The Study of Moisture Absorption and Release Properties of Tencel Fiber

Tencel fiber is an environmental friendly regenerated cellulose fiber generated using solvent spinning method, which has been widely used in recent years for its good wearability. The experiment of moisture absorption and release properties was carried out in standard atmospheric conditions for different kinds of tencel fiber in this research, and then moisture absorption, moisture release, moisture absorption rate and moisture release rate regression curves were established and compared with those of ordinary viscose fiber. The results showed that the moisture absorption and release properties of different tencel fiber were different for their different processing processes. The moisture absorption equilibrium regain of tencel LF is 8.89%, tencel A100 is 11.44%, and tencel G100 is 10.33%. The moisture absorption ability of tencel A100 is the best, tencel G100 is the second, and tencel LF is the third. The moisture release equilibrium regain of tencel LF is 10.66%, tencel A100 14.12%, and tencel G100 11.47%. Moisture absorption, moisture release, and their rate regression curves are all close to exponential curves.
