纺织品 织物和制成品纺织品的接缝拉伸性能 第2部分：用抓样法测定接缝断裂的最大力（ISO 13935-2:2026）

[中文适用范围]： 本文件规定了当力垂直作用于缝线时，测定缝合缝最大张力的方法，所述方法称为抓样试验。本文件所述方法适用于机织物，包括因掺入弹性纤维、机械或化学处理而具有拉伸特性的织物，亦可用于其他工艺生产的织物。通常不适用于土工织物、非织造布、涂层面料、玻璃纤维织物及由碳纤维或聚烯烃扁丝纱线制成的织物。该方法仅适用于直线缝（由已缝制制品或织物试样制备），不适用于曲线缝（参见关于缝线考虑的附件B）。本方法限定使用恒定延伸速率（CRE）试验机。 [外文原描述]： This document specifies methods for the determination of seam maximum force of sewn seams when the force is applied perpendicularly to the seam. It describes the method known as the grab test. The method defined in this document is applicable to woven textile fabrics, including fabrics which exhibit stretch characteristics imparted by the presence of an elastomeric fibre, mechanical or chemical treatment. It can be applicable to fabrics produced by other techniques. It is normally not applicable to geotextiles, nonwovens, coated fabrics, textile-glass woven fabrics and fabrics made from carbon fibres or polyolefin tape yarns. [2] , [3] , [4] This method is applicable to straight seams only (obtained from previously sewn articles or prepared from fabric samples) and not to curved seams (see Annex B for considerations on seams). The method is restricted to the use of constant-rate-of-extension (CRE) testing machines.
