Description

[0001] The invention relates to a composition for brightening dyed cellulosic textile fabrics in order to achieve a “used” effect.

[0002] The "used look" is a common fashion element for jeans and is achieved through a so-called "stonewashing" process. "Stonewashing" is derived from the pumice stones that are usually used to treat textiles in the wash. This process roughens the surface of the jeans in a controlled manner, thereby removing surface dye. "Stonewashing" gives the jeans the desired "used look", i.e. the jeans are faded in places and appear worn. Problems with "stonewashing" often include the unwanted deposit of dye abrasion on the textile (so-called "backstaining") and the formation of fiber balls on the surface of the textile (so-called "pilling"). "Pilling" is caused by loose fiber ends that detach from the textile, for example, after an abrasion treatment, and later develop fiber balls due to mechanical friction.

[0003] Treating jeans with pumice stone has its disadvantages. Stone particles can build up in the pockets of jeans, which then require laborious manual removal. Furthermore, pumice particles can lead to deposits in pipes and drains. Furthermore, washing machines are subject to increased wear and tear due to the use of pumice stones. Furthermore, there is a risk that the jeans will be damaged too much by the pumice stones.

[0004] In order to minimize the disadvantages of pumice, it has been proposed to partially supplement the purely mechanical process with an enzymatic treatment.

[0005] It is known from the prior art that cellulases are capable of achieving a "stonewashed" effect through enzymatic means. Published application WO 90 / 07569 A1 describes the application of an acid cellulase in combination with pumice stones.

[0006] Due to the disadvantages of pumice, published patent application DE 196 43 036 A1 proposes replacing the pumice entirely with silicon dioxide. The proposed washing process may also include cellulase. Other abrasive materials as substitutes for pumice are proposed in published patent applications EP 2 142 698 A1 (silicone polymer and aluminosilicate) and CN 1762910 A (ceramic materials consisting of magnesium clays, kaolin, feldspar, and dolomite).

[0007] A disadvantage of these processes is the application in a liquor, which generates large amounts of wastewater. For environmental protection reasons, the published patent application WO 2022 / 106072 A1 therefore proposes a process using a solid formulation consisting of a neutral cellulase, a filler, a non-ionic surfactant, an anti-backstaining agent, a dispersant, and a pH regulator. The filler is preferably selected from tectosilicate, calcium carbonate, calcium magnesium carbonate, kaolin, mica, talc, titanium dioxide, wollastonite, and / or mixtures thereof. The solid formulation is applied to the damp jeans without additional water and treated at room temperature.

[0008] Although the abrasives mentioned offer advantages over pumice, silicon dioxide (silica) and silicates (e.g., kaolin) are particularly problematic because they contain respirable crystalline silica, which can lead to silicosis. The alternatives described are also natural, non-renewable minerals that must be extracted from nature, thus contributing to resource scarcity. Furthermore, the hard materials (the Mohs hardness for silicate is approximately 7) can wear out washing machines just like pumice and lead to deposits in pipes.

[0009] In view of the disadvantages described, the task is therefore to provide an improved composition that not only leads to good "stone-washed" results, but also overcomes the disadvantages of the previously known "stone-wash" processes, i.e. is in particular harmless to health, biodegradable and sustainable.

[0010] The invention therefore relates to a composition, in particular a dry composition for the treatment of textile fabrics, containing (a) at least one cellulase, (b) at least one lignin-containing material, (c) at least one pH regulator, (d) optionally at least one surfactant and (e) where appropriate, at least one anti-backstaining agent.

[0011] The composition according to the invention may be in the form of a powder, granules, pellets or a mixture thereof.

[0012] Surprisingly, it was found that the composition according to the invention produces an improved “stone-washed” effect with less backstaining and comparable pilling compared to the prior art.

[0013] These improvements are particularly surprising, since the skilled person had to assume that the cellulases would be bound and thus inhibited in the presence of lignin-containing materials (Pan Xj, Role of functional groups in lignin inhibition of enzymatic hydrolysis of cellulose to glucose, J. Biobased Mater. Bioenergy 2008, 2: 25-32). At the very least, competition between the cellulosic substrate and the lignin-containing material had to be assumed, which would have reduced the "stonewashed" effect.

[0014] The lignin-containing material is harmless to health and the environment and comes from biodegradable waste products, so no resources are wasted.

[0015] Preferably, the composition according to the invention, in particular the dry composition, is used to treat textile fabrics selected from natural cellulosic fibers such as cotton, linen, hemp, jute and ramie, artificial cellulosic fibers such as viscose, cellulose acetate, cellulose triacetate, rayon, cupro, modal, lyocell and mixtures thereof, optionally with other synthetic fibers.

[0016] In particular, a neutral cellulase is used, i.e., a cellulase that has a maximum activity in the neutral range (especially at a pH of 6.5-7.5). Suitable cellulases can be endo-1,4-β-glucanases, exo-1,4-β-glucanases, β-glucosidases, and mixtures thereof, even more preferably endo-1,4-β-glucanases. The enzyme activity of the cellulase(s) used is preferably at least 300 U / g, more preferably 1,000-10,000 U / g, and most preferably 5,000-9,000 U / g. In a particularly preferred embodiment, a cellulase according to CAS number 9012-54-8 is used.

[0017] The cellulase or component a) may be in powder form or as granules or pellets, preferably as granules.

[0018] In a preferred embodiment, the proportion of component (a) is 0.01-5 wt.%, more preferably 0.05-2 wt.% and most preferably 0.1-1 wt.% based on the total dry composition.

[0019] Accordingly, the proportion of component (a) is 0.01-4 wt.%, more preferably 0.04-1.6 wt.% and most preferably 0.1-0.8 wt.% based on the total composition.

[0020] The lignin-containing material (b) preferably originates from biomass. The lignin-containing material of component (b) is preferably abrasive and / or sharp-edged. The lignin-containing material (b) is characterized in particular by a high lignin content. In a preferred embodiment, the lignin-containing material (b) has 16-45 wt.%, more preferably 25-45 wt.%, even more preferably 30-45 wt.% lignin, based on the total mass of component (b).

[0021] In a preferred embodiment, the lignin-containing material (b) contains 30-45 wt.% cellulose, more preferably 34-43 wt.% cellulose based on the total mass of component (b).

[0022] Finally, the lignin-containing material (b) preferably comprises 20-30 wt.%, more preferably 22-29 wt.%, of hemicellulose based on the total mass of component (b). In a particularly preferred embodiment, the lignin-containing material (b) contains: 16-45 wt%, more preferably 25-45 wt%, lignin, 30-45 wt%, more preferably 34-43 wt%, cellulose and 20-30 wt.%, more preferably 22-29 wt.%, hemicellulose, each based on the total mass of component (b).

[0023] In a preferred embodiment, the lignin-containing material of component (b) is not a natural or synthetic fiber having a lignin content of ≤ 5 wt.% based on the total mass of the fiber. In one embodiment, the lignin-containing material (b) is different from the textile fabric. In particular, the lignin-containing material of component (b) does not contain natural cellulosic fibers, such as cotton, linen, hemp, jute, and ramie, artificial cellulosic fibers, such as viscose, cellulose acetate, cellulose triacetate, rayon, cupro, modal, lyocell, and mixtures thereof. In particular, the lignin-containing material (b) is also not a soap nut.

[0024] The proportion of component (b) is preferably in the range of 5-99 wt.%, more preferably 10-20 wt.%, based on the total mass of the dry composition.

[0025] The proportion of component (b) is preferably in the range of 4-80 wt.%, more preferably 8-30 wt.%, based on the total mass of the composition.

[0026] The lignin-containing material of component (b) is preferably characterized by an average particle diameter of 100-250 µm, more preferably 120-200 µm, and most preferably 140-170 µm. Particles with a larger or smaller average diameter exhibit a significantly lower "stonewashed" effect.

[0027] The mean particle diameter is measured according to DIN 66165.

[0028] The appropriate particle size of the lignin-containing material can be achieved using conventional grinding methods, followed by sieving if necessary. Suitable grinding methods include treatment with impact mills, hammer mills, pin mills, fine impact mills, possibly with a pendulum or plate impact mill, a condux mill, or a roller mill.

[0029] The lignin-containing material (b) preferably has a Mohs hardness in the range of 1.5-5.5, more preferably 2-4, measured according to DIN EN 101.

[0030] The materials therefore have a suitable hardness, which on the one hand ensures the abrasive effect of the material, and on the other hand does not significantly attack the machine parts during “stone-washing”.

[0031] In a particularly preferred embodiment, the lignin-containing material (b) is obtained from nutshells and / or kernel shells.

[0032] In a particularly preferred embodiment, the lignin-containing material (b) is obtained from nutshells. Suitable nutshells are walnut, hazelnut, almond, coconut, pistachio, macadamia, pecan, or mixtures thereof. Kernel shells are preferably kernel shells from stone fruits, especially olives, apricots, peaches, cherries, and plums, pines, palm fruits, jojoba fruits, cocoa beans, or mixtures thereof.

[0033] The lignin-containing material (b) preferably contains no seeds or nuts. The components of seeds and nuts, especially the fats, adversely affect stonewashing.

[0034] The lignin-containing material (b) preferably contains a maximum of 3 wt.%, more preferably 0.01-3 wt.%, and even more preferably 1-2 wt.%, of petroleum ether-soluble components based on the total mass of component (b). The mass of the petroleum ether-soluble components is determined in accordance with ISO 734.

[0035] The kernel and / or nut shells preferably contain other ingredients. Accordingly, the lignin-containing materials (b) further comprise mono- and / or polysaccharides, more preferably sucrose, glucose, xylose, mannitol, and / or myoinositol. Without being bound to any theory, the mono- or polysaccharides, in particular sucrose, glucose, xylose, mannitol, and myoinositol, can act as cellulase activators. Accordingly, the abrasive lignin-containing materials of component (b) are particularly suitable for the composition according to the invention.

[0036] The lignin-containing material (b) preferably has a bulk density of 300-700 kg / m 3 , more preferably 400-600 kg / m 3 . The bulk density is determined in accordance with DIN ISO EN 60.

[0037] The composition according to the invention contains at least one pH regulator. The pH regulator ensures the pH at which the cellulase exhibits its highest activity. Suitable pH regulators are known in the art and are selected from a water-soluble inorganic and / or organic salt, more preferably a phosphate, sulfate, carbonate, citrate, or acetate salt. Preferably, the pH regulator (c) is selected from the alkali metal salt of ortho-, di-, or triphosphoric acid, sulfuric acid, carbonic acid, citric acid, and / or acetic acid. Preferably, the pH regulator (c) is selected from the alkali metal salt of ortho-, di- or triphosphoric acid, sulfuric acid, carbonic acid, citric acid, acetic acid, adipic acid and / or tris(hydroxymethyl)aminomethane (TRIS) buffer, 3-(N-morpholino)propanesulfonic acid (MOPS) buffer and / or 2-(4-(2-hydroxyethyl)-1-piperazinyl)ethanesulfonic acid (HEPES) buffer.

[0038] Component (c) is preferably a mixture of alkali salts of ortho-, di- or triphosphoric acid with alkali salts of sulfuric acid, in particular a mixture of sodium phosphate and sodium sulfate.

[0039] The pH regulator of component (c) may be in the range of 1-80 wt%, more preferably 10-70 wt% and most preferably 40-70 wt% based on the total mass of the dry composition.

[0040] The pH regulator of component (c) may be in the range of 1-60 wt%, more preferably 10-40 wt% and most preferably 30-40 wt% based on the total mass of the composition.

[0041] Corresponding to the activity maximum of the neutral cellulase, the composition according to the invention preferably has a pH of 5-8, more preferably a pH of 6.5-7.5, measured as a 1% aqueous solution of the composition at room temperature.

[0042] The composition may further contain at least one surfactant (d). The surfactant is preferably a nonionic surfactant and more preferably a polyalkoxylated fatty alcohol, polyalkoxylated fatty amine, polyalkoxylated fatty acid, polyalkoxylated fatty acid amide, polyalkoxylated mono-, di- or triglyceride, polyalkoxylated alkylphenol, fatty acid alkanolamide, copolymer of ethylene oxide and propylene oxide, polyalkoxylated polyol, esters of fatty acids with polyalkoxylated polyols, amine oxide or amidoamine oxide. In a preferred embodiment, component (d) is selected from the group consisting of alkoxylated C9-C 25 -fatty alcohols, alkoxylated C9- 25 -fatty acid amines, alkoxylated C9-C 25 -fatty acid amides, C8-C alkoxylated at the carboxylate function 25 -fatty acids, alkoxylated C8-C 25 -fatty acid esters, alkoxylated C8-C 25 -alkylphenols and alkoxylated mono-, di- or triglycerides of C8-C 25-fatty acids and / or their esterification products with C8-C 25 -fatty acids or trialkylphenyl polyalkoxylene or a block polymer, e.g., poly(ethylene oxide-co-propylene oxide), or fatty alcohol-poly(ethylene oxide-co-propylene oxide), and mixtures thereof. The number of alkoxylene groups in the non-ionic surfactant is at least 4, preferably 8-100, more preferably 10-85, and most preferably 20-80 repeating units. The alkyl groups can each independently be branched or straight-chain, saturated or unsaturated.

[0043] Preferred nonionic surfactants (d) are alkoxylated C 12 -C 18 -Fatty alcohols with 50-100 repeating units of the alkoxylene groups.

[0044] Suitable non-ionic surfactants preferably have an HLB value of 9 to 11, 11 to 14 or > 14, in particular > 14.

[0045] The HLB value describes the hydrophilic and lipophilic fraction of the non-ionic surfactants (WC Griffin: Classification of surface active agents by HLB. In: J. Soc. Cosmet. Chem. 1, 1949, pp. 311-326).

[0046] Component (d) simultaneously supports the dispersion of the lignin-containing materials and the wetting of the textile fabric to be treated with the components of the composition.

[0047] The surfactant of component (d) may constitute 0-40 wt%, preferably 5-30 wt%, most preferably 10-20 wt%, based on the total mass of the dry composition.

[0048] The surfactant of component (d) may comprise 0-30 wt%, preferably 4-20 wt%, most preferably 10-15 wt%, based on the total mass of the composition.

[0049] Stonewashing involves intentionally removing dye particles from textile fabrics. Anti-backstaining agents are typically used to prevent the dye particles from settling in other areas, particularly where they are not desired, such as uncolored or differently colored areas, such as inside trouser pockets and labels. Common anti-backstaining agents of component (e) include PEG polyester, polyvinylpyrrolidone, sodium carboxymethylcellulose, hydroxypropylmethylcellulose, hydroxymethylcellulose, hydroxyethylcellulose, polyethylene glycol, or polymeric polycarboxylate. These anti-backstaining agents act as chelators for the dye particles, emulsifying and removing them, which are then rubbed off the fabric and suspended in the rinse liquid.

[0050] The anti-backstaining agent (e) is preferably present at 0-10 wt.%, preferably 1-5 wt.% and more preferably 2-3 wt.% based on the total mass of the dry composition.

[0051] The anti-backstaining agent (e) is preferably present at 0-8 wt.%, more preferably 2-3 wt.%, based on the total mass of the composition.

[0052] In particular, the composition according to the invention has a water content of ≤ 25 wt.%, preferably ≤ 10 wt.%, and most preferably 0.1-5 wt.%, based on the total mass of the composition. The water content can be determined gravimetrically or by Karl Fischer titration.

[0053] Alternatively, the composition according to the invention is preferably dry. In particular, the composition according to the invention has a water content of <5 wt.%, more preferably 0.001-2 wt.%, based on the total mass of the dry composition. The water content can be determined gravimetrically or by Karl Fischer titration.

[0054] The composition according to the invention preferably has a bulk density of 800-1,500 kg / m 3 , more preferably from 1,000-1,200 kg / m 3 .

[0055] In a further aspect, the invention relates to a kit comprising at least two separate units, wherein the first unit includes: (a) at least one cellulase, in particular selected from endo-1,4-β-glucanases, exo-1,4-β-glucanases and β-glucosidases, (d) optionally at least one surfactant, in particular a non-ionic surfactant, preferably polyalkoxylated fatty alcohol, polyalkoxylated fatty amine, polyalkoxylated fatty acid, polyalkoxylated fatty acid amide, polyalkoxylated mono-, di- or triglyceride, polyalkoxylated alkylphenol, fatty acid alkanolamide, copolymer of ethylene oxide and propylene oxide, polyalkoxylated polyol, esters of fatty acids with polyalkoxylated polyols, amine oxide or amidoamine oxide, and (e) optionally at least one anti-backstaining agent, in particular selected from PEG polyester, polyvinylpyrrolidone, sodium carboxymethylcellulose, hydroxypropylmethylcellulose, hydroxymethylcellulose, hydroxyethylcellulose, polyethylene glycol and polymeric polycarboxylate; and the second unit includes: (b) at least one lignin-containing material, which preferably contains 16-45 wt.% lignin based on the total mass of component (b), (c) at least one pH regulator, in particular selected from a water-soluble inorganic salt and / or water-soluble organic salt, (d) optionally at least one surfactant, in particular a non-ionic surfactant, preferably polyalkoxylated fatty alcohol, polyalkoxylated fatty amine, polyalkoxylated fatty acid, polyalkoxylated fatty acid amide, polyalkoxylated mono-, di- or triglyceride, polyalkoxylated alkylphenol, fatty acid alkanolamide, copolymer of ethylene oxide and propylene oxide, polyalkoxylated polyol, esters of fatty acids with polyalkoxylated polyols, amine oxide or amidoamine oxide, and (e) optionally at least one anti-backstaining agent, in particular selected from PEG polyester, polyvinylpyrrolidone, sodium carboxymethylcellulose, hydroxypropylmethylcellulose, hydroxymethylcellulose, hydroxyethylcellulose, polyethylene glycol and polymeric polycarboxylate; or the first unit includes: (a) at least one cellulase, in particular selected from endo-1,4-β-glucanases, exo-1,4-β-glucanases and β-glucosidases, (c) at least one pH regulator, in particular selected from a water-soluble inorganic salt and / or water-soluble organic salt, (d) optionally at least one surfactant, in particular a non-ionic surfactant, preferably polyalkoxylated fatty alcohol, polyalkoxylated fatty amine, polyalkoxylated fatty acid, polyalkoxylated fatty acid amide, polyalkoxylated mono-, di- or triglyceride, polyalkoxylated alkylphenol, fatty acid alkanolamide, copolymer of ethylene oxide and propylene oxide, polyalkoxylated polyol, esters of fatty acids with polyalkoxylated polyols, amine oxide or amidoamine oxide, and (e) optionally at least one anti-backstaining agent, in particular selected from PEG polyester, polyvinylpyrrolidone, sodium carboxymethylcellulose, hydroxypropylmethylcellulose, hydroxymethylcellulose, hydroxyethylcellulose, polyethylene glycol and polymeric polycarboxylate; and the second unit includes: (b) at least one lignin-containing material, which preferably contains 16-45 wt.% lignin based on the total mass of component (b), (d) optionally at least one surfactant, in particular a non-ionic surfactant, preferably polyalkoxylated fatty alcohol, polyalkoxylated fatty amine, polyalkoxylated fatty acid, polyalkoxylated fatty acid amide, polyalkoxylated mono-, di- or triglyceride, polyalkoxylated alkylphenol, fatty acid alkanolamide, copolymer of ethylene oxide and propylene oxide, polyalkoxylated polyol, esters of fatty acids with polyalkoxylated polyols, amine oxide or amidoamine oxide, and (e) optionally at least one anti-backstaining agent, in particular selected from PEG polyester, polyvinylpyrrolidone, sodium carboxymethylcellulose, hydroxypropylmethylcellulose, hydroxymethylcellulose, hydroxyethylcellulose, polyethylene glycol and polymeric polycarboxylate.

[0056] The kit contains components (a)-(e) preferably in dry form, i.e. with a water content of < 5 wt.%, more preferably 0.001-2 wt.%, based on the total mass of the components.

[0057] Components (a)-(e) of the kit correspond to the respective components of the (dry) composition according to the invention. The combined components of the first unit and the second unit result in the composition according to the invention. The above-mentioned features of the composition according to the invention apply accordingly to the entirety of the respective components in the first and second units of the kit.

[0058] In one embodiment of the present invention, the composition or kit according to the invention - as described above - can be used for the treatment of textile fabrics (see above), in particular for brightening dyed textile fabrics.

[0059] The composition or kit according to the invention is ideally suited for stonewashing applications, giving textile fabrics and textiles a "used look." Surprisingly, the backstaining effect is also less pronounced compared to conventional stonewashing preparations. Without being bound by any theory, it is assumed that the inventive combination of cellulase (a) and the lignin-containing material (b) act synergistically with each other.

[0060] In a further aspect, the present invention relates to a method for treating textile fabrics, comprising the steps (i) Providing a water-moist textile fabric, (ii) adding the composition or kit according to the invention, (iii) moving the mixture obtained after step (ii) in a container, (iv) washing the textile fabric obtained after step (iii) and (v) isolating and, if necessary, drying the textile fabric obtained after step (iv).

[0061] It has surprisingly been found that the composition according to the invention can be applied to the moist textile fabric in the dry and / or free-flowing state without the need to form an aqueous liquor.

[0062] In the case of a kit, in step (ii) either the first unit is applied to the moist textile fabric before the second unit or the second unit is applied before the first unit.

[0063] Preferably, the textile fabric in step (i) has a water content of 70-100 wt.% water, more preferably 90-100 wt.%, based on the dry weight of the textile fabric. The water content is measured according to DIN 54201.

[0064] In an alternative embodiment, the textile fabric in step (i) has a water content of 70-400 wt.% water, more preferably 200-300 wt.% water, based on the dry weight of the textile fabric. The water content is measured according to DIN 54201.

[0065] The textile fabric is preferably dyed. Common dyes are sulfur, reactive, direct, VAT, pigment, natural dyes, or mixtures thereof. Textile fabrics dyed with pigment dyes, especially indigo-dyed textile fabrics, are particularly preferred.

[0066] The weight ratio of dry textile fabric to composition according to the invention in step (ii) is preferably 100:0.5-10, more preferably 100:1-10, more preferably 100:0.5-5, more preferably 100:1-5, more preferably 100:2-5.

[0067] Step (iii) is preferably carried out in a washing drum. Conventional washing drums are known to the person skilled in the art and can be installed in household washing machines, industrial washing machines, etc. Step (iii) is preferably carried out at 20-60, more preferably 20-40 rpm. Typically, step (iii) is carried out for 10-60 minutes, preferably 35-45 minutes. In particular, step (iii) is carried out at room temperature (20-25 °C). Higher temperatures up to 60 °C (such as 15-60 °C or 20-30 °C) can be set. Alternatively, step (iii) is carried out in particular at 15-25 °C. Higher temperatures up to 60 °C (such as 20-60 °C or 30-40 °C) can be set. The deactivation temperature of the cellulase must be taken into account when setting the temperature.

[0068] After step (iii), the resulting textile fabric is washed. Step (iv) preferably takes place directly in the container used in step (iii). Step (iv) is usually carried out by adding water (tap water or distilled water), to which commercially available detergents, fabric softeners, surfactants, etc. may be added.

[0069] The washing process in step (iv) is preferably repeated until the proportion of component (b) has been reduced by at least 90 percentage points, more preferably 95 percentage points, compared to the proportion of component (b) in step (ii).

[0070] The washing process is repeated 1-5 times at a liquor ratio of 1:5 - 1:7, ie for a pair of jeans with a dry weight of 556 g, 2780 g - 3892 g of water, especially tap water, are used.

[0071] In step (v), the textile fabric obtained after step (iv) is usually first spun and, if necessary, dried.

[0072] Spinning is preferably carried out for 2-10 minutes, more preferably 3-5 minutes, at preferably 100-1000 revolutions per minute, more preferably 300-500 revolutions per minute.

[0073] Drying takes place in commercially available industrial or household dryers. Those skilled in the art are familiar with appropriate dryers such as condensation, ventilation, or heat-pump dryers, as well as stenters. Drying is preferably carried out at 20–90 °C, more preferably at 30–75 °C.

[0074] The present invention is illustrated by the following examples: ExamplesExample 1 (Comparison with silicate abrasive)

[0075] A preparation A according to the invention was compared with a prior art silicate-containing composition B. The respective compositions and their properties can be found in Table 1.

[0076] A pair of brand-new denim jeans (indigo- and sulfur-dyed cotton fabric) weighing approximately 556 g were placed in a TONELLO G1 Model 70 L1 Ecofree drum washing machine (capacity 70 l) with 1670 g of water and excess water was removed (pumped out).

[0077] 55 g of composition A and B were then added to the wet jeans in dry form and dried at 20°C for 30 min at 24 rpm. -1 treated with reversal of the direction of rotation every two minutes.

[0078] The jeans were then rinsed for 1 minute at 20°C in 2780 g of tap water each. The water was then spun in a TONELLO Hydro 12 spin dryer for 5 minutes at 300 rpm. -1 and then completely removed in a dryer “TONELLO G1 Model TD 25 E” at 70°C for approx. 40 minutes.

[0079] The change in brightness was examined on the outside of the right trouser leg (abrasive effect) and on the inside right pocket (backstaining effect). The fabric was also visually inspected for pilling.

[0080] The results of Jeans A (Composition A) and Jeans B (Composition B) are summarized in Table 2. Table 2: Results of the stone-washing treatment Result Jeans A Jeans B (comparison) Color intensity [%] 96,9 100 Backstaining on the inside pocketColor intensity [%] 84,5 100 Backstaining on the inside pocket[DL] -0,5 0

[0081] “DL” refers to the change in brightness or darkness.

[0082] “Color intensity” and “color depth” each refer to color strength and are used synonymously.

[0083] In the color measurement according to Example 1, the jeans treated with a composition according to the state of the art were set as the standard with 100% color depth.

[0084] It was found that the bleaching effect of the composition according to the invention was 3.1% higher compared to jeans treated with the prior art composition ( Fig. ).

[0085] At the same time, the backstaining on the inside pocket was 0.52 points lower, i.e. the inside pocket of jeans A is brighter than the inside pocket of the comparison jeans B.

[0086] In further experiments, a brightening of 6.5% and more was observed.

[0087] No difference was observed in pilling, ie the formation of fiber knots. The inventive composition A ( Fig.has therefore not put more strain on the textile than composition B ( Fig. .

[0088] Further experiments showed even fewer loose fiber ends after treatment with Composition A compared to treatment with Composition B. Example 2 (Measurement of color intensity)

[0089] Color intensity was determined using a Datacolor 600 colorimeter with Datacolor TOOLS software in the measurement range between 380 and 700 nm. A pair of jeans with 100% color depth was used as the standard. Color measurements were performed according to DIN 5033-1 and DIN 6176. Example 3 (Backstaining)

[0090] In order to investigate backstaining, i.e. the staining of undyed parts such as the inside pockets, a pair of jeans with the compositions A and CE (see Table 1) was treated as in Example 1 and the results of the stonewashing (Table 3) were compared. Table 3: Backstaining of Jeans A and CE (Standard: Jeans C) Result Jeans A Jeans C(Comparison)Standard Jeans D (comparison) Jeans E (comparison) Backstaining on the inside pocketColor intensity [%] 211,6 100 163,8 205,0 Backstaining on the inside pocket[DL] 2,19 0 0,38 1,95

[0091] The additive (theoretical) backstaining from Jeans D and Jeans E (0.38+1.95 = 2.33 points) is more pronounced than in Jeans A (2.19 points), which suggests a synergistic effect of cellulase and lignin-containing material. Example 4 (Viscometric determination of cellulase activity)

[0092] The enzymatic degradation of soluble carboxymethylcellulose (CMC) and the associated change in viscosity can be used as evidence for the activity of cellulases. Generally, one enzyme unit is defined as the amount of enzyme needed to produce one nmol of reducing sugar such as glucose from a substrate in one second (Measurement of cellulase activities, Pure & Appl. Chem., Vol. 59, No. 2, pp. 257-268, 1987).

[0093] To check the cellulase activity in the comparable compositions of Example 1, a viscometric determination was carried out.

[0094] The measurements were carried out in a HAAKE rotational viscometer VT 500 using the software Rheowin PR= 2.97 and an MVDIN sensor at 40°C.

[0095] First, a 2.3% CMC solution was prepared by dissolving 2.3% Tylopur C33 P2 from SE Tylose GmbH&Co.KG in distilled water. The suspension was stirred for 1 hour until the CMC was completely dissolved. 40 g of the CMC solution were then mixed with 5.56 ml of acetate buffer, pH 5.0, and heated to 40°C on a hotplate. The 40°C CMC solution was transferred to the viscometer (set to 300 units / min), and the viscosity curve was recorded every 10 minutes. After the measurement, the software was used to determine the average of the measured data (blank determination).

[0096] To measure enzyme activity, 40 g of CMC solution was mixed with 5 ml of acetate buffer, pH 5.0, and heated to 40°C. The test solutions were prepared with 0.05 wt.% each of compositions A and B in acetate buffer, pH 5. After precisely adjusting the temperature, 0.3 g of neutral cellulase (8000 U / g) in acetate buffer, pH 5.0, was added, and the solution was stirred for exactly 15 seconds. The sample solution was then immediately transferred to the measuring vessel of the viscometer. Exactly 30 seconds after the enzyme addition, the measurement was started, and the viscosity curve was recorded for 10 minutes at 40°C.

[0097] After the measurement, a regression analysis (linear var) was performed using the software. The enzyme activity is determined from the following equation: Activity=F×B / E E = amount of enzyme in the test (mg) B = gradient factor from Linear var F = CMC factor = 1 × 10 8 .

[0098] The calculated activity for composition B was 3200 units, and for composition A according to the invention it was 4900 units.

[0099] Contrary to the expected reduction in activity due to the competing or inhibiting components of cellulose and / or lignin in the lignin-containing material (here: kernel shell flour), an unexpected increase in activity was observed. It can therefore be assumed that the lignin-containing material contains enzyme activators that increase cellulase activity. Example 5 (Comparison with Standard Jeans C)

[0100] A pair of brand-new denim jeans (indigo- and sulfur-dyed cotton fabric) weighing approximately 556 g were placed in a TONELLO G1 Model 70 L1 Ecofree drum washing machine (capacity 70 l) with 1670 g of water and excess water was removed (pumped out).

[0101] To the wet jeans, 55 g of the composition AG in dry form were then added and dried at 20°C for 30 min at 24 rpm -1 treated with reversal of the direction of rotation every two minutes.

[0102] The jeans were then rinsed for 1 minute at 20°C in 2780 g of tap water each. The water was then spun in a TONELLO Hydro 12 spin dryer for 5 minutes at 300 rpm. -1 and then completely removed in a dryer “TONELLO G1 Model TD 25 E” at 70°C for approx. 40 minutes.

[0103] The change in brightness on the outside of the right trouser leg (abrasive effect) and on the inside of the right pocket (backstaining effect) was examined.

[0104] Table 4 summarizes the color intensity and backstaining of the treated Jeans AG.

[0105] Jeans C treated with composition C (no lignin-containing material and no cellulase) was chosen as the standard (100% color intensity). Table 4: Results of the stone-washing treatment jeans Color intensity right trouser leg bottom [%] Color intensity right inside pocket [%] (backstaining) A 88,1 228,5 B 90,1 286,4 C 100 100 D 100 216,0 E 97,1 301,3 F 93,4 nb G 89,0 178

[0106] Jeans A shows higher whitening than Jeans B (silicate). Jeans A also shows higher whitening than Jeans D (no cellulase) and Jeans E (no lignin-containing material). Jeans A also shows higher whitening than the sum of Jeans D (no cellulase) and Jeans E (no lignin-containing material). A synergistic effect of the enzyme and lignin-containing material is therefore assumed. On the other hand, backstaining in Jeans A is comparable to that in Jeans D and reduced compared to Jeans B and E.

[0107] In Jeans F (particle diameter: 350 µm) the brightening is slightly lower than in Jeans A.

[0108] Furthermore, the results show that even at low concentrations of cellulase (Jeans G) very good results in lightening and even improved backstaining are obtained compared to Jeans A.
