First Cotton T-shirt Earns Skin Cancer Foundation Endorsement
Since 1989 when the Solar Protective Factory (SPF) discovered that UV goes through t-shirts at an alarming rate they have been developing fabrics that are sun protective. In fact, SPF was the first and only company to have fabrics tested and certified by NASA. Additionally SPF, in co-operation with the American Society of Testing and Materials (ASTM), was instrumental in creating the most stringent fabric and apparel testing standards in the world. These standards assure the wearer UV protection even after the equivalent of two years wear and tear.
Fun in the sun. But which child has more protection from the sun’s harmful ultraviolet rays? Some t-shirts block less than 70% of UV while others can block more than 98% of UV. How can you tell? The Skin Cancer Foundation has only awarded its seal of recommendation to one all cotton t-shirt, the SPF t-shirt from spfstore.com.
Since 1990 when SPF introduced Solarweave many companies have tried to duplicate SPF fabrics with off-the-shelf nylon products claiming to be “medical devices” and polyester fabrics tested to Australian standards that are far less stringent than U.S. standards. These fabrics are just “renamed” generic fabrics.
SPF developed the Solarprotiferous process for maximizing fabrics’ UV protective properties. Innovations in fabric construction including thread type and loft, warp and fil weaving and knitting techniques; along with pharmacologically inert dyes and chemical treatments, recycled elements such as charcoal and coconut, titanium and other exotic compounds are all part of the Solarprotiferous process. This process fostered the creation of greatly enhanced reflectivity and absorption of ultraviolet rays. Additionally, transference of UV into infrared on fabric surfaces enhanced faster temperature stability on the outside of the fabric while creating a cooler shade under the fabric; greater protection and greater comfort were thus
