Investigation of Water Permeability of Thermoplastic Polyurethane (TPU) Electrospun Porous Mat
The aim of this study is to form thermoplastic polyurethane (TPU) mats by electrospinning process on knitted and woven materials, and to determine the water permeability of textile materials before and after mat has been formed on them. TPU granules were dissolved in a mixture of dimethylformamide (...
