Longitudinal Sectioning of Cords and Fabrics

Abstract

A method is described for making longitudinal sections of multi-ply yarns, cords, and fabrics. Photomicrographs are presented to show the alignment of single fibers, yarns, and plies at various planes along a length of the material. The ar rangement of yarns and plies is compared in a ZZS- and ZSZ-twisted cord. Lon gitudinal slices through the thickness of a fabric are presented to show the internal contact of warp and filling yarns. The pictures reduce the interference normally presented by the thickness of the fabric.
