UV protection afforded by textile fabrics made of natural and regenerated cellulose fibres

摘要: Abstract In the last decades media have highlighted ozone depletion as major environmental problem resulting in an increase ultraviolet radiation (UVR) reaching earth's surface. Besides beneficial effects of human exposure to UVR, this is capable causing damage population. The healthy lifestyle becoming widely accepted by public, and UV protection provided clothing becomes significant subject interest producers consumers textile fabrics. Natural cellulose fibres are commonly used summer due their excellent comfort properties. However, these very poor ability. project, property fabrics made natural regenerated been compared analysed order highlight potential hemp fibre for development more sustainable functionalized (UV protective) products. A group homogeneous blended were manufactured a knitwear factory, evaluated terms structure, spectrophotometrically assessed indicate knitted merited sun ratings “good” pure hemp, through “very good” viscose containing ”excellent” category cotton based Relatively high values Ultraviolet Protection Factor (UPF) materials resulted from interaction type, yarn geometry, fabric properties common processing techniques. increased UVR transparency fabric, which elasticity limitations, overcame blending with other softer elastic (cotton, viscose). engineering approach proposed study was confirmed effective way create (more resource, pollution prevention, energy cost savings) products level at knitting production stage avoiding use any additional mechanical chemical treatments. These results revealed that future application added-value promising. co-ordinated effort different subjects agro- textile-industry chain need continue so overcome limitations associated
