Sunlight includes rays of invisible ultraviolet (UV) radiation; over exposure to UV rays can lead to sunburn, accelerated skin aging and skin cancer. Sunscreen and clothing offer your main forms of UV protection.
All fabrics disrupt UV radiation to some degree. Clothing that does the best job carries an Ultraviolet Protection Factor (UPF) rating from 15 (good) to 50+ (excellent).
Ultraviolet Protection Factor (UPF) is a rating system used for apparel. It indicates how effectively fabrics shield skin from ultraviolet (UV) rays.
UPF is similar to SPF (Sun Protection Factor), the rating system used for sunscreen products. UPF measures a fabric's effectiveness against both ultraviolet A (UVA) and B(UVB) light. A SPF number pertains only to a sunscreen's effectiveness against UVB rays, the sunburn-causing segment of the ultraviolet spectrum.
Effective UV-R Transmission (%)
25, 30, 35
Less than 2.5
40, 45, 50, 50+
Basically, an UPF rating of 50 indicates the fabric of a garment will allow only 1/50th (roughly 2%) of available UV radiation to pass through it. A garment rated UPF 25 permits roughly 4% (1/25th) UV transmission.
Which means the higher the number is, the better the protection the fabric offers.
We guarantee that every Drotex® Anti-UV rays fabric can reach UPF50+.
What Makes Drotex® Anti-UV rays Fabrics more Effective at Disrupting UV Rays than Others?
Space between Yarns Minimize the Amount of UV Light that Can Pass through

Chemical Effective, Environmentally Friendly
Currently, Anti-UV rays finishes for 100% cotton and cotton blend fabrics are available with varying levels of weights and durability. Contact us immediately for a comprehensive product catalog.
Wetness may cause a 30% to 50% reduction in a fabric's UPF rating.
If stretched 10% or way beyond its normal dimensions, spaces between yarns are widened and its effectiveness against UV light may be reduced up to 40%.
