Definitions

  • the present invention relates primarily to a wiping product suitable for use in the disinfection of hard surfaces, instruments and human or animal skin.
  • Such disinfection is accomplished by applying a disinfectant chemical or formulation to the surface, instrument or skin and accommpanying this by spreading the disinfectant using a wiping material to ensure uniform coverage and therefore disinfection.
  • a disinfectant chemical or formulation comprising cloths, sponges, pads or other substrate materials which are either impregnated with disinfectant or retain a disinfecting agent within one or more pockets formed in the substrate material.
  • These products are usually either pre-moistened in their packaging or require to be dampened before use.
  • United States Patent Specification No. 4,259,383 describes a tissue incorporating a disinfecting agent capable of generating hydrogen peroxide when wet.
  • the disinfecting agent is sealed within a single pocket made between two layers of adsorbent non-woven paper and, in a second example, the disinfecting agent is sealed within a series of rhomboidally shaped pockets uniformly distributed over the length of the paper tissue.
  • the disinfectants that it is practical to use to impregnate such wipes have hitherto been limited and those used have not had a sufficient spectrum of activity, that is the ability to kill quickly and efficiently the more resistant micro-organisms such as Mycobacterium tuberculosis, Hepatitis B virus, Parvovirus, or Polio virus.
  • the object of the present invention is primarily to provide a product suitable for use as a disinfecting wipe which overcomes the afore-mentioned disadvantage and which has a useful shelf-life.
  • a product comprising a non-woven substrate having entrapped within its structure solid particles which, when dampened with a suitable liquid, become active and characterised in that the non-woven substrate has been lofted to form a matrix of fibres and in that the solid particles comprise a chlorine release agent and are substantially uniformly distributed throughout and entrapped within the matrix by the fibres forming the substrate.
  • the chlorine release agent becomes active when dampened with water.
  • the chlorine release agent may, for example, comprise one or more of the following chemicals: calcium hypochlorite; chlorinated tri-sodium phosphate; N,N dichlorazo-dicarbonamidine; sodium p toluene sulphon-chloramide; p toluene sulphondichloramide; sodium benzene sulphonchloramide; succinchlorimide; p-sulphon-dichloramidobenzoic acid; 1,3 dichloro-5-5 diethyl hydantoin; trichloro-isocyanuric acid; sodium dichloroisocyanurate; sodium dichloroisocyanurate dihydrate; potassium dichloroisocyanurate; or trichloromelamine.
  • chlorine release agents can be used which are either solid or which may be rendered as powders or granules by adsorption on to a suitable carrier.
  • a chlorine release agent may be used in combination with other compounds such as a detergent, for example sodium alkylbenzene sulphonate, or sodium Iauryl sulphate, or a detergent builder, for example sodium carbonate, sodium, metasilicate, or sodium sulphate.
  • a detergent for example sodium alkylbenzene sulphonate, or sodium Iauryl sulphate
  • a detergent builder for example sodium carbonate, sodium, metasilicate, or sodium sulphate.
  • Other compounds which may be used in this way include superabsorbent polymers, fragrances, perfumes or dyes.
  • a dye may be incorporated into the substrate so that it is bleached by the activated particles and thereby provides a visual indication of the status of the product with regard to the exhaustion of the product's disinfecting properties.
  • the loftable nonwoven substrate is laminated on one or on both sides with another material through which the solid particles are unable to pass.
  • This laminate material may, for example, comprise either a nonwoven or a textile material, or paper, or a sponge material, or a plastics film depending on the use for which the product is designed. In some cases, it may be preferable for the laminate material to be hydrophobic and impermeable or alternatively a high water absorption may be desirable.
  • the major purpose of this invention is to provide a product suitable for wiping and disinfecting surfaces, it is possible to utilise a product of similar physical characteristics for other purposes. For example, it could be used as a sheet inclusion in a washing process for the quantitative release of chlorine either for the purpose of disinfection or bleaching.
  • the loftable non-woven substrate employed is a non-woven fabric comprising a carded web of fibres bonded together with a thermoplastic material, which, when heated to the softening point of the binding material, will transform into a high loft, even density structure.
  • the loftable nature of the fabric is achieved by the use of crimped fibres which are held in a compact form by the thermoplastic bonding material, usually a low temperature adhesive polymer, and which on heating of the fabric to soften the bonding material spring apart to form an even density matrix.
  • Different textile fibres can be used but preferred fibres are polyester or viscose or combinations of polyester with viscose or other cellulosic fibre.
  • Such substrates are available commercially under the trade name ULTRALOFT .
  • any non-woven material capable of trapping solid particles could be used as the substrate of the product.
  • the substrate comprises a 48 grams per square metre polyester bonded material which is laminated with a 24 grams per square metre polyester dry lay non-woven material.
  • the combined material is firstly passed beneath a medium wave infra-red heater in order to loft the substrate layer and then subjected to a uniform scattering of particulate sodium dichloroisocyanurate dihydrate over the lofted substrate.
  • the particles are of a size within the range of 200 - 750 microns inclusive so that they penetrate the substrate to give an available chlorine content of 5,000 ppm when activated by absorption of the product's maximum level of water.
  • the second example utilises a substrate comprising a 40 gram per square metre rayon fibre nonwoven material bonded by a polyester thermoplastic. This substrate is laminated with a 24 gram per square metre polyester dry-lay nonwoven material. As in the first example, the substrate is lofted by infra-red heat but the substrate is then stretched by passing it over a bowed roller in order to increase temporarily the openness of the substrate's structure. During this stretching, the substrate is subjected to a uniform scattering of a powder formulation comprising 95% sodium dichloroisocyanurate dihydrate and 5% sodium alkyl benzene sulphonate. The powder penetrates the stretched substrate and is then trapped when the stretching ceases and the substrate is relaxed. Sufficient powder penetrates the substrate in this example to give an available chlorine content of 1,000 ppm when activated by absorption of the product's maximum water level.
  • the substrate comprises a 108 gram per square metre 100% polyester material which is again lofted by medium wave infra-red heat.
  • a powder composition comprising sodium dichloroisocyanurate dihydrate together with a proportion of a superabsorbent polymer, such as is commercially available under the trade mark SALSORB of Allied Colloids PLC, is then rolled into the substrate so that penetration of the lofted substrate by the powder occurs. Sufficient powder penetration can be achieved to give an available chlorine content of 100 ppm when the product has absorbed its maximum level of water.
  • the integrity of the finished product may be further influenced by a partial resealing or compacting of the lofted substrate. This may be achieved by pressure or by a combination of heat and pressure, for example by a suitable arrangement of nip rollers.
  • a visual indicator is incorporated into the wipe to show the status of the disinfecting capability of the wipe at any given time.
  • a visual indicator can be incorporated into the product by dyeing all or portions of the substrate with a dye which is bleached at a known rate by the chlorine released once the wipe is used.
  • the indicator dye gradually fades or disappears from the substrate at a similar rate to the rate at which the proportion of unreleased chlorine within the wipe decreases during use.
  • suitable dyes have been found amongst those capable of dyeing cellulosic fibres, for example amongst the so-called "reactive dyes".
  • suitable dyes are marketed by
  • the substrate used in the product of the invention is dyed with one or more stripes of the dye ot dyes before being lofted and impregnated with the chlorine releasing particles.
  • the dyeing process can, therefore, form a stage in the production process of the product, as described in the above examples, and the use of cold acting reactive dyes is advantageous in this regard.
