Description
Textile bio-actif comportant dans ses fibres de la protéine de soie et desBio-active textile containing in its fibers silk protein and
microcapsules de produit actif La présente invention concerne un textile bio-actif, c'est-à-dire un textile auquel un traitement approprié a conféré des propriétés particulières particulièrement intéressantes quand ce textile est destiné au contact avec la peau. Ces propriétés peuvent10 être par exemple antibactérienne, fongicide, parfumante, hydratante, antistatique, etc. De nombreuses techniques ont été proposées pour conférer les propriétés souhaitées soit aux fibres constituant le textile soit au textile lui-même. Parmi15 ces techniques, on peut citer le greffage chimique d'agents actifs, le greffage par faisceau d'électrons, l'introduction d'agent dans une fibre synthétique avant son extrusion, l'application d'apprêt sur la fibre, l'incorporation de microcapsules. 20 On peut se reporter par exemple au brevet européen 89101701.4 ou au document US 4,234,627 A qui décrivent des techniques d'incorporation de microcapsules dans les textiles. Par ailleurs, on connaît l'utilisation de protéine de soie dans les fibres naturelles ou synthétiques, par exemple par les documents FR 2 645 884 A, EP 0 557 043 A, EP 0 761 867 A et US 5,514,737. L'effet usuellement noté de la protéine de soie est l'amélioration du toucher de la fibre ou du textile,30 avec l'obtention d'un effet particulier de confort et de douceur rappelant la soie. Dans le cadre d'une utilisation sur des collants, on a noté un effet antidésséchant (EP 0 761 867 A). La présente invention repose sur la découverte que les propriétés conférées au textile par microcapsules of active product The present invention relates to a bio-active textile, that is to say a textile to which an appropriate treatment has given particular properties which are particularly advantageous when this textile is intended for contact with the skin. These properties can be, for example, antibacterial, fungicidal, perfuming, hydrating, antistatic, etc. Numerous techniques have been proposed for imparting the desired properties either to the fibers constituting the textile or to the textile itself. Among these techniques, mention may be made of the chemical grafting of active agents, the electron beam grafting, the introduction of agent into a synthetic fiber before its extrusion, the application of primer on the fiber, the incorporation microcapsules. Reference may be made, for example, to European patent 89101701.4 or to document US 4,234,627 A which describe techniques for incorporating microcapsules in textiles. Furthermore, the use of silk protein in natural or synthetic fibers is known, for example from the documents FR 2 645 884 A, EP 0 557 043 A, EP 0 761 867 A and US 5,514,737. The effect usually noted of silk protein is the improvement in the feel of the fiber or of the textile, with the obtaining of a particular effect of comfort and softness reminiscent of silk. In the context of use on tights, an anti-drying effect has been noted (EP 0 761 867 A). The present invention is based on the discovery that the properties imparted to textiles by

la protéine de soie sont améliorées quand le textile comprend également au sein de ses fibres des microcapsules d'un produit actif, notamment d'un produit hydratant. On constate que la combinaison des5 deux produits permet non seulement de prévenir le dessèchement cutané et d'hydrater les couches the silk protein are improved when the textile also includes within its fibers microcapsules of an active product, in particular of a hydrating product. It is found that the combination of the two products not only prevents skin dryness and hydrates the layers
superficielles de l'épiderme, mais permet de prolonger cette action avec efficacité au-delà de ce qui était connu. Le mécanisme de cette synergie n'est pas encore10 complètement expliqué. superficial of the epidermis, but allows this action to be prolonged effectively beyond what was known. The mechanism of this synergy is not yet fully explained.
Des expériences nombreuses ont été conduites par la Demanderesse sur des collants en polyamide/élasthanne. La protéine de soie utilisée dans le traitement du textile est l'agent de finition15 commercialisé par IDEMITSU PETROCHEMICAL CO. Sous la référence TF, se présentant sous la forme d'une émulsion de poudre de protéine (5-10%) et de résine de polyuréthanne (10-20%) dans de l'eau. L'agent actif utilisé a été une formule hydratante (mélange glycéro20 stéridique d'origine végétale) encapsulée dans des microcapsules en polymère synthétique fixées sur le textile par un liant de type polysiloxane. Les expérimentations ont été réalisées sur des groupes de 10 sujets volontaires sains, chaque sujet étant son propre témoin. L'étude était effectuée jambe droite traitée versus jambe gauche témoin, dans des conditions standardisées. Le collant était lavé chaque soir et réutilisé le lendemain, et l'hydratation de la peau était mesurée chaque jour pendant cinq30 jours. La quantification de l'état d'hydratation était réalisée par la méthode atraumatique de la capacitance Numerous experiments have been carried out by the Applicant on polyamide / elastane tights. The silk protein used in the treatment of textiles is the finishing agent15 sold by IDEMITSU PETROCHEMICAL CO. Under the reference TF, in the form of an emulsion of protein powder (5-10%) and polyurethane resin (10-20%) in water. The active agent used was a hydrating formula (sterile glycero20 mixture of plant origin) encapsulated in microcapsules of synthetic polymer fixed on the textile by a binder of polysiloxane type. The experiments were carried out on groups of 10 healthy volunteer subjects, each subject being its own control. The study was carried out on the treated right leg versus the control left leg, under standardized conditions. The tights were washed every evening and reused the next day, and skin hydration was measured daily for five30 days. The hydration state was quantified by the atraumatic capacitance method
cutanée à l'aide d'un cornéomètre. L'analyse statistique des résultats a été effectuée au moyen du test t-Student apparié bilatéral et unilatéral. using a corneometer. The statistical analysis of the results was carried out using the bilateral tilated test and unilateral.

Une première série d'expérimentations a porté sur des collants traités par des microcapsules de A first series of experiments focused on tights treated with microcapsules of
produit hydratant seules, dans diverses concentrations. Cette série a confirmé l'action hydratante obtenue5 ainsi que l'effet dose dans les fourchettes de concentration étudiées. moisturizing product alone, in various concentrations. This series confirmed the hydrating action obtained5 as well as the dose effect in the concentration ranges studied.
Une deuxième série d'expérimentations a porté sur des collants traités par les protéines de soie seules, et a confirmé l'effet anti-désséchant sur la10 peau entraîné par le port quotidien du collant: sur les jambes traitées, le taux d'hydratation reste inchangé aux troisième, quatrième et cinquième jour alors que les jambes non-traitées présentent aux mêmes jours une légère mais significative déshydratation.15 En combinant conformément à l'invention des microcapsules de produit actif et des protéines de soie, on a constaté une remarquable prolongation de l'effet hydratant. En traitant la jambe gauche avec ladite combinaison et en traitant la jambe droite avec20 des microcapsules seulement (utilisées dans une même quantité), on a observé au cinquième jour une augmentation de l'hydratation de 7,74% par rapport à l'origine sur la jambe gauche, alors qu'elle n'était que de 4,45% sur la jambe droite.25 Dans une autre série d'expérimentations, on a comparé les effets de l'application d'un lait corporel sur une jambe, le premier jour seulement, avec les effets du port régulier du collant conforme à l'invention. Hormis au premier jour o l'effet du lait30 hydratant est notablement supérieur à celui du collant (augmentation de l'hydratation de 15% avec le lai contre 7% avec le collant traité), du deuxième jour au cinquième jour les effets sont sensiblement identiques avec une hydratation moyenne statistiquement augmentée A second series of experiments focused on tights treated with the silk proteins alone, and confirmed the anti-drying effect on the skin caused by the daily wearing of the tights: on the treated legs, the rate of hydration remains unchanged on the third, fourth and fifth day while the untreated legs show a slight but significant dehydration on the same days.15 By combining, according to the invention, microcapsules of active product and silk proteins, a remarkable prolongation has been observed. hydrating effect. By treating the left leg with said combination and treating the right leg with only microcapsules (used in the same amount), an increase in hydration of 7.74% was observed on the fifth day compared to the original on the left leg, when it was only 4.45% on the right leg.25 In another series of experiments, we compared the effects of applying body milk on one leg, the first day only, with the effects of regular wearing of the tights according to the invention. Except on the first day when the effect of the moisturizing milk30 is significantly greater than that of the tights (15% increase in hydration with the lai versus 7% with the treated tights), from the second day to the fifth day the effects are substantially identical with statistically increased average hydration
de 6 à 7 % dans les deux cas.from 6 to 7% in both cases.
