Definitions

  • the invention is in the field of sustained release of active ingredients, in particular for the finishing of fibers and fabrics.
  • the term "wearing comfort” summarizes the increased demands of the consumer, who no longer wants to be satisfied with the fact that the clothes he wears directly on the skin, such as lingerie or tights, neither scratch nor cause reddening of the skin, but are expected in the opposite way. that it has a positive effect on the condition of his skin. This can be either to remedy fatigue, as well as to convey a fresh scent or to avoid skin roughness. There has therefore been no lack of efforts to equip textiles, for example, women's tights, with cosmetic agents that merge when wearing on the skin and there cause the desired effects.
  • Database WPI Week198848 (AN 1988-343069) and JP 63-256769 disclose a textile provided with a mixture of loaded porous microcapsules and film-forming polymers.
  • Database WPI Week199019 (AN 1990-142321) and JP 02-084595 discloses a material that releases insecticides; it contains porous three-dimensional microcapsules that make an insecticide.
  • US 2006/0264547 A1 describes refractory superabsorbent polymexes that can absorb many times their own weight in water. It also discloses a blend of superabsorbent microspheres loaded with flame retardant agents and a film forming binder.
  • EP 1,600,210 Al describes loaded microspheres. It involves loading microspheres with active ingredients and then applying the loaded microspheres to textile surfaces where they are physically adsorbed without the use of binders. Although in this technical solution, a certain wash resistance is given, but this does not meet the highest requirements.
  • WO 2006/015718 A1 describes fibers and fabrics which are characterized by being blended with mixtures of (a) hydrophobic actives and (b) binders.
  • binders are agents without the mediation of microcapsules or the like applied to Textilobef lake, but not directly, but by means of film-forming polymers (binders). This technical solution lacks a controlled release of the active ingredients.
  • wash permanence is to be understood that the above-mentioned desirable properties of the textiles are lessened by washing only to a limited extent.
  • microspheres (a) are unloaded. They fulfill the function that they can be loaded by the user as desired and, after release of the active ingredients, can also be reloaded as desired.
  • Absorbent microspheres are structures that have a largely homogeneous structure.
  • the absorbent microspheres used in the context of the present invention have the property of being able to absorb and also release active substances, both of which can be done several times, ie. Active substances can be absorbed by loading or reloading and released again over time. Because of this property, these microspheres are referred to as absorbent microspheres.
  • the term "absorbent" (* capable of taking active ingredients) will be omitted below and simply referred to as microspheres.
  • the active ingredients can be adsorbed on the surface of the microspheres and / or dissolved in the microspheres and / or in the microspheres e.g. be embedded in fine channels.
  • Microspheres are dimensionally stable, i. they are not destroyed in the release of the active ingredients. It should be expressly stated that microcapsules, which are indeed destroyed in the release of the active substances, do not fall under the definition of microspheres.
  • microspheres are fixed by - one or more - film-forming polymers on the textile surface, resulting in a relative to the prior art, relative improvement of the washing permanence.
  • microspheres are preferably spherical in shape, but are not limited in geometry to spheroidal shape, but may have other spatial shapes, for example, they may represent rotatiosellipsoids or have a rod shape.
  • the microspheres preferably have an average particle size in the range of 1 to 15 microns, and more preferably 5 to 10 microns.
  • microsphere based on polymethylmethacrylate is used.
  • PMMA polymethylmethacrylate
  • examples are, for example, Covabead LH 85 or LH 170 from the company LCW or Cosmedia PMMA V8, Cosmedia PMMA V 12 or Cosmedia SILC from Cognis.
  • silicone-based or SiO 2 -based microspheres are used.
  • examples are "Dow Corning 9509 Silicone Elastomer Suspension” from Dow Corning.
  • microspheres based on polymethylmethacrylate are used.
  • Suitable polyurethanes (PU) and polyethylvinyl acetates (EVA) are, for example, the commercially available products from the Cognis 3011-A or Cognis 3009-A range from Cognis.
  • Polymeric melamine compounds Melamine (synonym: 2,4,6-triamino-1,3,5-triazine) is usually formed by trimerization of dicyandiamide or by cyclization of urea with elimination of carbon dioxide and ammonia.
  • melamine refers to oligomeric or polymeric condensation products of melamine with formaldehyde, urea, phenol or mixtures thereof.
  • glyoxals are understood as meaning the self-condensation products of glyoxal ("polyglyoxals").
  • Silicone compounds are, for example, dimethylpolysiloxanes, methylphenylpolysiloxanes, cyclic silicones and amino, fatty acid, alcohol, polyether, epoxy, fluorine, glycoside and / or alkyl-modified silicone compounds which are preferably solid or resin-form at room temperature.
  • simethicones which are mixtures of dimethicones having an average chain length of from 200 to 300 dimethylsiloxane units and hydrogenated silicates.
  • Particularly preferred is the use of aminosiloxanes, eg Cognis 3001 from Cognis. Their further crosslinking with H-siloxanes, eg Cognis 3002 from Cognis, can further increase the performance as a binder.
  • Poly (meth) acrylates are homo- and copolymerization products of acrylic acid, methacrylic acid and optionally their esters, especially their esters with lower alcohols, such as methanol, ethanol, isopropyl alcohol, the isomeric butanols, cyclohexanol and the like to understand which are obtained in a conventional manner, for example by free-radical polymerization under UV irradiation.
  • the average molecular weight of the polymers is between 100 and 10,000, preferably 200 and 5,000 and especially 400 to 2,000 daltons.
  • the binders (b) - based on the component (a) - in amounts of 0.5 to 15, preferably 1 to 10 and especially 1 to 5 wt .-% applied to the fibers.
  • Component (a) is to be understood as meaning the microspheres in unloaded form.
  • active ingredients that are intended to load the microspheres are not critical per se and depends exclusively on which effect is to be effected on the skin.
  • active ingredients are preferred which have moisturizing properties or counteract cellulite.
  • Typical examples are tocopherol, tocopherol acetate, tocopherol palmitate, carotenes, caffeine, ascorbic acid, (deoxy) ribonucleic acid and their fragmentation products, ⁇ -glucans, retinol, bisabolol, allantoin, phytantriol, panthenol, AHA acids, amino acids, ceramides, pseudoceramides, chitosan, dihydroxyacetone , Menthol, squalane, essential oils (eg lavender oil, lemon oil, eucalyptus oil or peppermint oil), vegetable oils (eg Monoi de Tahiti, shea butter, almond oil, passion fruit oil, rosehip seed oil or apricot oil), vegetable proteins and their hydrolysis products, plant extracts, such as Extracts of Ginkgo biloba, Camellia sinensis, Trifolium pratensis, Oleacea europensis, Litchi sinensis, Valeriana oficinalis, Medicago s
  • the active compounds from the group formed by essential oils, vegetable oils, squalane, chitosan, menthol, retinol (or vitamin A), caffeine, vegetable or animal proteins and their hydrolysis products, carotenes and jojoba oil.
  • the weight ratio between the component (a) - such as the finely divided PMMA - and the active ingredients is 10: 90 to 99: 1, preferably 3: 1 to 1: 1 and more preferably about 2: 1.
  • the "Covabed LH 85" microspheres were converted into a 10% by weight aqueous dispersion using the "Cognis 6003-A” surfactant in demineralized water.
  • the dispersing unit used was an Ultra-Turrax type agitator).
  • the dispersion thus prepared contained 10% by weight of PMMA microspheres.
  • the dispersion is hereinafter referred to as DISP-1.
  • PA / EL 76/24%) knit (knit fabric in which the yarn is made of 76% polyamide and 24% spandex (e.g., Lycra)) was impregnated with the following solution (liquor) by means of a laboratory padder:
