摘要：
The protective properties of hats and clothing against solar ultraviolet radiation (UVR) have been the subject of considerable research for some time. However, not all garments provide sufficient protection from UVR. In this study, the ultraviolet protective properties of the fabrics dyed by Rheum and Lithospermum erythrorhizon were investigated. Experimental results revealed that the fabrics dyed with natural dyes had good ultraviolet protective properties. They could absorb about 80% of the ultraviolet rays. It was demonstrated that the UV-protective effect was strongly dependent on the absorption characteristics of natural dyes for UVR. Natural dyes such as Rheum and L. erythrorhizon had comparable UV-absorption performance to the common UV-absorber, benzophenone. (c) 2005 Elsevier Ltd. All rights reserved.
