Definitions

  • the invention especially relates to a fiber having non-ignition properties which can be applied to create a yarn, a thread, a woven, knit, or non-woven textile having non-ignition properties
  • One of the properties one may wish to give a fabric is flame resistance.
  • Many of the chemicals used to impart flame resistance to textile materials, especially to thermoplastic textile substrates are not water soluble and thus are usually applied by padding as aqueous dispersions or emulsions.
  • Aqueous dispersions of water-insoluble, non-phosphorus-containing brominated aromatic or cycloaliphatic organic compounds and a metal oxide together with a latex or other binder are described in U.S. Pat. No. 4,600,606.
  • These dispersions or emulsions require high levels of dispersing agents, surfactants, and sometimes organic solvents, in order to function effectively. Even so, dispersion or emulsion stability is often very concentration dependent and sensitive to the presence of other additives in the application bath. Also, the dispersing agents, surfactants, and especially the organic solvents can cause other difficulties in the treatment process, for example color loss of a dyed substrate being finished.
  • Flame retardant systems for synthetic or natural polymers can act physically and/or chemically by interfering at particular stages of burning. For example: endothermic processes triggered by the flame retardants cool the substrate; fewer pyrolysis gases are evolved and oxygen is excluded by impeding heat transfer; substances which evolve inert gases on decomposition dilute the fuel in the solid and gaseous phases and the concentrations of combustible gases fall under the ignition limit; interrupting the free radical mechanism of combustion processes; and accelerating the breakdown of polymers.
  • Coating powders and powder-coating processes offer a number of significant advantages: they are essentially 100% non-volatile and no solvents or other undesired substances are given off during application and curing; the powders are ready to use and require no thinning or dilution with the attendant need for organic solvents; and they do not require complex emulsion or dispersion formulation. Coating thickness, and therefore flame resistance, can be easily controlled and the powder is well utilized. Overspray can be collected or filtered from the surrounding atmosphere and reapplied, an important consideration when the material applied is costly.
  • Halogenated organic flame retardants are further classified as containing either chlorine or bromine, i.e., Brominated Flame Retardants (BFR).
  • Antimony oxide is another important component of a flame retardant composition, containing a halogen, particularly chlorine and bromine. It is totally ineffective if used without a halogen.
  • the tri oxide is the common material used although the pentoxide can also be used.
  • the pentoxide has a much finer particle size and is more effective per unit weight added than the trioxide.
  • Polyesters are very sensitive to residual acidity in all forms of antimony oxide. Alkaline salts of antimony oxides are used in these critical cases. Antimony oxide acts as a synergist with chlorine and bromine.
  • Antimony tribromide is a dense, white product and is one of the main components of the typical white smoke that is seen from burning polymers containing a halogen and antimony oxide. High levels of water from normal combustion causes reversion of SbBr 3 to HBR and Sb2U3. The remaining antimony oxide is then available to react with fresh HBR from a decomposing brominated compound. Typically compounds used in flame retardant applications contain either 40 to 70 % chlorine or 45 to 80% bromine.
  • the molecule should be water-insoluble to achieve durability in laundering. A solvent soluble organic molecule will give better results.
  • the ortho-phosphate group should be present in the molecule to catalytically dehydrate the cellulose substrate.
  • the molecule should contain polymerizable groups to affect a permanency of finish.
  • the molecule should contain a halogen or other groupings to reduce the flammability of the gases of decomposition.
  • US Patent 7736696 Piana, et al discusses the deposition of FR compounds on a fiber, yarn, or textile through a system similar to the application of a dye in a vat under pressure.
  • EP20090160876 Rock, Moshe discusses the inclusion of a fire retardant (FR) fiber in a knitted or woven fabric that is in a fleece formation so that the FR element is on the outside of the fabric. The technology discussed is applied to a finished textile.
  • FR fire retardant
  • PCT/US1999/021616 Rearick et al discusses the binding mechanism of a carboxylic acid-containing compound and a suitable catalyst for coupling the compound to some or all of the hydroxyl groups present on the materials and esterifying the hydroxyl groups to all allow for attachment of a fire retardant compound on cellulose.
  • U.S. patent 4552803 to Pearson relates to fire retardant compositions in the form of a powder that are produced from the following components: TBL _Component Parts by Weight aldehyde 70-140 ammonium phosphate 50-250 ammonium, alkali metal or 50-250 alkaline earth metal compound or salt urea reactant 70-190 hydroxy reactant 20-60 phosphoric acid 150-250. Also provided are retardant compositions containing the powder and methods for treating substrates, such as paper or wood, as well as cotton, wool, and synthetic textiles to impart fire retardant properties thereto.
  • U.S. patent no. 4990368 relates to flame retardant properties which are imparted to a textile substrate by application of a powdered flame retardant in solid form, which is then fused or melted onto the textile to durably attach the flame retardant to the textile.
  • the process is especially adapted for water insoluble solid flame retardants, such as hexabromocyclododecane, currently applied in dispersion or emulsion form.
  • the fiber to be treated is carried by a conveyor throughout the surface cavitation process.
  • the length of the conveyor used is a factor in determining the amount of time taken to expose the fiber to the insoluble chemical.
  • the method of applying an insoluble chemical to a fiber can take place in as little as 15 minutes and preferably in less than one hour. It has been found that no more than 10% of a treated fiber in any application is necessary to render a textile produced from these fibers effective.
  • the fibers are first treated by surface cavitation before being formed into a textile.
  • the present invention also relates to a fiber and resulting textiles made from any fibers which have been treated in accordance with the method described herein. These fibers can be natural or artificial and cellulosic or polymeric.
  • Antibacterial fabrics are widely used for production of outdoor clothes, underwear, bed-linen, and bandages. Antimicrobial resistance is very important in textile materials, having effects amongst others on comfort for the wearer.
  • the deposition of metal oxides known to possess antimicrobial activity, namely zinc oxide, magnesium oxide and copper oxide, can significantly extend the end uses of textile fabrics and prolong the period of their use.
  • rollers are preferably placed no less than every meter to assure that the fibers remain submerged.
  • the transducers are activated just before the sliver and water and hydrated compound are added to the conveyor belt. The transducers will continue their work the length of the conveyor belt which is adjusted to assure an even coating over 100% of the fibers. After the coating is complete the loose fibers are then quickly squeezed to remove almost all the water but more importantly to solidify the sliver once again so that it will have its own integrity which will allow it to be moved to the drying station.
  • the chemical compound can be attached to the substrate using a sonochemical process as described above. According to the present invention there is also provided a way of using a sonochemical process for the addition of the chemical to the substrate while producing a soft fabric that has apparel applications as opposed to a sonochemical plated product which is very rough to the hand and inappropriate for apparel end-uses.
