Abstract

The present invention provides a fiber modifier composed of an internal olefin sulfonate having 17 or more and 24 or less carbons.

First claim

The invention claimed is:

1. A finishing agent composition for textile products, comprising a fiber modifier consisting of an internal olefin sulfonate having 17 or more and 24 or less carbons, and a polyvalent metal salt.

2. The finishing agent composition for textile products according to claim 1 , wherein
a content of 1-olefin sulfonate in the internal olefin sulfonate having 17 or more and 24 or less carbons is 10% by mass or less.

3. The finishing agent composition for textile products according to claim 1 , wherein the polyvalent metal salt is one or more polyvalent metal salts selected from inorganic polyvalent metal salts and organic polyvalent metal salts.

4. The finishing agent composition for textile products according to claim 3 , wherein the inorganic polyvalent metal salts are one or more inorganic polyvalent metal salts selected from inorganic divalent metal salts and inorganic trivalent metal salts, and the organic polyvalent metal salts are one or more organic polyvalent metal salts selected from organic divalent metal salts and organic trivalent metal salts.

5. The finishing agent composition for textile products according to claim 4 , wherein the inorganic divalent metal salts are one or more inorganic divalent metal salts selected from calcium salts and magnesium salts, and the inorganic trivalent metal salts are aluminum salts.

6. The finishing agent composition for textile products according to claim 4 , wherein the organic polyvalent metal salts are organic polyvalent metal salts having 1 or more and 8 or less carbons.

7. The finishing agent composition for textile products according to claim 1 , wherein a content of the polyvalent metal salts in the finishing agent composition for textile products is 10 mg/kg or more and 20% by mass or less.

8. The finishing agent composition for textile products according to claim 1 , wherein
a content of a metal ion chelating agent in the finishing agent composition for textile products is 0% by mass or more and 20% by mass or less.

9. The finishing agent composition for textile products according to claim 8 , wherein the metal ion chelating agent is one or more selected from (C1) metal ion chelates that are inorganic compounds and (C2) metal ion chelating agents that are organic compounds.

10. The finishing agent composition for textile products according to claim 9 , wherein (C1) is one or more metal ion chelates selected from (C1-1) alkali metal silicates, (C1-2) aluminosilicates, and (C1-3) tripolyphosphates.

11. The finishing agent composition for textile products according to claim 9 , wherein (C2) is one or more metal ion chelating agents selected from (C2-1) di- or higher and tetra- or lower valent carboxylic acids or salts thereof free from amino groups and having 4 or more and 12 or less carbons, (C2-2) di- or higher and tetra- or lower valent carboxylic acids or salts thereof containing an amino group and having 4 or more and 10 or less carbons, and (C2-3) compounds having a phosphonate group or a salt thereof in the molecule.

12. A method for finishing textile products, comprising:
contacting the textile products with a treatment liquid for textile products containing water, an internal olefin sulfonate having 17 or more and 24 or less carbons in an amount of 0.002% by mass or more and 6% by mass or less relative to the textile products and a polyvalent metal salt.

13. The method for finishing textile products according to claim 12 , wherein
a content of 1-olefin sulfonate in the internal olefin sulfonate having 17 or more and 24 or less carbons is 10% by mass or less.

14. The method for finishing textile products according to claim 12 , wherein
the internal olefin sulfonate having 17 or more and 24 or less carbons comprises an internal olefin sulfonate having 17 or more and 24 or less carbons with the sulfonate group at position 2 or higher and 4 or lower (IO-1S) and an internal olefin sulfonate having 17 or more and 24 or less carbons with the sulfonate group at position 5 or higher (IO-2S), wherein a mass ratio (IO-1S)/(IO-2S) of (IO-1S) to (IO-25) is 0.6 or more and 6 or less.

15. The method for finishing textile products according to claim 12 , wherein the internal olefin sulfonate having 17 or more and 24 or less carbons contains an internal olefin sulfonic acid having 18 or more carbons in an amount of 80% by mass or more, and an internal olefin sulfonate having 20 or more and 24 or less carbons in an amount of 20% by mass or less.

16. The method for finishing textile products according to claim 12 , wherein a content of 1-olefin sulfonate in the internal olefin sulfonate having 17 or more and 24 or less carbons is 10% by mass or less.

17. A method for finishing textile products, comprising:
contacting the textile products with a treatment liquid for textile products containing water, an internal olefin sulfonate having 17 or more and 24 or less carbons in an amount of 0.002% by mass or more and 6% by mass or less relative to the textile products and a polyvalent metal salt;
wherein the treatment liquid is obtained by mixing the finishing agent composition for textile products according to claim 1 with water.

18. A method for treating textile products, comprising:
step 1 of washing the textile products with a washing liquid containing one or more surfactants selected from anionic surfactants and nonionic surfactants; and
step 2 of contacting the textile products after step 1 with a treatment liquid for textile products containing water, an internal olefin sulfonate having 17 or more and 24 or less carbons in an amount of 0.002% by mass or more and 6% by mass or less relative to the textile products and a polyvalent metal salt.

19. The method for treating textile products according to claim 18 , wherein
