Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. Instead of the standard FZ/T 50002-1991 "Test method for chemical fiber shaped." Compared with the standard FZ/T 50002-1991 The main changes are as follows. --- Remove the average radial degree of profile, radial profiled theory, relative shaped cross section, average cross-sectional contour of the theoretical cross-section profiled degree Test items; --- Modification of relative radial shaped, hollow calculation formula; --- Increasing the cross-sectional contour, perimeter coefficient, hollow perimeter coefficient, specific geometry test items; --- Increased production method slicer sample; --- Remove indicator selection principle, precision data, Appendix A; --- Adjust the number of measurements, modify the final result of the calculation methods. The standard proposed by China Textile Industry Association. This standard by the Shanghai textile industry technical supervision of the centralized. This standard was drafted. Shanghai textile industry technical supervision, Tong Kun Group Co., Ltd., Jiangsu Shenghong Science and Technology Company Limited Secretary, Tianjin Polytechnic University, Shandong Yami Technology Limited, Textile Industry Research Institute of Standardization. The main drafters of this standard. De Zhou Zhen, Wang Lili, Sun Yanlin, Liu Shuhua, Yincui Yu, Xing Chunhua Fang Xijiang. This standard replaces the standards previously issued as follows. --- FZ/T 50002-1991. Test methods for chemical fiber shaped degree

1 Scope

This standard specifies the method for determination of parameters of profiled fiber cross-sectional shape. This standard applies to all kinds of shaped fibers can be clearly imaged.
