Research on Improving the Physical Properties of Direct Spinning Superfiber Leather by Adding Fatting
Direct spinning ultrafine fiber synthetic leather is a natural imitation leather product prepared by impregnation process using direct spinning ultrafine and ultrashort polyester fiber non-woven material and water-based polyurethane as raw materials.In response to the problem of certain differences in the softness and hygiene performance between direct spinning ultrafine fiber synthetic leather and natural leather,several fatliquors were selected for post-treatment.The effects of different fatliquors on the softness and hygiene performance of direct spinning ultrafine fiber synthetic leather were studied.The results showed that the surface of the fibers in the direct spinning ultrafine fiber synthetic leather after fatliquoring was covered with an oil film,the mechanical strength and breathability remained basically unchanged compared to those without fatliquoring,and the softness increased by 91.5%and the moisture permeability increased by 27%.
