Ultraviolet Protection

In thisstudy, the effect of fabric density and different colors (black and red) on ultraviolet protection factor of woven fabric investigated. The fabric of different composition (100% cotton, 60/40 CVC), two color (black, red) and various density (Ends per inch, Picks per inch) collected. Then UPF rating was measured by spectrophotometer in vitro method. Experimental result showed that higher the fabric density and weight; higher the protection from ultraviolet rays. Besides, it also revealed that black fabric has more UV protection ability than the red one. Another finding of this study is that polyester content increases the UPF value.

Single Jersey

In this study, 6 commercially available single jersey knit outerwears were collected from the market which claimed to have ultraviolet protection factor of 25. In vitro method with the use of spectrophotometer was used for evaluating their ultraviolet protection properties under different stretch conditions. Experimental results revealed that the stretch would greatly reduce the UV protection properties of knit outwears.

Ultraviolet Protection

Purpose The purpose of this paper is to investigate the effect of materials, three dimensional (3D) structure and number of fabric layers on ultraviolet protection factor (UPF), air permeability and thickness of fabrics. Design/methodology/approach Total 24 fabrics samples were developed using two 3D structures and two weft materials. In warp direction cotton (CT) yarn and in weft direction polypropylene (PP) and polyester (PET) were used. Air permeability, thickness and UPF testings were performed and relationship among fabric layers, air permeability, thickness and UPF was developed. Findings UPF and thickness of fabrics increases with number of fabric layers, whereas air permeability decreases with the increase in number of fabric layers. Furthermore, change of multilayer structure from angle interlock to orthogonal interlock having same base weave does not give significant effect on UPF. However, change of material from polyester (PET) to polypropylene (PP) has a dominant effect on UPF. Minimum of three layers of cotton/polyester fabric, without any aid of ultraviolet radiation (UV) resistant coating, are required to achieve good. Cotton/polyester fabrics are more appropriate for outdoor application due to their long-term resistance with sunlight exposure. Originality/value Long-term exposure to UV is detrimental. So, there is need of proper selection of material and fabric to achieve ultraviolet protection. 3D fabrics have yarns in X, Y as well as in Z directions which provide better ultraviolet protection as compared to two dimensional (2D) fabrics. In literature, mostly work was done on ultraviolet protection of 2D fabrics and surface coating of fabrics. There is limited work found on UPF of 3D woven fabrics.

Single Jersey

In this study, 6 commercially available single jersey knit outerwears with different colour were collected from the market which claimed to have ultraviolet protection factor of 25. In vitro method with the use of spectrophotometer was used for evaluating their ultraviolet protection properties. Experimental results revealed that the L* values has a higher correlation with UPF but a* and b* values do not have a significant correlation with UPF of fabrics. Moreover, all samples had a UPF value higher than 25.

Single Jersey

We collected 6 commercially available single jersey knit outerwears from the market which claimed to have ultraviolet protection factor of 25. In vitro method with the use of spectrophotometer was used for investigating their ultraviolet protection properties under different moisture conditions. Experimental results revealed that the moisture would greatly reduce the UV protecion properties of knit outwears. The higher the moisture content, the lower will be the UV proection properties of the outwears.

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+.
