Definitions

• 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.
• the textile element is according to DE 20 2016 104 745 U1
• the textile element is limited to a textile element that has a net structure.
• the textile element is not made of bamboo viscose, but of natural fibers. According to a preferred embodiment, these natural fibers can be in DE 20 2016 104 745 U1 bamboo fibers and/or coconut fibers.
• 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. Furthermore, prior art textiles made from bamboo materials are limited to single jersey fabrics and textile elements with a mesh structure.
• 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.
• 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.
• the at least one additive is selected from the group consisting of recycled polyester, elastane, cotton, silk
• 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.
• 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.
• 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.
• the term “textile fabric” refers to viscose textiles made from bamboo pulp, such as bamboo viscose.
• 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).
• plant origin such as cotton, linen, coconut, jute

• chemical origin chemical fibers made from natural polymers, such as viscose, cupro, modal, lyocell, acetate, or triacetate
• synthetic polymers such as polyester, polyamide, polyacrylic, elastane, polypropylene, or polyurethan
• 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.
• 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.
• the term "knitted” or “knitted textile fabric” 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 knitted and crocheted yarns, whereby different yarn systems are joined to form loops. Therefore, according to the invention, the term “knitted” is to be understood as textile fabric. The fabric is created by forming loops. Knitting can be done mechanically, for example, using a knitting machine or a overlock machine.
• the term “knitted fabric” refers to knitted fabrics made from a single yarn thread and are circular or flat knitted.
• warp-knitted fabric refers to knitted fabrics in which numerous threads are used, with a separate thread and needle for each loop. 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.
• 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.
• viscose 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., reprocessed, state. This starting material is then dissolved in various chemicals until a viscous mass is formed. This viscous mass is then extruded through nozzles into a dilute sulfuric acid solution using a dry or wet spinning process.
• the viscose is pressed, resulting in the formation of long, thin, continuous threads.
• Production methods 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 method familiar to those skilled in the art. Depending on the production method, different matte or glossy viscose qualities are obtained, with visual similarities to cotton, wool, silk, or similar materials.
• 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.
• 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.
