Description

The present invention relates to a component system for dyeing of denim fabrics, which contain a dye component and a second, removing excess dye Component includes.

Jeans fabrics are special that colored warp threads are used for jeans fabrics, whereas the weft threads used not colored Cotton. This peculiarity of the jeans fabric caused Problems with a subsequent coloring of denim fabrics. Because of the known products for re-dyeing / dyeing Jeans fabrics after the dyeing process a top unsatisfactory result achieved because of the well-known colorants Warp and weft threads in denim fabrics be colored evenly, so that in the re-colored or newly colored Jeans fabric the real thing Jeans character has been lost. The result is a simple one and cheap looking product.

To achieve the best possible true color effect To achieve this, reactive dyes are used. These reactive dyes are characterized by the fact that over reactive Groups with functional groups of the respective fibers, for example Cotton, covalent bonds are formed. This will make it a solid Connection of the dye achieved with the fiber in question. The The result is real, highly brilliant textile dyeing. Become jeans fabrics with reactive dyes post-dyed or dyed as textile dyes is the achievable result depending on the amount of textile color used. If too much textile color based on reactive dyes, added, the jeans fabric is dyed evenly, and the jeans effect is gone lost. However, if too little textile dye, based on reactive dyes, dosed, almost no effect can be seen.

Because of the effect described above is therefore a coloring with textile colors, which achieve a real color, in use for the Customers, usually the end user, are extremely problematic, since an exact dosage of the amount of textile dye to be used for dyeing must be made. This complicates the use of such textile colors, and the acceptance among the addressed end users is corresponding low.

To make matters worse, that itself distinguish the jeans fabric from each other, so that an exact Prediction of the amount to be added by the manufacturer can hardly be made as a recommendation to the end user.

The present invention lies now based on the task of making a component system available make, which does not have the aforementioned disadvantages.

According to the invention, this object is achieved by a component system for dyeing of denim fabrics comprising a dye component and one the second, removing excess dye Component, wherein the dye component is from about 85 to about 99.5 % By weight, preferably about 90 to about 99.5% by weight, more preferably about 95 to about 99% by weight of a salt, about 0.2 to about 14.5% by weight, preferably about 0.5 to about 5% by weight of a dedusting agent and about 0.2 to about 8% by weight, preferably about 0.5 to about 5% by weight preferably comprises from about 0.5 to about 3% by weight of a dye, and wherein the second component is preferably about 80 to about 99% by weight about 90% to about 99% by weight of a salt and about 0.2 to about 15% by weight, preferably about 0.5 to about 5% by weight, more preferably about 0.5 to about 4% by weight of a polyvinyl polymer, wherein the weight percentages are based on the total amount of respective components, and being the ratio of the amount added (in% by weight) of the dye to that of the polyvinyl polymer in is in a range from about 1:10 to about 5: 1. The second includes Component preferably up to about 10% by weight of a surfactant, further preferably about 0.2 to about 3% by weight.

The ratio is preferably amount of the dye added to that of the polyvinyl polymer in a range from about 1: 6 to about 4: 1, more preferably 1: 6 up to about 1: 1. The dye is more preferably a noun dye.

A noun dye (also direct dye is a generally water-soluble dye, which in substance on the fiber concerned. Here, too the one to be colored Fiber does not have covalent bonds as in the case of reactive dyes received, rather the dye binds to the respective fiber due to electrostatic, steric or other interactions between the fiber and the dye molecules.

The component system according to the invention has the huge Advantage that a exact dosage of the dye to be added or the dye component in contrast to known dyes is no longer necessary. No matter whether a single pair of jeans or a pair of jeans washed with a denim jacket and other denim fabrics, can always be the same amount of the dye component and the second Component are used, in which case a coloring effect is achieved by which the jeans character of the to be dyed Tissue is largely preserved. The component system according to the invention is therefore extremely simple and versatile in different ways Apply denim fabrics.

By in the component system according to the invention the ratio of the quantity added has been set of the dye of the dye component to that of the polyvinyl polymer the second component enables jeans fabrics to be colored, through which the jeans effect is preserved. The polyvinyl polymer can with the given conditions one on the colored one Remove any excess dye from the textile, because a strong complex compound with the polyvinyl polymer the added dyes is considered. This will existing dye excess very easy and thorough from the colored one Peeled off denim. At the same time, the ratio mentioned also ensures that not excessively Dye is peeled off. Surprisingly, it has been shown that with the component system according to the invention very color-fast colored Jeans fabrics can be obtained an effect that the expert actually only when using Reactive dyes would have expected. This is probably due to the fact that a relative small amount of dyes is used, which has a high affinity for the to be colored Have jeans fabric. About that dyed jeans fabrics can also be obtained with the component system according to the invention, which are extremely high values for water fastness, wash fastness at 40 ° C and perspiration fastness exhibit.

The polyvinyl polymer is preferred the second component is a homopolymer, in particular polyvinylpyridine N-oxide, and / or a copolymer, more preferably a copolymer selected from monomers from a group comprising 1-vinylimidazole and / or 1-vinyl-2-pyrrolidone. Such polyvinyl copolymers advantageously take the whole Excess color, which on the dyed denim is, but not so complete that the entire applied Textile color completely is removed. Polyvinyl copolymers of the substance class mentioned result in colored Jeans fabrics that have a jeans character even after dyeing.

The second component preferably has of the component system less than about 2% by weight of the polyvinyl polymer on. Such amounts of the polyvinyl polymer in the second component know especially considering of the relationship the same to the amount of dye added in the dye component excellent properties especially in terms of achievement of a denim-typical coloring character on. Furthermore, those with polyvinyl polymers have the aforementioned Lot of dyed jeans fabrics in particular a very high fastness to washing, i.e. even after repeated Washing is not a strong discoloration determine.

Furthermore, the present concerns Invention the use of the component system according to the invention for coloring of denim fabrics.

The above and other advantages The present invention is illustrated by the following examples clarified.

Original jeans from various brand manufacturers were under different conditions in different Washing machines with the following dye components or second Components treated:

dye component A

The in the dye component A Dyes used are reactive dyes. The dye settles from 16.67 wt% red RB gran. 133, 74.07% by weight navy blue GG gran. 133 and 9.26% by weight brilliant blue R spec. together, the weight percent are each based on the total amount of the dye. The single ones mentioned dye constituents contained in the dye from DyStar Textilfarben GmbH & Co., Leverkusen, Germany.

0.35 g of the one defined above Dye were together with 675 g of sodium chloride as a salt and 75 g metasilicate (manufacturer: SILMACO N.V., Lanaken, Belgium) as Alkali fixer and 0.25 g Pluriol E 400 (BASF Aktiengesellschaft, Ludwigshafen), a polyethylene glycol, as a dedusting agent. The dye component A thus obtained served as a reference substance.

dye component B

The dye of the dye component B was composed of 4.68% by weight Sirius Blau S-BRR, 4.08% by weight Telon Marine AMF, 4.68% Sirius Black OB-V, 1.20% Isolan Black 2S-LDN, 1.20% Sirius Rubin K-2BL, 0.30% Telon Yellow A3RL and 83.86 % By weight sodium sulfate. The aforementioned dyes are all substantive dyes and come from the company DyStar Textilfarben GmbH & Co., Leverkusen, Germany. 4 g of this dye mixture were mixed with 145 g of sodium chloride (BASF Aktiengesellschaft, Ludwigshafen, Germany) and 1 g Pluriol E 400 mixed.

Second component

Mixtures of 0.6 g of Ninol LMP (company STEPAN EURO PE, Voreppe, France), a surfactant based on alkylolamides and alkylolamines, and 0.9 Marlon ARL (Brenntag GmbH, Mülheim, Germany), a surfactant based on mixtures of benzenesulfonic acids with C ₁₀ -C ₁₃ alkyl derivatives and sodium toluenesulfonate (Examples A1, A2, B1 and B2), or 1.5 g of Ninol LMP and 2.25 g of Marlon ARL (Example C1) with 1 g of Sokalan HP 56 granules (BASF Aktiengesellschaft, Ludwigshafen, Germany) (sample B1), 10 g of Sokalan HP 56 granules (example B2), 20 g of Sokalan HP 56 granules (examples A1 and C1) and 5 g of Soka-lan HP 56 granules (example A2). Sokalan HP 56 granulate is a polyvinylpyrrolidone obtained from 1-vinylimidazole and 1-vinyl-2-pyrrolidone. These mixtures were made up to an amount of 150 g with sodium chloride as a salt.

With the aforementioned mixtures different jeans fabrics dyed:

Example A

Here was an original pair of jeans Colored "Revils". First of all in the example A0 as standard pattern an original jeans of the brand "Revils" at 40 ° C with a commercial Heavy duty detergents, for example the "Ariel" brand, Henkel KGaA, Düsseldorf, Germany. The washing took place in a washing machine of the brand "AEG 70529", company AEG-Hausgeräte, Nuremberg, Germany.

In example A1, the "Revils" jeans with the dye component B at 40 ° C colored, being subsequently at 40 ° C was washed with the second component, consisting of 20 g Sokalan HP 56 granules, 0.6 g Ninol LMP, 0.9 g Marlon ARL, where filled up this mixture was added to an amount of 150 g by sodium chloride as the salt.

In example A2 was again with the dye component B at 40 ° C. the original jeans dyed and subsequently at 40 ° C washed with a second component according to Example A1, but instead 20 g Sokalan HP 56 granules now only 5 g Sokalan HP 56 granules was used, correspondingly more sodium chloride than salt was added.

Example B

Original jeans served as the standard here the brand "Pioneer", which at 40 ° C with a commercial Heavy duty detergent of the brand "Ariel", Procter & Gamble, Schwalbach, Germany, was washed.

In example B1, the dye component B for coloring at 40 ° C in a "Primavera" washing machine from Miele & Cie GmbH & Co KG, Gütersloh, Germany then at Washed at 40 ° C with a mixture of 0.6 g Ninol LMP, 0.9 g Marlon ARL, 1 g Sokalan HP 56 granules, again filled up to an amount of 150 g with sodium chloride as the salt, second Component.

In Example B2 procedure, but 10 g of Sokalan HP 56 granules were used here and correspondingly less sodium chloride than salt added.

Example C

Example C0 was used as standard, namely an original pair of jeans from the brand "Levi Strauss ", washed by 40 ° C with a commercial one Heavy duty detergent of the brand "Ariel", Procter & Gamble, Schwalbach, Germany.

In a washing machine "W 935" from Miele & Cie GmbH & Co KG, Gütersloh, Germany, the dye component B was in Example C1 coloring the original "Levi Strauss jeans used at 40 ° C being subsequently at 40 ° C was washed with a mixture of 20 g of Sokalan HP 56 granules, 1.5 g of ninol LMP and 2.25 g Marlon ARL, each made up to 150 g by a corresponding one Add sodium chloride as a salt.

In example C2 was at 40 ° C in one Washing machine "W 935 "from Miele & Cie GmbH & Co KG, Gütersloh, Germany, using the dye component A at 40 ° C the original jeans colored and subsequently at 40 ° C washed with a commercially available Detergent of the "Ariel" brand, Procter & Gamble, Schwalbach, Germany.

In example C3 was in a washing machine the brand "Primavera" from Miele & Cie GmbH & Co KG, Gütersloh, Germany, the dye component B for dyeing at 40 ° C of the original jeans used, afterwards at 40 ° C was washed with a commercial detergent "Ariel" brand from Procter & Gamble, Schwalbach, Germany.

The different jeans washed and dyed in this way were checked for water fastness according to DIN EN ISO 105-E01, wash fastness according to DIN EN ISO 105-C06 at 40 ° C and sweat fastness according to DIN ISO EN 105-E04. The results are shown in Tables 1 to 3. 1. Water justice

How to get the tables in particular 1 and 2 can be seen, the mixture C3, in which a commercially available Heavy duty detergent was used, the worst values for water justice and wash fastness at 40 ° C on. The colored one Jeans fabric according to the example C2, in which a reactive dye (dye A) was used, pointed out both for water fastness, wash fastness as well as perspiration fastness excellent values, which corresponded to the standard CO, however had the appropriately colored one Jeans have a very "cheap" look as they do was evenly colored i.e. both warp and weft Completely and were evenly colored. The colored jeans had a jeans character according to the example C2 no longer open.

All further examples A1, A2, B1, B2 and C1 showed the typical jeans character on. However, it was found that the higher the proportion of added Polyvinyl polymer in the second component was a slightly more severe discoloration of the freshly dyed Original jeans appeared. Delivered optimal results in this regard the examples A2 and B1. With regard to the verified water justice criteria, Wash fastness at 40 ° C and fastness to sweat everyone could of the examples A1, A2, B1, B2 and C1 are convincing. In every sense satisfactory results could be obtained in particular according to the example A2 can be achieved.

Has proven to be particularly advantageous highlighted a component system, which in its dye component less than 1% by weight of dedusting agent and less than 3% by weight of dye, the remaining amount being formed by salt, preferably sodium chloride and in its second component less than 0.5% by weight of surfactant and less than 4% by weight of polyvinyl polymers, the balance by Salt, preferably sodium chloride, is formed, the respective percentages by weight are based on the total amount of the respective components.
