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.
