Study on pore characteristics and air permeability&moisture penetrability of warp-knitted jacquard shoe upper materials
In order to explore the correlation between the mesh structure design,fabric pore characteristics and the permeability and moisture permeability of the warp-knitted jacquard shoe upper materials,six shoe material samples with different structures were prepared according to the specific design diagram of the fabric.The pore characteristics of the fabric were described from the surface porosity,volume density and average pore diameter,and the influence on the permeability and moisture permeability of the shoe material was compared and analyzed.The results show that the increase of the proportion of thick tissue in the design will reduce the surface porosity of the fabric and increase the volume density,which will reduce the permeability and moisture permeability of the shoe material.The increase of the proportion of mesh structure will increase the surface porosity and decrease the bulk density of the fabric,thus enhancing its air permeability and moisture permeability.The permeability and moisture permeability of shoes with mesh structure design is significantly better than that without mesh structure design under the same fabric thickness,but the permeability and moisture permeability of shoes with larger average pore size under the same mesh proportion design is better.
