Definitions
- the present invention relates to a cleaning product such as a cleaning cloth, for instance a floor cleaner and a cleaning glove, based on a textile structure and more particularly to a cleaning product with a textile structure in which substantially no cleaning products such as soaps, emulsifiers, solvents (anti-)foaming agents and the like are included in order to provide or enhance the product cleaning properties.
- the textile structure provides the product with its cleaning properties.
- the textile structure such as a knitted material, woven material, non-woven or brush, comprises fibres which are cut on at least one side of the structure, whereby microfibres are formed protruding from this side which provide the textile structure with the cleaning properties.
- Such cleaning products can be used in the household, in the sauna, the office and the workplace to clean skin, objects, tools and floors.
- the cleaning product retains its cleaning action for a long period and can be washed regularly, for example five to ten times. It has nevertheless been established that the appreciation of the cleaning product and its cleaning action decrease due to colour change, odour formation and accumulation of alien material.
- the present invention has for its object to change the cleaning product such that the appreciation increases and the above described undesired effects are avoided as far as possible, while there is substantially no adverse effect on the cleaning properties, let alone that it is required that additional means must be added to the finished cleaning product by the user.
- a cleaning product according to the invention for cleaning contaminated surfaces comprising a textile structure of fibres, wherein fibres are provided with an agent with biocidal action.
- Providing the fibres with the biocidal agent achieves that bacteria/mould accumulating in the vicinity of the fibres are inhibited in their growth and possibly even killed.
- Understood by a biocidal agent is an agent which inhibits the growth of and/or kills bacteria/mould. Not every biocidal agent can be used since according to the invention it is required that the biocidal agent is incorporated into or fixed on the textile structure.
- Use can for instance be made of a biocidal metal or metal compound such as water-insoluble metal salts.
- Suitable metals comprise copper, copper powder and copper salts.
- the quantity of biocidal agent for adding to the textile structure depends on the application of the cleaning product, the type of fibre of the textile structure and the nature of the biocidal agent per se.
- a quantity of biocidal agent in the textile structure is usually sufficient of about 0.001-10% by weight, preferably 0.020-7% by weight, in general 0.050-5% by weight.
- the biocidal agent may only be necessary for the biocidal agent to be present in a part of the fibres which then provide the biocidal action to the whole of the textile structure into which they are woven or knitted.
- the biocidal agent can be incorporated in the fibres, wherein they are incorporated in the matrix of the fibres.
- the biocidal agent can be released on the surface through wear of the fibres and be transferred to the cleaned surface.
- the biocidal agent can be arranged on the surface of the fibres in substantially irreversible manner physically or chemically, whereby these fibres are provided with a coating with the biocidal agent.
- the biocidal agent is incorporated in the fibre matrix it is recommended that the biocidal agent is added during the formation (extrusion/spinning) of the fibres (synthetic fibres) or during the preparation of the fibres (natural fibres).
- the biocidal agent can be applied by means of a physical process or coated thereon via an immersion in a solution containing the biocidal agent.
- fibres which are provided with the biocidal agent do not have to have the same chemical composition as the fibres used to form the textile structure.
- Fibres which are suitable for incorporating the biocidal agent are for example polyester fibres, nylon fibres, acryl fibres and cotton fibres, wool fibres and cellulose fibres insofar as they can be bonded to the biocidal agent physically or chemically in substantially irreversible manner. It is possible to use specifically cleaning fibres and specifically biocidal fibres.
- the textile structure comprises microfibres protruding from the textile structure and contains substantially no cleaning agent.
- the drawback occurs that water drips from the cleaning product and can come into contact with the user. Under these conditions it is recommended that the textile structure comprises water-retaining fibres whereby this dripping of liquid out of the cleaning product is substantially avoided.
- the cleaning product can have a textile structure based on a woven or knitted material.
- a woven material has a very rigid structure in the direction of the warp and weft threads and is therefore suitable for products whose dimensional stability is a requirement, such as floor cleaners and cleaning gloves.
- the textile structure consists of a knitted material, the looped threads of which are suitable for absorbing the stresses at the position of the curve.
- the cleaning product consists of a textile structure on the basis of a woven and/or knitted material.
- Very suitable cleaning products according to the invention take the form of a floor cleaner which can be arranged on a floor plate operated by a handle or a cleaning glove into which the user places his hand and carries out the cleaning operations on the object with the hand.
- Very many biocidal agents can be used for the cleaning product according to the invention insofar as they do not damage the health of the user and his surroundings.
- a suitable group of biocidal agents is formed by quaternary ammonium compounds which are currently applied in disinfectants. These agents can be applied by immersion to the fibres for inclusion in the fibre structure or the textile structure can be immersed integrally therein. These compounds adhere to the fibre surface and leach at a very low speed. The leaching speed can be further slowed by increasing the cohesion to the fibres or by providing the biocidal agent with a functional group which can be covalently bonded to fibre material.
- biocidal agents is formed by metal ions and metal particles with biocide activity (for instance copper), which metals are bonded substantially irreversibly to the fibres in an inorganic or organic compound/complex; the metal particles are for instance incorporated in the fibre matrix and are released gradually during fibre wear.
- metal ions and metal particles with biocide activity for instance copper
- fibres Understood by fibres are threads, yarns and the like which can consist of monofilaments and multifilaments, wherein the biocidal agent can be arranged on the fibre itself or on its filament, or can be enclosed in the fibre matrix or between the fibre filaments.
- a textile structure in the form of a weave is woven from polyester fibres and the woven material is cut on one side, thereby resulting in microfibres protruding on this side.
- This textile structure in the form of a strip is guided through an immersion liquid containing a quaternary ammonium compound such as alkyldimethylbenzyl ammoniumchloride.
- the alkyl group preferably has a very long carbon chain whereby the cohesion to the polyester fibre surface is high.
- Dodigen 226 (trademark Hoechst) can for instance be used in a solution of 3-5% by weight.
- the manufactured cleaning product displays a good biocidal action which decreases gradually with prolonged use and interim washing.
- the duration of use due to the non-occurrence of colour change and odour formation as well as accumulation of alien material is considerably lengthened.
- Acryl fibres or nylon fibres are impregnated by corona discharge with copper sulphide which is chemically adhered to the fibre surface. These acryl and nylon fibres are subsequently co-knitted in the manufacture of a textile structure based on polyester fibres, whereafter the textile structure is further processed as according to example 1 so as to obtain microfibres on this side.
- the acryl or nylon fibres form only 0.005 to 0.5% by weight of the textile structure while an excellent, substantially permanent biocidal action is obtained.
- fibres are also interwoven whereof the fibre matrix is provided with a biocidal agent, for instance a sodium aluminosilicate incorporated in the matrix to which copper is added (Diolen, trademark Akzo).
- a biocidal agent for instance a sodium aluminosilicate incorporated in the matrix to which copper is added (Diolen, trademark Akzo).
- These biocidal fibres are interwoven in a quantity by weight of for instance 0.01-10 % by weight, such as 0.2-8% by weight, in particular 0.3-5% by weight of the textile structure.
- Viscose fibres are further interwoven which provide the textile structure with an increased water-retaining capacity.
- a polyethylene master-batch is co-extruded with copper powder (0.1-100 ⁇ m) such that the obtained extrudate contains copper (grains) in a quantity by weight of for example 5-30% by weight.
- a co-extrusion of the copper extrudate subsequently takes place with polyethylene whereby fibres are spun which contain copper as biocide in a concentration by weight of 0.1-3% by weight.
- a cleaning product can be woven which contains fibres containing only copper particles or a mixture of copper particle-containing fibres and other polyester fibres. It is moreover possible to apply instead of polyester fibres other fibres, for example water-absorbing natural fibres.
- fibres contain a high concentration of copper particles it is possible to use typical cleaning fibres as additional fibres, whereby the cleaning action is substantially unaffected by the addition.
- An advantage of this embodiment is that the metal particles are originally present in the matrix and are released by wear of the fibre during the cleaning of surfaces and are partly transferred to the cleaned surface, thereby resulting in a preventive cleaning.
- the cleaning product according to example 1 can preferably be applied in a floor cleaner, while the cleaning products of examples 2 and 3 can also be applied in the cleaning gloves.
- the cleaning product according to example 4 is suitable for both applications.
