Abstract
Woven industrial fabrics which have an air permeability of at least 200 cfm per square foot under a pressure differential of 0.5 inches of water are described. These fabrics contain finned weft fibers with a shape factor of 2.5 to 5.0 and a distortion index of less than 35. Improved fabric stability and a significant reduction in weft fiber denier are achieved.
