Effect of Bamboo Charcoal Content on the Heat Preservation Performance of Bamboo Charcoal/PET Blended Fibers

Abstract

The bamboo charcoal material was added in polyethylene terephthalate (hereafter referred to as PET) fiber spinning process in various proportions controlled at 0.5, 1.0, 1.5, 2.0 and 2.5% by weight to compose bamboo charcoal / PET blended fibers (hereafter referred to as BCE). The halogen light radiation method and the Thermo-vision analysis were applied to estimate the effect of bamboo charcoal content on the heat preservation performance of BCE. For a comparison, a carbon black / PET blended fiber (hereafter referred to as CBE) with a content of 1.5wt% commercial dope dyed carbon black material was utilized. The result indicated that BCE in all compositions showed a better heat preservation performance than CBE, and the 1.5wt% BCE achieved the highest value of relative heat preservation of 0.44℃. In addition, the removal test of ammonia gas revealed that BCE had a better removal effect than CBE, the reduction rates for ammonia gas in 100ppm primary concentration of 1.5wt% BCE and 1.5wt% CBE were 48% and 18%, respectively.
