According to the standard GB/T 4745-2012"Textile waterproof performance testing and evaluation-Water Wetting Law",the surface moisture resistance of fabrics treated with fluorocarbon waterproof finishing agents and fluorine-free waterproof finishes is tested.By controlling the humidity control time,test water temperature,washing method,drying method and drying time,the influence of such test conditions on the moisture resistance test results of the surface of waterproof finishing fabrics is analyzed.The results show that the humidity control time,test water temperature and drying time have little effect on the surface moisture resistance of the waterproof finishing fabric.The washing method has a certain impact on the moisture resistance of the surface of the waterproof finishing fabric;The drying method has the greatest impact;The surface moisture resistance of the same waterproof finishing fabric is ranked as flipping drying＞hanging drying in the drying room ≥hanging drying in natural environment.
