Colour matching for smart and sustainable spinning of coloured textiles

Abstract

The colours and patterns of coloured textiles are usually obtained via dyeing or printing processes. However, these processes consume large amounts of electricity and cause water pollution, which affects the ecological environment. The hand feel of dyed fabrics is superior to that of printed fabrics. Three-channel rotor spinning is a highly flexible, adaptable and sustainable method for producing coloured textiles by blending precoloured fibres during the spinning process. Additionally, the process requires approximately half the water required for fabric dyeing or printing. Herein, the colour characteristics, as well as the advantages, of the coloured textiles produced by the new method are demonstrated. Three types of Stearns-Noechel models are modified to describe the relationship between the blending ratios and resulting textile colours. The colour-matching accuracy is high. As demonstrated by the results, the threechannel rotor spinning method can effectively promote coloured textile engineering.Processes which make coloration cheaper, simpler and highly flexible, in addition to being more sustainable, have never been more attractive. The approach outlined in this Feature article could be one of them. It involves AbstractThe colours and patterns of coloured textiles are usually obtained via dyeing or printing processes.

Intelligent manufacturing of color blended yarn: Color matching algorithm and manufacturing process through computer numerically controlled ring spinning system

“…24 The reflectance of rotor-spun yarn depends on the wrapper fibers and fiber configuration in the outer zone, which results in a different W value in S-N model in comparison with ring spun yarn. 9 In addition, the reflectance of rotor-spun yarn is greater than that of ring-spun yarn due to a smoother surface.…”

“…Many factors contribute to the coloration of yarn, such as the sample preparation, the fiber physical form (fineness, length, and surface state), the fiber configurations in the yarn, and the spinning process. 9,16 In particular, the yarn twist has a significant effect on the coloration of yarn. For example, Jin et al showed that the light reflectance of vortex spun yarn is lower than that of ring-spun yarn due to the disorderly arrangement of surface fibers.…”

“…By changing the drafting ratios of three rovings, one can manipulate the linear density and blending ratio of yarns. 9,10 After receiving the parameter information, the programmable logic controller (PLC) sends commands to regulate the speeds of the front, middle, and back rollers. The servo motors run according to a set of user-specified rules, and the photoelectric encoder sends the real-time running parameters to the PLC.…”

“…In textile production, the actual colors of fabrics do not precisely match with the colors of idealized samples due to the fiber physical form (fineness, length, and surface state) and manufacturing process. 9 The analytical model is a useful approach to predict fabric color. Typically, the Kubelka-Munk theory (K-M) is a model widely used in paper-making and color-using industries.…”

Preparation of Tungsten‐Based Polyvinyl Alcohol Waterborne Coating and Development of Photochromic Composite Fabric

“…The application of photochromic materials in textiles can be applied in pattern design, anti-counterfeiting clothing, [13] fashion clothing, UV protection, etc. [14] The common preparation processes of photochromic materials on textiles [15] include printing, [16] grafting, [17] spinning, [18] finishing, [19] dyeing, [20] and chemical crosslinking. [21] The common preparation methods of photochromic textile [22] materials are grafting, [23] electrospinning, and coating.…”
