COMPOSITION A BASE DE NANOPARTICULES OU DE NANOLATEX DE POLYMERES POUR LE TRAITEMENT DU LINGE COMPOSITION BASED ON NANOPARTICLES OR NANOLATEX OF POLYMERS FOR THE TREATMENT OF LAUNDRY
La présente invention a pour objet l'utilisation, dans une composition pour le traitement du linge à base de coton notamment, de nanoparticules de polymère ou d'un nanolatex de polymère non soluble dans les conditions d'utilisation directe et/ou indirecte en milieu aqueux ou humide de ladite composition, comme agent d'antifroissage ou d'aide au repassage dudit linge. II est connu (FR-A-1.416.813) de prétraiter (par foulardage, pulvérisation ou application à la brosse) avant usage les fibres ou articles fibreux textiles (tapis, étoffes) à l'aide d'une composition comprenant un latex de polystyrène ou de copolymère de styrène avec un ester (meth)acrylique ou acide (meth)acrylique comprenant une bétaïne comme agent émulsionnant ; ce prétraitement a pour but d'empêcher ou de réduire la salissure des articles et d'apporter un fini délustrant mat.The subject of the present invention is the use, in a composition for the treatment of linen based on cotton in particular, of polymer nanoparticles or of a polymer nanolatex which is not soluble under the conditions of direct and / or indirect use in medium aqueous or wet of said composition, as an anti-crease or ironing aid for said laundry. It is known (FR-A-1,416,813) to pretreat (by padding, spraying or brushing) before use the fibers or textile fibrous articles (carpets, fabrics) using a composition comprising a latex of polystyrene or styrene copolymer with a (meth) acrylic ester or (meth) acrylic acid comprising a betaine as an emulsifying agent; the purpose of this pretreatment is to prevent or reduce the soiling of the articles and to provide a matt finish.
Il a également été proposé (US-A-4,746,455) d'utiliser dans les compositions détergentes liquides des latex de polymères non-ioniques ou de copolymères dérivés de monomères non-ioniques et éventuellement de monomères cationiques et/ou anioniques, comme agent d'antifeutrage.It has also been proposed (US-A-4,746,455) to use in liquid detergent compositions latexes of nonionic polymers or of copolymers derived from nonionic monomers and optionally from cationic and / or anionic monomers, as antifeutrage.

Le nettoyage en machine lave linge comporte une opération d'essorage qui conduit à un linge froissé qui est accentué lors du séchage, notamment par la formation de liaisons hydrogènes inter-fibres. Une opération de repassage est donc nécessaire pour obtenir un aspect présentable du linge.Cleaning in a washing machine machine involves a spinning operation which results in 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.
La demanderesse a trouvé que l'utilisation, dans des compositions pour le traitement du linge notammment à base de coton, de nanoparticules ou de nanolatex de polymères non solubles apportait à celui-ci des propriétés d'antifroissage ou facilitait le repassage de celui-ci.The Applicant has found that the use, in compositions for the treatment of linen, in particular cotton-based, of nanoparticles or nanolatex of insoluble polymers brings to the latter anti-creasing properties or facilitates the ironing thereof. .

Formulation détergenteDetergent formulation
On réalise une opération de lavage dans un appareil de laboratoire Tergotomètre bien connu dans la profession des formulateurs de compositions détergentes. L'appareil simule les effets mécaniques et thermiques des machines à laver de type américain à pulsateur, mais grâce à la présence de 6 pots de lavage, il permet de réaliser des séries d'essais simultanés avec une économie de temps appréciable. On découpe des éprouvettes de coton désapprêté de dimensions 25X25 cm. Les éprouvettes de coton sont d'abord repassées afin d'avoir toutes le même niveau de froissage avant lavage.A washing operation is carried out in a laboratory apparatus Tergotometer well known in the profession of formulators of detergent compositions. The device simulates the mechanical and thermal effects of washing machines of the American type with pulsator, but thanks to the presence of 6 washing pots, it allows to carry out series of simultaneous tests with an appreciable saving of time. We cut out of cotton samples 25x25 cm. The cotton test pieces are first ironed in order to all have the same level of crumpling before washing.
Elles sont ensuite lavées à l'aide de la formulation détergente ci-dessus contenant le latex (I) et rincées 1 fois, dans les conditions suivantes :They are then washed using the above detergent formulation containing the latex (I) and rinsed 1 time, under the following conditions:
- nombre d'éprouvettes par pot du Tergotomètre : 2- number of test tubes per jar of the Tergotometer: 2
- volume d'eau : 1 litre- water volume: 1 liter
- eau de dureté française 30°TH obtenue par dilution appropriée d'eau minérale de marque Contrexéville® - concentration en lessive : 5 g/l- water with French hardness 30 ° TH obtained by appropriate dilution of Contrexéville® brand mineral water - detergent concentration: 5 g / l
- température de lavage : 40°C- washing temperature: 40 ° C
- durée du lavage : 20 min- washing time: 20 min
- vitesse d'agitation du Tergotomètre : 100 RPM- Tergotometer stirring speed: 100 RPM
- rinçage à l'eau froide (environ 30°TH) - durée de rinçage : 5 minutes- rinse with cold water (around 30 ° TH) - rinse time: 5 minutes
Les éprouvettes sont ensuites froissées sous une presse de 3kg pendant 20 secondes, puis mises à sécher verticalement pendant une nuit.The test pieces are then crumpled under a 3 kg press for 20 seconds, then allowed to dry vertically overnight.
La même opération est réalisée à l'aide de la même formulation détergente mais exempte de latex (I). On réalise ensuite une photographie numérique en couleur des éprouvettes sèches, qui est ensuite transformée en 256 niveaux de gris (échelle de gris de 0 à 255).The same operation is carried out using the same detergent formulation but free of latex (I). A digital color photograph of the dry specimens is then produced, which is then transformed into 256 levels of gray (gray scale from 0 to 255).
On compte le nombre de pixels correspondant à chaque niveau de gris.We count the number of pixels corresponding to each gray level.
Pour chaque histogramme obtenu, on mesure l'écart type σ de la distribution du niveau de gris. σi correspond à l'écart type obtenu avec la formulation détergente ne renfermant pas de latex. σ2 correspond à l'écart type obtenu avec la formulation détergente renfermant le latex (I). La valeur de performance est donnée par l'équation -Δσ = σ2-σlFor each histogram obtained, the standard deviation σ of the distribution of the gray level is measured. σi corresponds to the standard deviation obtained with the detergent formulation not containing latex. σ2 corresponds to the standard deviation obtained with the detergent formulation containing the latex (I). The performance value is given by the equation -Δσ = σ2-σl
Les valeurs de performance obtenues sont les suivantes :The performance values obtained are as follows:
Ces valeurs positives de -Δσ sont représentatives d'une propriété d'antifroissage apportée par la formulation détergente comprenant le latex selon l'invention. Exemple 2These positive values of -Δσ are representative of an anti-creasing property provided by the detergent formulation comprising the latex according to the invention. Example 2
