“…The results reveal a similar trend of UPF rating for control dyed samples of 1%, 2%, 3%, 4%, and 5% as 29, 31, 32, 33.3, and 33.7, respectively. Previous studies revealed that fluorescent dyes have inherent UV protection characteristics [ 34 ]. Once the fabric was treated with the nonionic polysorbate-incorporated dye, the UPF readings changed to 43.92, 43.14, 44.48, 46.52, and 53.71, respectively.…”

“…Once the test is completed, an assessment is conducted considering the contrast between the unexposed and exposed portion of the samples using the greyscale (James heal, UK). The higher the rating the better the light fastness property of the textile [ 34 , 36 ]. Test results in Table 3 depict that the treated samples have higher ratings compared to the control samples.…”

“…Test results in Table 3 depict that the treated samples have higher ratings compared to the control samples. That is a sign of better light fastness [ 34 ]. Test results depict that the incorporation of polysorbate enhances the fabric’s resistance to photo fading compared to those without polysorbate.…”

Technological advancement leads researchers to develop multifunctional materials. Considering such trends, this study aimed to conjugate dual functionality in a single material to satisfy aesthetic and functional necessities. We investigated the potentiality of polysorbate 20 to perform as an effective ultraviolet absorber to develop UV-protective fabric. Coumarin derivative (Benzoxazolyl type) disperse dyes are well-known as fluorescent colors. On the other hand, luminescence materials are conspicuous and viable for fashion trends. Deliberate utilization of this inherent property of the dye and incorporation of polysorbate fulfilled the need for dual functionality. In addition, the knitted fabric structure enhanced wearing comfort as well. The effect of polysorbate consolidated the PET fabric as an excellent UV absorber, exhibiting an ultraviolet protection factor (UPF) of 53.71 and a blocking percentage of more than 95% for both UVA and UVB. Surface morphology was studied by scanning electron microscope (SEM). Fourier transform infrared spectroscopy (FTIR) with attenuated mode was used to investigate chemical modification. Moreover, X-ray diffraction (XRD) investigated the crystallography of the surface. Reflectance spectrophotometric analysis unveiled the color strength (K/S) of the dyed polyester fabrics. Finally, light fastness assessment revealed that the developed samples could resist a certain amount of photo fading under a controlled testing environment with the increment of ratings towards betterment.
