ASTM D434 standard published by the American Society for Testing and Materials (ASTM), This test method covers the determination of the resistance of filler threads to shear over the warp threads or the warp threads using a standard sewing threads. The test method is not designed for upholstery fabrics.
The load-elongation curve of the fabric is superimposed on a load-elongation curve of the same fabric as a standard stitch sewn parallel to the yarns tested. The resistance to yarn slippage is reported as the load at which a certain size slip occurs.
Since this standard is widely used in commerce for acceptance testing, it is considered satisfactory for acceptance testing. In the event of disagreement arising from differences in values reported by the buyer and seller when using this test method for acceptance testing, the statistical deviation, if any, between the buyer's laboratory and the seller's laboratory should be determined by each comparison. based on test samples taken randomly from a sample of material of the type under consideration.
This test method is used as an indicator of the tendency of threads to slip in a stitch. Such slippage causes a garment fault in a seam that cannot be easily repaired by re-stitching.
Our organization also provides testing services within the scope of the test standard for the resistance of yarns in woven fabrics against slipping, using ASTM D434 standard stitching, within the framework of laboratory testing services.
