Definitions

  • the present invention relates to a process for treating a laundry item.
  • the present invention also relates to a cleaning product for laundry.
  • Laundry cleaning products are extremely well known. Usu ⁇ ally a composition in the form of a liquid or powder is added to a laundry washing machine, either directly to the drum or via a dispenser, and washing is carried out using an appropriate selection from a number of pre-programmed cycles. Accurate dosing may be a problem, particularly when consumers do not read or follow the dosing instructions. Recently products in the form of laundry composi- tions packaged in a film of water-soluble polymer have become available. However, alternative methods of presentation of unit-dosed products are desired. Furthermore, there may be a preconception in the minds of some consumers that the polymer may not dissolve fully or that the polymer might dissolve before the product is added to the wash. Additionally the product is perceived as being fragile, and it lacks versatility in use.
  • compositions for pretreating a laundry item for example to remove a stain or to assist in stain removal, are also known.
  • Such compositions are, for example, in the form of a liquid composition which may be applied directly to the laundry item, for example, by spraying.
  • Such compositions need to be rinsed off with water after use, for example, by hand or in a laundry washing ma ⁇ chine .
  • active agents in the form of a solid preferably in the form of a powder
  • can be used to remove soils from laundry which do not need to be rinsed off with water after use, but can be easily brushed off by the user.
  • a laundry product having an enclosing wall and containing a composition in the form of a powder, said com- position comprising an insoluble active agent which is capable of binding soil, the wall being permeable to water and to components dissolved therein, wherein, after the product has been contacted with water in a laundry washing machine, the insoluble active agent remains with attached to the enclosing wall, characterised in that the product has a re-sealable portion.
  • the laundry product of the present invention combines the advantages of a unit-dose product with an active agent which is capable of binding soil or "soil catcher" product.
  • a further advantage is that contact of the hands of a user and the detergent (which is often caustic/corrosive) is avoided.
  • An advantage of the present invention is that the cleaning product is more versatile since the enclosing wall can have an additional function.
  • the product can be contacted with or rubbed on laundry before it is added into the laundry washing machine. In this way a pre-treatment can be carried out depending on the nature of the product.
  • the cleaning product has an enclosing wall which is permeable to water and to components dissolved therein.
  • the enclosing wall may also be permeable to oils and other soil or stain components suspended or dispersed in water. How- ever, the wall is impermeable to the powder held within the product .
  • the enclosing wall may be have a portion which is insoluble and permeable to water, and another portion which is in- soluble and impermeable to water.
  • a user may hold the product by the impermeable wall section and, for example, press the permeable wall section directly with the stain. In this way, contact between the user's hands and the contents of the enclosing wall is avoided.
  • water permeable we mean having a water permeability of at least 1000 l/m 2 /s at 100 Pa according to DIN EN ISO 9237.
  • the wall must not be so permeable that it is not able to hold the powder composition.
  • the wall may have a mesh size of less than 250 microns, preferably less than 150 microns, more preferably less than 50 microns.
  • the product should not be able to move out of the drum, such as by entering the internal pipework of the washing machine and onto the filter.
  • it is generally large, preferably having a minimum length and width of at least 120 mm.
  • the product is preferably flat, i.e. its thickness is at least 5 times less, preferably at least 10 times less, ideally at least 30 times less, than each of its other two di- mensions, the width and the length (which are the same as each other when the product is square or circular in plan) .
  • the product may contain an insert to act as a bulking aid. Such an insert can assist in preventing the (open) sachet from leaving the drum of the washing machine.
  • the insert is preferably affixed to an enclosing wall, preferably on the interior thereof; e.g. by an adhesive or by being disposed in an additional flap/pocket of wall material.
  • the insert may be a sponge material, e.g. a cubic/rectangular sponge having dimensions in the range of 10-20mm.
  • the product may be formed into a flat container or a sachet.
  • the sachet may measure at least 2 cm across. Pref- erably, the sachet measures at least 10 cm across.
  • the sachet is preferably sufficiently large for it to be held conveniently by hand and applied directly to the soiled laundry item.
  • re-sealable opening comprises a portion of the sachet which is releasably held together with sealing material / mechansim.
  • the sealing material / mechansim is intended to be able to be opened by a user such that the contents of the sachet can be replenished after use, i.e. af- ter the content of the sachet have been allowed to dissolve / dispserse in the wash liquor.
  • the sealing material / mechanism preferably comprises a re- sealable seal such as a Velcro type seal or a seal closed by a draw string.
  • the sachet may be formed from a sandwich of two webs.
  • a water permeable sheet or film is present in one of the webs, at least, and forms at least one wall of the container.
  • the water-permeable outer wall may comprise, for example, a woven, knitted or preferably non-woven material, of textile, polymer or paper. Suitable polymers include cellular polymer materials.
  • the material may be in the form of single layer or laminated layers.
  • the wall comprises a sheet with a ply of one, two or three layers, such that any non-dissolved or insoluble agent inside the container is too large to pass through the perfora- tion(s) or would have to follow an impossibly tortuous pathway if it were to exit the container through the wall.
  • the sheet is a woven or non-woven material.
  • the product may conveniently comprise two webs sealed to- gether about their periphery, with the contents held inside.
  • the sealing may be by means of adhesive or dielectric welding or, preferably, heat sealing or, most preferably, ultrasound sealing.
  • the sheets may comprise a thermoplastic to facilitate this.
  • the material forming the adhesive strips can be a so called hot melt comprising various materials, such as APP, SBS, SEBS, SIS, EVA and the like, or a cold glue, such as a dispersion of various materials, e.g. SBS, natural rubber and the like, or even a solvent-based or a two-component adhesive system.
  • the material may be capable of crosslinking to form specific, permanent chemical bonds with the various layers.
  • Polyethylene glycols with different molecular weights can be used as well, having average molecular weights ranging from 1000 to 20000, most pre- ferred ones are from 2000 to 8000.
  • the amount of adhesive used is a function of the type of adhesive selected. However it is generally from 0.2 to 20 g/m 2 .
  • the sealing material / mechanism may be employed along a portion of the periphery of the seal between the webs of material so that the integrity of the seal is affected upon contact with the wash liquor. Alternatively the sealing material / mechanism may be employed at a portion of the centre of the web material, i.e. forming a separate sealed area/ opening.
  • the two webs are non-wovens .
  • Processes for manufacturing nonwoven fabrics can be grouped into four general categories leading to four main types of nonwoven products, textile-related, paper-related, extrusion-polymer processing related and hybrid combinations.
  • Textiles include garneting, carding, and aerodynamic forming of fibres into selectively oriented webs. Fabrics produced by these systems are referred to as drylaid nonwovens, and they carry terms such as garneted, carded, and airlaid fabrics. Textile-based nonwoven fabrics, or fibre-network structures, are manufactured with machinery designed to manipulate textile fibres in the dry state. Also included in this category are structures formed with filament bundles or tow, and fabrics composed of staple fibres and stitching threads. In general, textile-technology based processes provide maximum product versatility, since most textile fibres and bonding systems can be utilised.
  • Paper-based technologies include drylaid pulp and wetlaid (modified paper) systems designed to accommodate short synthetic fibres, as well as wood pulp fibres. Fabrics produced by these systems are referred to as drylaid pulp and wetlaid nonwovens . Paper-based nonwoven fabrics are manufactured with machinery designed to manipulate short fibres suspended in fluid.
  • Extrusions include spunbond, meltblown, and porous film systems. Fabrics produced by these systems are referred to individually as spunbonded, meltblown, and textured or aperture film nonwovens, or generically as polymer-laid nonwovens. Extrusion-based nonwovens are manufactured with machinery associated with polymer extrusion. In polymer-laid systems, fibre structures simultaneously are formed and manipulated.
  • Hybrids include fabric/sheet combining systems, combination systems, and composite systems. Combining sys- terns employ lamination technology or at least one basic nonwoven web formation or consolidation technology to join two or more fabric substrates. Combination systems utilize at least one fabric substrate. Composite systems integrate two or more basic nonwoven web formation technologies to produce web structures. Hybrid processes combine technology advantages for specific applications.
  • Suitable materials for forming the enclosing wall are paper or a polyolefin, such as polyethylene or polypropylene, or another polymer such as a polyester or polyamide.
  • the enclosing wall comprises a water-permeable, water- insoluble web, preferably of one or a mixture of the above materials.
  • the enclosing wall is preferably a woven or non-woven web.
  • the materials making up the enclosing wall are preferably in the form of fibres.
  • the surface of the enclosing wall may be subjected to co ⁇ rona or plasma treatment or a permanent chemical treatment, for example with cationic polymers. All these treatments may give rise to an increase in the affinity of organic molecules to the substrate through ionic or polar interac- tion. By doing this the free stain molecules in the wash liquor are captured by the wall of the product which work as a filter, reducing the stain re-deposition on fabrics.
  • the enclosing wall may also be formed of a cellular plas- tics material.
  • Suitable cellular plastics for forming the enclosing wall have densities of 1 to 500 kgirf 3 , preferably from 20 to 80 kg ⁇ f 3 and with an average pore diameter of at least 0.1 mm, preferably at least 0.4 mm.
  • the cellular plastics has a porosity of greater than 50%, pref- erably greater than 60%, more preferably greater than 70%, most preferably greater than 80%.

  • Suitable cellular plastics materials are those readily available for example from Euro foam, Miarka and Menshen and are made from any suitable water-insoluble plastic such as cellulose, polyurethane, polyester, polyether, or blends thereof.
  • the product of the present invention may have an enclosing wall which has a roughened outer surface.
  • the roughened outer surface may be provided by the wall being in the form of woven or non-woven fibres. The roughness of the surface depends on, for example, the diameter of the fibres.
  • the roughened outer surface may also be provided by ensuring that an otherwise uniform outer wall has a surface texture. This could be provided, for example, by including particu- late matter in the wall or by forming the wall in an appropriate manner.
  • a roughened outer surface may provide a number of advantages. For example, it ensures that the product is less likely to slip out of a consumer's hand, particularly when the product is damp and hence slippery.
  • the product may simply be contacted with or rubbed on the laundry, especially a stained part thereof, to treat the laundry before washing, for example to remove a stain or assist in stain removal.
  • Some of the cleaning composition from inside the product may leach outside to assist in this pre-treatment . It is also possible for an additional agent to be attached to the outside of the product.
  • the enclosing wall of the product may be a cellulosic material, for example a cellulosic textile or paper material.
  • the product may be placed with the laundry to be washed in an automatic laundry washing machine.
  • the closed product preferably resists a laundry wash cycle (2h wash/rinse/spin cycle, 95°C, spinning at 1600rpm) without opening.
  • the product may be discarded after use.
  • the product may also be used in a stain treating step prior to placing into an automatic laundry washing machine.
  • the product may be wet with water and used directly onto the stain by a scrubbing action.
  • the com- position starts to dissolve, it may be released through the enclosing wall or container to the treated garment area.
  • the laundry product may be placed in a bucket with water and the stained laundry. After soaking the laundry for a predetermined period of time, the laundry may be removed. In one embodiment, the laundry is allowed to soak a period of time ranging from 1 minute to overnight, preferably from 10 minutes to 6 hours.
  • a method for treating a laundry item which comprises contacting the laundry item with a cleaning composition in the form of a solid comprising an insoluble ac- tive agent that is capable of binding soil, such that soil on the laundry item is bound to the insoluble active agent, and removing "the composition from the laundry item, option ⁇ ally in the absence of water.
  • the laundry item is contacted with the cleaning composition when it is freshly soiled.
  • the cleaning composition may be applied to the laundry item within 30 minutes of the soil occurring, preferably within 10 min- utes, for example within 1 minute.
  • the laundry- item may be wetted or moistened to assist the cleaning composition to contact the stain.
  • composition may then be left on the soiled area for sufficient time to allow the insoluble active agent to bind or "catch" the soil/stain particles (by the use of the term soil hereinafter we also includes stains) . This may take less than 1 hour, for example less than 30 minutes, preferably less than 10 minutes.
  • composition is then removed from the laundry item.
  • the composition is removed in the absence of water, for example, by brushing the composition off the laundry item.
