woven 34 reoriented 34 fabric constructions in accordance with the invention have extremely high elongation in the machine direction but very low elongation in the cross machine direction thereby resulting in excellent flexibility in the lengthwise direction of a finished v belt but good stability widthwise in this regard it has been found that the high flexibility and strength characteristics are achieved when the width is expanded in the range of 20 to 60 the elongation of the fabric is also high enough to prevent any interference with strength members such as rubberized cords that are incorporated in a typical construction with particular reference to fig1 of the drawings fig1 depicts a block flow diagram of the basic process steps for producing fiber loaded non woven fabrics according to the invention a preferred embodiment utilizes a non woven polyester starting material that has been subjected to a conventional needle punch operation to incorporate and 34 entangle 34 the chopped fibers within the fabric matrix as indicated above both conventional 34 chopped 34 fibers usually about 1 4 inch in length and staple length fibers may be used to form the fiber loaded fabrics and v belt constructions in accordance with the invention the staple length fibers may be standard polyester cotton fibers ranging in size from 1 2 inch to 11 2 inches within a preferred length of about 1 inch to 11 8 inches the 34 punched 34 fabric is then subjected to a first impregnation with a neoprene isocyanate solvent solution by immersing dipping the fabric into the solution it is then reimpregnated on both sides with a neoprene solvent composition using a standard textile pad the two impregnation steps place the chopped.
