中文名称：纺织品 强制机械膨胀法测定织物变形性
英文名称：Textiles — Determination of fabric deformability by forced mechanical distension
发布日期：2020-12
标准范围
This document specifies a method for the automatic determination of the deformability of textile fabrics,
including continuous-fibre reinforcement textiles. This method is not applicable to resin impregnated
fabrics.
The method is suitable for use with fabrics such as woven or knitted fabrics, nonwovens, non-crimp
fabrics, fabrics made of glass rovings or untwisted carbon filament yarns intended for reinforced
composite materials. When applying the method to multi-axial non-crimp fabrics, the evaluation of the
fibre orientation and gaps only incorporates the uppermost layer.
The method can be used for fabrics treated with powder binder.
