how that the optimum Р preparation conditions of PBAT microporous membrane are as follows , the concentration of casting solution is Р 14.34%, the pre-evaporation time is 44.63 s and the membrane thickness is 0.16 mm. The mechanical propert ies Р and hydrostatic pressure resistance of the composite material with the optimal p rocess are larger than those of Р spunlaced nonwovens, the pore diameter and moisture permeability are smaller than those of nonwovens. The Р contact angle is slightly smaller than that of nonwovens.
