Definitions
- the present invention relates to a method for dyeing or printing textile fiber materials comprising the selection of a colour or colour pattern and the preparation of the textile fabrics dyed or printed with the selected colour or colour pattern in one automated process.
- dyes from different dye classes are used, for example reactive dyes for cotton, acid dyes for silk, wool or polyamide and disperse dyes for polyester.
- the disadvantage ofthe customary procedure is that it can result in metamerism, if the dyestuffs used for the garment are not identical with the dyes ofthe selected colour standard.
- Colour standards are generally defined by design professionals who usually have no technical knowledge in the art of industrial dyeing. In some cases, this results in the definition of colour standards which cannot be dyed on certain textile fibers or the recipes for which are not technically optimized or the requisite fastness properties cannot be achieved with the colour standard defined. As a consequence all kinds of problems throughout the textile chain arise, from the designer of the fashion brand through the supplier chain to the dyeing industry, occasionally resulting in considerable financial losses.
- colour standard for example objects made from leather, plastics, metal, paper, flowers, leaves or wood etc. Frequently he will also select his colour standard from colour catalogues.
- Colour catalogues contain colour samples on a wide variety of materials, for example pigment-dyed paper or dyeings on textile samples of cotton, polyester or wool.
- the dyeings that are used to define the colour standard no account is taken ofthe fastness requirements for specific uses.
- the number of colours in the colour catalogues that are available is limited, generally from 500 to 2500 different colours.
- the dye recipes found have to be optimised technically or in respect of the required fastness properties, which can again result in problems of metamerism or colour constancy.
- An ideal colour standard does not necessarily have to be a dyeing, but can be represented by a reflectance curve.
- the reflectance curve is produced arithmetically, starting from a recipe that has been optimised technically and in respect of the in-use fastness properties and using the stored data of calibration dyeings to calculate the associated reflectance curve.
- the reflectance curve which is thus associated with an application-optimised dye recipe, is rendered visible by means of a suitable device, for example, a calibrated colour screen, and in that manner is used as the defined colour standard.
- Another aspect is to shorten the time from the idea of a colour standard to the preparation of the textile fashion fabrics.
- the problem underlying the present invention is to provide an integrated technical solution to textile professionals which accounts for the issues indicated above.
- the present invention accordingly relates to a method for dyeing or printing a textile fiber material, which comprises the steps of (i) providing a printing or dyeing apparatus capable of processing digital data; (ii) providing a digital data processing device organizing reflectance curve data which are associated with the corresponding dye recipes, wherein the reflectance curve data are generated by (a) drawing up a requirement profile for the desired dyeing, (b) selecting a group of dyes that meet the requirement profile that has been drawn up, (c) determining within the colour space the colour position of the said dyes for the desired dyeing, (d) segmenting the colour space ofthe dyes within a depth of shade plane into triangular areas according to shade, wherein the corner points ofthe triangular areas correspond to the colour position ofthe dyes in question, and the said dyes define a range of shades delimited by the triangular areas, (e) dividing the triangular areas within a depth of shade plane arithmetically into a grid in such a manner that the points of intersection ofthe grid are distributed evenly over the tri
- the problem indicated above is solved by the present invention by providing a digital catalogue of colour samples that can be reproduced easily and without metamerism on any desired textile material meeting all the desired in-use properties, the digital catalogue being equipped with a device enabling the colours organized by the digital colour catalogue to be rendered visible, and a printing or dyeing apparatus capable of processing the digital data communicated by the digital colour catalogue, and to interconnect the digital colour catalogue with the printing or dyeing apparatus in a manner that the said components form an integrated operating unit, wherein the textile fiber material is printed or dyed with the colour or colour pattern defined previously.
- a requirement profile drawn up for the desired dyeing according to Step (a) is understood to mean the definition ofthe properties or criteria that the dyed substrate is intended to fulfil.
- properties or criteria are, for example, application-related properties, such as the in-use fastness properties, for example fastness to light, chlorine, rubbing, wetting, wet rubbing, washing, water, seawater or perspiration.
- Suitable substrates are, for example, textile fibre materials, paper, plastics or metal. Further criteria in drawing up a requirement profile may also include the dyeing or printing process with which the desired dyeing is to be produced, the costs, for example of the dyes, or the pricing of the product.
- the term “dyeing” is not limited to dyeings in the customary sense, but also includes printing ofthe fabrics.
- the terms “dyeing” and “dyed textile fiber material, fabric or garment etc.” accordingly include both dyeing processes and printing processes and the coloured substrates produced by means of such processes, respectively.
- a group of dyes is selected that meet the defined requirement profile and cover the colour space as well as possible.
- a group of dyes is understood to mean, for example, three or more dyes.
- the selected dyes should also be readily combinable with one another, i.e. they should have similar affinity to the fiber, for example, when dyeing or printing cotton, they should exhibit similar substantivity and reactivity.
- the number of colours in the colour catalogue according to the invention that can be derived arithmetically is thus dependent inter alia upon the location of the selected dyes in the colour space, that is to say the number increases with the size ofthe colour space covered by the selected dyes.
- the selection ofthe dyes is advantageously made by a person skilled in the field of textile dyeing.
- colour space for the method according to the invention there can be used, for example, the known CIE Lab colour coordinate system, the lightness axis L* being replaced by the depth of shade characteristic FT.
- the advantage of that procedure is that colour positions of identical depth of shade or of identical colour strength lie in one plane ofthe colour space.
- the individual planes of the colour space are defined by the pairs of values a*, b*, which correspond to the values ofthe same name in the CIE Lab colour coordinate system.
- the a*, b* value pairs characterise the hue and the colour saturation, which are known to the person skilled in the art from the field of colour communication or colorimetrics and constitute a measure ofthe shade.
- colour saturation the specialist literature also uses the terms "chroma” or "colour brilliance”.
- a suitable depth of shade characteristic FT is, for example, the standard depth, as described, for example, in P. Rabe and O. Koch, Melliand Textilberichte 38 (1957) pages 173 to 177.
- the standard. depth can be indicated not only in the known 2/1, 1/1, 1/3, 1/6..1/12 and 1/25 depths, but also further sub-divided, for example in steps of 1/10 standard depth or smaller. Depth of shade characteristics are known to the person skilled in the art of textile dyeing.
- the colour positions of the selected dyes must be determined according to Step (c), preferably in the FTa*b* colour space, thus defining the colour space for the subsequent Steps.
- the colour positions ofthe dyes suitable for the desired dyeing are so selected that they lie on a plane of identical depth of shade, for example on a plane defined by the pairs of values a*, b*.
- the colour positions are ascertained from calibration data. If the calibration data are not known, these must first be ascertained by measurement using a commercially available colorimetric apparatus, for example a commercially available spectral photometer.
- the depth of shade characteristic FT can be ascertained, for example, from a standard depth colour chart.
- a standard depth chart or a corresponding concentration curve is produced in a manner known perse for each ofthe selected dyes, for example for the five dyes indicated in Fig. 1 which follows.
- the known depth of shade plane thus establishes the concentration of each dye to use for that depth of shade plane.
- the planes ofthe FTa*b* colour space are segmented into triangular areas according to Step (d), the corner points ofthe triangular areas corresponding to the colour position ofthe dyes that were selected for the desired dyeing in accordance with the requirement profile.
- the individual triangular areas of each depth of shade plane do not overlap.
- Each colour position in the colour space is defined by a single dye recipe, which consists, for example, of one dye when the desired colour position corresponds to the FTa*b* data of a single dye, or the recipe is a mixture of, for example, two dyes when the desired colour position lies on the usually non- straight line connecting two dyes, or the recipe is a mixture of, for example, three dyes where the ratio of those three dyes corresponds to the point of intersection of a regular grid superimposed arithmetically over the triangular areas according to Step (e).
- the dyes selected for the segmentation may themselves already be mixtures of dyes, for example a mixture of two or three dyes, that is to say, for example, that a corner point of the triangular area already corresponds to the colour position of a dye mixture. In that case also, the colour positions of the mixtures must first be ascertained from calibration data. Once the dyes for a segmentation have been selected and their calibration data have been ascertained in a manner known perse from reflectance measurements at different concentrations and thus at different depths of shade and have been stored in a computer, the segmentation ofthe FTa*b* colour space according to (d) is complete.
- Step (e) colour positions for the selected dye combination are calculated for a defined depth of shade FT, which colour positions are spaced at regular intervals across the range of shades defined by the a*,b* value pairs, that is to say the depth of shade plane is divided into a grid.
- Each grid point corresponds to a specific concentration ratio between the selected dyes and thus to a specific dye recipe.
- Fig. 1 shows the segmentation of the colour space in a depth of shade plane into three segments, the reference numerals P1 to P5 corresponding to the FTa*b* data of the selected dyes Yellow 1 (P1), Yellow 2 (P2), Red (P3), Blue 1 (P4) and Blue 2 (P5).
- Fig. 2 is a further example ofthe segmentation ofthe colour space in a depth of shade plane into twelve segments, the reference numerals P1 to P9 corresponding to the FTa*b* data of the selected dyes Yellow 1 (P1), Yellow 2 (P2), Orange 1 (P3), Orange 2 (P4), Red 1 (P5), Red 2 (P6), Blue 1 (P7), Blue 2 (P8) and Blue 3 (P9).
- the connecting lines shown in Figs. 1 and 2 are the result of mixing, in each case, two dyes in specific amounts at a predetermined depth of shade, the end points of the connecting lines corresponding to the colour positions ofthe selected dyes.
- Fig.3 shows a single segment. It is the triangular area produced by points P2, P3 and P4 in Fig. 1.
- the connecting lines between points P2, P3 and P4 are the colour positions of each of the two-component mixtures.
- the grid that has been superimposed over the entire triangular area defines colour positions of mixtures having different concentration ratios.
- Points P2, P3 and P4 define the colour positions of the respective dyes in concentrations C 2 , C 3 and C 4 .
- the grid is produced by interpolating series of mixtures between the single dyes in such a manner that the given spacing ofthe grid is obtained.
- the conversion between K/S values and reflectance values is made using the customary procedure according to Kubelka-Munk, as indicated, for example, in Colour Physics for Industry, Ed. R. McDonald, Society of Dyers and Colourists (1987), Chapter 5, 116 IT. In that procedure, the reflectance spectrum and the concentrations ofthe dyes are stored for each calculated grid point.
- Fig.4 shows a different segment made up of he dyes P10, P5 and P8.
- a grid was calculated in the same manner for the triangular area. Points P5 and P8 correspond to points P5 and P8 of Fig. 2.
- the spacings between the grid points can be preselected. The smaller the spacings, the more colour positions can be determined within a triangular area.
- the depth of shade plane defined by a triangular area corresponds, for example, to a trichromy at a depth of shade, the corner points ofthe triangular area corresponding to the colour positions selected for the trichromy. It is thus possible to regulate the number of colours per trichromy and thus also the number of colours in the catalogue.
- FIG. 5 shows the same segment as Fig.4, the difference being hat the spacing between the grid points is twice as large and thus the number of colour positions determined is reduced to 1 A
- Figs. 1 to 5 show a plane ofthe FTa*b* colour space.
- the depth of shade characteristic FT of those planes corresponds, for example, to a 2/3 standard depth.
- the reflectance curve and the amounts of dye required to dye a specific substrate in that depth of shade are known.
- the dye concentration depends, for example, on the dye itself, the depth of shade sought, the application procedure and the substrate to be dyed or printed.
- the colour positions corresponding to the points of intersection of the grid are in each case associated with a reflectance curve.
- Behind each reflectance curve lies a specific dye recipe, that is to say digital instructions for the printing or dyeing apparatus (i) as to the ratio in which the dyes that are to be combined with one another are to be mixed in order to obtain a dyeing that corresponds to the reflectance spectrum ascertained and that meets the requirement profile defined in advance according to (a).
- the catalogue which meets the requirement profile defined in advance according to (a) is made up of all the reflectance spectra calculated for all the segments in the given depths of shade.
- the reflectance spectra ascertained do not, of course, ' give the observer any impression of colour.
- implementation of an operation is required by means of which the reflectance curve is first brought into a format that enables the corresponding colour to be rendered visible using a suitable device.
- Suitable devices for visualising the reflectance curves are, for example, a colour-calibrated screen, such as a cathode ray tube apparatus or a liquid crystal flat screen, or a colour-calibrated projection apparatus. It is preferred to use a colour-calibrated screen.
- the calculated reflectance spectra are formatted in such a manner that they can be imported into a commercially available colour communication system, for example Colorite ImageMaster by Datacolor or Color Talk by GretagMacbeth.
- a commercially available colour communication system for example Colorite ImageMaster by Datacolor or Color Talk by GretagMacbeth.
- the spectra can be shown as real colours.
- the user for example a colour designer, can then look for colours in the catalogue that come closest to his colour original, which may be an idea of a colour, and that meet the previously defined requirements, and obtains the associated reflectance curves which correspond to specific dye recipes.
- the recipes obtained are communicated to the printing or dyeing apparatus capable of processing such digital data.

- the digital recipe data are communicated to the jet- or spray-dyeing apparatus to control e.g. an automatic dosing system indicated above, either directly as communicated or after being submitted to an arithmetic operation to yield a format which may be processed by the jet- or spray-dyeing apparatus, thereby dyeing polyamide-6.6 fiber material.
- the fabric is dried on line with an integrated hot air dryer at 100°C, fixed in saturated steam at 102°C and is then washed off. A dyeing having good fastness properties is obtained.
- the colour ofthe dyed fabric is identical in terms of shade, colour saturation and depth of shade to the shade Px from the catalogue that was determined arithmetically.
- the reactive dyes that, in the form ofthe free acid, correspond to the formulae indicated hereinbelow: as yellow component, the dyes of formulae (39.44), (40.17) and (40.19), as orange component, a mixture ofthe dyes of formulae (40.4), (40.14) and (40.15) and a dye of formula (39.25), as red component, the dyes of formulae (39.33) and (40.10), as blue component, the dyes of formulae (39.4) and (39.12), and a mixture of 32 % by weight of the dye of formula (39.4) and 68 % by weight of the dye of formula (39.1).
- the calibration data ofthe dyes are ascertained for the dyeing for which the colour catalogue is being produced.
- mercerised cotton satin fabric is dyed with a jet- or spray-dyeing apparatus using aqueous compositions of different concentrations of the reactive dyes specified above.
- the cotton satin fabric Prior to be dyed the cotton satin fabric is padded in a pre-treatment operation with a liquor comprising 2 g/l of a pad dyeing auxiliary comprising acrylic acid amide / acrylic acid copolymer from acrylic acid amide and acrylic acid monomer, 100 g/l of urea, 40 g/l soda ash, 100 g/l of sodium chloride, 20 g/l of sodium salt of nitrobenzene sulfonic acid and 30 g/l of a softener based on a amino functional siloxane (liquor pick-up 70%) and dried.
- the jet- or spray-dyeing apparatus may be equipped with a dispensing device as described above.
- the dyeings are measured by spectral photometry and the CIE Lab colour coordinates are determined. The depths of shade for the individual dyeings are ascertained in known manner.
- the depths of shade and the associated a* and b* data yield the colour position ofthe dyes specified above in the FTa*b* colour space.
- the colour space is then segmented within a depth of shade plane. Such segmentation is shown for a medium shade within a depth of shade plane in Fig. 2, where P1 corresponds to the colour position of the yellow dye of formula (39.44) for that dyeing; P2 corresponds to the colour position ofthe yellow dye of formula (40.19); P3 corresponds to the colour position of the orange dye mixture of the dyes of formulae (40.4), (40.14) and (40.15); P4 corresponds to the colour position of the orange dye of formula (39.25); P5 corresponds to the colour position ofthe red dye of formula (39.33); P6 corresponds to the colour position of the red dye of formula (40.10); P7 corresponds to the colour position ofthe blue dye of formula (39.12); P8 corresponds to the colour position ofthe blue dye of formula (39.4); and P9 corresponds to the colour position ofthe blue dye mixture ofthe dyes of formulae (39.1) and (39.4).
- the triangular area in that depth of shade plane is divided arithmetically into a grid.
- the triangular area corresponds to the area having the corner points P10, P5 and P8.
- the colour position P10 for the yellow dye of formula (40.17) is not shown in Fig. 2.
- the gridded triangular area is shown in Fig. 4.
- the colour positions P10, P5 and P8 of the selected dyes in that depth of shade plane correspond to 1.51 % by weight ofthe yellow dye of formula (40.17) for P10, 3.43 % by weight ofthe red dye of formula (39.33) for P5 and 2.84 % by weight ofthe blue dye of formula (39.4) for P8.
- the individual grid points on the connecting lines and within the triangular area correspond to specific concentration ratios between the dyes of formulae (40.17), (39.33) and (39.4), that is to say to a specific dye recipe, from which the corresponding reflectance curves are calculated.
- the reflectance curves are stored in a data base and formatted in such a manner that they can be imported into a commercially available colour communication system.
- the stored data are rendered visible as colours using a calibrated colour screen.
- a user is looking for a dull orange shade which he can use to dye cotton tricot. He decides upon the shade denoted by Px in Fig.4, which he locates quickly on the screen.
- the dye recipe for the colour is recalculated by way ofthe corresponding reflectance curve. The recipe is as follows:
- the digital recipe data are communicated to the jet- or spray-dyeing apparatus to control e.g. an automatic dosing system indicated above, either directly as communicated or after being submitted to an arithmetic operation to yield a format which may be processed by the jet- or spray-dyeing apparatus, thereby dyeing the mercerised cotton satin fabric pretreated as given above.
- control e.g. an automatic dosing system indicated above, either directly as communicated or after being submitted to an arithmetic operation to yield a format which may be processed by the jet- or spray-dyeing apparatus, thereby dyeing the mercerised cotton satin fabric pretreated as given above.
- the fabric is dried on line with an integrated hot air dryer at 100°C. A dyeing having very good fastness to washing is obtained.
- the colour ofthe dyed fabric is identical in terms of shade, colour saturation and depth of shade to the shade Px from the catalogue that was determined arithmetically.
- Fig. 1 is a diagram showing a depth of shade plane in the FTa*b* colour space, being segmented into 3 triangular areas, points P1 to P5 being corner points ofthe triangular areas.
- Fig. 2 is a diagram showing a depth of shade plane in the FTa*b* colour space, being segmented into 12 triangular areas, points P1 to P9 being the corner points ofthe triangular areas.
- Fig. 3 shows the gridded segment having the corner points P2, P3 and P4 of Fig. 1.
- Fig.4 shows the gridded segment having the corner points P10, P5 and P8, wherein P5 and

Abstract
Cette invention se rapporte à un procédé qui sert à teindre ou à imprimer un matériau de fibres textiles et qui consiste à cet effet à former un dispositif de traitement de données numériques organisant des données de courbe de réflectance qui sont associées aux recettes de colorants correspondantes. On génère ces données de courbe de réflectance: (a) en traçant un profil de nécessité pour la teinture souhaitée; (b) en sélectionnant un groupe de colorants qui satisfont au profil de nécessité ayant été tracé; (c) en déterminant dans l'espace des couleurs la position des couleurs des colorants pour la teinture souhaitée; (d) en segmentant l'espace des couleurs des colorants dans une profondeur de plan de teinte en zones triangulaires; et (e) en divisant ces zones triangulaires dans une profondeur de teinte de façon arithmétique en une grille.
