Definitions

• the present invention relates to a covering article for beds and the like, as well as to a method for making it.
• the invention relates to a mattress protector; nevertheless, in general, it also relates to other covering articles for beds and the like such as quilts, cushions, filling materials for the latter, bedspreads, sheets, knitted bedspreads, etc. .
• the above-mentioned covering articles for beds easily form homes in which organisms such as house dust mites and the like can settle.
• House dust mites for example, feed on fungi and dander on human skin which, as we know, end up in bedding.
• house dust mites of this type and of organisms of the same species causes, in many cases, allergic reactions. In the case of house dust mites, it is the droppings that cause allergic reactions. Therefore, one should exterminate the house dust mite to prevent allergies.
• Fibers inter alia intended for bed covering articles, which are treated with a bactericide and / or a fungicide, as well as methods for the treatment during washing, are known in particular from GB-A-2.248 .774, document US-A-3,691,570, document US-A-4,525,409, document EP-A-0.113.254 and document FR-A-2.015.989 as well as according to the literature, more specifically according to the chapter “Antimicrobial protection” of "Textile progress", tome 22 (1992), n ° 2/3/4 and according to the article “Antimikrobielle Ausrustung von Textilien flir den- Spital Berlin" of "Textileveredlung ", volume 26 (October 1991), n ° 10.
• the house dust mite is an arachnid, that is to say a being which is comparable neither to an insect, nor to a bacterium, nor to a fungus and that, for example products which are developed as insecticide, bactericide or fungicide have little or no effect in this case.
• the subject of the invention is a covering article for beds and the like, by means of which the above-mentioned problem is avoided and eliminated.
• the invention consists of a covering article for beds and the like which has the characteristic that it is provided with a house dust mothproof biocide fixed on the article.
• the house dust moth biocide includes at least one miticide as an active ingredient.
• a commercially available biocide A is used under the name "Amicide 90HP2".
• a product based on a natural extract of chrysanthemum petals, more specifically based on pyrethinoid, will be used in accordance with the invention for the acaricide.
• a further object of the invention is to provide a covering article for beds, in which the abovementioned miticide is applied permanently to the fibers of the covering article so that an active effect can be guaranteed for the life of the fiber, starting from the covering article.
• the anti-mite biocide of house dust, more specifically the acaricide is fixed to the covering article by means of a binder.
• the biocide is fixed to the covering article by means of a binder, the advantage is obtained that the biocide is only released very slowly and that a long-lasting effect is guaranteed. Likewise, the advantage is also obtained of being able to wash the covering article several times or even dozens of times without giving rise to the loss of the activity of the biocide.
• a biocide which exhibits bactericidal, antifungal and acaricidal activity.
• fungi we destroy these fungi so that we exclude a broth culture for mites of house dust.
• bactericidal and acaricide action both at the larva stage and at the adult stage with regard to the house dust mite.
• fungi release spores which in themselves also have a pronounced allergic effect and that by their elimination, it is possible to simultaneously suppress a second source of allergy.
• use is preferably made of 4-chloro-3-methylphenol, 1Orophophenylphenol and glycol ether.
• the above-mentioned binder can be of different types. In this case, one can use a product which is already used for other purposes or a product which is used exclusively for fixing the biocide.
• a binder which consists of an acrylic-based product, more specifically based on perfluorinated acrylic compounds.
• a melamine-formaldehyde resin can also be added to the binder, so that the layer obtained more optimally meets the requirements imposed.
• binder it is also possible to add to the binder, other secondary products such as, for example, products which promote resistance to washing and dry washing.
• the biocide is fixed to the article by means of a binder dried using thermal drying, this thermal drying being able to be carried out both by heating and by lyophilization.
• a covering article which is composed of a substrate and by a composite layer applied to the latter.
• the use of a composite layer of this type in combination with the use of the biocide offers the advantage that a large contact surface is obtained on which the biocide can be fixed by means of the binder.
• the biocide can be mixed with the material of which this coating layer is made so that the material of the coating layer acts as a binder.
• a coating layer one can choose, in cases of this type, from among the materials listed below: a synthetic material waterproof; latex; a mixture of acrylic resins and polyurethane resins; a mixture of acrylic resins.
• these fibers are preferably provided with the aforementioned biocide before making the article.
• the biocide is optimally incorporated into the article.
• the covering article is a knitted article, but it can also be a commercially available article, such as woven or tufted fabrics.
• the invention especially demonstrates its usefulness in the case of a mattress protector and / or of what is called an interlayer skin which can be applied over the sheet and / or of an anti-decubitus skin. which is also designated by the expression anti-decubitus mattress pad and / or a bedspread. Indeed, it is most of the time in these articles and especially in interlayer skins of this type, as well as in anti-decubitus skins, that the population of house dust mites is the highest, at least when no specific measures are taken to control house dust mites.
• the mattress protector is constituted in accordance with the invention, by a skin, of well-defined dimensions, of the aforementioned article formed by a substrate and by a composite layer.
• a skin of well-defined dimensions, of the aforementioned article formed by a substrate and by a composite layer.
• which is provided with '' a biocide as indicated above.
• the invention can be implemented in combination with other kinds of mattress protectors, for example without a composite layer and / or having a base layer based on wool or cotton instead of a synthetic material.
• the articles according to the invention apart from domestic use, have a complementary value when they are used in hospitals, in establishments for the elderly and in hotels thanks to the hygienic aspect. which is related to the invention.
• the invention also relates to a method for making a covering article which consists in pretreating the fibers and fixing these fibers on a substrate so that these fibers form a composite layer, with the particularity that the fibers are also treated with during their pretreatment with a biocide, this biocide being fixed on the fibers by means of a binder.
• the mixture of binder and biocide is sprayed onto the fibers during the carding of the latter.
• the fibers treated with the biocide are kept, after treatment with the above-mentioned mixture, for a determined time in closed receptacles.
• the biocide respectively the binder, has the possibility of optimally adhering to the fibers.
• the back side of the substrate is provided with a biocide by mixing this biocide with a coating material and applying it jointly with the coating material on the back side and / or by applying the biocide to the substrate material before applying the coating layer, primer or coating.
• a biocide by mixing this biocide with a coating material and applying it jointly with the coating material on the back side and / or by applying the biocide to the substrate material before applying the coating layer, primer or coating.

• the fibers are successively subjected to different pretreatments.
• they are represented by blocks 6, 7 and 8.
• the fibers are dyed.
• the fibers 5 are stretched for the first time and possibly mixed with fibers from other reserves. This is what is called "pickering".
• the above steps can be replaced by a supply of fibrous rods, the fibrous rods being cut to obtain fibers of determined lengths.
• the fibers 5 are subjected to an even better drawing by using carding.
• the fibers 5 are treated during carding, preferably they are sprayed, with a mixture 9 of the binder with the biocide.
• the biocide which is a house dust mothproof biocide, is dosed according to a ratio of 0.4 to 0.6% by weight of the total.
• the treated fibers 4 and 5 are then temporarily stored in closed receptacles 10, for example in bags.
• a continuous strip 11 is formed, formed by the substrate 2 and by the composite layer 3.
• a knitting machine 12 is used for this purpose.
• a substrate 2 is knitted from a fed material 13, for example synthetic knitting yarns and, systematically , the above fibers 5 are fixed therein by knitting them.
