Study On Fabric Coloring Law Based On Primary-color Fibers Blending

The sense of color for textile is an important aspect of its visual style, the colorful textiles andcombination ways provide consumers with a variety of visual and emotional experience. Theexisting ways of textile color-displaying include such categories as sliver dyed or piece dyedfabric, yarn-dyed fabric, color patterned fabric, jacquard fabric, printed fabric, ect. With theprocess of fiber coloring and blending, sliver coloring or printing, yarn dyeing, piece-dyeing,printing and bronzing, rich colors and gorgeous patterns can be formed on the surface of fabric, atthe same time, the additional value of textiles will be greatly improved. Therefore, the study oncolor-displaying method for textile is of great significance.As a main category of textiles, plain colored fabric is mostly processed with sliver dyeing orpiece dyeing. The piece dyeing method is difficult to deal with blended fabric containing disparatefibers with conflicting dyeing conditions, while the sliver dyeing method needs to dye variousfibers to match target color, with complicated progressive proofs, making it hard to improveproduct quality and production efficiency, as well as causing water pollution problems in theprocess of dyeing. This paper introduces the color displaying method based on primary-colorfibers blending is put forward, which is based on primary-color mixing theory in the printingindustry, optimizing primary-color dyestuff and dyeing to obtain Yellow, Magenta, Cyan andBlack colored fibers, then choosing two or more kinds from the Yellow, Magenta, Cyan, Black andunbleached fibers, and blending them evenly with different quantity proportion, afterwards withspinning and weaving processes, plain colored fabric with macroscopically uniform view and richcolors will be formed.The paper regards wool fiber as research object, and aims at reactive dyes Lanasol, weakacid dye Lanaset, and strong acid dye Neolan, and sets five concentration levels for eachdyestuff mentioned above to obtain wool fibers of different colors. At the same time, referring to the color characteristic value and the spectral reflectance of a set of four primary-color ink, bymeans of chromatic difference analysis and the mathematical statistics analysis of spectrumreflectance value, the dyestuff category and concentration level is determined respectively forYellow, Magenta, Cyan and Black colored fibers. In addition, color space based on primary colorfibers blending is approximately characterized, showing that a rich kind of colors can be displayedwith primary color fibers blending.Secondly, on the base of determining Yellow, Magenta, Cyan and Black primary color fibers,this paper analyzes and compares the feature and differences of two color displaying methodsbetween primary color fibers blending and primary color dyestuff mixing, indicating that colordisplaying method based on primary color fibers blending is the innovation and supplement of thatbased on primary color dyestuff mixing, providing a practical solution to dyeing blended fabriccontaining disparate fibers with conflicting dyeing conditions.Last but not least, this paper refers to Yellow, Magenta, Cyan, Black and uncolored woolfibers as basic materials, on the one hand, choosing a series of mass blending proportions forprimary color fibers mentioned above, then through blending evenly the primary color fibersfollowed by conventional spinning and weaving processes, plain colored fabric samples withdifferent color types are made, showing the appearance similar to that of sliver dyed or piece dyedfabric, while displaying multicolored fibers in micrometer scale within some short viewingdistance, as well as a delicate sense of color. In addition, with the empirical Stearns-Noecheloptical model, the relation between spectral reflectance and the formula of blending samples to becalled mass mixing proportion is predicted, showing the prediction result is consistent withmeasurement result, indicating the Stearns-Noechel optical model is applicative to blending colorlaw for wool fibers; On the other hand, choosing a series of mass blending proportions for primarycolor fibers according to characters of color appearance, then through controlling the evennessdegree of blending fibers to form uneven color effect complying with the design requirements inthe yarn, followed by weaving process to make color patterned fabric samples, showing exquisitecolor texture and layering variation, as well as a more casual, irregular and novel appearance style.
