Textile UV Protection
Textiles are intrinsically suited for use as UV protection, as they are able to offer particularly good protection against intense radiation from the sun if suitable materials and constructions are used. UV protection factors (UPF) far above those of the strongest sunscreens (sunblocks) can be achieved.
It is not possible to determine how much UV radiation a textile allows to penetrate the skin simply from looking at and feeling the textile and thereby give a UV protection factor comparable to those used for cosmetic sun screens.
To determine this so-called Ultraviolet Protection Factor (UPF), standardised measuring methods and a specialist test, as offered members of the International Test Association for Applied UV Protection, are required.
