Abstract:

In order to further improve the water-vapor transmission rate and softness of polyester/polyamide 6 (PET/PA6) hollow microfiber synthetic leather base, polyacrylonitrile (PAN) nanofibers were mixed with PET/PA6 microfibers to prepare PAN-PET/PA6 micro/nano microfiber synthetic leather base by hydro-entanglement and alkali treatment. The effects of PAN nanofiber mass fraction on the air permeability, water vapor permeability, moisture absorption, softness and mechanical properties of leather base were analyzed. The results show that the water vapor permeability, moisture absorption, softness and tear strength were improved with the content of PAN nanofibers increase for the same areal density, but the air permeability and breaking strength were decreased. When the content of nanofibers was 20%, the water vapor permeability of the base was increased by 15.19%, the moisture absorption 23.53%, and the softness was increased by 38.17%. After alkali treatment, the hydrophilicity of base was obviously improved. The water vapor permeability was increased by 23.81%, the moisture absorption was increased by 42.26%, and the softness was increased by 23.20%.

Key words: polyester/polyamide 6 microfiber, polyacrylonitrile nanofiber, spunlace, synthetic leather base, fiber modification, moisture permeability
