The protection provided by clothing against ultraviolet (UV) radiation has been the subject of
considerable recent research. However, a lack of investigations concerned with the
influence of yarn properties on UV protection capabilities of fabrics seems to be present.
This study investigated the influence of yarn twist and surface geometry on these properties
of fabrics. The gray-state plain cotton knitted fabrics were produced from yarn differing in
twist level under controlled conditions, so as to obtain as similar as possible construction
of the fabrics. These plain knitted (single jersey) fabrics were spectrophotometrically
assessed and UV protection factor was calculated. The results obtained indicated that yarn
twist to a great extent influenced the UV protection properties of the knitted fabrics through
the influence on yarn compactness and surface properties, which in turn influenced the
open porosity of the fabric. The results were also interpreted as the consequences of
minimal differences between knitted fabrics' construction (different stitch density), which
could not be avoided because of the yarn twist differences.
