This study investigated the use of two instruments to measure the ultraviolet protective factor (UPF) of T-shirt knit fabrics. After various laundering treatments, specimens were cut and UPF was measured from the wale, course, and bias directions with the ISO MET® UV-Meter and the Cary UV-Visible Spectrophotometer. Similar results were found between the two instruments and among repeated measures. Before UPF measurement, the shirt fabrics were repeatedly laundered using various household… 
The Impact of Fluorescent Compounds on the Change in Shade of Pastel Colored PES/Cotton Fabrics
Abstract Functionalization of textiles in the finishing and care processes is an outstanding topic today. Ultraviolet (UV) protective properties of textiles can be improved by the implementation of
Ultraviolet protection of weft-knitted fabrics
Increased incidence of skin cancers worldwide has expedited the development and research of ultraviolet (UV)-protective clothing. Clothing acting as a ‘second skin’ for human beings provides a more
Impact of Artificial UV-Light on Optical and Protective Effects of Cotton After Washing with Detergent Containing Fluorescent Compounds
Abstract Bleached cotton and polyester/cotton blend fabrics were laundered at 60°C and 90°C with standard ECE detergent with addition of selected fluorescent compounds through 10 cycles. As
The Influence of Iron Ions on Optical Brighteners and Their Application to Cotton Fabrics
Both optical brighteners were influenced by iron ions in the sense of fluorescence quenching and in single- and two-bath treatments of cotton fabrics after one cycle on whiteness degree and UPF was negligible.
Garments as solar ultraviolet radiation screening materials.
Update on photoprotection
Habitual use of sunscreen is recommended with UV exposure, and concerns for vitamin D deficiency with sunscreen use should not supersede proper photoprotective behavior.


Reduction of ultraviolet transmission through cotton T-shirt fabrics with low ultraviolet protection by various laundering methods and dyeing: clinical implications.
The two cotton fabrics used in this study offered limited protection against UV radiation as determined by spectrophotometric analysis, and laundering with detergent and water improves UPF slightly by causing fabric shrinkage.
Improving Sun Protection Factors of Fabrics by Applying UV-Absorbers
Designing and modifying fabrics in such a way that they offer high protection against UV-light ("UV-cutting") is a relatively new application. Thin, untreated fabrics made, for example, from cotton,
Effect of OBAs and Repeated Launderings on UVR Transmission through Fabrics
Eight types of summer-weight fabrics were subjected to 20 home launderings in a bid to develop better fabrics for sun protective clothing and found to have the opposite effect on UVR transmission through fabrics.
Protection of Humans from Ultraviolet Radiation through the Use of Textiles: A Review
The need for appropriate protection from the sun, especially for children, and the benefits of clothing as protection are identified, and Fabric variables, identified in the literature, that have been found to affect UVR transmission values are discussed.
UV protection by clothing: an intercomparison of measurements and methods.
Results from an intercomparison involving five independent testing laboratories show agreement is good, in particular for samples with protection factors below 50, and technical difficulties and sources of errors associated with the measurements are discussed.
Ultraviolet radiation protection factors for clothing.
A scheme to designate the amount of ultraviolet radiation protection of materials using ultraviolet protection factors is outlined and used to compare the results obtained by different test methods.
Textiles and sun protection.
The spectral transmission of ultraviolet radiation was measured through natural textiles and human-made textiles, and the protection afforded by a given fabric depended more on the nature of the weave than on the particular type of textile.
Sun protection of the skin with a novel UV absorber for rinse cycle application
Thanks to its compatibility with cationic materials TINOSORB FR adds a supplementary effect to rinse cycle fabric conditioners. The significant enhancement of the UPF as well as the whitening effects
The effect of laundering on the sun protection afforded by a summer weight garment
Aim To determine what effect a period of prolonged washing and drying of a garment would have on the photoprotection afforded by the fabric of that garment.
Sun protection by a summer‐weight garment: the effect of washing and wearing
To assess the effect of use (washing and wearing) on the photoprotection provided by a cotton fabric, a large number of fabrics were selected to be tested.
