The results indicated that the water vapor permeability was improved by 27% by formic acid hydrolysis,the water vapor permeability was improved by 31% by triethanolamine hydrolysis,the water vapor permeability was improved by 32% by protease hydrolysis,the water vapor permeability was improved by 30% by pancreatic hyd.

The air permeability,water vapor permeability,and softness of samples from different positions and directions of goatskin and sheepskin clothing leather are tested,in order to provide scientific data for standardization and rational use of leather in leather goods factories,as well as to provide guidance for adjustments and regulations on tannery technology.
