Definitions

  • the invention relates to a cover for mattresses and/or pillows, in particular a mattress cover, a protective mattress cover, a pillow cover and/or a protective pillow cover.
  • the cover has a cover material which is at least partially, in particular completely, formed from a spacer fabric.
  • Covers for mattresses and/or pillows (hereinafter also referred to as mattress covers and/or pillowcases) that are generally known from practice are regularly provided for the tight-fitting encasing of a mattress core or pillow core, which has a length and a width on the top and bottom that for example, can be large compared to a height and can form a lying surface for one person and/or a support surface for a person's head.
  • Mattress covers and/or pillowcases usually consist of a fabric area forming the top and a fabric area forming the underside.
  • a closure e.g. B. provided in the form of a zipper.
  • the fabric areas of the top and bottom can be formed by separate fabric panels forming the respective lying surface or bottom, which can optionally be connected to one another by fabric strips forming longitudinal sides and transverse sides. Such fabric strips are usually connected to the fabric panels on the top and bottom by seams, with the seams being able to be covered by an edging tape or piping tape.
  • ventilation strips made of a material that is highly permeable compared to the other cover material are also often used on the long and short sides, since conventional cover materials for a cover usually only have low air permeability and the mattress core or pillow core otherwise is insufficiently ventilated.
  • spacer fabrics are more stretchable than spacer fabrics, which means that a user's comfort can be increased with a cover for mattresses and/or pillows made with spacer fabric, since this can be made soft, elastic and pleasant to the touch.
  • the present disclosure can make it possible to provide an improved cover for mattresses and/or cushions, which is distinguished, for example, by increased breathability, a comfortable and soft lying surface or outside, and cost-efficient processability.
  • the cover has a cover material with at least one upper layer and one lower layer.
  • the upper layer can denote an outer layer and the lower layer can denote an inner layer of the cover fabric.
  • the upper layer and the lower layer are at least partially arranged one above the other.
  • the top and bottom layers can be at least partially stacked on top of each other.
  • At least the upper layer of the cover fabric is also made of a spacer fabric, for example a 3D spacer fabric, with at least one outer side of the upper layer facing away from the lower layer, which can be used, for example, as a lying surface for the user and/or as a support surface for a user’s head can serve, several recesses are formed.
  • the upper layer and/or the lower layer of the upholstery fabric is at least partially formed from a natural fiber.
  • the cover according to the invention therefore uses the advantages of a knitted spacer fabric which, for example, has a spacer structure with stitches, for example at least partially made of knitted monofilament or multifilament spacer threads.
  • the recesses formed on the outside enable increased air circulation, increased breathability and/or increased moisture transport.
  • Natural fibers which can be contained and/or knitted into the spacer fabric, for example, sustainability and/or The ecology of the cover can be increased, for example because the natural fibers can be obtained from renewable raw materials. Natural fibers can also be characterized by increased resilience and/or durability. In addition, natural fibers can result in a pleasant, soft feel for the user. Nutur fibers can also be characterized by increased skin compatibility, breathability and/or odor neutrality. In addition, natural fibers can enable cost-efficient production of the cover.
  • the spacer fabric used for the cover differs in several respects from the spacer fabric regularly used for covers.
  • spacer fabrics are regularly produced on so-called warp knitting machines, while spacer fabrics are usually produced on a knitting machine, with an additional distinction being made between flat and circular knitting machines.
  • stitch are lined up around a warp (hence warp knitting machine). The stitches are lined up vertically. Due to this arrangement of the stitches around a warp, the spacer fabric is stable, rigid, inelastic and inextensible. In contrast, the stitches of a spacer fabric are not strung together around a warp, but the stitches as such can be elastic and stretchable, both horizontally and vertically.
  • a knitted spacer fabric can therefore be characterized in particular by the fact that it is elastic and stretchable both in the horizontal and vertical direction, whereas a knitted spacer fabric is completely inelastic and non-stretchable in comparison.
  • Spacer fabrics are therefore static and rigid fabric structures that have little or no elasticity.
  • a spacer fabric has a rigid, hard and plastic-like feel, whereas a spacer fabric can have a textile or fabric-like and soft feel.
  • fiber ends regularly protrude from a surface of the fabric, resulting in a scratchy and rough feel.
  • spacer fabrics usually have a much softer feel, which is sometimes caused by the increased elastic properties of the spacer fabric and a much finer processing compared to spacer fabrics.
  • the cover is designed as a mattress cover or mattress protective cover, it can have an upper side and/or an underside, which can each be dimensioned as a lying surface for a user. If the cover is designed as a pillow case (or pillow slip cover), it can have an upper side and/or an underside have, which can each be dimensioned as a support surface for a head of a user.
  • the cutouts formed at least on the outside of the upper layer of the cover material are to be strictly distinguished from stitches from which the cover material, the lower layer and/or the upper layer can be formed.
  • the cutouts can be larger than the meshes, for example the cutouts can have a cross-sectional area that can be many times (approximately 5 to 100 times or more) larger than an average cross-sectional area of the meshes of the cover material.
  • the cover material can generally be two-layer, three-layer or multi-layer.
  • the cover material can be manufactured and/or formed entirely from spacer fabric and/or 3D spacer fabric.
  • the upper and lower layers can be connected and/or knitted together at least partially, for example at certain points, with threads from the upper and/or lower layer.
  • connecting threads can be used, which can connect the upper and lower layers.
  • one or more middle layers of the cover material can be connected and/or knitted with the upper and/or the layer.
  • connecting threads can also be used here, which can connect at least two layers of the upholstery fabric, for example the upper layer, the lower layer and/or one or more middle layers.
  • the cover according to the invention can be produced in a simple manner, for example, on a large circular knitting machine working according to the so-called 3-way technique with a high throughput over time and therefore high cost-effectiveness.
  • the natural fiber is animal hair fiber, wool fiber, cotton fiber, hemp fiber, eucalyptus fiber, bamboo fiber, linen fiber, wood fiber, viscose fiber, flax fiber, silk fiber, plant fiber, or a combination thereof.
  • such natural fibers can be characterized by increased sustainability, odor neutrality, skin compatibility, durability and/or robustness.
  • the upper layer, the lower layer and/or one or more middle layers of the upholstery fabric have a proportion by weight of natural fibers, based approximately on the respective layer or the entire upholstery fabric, of 2% to 99%, for example at least 5% 10%, at least 15%, at least 20% and/or at least 25%. At least 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, or 75% of natural fibers is also conceivable.
  • the proportion, for example the proportion by weight and/or the proportion by volume, of natural fibers, for example in relation to the respective layer or the entire cover fabric, in the upper layer is greater than the proportion, for example the proportion by weight and/or the proportion by volume, of Natural fibers in the bottom and/or one or more middle layers.
  • the proportion in the upper layer can be at least twice as large as the corresponding proportion of natural fibers in the lower and/or one or more middle layers.
  • the upper layer consists essentially and/or almost completely, for example completely, of natural fibers and the lower layer and optionally one or more middle layers consist essentially and/or almost completely, for example completely, of synthetic fibers.
  • the recesses can be designed to be open to the outside, i.e. in the direction of the user, and/or have a cross section that is open to the outside.
  • the recesses can thus denote openings.
  • the recesses can generally be advantageous with regard to the exchange of air and the removal of moisture as well as the compensation of temperature fluctuations.
  • the recesses can also provide increased elasticity, which offers a user a soft feel and can also allow the cover to be optimally adapted to the user or head lying on it, without this being caused by brittle spacer threads that are often noticeable with spacer fabrics would be affected.
  • the recesses formed at least on the outside of the upper layer can also provide and/or form a mesh structure of the cover material.
