Coloration Technology

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.

“…[3][4][5] With the mutual design of the overall pattern of the sweater and the fabric structure, as demonstrated by Figure 1, the integrated design and production of sweaters can be realized quickly with multisegment blending colored yarns such as rotor spinning gradient yarns and segment color yarns. 6 Rotor spinning is the second-largest spinning method that is second only to ring spinning in terms of market share. It has the advantages of high production efficiency and short process flow.…”

Multisection color-blended wool yarn produced by a new three-channel spinning method

Journal of Engineered Fibers and Fabrics

2019

By dynamically controlling the feeding amount and feeding ratio of the three feeding rollers with program logical control system under the requirements of yarn spinning parameters, it is possible to effectively configure the final yarn density and the blending ratio of three components to produce multisegment gradient yarns, segment-color yarn, and segment-color slub yarn named as multisegment blending yarns. The yarn-spinning new method was proposed. Different kinds of fancy yarns including gradient yarns, segment color yarns, and slub yarns were produced. The fiber blending effects were demonstrated by slices of yarn cross section, and the surface morphology of yarns were figured out by the photo of yarns. Integrally knitting seamless sweater and different type of pattern were designed and knitted by multisegment blending yarns. The free change of colors along the length direction on a single yarn provides an effective method for integrated rapid design and production of sweaters through mutual design of the overall pattern and the structure of the fabric.

“…Using this new method, the blend ratio of yarns can be controlled and achieved by asynchronous fed slivers. Thus, three primary colored fibers can be blended in suitable proportions to obtain as many targeted colors as possible in theory …”

“…Thus, three primary colored fibers can be blended in suitable proportions to obtain as many targeted colors as possible in theory. 3 The woven fabrics are various in color resulting from the difference in color, type, and blending ratio of the fiber. Any change of these aspects can cause color characteristic variation.…”

K‐M theory of fabric knitted by three‐channel rotor spun wool yarn

Color Research & Application

et al. 2018

Two‐component and three‐component color blended yarns were spun by red, yellow, and blue wool slivers using a three‐channel rotor spun machine, and the corresponding plain fabrics were knitted. The color‐matching models of K‐M theory were built with the relative method and the least squares method, respectively. Colors and blending ratios of the fabrics were predicted by the model. The results showed that the average color differences of the samples predicted by the two methods are both about 1.0 and the mean value of the proportional error is below 3%. The least squares method has a better color‐matching effect for the three‐component sample, and the relative value method has better color‐matching results for the two‐component sample. When the tolerance range is 2.0, the pass rates of the samples predicted by either the relative value method or the least squares method reach 100%.
