The results show that there are five healthy functions incorporated effectively in bamboo-charcoal modified polyesters, such as good far-infrared radiation, good UV protection, certain negative ion emission, certain antibacteria and good absorption functions. The metal elements and carburets are mainly responsible for far-infrared, negative ion emission functions. UV prevent/on function results mainly from the carbon elements. The absorbability and bacteriostasis functions lie in the porous structures.展开更多
