Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. Instead of the standard FZ/T 50007-1994 "Spandex elasticity test methods." This standard FZ/T 50007-1994 compared to the main changes are as follows. --- An increase of 300% elastic recovery test method; --- Remove the load test method specified elongation; --- Deleted Appendix A specimen holding method; --- Modify pre tension calculation methods; --- Stress relaxation test method, remove the stress relaxation rate between 30s ~ 5min; --- Modify the tensile cycles; --- 300% proof test method, stress relaxation test methods and test methods for plastic deformation recovery rate combined into one chapter; --- 300% increase in the average elastic recovery rate, stress relaxation rate is calculated the average value of the average and the rate of plastic deformation. The standard proposed by China Textile Industry Association. This standard by the Shanghai textile industry technical supervision of the centralized. This standard was drafted. Textile Standard (Beijing) Inspection and Certification Center Co., Ltd., Zhejiang Huafeng Spandex Co., Ltd., Yantai Taihe new Materials Co., Ltd., Shanghai textile industry technical supervision. The main drafters of this standard. Wang Shaohui, Fang Xijiang, Zhao Xiaoyang, Shaozheng Li, Zhou Zhen Germany. This standard was first published in 1994, this is the first revision. Spandex elasticity test method

1 Scope

3 Terms and Definitions

GB/T 3291.1, GB/T 3291.3 and GB/T 4146.1 and define the following terms and definitions apply to this document. 3.1 Elongation cycle cycleelongation Stretching reply cycle maximum elongation. 3.2 Reply stretching cycle tensilerecoverycirculation No loose clamps, without interruption at a predetermined starting length and stretch speed to stretch the sample after the selected cycle elongation, and then return to the starting The length of the cycle process. 3.3 Stress relaxation stressrelaxation At a constant temperature, to maintain a given deformation, internal stress fibers increases gradually with time decay phenomenon. 3.4 Stress relaxation rate stressdecayrate The ratio of the stress applied to the sample, expressed as a percentage when the amount of stress relaxation and stress relaxation tests begin. 3.5 Plastic deformation plasticdeformation Stretched specimen after the removal of the external force generated by the deformed portion can not be reinstated. 3.6 Plastic deformation rate plasticdeformationrate Plastic deformation of the original length ratio, expressed as a percentage.
