“…The greatest changes in both L* and K/S values were examined between the not abraded fabric and the fabric after 2500 abrasion cycles. There was a small decrease in K/S values while observing a small increase in L* values after 2500 cycles which was compatible with the literature findings [5], [6], [10]. As previously stated, at earlier stages of abrasion tests, the fabric surface smoothness increases due to the removal of protruding fibers, and that brings higher light reflectance, causing L* values to increase and K/S values to decrease.…”

“…As previously stated, at earlier stages of abrasion tests, the fabric surface smoothness increases due to the removal of protruding fibers, and that brings higher light reflectance, causing L* values to increase and K/S values to decrease. At later stages of the test, the change is mostly due to internal abrasion of the fabric, and thus the change in both L* and K/S is limited, especially when reactive dyes which are strongly bonded to fibers are used for dyeing [2], [4], [10].…”

“…of the effects of an increased number of abrasion cycles on color values of knitted and woven fabrics made from different fiber materials such as cotton, wool, polyester, viscose and different yarn structures in different fabric construction parameters [4][5][6][7][8][9][10][11]. Alpay et al [5] showed that fabrics with ring spun and open-end spun weft yarns differ from each other in both reflectance and color difference values, which tend to increase as the abrasion cycles increase.…”

It is expected from a fabric applied with durable softener agent, not only a smooth, slippery and soft touch but also durable color even after several cycles of use and care. From this point of view, at this study weft knitted fabrics were manufactured using Siro, ring and open-end cotton yarns, bleached and dyed, followed by softening treatment with silicone, cationic and nonionic softeners at 1 and 3% softener concentration levels. Color strength and lightness values of the treated fabrics were evaluated by considering color changes after abrasion. Since the loss of fibers from a fabric surface during abrasion cycles causes prominent changes in the fabric's color, differentiation in the color that occur after a certain number of abrasion cycles (2500, 5000, 7500, 10000) were also measured for evaluation of the abrasion resistance of a fabric. Considering the yarn type and number of abrasion cycles, interaction effects of those with softener type and softener concentration on color strength and lightness were presented and discussed separately. From the results, it was observed that the color values of fabrics after abrasion cycles are closely related to yarn type, softener type, and concentration. The most significant changes in both L* and K/S values were obtained after fabric were abraded 2500 cycles. Softener type, as well as concentration, should be decided according to the target color shade before coloration.

“…More importantly, the nuance of the finished product is influenced by all chemical or mechanical including the knitting operations. Many problems influence the color quality such as the fiber characteristics, the parameters of manufacture and the textile structure itself [12]. The color change is also influenced by some other additional factors such as temperature, friction, water and atmosphere.…”

The present paper provides a systematic analysis on the character of color change from the transformation of dyed yarn into knitted fabric. First, the cotton yarn was dyed with Lavafix Brillant Red E4BA (a reactive dye) and Polyazo dye Solophenyl Red 3BL (a direct dye) with three nuances (1, 2 and 3%). Then two knitted structure were produced (rib 1x1 and single jersey). Further three couliering depths (11, 13 and 15) were varied during the manufacture of the knit fabric. The change of the color was analyzed via the measurement of the colorimetric coordinates (L*, a*, b*). The experimental results were modeled using a typical mathematical matrix of transformation. The color degradation of the rib 1x1 structure was very significant than that observed for the single jersey. As generally observed, the machine influences more strongly the degradation of the direct dye than the reactive one. This could be explained by the fixing process of the dye on the cotton yarn. As the change in color coordinates is very significant in the textile industry, this work could offer a new useful typical mathematical tool to study the influence of different parameters of knitting operation on color change.

“…A number of studies have been reported to evaluate the effects of increased number of abrasion cycles on color values of knitted and woven fabrics made from different fiber materials such as cotton, wool, polyester, viscose and different yarn structures in different fabric construction parameters. 9–15 From the color results, it was observed that color values of fabrics after abrasion cycles are closely related with fiber type, and yarn and fabric constructional parameters.…”

In this study, the color and color fastness properties of the dyed plain knitted fabrics made from 50/50 bamboo/cotton blended yarns with three different stitch lengths are investigated in comparison with those of the similar fabrics made from 50/50 conventional viscose/cotton and 50/50 modal/cotton blended yarns. Abrasion behaviors of the fabrics are assessed by measuring the weight loss and the color values after four different increasing abrasion cycles. The bamboo/cotton fabrics reveal the highest K/S and C* values, but the lowest L* values before abrasion. The lowest weight loss values are obtained for the bamboo/cotton fabrics. Regarding the color properties after abrasion, the bamboo/cotton fabrics show the highest K/S and C* values, but the lowest L* values as in the case of those obtained before abrasion. The highest color difference values (ΔE*) occurred between the beginning and the end of the abrasion test (20000 cycles) and are observed for the bamboo/cotton fabrics. The rubbing, wash and perspiration fastness results of the bamboo/cotton fabrics are found to be worse than those of the other fabrics having viscose/cotton and modal/cotton yarns. However, the highest light fastness results are obtained for the bamboo/cotton fabrics. From the color values after abrasion and the fastness results, it can be concluded that the bamboo/cotton fabrics having the better dyeing properties lose their color more easily than the other fabrics having the viscose/cotton and modal/cotton yarns. The results also indicate that stitch length affects the color values before abrasion and the weight loss and color values after abrasion.
