Inequality of Fabric Tensile Behaviour in Width

Abstract

Earlier experimental investigations have shown a particular regularity of warp projections inequality in the loom-state fabric width, while the projections of wefts were steady in the whole width of fabric. The changes of warp projections have high influence up on some properties of fabric. Variation of strength and elongation in warp direction in the fabric width is within the limits of error, while the variation of presented properties in weft direction is more signally. The reason of such phenomena can be the inequality of warp cross-section. So, the extension of specimens from different places in fabric width under the same loads is unequal. This means, that porosity of fabric under tension is different and herewith influences its filtration characteristics.
