超细纤维合成革透水汽性能的研究进展OACSTPCD

Microfiber synthetic leather is an ideal material to replace natural leather,but its water vapor permeability performance is still far from that of natural leather.The process of preparing microfiber leather was discussed in this paper,and the properties of microfiber leather and its deficiencies in water vapor permeability were analyzed.Specifically,the progress of research on the water vapor permeability of microfiber leather was discussed from the two main components of microfiber leather,namely microfiber leather base fabric and polyurethane resin.The modification of microfiber leather base fabric by hydrolysis,the addition of reactive groups and hydrophilic agents was summarized.The modification of polyurethane resin by filler,graft polymerization and co-blending was also discussed.Moreover,the modification of microfiber leather by finishing was discussed.Finally,the research direction for the water vapor permeability of microfiber leather was proposed.
