Definitions
- the subject of the present invention is a composition comprising an anionic polysaccharide for the care of articles made of textile fibers ("textile care"), based on cotton in particular, colored in particular.
- Care for textile fiber articles, linen in particular, means the protection of the latter against physical or chemical degradation phenomena, in particular the protection of the colors of the colored articles, and / or the contribution to those -these benefits such as softening and / or anti-creasing properties.
- Machine washing of the linen leads to physical and chemical degradation of the fibers and especially of the cotton fibers.
- the alkalinity delivered by detergents as well as certain specific compounds such as oxidizing substances (perborate, percarbonate) or certain enzymes can be at the origin of the chemical degradation of cotton fibers. But it is generally the conjunction of chemical and mechanical actions that leads to fiber degradation.
- the mechanical action is produced during washing, rinsing, spinning or drying, when the latter takes place in a dryer.
- This degradation of the fibers leads to the formation of fibrils on the surface of the textile which ultimately give a loss of luster in colored textiles. This degradation also induces a reduction in the resistance of the textile which in the extreme can lead to a tearing of the fabrics.
- This degradation of the textiles can be quantitatively evaluated either by a loss of the colors of the colored textiles or by a reduction in the breaking energy of the textile. It is generally necessary to carry out 10 to 20 cumulative machine washes to perceive this type of degradation. Cleaning in a washing machine machine which systematically includes a spinning operation also leads to a crumpled cloth which is accentuated during drying, in particular by the formation of inter-fiber hydrogen bonds. An ironing operation is therefore necessary to obtain a presentable appearance of the laundry. In order to reduce the degradation of the fibers during washing or rinsing, the suppliers of chemical products or detergents have resorted to modifications of detergent formulas or to the use of certain specific additives.
- compositions for the treatment of articles of textile fibers in particular based on cotton, colored in particular, of certain anionic polysaccharides of high molecular mass which are soluble under the conditions of use ("working conditions” ) in an aqueous or moist medium of said compositions, made it possible to avoid the degradation of these articles, made it possible to protect the colors and / or provided them with anti-crease and / or softening properties.
- Such compositions may in particular be compositions for washing and / or rinsing and / or softening the laundry, for detaching the laundry before washing ("prespotting"), for drying wet laundry in a dryer or for ironing clothes.

- the molar mass by weight of said anionic polysaccharides can range up to 2,000,000.
- the molar mass by weight Mw of said anionic polysaccharides can be measured by size exclusion chromatography. The measurement is carried out in water at pH 9-10 containing 0.1 M of LiCI and 2/10000 of N 3 Na.
- the molar mass by weight Mw is established in a known manner directly via the light scattering values.
- the degree of substitution or modification DSi corresponds to the average number of hydroxyl functions of the anhydrohexose and / or anhydropentose units substituted or modified by said anionic or anionizable group (s), per anhydrohexose and / or anhydropentose unit.
- Said ionic or ionizable groups are linked to the carbon atoms of the sugar skeleton either directly or via -O- bonds.
- said anionic polysaccharide can also have at least one nonionic group.
- Said nonionic groups are linked to the carbon atoms of the sugar skeleton either directly or via -O- bonds.
- the presence of such groups is expressed in number of moles of substitution MS, that is to say in average number of moles of precursor of said nonionic substituent having reacted by anhydrohexose and / or anhydropentose unit. If said precursor is not capable of forming new reactive hydroxyl groups (alkylation precursor for example), the degree of substitution or modification by all of the anionic or anionizable and nonionic groups is less than 3 by definition .
- the number of moles of substitution MS is theoretically not limited; it can for example go up to 6, preferably up to 2.
- anionic or anionizable groups mention may be made of those containing one or more carboxylate, sulfonate, sulfate, phosphate, phosphonate functions, etc.
