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.

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.

Weave Fabric ◽

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.

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.
