UPF swimming knitting fabric

Fabric code: SP5LJ01

UPF is the abbreviation of Ultraviolet Protection Factor and it indicates how much UV radiation (both UVB and UVA) a fabric allows to reach your skin.For example, a UPF 50 fabric blocks 98 percent of the sun's rays and allows two percent (1/50th) to penetrate, thus reducing your exposure risk significantly. Because of the radiation block, it’s a perfect fabric for swimming suits.
