Definitions

  • the invention relates to a process for treating fabrics.
  • the user is instructed to: 1) completely remove spots and stains prior to placing garments in the bag, preferably by placing the absorbent pad under the garment; 2) add one to four garments to the bag; 3) insert a pre-moistened cloth into the bag containing the garments; 4) seal the bag; 5) tumble the bag, garments and cloth in the dryer for 30 minutes at medium to high heat; and 6) hang the garments promptly to help decrease wrinkling.
  • Users of the Dryel product have complained about the need for a bag and its limited capacity and the potential for entrapment, rather than removal, of particulates . Also, the use of the bottle/pad combination to remove stains adds to the complexity of the process.
  • a fabric treatment process of the type which employs a carrier sheet having a treatment composition impregnated thereon, which process involves the steps of placing one or more fabric articles in the dryer along with the carrier sheet, and carrying out a drying operation, the process being characterised in that an additional soil adsorbant material is added to the dryer.
  • oil adsorbant material should be understood as including materials which are specifically designed to exhibit electrostatic properties, and materials which act to neutralise, decompose or otherwise deodorise odours.
  • an electrostatically adsorbing material are electret media. This term is used to describe fibrous air filtration media whose individual fibres carry an electrostatic charge, while the media as a whole, is neutral .
  • the electret media When added to a dryer in the process of the invention, the electret media will act to remove particulate soil, dust, hair, microbes and the like from the fabrics and from the dryer itself. In this regard the soil may transfer directly from the fabrics being treated to the electret material, or the soil may initially be taken up by the turbulent air within the machine from which it is filtered by the electret media.
  • an electret material is Flo-CleanTM produced by AFFCO.
  • the electret material may be provided in the form of a fabric sheet which is simply added to the dryer along with the fabrics to be treated and the carrier sheet . In such cases the sheet may have a thickness of between 10 and 1000 microns.
  • the electret sheet may be bonded or otherwise attached to the carrier sheet, such as for example a backing sheet.
  • the electret fibres are used in the manufacture of the carrier sheet by being woven intimately with the carrier sheet substrate fibres.
  • an odour neutralising material is the product is " Neutrafelhacrin "TM which is produced by Mitsubishi Synthetic Fibres Co and which comprises a deodorising polyacrylonitrile fibre.
  • the fibre has powdered chitosan added during production of the raw fibres.
  • a further example of such a material is produced by Kurary/ Takeda under the Trade Name "Shine Up” , which material comprises a fibre having a ceramic based material which removes odours on exposure to light specifically by converting aceto-aldehydes present in mal -odours to acetic acid, which then reacts with substances such as ammonia within the caramic .
  • the doedorising fibres of the invenbtion may act by either adsorbtion or chemical breakdown of adours .
  • the deodorising fibres may be added to the dryer as part of the carrier sheet, or as part of a doedorising fabric sheet. Indeed, the separate sheet may comprise some deodorising fibres and some electret fibres .
  • the process includes the step of placing the fabrics and carrier sheet in a bag, before placing the bag in the dryer.
  • the bag comprises means for containing the fabrics and carrier sheet while permitting airflow through the bag.
  • the bag may be a net bag.
  • the net bag may have a mesh size of between 1 and 100mm.
  • the carrier sheet comprises a defined tear-off portion.
  • the carrier sheet may comprise a single- ply non-woven sheet, such as for example a hydroentangled rayon/polyester mix.
  • the carrier sheet will carry from 10 to lOOg of treatment composition, typically between 20 and 60g, and ideally approximately 40g.
  • the treatment composition includes at least perfume and detergent.
  • the composition comprises an anti -wrinkling agent.
  • One particularly suitable anti-wrinkling agent is marketed under the Trade Name Silwet.
  • the invention also relates to a home dry cleaning kit comprising a carrier sheet and one or more soil adsorbing materials according to the invention.
  • the kit may also include additional fabric treatment composition, or a containment bag, or both.
  • wrinkle reduction Several molecules have been identified for wrinkle reduction and other benefits, such as static reduction benefits when included on one of the above- identified substrates and used on clothing in a dryer.
  • AATCC American Association of Textile Chemists and Colorists
  • the following molecular classes were found to be effective on test cloths: ethoxylated organosilicones; polyalkyleneoxide modified polydimethylsiloxane; linear aminopolydimethylsiloxane polyalkyleneoxide copolymers; sulfated/sulfonated vegetable oils; high molecular weight polyacrylamides; betaine siloxane copolymers; and alkylactam siloxane coplymers .
  • the most preferred wrinkle reducing agent is a polyalkyleneoxide modified polydimethyl siloxane sold under the name Silwet L-7622, available from Witco,
  • Adogen 66 a tallow alkyl BIS (polyethoxy) ethyl ammonium, ethyl sulfate, also available from Witco can be used in combination with one or more of the above compounds to reduce static. Use with Silwet L-7622 is preferred.
  • One or more of the molecules/compounds from the above- identified classes are preferably formulated in an amount from about 0.1 wt % to about 5 wt % and most preferably from about 0. 3 wt % to about 1.5 wt %. Particularly preferred examples are set forth, below.
  • a preferred method of measuring wrinkle reduction is by using the American Association of Textile Chemists and Colorists 1 (AATCC) method # 124, Appearance of Fabrics after Repeated Home Laundering.
  • AATCC American Association of Textile Chemists and Colorists 1
  • four cloth types silk, rayon, cotton, and linen
  • the dried cloths are then evaluated for wrinkle content by comparison with wrinkle smoothness replicas, which can be purchased from AATCC.
  • Factors such as the light used, the angle of the cloths and replicas to the light, and the background are carefully controlled and described in the method.
  • the substrate having formulation absorbed therein is preferably enclosed in a hermetically sealed pouch.
  • the pouch will preferably inhibit egress of the chemical agents and inhibit ingress of bacteria and other foreign matter.
  • One or more of the pouches can be packed in an enclosed carton for commercial sale.
  • the pouch is preferably manufactured from a heat sealable, foil laminate material.
  • the user simply removes the substrate from the packaging, separate a tear-off portion from the body of the carrier sheet, and use the tear off portion to pre-treat the clothes by rubbing it against the soiled areas as needed.
  • the pre-treated clothes and remainder of the carrier sheet are placed in the dryer while the tear-off portion is discarded.
  • One or more soil adsorbant sheets may then be added to the dryer.
  • a separate electret fabric sheet is added to the machine.
  • a drying operation is then carried out. Agents will act on the clothing to reduce wrinkles, reduce odors, reduce stains and/or reduce static.
  • particulate soil on the clothes and in the machine will be adsorbed onto the electret fabric.
  • the soil is directly adsorbed onto the electret.
  • the process as previously discussed, is effective and suitable for use on relatively dry clothing.
  • the dirt picked up during the pre-treatment step is removed from the main treatment operation.
  • the invention is not limited to the embodiments hereinbefore described which may be varied in both construction, detail and process step without departing from the spirit of the invention.
  • the invention may include the addition of both electret and odour neutralising materials into the dryer with the fabrics.
