| Popis: | The main content in the paper aims to characterize the moisture transfer property of polytetrafluoroethylene (PTFE)/polyethylene terephthalate (PET) bi-layer complex fabric. Firstly, theoretical analyses of moisture permeability from the moisture transfer cup method and moisture resistance from the moisture resistance method were conducted, and the function between the two indexes was acquired. Results show that there is a negative correlation between moisture permeability and moisture resistance. The higher the moisture permeability of the fabric, the lower the moisture resistance. Then, in order to study relationship between moisture permeability and resistance, several PTFE/PET bi-layer complex fabrics were prepared, and a theoretical model of moisture resistance was constructed by the serial method so as to evaluate the relationship of the moisture transfer property between complex fabric and two components (PTFE film and PET fabric). Comparisons between theoretical and experimental results of moisture resistance of complex fabric were conducted, which demonstrated that the serial model was effective in characterizing the moisture transfer property of complex fabric assembled by membrane and fabric. |
