Abstract:

Earlier experimental investigations have shown a particular regularity of warp projection inequality in the loom-state fabric width, while the projections of wefts were steady throughout the whole width of fabric. The changes in the warp projections have a great influence upon some fabric properties. The variation of elongation in warp direction in the fabric width is within the error limits, while the variation of the presented property in weft direction is more important. The reason for these phenomena is the inequality of warp cross-section. Tthe extension of specimens from different places in fabric width under the same loads is unequal. This means that the porosity of fabric in different places in a width under tension is differentalso, and thus influences its filtration characteristics.
