Abstract

A softening agent includes: a component (A) which is a compound represented by formula (1); and a component (B) which is an alcohol with 6 or more carbons. R 1 and R 2 each independently represent a hydrocarbon group with 6 or more and 24 or less carbons, with the proviso that at least one of R 1 and R 2 is a hydrocarbon group having a branch chain; A 1 O and A 2 O each independently represent an alkyleneoxy group with 2 or more and 4 or less carbons; x1 and x2 each independently represent an average number of added moles, which is a number of 0 or more and 10 or less; and M is a cation.

First claim

The invention claimed is:

1. A softening agent comprising:
a component (A) which is sodium di(2-propylheptyl) sulfosuccinate; and
a component (B) which is at least one alcohol selected from the 1-heptanol, 1-octanol, 1-nonanol, 1-decanol, 1-undecanol, 1-dodecanol, 1-tridecanol, and 1-tetradecanol,
wherein a proportion of the component (A) relative to a total of 100 parts by mass of the components (A) and (B) is 50 parts by mass to 90 parts by mass, and a proportion of the component (B) relative to the total of 100 parts by mass of the components (A) and (B) is 10 parts by mass to 50 parts by mass.

2. A treatment liquid comprising:
the softening agent according to claim 1 ; and
water comprising a hardness component.

3. The softening agent according to claim 1 , wherein a proportion of the component (B) relative to a total of 100 parts by mass of the components (A) and (B) is 20 parts by mass to 40 parts by mass.

4. The softening agent according to claim 1 , wherein a proportion of the component (B) relative to a total of 100 parts by mass of the components (A) and (B) is 20 parts by mass to 30 parts by mass.

5. A method for treating fibers comprising bringing a treatment liquid into contact with the fibers, the treatment liquid comprising a softening agent and water, the softening agent comprising:
a component (A) which is sodium di(2-propylheptyl) sulfosuccinate; and
a component (B) which is at least one alcohol selected from the 1-heptanol, 1-octanol, 1-nonanol, 1-decanol, 1-undecanol, 1-dodecanol, 1-tridecanol, and 1-tetradecanol,
wherein a proportion of the component (A) relative to a total of 100 parts by mass of the components (A) and (B) is 50 parts by mass to 90 parts by mass, and a proportion of the component (B) relative to the total of 100 parts by mass of the components (A) and (B) is 10 parts by mass to 50 parts by mass

wherein R 1 and R 2 each independently represent a hydrocarbon group with 6 or more and 24 or less carbons, with the proviso that at least one of R 1 and R 2 is a hydrocarbon group having a branch chain, A 1 O and A 2 O each independently represent an alkyleneoxy group with 2 or more and 4 or less carbons, x1 and x2 each independently represent an average number of added moles, which is a number of 0 or more and 10 or less, and M is a cation.

6. The method for treating fibers according to claim 5 , wherein the water comprises a hardness component.

7. The method for treating fibers according to claim 5 , wherein the treatment liquid is brought into contact with a textile product.

8. The method for treating fibers according to claim 7 , wherein the textile product is a textile.

9. The method for treating fibers according to claim 7 , wherein the textile product is cloth.

10. The method for treating fibers according to claim 5 , wherein an amount of a total of the components (A) and (B) in the treatment liquid is from 0.01% o.w.f. or more to 5% o.w.f. or less relative to a weight of the fibers.
