Definitions

  • the present invention relates to methods of and materials for protecting fibers and fabrics or textiles and the like from both fading and other deletereous effects of ultra-violet radiation and from the soiling effects of water, oil and other soiling elements.
  • the art is replete with ultra-violet radiation screening or stabilizing agents for incorporation with synthetic fibers and other articles useable to form fabrics for household furnishings and other purposes and articles of clothing and the like that are to be protected from fading, degradation, deterioration and discoloring by the ultra violet rays.
  • US-A-3 888 821 (disclosing the use of a substituted benzotriazole, benzophenone or triazine, for example, absorbed in an aromatic polyamide fiber); US-A-3 379 675 (disclosing benzotriazole and a tris-phenol, for example, for stabilizing polyether-based spandex fibers); and 4 251 433 (disclosing the coating of the extruded organic fibers or other articles with heterocyclic ester ultra-violet stabilizers).
  • the mechanism for such screening action is believed to reside in one or more of filtering action or preferential absorption of deleterious incident wavelengths with dissipation through heat fluorescence or similar phenomena.
  • UV-screening compounds are "spun-in” prior to fiber extrusion, sometimes “dyed in”, sometimes “coated-on”, and sometimes microdispersed. Similar compounds have also been used for UV-absorption when applied to the human skin (US-A-3 004 896, for example) and to photographic dye images and the like (US-A-4 447 511 and 4 308 328, as illustrations).
  • An object of the invention accordingly, is to provide a new and improved method of and composite material for simultaneously imparting ultra-violet screening and absorbing properties and fluid and soil repellent properties to organic and related fibres and fabrics or textiles, and without sacrificing the desired hand, coloration, flexibility or other original properties of the same.
  • a further object is to provide a thin solidified admixed layer or coating imparting such novel properties.
  • a method of simultaneously providing UV screening and fluid and soil repellent properties to organic fibre fabrics and the like comprising combining a fluid and soil repellent solution with a UV screening compound soluble in and non-reactive with said solution characterised in that said repellent solution is selected from the group consisting of acrylates and fluoropolymers, and the UV screening agent is selected from the group consisting of o-hydroxybenzonphenones and o-hydroxyphenylbenzatriazole, thoroughly dissolving the said screening compound in the repellent solution in a ratio range from 2-30% and 98-70% to provide sprayable particles, and spraying the same as a thin deposit upon the fabric.
  • the present invention provides a novel composition of matter containing an appropriate ultra-violet screening agent combined with a suitable water-repellent coating, formulated so that the composition can be applied to the surface of a variety of substrates, especially dyed fabrics, to protect them simultaneously from photodegradation and from staining as by various soiling agents, with the compoisition being applied by spraying or coating, to maximise efficiency.
  • Preferred and best mode steps and materials are hereinafter set forth.
  • underlying the invention is the discovery that a particular combining of ultra-violet screening agents and fluid and soil repellent agents, and the thin film application thereof to preferably organic fibre fabric or textile materials, for example, can result in the simultaneous imparting of both fade-resistant (and other deterioriation) properties and resistance or repellence to wetting or soiling.
  • compositions comprise from about 2% to 30% of the screening agent (preferably hydroxyl benzotriazoles) in about 98% to 70% of preferably a binder as of the fluorinated type used in 3M's "Scotchguard” trademark product (see, for example, 3M US-A-3 981 928 and 4 043 923) or Dupont's polyfluorinated polymers marketed under the trademark "Teflon”.
  • the screening agent preferably hydroxyl benzotriazoles
  • a binder as of the fluorinated type used in 3M's "Scotchguard” trademark product (see, for example, 3M US-A-3 981 928 and 4 043 923) or Dupont's polyfluorinated polymers marketed under the trademark "Teflon”.
  • hydroxybenzophenones e.g., Cyasorb 24, sold by American Cyanamid Co., etc.
  • fluorinated binders as well as binders which lack fluorine, but possess similar functional properties, i.e., hydrophobic character (e.g. polystyrene methyl methacrylate), can also be used.
  • the weight percentage is based on solid binder, which may contain a plasticizer.
  • the spray composition may contain a fugitive dye which will permit the user to determine which areas of the surface have been sprayed.
  • useful fugitive dyes are conventional indicator dyes, in combination with a volatile base, e.g., a mixture of phenpohthalein with ammonia, or well-known oxygen-reactive color fading dyes.
  • acrylate solution (Rohm & Haas B72) was mixed with Riedel-DeHaen AG film and plastic discoloration UV inhibiter compounds Type HMB ("Riedel” (2-hydroxy-4-methoxybenzophenone) soluble in and non-reactive in the acrylate solution, in the ratio of approximately 4 parts to 98 parts of acrylate solution, and the combination was thoroughly admixed and mutually dispersed.
  • the mixture was reduced with solvent to spraying viscosity.
  • the same was then sprayed from an atomizing spray device in droplets of average size of about 5 microns as a thin layer (of the order of about 20 microns) on dry polyester fabric, and permitted to dry in an adhered thin film form.
  • the fabric was subjected to ultra-violet rays from a carbon arc lamp for 100 hours with noticeable improvement in fading properties. Water and oil droplets applied to the protected fabric were readily wiped off without strain both before and after the UV tests.
  • Tinuvin 343 Another Ciba-Geigy o-hydroxyphenylbenzotriazole UV absorber (“Tinuvin 343”) was mixed in the same "Scotchguard” type repellent solution of Example 2 (20% solids) and stirred to get all of the UV-absorber into solution, but in the ratio of 2 grams of T-343 to 50 grams of repellent solution.
  • the solution was placed in a 100 ml bottle attached to a Chromist Spray apparatus (Gelman Instrument Co., Ann Arbor, Michigan), and a fine spray of several micron particle size was directed on dyed fabric (of nylon and cotton and polyester fibers) of red, blue and yellow colors for comparison with (1) unsprayed areas of the fabric and (2) unsprayed fabric areas fronted with an opaque cardboard layer.
  • a screening agent of o-hydroxybenzophenones ("Cyasorb 24" of American Cyanamid Co.) dissolved in "Scotchguard” fluorinated binder in the ratio of 7 to 93%, and spray-dried upon fabric.
  • Example 3 The formulation of Example 3 with a fugitive dye indicator (phenophthalein-ammonia) to show the sprayed areas combined with an ammonia volatile base.
  • a fugitive dye indicator phenophthalein-ammonia
  • thymolphthalein indicator may be used that changes from blue to colourless on pH change.
  • UV screening elements of the type of the T-109 and T-343, etc. preferred limits of weight per unit area are from about 0.18 milligrams/sq cm (0.1 gm/ft2) to about 1.8 milligrams/sq cm (1 gram/ft2), if slight yellowing is not desired. For brown or red coloured fabrics that do not show the yellowing or shade shift, up to several milligrams can be used.
  • the preferred limits of the "Scotchguard" type repellent is up to about 3.2 milligrams/sq cm (3 grams/ft2) depending upon the degree of repellency protection desired.
  • the dried spray particle combination layer indeed, appears to make more effective use of the UV absorber than without the repellancy product combined therewith.
