Description

[0001] The present invention relates to a textile fabric made of a bamboo viscose material and at least one additive, and to the use of the textile fabric for the manufacture of a garment and / or a mask.

[0002] Prior art discloses, on the one hand, single jersey textiles made from a bamboo material for use in socks and underwear. On the other hand, DE 20 2016 104 745 U1 discloses a textile element for use as a baby carrier, which consists of at least 90% natural fibers and / or fibers made from natural fibers.

[0003] Firstly, the textile element according to DE 20 2016 104 745 U1 is limited to a textile element that has a net structure. Secondly, the textile element does not consist of bamboo viscose, but of natural fibers. According to a preferred embodiment in DE 20 2016 104 745 U1, these natural fibers can be bamboo fibers and / or coconut fibers.

[0004] However, the prior art textiles made from bamboo materials have the disadvantage that they cannot be washed at elevated temperatures (e.g., at least 60°C) and / or are not suitable for tumble drying. Therefore, the potential uses of prior art textiles made from bamboo materials are severely limited, as they lose their shape and shrink when washed at elevated temperatures (e.g., at least 60°C) or tumble dried, rendering them unusable after a single wash cycle (e.g., at least 60°C) or a tumble dry cycle. Furthermore, prior art textiles made from bamboo materials are limited to single jersey fabrics and textile elements with a mesh structure.

[0005] The object of the present invention is to overcome the disadvantages of the known prior art, in particular to provide a textile fabric with improved properties that is antibacterial, odor-binding, breathable, skin-friendly, heat- and cold-regulating, has a high moisture absorption capacity and is both washable and suitable for tumble drying.

[0006] This task is solved by the subject matter of the independent claims.

[0007] The foregoing problem is solved in a first aspect by providing a textile fabric, wherein the textile fabric comprises at least bamboo viscose or a bamboo viscose derivative and at least one additive, characterized in that the at least one additive is selected from the group consisting of recycled polyester, elastane, cotton, silk, nonwoven fabric, wool, polyester, recycled cotton, recycled polyamide, polyamide, recycled polypropylene and polypropylene, and that the bamboo viscose or the bamboo viscose derivative has a mass fraction of at least 50 wt.% of the textile fabric, in particular at least 60 wt.% of the textile fabric, and that the at least one additive has a mass fraction between 1 wt.% and 50 wt.% of the textile fabric, in particular between 2 wt.% and 45 wt.% of the textile fabric or between 5 wt.% and 40 wt.% of the textile fabric.

[0008] It has been found that the use of bamboo viscose or a bamboo viscose derivative has beneficial effects on the textile fabric, as bamboo viscose or a bamboo viscose derivative is antibacterial and disinfectant, odor-binding, breathable, and skin-friendly, regulates temperature, and supports moisture absorption and release. Furthermore, the use of bamboo viscose or a bamboo viscose derivative in a textile fabric is ecologically very advantageous, since bamboo cultivation is particularly sustainable and the production of bamboo viscose requires significantly less water than, for example, the production of viscose from other wood-based materials. Bamboo is the fastest-growing plant species in nature, and therefore the bamboo viscose textile raw materials according to the invention can be produced much faster and in a more environmentally friendly way than conventional textile raw materials such as cotton.

[0009] For the purposes of this invention, the term "textile fabric" shall be understood as a planar, usually two-dimensional, flexible material that is versatile and can be used, for example, in the clothing industry. A textile fabric is produced from one or more yarns by a manual or machine textile-forming technique such as knitting, weaving, or crocheting. For the purposes of this invention, the term "textile fabric" refers, figuratively, to a fabric, a textile, a textile element, or similar interchangeable terms familiar to those skilled in the art for a textile fabric. Particularly preferably, for the purposes of this invention, the term "textile fabric" refers to viscose textiles made from bamboo pulp, such as bamboo viscose.

[0010] A "yarn" within the meaning of this invention can consist of fibers of plant origin (so-called natural plant fibers, including cotton, linen, coconut, jute), animal origin (so-called natural animal fibers, including wool, silk, angora, cashmere, horsehair), or chemical origin (chemical fibers made from natural polymers, such as viscose, cupro, modal, lyocell, acetate, or triacetate; or chemical fibers made from synthetic polymers, such as polyester, polyamide, polyacrylic, elastane, polypropylene, or polyurethane). Within the scope of the invention, "fibers" are understood to mean yarns, continuous filaments, cords, fiber cables (for example, for rippling spinning processes), unstrapped or crimped staple fibers, and industrially woven, knitted, braided, or twisted material.

[0011] Yarns or threads can be produced through the spinning process, in which fibers are first opened, cleaned, aligned, drawn, and partially combed. The fibers are then fed into a spinning machine as a drafting sliver, which twists, elongates, and twists the fibers together to create a long thread of the desired fineness. The production of synthetic or near-natural fibers by extruding liquid plastic through nozzles is also called spinning, although the latter can be done using melt spinning, wet spinning, or dry spinning.

[0012] For the purposes of this invention, the term "knitted" or "knitted textile" refers to a textile or textile fabric that is or has been produced using the knitting technique. Knitting is a joining process and refers to the use of combinations of knitting and stitching, whereby different yarn systems are joined to form stitches. Therefore, according to the invention, the term "knitted" is to be understood as a textile fabric that has been produced by stitch formation. Knitting can be done by machine, for example, using a heaving machine or a looper. The term heaving knitwear refers to knitwear that is made from a single yarn thread and is either circular or flat knitted. The term warp-knitted knitwear refers to knitwear in which numerous threads are used, with a separate thread and needle being used for each stitch.Knitted textiles have the particular advantage of being virtually wrinkle-free, lightweight, and highly breathable, making them especially suitable for the production of jersey shirts, jerseys, and nylon tights. Knitted textiles also include lace, curtain fabrics, plush, and velvet. The knitting of a textile fabric according to the invention can be carried out using any knitting process known to those skilled in the art.

[0013] For the purposes of this invention, the term "woven" or "woven fabric" refers to a textile or fabric made from at least two threads or thread systems. These thread systems are called the warp (warp thread, lengthwise) and the weft (weft thread, crosswise), which are crossed during the weaving process. The pre-tensioned warp threads form the base into which the weft threads are successively inserted from one selvedge to the other across the entire width of the woven fabric. The weft thread always moves laterally at a 90° angle through the warp thread, creating the basic textile fabric structure, which is referred to in technical terms as a "fabric". Weaving a textile fabric according to the invention can be carried out using any weaving method known to those skilled in the art.

[0014] The term "viscose" as used in this invention refers to synthetic fibers derived from the sustainable raw material cellulose. Viscose is classified as a near-natural synthetic fiber and, according to the invention, can also be referred to as "rayon" or "regenerated cellulose fiber." Cellulose can be obtained from wood, cotton waste, or bamboo. According to the invention, viscose derived from bamboo is used. The starting material for the bamboo viscose is bamboo cellulose in a regenerated, i.e., recycled, state. This starting material is then dissolved in various chemicals until a viscous mass is formed. This viscous mass is then forced through nozzles into a dilute sulfuric acid solution using a dry or wet spinning process, resulting in the formation of long, thin, continuous filaments.Production processes for manufacturing viscose are known to those skilled in the art, and the production of viscose as a starting material for the manufacture of a textile fabric according to the invention can be carried out by any production process known to those skilled in the art. Depending on the production process, different matte or glossy viscose qualities are obtained, with an optical similarity to cotton, wool, silk, or similar materials.

[0015] Viscose fibers can be considered synthetic cotton, wool, or silk fibers and share similar material properties. Viscose textiles, for example, are soft and comfortable against the skin. Another characteristic of viscose is its exceptional absorbency. Viscose is used in a wide variety of products, such as cleaning cloths, cotton swabs, tampons, packaging films, artificial casings, and banknote paper. Because viscose is highly versatile, comfortable to wear, and easy to care for, it is also used in the production of everyday textiles, especially outerwear, such as sweaters, dresses, accessories, and sportswear.

[0016] For the purposes of this invention, the term "bamboo viscose" refers to viscose obtained from bamboo. The term "bamboo viscose derivative" refers to any derivatized bamboo viscose obtained by modifying "bamboo viscose," for example, by conjugating additional components. Bamboo viscose derivatives can also be obtained by using additional or different detergents, by additional or different solubilization steps, or by additional or different separation process steps. Bamboo viscose derivatives also include chemically modified bamboo viscose substances. Such modifications include, but are not limited to, glycosylation, ubiquitination, lipid conjugation, sumoylation, methylation, and other post-translational modifications of bamboo viscose known to those skilled in the art.

[0017] Within the scope of this invention, the terms "yarn fineness," "yarn thickness," or "titer" of a yarn, fiber, or filament refer to its mass per unit length. High yarn fineness means a lower mass-to-length ratio. According to the invention, yarn fineness can be measured in tex (tex), where one tex corresponds to one gram per 1000 meters. Furthermore, one unit "dtex" or "decitex" denotes one gram per 10,000 meters. One unit "ktex" or "kilotex" denotes one kilogram per 1000 meters. The fineness of a yarn can influence the appearance of a textile surface, such that a fine yarn can produce a very uniform surface appearance, while a coarse yarn can create a more rustic character. It is known to those skilled in the art that older units for yarn fineness are still widely used in the textile industry, such as denier (den), metric number (Nm), and imperial number (Ne).Experts are also aware that the unit "den" corresponds to one gram per 9000 meters. The unit "Nm" corresponds to one meter per gram of yarn. In contrast, the unit "Ne" corresponds to 840 yards per pound.

[0018] According to the invention, the textile fabric comprises at least one additive in addition to bamboo viscose or a bamboo viscose derivative.

[0019] The term "at least one" in the context of this invention shall be understood to mean at least one substance, or 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, or any number of substances. For example, the term "at least one" additive in the context of this invention shall be understood to mean at least one additive, or 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, or any number of additives. Furthermore, the term "at least one" in the context of this invention includes any number of substances or additives, which are preferably uniformly distributed. For the purposes of this invention, the term "at least one" shall also include any number of substances or additives that are unevenly distributed.

[0020] Non-restrictive examples of at least one additive include (i) cellulose fibers such as cotton, rayon or linen; (ii) protein fibers such as silk or wool; (iii) synthetic fibers such as polyester, recycled polyester, elastane, recycled cotton, polyamide, polypropylene, acrylic or nylon; (iv) plant fibers such as jute, flax, ramie, coconut, kapok, sisal, henequen, abaca or hemp.

[0021] Preferably, at least one additive is selected from the group consisting of recycled polyester, elastane, cotton, silk, non-woven fabric, wool, polyester, recycled cotton, recycled polyamide, polyamide, recycled polypropylene and polypropylene.

[0022] In a preferred embodiment, the yarn fineness of the yarn of at least one additive corresponds to more than 0.8 dtex, preferably 0.9 dtex to 300 dtex, particularly preferably 1.5 dtex to 250 dtex, most preferably 2 dtex to 200 dtex.

[0023] Recycled polyester, as used in this invention, refers to any polyester obtained from post-consumer polyester and / or PET material. The use of recycled polyester material offers the particular advantage of being especially environmentally friendly and CO2-neutral, as recycled polyester is primarily obtained from old, used PET bottles. The use of recycled polyester is particularly advantageous because, firstly, it significantly reduces waste. Secondly, recycled polyester offers immense potential for energy savings: it has been shown that, compared to the production of conventional cotton or the production of new polyester, energy savings of 40% to 85% are possible.Furthermore, there is a potential saving of up to 90% of the water required for the production of recycled polyester compared to the water required for the primary production of polyester.

[0024] In a further preferred embodiment, the recycled polyester is produced by a process comprising the following steps: i) Providing PET bottles, wherein the PET bottles are preferably old, used PET bottles; ii) Sorting the provided PET bottles, for example into different shades; iii) Shredding the sorted provided PET bottles; iv) Granulating the shredded, sorted PET bottle material into flakes and / or granules; and v) Cleaning the granulated, shredded, sorted PET bottle material, wherein the cleaning is carried out, for example, by melt filtration.

[0025] According to the invention, the recycled polyester can then be further processed into a textile.

[0026] A further development of the invention relates to a recycled polyester, which is produced by a process comprising the following steps: i) Providing PET bottles, wherein the PET bottles are preferably old, used PET bottles; ii) Sorting the provided PET bottles, for example into different shades; iii) Crushing the sorted provided PET bottles; iv) Splitting the individual molecules of the crushed, sorted PET bottle material by a solvent, wherein the solvent is preferably selected from the group consisting of water, methanol and glycol; and v) Purifying the split, crushed, sorted PET bottle material, wherein the purification is carried out, for example, by melt filtration.

[0027] The individual molecules of polyester that have been split in this way can be used as building blocks for the production of new products, such as new textiles.

[0028] In a particularly preferred embodiment, the composition comprising bamboo viscose or a bamboo viscose derivative and at least one additive is used as yarn for a textile fabric.

[0029] In a preferred embodiment, the textile fabric according to the invention comprises at least bamboo viscose or a bamboo viscose derivative and a recycled polyester, wherein the recycled polyester has a mass fraction of between 25 wt.% and 45 wt.% of the textile fabric, in particular between 30 wt.% and 40 wt.% of the textile fabric or about 35 wt.% of the textile fabric.

[0030] There is a fundamental conflict of interest between, on the one hand, the desire to provide a textile fabric that is antibacterial, odor-binding, breathable and skin-friendly, regulates heat and cold and supports moisture absorption and release, and, on the other hand, the need to provide a textile fabric that is washable and suitable for tumble drying at an elevated temperature of, for example, at least 60°C.

[0031] A composition comprising bamboo viscose or a bamboo viscose derivative and a recycled polyester for use as yarn for a textile fabric is particularly preferred, as this composition has shown particularly surprising and advantageous effects. It has been found that the use of a recycled polyester in a textile fabric according to the invention in a mass fraction between 25 wt.% and 45 wt.% of the textile fabric, in particular between 30 wt.% and 40 wt.% of the textile fabric or about 35 wt.% of the textile fabric, enables the textile fabrics produced to be washable at an elevated temperature of, for example, at least 60°C and suitable for tumble drying. The addition of such a proportion of recycled polyester in the textile fabric (up to 45 wt.% of the textile fabric, preferably up to 35 wt.%)The fact that bamboo viscose (-% of the textile fabric) contains less than 1% of the fabric does not diminish the beneficial effects that bamboo viscose or a bamboo viscose derivative has on a textile fabric, such as its antibacterial effect, breathability, skin compatibility, heat and cold regulation, and its ability to support moisture absorption and release. However, the addition of a sufficiently high proportion of recycled polyester to the textile fabric (at least 25% by weight, preferably about 35% by weight) surprisingly solves the problem of prior art bamboo textiles, namely that these shrink during a washing cycle at an elevated temperature of, for example, at least 60°C, or during a tumble dryer cycle, and are therefore not reusable.

[0032] The measures according to the invention, namely the addition of a sufficiently high proportion of recycled polyester to the bamboo viscose in the textiles, thus overcome the disadvantages of the prior art, since a textile according to the invention comprising bamboo viscose or a bamboo viscose derivative and a recycled polyester, wherein the recycled polyester has a mass fraction of between 25 wt.% and 45 wt.% of the textile, in particular between 30 wt.% and 40 wt.% of the textile or about 35 wt.% of the textile, is washable at an elevated temperature of, for example, at least 60 C° and suitable for tumble drying and is nevertheless antibacterial, odor-binding, breathable and skin-friendly, has a heat- and cold-regulating effect and supports the absorption and release of moisture by the textile.

[0033] According to the invention, a composition of bamboo viscose and recycled polyester is particularly preferred, wherein the composition comprises approximately 65 wt.% bamboo viscose and approximately 35 wt.% recycled polyester, since it has been surprisingly found that textiles consisting of approximately 65 wt.% bamboo viscose and approximately 35 wt.% recycled polyester do not lose their shape or shrink when washed at an elevated temperature of, for example, at least 60°C or tumble dried, so that they remain unchanged and therefore reusable after a washing cycle at an elevated temperature of, for example, at least 60°C or a tumble dryer cycle. Therefore, a textile fabric consisting of approximately 65 wt.% bamboo viscose and approximately 35 wt.% recycled polyester is particularly preferred. This textile fabric is characterized in that it is washable at a temperature of at least 40°C, and particularly at least 60°C, and suitable for tumble drying.

[0034] The recycled polyester content used in the fabric according to the invention contributes to strength and durability, which is particularly suitable for industrial laundering. Furthermore, recycled polyester is environmentally friendly and differs from polyester used in microfiber fabrics in its yarn fineness.

[0035] In a preferred embodiment, the yarn count of the bamboo viscose yarn is approximately 10 to 300 dtex, preferably 50 to 250 dtex, particularly preferably 100 to 200 dtex, and most preferably 140 to 160 dtex or approximately 150 dtex. In a further preferred embodiment, the yarn count of the yarn of the at least one additive is approximately 0.9 to 300 dtex, preferably 1.5 to 250 dtex, and particularly preferably 2.0 to 200 dtex.

[0036] In another embodiment, the yarn count of the bamboo viscose yarn is approximately 10 to 300 dtex, preferably 50 to 250 dtex, particularly preferably 100 to 200 dtex, most preferably 140 to 160 dtex or approximately 150 dtex, and the yarn count of the recycled polyester yarn is 0.9 dtex to 200 dtex, preferably 1.2 dtex to 150 dtex, more preferably 1.5 dtex to 100 dtex, particularly preferably 1.8 dtex to 85 dtex, or approximately 83 dtex.

[0037] In a further preferred embodiment, the yarn count of the bamboo viscose yarn is approximately 10 to 300 dtex, preferably 50 to 250 dtex, particularly preferably 100 to 200 dtex, most preferably 140 to 160 dtex or approximately 150 dtex, and the yarn count of the recycled polyester yarn is 0.9 dtex to 200 dtex, preferably 1.2 dtex to 150 dtex, more preferably 1.5 dtex to 100 dtex, particularly preferably 1.8 dtex to 85 dtex, or approximately 2.0 to 2.2 dtex.

[0038] In one embodiment, the textile fabric according to the invention has a basis weight of 10 grams / m² to 500 grams / m², preferably 50 grams / m² to 400 grams / m², particularly preferably 100 grams / m² to 300 grams / m², and most preferably 150 grams / m² to 200 grams / m². In a particularly preferred embodiment, the textile fabric according to the invention has a basis weight of 170 grams / m².

[0039] In a further preferred embodiment, the textile fabric according to the invention, comprising bamboo viscose and textured recycled polyester, has a basis weight of 10 grams / m² to 500 grams / m², preferably 50 grams / m² to 400 grams / m², particularly preferably 100 grams / m² to 300 grams / m², and most preferably 150 grams / m² to 200 grams / m². In a particularly preferred embodiment, the textile fabric according to the invention, comprising bamboo viscose and textured recycled polyester, has a basis weight of 170 grams / m².

[0040] For the purposes of this invention, the term "approximately" is used to indicate a certain quantity tolerance. According to the invention, "approximately" means ± 10.0%, or ± 5.0%, or ± 1.0%, or ± 0.5%, or ± 0.1%.

[0041] In a further preferred embodiment, the textile fabric according to the invention comprises at least bamboo viscose or a bamboo viscose derivative and elastane, wherein the elastane has a mass fraction of between 1 wt.% and 10 wt.% of the textile fabric, in particular between 2 wt.% and 8 wt.% of the textile fabric or between 2 wt.% and 4 wt.% of the textile fabric.

[0042] The measures according to the invention, namely the addition of a sufficiently high proportion of elastane to the bamboo viscose in the textiles, overcome the disadvantages of the prior art, since a textile according to the invention comprising bamboo viscose or a bamboo viscose derivative and elastane, wherein the elastane has a mass fraction between 1 wt.% and 10 wt.% of the textile, in particular between 2 wt.% and 8 wt.% of the textile or between 2 wt.% and 4 wt.% of the textile, showed particularly surprising and advantageous effects, since such textiles exhibit special strength and elasticity.

[0043] Furthermore, the addition of a sufficiently high proportion of elastane to the textile fabric does not diminish the beneficial effects that bamboo viscose or a bamboo viscose derivative has on a textile fabric, such as the antibacterial effect, breathability, skin compatibility, heat and cold regulating effect and the support of moisture absorption and release.

[0044] In a further preferred embodiment, the textile fabric according to the invention, comprising bamboo viscose and elastane, has a basis weight of 10 grams / m² to 500 grams / m², preferably 50 grams / m² to 400 grams / m², particularly preferably 100 grams / m² to 300 grams / m², and most preferably 150 grams / m² to 200 grams / m². In a particularly preferred embodiment, the textile fabric according to the invention, comprising bamboo viscose and elastane, has a basis weight of 170 grams / m².

[0045] Furthermore, in one embodiment, the yarn count of the bamboo viscose yarn is approximately 10 to 300 dtex, preferably 50 to 250 dtex, particularly preferably 100 to 200 dtex, most preferably 140 to 160 dtex or approximately 150 dtex, and the yarn count of the elastane yarn is 0.9 to 300 dtex, preferably 1.5 to 250 dtex, particularly preferably 2.0 to 200 dtex, most preferably 4.0 to 6.0 dtex, or approximately 4.3 to 5.4 dtex.

[0046] A particularly preferred embodiment also relates to a textile fabric comprising at least bamboo viscose or a bamboo viscose derivative and cotton, wherein the cotton has a mass fraction of between 30 wt.% and 50 wt.% of the textile fabric, in particular between 35 wt.% and 45 wt.% of the textile fabric or about 40 wt.% of the textile fabric.

[0047] According to the invention, recycled cotton, organic cotton, and / or eco-cotton can be used instead of cotton. A further preferred embodiment therefore relates to a textile fabric comprising at least bamboo viscose or a bamboo viscose derivative and recycled cotton, wherein the recycled cotton has a mass fraction of between 30 wt.% and 50 wt.% of the textile fabric, in particular between 35 wt.% and 45 wt.% of the textile fabric, or approximately 40 wt.% of the textile fabric. A further preferred embodiment therefore relates to a textile fabric comprising at least bamboo viscose or a bamboo viscose derivative and organic cotton, wherein the organic cotton has a mass fraction of between 30 wt.% and 50 wt.% of the textile fabric, in particular between 35 wt.% and 45 wt.% of the textile fabric, or approximately 40 wt.% of the textile fabric.A further preferred embodiment also relates to a textile fabric comprising at least bamboo viscose or a bamboo viscose derivative and organic cotton, wherein the organic cotton has a mass fraction of between 30 wt.% and 50 wt.% of the textile fabric, in particular between 35 wt.% and 45 wt.% of the textile fabric or about 40 wt.% of the textile fabric.

[0048] The measures according to the invention, namely the addition of a sufficiently high proportion of cotton, recycled cotton, organic cotton and / or eco-cotton to the bamboo viscose in the textiles, overcome the disadvantages of the prior art, since a textile according to the invention comprising bamboo viscose or a bamboo viscose derivative and cotton, recycled cotton, organic cotton and / or eco-cotton, wherein the cotton, recycled cotton, organic cotton and / or eco-cotton has a mass fraction of between 30 wt.% and 50 wt.% of the textile, in particular between 35 wt.% and 45 wt.% of the textile or about 40 wt.% of the textile, has shown particularly surprising and advantageous effects, since such textiles can, for example, be washed at an elevated temperature of at least 60°C, are suitable for tumble drying and are reusable.

[0049] The addition of a sufficiently high proportion of cotton, recycled cotton, organic cotton, and / or eco-cotton to the textile fabric does not diminish the beneficial effects that bamboo viscose or a bamboo viscose derivative has on a textile fabric, such as its antibacterial properties, breathability, skin compatibility, temperature regulation, and ability to absorb and release moisture. However, the addition of a sufficiently high proportion of cotton, recycled cotton, organic cotton, and / or eco-cotton to the textile fabric surprisingly solves the problem of prior art bamboo textiles, namely that these can shrink during a washing cycle at an elevated temperature of, for example, at least 60°C, or during a tumble dryer cycle, and are therefore not reusable.A textile fabric according to the invention comprising at least bamboo viscose or a bamboo viscose derivative and cotton, recycled cotton, organic cotton and / or eco-cotton is characterized in that it is washable at a temperature of at least 40°C, in particular at least 60°C, and suitable for tumble drying.

[0050] In a further preferred embodiment, the textile fabric according to the invention, comprising bamboo viscose and cotton, has a basis weight of 10 grams / m² to 500 grams / m², preferably 50 grams / m² to 400 grams / m², particularly preferably 100 grams / m² to 300 grams / m², and most preferably 150 grams / m² to 200 grams / m². In a particularly preferred embodiment, the textile fabric according to the invention, comprising bamboo viscose and cotton, has a basis weight of 170 grams / m².

[0051] Furthermore, in one embodiment, the yarn count of the bamboo viscose yarn is approximately 10 to 300 dtex, preferably 50 to 250 dtex, particularly preferably 100 to 200 dtex, most preferably 140 to 160 dtex or approximately 150 dtex, and the yarn count of the cotton yarn is 0.9 to 300 dtex, preferably 1.5 to 250 dtex, particularly preferably 2 to 200 dtex, or approximately 150 dtex.

[0052] In a further preferred embodiment, the textile fabric according to the invention comprises at least bamboo viscose or a bamboo viscose derivative and silk, wherein the silk has a mass fraction of between 30 wt.% and 50 wt.% of the textile fabric, in particular between 35 wt.% and 45 wt.% of the textile fabric or about 40 wt.% of the textile fabric.

[0053] The measures according to the invention, namely the addition of a sufficiently high proportion of silk to the bamboo viscose in the textile fabric, overcome the disadvantages of the prior art, since a textile fabric according to the invention comprising bamboo viscose or a bamboo viscose derivative and silk, wherein the silk has a mass fraction between 30 wt.% and 50 wt.% of the textile fabric, in particular between 35 wt.% and 45 wt.% of the textile fabric or about 40 wt.% of the textile fabric, has shown particularly surprising and advantageous effects, since such textile fabrics can, for example, be washed at an elevated temperature of at least 60°C, are suitable for tumble drying and are reusable.

[0054] The addition of a sufficiently high proportion of silk to the textile fabric does not diminish the beneficial effects that bamboo viscose or a bamboo viscose derivative has on a textile fabric, such as its antibacterial properties, breathability, skin compatibility, temperature regulation, and ability to absorb and release moisture. However, the addition of a sufficiently high proportion of silk to the textile fabric surprisingly solves the problem of prior art bamboo textiles, namely that these can shrink during a washing cycle at an elevated temperature of, for example, at least 60°C, or during a tumble dryer cycle, and are therefore not reusable.A textile fabric according to the invention comprising at least bamboo viscose or a bamboo viscose derivative and silk is characterized in that it is washable at a temperature of at least 40°C, in particular at least 60°C, and suitable for tumble drying.

[0055] In a further preferred embodiment, the textile fabric according to the invention, comprising bamboo viscose and silk, has a basis weight of 10 grams / m² to 500 grams / m², preferably 50 grams / m² to 400 grams / m², particularly preferably 100 grams / m² to 300 grams / m², and most preferably 150 grams / m² to 200 grams / m². In a particularly preferred embodiment, the textile fabric according to the invention, comprising bamboo viscose and silk, has a basis weight of 170 grams / m².

[0056] In one embodiment, the yarn fineness of the bamboo viscose yarn is approximately 10 to 300 dtex, preferably 50 to 250 dtex, particularly preferably 100 to 200 dtex, most preferably 140 to 160 dtex or approximately 150 dtex, and the yarn fineness of the silk yarn is 0.9 to 300 dtex, preferably 1.5 to 250 dtex, particularly preferably 2.0 to 200 dtex, or approximately 100 dtex.

[0057] The textile fabric according to the invention can be any textile fabric familiar to those skilled in the art. In an exemplary embodiment, the textile fabric according to the invention is selected from the group consisting of brocade, chambray, chenille, chiffon, chintz, corduroy, cretonne, damask, denim, flannel, gingham, jacquard, jersey, crepe, linen, lyocell, matelassé, modal, Oxford, percale, piqué, poplin, pleated, ramie, rayon, velvet, satin, satinette, seersucker, knit, lace, curtains, terry cloth, twill, taffeta, tulle, tweed, voile, and woolsey.

[0127] Preferably, the textile fabrics for the masks according to the invention are uniformly knitted with two fibers, wherein the bamboo-viscose yarn is used for the inside of one layer of the mask and wherein the yarn comprising the at least one additive, for example the recycled polyester yarn, is used for the outside of the layer. In a preferred embodiment, a mask according to the invention consists of two or three identical layers, wherein each of the two or three layers has identical dimensions, and wherein each of the two or three layers is placed on top of the other and sewn together according to its identical dimensions.In this process, the two or three layers are preferably laid on top of each other and sewn together in such a way that the inside of the mask, which faces the nose and mouth of the mask wearer, is woven, knitted and / or crocheted from bamboo viscose or a bamboo viscose derivative, since bamboo viscose is antibacterial, odor-binding, breathable, skin-friendly, regulates heat and cold and has a high moisture absorption and release capacity, and the outside of the mask, which faces away from the nose and mouth of the mask wearer, is woven, knitted and / or crocheted from at least one additive, for example recycled polyester yarn.

[0128] By using a textile fabric according to the invention for the production of a mask, a mask can be provided which is washable and suitable for tumble drying at an elevated temperature of, for example, at least 60°C and is easy to wear, and which can prevent infections caused by bacteria and / or viruses, since the use of bamboo viscose or a bamboo viscose derivative for the production of a mask achieves an antibacterial, odor-binding, breathable, skin-friendly, heat- and cold-regulating effect in the mask, and also supports the moisture absorption and release of the mask. Examples Example 1: Investigation of the properties of a bamboo-viscose-recycled polyester pique textile fabric according to the invention.

[0129] In an exemplary embodiment, the bamboo-viscose-recycled polyester pique fabric according to the invention is a two-layered textile (so-called "double-face" article) consisting of 65% bamboo viscose and 35% recycled polyester. The fabric consists, in particular, of single-knit bamboo viscose on one side and recycled polyester pique on the other. The connections are made by a tack stitch on every other needle.

[0130] The properties of the bamboo viscose recycled polyester piqué fabric are summarized in the following Table 1: material Formation of lint or pilling on textile surface Weight Colorfastness to rubbing Colorfastness to washing Stability against washing pH ISO 12945-2:2013 gr / m²< ISO 105 X12:2003 ISO 105:Co6 ISO 25077 ISO 3071: 2006 + / -5% dry wet New 40 / 1 100% Bamboo Ring Yarn 3-4 170 4 3 4 Lengthwise -4% + 2% 6,5 75D / 36F textured recycled polyester Broadly -4% +2%

[0131] Those skilled in the art are aware that in many parts of the textile industry, alongside the SI units "tex" / "detex" / "ktex" for the fineness of a yarn or filament, older units for yarn fineness are still in use, such as the units denier (den), metric number (Nm), and English number (Ne). It is also known to those skilled in the art that one "den" corresponds to one gram per 9000 meters. One "Nm" corresponds to one meter per gram of yarn. In contrast, one "Ne" corresponds to 840 yards per English pound.

[0132] A person skilled in the art can convert the units Ne to dtex, where, for example, 40 / 1 Ne corresponds to 148 dtex. Therefore, a person skilled in the art can easily see from Table 1 that Ne 40 / 1 corresponds to 100% of a bamboo ring yarn, which is equivalent to a bamboo ring yarn with a yarn count of 148 dtex. A person skilled in the art can also see directly and unambiguously from Table 1 that the textured recycled polyester according to the invention, with the unit "75D / 36F", comprises 75 dtex on 36 yarns / filaments, so that the textured recycled polyester according to the invention has a yarn count of approximately 2.0833 dtex.

[0133] The person skilled in the art can also see from Table 1 that the "weight", which is given in grams / m², corresponds to the basis weight of the textile fabric. The textile fabric according to the invention, comprising bamboo viscose and textured recycled polyester, therefore has a basis weight of 170 grams / m². Example 2: Investigation of the skin compatibility of the textile materials according to the invention

[0134] The skin compatibility of an exemplary textile fabric according to the invention comprising 95% bamboo viscose and 5% elastane (270 g / m²) was tested by means of an effect-related investigation of cell activity to exclude a cell-damaging potential using the standardized method according to AW-QM-11.08.03.059: 2017-08 A against L929 fibroblast cells in DMEM with 10% FCS as culture medium.

[0135] The extraction process was carried out by incubating the test material with acidic sweat solution according to standard DIN EN ISO 105-E04 for at least 4 hours with gentle shaking at 37°C; the original sweat extract was adjusted to pH 7.3 - 7.4 and sterile filtered.

[0136] The cell culture was incubated for 24 hours with original sweat extract in 2 dilution levels (80% and 40%).

[0137] Evaluation: After incubation of the cells, formazan production was measured using the MTT test as a measure of viability and compared with the following controls: Solvent control: sweat solution (pH 7.3-7.4); Positive control: 12% DMSO in sweat solution; Negative control: culture medium.

[0138] The percentage vitality was calculated using the following formula:

[0139] Testing the percentage of vitality allows for an assessment of skin compatibility, with the controls showing the following vitality: Positive control: 2% vitality; Negative control: 100% vitality; Solvent control: 100% vitality

[0140] Evaluation criteria: A determined vitality of over 70% compared to the solvent control indicates that the sample is not toxic to cells. The exemplary textiles according to the invention, comprising 95% bamboo viscose and 5% elastane, showed a vitality of 100% at the 80% dilution level and a vitality of 98% at the 40% dilution level. Since the compatibility of a material is given when the cell vitality is over 70% compared to the solvent control, the compatibility of the exemplary textiles according to the invention is given, so that the exemplary textile according to the invention is considered skin-friendly. Example 3: Investigation of the sensitizing potential of the textiles according to the invention

[0141] The sensitizing potential of the textile fabrics according to the invention, comprising 95% bamboo viscose and 5% elastane (270 g / m²), was tested using the ISO-standardized method according to AW-QM-11.08.03.068: 2017-09 A in conjunction with DIN EN ISO 10993-12: 2012-10 and DIN EN ISO 105-E04: 2013-08 by means of a in vitro Screening tests against U937 histiocytes (immune cells) in RPMO with 25 mM HEPES, 2% L-glutamine and 10% FCS as culture medium.

[0142] The extraction process involved incubating the test material with acidic sweat solution according to DIN EN ISO 105-E04 for 24 hours with gentle shaking at 37°C; the original sweat extract was adjusted to pH 7.3–7.4 and sterile filtered. The cell culture was incubated for 48 hours with the original sweat extract.

[0143] Evaluation: The cells react to sensitizing substances by expressing specific surface markers. Antibodies coupled to a fluorescent dye bind specifically to these surface markers. Flow cytometry is used to determine the percentage of cells thus labeled. From this, the "Relative Fluorescence Intensity" (RFI) is calculated.

[0144] Checks: Solvent control: sweat solution (pH 7.3-7.4); Positive control: 1 µg / ml DNCB in sweat solution; Negative control: 0.2% DMSO in sweat solution.

[0145] The relative fluorescence intensity is calculated using the following formula:

[0146] For the purposes of this invention, the abbreviations RFI = Relative Fluorescence Intensity and MFI = Mean Fluorescence Intensity.

[0147] Sensitization testing allows for the assessment of the potential risk of the tested substances triggering allergies.

[0148] Assessment criteria: Sensitizing substances stimulate U937 cells to produce surface markers to which specific fluorescently labeled antibodies can bind. The percentage of positive cells is determined via fluorescence intensity in a flow cytometer. These values ​​form the basis for calculating the RFI according to the equation above. Samples with an RFI of 120% and higher are considered potentially sensitizing.

[0149] Under the specified conditions, the sweat extract from the textiles according to the invention shows biological activity in this test. No sensitization potential of the exemplary textiles according to the invention was detected (RFI < 120). Example 4: Investigation of the antibacterial effect of the textiles according to the invention

Standard PES was used as a control material.

[0151] For this purpose, the textile fabrics according to the invention were inoculated with a defined quantity (3.01 x 10⁵ CFU / ml) of a microbial suspension (inoculum). The microbial growth value over 18 hours on the sample material was then calculated compared to the control material using the following formula: A = log 10 C 18 h − log 10 C oh − log 10 T 18 h − log 10 T oh and determined by the equation log 10 C 0 = log 10 T 0. For the purposes of this invention, the abbreviations C = control material and T = sample material.

[0152] Assessment criteria according to DIN EN ISO 20743 A< :2013-12 are summarized in the following Table 2: Effectiveness of the antibacterial property Antibacterial efficacy value A [log 10 CFU] no A < 2 significant 2 ≤ A < 3 strong A ≥ 3
