“…The region of 1670-1820 cm −1 generally represents the presence of C=O carbonyl functional group [25] on the carbon fibre surface after laser treatment and peak intensity is more obvious in 1670-1700 cm −1 (Circle (b)). The increase in peak intensity in 1670-1700 cm −1 indicates that oxygencontaining groups are introduced over the carbon fibre surface after laser treatment which may be due to the thermal oxidation effect [16][17][18]. On the other hand, peak intensity in the region 1050-1250 cm −1 (Circle (e)) is increased which represents the C-O-C [26].…”

“…After laser-treatment, the contact angle of the laser-treated carbon fibre fabric decreases to different extents, with the variation of pixel time and resolution. Generally, the increase in pixel time and resolution increases laser irradiation energy to interact with the substrate surface [16][17][18]. However, the level of laser irradiation energy depends on the combination of the laser process parameters of pixel time and resolution [16][17][18].…”

“…Generally, the increase in pixel time and resolution increases laser irradiation energy to interact with the substrate surface [16][17][18]. However, the level of laser irradiation energy depends on the combination of the laser process parameters of pixel time and resolution [16][17][18]. The decrease in contact angle of laser-treated carbon fibre fabric indicates that wettability of fabric is changed and the laser-treated carbon fibre fabric can absorb water easier than untreated carbon fibre fabric.…”

“…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]. Therefore, the aim of this study was to evaluate the impact of CO 2 laser treatment on carbon fibre fabric.…”

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 effect of laser treatment, using commercially production scale laser machine, on colour properties, involving its effect of dyeing, on 100% cotton woven fabrics has been studied in recent years [7][8][9][10] but its effect on cotton-blended fabrics, such as cotton/polyester fabrics, have been seldom reported. In our previous work [8,11], we compared some physical and chemical properties of laser treated pure cotton and cotton/polyester blended fabrics.…”

Abstract:In this study, laser was applied to two types of cotton-based woven fabrics in order to study the effect of CO 2 laser technology on colour and fabric strength properties. The woven fabrics had different fibre compositions, i.e., one was 100% cotton while the other had 60% cotton blended with 40% polyester. They were treated with different combinations of laser processing parameters, i.e., resolution (52, 60, and 68 dpi) and pixel time (110, 120, 130, and 140 µs). There were two approaches adopted: (1) laser treated and then dyed (LD); and (2) first dyed and then laser treated (DL), in order to study the effects of the two different sequences on the resultant colour. Colour properties include reflectance value, colour yield, CIE L*a*b* values and levelness measured by spectrophotometer; pH value and tensile strength were also measured. It was discovered that laser treatment had no influence on chromaticity of cotton fabrics. Moreover, fabrics treated with laser had a lighter shade than the control samples. This confirmed that both approaches, i.e., laser treatment conducted before and after dyeing, can provide a colour fading effect. The tensile strength of fabrics was affected differently in relation to the dyeing and laser process. According to results obtained from the pH measurement, it is confirmed that laser treatment can provide a colour fading effect without affecting the pH value, and the fabrics can be used instantly right after the laser treatment.
