Abstract

The Institute of Natural Fibres and Medicinal Plants has been carrying out a complex research related to application of natural dyes on fabrics. Colors of nature, obtained from various plants, have contributed to creating a collection of clothes produced from linen fabrics. The UV radiation can cause earlier skin ageing, burns and even skin cancer. The increasing hazard posed by UV radiation due to thinning of the ozone layer forces the textile producers to pay attention to providing textile products with barrier properties that would guarantee the protection against harmful UV radiation. The results of the studies proved that many fabrics dyed with dyeing plants using the original method developed at INF&MP are characterized with good or very good protection factors. Fengurek Trigonella foenum-graecum, coreopsis Coreopsis tinctoria L., knotgrass Polygonum aviculare L., India madder Rubia cordifolia L. the are represent group of plants with excellent UV properties. Key words: natural dyestuffs, dyeing plants, UV radiation, ecology, colors
