Abstract

Textile size compositions which are dispersible in water and comprise an alkali metal and/or ammonium salt of a styrene-maleic anhydride copolymer, containing as a copolymerized component a diester of an olefinically unsaturated dicarboxylic acid or anhydride and a monohydric alcohol and/or a polyester of such an acid or anhydride and a polyhydric alcohol. Also, textile size compositions which are dispersible in water and comprise a mixed salt of a styrene-maleic anhydride copolymer, wherein 20 to 80 weight percent of the cations of said salt are ammonium cations and 20 to 80 weight percent of the cations of said salt are alkali metal cations. Methods for sizing yarns and yarn sized with the above-mentioned compositions.

Claims

1. A textile size composition dispersible in water comprising a mixed salt of a styrene-maleic anhydride copolymer, 20 to 80 weight percent of the cations of said salt being ammonium cations and 20 to 80 weight percent of said cations being alkali metal cations.

2. A composition for treating textile materials which comprises an aqueous solution of a mixed salt of an interpolymer wherein said interpolymer comprises

a. 1.0 molar proportion of at least one carboxylic monomer selected from the group consisting of maleic anhydride,

b. from 0.1 to 1.5 molar proportion of at least one monovinyl aromatic monomer containing from 8 to 12 carbon atoms, and

the total of monomer (b) being at least 1.0 molar proportion;

and wherein

a'"'"'. from 20 to 80% of the free carboxyl groups of said interpolymer are combined with at least one fixed base selected from the group consisting of alkali metal bases, and

b'"'"'. from 20 to 80% of the free carboxyl groups of said interpolymer are combined with at least one fugitive base selected from the group consisting of ammonia, ammonium hydroxide and volatile amines,

such that a total of from 40 to 100% of said free carboxyl groups are so combined.

3. The composition as in claim 2 wherein the carboxylic monomer is maleic anhydride and the monovinyl aromatic monomer is styrene.

4. The composition as in claim 2 wherein the fixed base is sodium hydroxide and the fugitive base is ammonia or ammonium hydroxide.

7. A textile material treated with the composition of claim 2.

5. A composition for treating textile materials which comprises an aqueous solution of a mixed salt of an interpolymer comprising 1.0 molar proportion of maleic anhydride and from 1.0 to 1.5 molar proportion of styrene, and wherein

a'"'"'. from 20 to 80% of the free carboxyl groups of said interpolymer are combined with at least one fixed cation derived from the group consisting of alkali metal bases, and

b'"'"'. from 20 to 80% of the free carboxyl groups of said interpolymer are combined with at least one fugitive cation derived from the group consisting of ammonia,

ammonium hydroxide and volatile amines, such that a total of from 40 to 100% of said free carboxyl groups are so combined.

6. The composition as in claim 5 wherein the fixed base is sodium hydroxide and the fugitive base is ammonia or ammonium hydroxide.

8. A textile material treated with the composition of claim 5.
