[0004] Textile for a cover, especially for a duvet and / or a mattress
[0005] Reference to related applications
[0006] The present application claims priority over German utility model application No. 202025 102 059.9, filed on 15 April 2025, which is incorporated in full by reference into this document.
[0007] Technical field
[0008] The invention relates to a textile for a cover, in particular for duvets and / or mattresses. The textile comprises a fabric which is at least partially, and in particular completely, formed from a spacer fabric with bioceramic particles.
[0009] Technical background
[0010] Commonly known in practice, covers for blankets, hereinafter also called duvet covers, or mattresses, hereinafter also called mattress covers, are regularly intended for the close-fitting encasing of a duvet or mattress core, which has a length and a width on the top and bottom that may be large compared to a height, for example, in order to form a covering surface and / or a support surface for a person.
[0011] Duvet covers and / or mattress covers typically consist of a top layer and a bottom layer. Removable covers, which allow the duvet or mattress core to be inserted or removed, usually have a closure, such as a zipper. Clothing items are typically made by sewing together several pieces of fabric to create the desired garment, such as trousers, leggings, a blouse, pajamas, underwear, a bra, panties, briefs, and / or a towel.
[0012] Depending on the design of the cover, the fabric areas of the top and bottom can be formed by separate layers of fabric, each forming the respective covering surface and / or lying surface or underside, which can optionally be connected to each other by strips of fabric forming the longitudinal sides and the transverse sides. Such fabric strips are usually attached to the fabric panels of the top and bottom by seams, whereby the seams can be covered by a binding tape or a piping tape.
[0013] In the case of covers known from practice, especially mattress covers, ventilation strips made of a highly permeable material compared to the rest of the cover fabric are often used on the long and short sides, since usual fabrics or cover fabrics for a cover usually only have low air permeability and the blanket or mattress core would otherwise be insufficiently ventilated.
[0014] For example, German patent DE 202012 005 880 U1 discloses a two-part design for a mattress cover, with one side consisting of a viscoelastic foam for winter use and the other side of a spacer fabric (also called 3D spacer fabric) for summer use. The latter, due to its higher breathability, creates a better microclimate for the sleeper. However, a disadvantage of this design is that spacer fabrics are relatively rigid and difficult to bend, which limits the sleeper's comfort.
[0015] Summary
[0016] Spacer fabrics are more elastic than spacer knits due to their different structural design, which generally allows for increased comfort for the user of a textile made with spacer fabric, for example a cover for blankets and / or mattresses or a garment, as these can be made soft, elastic and with a pleasant feel.
[0017] In practice, however, it has been shown that with the known spacer fabrics, especially when used as covers for blankets and / or mattresses, but also when used as clothing, there is a need for improvement with regard to breathability and comfort.
[0018] Furthermore, well-known textiles for blankets, clothing, and / or mattresses are often made almost exclusively from synthetic fibers. This can have ecological disadvantages and can also reduce user comfort, for example, because synthetic fibers can feel relatively cold.
[0019] The present disclosure can, in particular, enable the provision of an improved textile for covers, especially for duvet covers and / or mattresses, which is characterized, for example, by increased breathability, improved temperature regulation, a comfortable and soft covering surface and / or sleeping surface or outer surface, as well as cost-effective processing. The improved textile for covers can also be used for seats as seat covers and / or for cushions as cushion covers and / or for garments, or can form seat covers and / or cushion covers and / or garments, thus providing improved seat covers and / or cushion covers and / or garments. All the aforementioned and subsequent advantages and characteristics of the textile for a cover also apply to the textile for a garment and / or for a seat cover and / or for a cushion cover.In other words, the textile according to the invention can also be a textile or fabric for clothing.
[0020] This is made possible, among other things, by the independent claims. Further embodiments are specified in the dependent claims and the following description.
[0021] One aspect of this disclosure relates to a textile for a cover for a comforter, for example, a duvet or comforter cover, for a mattress, for example, a mattress cover, and / or a cover for a seat, a cushion, a sofa, a couch, an upholstered piece of furniture, a chair, a piece of seating furniture, or the like. Alternatively or additionally, this disclosure may relate to a cover for a comforter, a duvet cover, a comforter cover, a mattress topper, a mattress cover, a seat cover, and / or a cover for a seat, a cushion, a sofa, a couch, an upholstered piece of furniture, a chair, a piece of seating furniture, or the like. All disclosures relating to the textile for a cover apply equally to all items described herein for which the cover can be used.
[0022] The textile comprises a fabric with at least one upper layer and one lower layer. The upper layer can be an outer layer, and the lower layer can be an inner layer of the fabric. The upper and lower layers are at least partially arranged one above the other. For example, the upper and lower layers can be at least partially stacked on top of each other. At least the upper layer of the fabric, or the entire fabric, or at least part of the fabric, is furthermore formed from a spacer fabric, for example, a 3D spacer fabric, wherein the spacer fabric comprises fibers with bioceramic particles. Furthermore, at least one of the outer surfaces of the upper layer, facing away from the lower layer and serving, for example, as a covering or lying surface for the user, has several cutouts.Alternatively or additionally, at least on one of the outer sides of the lower layer facing away from the upper layer, several recesses can be formed.
[0023] Optionally, the outer surface of the top layer comprises a fine-knit structure, which can be made of viscose, lyocell, fibers with bioceramic particles, and / or any mixture thereof. Furthermore, the top layer and / or the bottom layer of the cover fabric can be made at least partially of a natural fiber.
[0024] Additionally or alternatively, the textile for a cover can have a fine knit structure on at least one outer side of the lower layer facing away from the upper layer, which can be made in particular of viscose, lyocell, fibers with bioceramic particles and / or any mixture thereof.
[0025] The textile according to the invention, in particular as a cover, thus utilizes the advantages of a spacer fabric, which, for example, has a spacer structure with stitches, at least partially made of knitted mono- or multifilament spacer threads.
[0026] Furthermore, the cutouts formed on one or both outer sides allow for increased air circulation, increased breathability and / or increased moisture transport.
[0027] Furthermore, the use of materials such as viscose, lyocell, or other cellulose-based or regenerated fibers in the fine-knit structure on the outer surface of the textile can create a particularly cozy and soft feel for the user. The modifiable fiber geometry of viscose and lyocell fibers allows for application-specific optimization of properties for the user. For example, hollow viscose fibers can be used, which are softer and offer improved thermal insulation. The reduced heat loss, combined with the high softness of the fibers, creates a particularly cozy and warm tactile sensation for the user of the duvet cover and / or mattress cover. Additionally, hollow viscose fibers, for example, offer high absorption and retention of liquids, thus improving the skin climate for the user.Due to their high absorption capacity, these fibers can, for example, absorb perspiration, which is then released into the surrounding air, thus helping to cool and dry the skin. Furthermore, the large, air-filled cavities of these dry hollow fibers provide excellent insulation for the wearer. In other words, cellulose-based viscose and lyocell fibers are characterized by their high breathability and exceptionally soft surface feel. These fibers can also be sustainable and biodegradable. In addition to viscose and lyocell, regenerated fibers or other cellulose-based fibers, such as modal and cupro fibers, can also be used in fine-knit structures, forming at least part or even the entire fabric.It is also possible to combine several fibers and use them in the fine knit structure, for example viscose and lyocell with fibers containing bioceramic particles, or in particular viscose fibers with bioceramic particles and / or lyocell fibers with bioceramic particles.
[0028] Furthermore, the use of natural fibers, which can be incorporated into and / or woven into the spacer fabric, can increase the sustainability and / or ecological impact of the cover, as natural fibers, like regenerated fibers, viscose, and / or lyocell, can be derived from renewable resources. Examples of suitable natural fibers include animal hair, wool, cotton, hemp, eucalyptus, bamboo, linen, wood, flax, silk, plant fibers, or a combination thereof. Natural fibers can also be characterized by increased resilience and / or durability. In addition, natural fibers can provide a pleasant, soft feel for the user. Furthermore, natural fibers can be distinguished by improved skin compatibility, breathability, and / or odor neutrality.Furthermore, natural fibers can enable cost-efficient production of the cover.
[0029] The spacer fabric used for upholstery differs in several ways from the spacer fabrics regularly used for upholstery. For example, spacer fabrics are typically produced on warp knitting machines, while spacer fabrics are usually produced on a knitting machine, with a further distinction made between flat and circular knitting machines. In the production of a spacer fabric, stitches are arranged around a warp (hence the name warp knitting machine). The stitches are arranged vertically. Because of this arrangement of the stitches around a warp, the spacer fabric is stable, rigid, inelastic, and non-stretchable. In contrast, the stitches of a spacer fabric are not arranged around a warp; rather, the stitches themselves can be elastic and stretchable, both horizontally and vertically.In contrast to a spacer fabric, a spacer knit is characterized by its elasticity and stretchability in both horizontal and vertical directions, whereas a spacer knit is completely inelastic and non-stretchable. Spacer knits are therefore static and rigid fabric structures with little to no elasticity. Furthermore, a spacer knit has a rigid, hard, and plastic-like feel, while a spacer knit can have a textile-like or fabric-like and soft feel. Additionally, fiber ends regularly protrude from the surface of a spacer knit, resulting in a scratchy and rough texture.In contrast, spacer knits generally have a much softer feel, which is partly due to the increased elastic properties of the spacer knit and a much finer workmanship compared to spacer woven fabrics.
[0030] Furthermore, the use of fibers with bioceramic particles in the spacer fabric also enables optimized temperature regulation. Bioceramic particles are particles that exhibit high biocompatibility. In other words, bioceramic particles themselves have no negative impact on living organisms. The terms "bioceramic" and "bioceramic particles" can therefore be used synonymously with "biocompatible ceramic" and "biocompatible ceramic particles," respectively. Biocompatible ceramics for this application are biocompatible oxide ceramics, such as aluminum oxide, silicon oxide, zirconium dioxide, titanium oxide, magnesium oxide, zinc oxide, aluminum titanate, and / or barium titanate. Some bioceramics, particularly aluminum oxide, silicon oxide, titanium oxide, magnesium oxide, and / or zinc oxide, are characterized by their high reflectivity of electromagnetic radiation with a wavelength of 10 pm to 1 mm.Electromagnetic radiation with a wavelength of 10 pm to 1 mm is also known as far infrared (FIR), FIR radiation, thermal radiation, or far infrared radiation. This means that the reflectivity, the ratio between reflected and incident radiation, is very high. Therefore, a large portion, if not all, of the far infrared radiation incident on a bioceramic is reflected. In addition to the strong reflection of FIR, electromagnetic radiation with a wavelength of 280 nm to 380 nm, the so-called ultraviolet radiation (UV radiation), or UV-A radiation (for the wavelength range of 315 nm to 380 nm) and UV-B radiation (for the wavelength range of 280 nm to 315 nm), is absorbed by bioceramic particles.This means that no or only a negligible amount of UV radiation is transmitted, i.e., allowed to pass through the fiber with bioceramic particles.
[0031] Fibers with bioceramic particles are therefore fibers comprising one or more oxide ceramics, wherein the oxide ceramics are processed into particles in the nanometer size range, for example, in the range of 1 nm to 1000 nm, particularly in the range of 10 nm to 900 nm, for example, in the range of 50 nm to 300 nm, optionally in the range of 100 nm to 280 nm, and are then permanently, and in particular wash-resistant, bonded to the fiber. The fibers with bioceramic particles can contain bioceramic particles comprising only one oxide ceramic or several oxide ceramics. Particularly preferred oxide ceramics include, for example, aluminum oxide, silicon oxide, titanium oxide, magnesium oxide, and / or zinc oxide.
[0032] Simultaneously, the fibers can be natural, synthetic, or regenerated. In other words, the bioceramic particles can be permanently incorporated into natural, synthetic, and / or regenerated fibers. Fibers with bioceramic particles can, in principle, be natural fibers with bioceramic particles, synthetic fibers with bioceramic particles, and / or regenerated fibers with bioceramic particles. For example, natural fibers such as cotton can be processed in such a way that the bioceramic particles are permanently bonded to the natural fiber. This is made possible, in particular, by processes specifically adapted to bioceramics. For instance, the bioceramic particles are dispersed in a solution, the cotton is soaked in this solution, and then specially thermally treated so that a uniform and permanently adhering coating of bioceramic particles is created on the surface of the cotton fiber.In contrast, with synthetic and regenerated fibers, it is possible, for example, to add bioceramic particles to the fiber base materials, such as polyester or cellulose, during the manufacturing process, thus obtaining fibers containing bioceramic particles. These bioceramic particles are preferably arranged mostly or entirely on the surface of the fiber and not within it. This surface arrangement ensures that thermal radiation is not absorbed by the fibers but reflected beforehand, resulting in little or no heat input into the fiber. Consequently, fibers can be produced, for example, by mass, with a bioceramic particle content of 10% to 100%, and in particular, 20% to 50%, for example, 30%. In other words, it is also possible to produce pure bioceramic fibers.Ultimately, fibers containing bioceramic particles can be used to produce filaments or yarns, which, upon further processing, can form, for example, spacer fabrics or fine-knit structures, either completely or partially. Thus, viscose fibers with bioceramic particles and / or lyocell fibers with bioceramic particles can be used in fine-knit structures, combining the advantages of bioceramics with those of viscose or lyocell, or other cellulose-based or regenerated fibers.
[0033] Furthermore, the fibers containing bioceramic particles can have a diameter in the micrometer range, for example, from 5 pm to 50 pm, particularly from 5 pm to 30 pm, for example, 10 pm, but always greater than 3 pm. At the same time, the length of the fibers containing bioceramic particles can exceed 250 pm. This prevents the fibers from penetrating the lower respiratory tract. In other words, the fibers containing bioceramic particles cannot pass through the bronchioles or alveoli. Because the fibers with biocompatible particles do not interact, or only minimally interact, with the human immune system, and because at least the bioceramic particles cannot be biodegraded, it is particularly advantageous that, due to their size, the fibers containing bioceramic particles cannot unintentionally accumulate in the body, for example, through inhalation.At the same time, fibers containing bioceramic particles primarily break perpendicular to a longitudinal axis, and longitudinal splitting is therefore negligible. As a result, even when fibers containing bioceramic particles break, no respirable fiber dust is produced. The properties of these fibers protect users of a cover containing bioceramic particles from unwanted fiber accumulation in the lungs through inhalation.
[0034] Furthermore, fibers with bioceramic particles are characterized by exceptional durability at a low mass and protection against selected non-ionizing electromagnetic radiation. In other words, fibers with bioceramics are durable, lightweight, absorb UV rays, and reflect far-infrared radiation. These properties are direct effects of the bioceramic particles. Because the bioceramic particles are biocompatible and do not interact, or only minimally interact, with biological material—in other words, they are bioinert—the fibers are particularly resistant and wear-resistant. At the same time, the hard and robust nanometer-sized oxide ceramic particles ensure that the entire fiber is exceptionally stable, while the fiber's mass is not significantly increased by the bioceramic nanoparticles.Although ceramics generally possess great hardness and brittleness, and are therefore not plastically deformable, the combination of biocompatible oxide ceramic with the easily deformable fiber makes it possible to obtain a resilient fiber. The use of pure bioceramic fibers in a spacer fabric also results in a flexible and resilient spacer fabric due to the interaction with other fibers that are not solely composed of bioceramics. In other words, the choice and ratio of the various fibers used can influence the elasticity and softness of the textile.
[0035] Furthermore, the absorption capacity of UV-A and UV-B radiation, as well as the reflection capacity of FIR, are directly attributable to the bioceramic particles incorporated into the fibers, thus enabling optimized or improved temperature regulation. The combination of bioceramic particles and a fiber allows UV rays to be absorbed by the bioceramic particles, thereby providing protection against UV radiation. Simultaneously, FIR is reflected by the bioceramic particles. This results in little or no additional heat radiation, such as the thermal back radiation from the atmosphere, passing through a fiber containing bioceramic particles. Consequently, no heat radiation is stored in the fibers containing bioceramic particles. A user of a cover containing bioceramic particles is therefore protected from excessive heat, resulting in a feeling of freshness.
[0036] On the other hand, thermal radiation emitted by a person, for example, is also reflected back and reabsorbed. Far-infrared radiation essentially corresponds to the radiation emitted by an idealized blackbody radiator with a temperature of up to approximately 350 K at its maximum spectral energy density. Bioceramic particles reflect up to 100% of this far-infrared radiation. Consequently, every object emits far-infrared radiation at approximately room temperature. To illustrate, this means that, to a good approximation, the thermal radiation emitted by a living person is completely reflected by fibers containing bioceramic particles. This reflected thermal radiation is then reabsorbed by the body. In other words, heat loss is partially or completely prevented. The fibers containing bioceramic particles provide excellent thermal insulation, protecting against the cold.The absorbed heat radiation improves microcirculation and blood flow in the tissue, as well as promoting muscle relaxation. Users of the cover with bioceramic fibers experience a particularly warm and relaxing sensation.
[0037] The advantages of a fiber with bioceramic particles can be combined with the advantages and properties of a spacer fabric, optionally also a fine-knit structure, in particular made of viscose and / or lyocell, to create a textile according to the invention.
[0038] If the textile is designed for a cover as a duvet cover or mattress cover, it can have a top and / or a bottom, each of which can be dimensioned as a covering surface or lying surface for a user.
[0039] The cutouts formed at least on the outer surface of the upper layer and / or the outer surface of the lower layer of the fabric must be strictly distinguished, in the context of this disclosure, from the meshes from which the fabric, the lower layer, and / or the upper layer may be formed. Compared to the meshes, the cutouts may be larger; for example, the cutouts may have a cross-sectional area that is many times (approximately 5 to 100 times or more) larger than the average cross-sectional area of the meshes of the covering fabric.
[0040] The fabric and / or textile can generally be two-layered, three-layered, or multi-layered. In particular, the fabric and / or textile can be made entirely or at least partially from spacer fabric and / or 3D spacer fabric and / or from spacer fabric or 3D spacer fabric with bioceramic particles.
[0041] In a two-layered fabric, the upper and lower layers can be at least partially connected and / or intertwined with threads from the upper and / or lower layer, for example, at specific points. Alternatively or additionally, connecting threads can be used to join the upper and lower layers. In a three- or more-layered fabric, one or more middle layers can be connected and / or intertwined with the upper and / or lower layer. Alternatively or additionally, connecting threads can also be used here, which can join at least two layers of the fabric, such as the upper and lower layers and / or one or more middle layers.
[0042] The textile according to the invention for a cover can be produced in a simple manner, for example on a large circular knitting machine operating according to the so-called 3-way technique, with high throughput and therefore high economic efficiency.
[0043] According to one embodiment, the natural fiber is an animal hair fiber, a wool fiber, a cotton fiber, a eucalyptus fiber, a bamboo fiber, a linen fiber, a wood fiber, a flax fiber, a hemp fiber, a silk fiber, a plant fiber, or a combination thereof. Such natural fibers can be distinguished, compared to synthetic fibers, by increased sustainability, odor neutrality, skin compatibility, durability, and / or robustness.
[0044] According to one embodiment, the top layer, the bottom layer, and / or one or more middle layers of the fabric have a weight percentage of natural fibers, based on the respective layer or the entire fabric, of 2% to 90%, for example, at least 5%, at least 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 are also conceivable.
[0045] The cutouts can be open to the outside, e.g., towards the user or in the opposite direction, and / or have an outwardly open cross-section. The cutouts can thus be considered openings. These cutouts can generally be advantageous with regard to air exchange, moisture transport, and the compensation of temperature fluctuations. They can also provide increased elasticity, offering a soft feel to the user and allowing the textile to adapt optimally to the user without the discomfort often caused by brittle spacer threads found in spacer fabrics.
[0046] The cutouts, formed at least on the outer surface of the top layer and / or the outer surface of the bottom layer, can further provide and / or create a mesh structure in the fabric. In other words, the fabric can have a mesh structure, such as a honeycomb-like mesh structure, with the cutouts, at least on the outer surface. The cutouts of the mesh structure and / or the fabric can, for example, be arranged in a regular pattern on the outer surface of the fabric. In other words, the cutouts can be arranged regularly and / or in a regular pattern. However, an irregular arrangement, for example, one forming a pattern, is also conceivable.
[0047] The recesses, such as those open to the outside, can vary in their geometry, for example being round, square, oval, polygonal, elliptical or any other shape with regard to their open cross-section.
[0048] For example, the recesses can be honeycomb-shaped. Alternatively or additionally, the recesses can have a round, rounded, square, rectangular, polygonal, triangular, elliptical, oval and / or polygonal cross-section.
[0049] According to one embodiment, the upper and / or lower layer of the fabric is at least partially made of textured, twisted yarn, in particular multifilament yarn and / or yarn with bioceramic particles. This provides a soft and pleasant feel with optimal temperature regulation.
[0050] According to one embodiment, the upper and / or lower layer of the fabric is at least partially made of monofilament yarn, in particular polyester yarn, smooth polyester yarn, polyethylene yarn, smooth polyethylene yarn, polyamide yarn, smooth polyamide yarn, and / or one of the aforementioned yarns with bioceramic particles. If the fabric is made of monofilament yarn on the underside facing the duvet and / or mattress, removing or inserting, for example, a duvet and / or mattress core can be facilitated.
[0051] For example, the spacer fabric can be at least two-layered with an upper layer forming an outer layer and a woven layer forming an inner or lower layer, preferably made of polyester fiber.
[0052] The inner or lower layer can, for example, be a smooth woven layer, which may also be jacquard and / or patterned, upon which the upper layer of the spacer fabric, made of textured, twisted yarn, in particular multifilament yarn and / or a multifilament yarn with bioceramic particles, can be built. Simultaneously, a fine-knit structure, in particular made of regenerated fibers and / or viscose and / or lyocell and / or fibers with bioceramic particles, can be formed on the outer surface of the lower layer facing away from the upper layer.
[0053] According to one embodiment, the fabric further comprises a middle layer which is interwoven at least at certain points and / or at least partially with the upper and / or lower layers. The middle layer can serve to increase the fabric's volume. This can also enhance user comfort.
[0054] According to one embodiment, the middle layer is at least partially formed from a monofilament yarn, in particular polyester yarn, smooth polyester yarn, polyethylene yarn, smooth polyethylene yarn, polyamide yarn, smooth polyamide yarn, and / or one of the aforementioned yarns with bioceramic particles.
[0055] According to one embodiment, the middle layer is at least partially made of a multifilament yarn, for example a textured, twisted multifilament yarn, in particular a multifilament yarn with bioceramic particles.
[0056] According to one embodiment, the middle layer is at least partially made of a natural fiber. This offers the advantages previously explained regarding natural fibers.
[0057] According to one embodiment, the recesses extend at least substantially over the thickness of the top layer and, optionally, the middle layer. In particular, the recesses can extend completely through the top layer, so that the recesses can form and / or represent openings in the top layer.
[0058] The cutouts can, for example, extend at least substantially across the entire thickness of the top layer, that is, from the outside to the inner or bottom layer, or very close to it, to allow for optimal climate control with regard to air and moisture exchange between the two sides of the fabric. Furthermore, the depth of the cutout can increase the softness of the spacer fabric top layer, thus improving its feel.
[0059] According to one embodiment, the recesses extend at least substantially over one thickness of the lower layer and, optionally, the middle layer. In particular, the recesses can extend completely through the lower layer, so that the recesses can form and / or represent openings in the lower layer.
[0060] The cutouts can, for example, extend at least substantially across the entire thickness of the lower layer, that is, from the outer surface to the inner or upper layer, or very close to it, to allow for optimal climate control with regard to air and moisture exchange between the two sides of the fabric. Furthermore, the depth of the cutout can increase the softness of the lower spacer fabric layer, thus improving the feel.
[0061] The fabric can also be three-layered with a middle layer, such as one knitted with the top layer, containing a monofilament yarn as filler. This allows for stabilization and the desired volumization of the spacer fabric while maintaining high air and moisture permeability. The monofilament yarn can be made at least partially of polyester, but other synthetic fibers such as polyamide, polyethylene, or fibers made from the aforementioned materials with bioceramic particles can also be used.
[0062] To give an outward-facing surface or the outer side of the spacer fabric a particularly smooth and pleasant feel, the surface or outer side surrounding the cutouts can be made of finer knit stitches compared to other areas of the outer side. This can apply to the outer side of the upper and / or lower layer.
[0063] According to one embodiment, the upper layer comprises 50% to 70%, and in particular 55% to 60%, of the fabric by weight. Studies have shown that this weight percentage is particularly advantageous with regard to comfort and microclimate control.
[0064] According to one embodiment, the lower layer has a weight fraction of 20% to 30%, in particular 25% to 30%, of the material.
[0065] According to one embodiment, a middle layer has a weight fraction of 10% to 20%, in particular 15% to 20%, of the fabric. When using a filler, optimal results with regard to air permeability, stabilization and volumization were found with a weight fraction of 10% to 20%, in particular 15% to 20%, of the middle layer of the fabric.
[0066] According to one embodiment, the material has a weight of 250 g / m². 2 - 300 g / m 2 or from 100 g / m² 2 - 250 g / m 2 This allows the fabric to have the necessary durability while remaining easy to handle in terms of its weight during both production and use.
[0067] According to one embodiment, the fabric or covering material from the textile is identical on all sides. In other words, the fabric or covering can be identical on all sides, i.e., on the top, the bottom, and any longitudinal and transverse sides, although it is also conceivable to design different sides of the covering differently.
[0068] The identical construction of all sides allows for particularly simple manufacturing, and due to the high breathability of the fabric, a ventilation strip found on the transverse and longitudinal sides, as is common in known covers, especially blanket covers, can be dispensed with.
[0069] According to one embodiment, the textile for a cover has at least a partially circumferential closure, in particular a zipper, which can be opened or closed to insert or remove, for example, a duvet. To facilitate the insertion and removal of a duvet in particular, it can be advantageous if the cover has at least a partially circumferential closure, in particular a zipper.
[0070] Furthermore, to make handling easier, a mattress covered with the textile or cover may have at least one handle sewn onto the textile.
[0071] The textile for a cover may also be washable, for example at a temperature of at least 30°C, at least 40°C, at least 50°C, at least 60°C, at least 70°C, at least 80°C, or at least 90°C. Another aspect of the present disclosure relates to the use of a fabric or textile for a cover for a duvet or blanket, for example, a duvet or comforter cover, for a mattress, for example, a mattress cover, and / or for a cover for a seat, a cushion, a sofa, a couch, upholstered furniture, a chair, seating furniture, or the like. Alternatively or additionally, the present disclosure may relate to the use of a cover for a duvet, a blanket cover, a comforter cover, a mattress topper, a mattress cover, a seat cover, and / or a cover for a seat, a cushion, a sofa, a couch, upholstered furniture, a chair, seating furniture, or the like.
[0072] The fabric comprises at least one upper layer and one lower layer, wherein the upper and lower layers are at least partially arranged one above the other, and wherein at least the upper layer of the fabric, or the fabric as a whole, is formed entirely or at least partially from a spacer fabric, for example, a 3D spacer fabric, the spacer fabric comprising fibers with bioceramic particles. At least one outer surface of the upper layer facing away from the lower layer has several cutouts. Alternatively or additionally, at least one outer surface of the lower layer facing away from the upper layer may have several cutouts.
[0073] Optionally, at least the outer surface of the upper layer and / or the outer surface of the lower layer may comprise a fine-knit structure, in particular made of viscose and / or lyocell and / or a regenerated fiber and / or fibers with bioceramic particles.
[0074] Optionally, the top and / or bottom layer of the cover fabric can be at least partially made of a natural fiber. In addition to fibers with bioceramic particles and / or viscose and / or lyocell, for example, regenerated fibers or other cellulose-based fibers, such as modal and / or cupro fibers, can also be used in the fine-knit structure, forming at least part or even the entire fabric.

[0084] Brief description of the characters
[0085] It shows:
[0086] Fig. 1 shows a perspective view of a textile designed according to the invention and mounted on a mattress core.
[0087] Fig. 2 is a highly simplified partial top view of an outer surface of the textile, and
[0088] Fig. 3 shows a partial schematic cross-sectional view through a section of the textile.
[0089] The figures are schematic only and not to scale. Similar or identical elements in the figures are marked with similar or identical reference symbols.
[0090] Detailed description of implementation examples
[0091] Referring to Fig. 1, an exemplary textile 1, or mattress cover, is shown stretched over a mattress core 2, wherein the textile 1 forms a first lying surface on its upper side 3 and a second lying surface for a user on its opposite lower side 4. The textile 1 in Fig. 1 is shown only as an example of a mattress cover. Alternatively, the textile 1 can be designed as a seat cover to accommodate a seat cushion core, as a duvet cover to accommodate a duvet, or as a pillowcase to accommodate a cushion.
[0092] The textile 1 is made entirely of the same fabric 5, with the lateral transverse surfaces 6 and longitudinal surfaces 7 optionally transitioning seamlessly into the top 6 and bottom 7. However, in other versions, the fabric 5 surfaces may be separated by seams and, if necessary, a piping strip.
[0093] In particular, when the textile 1 is designed as a duvet cover or pillowcase, the transverse surfaces 6 and longitudinal surfaces 7 can be omitted.
[0094] A circumferential closure 8 in the form of a zipper is sewn into the mattress cover on the transverse surfaces 6 and longitudinal sides 7 for inserting and removing the mattress core 2. In addition, several handles 9 are provided on the side longitudinal surfaces 7 for lifting the mattress core 2 enclosed by the mattress cover 1; only one handle 9 is shown as an example.
[0095] As can be seen in section X in Fig. 1, which represents the entire surface of the textile 1, and in Fig. 2 and Fig. 3, the fabric 5 is formed with a spacer fabric 10, such as a 3D spacer fabric, up to its outer surface 11.
[0096] The material ö has a honeycomb-like mesh structure with outwardly open recesses 12 in a regular, finely structured arrangement. The recesses 12 preferably have a round, rounded, elliptical and / or oval cross-section facing outwards, which in the unstretched state can be, for example, 2 mm to 4 mm in width and about 3 mm to 5 mm in length.
[0097] The material webs 13 made of spacer fabric 10 located between the offset and regularly arranged recesses 12 can be at least approximately the same width.
[0098] The fabric 5 of textile 1 is designed as a three-layer spacer fabric with an upper layer 14 forming an outer surface 11, a middle layer 15 forming part of the spacer fabric 10 and knitted with the upper layer 14, and an inner or lower layer 16 that is knitted with the upper layer 14 and / or the middle layer 15. The lower layer 16 also forms an outer surface 18.
[0099] The upper layer 14 can consist of a monofilament yarn, such as smooth monofilament yarn, or a multifilament yarn, such as textured, twisted multifilament yarn. Similarly, the lower layer 16 can also consist of a monofilament yarn, such as smooth monofilament yarn, or a multifilament yarn, such as textured, twisted multifilament yarn. Likewise, the middle layer 15 can be at least partially composed of monofilament or multifilament yarns. Furthermore, all of the aforementioned yarns can also contain bioceramic particles.
[0100] One or more of the upper layer 14, the middle layer 15, and the lower layer 16 may contain natural fibers and / or be at least partially composed of natural fibers. These natural fibers may include, for example, animal hair fibers, wool fibers, cotton fibers, eucalyptus fibers, bamboo fibers, linen fibers, wood fibers, flax fibers, hemp fibers, silk fibers, plant fibers, and / or a combination thereof. Furthermore, all of the aforementioned fibers may also contain bioceramic particles. Such natural fibers may, compared to synthetic fibers, be characterized by increased sustainability, odor neutrality, skin compatibility, durability, and / or robustness.
[0101] The upper layer 14 also features a fine-knit structure 17 on its outer surface 11, which gives the surface a soft feel. Similarly, the lower layer 16 features the fine-knit structure 17 on its outer surface 18. To enable a soft or cuddly surface feel on the respective outer surface 11 and / or 18 of the textile 1, the fine-knit structure 17 can be made at least partially, but in particular entirely, of viscose and / or lyocell and / or fibers with bioceramic particles, but also of regenerated fibers or other cellulose-based fibers, such as modal and cupro fibers.
[0102] With regard to thickness, the middle layer 15 in the advantageous embodiment shown is dimensioned such that it occupies at least 70% to 80% of the total thickness of the fabric 5 in order to make the most of the microclimatic advantages of the spacer fabric 10.
[0103] To allow for maximum air circulation and optimal moisture transport to the outer surface 11, the honeycomb-like openings 12 extend essentially across the thickness of the upper layer 14 and the middle layer 15 to the adjacent lower layer 16, so that the fabric 5 exhibits high flexibility and lateral stretchability due to the openings 12. The vertical elasticity results in a softness that can be defined by the filler material of the middle layer 14, depending on the desired degree of softness.
[0104] It is understood that, depending on the application, fabric 5 can be produced using all known manufacturing processes for spacer fabrics on circular knitting machines as well as using all known finishing processes, such as a washing, bleaching and shrinking process following the knitting process.
[0105] All features described with reference to one of the above embodiments for a cover for a duvet or mattress also apply to a cover for a seat and / or a cushion. In other words, any cover disclosed in the description and all described embodiments can also be used for seats and / or cushions. The textile according to the invention for a cover can also be used for a seat and / or cushion as a seat cover or cushion cover, respectively.
[0106] It should also be noted that “comprehensive” and “showing” do not exclude other elements and that the indefinite articles “a” or “an” do not exclude a multitude.
[0107] Furthermore, it should be noted that features described with reference to one of the above embodiments can also be used in combination with other features of other embodiments described above. Reference numerals in the claims are not to be considered limitations.
