Abstract

Use for sizing textile materials with an aqueous sizing composition including at least one co-polymer obtained by the polymerization of at least one non-ionic monomer and/or one anionic monomer, and at least one monomer of formula (I):

in which:
R 1 is an atom of hydrogen or a methyl radical; x=0 or 1; Z is a divalent grouping —C(═O)—O—, —C(═O)—NH—, or —CH 2 —; n is an integer between 1 and 250; R 2 is a hydrogen atom or a carbonated radical—saturated or unsaturated, possibly aromatic, linear, ramified or cyclic—including from 1 to 30 carbon atoms and from 0 to 4 hetero-atoms chosen from the group including O, N and S.

First claim

The invention claimed is:

1. A process for manufacturing a textile, the process comprising the following stages:
preparing an aqueous sizing composition including at least one co-polymer obtained by the polymerization of at least one non-ionic monomer and/or one anionic monomer, and at least one monomer of formula (I),

in which:
R 1 is hydrogen or a methyl group;
x =0 or 1;
Z is a divalent grouping —C(═O)—O—, —C(═O)—NH—, or —CH 2 —;
n is an integer between 1 and 250; and
R 2 is hydrogen, C 1 -C 30 alkyl, or phenyl,
wherein the non-ionic monomer is selected from the group consisting of acrylamide, methacrylamide, N-i sopropylacrylamide, N,N-dimethylacrylamide, N-methylolacrylamide, N-vinylformamide, N-vinyl acetamide, N-vinylpyridine, N-vinylpyrrolidone, acryloyl morpholine (ACMO), and acrylamide diacetone, and
wherein the anionic monomer is selected from the group consisting of acrylic acid, methacrylic acid, and 2-acrylamido-2-methylpropane sulfonic acid, and their salts;

optionally, heating the said composition;
sizing a textile material with the aqueous sizing composition, thereby obtaining sized textile material;
weaving the sized textile material; and
desizing the textile material at the end of the weaving stage, wherein said desizing comprises removing—by means of an aqueous solution—sizing composition previously deposited on a surface of the textile material.

2. A process according to claim 1 , further comprising, after the sizing and weaving stages, a drying stage.

3. A process according to claim 1 , wherein the textile material is a yarn, filament, textile fiber, or weaved or unweaved fabric; and the said textile material is natural and/or artificial.

4. A process according to claim 1 , wherein the co-polymer is obtained by the polymerization of monomers consisting of:
one or more non-ionic monomers selected from the group consisting of acrylamide, methacrylamide, N-isopropylacrylamide, N,N-dimethylacrylamide, N-methylolacryl amide, N-vinylformamide, N-vinyl acetamide, N-vinylpyridine, N-vinylpyrrolidone, acryloyl morpholine (ACMO), and acrylamide diacetone;
one or more anionic monomers selected from the group consisting of acrylic acid, methacrylic acid, and 2-acrylamido-2-methylpropane sulfonic acid, and their salts; and
one or more monomers of formula (I).

5. A process according to claim 1 , wherein the co-polymer is obtained by polymerizing a monomer mixture, wherein all non-ionic monomers in the mixture are selected from compounds of formula (I) and the non-ionic monomers listed in claim 1 , and wherein all anionic monomers in the mixture are selected from the anionic monomers listed in claim 1 .

6. A process according to claim 1 , wherein the formula (I) monomer represents between 0.5 and 50% in weight, in relation to the total weight of the co-polymer.

7. A process according to claim 1 , wherein the formula (I) monomer is selected from the group consisting of poly(ethylene-glycol) (meth)acrylates and methyl-poly(ethylene-glycol) (meth)acrylates.

8. A process according to claim 1 , wherein the co-polymer includes, in weight in relation to the total weight of the co-polymer:
from 10 to 99.5% of at least one non-ionic monomer;
from 0 to 80% of at least one anionic monomer; and
from 0.5 to 50% of formula (I) monomer.

9. A process according to claim 8 , wherein the co-polymer consists of, in weight in relation to the total weight of the co-polymer:
from 10 to 99.5% of at least one non-ionic monomer selected from the group consisting of acrylamide, methacrylamide, N-isopropylacrylamide, N,N-dimethylacrylamide, N-methylolacrylamide, N-vinylformamide, N-vinyl acetamide, N-vinylpyridine, N-vinylpyrrolidone, acryloyl morpholine (ACMO), and acrylamide diacetone;
from 0 to 80% of at least one anionic monomer selected from the group consisting of acrylic acid, methacrylic acid, and 2-acrylamido-2-methylpropane sulfonic acid, and their salts; and
from 0.5 to 50% of at least one monomer of formula (I).

10. A process according to claim 1 , wherein the co-polymer includes, in weight in relation to the total weight of the co-polymer:
from 40 to 99% of acrylamide;
from 0 to 40% of acrylic acid in acid and/or its salt; and
from 1 to 25% of formula (I) monomer.

11. A process according to claim 1 , wherein the co-polymer is obtained by polymerization in solution or in bulk.

12. A process according to claim 1 , wherein the composition contains between 0.1 and 10% in weight of co-polymer.
