controlpanelHeat flow plots of 0.5 g long-staple seedless cotton at0.2◦C min−1heating rate from 30◦C to 300◦C in the tests with andwithout a high pressure atmosphere control panel are shown inFig. 1. For sample tested without the panel, two exothermic pro-cesses are observed, i.e. a minor exothermic peak followed by amain exothermic process. This result agrees with that reported byWang et al. (2008)
