to 110° C. The mineral oil has a mass ratio between the content of a naphthene component and the content of a paraffin component of such that naphthene component/paraffin component=30 to 50/70 to 50.

Please replace the Abstract of the Disclosure with the following: An elastic fiber treatment agent that contains a smoothing agent, water and an organic phosphoric acid ester salt. The smoothing agent contains a mineral oil with an aniline point of not more than 110&#xb0; C., a silicone oil, and optionally an ester oil. Assuming that the sum of the content ratios of the smoothing agent, the water, and the organic phosphoric acid ester salt in the elastic fiber treatment agent is 100 parts by mass, the elastic fiber treatment agent contains the mineral oil at a ratio of 20 to 90 parts by mass and the water at a ratio of 0.01 to 2 parts by mass.
