Foreword

Instead of the standard FZ/T 32007-2000 "spinning ramie blended yarn of the present." the main changes in the standard of FZ/T 32007-2000 compared as follows.

--- Remove the range ramie content of 50% or more of the restrictions, widening the scope of the standard;

--- Remove the common ramie blended yarn moisture regain table;

--- Remove the nominal weight of the standard provisions of the Turks and series table;

--- Adds a special file fine yarn assessment;

--- Cancel indicators along the lower assessment, according to the minimum assessment of a product, etc;

--- The fiber content included grading assessment indicators, not included in the reference index for the technical requirements twist factor table;

--- Improving the assessment index weight coefficient of variation of one hundred meters and yarn breaking strength;

--- Increasing the representation of the test results.
