“…Figure 4 shows the XRD plots of the pure cotton and GO-PEG-g-Cotton (before and after 20 laundry cycles). All the samples exhibited identical diffraction peaks at 2θ = 14.9°, 16.52°, 22.91°, and 34.58°, which are in agreement with Miller indices for cellulose Iβ and represent (110), (110), (200), and (004) crystallographic planes of cotton 35 , 45 , 46 . Since the PEG was chemically grafted on the cotton backbone, the peaks in GO-PEG-g-Cotton at 2θ = 19.43°, 23.31°, 26.40°, 36.288°, and 39.78° were attributed to PEG, which is consistence with the XRD peaks as presented in Fig.…”

A thermoregulating smart textile based on phase change material (PCM) polyethylene glycol (PEG) was prepared by chemically grafting carboxyl-terminated PEG onto cotton. Further deposits of graphene oxide (GO) nanosheets were made on the PEG grafted cotton (PEG-g-Cotton) to improve the thermal conductivity of the fabric and to block harmful UV radiation. The GO-PEG-g-Cotton was characterized by Attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR), Raman spectroscopy, X-ray diffraction (XRD), x-ray photoelectron spectroscopy (XPS), and field emission-scanning electron microscopy (FE-SEM). With an enthalpy of 37 and 36 J/g, respectively, the DSC data revealed that the functionalized cotton's melting and crystallization maxima occurred at 58 °C and 40 °C, respectively. The thermogravimetric analysis (TGA) presented that GO-PEG-g-Cotton was thermally more stable in comparison to pure cotton. The thermal conductivity of PEG-g-Cotton increased to 0.52 W/m K after GO deposition, while pure cotton conductivity was measured as 0.045 W/m K. The improvement in the UV protection factor (UPF) of GO-PEG-g-Cotton was observed indicating excellent UV blocking. This temperature-regulating smart cotton offers a high thermal energy storage capability, better thermal conductivity, thermal stability, and excellent UV protection.

“…In both samples, carbon, oxygen, nitrogen, and silicon were observed as the main constituent elements 41,45,46 . During the processing of textiles (spinning/ weaving/chemical processing), different silicon-based softeners are applied to yarn or fabric to improve its smoothness and prevent it from being damaged by different machine parts.…”

“…So, ber reactive dyes particularly with better and enhanced printing properties are still in demand. Reactive dyes having high solubility in the printing paste with su cient a nity and substantivity are requisites for the printing of cellulosic fabric at the same time [18][19][20] . Moreover, dyes should have suitable tinctorial yield, great reactivity, and less dye e uent with the highest degree of xation.…”

Urea free screen printing of cotton fabric using newly synthesized azo reactive dyes was carried out in the present study. Functional group chemistry and its effect on the printing properties of cotton fabric by varying the nature, number and position of reactive groups of synthesized azo reactive dyes (D1-D6) was studied. Different printing parameters (Temperature, alkali and urea) and their effect was explored on the physicochemical printing properties e.g., fixation, color yield, and penetration of the dyed cotton fabric. Data revealed that dyes with more reactive groups and having linear and planar structures (D-6) showed enhanced printing properties. Spectraflash spectrophotometer was used to evaluate the colorimetric properties of screen-printed cotton fabric and results showed superb color buildup. Printed cotton samples displayed excellent to very good ultraviolet protection factor (UPF). Presence of sulphonate groups and excellent fastness properties may entitle these reactive dyes as commercially viable for urea free printing of cotton fabric.

“…Kumar et al utilized screen printing for coating CaF 2 nanoparticles (NPs) to prepare antibacterial cotton fabric. 25 In this study, the pristine cotton cloth was imparted with thermoregulating, antibacterial, and UV protection properties by successfully coating PEG and BT-NPs onto a textile surface by utilizing screen printing. The resulting fabric samples were characterized by attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), X-ray diffraction (XRD), and field emission scanning electron microscopy (FE-SEM) for surface modification, differential scanning calorimetry (DSC) for analyzing heating and cooling enthalpies, and UV spectrophotometry for recording UV absorption spectra.…”

The phase change material (PCM) polyethylene glycol (PEG) and ferroelectric material barium titanate (BaTiO3) nanoparticles were added to a stock paste to form a pigment–binder formulation. The resultant mixture was then directly screen printed onto cotton fabric. The coated cotton was characterized by attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), and UV spectrophotometry. The thermoregulating capabilities of both pristine and coated cotton samples were investigated with the use of a differential scanning calorimeter (DSC). For the 100th heating and cooling cycles, the melting and crystallizing enthalpies of modified cotton were found to be 23 J/g and 21 J/g, respectively. Against Staphylococcus aureus and Escherichia coli, the modified fabric showed a bacterial reduction of more than 99%. After 20 washing cycles, the bacteria growth was effectively suppressed by more than 91%. The coated fabric showed a UV absorption peak around 300–330 nm, capable of blocking harmful UV rays. The modification of cotton did not change its intrinsic properties such as breathability and its mechanical properties. The finished product has tremendous opportunities and offers an excellent replacement for conventional garments for applications in medical textiles and daily wear garments.
