Definitions

• the invention relates to a washable cover for mattresses or the like of textile material containing one Water vapor permeable, allergen and waterproof Barrier layer and an upper material as well as a mattress with such a washable cover.
• the object of the present invention is to provide a reference for Mattresses and a mattress with such a cover the to provide the type mentioned at the beginning, by means of which not only effective protection against allergens but also a high lying comfort is given.
• This task is with a washable cover for mattresses or the like of textile material containing one Water vapor permeable, allergen and waterproof Barrier layer and an upper material, solved in that the Cover at least one other fabric and one bulky, at least 3 mm thick cotton fleece contains that Cotton fleece between the upper and the other textile Fabric is arranged that the upper, the Cotton fleece and the other textile fabrics at least are connected at points by threads, and that the Barrier layer on the further textile fabric its connection with the upper material and the cotton fleece is laminated on at least at certain points.
• the cotton fleece and the other textile fabrics connected by threads and then only the barrier layer on the textile Laminated fabrics will damage the Water resistance of the barrier layer effectively avoided and nevertheless the textile reinforcement of the barrier layer (membrane or foil) over the further textile fabric ensured.
• the upper part, the Cotton fleece and the other textile fabric connecting Threads a shifting of the cotton fleece and thus a lump of the cotton fleece effectively prevented.
• the Sewing with lines arranged in a line has been the case here especially proven.
• the appearance of the invention washable covers and the resistance to displacement of the cotton fleece can be improved if the cotton fleece and the other textile fabrics sewn together with seams are a pattern in the form of rectangles, squares, rhombuses or the like.
• the lying comfort of the washable cover can be increased in particular if the cotton fleece has a thickness between 3 and 40 mm, preferably between 5 and 25 mm and a basis weight between 100 and 500 g / m 2 , preferably between 200 and 400 g / m 2 .
• the barrier layer has a water vapor permeability of at least 800 g / m 2 24 hours.
• the water vapor permeability is determined in accordance with ASTM E96-66 (Procedure B), however, 30 ° C is chosen as the water temperature and a temperature of 30 ° C and a relative humidity of 60% for the air climate.
• the barrier layer has a water vapor permeability of 1000 to 8000 g / m 2 24h, in particular of 1000 to 5000 g / m 2 24h.
• the top, the bottom and the orbiting web at least the face material that Cotton fleece, the other textile fabrics and the Barrier layer included. It goes without saying that the orbiting path in the direction of its length from several pieces is composed, it being particularly expedient that to assemble the orbital path from pieces that are in their Length of the length of the top and bottom Correspond to circumferential lines.
• the sections of the circulating orbit can with each other and with the top and bottom can be easily sewn together if this for example in the form of an outwardly projecting bead takes place, the on the inside of this bead Barrier layer of adjacent parts tightly over the seam be pressed together so that no moisture over them Seams can penetrate to the mattress core. It also increases Sewing to such a bead the dimensional stability of the cover according to the invention and the aesthetic appearance.
• a washable cover is particularly preferred, in which the Top and bottom connecting web of two circumferential Paths is formed, preferably with one another Zipper are designed to be connectable. It is recommended here itself, especially if the zippers are not tight enough are used so that the two lanes on the Overlap the side facing the mattress core. These overlaps can also be done by an additional circulating path (Zipper cover).
• the washable cover according to the invention has Particularly proven when the other textile fabric is a Knitted fabric with one stitch side and one stitch foot side, and that the mesh base side faces the barrier layer is arranged. It is also an advantage if the Barrier layer has a reversible stretch, at least is the same size as the reversible elongation of the further textile fabric, nm the risk of injury Minimize barrier layer.
• the object of the invention is also achieved by a mattress that has a washable cover according to the invention having. It has proven particularly useful here if the washable cover smooth on the surface of the mattress core is present.
• the upper material also called drell
• fabrics or terry goods made from threads made of natural fibers, synthetic polymers or mixtures thereof In the case of synthetic polymers, polymers made of polyester have proven to be particularly favorable.
• fabrics with a basis weight of 150 to 400 g / m 2 for terry fabrics those with a basis weight of 80 to 300 g / m 2 are regarded as particularly suitable.
• the upper material should be flame retardant according to DIN 54336.
• the fiber fineness of the short and / or continuous fibers forming the cotton fleece should preferably be between 3.3 and 17 dtex, the basis weight between 100 and 500 g / m 2 , preferably between 200 and 400 g / m 2 , for example 300 g / m 2 and the Thickness between 3 and 40, in particular 5 and 25 mm.
• the cotton fleece can be consolidated by needles.
• solidification via thermal or chemical bonding of the fibers to one another at their crossing points is favorable. In the case of chemical bonding, it must be ensured that the chemical products used are harmless to the user with regard to allergic and toxic reactions.
• Acrylic resins have proven themselves particularly well for the consolidation of the cotton fleece. Polyester fibers have proven particularly useful.
• Membranes such as are particularly suitable for the barrier layer they are described in WO 94/19178 and EP 0 622 488 A1. Membranes such as those under the brand name DURETA® are well proven. A Thickness between 10 and 30 microns, for example 15 microns has for these membranes turned out to be particularly favorable. Especially It is favorable if the barrier layer is tight against Particles with dimensions larger than 10 nm, preferably larger 1 nm. Such references are surprisingly dense against unpleasant smells that arise in the mattress core can.
• the composite formed from the upper material, cotton fleece and other textile fabrics should be formed from such materials that the composite has a water vapor permeability between 1500 and 4000 g / m 2 24 hours. Water vapor permeabilities in the range from 2300 to 3000 g / m 2 24h, in particular from 2650 to 2700 g / m 2 24h, have proven their worth. A thickness of the finished composite in the range of 6 to 16 mm if the upper material is made of a woven fabric and in the range of 7 to 20 mm if the upper material is made of terry cloth has been found to be sufficient for most requirements regarding lying comfort exposed.
• a fabric with multifilament threads made of polyester and a weight per unit area of 216 g / m 2 is used as the upper material.
• the cotton fleece consisted of short polyester fibers and was spray-bonded with acrylic resin as a cross-ply fleece, had a weight per unit area of 300 g / m 2 and a thickness of 12 mm.
• a knitted fabric made of textured polyester filaments with a basis weight of 40 g / m 2 was used as a further textile fabric. Fabric, cotton fleece and knitted fabric were quilted together in such a way that the quilting seams formed a diamond pattern. The resulting composite had a water vapor permeability of 2650 g / m 2 24h.
• a 15 ⁇ m thick membrane made of polyetherester (Dureta ®) was laminated onto the mesh foot side of the knitted fabric, which was arranged away from the cotton fleece, using grid-shaped adhesive dots. Before it was laminated, the membrane had a water vapor permeability of approximately 3000 g / m 2 for 24 hours.
• the resulting composite material had a water vapor permeability of 1300 g / m 2 24h and was water and allergen-proof. After using it as a mattress cover, the material composite could be made largely allergen-free by simply washing it at 60 ° C. The cover was rated by the user as pleasant in terms of climate and lying comfort.
• a terry cloth made of textured polyester multifilament threads was chosen as the upper material. It had a weight per unit area of 130 g / m 2 .
• the bats described in Example 1 were used for cotton fleece, further textile fabrics and membranes. The outer material, cotton fleece and other textile fabrics were quilted by parallel longitudinal seams, after which the material composite had a water vapor permeability of 2700 g / m 2 24 hours. After the membrane had been laminated on point by point, the resulting composite material had a water vapor permeability of 1500 g / m 2 for 24 hours.
• a cover made of this material composite was also rated as pleasant by the users in terms of climate and lying comfort. After using the cover around a mattress, the material composite could be made largely allergen-free by simply washing it at 60 ° C.
