Abstract
Abstract A material for use in agricultural belting. The material includes a center ply fabric with a relative resistance to stretching, and two outer fabric plies in spaced relation to the center ply, these outer fabric plies offering less resistance to stretching, but a greater flex fatigue life, than the fabric of the center ply. The outer fabric plies include fill yarns including extruded monofilament yarns which impart relative transverse stiffness to the material.
