Air slide belt fabric should be flat, uniform thickness, reducing the gap interface, sealing performance, and its geometry should not be errors. Air slide cloth should be uniform and stable, low resistance, energy saving, easy to install, easy maintenance. The air slide canvas running should not be delamination, do not collapse waist, can not afford to arch, do not leak powder, do not pollute the environment. Fabrics for air slides of tensile, compressive strength should be large, not stretching, deformation, wear resistance, high temperature resistance, corrosion resistance and long service life.
