Research progress on moisture permeability and air permeability of microfiber synthetic leather
Microfiber synthetic leather(microfiber leather)is an ideal alternative to natural leather.The structural difference leads to a few drawbacks in moisture permeability and air permeability between microfiber leather and natural leather.The structure and composition of microfiber leather were introduced,the influencing factors and improving measures of its moisture permeability and air permeability were analyzed,the effects of base modification,polyurethane film modification and sizing on the moisture permeability and air permeability of microfiber leather were expounded.Finally,the advantages and disadvantages of current modification methods of microfiber leather were summarized,and the prospect of further research on improvement of moisture permeability and air permeability of microfiber leather was put forward.
