Abstract:
1. A method of making a nonwoven fabric having substantially parallel yarns aligned in a warp direction comprising the steps of: aligning the yarns in a warp direction through spaces defined between two sets of rollers, while the rollers are driven at a roll face speed faster than a linear speed of the yarns, wherein a first roller within each of the two sets of rollers is provided with a surface texture that is coarser than a second roller within each of the two sets of rollers, and wherein the yarns engage each of the first rollers prior to engaging each of the second rollers while moving in the warp direction; and applying an adhesive coating to one side of the aligned yarns to form a cohesive web of substantially parallel yarns.
