In this study, the functionalization of nanofibers by incorporating different particles and additives into the polymeric matrix for developing ultraviolet protective materials was investigated. Titanium dioxide was selected because of its known characteristic of being a widely used material for obtaining ultraviolet protection. Besides, 1,3,7-Trimethyl xanthine, which was used previously in medical applications to decrease the harm of ultraviolet radiation on DNA, was used to see its potential in obtaining ultraviolet protective nanofibers. By using these two different additives in different concentrations, functionalized polyamide 6.6 nanofibers were produced, their ultraviolet protection property and ratings were recorded, and the results were evaluated comparatively. Addition of titanium dioxide in all concentrations significantly improved ultraviolet protection of polyamide 6.6 nanofibers for both UVA- and UVB-type radiations. Moreover, ultraviolet protection factor value of polyamide 6.6 nanofibers was considerably enhanced by incorporation of 1,3,7-Trimethyl xanthine in the concentrations of 15 and 20% w/w of the polymer; which of their protection ratings were defined as “excellent protection” for both.

Sulphur Dye

In this study, sulphur dye was used for dyeing 100% cotton knitted fabric and the effect of dye concentration and colour shade on ultraviolet protection factor (UPF) was discussed. The results indicated that the UVR absorbency of sulphur dye was not satisfactory. Generally speaking, the higher the dye concentration, the darker the shade of fabric. Nevertheless, it did not affect the UPF of fabric if the absorbency of the selected dye was ineffective.

In the present study, natural dye from cob of purple corn and various metallic salts have been used to identify the proper dyeing condition for attaining high quality natural dyeing along with imparting UV protection property to the dyed silk fabric. Silk fabrics dyed with cob of purple corn extract showed a violetish-pink shade, while those dyed with alum light violetish-pink shade colour. Silk substrates dyed with CuSO4 and FeSO4 gave a yellowish grey and violetish-gray colour, respectively. The fastness properties ranged from fair to good. The ultraviolet protection factor (UPF) values of silk fabric dyed with and without metal mordants ranged between very good and excellent.

Background: Topical sunscreens have been used for many years on exposed areas (i.e., hands, face) to protect the skin from the damaging effects of ultraviolet radiation. Most people do not use sunscreens on their bodies when they are wearing clothes. An average weight cotton T shirt gives only a sun protection factor (SPF) of 7. This is inadequate protection when out of doors. Therefore, clothing with adequate sunscreening properties should be worn. Objective: The purpose of this study is to identify the factors in clothing fabrics that contribute to or detract from blocking ultraviolet radiation and to recommend criteria for establishing a standard for sunprotective clothing. Method: The study involves a review of the dermatologic and textile literature to identify various factors in fabrics that contribute to blocking ultraviolet radiation through textiles. Conclusion: For fabrics, the term ultraviolet protection factor (UPF) is used as the measure of ultraviolet radiation penetration through the fabric. The UPF of a fabric depends upon fiber content and weave, fabric colour, finishing processes, and the presence of additives. The performance of a fabric depends upon stretching, shrinkage, hydration, laundering, and wear of the fabric over time. Based upon these criteria the minimum CDA standard UPF for clothing should be 40 to 50+.

Macerated Extract

The aim of the study was to investigate the anti-ultraviolet properties of β-cyclodextrin-grafted cotton fabrics dyed with broadleaf holly leaf extract. Flavonoids were extracted from broadleaf holly leaf by maceration and a stoichiometry of 1:1 inclusion complex with β-cyclodextrin was formed. Characterized by the fluorescence spectrum and ultraviolet spectrophotometry, the fluorescence intensities and ultraviolet absorption of the macerated extract were enhanced by increasing the amount of cyclodextrin. Cotton fabrics were grafted with β-cyclodextrin through a crosslinking reaction based on citric acid in the presence of sodium hypophosphite then dyed with the macerated extract of broadleaf holly leaf used as a natural ultraviolet absorbent. The anti-ultraviolet property of fabrics dyed by a macerated extract was characterized in terms of the ultraviolet protection factor. It was noted that the cotton fabrics grafted with β-cyclodextrin exhibit enhanced anti-ultraviolet and wrinkle recovery properties compared to the unmodified samples and show an excellent durability against 30 washing cycles, accompanied by a loss of tensile strength.

Background. The increasing emission of greenhouse gases has evoked the human being to save the ozone layer and minimize the risk of ultraviolet radiation (UVR). Various fabric structures have been explored to achieve desired ultraviolet protection factor (UPF) in various situations. Objective. In this study, the effect of various filament configurations like twisted, flat, intermingled, and textured in multifilament yarns on fabric in different combinations is assessed in order to engineer a fabric of better ultraviolet protection factor (UPF). Methods. In order to engineer a fabric having optimum UV protection with sufficient comfort level in multifilament woven fabrics, four different yarn configurations, intermingled, textured, twisted, and flat, were used to develop twelve different fabric samples. The most UV absorbing and most demanding fibre polyethylene terephthalate (PET) was considered in different filament configuration. Results. The combinations of intermingled warp with flat, intermingled, and textured weft provided excellent UVR protection comparatively at about 22.5 mg/cm2 fabric areal density. The presence of twisted yarn reduced the UV protection due to enhanced openness in fabric structure. Conclusion. The appropriate combination of warp and weft threads of different configuration should be selected judiciously in order to extract maximum UV protection and wear comfort attributes in multifilament woven PET fabrics.

Silk fabric was dyed with the colourant extracted from Laccifer Lacca Kerr. by using post-mordanting process and pad-dry technique. The effect of metal mordantats at different mordant concentration levels on their colour strength was also investigated. Silk fabrics dyed with Laccifer Lacca extract showed a light pink shade, while those dyed with alum and stannous chloride produces pinkish-red colour. Silk mordanted with CuSO4 gave a purple red colour, while those dyed with FeSO4 had a reddish-gray colour. The fastness properties ranged from fair to good, while washing fastness was poor level. The ultraviolet protection factor (UPF) values of silk fabric dyed with and without metal mordants ranged between good and excellent for dyed fabric.The results confirmed that natural dyes from Laccifer Lacca Kerr. extract have potential applications for silk fabric dyeing and producing ultraviolet (UV) protective silk fabric.
