Clothing is worn in single- and multiple-layer arrangements and during use subjected to
conditions such as extension and wetting. This study investigated how selected variables
affected transmission of ultraviolet radiation (UVR) through fabrics and whether these
variables interacted to modify transmission. Using a spectrophotometer the effect of i) fabric
type (two knitted, two woven), color (black and white), wetness (dry, damp, wet), and
extension (relaxed, extended (10 × 10%, 10 × 20%)), and ii) fabric type and layering (1, 2, 3
layers) of white fabrics, on UVR (290—400 nm), UVA (315—400 nm), UVB (290—315 nm), and
ultraviolet protection factor (UPF) rating was investigated. Differences among variables were
identified using univariate and repeated measures ANOVA, and interactions among
variables identified and described. Selecting dark colors, limiting extension and layering
fabric were shown to be effective ways of increasing UV protection and UPF by decreasing
transmittance. However, the effect of color, extension and layering varied among fabric
types and modified UVA and UVB transmittance differently.
