Definitions

  • the present invention relates to the treatment of a textile and / or fibers for the manufacture of a textile, for the purpose of administering to a subject at least one pharmaceutical or cosmetic active principle by contact between the textile and the textile. skin of the subject.
  • Grafting techniques are known which, if they make it possible to control the problems of exhaustion and resistance to washing, prohibit any reloading by the consumer, since these grafting techniques require reagents and conditions for treating the fibers and / or textiles that can not be implemented by the end user.
  • this type of fixation underlies that the active ingredients are fixed durably, which is not appropriate for cosmeto-textiles, since it is sought, in this technical field, to release easily active principles.
  • impregnation techniques are conventionally used for the treatment of fibers and / or textiles to permanently fix additives such as dyes and dyes that are not intended to be salted out.
  • US 2005/0132500 A1 describes insecticidal compositions in solid or aqueous forms, comprising an insecticide and an acrylic binder, obtained by emulsion polymerization, and intended to impregnate fibers and / or textiles and / or plastic materials.
  • FR 2838459 A1 textile materials in the field of clothing or furniture impregnated by the so-called ionization recoil process for reloading the active ingredient after washing, said active ingredient being applied by spraying, after preheating in a humidified atmosphere saturated with water and application of one or more substances in solution or dispersion after addition of a binding agent or adhesion agent.
  • This technique makes it possible to fix active ingredients for a duration equal to at least three days.
  • microencapsulated textile technique allows the attachment of active ingredients by fixing microcapsules on the textile.
  • the microcapsules are indeed individualized microparticles consisting of a coating polymeric material containing an active ingredient.
  • the size of a microcapsule is between 1 ⁇ m and 1 mm. The capsule will allow the release of the active ingredient by rupture, for example by friction of the envelope or by slow diffusion through the membrane whose porosity will change over time.
  • microencapsulation technique requires the use of a binder to fix the microcapsules on the fibers and / or textiles, and this because of their low affinity for them; their voluminous size, making insertion into the heart of the fibers difficult, only leads to impregnation on the surface.
  • this microencapsulation technique requires the presence of polymeric capsules, which will accumulate in the textile and cause a phenomenon of fiber poisoning, as well as possible problems of intolerance, if these microcapsules are used to provide active ingredients on the skin.
  • the present invention therefore relates to a process for treating a textile and / or fibers for the manufacture of a textile, said textile being intended for administration to a subject of at least one pharmaceutical or cosmetic active principle by contact between said textile and the skin of the subject characterized in that:
  • At least one active ingredient in the form of nanoparticles is available in an aqueous solution, said textile is impregnated with
  • the present invention also relates to a textile and / or fibers impregnated with at least one cosmetic or pharmaceutical active ingredient that can be obtained by the process for treating a textile and / or fibers according to the invention.

  • the textiles may be non-woven, woven or knitted textiles. They consist of natural or synthetic fibers alone or mixed. Natural fibers are selected from cotton, wool, silk and / or jute.
  • the synthetic fibers are chosen from polyamides, polyesters, polyacryl nitrites, polyolefins such as polypropylene or polyethylene or Teflon.
  • the fibers can be spun, carded or twisted.
  • the fibers may have been treated with the treatment method according to the invention for the manufacture of a textile, or the textile has been treated with the method according to the invention.
  • textiles treated according to the method according to the invention can be used for the manufacture of clothing, gloves, footwear, underwear, stockings, tights, as well as medical articles such as bandages, splints dressings, compresses, bandages, masks.
  • the textiles used in the context of the present invention which are thus impregnated with at least one active ingredient, are resistant to washing, it is possible to cover the fibers of which said textiles are made of a thin film, acting as a protective sheath and covering the nanoparticles of active ingredients.
  • This sheath will disintegrate gradually in contact with the subject wearing the textile, as well as during the various washes, which will allow the release, spaced in time, at least one active ingredient on and / or in the skin that is found between the textile fibers and surrounded by this sheath.
  • the amount of nanoparticles used is between 10 and 50 g of nanoparticles per kg of fibers and / or textiles.
  • the impregnation of the textile and / or fibers can be carried out by dipping and / or spraying. In one embodiment of the present invention, the impregnation is carried out by dipping at a temperature of between 20 and 60 ° C.
  • the aqueous solution may comprise other additives chosen from preservatives, antibacterials, fillers, defoamers, antistatic agents, stabilizers and antioxidants.
  • the aqueous solution may also include fireproofing agents, plasticizers, pigments, as well as those which will allow the formation of a protective sheath around the fibers of which the textile is made.
  • the impregnation protocol may be the following.
  • the impregnation is carried out on fibers and / or a dried textile, after possibly an enzyme treatment.
  • the weight of particles used is 20 g per kg of fiber and / or textile.
  • the bath used comprises 1 kg of fibers and / or textile for 20 liters of water.

  • the fibers and / or the textile are added to the water optionally containing other additives which have been mentioned above.
  • the temperature of the assembly is raised to around 40 ° C.
  • the nanoparticles are added to the mixture in one or more times.
  • the fixation of the particles can be observed by decreasing the turbidity of the aqueous medium.
  • the mixture is left stirring for about 30 minutes. After emptying, the fibers and / or the textile are dewatered and dried at a temperature below 50 ° C.
  • the treatment method according to the present invention can be carried out on a textile that has been washed and / or brought into contact with the skin, and therefore for which the at least one active ingredient has been salted out.
  • the object is to re-impregnate the textile, which can be achieved by spraying the textile of the at least one active principle. Spraying can be carried out using an aqueous solution containing said at least one active principle.
  • This spray has the further advantage that it can be targeted to particular areas of the textile that are in contact with the parts of the body on which the at least active ingredient must act in a preferred manner. To illustrate this, one can cite the example of underwear or footwear for which only certain parts of the textile will be treated.
  • a use of the textile treatment method according to the present invention may consist in controlling and / or following the release onto and / or in the skin of the at least one active principle by means of a textile control label. which has been impregnated with dye nanoparticles.
  • the amount of dye nanoparticles must be adjusted in such a way that the discoloration of the control label is proportional to the release of the at least one active principle from which the textile is impregnated. It is thus possible to evaluate the quantity of the at least one active ingredient salted out by the visualization of the discoloration of the control label.
  • a new label which may be provided with the container of the refill emulsion, or which is produced directly by the user, and this by spraying with the aid of a control emulsion which will comprise therefore the dye nanoparticles.
  • This method of control and / or monitoring has the advantage of avoiding unwanted reloads that can be dangerous and result in overdoses of active ingredient. Also, this makes it possible to precisely follow the exhaustion curve which depends on the conditions of exposure and / or wearing of the textile, as well as the washing conditions.
