Description

The present invention relates to a textile fabric made from a bamboo viscose material and at least one additive, and to the use of the textile fabric to produce a garment and/or a mask.

On the one hand, single jersey textiles made from a bamboo material for use in socks and underwear are known from the prior art. On the other hand goes out DE 20 2016 104 745 U1 a textile element for use as a baby sling, which consists of at least 90% natural fibers and/or fibers made from natural fibers.

On the one hand, the textile element according to DE 20 2016 104 745 U1 limited to a textile element which has a network structure. On the other hand, the textile element is not made of bamboo viscose, but of natural fibers. According to a preferred embodiment, these natural fibers can DE 20 2016 104 745 U1 Be bamboo fibers and / or coconut fibers.

However, the textile fabrics made from bamboo materials known in the prior art have the disadvantage that they cannot be washed at an elevated temperature of, for example, at least 60° C. and/or are not suitable for tumble drying. Therefore, the possible uses of the textile fabrics made from bamboo materials known in the prior art are severely restricted, since they lose their shape and shrink when washed at an elevated temperature of, for example, at least 60 C° or in the dryer, so that they shrink after a washing step at an elevated temperature of at least 60 C° or a dryer cycle cannot be reused. In addition, the textile fabrics made from bamboo materials known in the prior art are limited to single jersey textiles and textile elements with a network structure.

It is an object of the present invention to overcome the disadvantages of the known prior art, in particular to provide a fabric with improved properties, which is antibacterial, odor-binding, breathable, skin-friendly, heat and cold-regulating, has high moisture absorption and is both washable and washable is also suitable for tumble drying.

This object is solved by the subject matter of the independent claims.

The above object is achieved in a first aspect by providing a textile material, the textile material comprising 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, fleece, wool, polyester, recycled cotton, recycled polyamide, polyamide, recycled polypropylene and polypropylene, and that the bamboo viscose or bamboo viscose derivative has a weight fraction of at least 50% by weight of the textile material, in particular at least 60% by weight of the textile material, and that the at least one additive has a mass fraction of between 1% by weight and 50% by weight of the textile material, in particular between 2% by weight and 45% by weight of the fabric, or between 5% and 40% by weight of the fabric.

It was found that the use of bamboo viscose or a bamboo viscose derivative has beneficial effects on the textile material, since bamboo viscose or a bamboo viscose derivative has an antibacterial and disinfecting effect, is odour-binding, breathable and kind to the skin, heat- and regulates the cold and supports the absorption and release of moisture. In addition, the use of bamboo viscose or a bamboo viscose derivative in a textile is ecologically very advantageous, since the cultivation of bamboo is particularly sustainable and the production of bamboo viscose uses significantly less water than, for example, the production of viscose from other wood materials. Bamboo is the fastest growing plant species in nature and thus the bamboo-viscose textile raw materials according to the invention can be produced significantly faster and in a more environmentally friendly manner than conventional textile raw materials such as cotton.

For the purposes of this invention, the term “textile” is to be understood as a flat, mostly two-dimensional, flexible material which can be used in many different ways, for example in the clothing industry. A fabric is made from one or more yarns by a hand or machine textile forming technique such as knitting, weaving or knitting. For the purposes of this invention, the term "fabric" refers to a fabric, a textile, a textile element or similar, interchangeable terms for a fabric that are familiar to the person skilled in the art. The term textile material particularly preferably designates viscose textiles made of bamboo pulp such as bamboo viscose for the purposes of this invention.

A "yarn" within the meaning of this invention can be made from 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. In the context of the invention, “fibers” are understood to mean yarns, continuous filaments, cords, fiber tows (e.g. for tear-jerking processes), uncrimped or crimped staple fibers, industrial woven, knitted, braided or twisted material.

Yarns or threads can be obtained by the "spinning" process technology, in which fibers are first opened, cleaned, parallelized, stretched and partially combed. The fibers are then presented to a spinning machine as a sliver, which then twists, stretches and twists the fibers together, resulting in a long thread of the desired fineness. The production of synthetic or near-natural fibers by forcing liquid plastic out of nozzles is also called "spinning", whereby the latter can be done in the form of melt, wet or dry spinning.

For the purposes of this invention, the term "knitted" or "knitted fabric" means a textile or fabric which is or has been made by the technique of knitting. Knitting is a joining process and refers to the use of knitting and stitch combinations, whereby different thread systems are connected to stitches. Therefore, according to the invention, the term "knitted fabric" should be understood as a textile fabric be created by stitch formation. Knitting can be done by machine, for example by means of a weaving machine or a linking machine. The term weft knitted goods refers to knitted goods that are made from a single yarn thread and are circular or flat knitted products. The term warp knit fabrics refers to knit fabrics that use multiple threads, with a separate thread and needle used for each stitch. Knitted textile goods have the particular advantage that they hardly wrinkle, are light and particularly breathable, so they are used in particular for the production of jersey shirts, tricots and nylon tights. Knitted fabrics also include lace, curtain fabrics, plush and velvet. A textile fabric according to the invention can be knitted by any knitting method which is familiar to the person skilled in the art.

For purposes of this invention, the term "woven" or "woven fabric" means a fabric or fabric made from at least two threads or thread systems. These thread systems are called warp (longitudinal warp) and weft (transverse weft), which are crossed over during the weaving process. The pre-tensioned warp threads form the carrier, into which the weft threads are successively drawn from one selvedge to the other through the entire weaving width. The weft thread always moves laterally through the warp thread at a 90° angle, which creates the basic textile fabric structure, which is referred to as "fabric" in technical jargon. A fabric of the invention can be woven by any weaving process known to those skilled in the art.

The term "viscose" in the context of this invention refers to synthetic fibers that are obtained from the sustainable raw material cellulose. Viscose is assigned to the near-natural synthetic fibers and according to the invention can also be referred to as "rayon staple" or as "regenerated cellulose fiber". Cellulose can be obtained from wood, cotton waste or bamboo. According to the invention, viscose is used which was obtained from bamboo. The starting material for bamboo viscose is bamboo cellulose in a regenerated, i.e. reprocessed, state. This starting material is then dissolved in various chemicals until a viscous, viscous mass is formed. This thick, viscous mass is then injected into a dilute sulfuric acid solution through nozzles in a dry or wet spinning process pressed, resulting in the formation of long, thin filaments. Production processes for the production of viscose are known to the person skilled in the art, it being possible for the production of viscose as the starting material for the production of a textile fabric according to the invention to be carried out by any production process familiar to the person skilled in the art. Depending on the production process, there are different matt or shiny viscose qualities with a visual similarity to cotton, wool, silk or the like.

Viscose fibers can be understood as synthetic cotton fibers, wool fibers or silk fibers and also have comparable material properties. Viscose textiles, for example, have skin-friendly soft and comfortable wearing properties. Viscose is also characterized by its extremely strong absorbency. Viscose is used in a variety of areas of life, for example in the form of cleaning cloths, cotton swabs, tampons, packaging films, artificial casings and paper for banknotes. Since viscose can be shaped extremely variably, is very comfortable to wear and easy to care for, viscose is also used for the production of functional textiles, especially in the field of outerwear, for example for the production of sweaters, dresses, accessories and sportswear.

For the purposes of this invention, the term "bamboo viscose" denotes viscose obtained from bamboo. The term "bamboo viscose derivative" denotes any derivatized bamboo viscose obtained by modification of a "bamboo viscose", for example by conjugation of additional components. Bamboo viscose derivatives can also result from the use of additional or different detergents, additional or different solubilization steps, or additional or different separation process steps. Bamboo viscose derivatives also include chemically modified bamboo viscose fabrics. 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.

In the context of this invention, the term “yarn fineness”, “yarn count” or “titer” of a yarn, a fiber or a filament designates its length-related mass. A high yarn count means a smaller mass to length ratio. According to the invention, the yarn count in Tex (tex) measured, with a "tex" a Equivalent to grams per 1000 meters. In addition, a unit "dtex" or "dezitex" denotes 1 gram per 10,000 meters. A unit "ktex" or "kilotex" means 1 kilogram per 1000 meters. The fineness of a yarn can influence the appearance of a textile surface in such a way that a very uniform surface appearance can be achieved with a fine yarn and a more rustic character can be achieved with a coarse yarn. Those skilled in the art are aware that much of the textile industry still uses old units of yarn count, such as denier (den), metric number (Nm), and English number (Ne). Here, the person skilled in the art is also familiar with the fact that the unit "den" corresponds to one gram per 9000 meters. The unit "Nm" corresponds to one meter per gram of yarn. On the other hand, the unit "Ne" corresponds to 840 yards per engl. Pound.

According to the invention, the textile material comprises at least one additive in addition to bamboo viscose or a bamboo viscose derivative.

For the purposes of this invention, the term "at least one" should be understood as at least one single 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 can be understood. For example, the term "at least one" additive in the context of this invention should be understood as 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. In addition, the term "at least one" in the context of this invention includes any number of substances or additives, which are preferably evenly distributed. For the purposes of this invention, however, the term “at least one” should also include any number of substances or additives that are unevenly distributed.

Non-limiting examples of the at least one additive include (i) cellulosic fibers such as cotton, rayon, or linen; (ii) proteinaceous fibers such as silk, or wool; (iii) synthetic fibers such as polyester, recycled polyester, elastane, recycled cotton, polyamide, polypropylene, acrylic or nylon; (iv) Vegetable fibers from jute, flax, ramie, coir, kapok, sisal, henequen, abaca, or hemp.

The at least one additive is preferably selected from the group consisting of recycled polyester, elastane, cotton, silk, fleece, wool, polyester, recycled cotton, recycled polyamide, polyamide, recycled polypropylene and polypropylene. In a preferred embodiment, the yarn fineness of the yarn of the 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.

For the purposes of this invention, recycled polyester refers to any polyester that has been obtained from old polyester and/or PET material. The use of polyester recycling material has the particular advantage of being particularly environmentally friendly and CO2-neutral, because recycled polyester is obtained from old, used PET bottles in particular. The use of recycled polyester is particularly preferred because, on the one hand, the waste problem is significantly reduced. In addition, the recycled polyester holds an immense savings potential in terms of the energy used: It has been shown that compared to the production of conventional cotton or compared to the new production of polyester, a percentage saving potential of the energy used of 40% to 85% is possible. In addition, there is potential for savings of up to 90% of the water required for the production of recycled polyester compared to the water required for the initial production of polyester.

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

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

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, the recycled polyester having a mass fraction of between 25% and 45% by weight of the textile fabric, in particular between 30 and 40% by weight of the fabric, or about 35% by weight of the fabric.

There is a fundamental conflict of interest between, on the one hand, the desire to provide a textile that is antibacterial, odour-binding, breathable and kind to the skin, regulates heat and cold and supports moisture absorption and release, and, on the other hand, the provision of a textile that can be used at an elevated temperature of For example, it is washable at at least 60 °C and suitable for tumble drying.

A composition comprising bamboo viscose or a bamboo viscose derivative and a recycled polyester for use as a yarn for a textile fabric is particularly preferred, since this composition showed particularly surprising and advantageous effects. It has been found that the use of a recycled polyester in a fabric according to the invention in a proportion by weight between 25% and 45% by weight of the fabric, in particular between 30% and 40% by weight of the fabric or about 35% by weight of the fabric allows the fabrics produced to be washable and tumble dryable at an elevated temperature of, for example, at least 60°C. Furthermore, the addition of such a proportion of recycled polyester in the fabric (up to 45% by weight of the fabric, preferably up to 35% by weight of the fabric) does not diminish the beneficial effects that bamboo viscose or a bamboo viscose Derivative on a textile has, for example, the antibacterial effect, the breathability, the skin compatibility, the heat and cold regulating effect and the support of moisture absorption and release. However, the addition of a sufficiently high proportion of recycled polyester in the fabric (at least 25% by weight, preferably about 35% by weight) surprisingly solves the problem of the bamboo fabrics known in the prior art, namely that they at a Wash step at an elevated temperature of, for example, at least 60 C ° or a dryer cycle and are therefore not reusable.

The measures according to the invention, namely the admixture of a sufficiently high proportion of recycled polyester to the bamboo viscose in the textile fabrics, the disadvantages of the prior art are overcome, since a textile fabric according to the invention comprises bamboo viscose or a bamboo viscose derivative and a recycled polyester, the recycled polyester making up a mass fraction of between 25% and 45% by weight of the fabric, more preferably between 30% and 40% by weight of the fabric, or about 35% by weight of the Textile material has, at an elevated temperature of, for example, at least 60 C°, is washable and suitable for tumble drying and yet is antibacterial, odor-binding, breathable and kind to the skin, has a heat- and cold-regulating effect and supports the absorption and release of moisture by the textile material.

According to the invention, a composition of bamboo viscose and recycled polyester is particularly preferred, the composition comprising about 65% by weight bamboo viscose and about 35% by weight recycled polyester, since it was surprisingly found that fabrics consisting of about 65% by weight bamboo viscose and about 35% by weight recycled polyester does not lose its shape or shrink when washed at a higher temperature of, for example, at least 60 C° or in the dryer, so that it does not shrink after a washing step at a higher temperature Temperature of, for example, at least 60 C ° or a dryer run remain unchanged and are therefore reusable. Therefore, a fabric composed of about 65% by weight bamboo viscose and about 35% by weight recycled polyester is particularly preferred. This textile material is characterized in that it can be washed at a temperature of at least 40° C., in particular at least 60° C., and is suitable for tumble drying.

The recycled polyester used according to the invention in the fabric is used for strength and durability, which is particularly useful in industrial laundering. In addition, recycled polyester is environmentally friendly and differs from polyester, which is used for microfibre fabrics, in the fineness of its yarn.

In a preferred embodiment, the fineness of the bamboo viscose yarn corresponds to about 10 to 300 dtex, preferably 50 to 250 dtex, particularly preferably 100 to 200 dtex, very particularly preferably 140 to 160 dtex or about 150 dtex.

In a further preferred embodiment, the textile material according to the invention comprises at least bamboo viscose or a bamboo viscose derivative and elastane, the elastane making up a proportion by mass of between 1% and 10% by weight of the textile material, in particular between 2% by weight. and 8% by weight of the fabric, or between 2% and 4% by weight of the fabric.

The measures according to the invention, namely the admixture of a sufficiently high proportion of elastane to the bamboo viscose in the textile fabrics, overcome the disadvantages of the prior art, since a textile material according to the invention comprises bamboo viscose or a bamboo viscose derivative and elastane, where the elastane makes up between 1% and 10% by weight of the textile fabric, in particular between 2% and 8% by weight of the fabric or between 2% and 4% by weight of the fabric, showed particularly surprising and advantageous effects, since such fabrics have a particular strength and elasticity.

The addition of a sufficiently high proportion of elastane in the textile material also does not reduce the beneficial effects that bamboo viscose or a bamboo viscose derivative has on a textile material, such as the antibacterial effect, breathability, skin compatibility, heat and cold regulation Effect and the support of moisture absorption and release.

In a further preferred embodiment, the textile material according to the invention comprising bamboo viscose and elastane has a basis weight of 10 grams/m ² to 500 grams/m ² , preferably 50 grams/m ² to 400 grams/m ² , particularly preferably 100 grams/m 2 m ² to 300 grams/m ² , most preferably from 150 grams/m ² to 200 grams/m ² . In a particularly preferred embodiment, the textile material according to the invention comprising bamboo viscose and elastane has a basis weight of 170 grams/m ² .

In addition, in one embodiment, the yarn count of the bamboo viscose yarn corresponds to about 10 to 300 dtex, preferably 50 to 250 dtex, particularly preferably 100 to 200 dtex, very particularly preferably 140 to 160 dtex or about 150 dtex, and the yarn count of the elastane yarn 0.9 to 300 dtex, preferably 1.5 to 250 dtex, more preferably 2.0 to 200 dtex, most preferably 4.0 to 6.0 dtex, or about 4.3 to 5.4 dtex.

A particularly preferred embodiment also relates to a textile fabric which comprises at least bamboo viscose or a bamboo viscose derivative and cotton, the cotton making up a mass fraction of between 30% by weight and 50% by weight of the textile fabric, in particular between 35% by weight and -% and 45% by weight of the fabric, or about 40% by weight of the fabric.

According to the invention, recycled cotton, organic cotton and/or ecological cotton can also be used instead of cotton. A further preferred embodiment therefore also relates to a fabric which comprises at least bamboo viscose or a bamboo viscose derivative and recycled cotton, the Recycled cotton has a mass fraction between 30% and 50% by weight of the fabric, in particular between 35% and 45% by weight of the fabric or about 40% by weight of the fabric. An embodiment that is also preferred therefore also relates to a textile material which comprises at least bamboo viscose or a bamboo viscose derivative and organic cotton, the organic cotton making up a proportion by mass of between 30% by weight and 50% by weight of the textile material, especially between 35% and 45% by weight of the fabric, or about 40% by weight of the fabric.

The measures according to the invention, namely the addition of a sufficiently high proportion of cotton, recycled cotton, organic cotton and/or organic cotton to the bamboo viscose in the textile fabrics, overcome the disadvantages of the prior art, since a textile fabric according to the invention comprehensively Bamboo viscose or a bamboo viscose derivative and cotton, recycled cotton, organic cotton and/or organic cotton, the cotton, recycled cotton, organic cotton and/or organic cotton having a mass fraction of between 30 wt. -% and 50% by weight of the fabric, in particular between 35% by weight and 45% by weight of the fabric or about 40% by weight of the fabric, showed particularly surprising and advantageous effects, since such fabrics, for example, can be washed at a higher temperature of at least 60 C°, are suitable for tumble drying and are reusable.

Furthermore, the addition of a sufficiently high proportion of cotton, recycled cotton, organic cotton and/or organic cotton in the fabric does not reduce the beneficial effects that bamboo viscose or a bamboo viscose derivative has on a fabric such as the antibacterial effect, breathability, skin compatibility, heat and cold regulating effect and support for moisture absorption and release. However, the addition of a sufficiently high proportion of cotton, recycled cotton, organic cotton and/or eco-cotton in the fabric surprisingly solves the problem of the prior art known bamboo fabrics, namely that these can shrink during a washing step at an elevated temperature of, for example, at least 60 C° or through a dryer cycle and are therefore not reusable. A fabric according to the invention comprising at least bamboo viscose or a bamboo viscose derivative and cotton, recycled cotton, organic cotton and/or organic cotton is characterized in that it can be washed at a temperature of at least 40 C°, in particular at least 60 C° and suitable for tumble drying.

In a further preferred embodiment, the textile material according to the invention comprises at least bamboo viscose or a bamboo viscose derivative and silk, the silk having a mass fraction of between 30% by weight and 50% by weight of the textile material, in particular between 35% by weight. % and 45% by weight of the fabric, or about 40% by weight of the fabric.

The measures according to the invention, namely the admixture of a sufficiently high proportion of silk to the bamboo viscose in the fabric, overcome the disadvantages of the prior art, since a fabric according to the invention comprising bamboo viscose or a bamboo viscose derivative and silk, wherein the silk accounts for between 30% and 50% by weight of the fabric, in particular between 35% and 45% by weight of the fabric or about 40% by weight of the Textile material, has shown particularly surprising and advantageous effects, since such textile materials can be washed, for example, at an elevated temperature of at least 60° C., are suitable for tumble drying and can be reused.

The addition of a sufficiently high proportion of silk in the textile material also does not reduce the beneficial effects that bamboo viscose or a bamboo viscose derivative has on a textile material, such as the antibacterial effect, breathability, skin compatibility, heat and cold regulation Effect and the support of moisture absorption and release. However, the addition of a sufficiently high proportion of silk in the textile material surprisingly solves the problem of the bamboo textile materials known in the prior art, namely that they can shrink during a washing step at an elevated temperature of, for example, at least 60 C° or a dryer run and as a result are not reusable. A textile material according to the invention comprising at least bamboo viscose or a bamboo viscose derivative and silk is characterized in that it can be washed at a temperature of at least 40° C., in particular at least 60° C., and is suitable for tumble drying.

examples Example 1 Investigation of the properties of a bamboo viscose recycled polyester pique fabric according to the invention

In an exemplary embodiment, the bamboo-viscose recycled polyester pique fabric of the invention is a two-layer fabric (so-called "double-face" article) consisting of 65% bamboo viscose and 35% recycled polyester. Specifically, the textile fabric consists of single-knit bamboo viscose on one side and recycled polyester pique on the other. Connections are made by a tuck pattern on every other needle.

The properties of the bamboo viscose recycled polyester pique fabric are summarized in Table 1 below: material Formation of lint or nodules on the textile surface Weight Color fastness to rubbing Color fastness to washing Stability to washing pH ISO 12945-2:2013 gr/m ² ISO105X12:2003 ISO 105:C06 ISO 25077 ISO 3071:2006 +/-5% dry wet Ne 40/1 100% bamboo ring yarn 3-4 170 4 3 4 Lengthwise -4% + 2% 6.5 75D/36F textured recycled polyester Latitude -4% + 2%

The person skilled in the art is familiar with the fact that in large parts of the textile industry, in addition to the SI units "tex"/"detex"/"ktex" for the fineness of a yarn or filament, old units for yarn fineness are still used, for example the units Denier (den), metric number (Nm) and English number (Ne). Here, the person skilled in the art is also familiar with the fact that the unit "den" corresponds to one gram per 9000 meters. The unit "Nm" corresponds to one meter per gram of yarn. On the other hand, the unit "ne" equals 840 yards per pound.

Thus, a person skilled in the art is able to convert the units Ne into dtex, with 40/1 Ne corresponding to 148 dtex, for example. Therefore, the person skilled in the art can see from Table 1 without any technical difficulties that Ne 40/1 100% of a bamboo ring-spun yarn corresponds to a bamboo ring-spun yarn with a yarn count of 148 dtex. Table 1 also immediately and unambiguously shows the person skilled in the art that the textured recycled polyester according to the invention with the unit "75D/36F" comprises 75 dtex to 36 yarns/filaments, so that the textured recycled polyester according to the invention has a yarn count of about 2.0833 dtex having.

The person skilled in the art will also see from Table 1 that the "weight", which is given in grams/m ² , corresponds to the basis weight of the fabric. The textile fabric according to the invention comprising bamboo viscose and textured recycled polyester therefore has a basis weight of 170 grams/m ² .

Example 2 Investigation of the skin tolerance of the textile fabrics according to the invention

The extraction process was carried out by incubating the test substance with an acidic sweat solution for at least 4 hours in accordance with the DIN EN ISO 105-E04 standard 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 24 hours with original sweat extract in 2 dilution levels (80% and 40%).

• Lösungsmittelkontrolle: Schweißlösung (pH 7,3-7,4);
• Positivkontrolle: 12% DMSO in Schweißlösung;
• Negativkontrolle: Kulturmedium.

Evaluation: After the cells had been incubated, formazan formation was measured using the MTT test as a measure of vitality 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.

The percentage vitality was calculated using the following formula: $$\%\mathrm{vitality}\ddot{\mathrm{a}}\mathrm{t}=\mathrm{100}\times \left[\left(\mathrm{OD}\mathrm{570}\mathrm{nm\; sample}-\mathrm{OD}\mathrm{570}\mathrm{nm\; blank}\right)/\left(\mathrm{OD}\mathrm{570}\mathrm{nm\; control}-\mathrm{OD}\mathrm{570}\mathrm{nm\; blank}\right)\right]$$

• Positivkontrolle: 2% Vitalität
• Negativkontrolle: 100% Vitalität
• Lösungsmittelkontrolle: 100% Vitalität

Testing the percentage of vitality allows skin tolerance to be assessed, with the controls showing the following vitality:

• Positive control: 2% vitality
• Negative control: 100% vitality
• Solvent control: 100% vitality

Evaluation criteria: A determined vitality of over 70% compared to the solvent control shows that the sample is not toxic for cells. The exemplary textile fabrics according to the invention comprising 95% bamboo viscose and 5% elastane showed a vitality in the 80% dilution stage of 100% and a vitality in the 40% dilution stage of 98%. Since the compatibility of a material is given when the vitality of the cells is over 70% compared to the solvent control, the tolerance of the exemplary textile fabrics according to the invention is given, so that the exemplary textile fabric according to the invention is considered skin-friendly.

Example 3 Investigation of the sensitizing potential of the textile fabrics according to the invention

The sensitizing potential of the textile fabrics according to the invention comprising 95% bamboo viscose and 5% elastane (270 g/m ² ) was determined 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 using an in vitro screening test against U937 histiocytes (immune cells) in RPMO with 25 mM HEPES, 2% L-glutamine and 10% FCS as culture medium.

The extraction process was carried out by incubating the test substance with acidic sweat solution according to the standard 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 original sweat extract.

Evaluation: The cells react to sensitizing substances by forming specific surface markers. Antibodies that are coupled to a fluorescent dye are specifically bound to these surface markers. The percentage of cells marked in this way is determined by flow cytometry. The "Relative Fluorescence Intensity" (RFI) is calculated from this.

• Lösungsmittelkontrolle: Schweißlösung (pH 7,3-7,4);
• Positivkontrolle: 1 µg/ml DNCB in Schweißlösung;
• Negativkontrolle: 0,2% DMSO in Schweißlösung.

controls:

• 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.

The relative fluorescence intensity is calculated using the following formula: $$\mathrm{RFI}=\left[\left(\mathrm{MFI\; chem}\mathrm{.}\mathrm{treated\; cells}\right)-\left(\mathrm{MFI\; chem}\mathrm{.}\mathrm{treated\; isotype\; control\; cells}\right)\right]/\left[\left(\mathrm{MFI\; with\; welding\; hole}\ddot{\mathrm{O}}\mathrm{sung\; treated\; cells}\right)-\left(\mathrm{MFI\; with\; sweat}\ddot{\mathrm{O}}\mathrm{solution-treated\; isotype\; control\; cells}\right)\right]$$

For the purposes of this invention, the abbreviations designate: RFI=relative fluorescence intensity and MFI=mean fluorescence intensity.

Testing for sensitization allows the risk potential of the tested substances to be assessed to trigger allergies.

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

Under the specified conditions, the sweat extract of the textile fabrics according to the invention shows a biological activity in this test. A sensitization potential of the exemplary textile fabrics according to the invention was not determined (RFI < 120).
