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 Branch of the National Textile Standardization Technical Committee (SAC/TC209/SC1). This standard was drafted. Guangzhou Fiber Products Testing and Research Institute, Shenzhen Changshuo New Textile Materials Co., Ltd., China Textile Standard Inspection and Certification Shares Limited. The main drafters of this standard. Yang Xinhui, Liao Chunqiang, Deng Hua, Luo Jun, Yan Shuang, Xu Baiqing, Jiang Hong. Test method for low temperature folding resistance of coated fabrics

1 Scope

This standard specifies the test method for the folding resistance of coated fabrics under low temperature conditions. This standard applies to coated fabrics with a thickness of not more than 3 mm.

3 Principle

The one end of the sample is folded inwardly and clamped in the movable upper clamp, and then the sample is folded outward and the other end is turned downward and coated. Face-to-face, the lower end is clamped in the fixed lower fixture. In the specified low temperature environment, the upper clamp drives the specimen to move to the specified number of flexing times. Check the surface of the specimen for damage.

4 Terms and definitions

The following terms and definitions apply to this document. 4.1 Low temperature folding performance flexingresistanceatlowtemperature The material resists repeated flexing properties under low temperature conditions.

5 equipment

5.1 folding tester 5.1.1 Upper clamp consisting of a pair of flat metal plates rotating around the axis, see Figure 1. After the low temperature box (5.2) reaches the test temperature, the folding tester The upper clamp starts to make a round-trip flexion with a flexing angle of (22.5 ± 0.5) ° and a flexing frequency of (100 ± 5) times/min. 5.1.2 Lower clamp, which is a fixed fixture, on the same vertical plane as the upper clamp. When the upper clamp has a flexion angle of 0°, the lower edge of the upper clamp is The upper edge of the lower clamp is parallel and the vertical distance is (25 ± 1) mm. 5.1.3 Counter indicating the number of flexings. 5.2 Low temperature box It can accommodate the folding tester, the temperature can meet the test requirements, and the temperature deviation in the low temperature box should be controlled at ±2 °C. ...
