【Abstract】 In this paper, a self-designed device of cotton fibre pretreatment is adopted. Using this device,WAN solvent-exchanging drying method of cotton fibre has been developed and improved. Afterbeing subjected to a process of solvent-exchanging and drying, the specific area and pore-size distri-butions on cotton fibre are determined with a home-made Model ST-03 Specific Area & Pore-SizeDistribution Meter. It has been proved that the specific area of cotton fibre obtained by this methodcan be in a good agreement with the actual value of the specific area of cotton fibre, which offersa possibility for further studying of cotton fibre surface properties.更多还原
