Seam shift resistance with fixed seam opening
DIN EN ISO 13936-1, Textiles – Determination of sliding resistance of yarns in fabric seams – Part 1: Method with specified seam opening
The method is used to determine the force required to open a seam in a fabric, e.g. 4 mm. This method is not suitable for highly stretchable or technical fabrics. The seam sliding strength results in either a warp thread or weft thread shift.
