Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

Instead of the standard FZ/T 12006-1998 "combed cotton polyester blended yarn qualities," compared with FZ/T 12006-1998, Technical Changes as follows.

--- Revised Chapter 3 classification will be calculated 100m standards of quality and standards into the dry mass of Appendix A, delete the line density to Demand content;

--- Fiber content deviation included in the technical requirements;

--- Redrawing the tables cotton content ranges;

--- Project name "one hundred meters weight coefficient of variation," "one hundred meters weight deviation" were changed to "linear density coefficient of variation", "linear density bias Slip ";

--- Requires an appropriate increase in the technical specifications, while adding one thousand meters neps (200%), kilometers thick section (50%), kilometers details (-50%) Quality indicators, canceled blackboard Nep grains assessment requirements;

--- Cancel indicators along the lower assessment, according to the technical requirements of the products, such as a minimum assessment;

--- Sampling provisions have been adjusted.
