Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard was proposed by the China National Textile and Apparel Council. This standard is under the jurisdiction of the Basic Standards Subcommittee of the National Textile Standardization Technical Committee (SAC/TC209/SC1). The main drafting organizations of this standard. Shenzhen Changshuo New Textile Material Co., Ltd., Fujian Huafeng New Material Co., Ltd., Anhui Yuhua Textile Co., Ltd.

Textile fabric buckling deformation test method

1 Scope

This standard specifies three test methods for fabric arching deformation, namely constant pressure stretching method, constant elongation stretching method and tensile recovery method. This standard is mainly applicable to woven fabrics and knitted fabrics, other types of fabrics can be implemented by reference.

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Bagging When a certain area of the fabric is subjected to external forces, the surface of the fabric protrudes or swells. 3.2 Pre-setbaggingheight The specimen clamped in the flat state, after the half sphere is extended to the set height, the vertical between the specimen dome and the specimen clamping plane distance. 3.3 Pre-setpressurebaggingheight The specimen clamped in the flat state, after the half sphere is stretched to the set pressure, the vertical between the specimen dome and the specimen clamping plane distance. 3.4 Residual baggingheight After the specimen is arched to the set arch height or constant pressure arch height, and maintain a certain tension and relaxation recovery time, at a certain initial pressure or The vertical distance between the arch of the specimen and the center of the front plane of the specimen under the condition of displacement and stop pressure. 3.5 Residual rate of bagging The percentage of the ratio of the residual arch height to the set arch height or constant pressure arch height.

4 Principle

Clamp a sample of a certain size flatly in the ring clamping device, and use a hemisphere that simulates the size of the elbow to stretch the sample to be tested. At a certain height or a certain pressure value, the pressure load of the hemisphere is released after a certain period of time, and the specimen is restored for a certain period of time before arching The residual rate characterizes the arching deformation recovery ability of the sample in this period of time. ...
