标准摘要
[中文适用范围]： 此文件规定了确定非织造布弯曲长度的方法。给出了从弯曲长度计算非织造布材料的弯曲刚度的公式。该方法不适用于可能具有自然扭曲的组合型材料（复合材料或层压材料）。注 本文件描述了一种专门针对非织造布的试验方法。 [外文原描述]： This document specifies a method for determining the bending length of a nonwoven. A formula is given for calculating the flexural rigidity of the nonwoven material from the bending length. The method is not applicable to combination-type materials (composites or laminates) in which there can be a natural twist. NOTE This document describes a test method specific to nonwovens.
