Description
Composition hydrophobe et procédé de fabrication de motifs hydrofuges sur un tissu au moyen de ladite composition.Hydrophobic composition and method of manufacturing water repellent patterns on a fabric using said composition.
La présente invention concerne une composition hydrophobe et un procédé de fabrication de motifs hydrofuges sur un tissu au moyen de ladite composition. The present invention relates to a hydrophobic composition and to a process for manufacturing water-repellent patterns on a fabric using said composition.
D'une manière générale, lorsqu'un tissu, qui n'est pas essentiellement constitué de fibres synthétiques imperméables, est mis au contact de l'eau, il reste imprégné et prend une couleur plus sombre. Il existe par ailleurs des agents imperméabilisants pour le traitement superficiel des tissus mais ces produits ont une efficacité très réduite dans le temps, car ils ne sont que faiblement liés à La structure du tissu. In general, when a fabric, which is not essentially made of waterproof synthetic fibers, is brought into contact with water, it remains impregnated and takes on a darker color. There are also waterproofing agents for the surface treatment of fabrics, but these products have a very reduced effectiveness over time, because they are only weakly linked to the structure of the fabric.
La présente invention a pour but d'utiliser de manière avantageuse le phénomène de changement de teinte par imprégnation des toiles ou tissus tout en évitant les problèmes liés au vieillissement des agents hydrofuges. The present invention aims to advantageously use the phenomenon of color change by impregnation of fabrics or fabrics while avoiding the problems associated with the aging of water-repellent agents.
Ce but est atteint, conformément à l'invention au moyen d'une composition hydrophobe comprenant
- de 5 à 30 % d'un agent hydrofuge
- de 3 à 5 % d'un agent épaississant
- de 3 à 5 % d'une résine thermocondensable
- de 2 à 3 % d'un catalyseur de polymérisation de la résine thermocondensable, le reste étant de l'eau. This object is achieved, in accordance with the invention by means of a hydrophobic composition comprising
- from 5 to 30% of a water repellent
- 3 to 5% of a thickening agent
- 3 to 5% of a thermally condensable resin
- from 2 to 3% of a polymerization catalyst for the thermally condensable resin, the rest being water.
Selon des caractéristiques avantageuses de l'invention, la résine thermocondensable est une résine mélamine-formol ;
ledit agent épaississant comprend une fine dispersion d'une solution aqueuse d'un copolymère acrylique dans un solvant organique et ledit agent hydrofuge est choisi parmi les composés fluorés solubles ou miscibles dans l'eau. According to advantageous characteristics of the invention, the thermally condensable resin is a melamine-formaldehyde resin;
said thickening agent comprises a fine dispersion of an aqueous solution of an acrylic copolymer in an organic solvent and said water-repellent agent is chosen from fluorinated compounds which are soluble or miscible in water.
Un autre objet de la présente invention est un procédé de fabrication de motifs hydrofuges sur un tissu caractérisé en ce que
on prépare, en solution aqueuse, une composition hydrophobe comprenant
- de 5 à 30 % d'un agent hydrofuge tel qu'un composé fluoré soluble ou miscible dans l'eau,
- de 3 à 5 % d'un agent épaississant,
- de 3 à 5 % d'une résine thermocondensable,
- de 2 à 3 % d'un catalyseur de polymérisation de ladite résine thermocondensable, le reste étant de L'eau,
on applique ladite composition aqueuse sur le tissu non traité
on sèche ladite composition sur le tissu à une température comprise entre 100 et 1100C,
on fixe ladite composition par chauffage d'une durée comprise entre 30 s et 5 min à une température comprise entre 150 et 180 C. Another object of the present invention is a process for manufacturing water repellent patterns on a fabric characterized in that
a hydrophobic composition comprising, in aqueous solution, comprising
- from 5 to 30% of a water-repellent agent such as a fluorinated compound soluble or miscible in water,
- from 3 to 5% of a thickening agent,
- from 3 to 5% of a thermally condensable resin,
from 2 to 3% of a polymerization catalyst for said thermocondensable resin, the rest being water,
applying said aqueous composition to the untreated fabric
said composition is dried on the fabric at a temperature between 100 and 1100C,
said composition is fixed by heating for a duration of between 30 s and 5 min at a temperature of between 150 and 180 C.
Les tissus ou toiles à motifs fabriqués avec le procédé et la composition de L'invention présentent une teinte unie à L'état sec et des différences de teinte entre les motifs hydrofuges et le reste du tissu à L'état humide ce qui procure un effet esthétique certain. The fabrics or fabrics with patterns produced with the process and the composition of the invention have a solid color in the dry state and differences in color between the water-repellent patterns and the rest of the fabric in the wet state which gives an effect certain aesthetics.
De plus, les motifs hydrofuges fabriqués par le procédé de L'invention ne vieillissent pas et conservent Leur tenue et leurs propriétés hydrophobes même après de nombreux lavages du tissu. In addition, the water-repellent patterns produced by the process of the invention do not age and retain their resistance and their hydrophobic properties even after numerous washes of the fabric.
L'invention sera mieux comprise à la lecture de la description qui va suivre avec un exemple de réalisation. The invention will be better understood on reading the description which follows with an exemplary embodiment.
Selon L'invention on prépare tout d'abord, en solution aqueuse, une composition hydrophobe comprenant de 5 à 30 % d'un agent hydrofuge choisi de préférence parmi les composés fluorés solubles ou miscibles dans l'eau mélangé avec une quantité de 3 à 5 % d'un agent épaississant constitué d'une fine dispersion d'une solution aqueuse d'un copolymère acrylique dans un solvant organique de haute pureté. On ajoute ensuite de 3 à 5 % d'un haut polymère constitué d'une résine thermocondensable, de préférence d'une résine mélamine-formol puis de 2 à 3 % d'un catalyseur de polymérisation de ladite résine. According to the invention, firstly, in aqueous solution, a hydrophobic composition is prepared comprising from 5 to 30% of a water-repellent agent preferably chosen from fluorinated compounds soluble or miscible in water mixed with an amount of 3 to 5% of a thickening agent consisting of a fine dispersion of an aqueous solution of an acrylic copolymer in an organic solvent of high purity. Then added from 3 to 5% of a high polymer consisting of a thermally condensable resin, preferably a melamine-formaldehyde resin and then from 2 to 3% of a polymerization catalyst for said resin.
On obtient ainsi une pâte aqueuse que l'on applique sur le tissu non traité. An aqueous paste is thus obtained which is applied to the untreated fabric.
L'application de la composition hydrophobe sur le tissu est effectuée par impression en continu ou par sérigraphie en définissant des motifs prédéterminés. The application of the hydrophobic composition to the fabric is carried out by continuous printing or by screen printing by defining predetermined patterns.
On sèche ensuite la composition pour faire disparaître le mi lieu aqueux. The composition is then dried to make the aqueous medium disappear.
Le séchage est effectué de préférence en chauffant par tous moyens connus à une température comprise entre 100 et 1100C. The drying is preferably carried out by heating by any known means to a temperature between 100 and 1100C.
On fixe ensuite la composition sur le tissu par réticulation du liant polymère obtenue en chauffant pendant une durée comprise entre 30 s et 5 min à une température comprise entre 150 C et 170 C. The composition is then fixed on the fabric by crosslinking of the polymer binder obtained by heating for a period of between 30 s and 5 min at a temperature between 150 C and 170 C.
L'agent hydrofuge est ainsi piégé au sein des mailles ou fibres constituant le tissu au moyen de la résine thermocondensable polymérisée. The water-repellent agent is thus trapped within the meshes or fibers constituting the fabric by means of the polymerized thermally condensable resin.
Exemple
On prépare une composition hydrophobe en solution aqueuse en mélangeant - 30 % de Foraperl 35 ffi (agent hydrofuge) fabriqué par
La Société ATOCHEM (Fr),
- 5 % de Texipoli (épaississant) fabriqué par la
Société SCOTTBADER (USA), qui se présente sous la forme d'un
Liquide crémeux dont la densité est de 1,05 à 20 C et qui est compatible avec des polymères anioniques,
- 5 % de Proxef e (résine thermocondensable) fabriqué par la Société PROTEX (Fr),
- 3 % de fixateur H(FH) (catalyseur) fabriqué par la
Société ELLETTA (Italie) qui se présente sous la forme d'un liquide incolore.Example
A hydrophobic composition in aqueous solution is prepared by mixing - 30% of Foraperl 35 ffi (water-repellent agent) manufactured by
The ATOCHEM Company (Fr),
- 5% Texipoli (thickener) manufactured by the
SCOTTBADER company (USA), which is in the form of a
Creamy liquid with a density of 1.05 to 20 C and which is compatible with anionic polymers,
- 5% of Proxef e (thermally condensable resin) manufactured by the company PROTEX (Fr),
- 3% of fixative H (FH) (catalyst) manufactured by the
ELLETTA company (Italy) which is in the form of a colorless liquid.
On complète jusqu'à 100 % avec de l'eau. Make up to 100% with water.
La composition se présente sous la forme d'une pâte aqueuse. The composition is in the form of an aqueous paste.
On applique cette composition sur une toile ou tissu de coton à 100 %, non traité, c'est-à-dire exempt de tout produit à l'exception des teintures, en formant des motifs. This composition is applied to a 100% cotton canvas or fabric, untreated, that is to say free from any product except dyes, by forming patterns.
La composition est ensuite séchée sur le tissu par chauf fage, par exemple en four, à une température inférieure à 1100C. The composition is then dried on the fabric by heating, for example in an oven, at a temperature below 1100C.
Puis, on fixe la composition en effectuant une polymérisation ou réticulation de la résine polymère Proxefpar chauffage pendant 5 min à une température voisine de 1800C.Then, the composition is fixed by carrying out a polymerization or crosslinking of the Proxef polymer resin by heating for 5 min at a temperature in the region of 1800C.
On obtient ainsi des motifs parfaitement invisibles lorsque le tissu de support est à L'état sec et qui se distinguent seulement lorsque le support textile est à L'état humide. We thus obtain perfectly invisible patterns when the support fabric is in the dry state and which are distinguished only when the textile support is in the wet state.
En présence d'eau, les motifs conservent leur couleur initia le alors que le tissu s'assombrit, leur caractère hydrofuge hydrofuge empêchent localement l'imprégnation du tissu. In the presence of water, the patterns retain their original color while the fabric darkens, their water-repellent water-repellency locally prevents the impregnation of the fabric.
