纺织品.机织物的双轴拉伸性能.用抓取法测定最大力和最大力下的伸长率

[中文适用范围]： 本文件规定了在双轴试验机中使用抓取法测定纺织织物的最大力和最大力伸长率的程序。 该方法主要适用于机织织物，包括表现出通过弹性纤维的存在、机械或化学处理而赋予的拉伸特性的织物。 它也适用于其他工艺生产的织物。 它不适用于土工织物[4]、非织造布[3]、涂层织物[5]、纺织玻璃机织物[2]以及碳纤维或聚烯烃扁丝制成的织物。 该方法仅限于在同一轴上使用恒定延伸率 (CRE) 测试机。 [外文原描述]： This document specifies a procedure to determine the maximum force and elongation at maximum force of textiles woven fabrics using a grab method in the biaxial testing machine. The method is mainly 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 not applicable to geotextiles [ 4 ] , nonwovens [3] , coated fabrics [5] , textile-glass woven fabrics [2] , and fabrics made from carbon fibres or polyolefin tape yarns. The method is restricted to the use of constant rate of extension (CRE) testing machines to the same axis.
