Definitions

  • the invention relates to a cover for mattresses or the like, containing one water vapor permeable, allergen and waterproof barrier layer as well as a Mattress with such a cover.
  • the shell of the The mattress must then be removed from the mattress at regular intervals and be washed to remove the secretions of the human body, which are also form a breeding ground for allergens, also to remove from the shell.
  • the object of the present invention is to provide a cover for mattresses and To provide a mattress with such a cover, through which not only one effective protection against allergens, but also a reduced tendency to rustle Envelope is given.
  • This object is achieved in a case for mattresses or the like, containing a water vapor permeable, allergen and waterproof barrier layer, in that the barrier layer has a working capacity of 150 to 400 MJ / m 2 and at least predominantly of a film or membrane with a thickness of 5 to 40 microns.
  • the force-strain curve is plotted in a right-angled coordinate system, with the force (F) being plotted upwards and the strain (L) plotted to the right. 1 shows an example of such a KD curve.
  • the tensile strength test is generally continued until the material to be tested breaks, the maximum force that occurs is called the breaking force, the associated change in length is called the elongation at break.
  • the tensile work of a material is the work in the tensile test until a certain tensile force is reached or its associated change in length in the physical sense (as the path integral of the force, in Fig. 1, i.e. the area OFDO) and can thus be derived from a KD curve be determined.
  • Of interest for the present invention is the pulling work that must be done until the tearing force is reached. This pulling work (area OF max BO) is called work capacity and is characteristic of the material to be tested.
  • the determination of the force-elongation curve and the derivation of the physically relevant quantities is known to the person skilled in the art and is carried out in accordance with DIN 53857.
  • the working capacity obtained according to the above-described method is from 150 to 400 MJ / m 2 , preferably from 200 to 250 MJ / m 2 , and which have a thickness of 5 to 40 microns. It has proven to be advantageous if the flexible film or membrane of the barrier layer has a thickness of approximately 5 to approximately 14 ⁇ m.
  • the cover can be used as a support for the mattress, for example as a bed sheet replacement. It is favorable for the anti-allergenic effect of the barrier layer if the barrier layer is sealed against particles which have dimensions greater than 10 nm, preferably greater than 1 nm. This ensures that even flakes of skin, which can have a size of well below 1 ⁇ m and are secreted by the user of the mattress in an amount of 0.5 g in 8 hours, cannot penetrate into the mattress core.
  • the use of at least predominantly non-porous foils or membranes has proven successful.
  • Non-porous, waterproof, water vapor-permeable membranes have proven to be particularly advantageous, which are characterized in that the membrane consists of a material which contains a polymer based on, for example, copolyetherester or copolyetheramide.
  • Such membranes are available on the market, for example, under the brand names SYMPATEX or DURETA.
  • a water vapor permeability of the barrier layer of at least 800 g / m 2 is desirable for 24 hours.
  • the water vapor permeability is determined in accordance with ASTM E96-66 (Procedure B), although 30 ° C is chosen as the water temperature and a temperature of 30 ° C and a relative air humidity of 60% for the air climate.
  • mattresses containing a mattress core and a cover made of the films and membranes according to the invention can be used directly.
  • a cover could, for example, be glued to the mattress core at least at certain points in order to avoid displacement of the cover on the mattress, or else around the mattress core in the form of a encasings ".
  • the cover contains a textile fabric as the outer material in addition to the barrier layer. Suitable materials for this are 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. For fabrics with a basis weight of 150 to 400 g / m2, for terry fabrics those with a basis weight of 80 to 300 g / m2 are considered particularly suitable.
  • the upper material should be flame retardant according to DIN 54336.
  • Barrier layer and upper material are usually in the form of laminates used, the membranes or films often only in places with them reinforcing textile fabrics are laminated together in order to maintain high water vapor permeability.
  • the upper material often forms at the same time the mattress surface.
  • a cotton fleece between the barrier layer consisting of the films or membranes according to the invention and the upper material.
  • This cotton fleece should be fluffy and at least 3 mm thick, preferably between 3 and 40 mm, in particular between 5 and 25 mm.
  • voluminous fleeces are recommended that have good structural elasticity and high resilience, even after prolonged use.
  • the covers can also be effectively cleaned by simple vacuuming, for example using a commercially available vacuum cleaner.
  • a cleaning can remove, for example, mite carcasses and common allergens from the shell to the barrier layer without the shell having to be removed from the core, for example for washing.
  • the cotton fleece at least predominantly from long fibers of about 30 to about 200 mm, is preferred about 80 to 150 mm in length, the individual titer of which is between about 3 and 20 dtex.
  • the long fibers should advantageously consist predominantly of synthetic fibers selected from the group of polyester, polyacrylic, nylon or mixtures thereof.
  • synthetic fibers selected from the group of polyester, polyacrylic, nylon or mixtures thereof.
  • the solidification can be done by needles. However, it is more favorable to solidify them by thermal or chemical bonding of the fibers to one another at their crossing points. 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. Spreading and subsequent melting of synthetic adhesives based on polyamide or polyester has proven particularly useful.
  • a mixture with bicomponent fibers is suitable for the thermal bond, e.g. Trevira 254 or Grilene K 150.
  • These bicomponent fibers from Core-sheath types are used in the fiber sheath at appropriate furnace temperatures melted without the core losing the fiber structure. The melting one
  • the cladding layer leads to a bond with the other fibers and thereby a mechanically stable cotton structure. It is beneficial if the admixture is on Bicomponent fibers approximately between 20 and 70%, preferably between 35 and 55 %, based on the total weight of the fleece.
  • the bonding of the cotton fleece can also be done by the Adding binder fibers can be achieved, a consolidation technique that is Known expert.
  • the casing according to the invention it has proven useful if it a top, a bottom, and the top and bottom at their ends connecting lines (border). It is advantageous if the top that Underside and the webs connecting the top and bottom at their ends contain at least the upper material, the wadding and the barrier layer. A such cover can then over the top and bottom and the narrow Flanks of a mattress.
  • the mattress core ventilation and - Venting is solved by air filtering for the long flanks Textile inserts are used.
  • the textile inserts are connected to the cover for example by gluing, sewing or hot band sealing.
  • the task of the filtering textile inserts is to fix the edges of the cover as well as the coarser mattress core abrasion. Coming as material for it dense textiles made of natural or chemical fibers or their mixtures.
  • the cover according to the invention also designed as a removable cover, it may be necessary to another, porous textile fabric between the barrier layer and the Bring cotton fleece.
  • the upper material, the cotton fleece and the further textile fabric at least at points are connected by threads, and that the barrier layer on the other Textile fabrics after its connection with the upper and the Cotton fleece is laminated on at least at certain points.
  • the case be one between the Top and bottom circumferential web has the top and bottom connects with each other.
  • top, bottom and orbiting should at least the upper material, the cotton fleece, the other textile fabric and contain the barrier layer. It is to enable the cover to be removed favorable if the web connecting the top and bottom consists of two circumferential ones Paths is formed, which can be connected to one another, preferably via a Zipper, are formed.
  • the zipper also ensures that Mattress core ventilation and ventilation.
  • the appearance of the sleeves according to the invention and the resistance to displacement of the Cotton fleece can be improved in that the cotton fleece with the Upper material or with the upper material and / or the further textile Fabric is sewn by seams, which is a pattern in the form of rectangles, Form squares, rhombuses or the like. It is important to ensure that the Foil or membrane is only laminated after the sewing process, so your Water tightness is maintained.
  • the object of the invention is also achieved by a mattress that has a shell with the barrier layer according to the invention.
  • a mattress that has a shell with the barrier layer according to the invention.
  • the cover is smooth on the surface of the mattress core is present.
