“…This change in wettability may be due to the introduction of hydrophilic functional groups on the carbon fibre surface. Those hydrophilic functional groups may be the oxygen-containing functional groups [13]. Since laser treatment was conducted in atmospheric conditions, the high laser irradiation energy together with the ambient oxygen introduce oxygen-containing functional groups to the carbon fibre fabric surface as shown in Figure 8.…”

“…Due to the increasing concerns on environmental protection issue, CO 2 laser treatment is a method for surface treatment which is based purely on physical interaction between the laser and the material surface [8][9][10][11][12]. Previous studies reveal that CO 2 laser treatment is a good candidate for changing aesthetic properties of materials in fabric form [13][14][15]. With careful control of CO 2 laser treatment process parameters, the aesthetic effects (surface textual effects) can be controlled with minimum damage of the material itself [16][17][18][19][20].…”

Abstract:The colour of carbon fibre fabric is black which limits its aesthetic properties. CO 2 laser has been used for cutting carbon fibres. The impact of CO 2 laser treatment to modify the surface of carbon fibre fabric is investigated in this work. Different combinations of laser process parameters, i.e., pixel time (110, 120, 130, 140, 150, 160, 170, 180, 190 and 200 µs, with 10 µs intervals) and resolution (70, 80, 90 and 100 dpi (dots per inch), with 10 dpi intervals), were used for treating carbon fibre fabric surface. Since the laser process is a surface treatment, contact angle measurement was used for evaluating the wetting property imparted after laser processing. The resistivity of the laser-treated carbon fibre fabric was measured to evaluate any effect on the original electrical property of the carbon fibre fabric. Moreover, surface morphology and functionality of laser-treated carbon fibre fabric were assessed by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy-attenuated total internal reflectance (FTIR-ATR), respectively. SEM assessment was to examine the physical change in the carbon fibre surface after laser processing. On the other hand, the FTIR-ATR measurement can help to evaluate the chemical change in the carbon fibre surface after laser processing.

“…However, the tensile strength (warp direction) for heavyweight fabrics were higher than lightweight fabrics. Generally, the loss of strength is more in warp direction than weft, which is confirmed when laser pulse increases [21,23]. The tensile strength depends on fibers, yarns, and fabric [40].…”

“…Owing to these developments, researchers studied various laser variations or equipment to produce surface effects as the process was environmentally friendly compared to conventional methods [17]. Some studies [17,22,23] reported the effect of laser treatment on denim fabrics using pixel time and dots per inch (dpi) as one of the main parameters determining the colour contrast difference between pristine denim and treated denim and affecting other physical properties of the fabric.…”

Laser treatment of denim fabrics was demonstrated as one of the methods of producing distressed effects and is continuing to attract textile and fashion designers to develop bespoke designs that appeal to all age groups. Two dark shaded indigo-dyed 100% cotton twill fabric with varying weights representing various garment applications were laser treated using a commercially available pulsed CO2 laser of wavelength 10.62�m. Pulses per inch, which is the degree of closeness of laser irradiation, was maintained at 300 and 400 PPI. Treated denim fabrics were evaluated for tensile strength, colour measurements, including colour hue (H), saturation (S), brightness (B), reflectance, K/S (colour yield), CIE L* a* b*, fabric thickness and colourfastness after wash. Results indicated that colour contrast of denim fabric enhanced with the increase in grayscale (tone density) for both the LW (lightweight) and HW (heavyweight) fabrics, mainly at lower laser speed (80%) and higher laser power (40%). At higher grayscale (30% GS), surface fibers charred due to laser and the oxidation of cellulose occurred, causing a distinct yellow tone compared to pristine denim. Fabric tensile strength was affected as grayscale and laser parameters increased, the variation from pristine denim for LW fabric was 40 - 45% at 30% GS, whilst for HW fabric, variation was 25-30%. Colourfastness tests revealed limited colour staining, and it removed charred fibers showing a distinct tone change. This research recommends a combination of fabric and laser parameters to produce patterns without affecting the overall quality of the fabric.

“…Several studies have already been conducted and reported the overall suitability and feasibility of the laser engraving on the textile materials [19,25,26,27,28]. The potential changes in the color and mechanical properties of the denim due to the laser engraving process have extensively been studied in previous studies [13,18,24,29]. Besides, Juciene et al studied the effect of the technological parameters of CO 2 laser on the color of indigo-dyed denim [30].…”

This research aims to develop a fuzzy logic-based model for predicting the warp way and weft way Tearing Strength (TS) of laser engraved denim garments concerning two of the most important laser parameters such as Dots Per Inch (DPI) and Pixel Time (PT). Laser engraving is a widely used approach in garment washing factories because of its lower health hazards, time efficiency, and accuracy than other processes. However, controlling the laser parameters is very important, as if the tearing strength of the treated garments falls lower than the tolerable limit, the garment might be rejected. In this study, the fuzzy logic-based method is used to develop a prediction model to determine the Tearing Strength of the laser engraved denim. The model exhibits the exact same trend for TS as the experimental findings, i.e., TS increases with the decrement of either DPI, PT, or both. Moreover, the Mean Relative Errors (%) for warp and weft way Tearing Strength was found to be 3.34 and 3.53, respectively, which are within the acceptable limits. The coefficient of determination (R 2 ) was found 0.98 (R ¼ 0.99) for both the warp and weft way Tearing Strength, and the result suggested that up to 98% of total changes in warp and weft way Tearing Strength can be explained by the model. From the results, it can be evident that the principle of the proposed model can satisfactorily be used in predicting the Tearing Strength of the laser engraved denim garments, which will be beneficial for the garment washing industry by eliminating a lot of existing trial and error approach to set process parameters and thus can play an important role in increasing the productivity by process optimization.
