FZ/T 12003-2014Viscose fiber grey yarn (English PDF)

Foreword

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

Instead of the standard FZ/T 12003-2006 "viscose yarn qualities." this standard FZ/T 12003-2006 compare the main changes are as follows.

--- Assessment of the product segments, increased Siro spinning,, yarn qualities compact Siro;

--- Revised Chapter 3 classification will be calculated 100m standards of quality and standards into the dry mass of Appendix B;

--- Modify product specifications nominal linear density range of categories and some assessment project name;

--- Evenness assessment retain only evenness coefficient of variation;

--- Breaking strength of the yarn, linear density deviation rate, evenness coefficient of variation, one hundred thousand meters of yarn faults and other indicators have been adjusted;

--- Increased one thousand meters neps assessment strand twist coefficient of variation;

--- Remove the twist factor range;

--- Increased hairiness H value as the reference value, added to the test method Appendix C "hairiness H value test method";

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

--- Change the original sample, adjusting the direct sampling of the finished product.

The standard proposed by China Textile Industry Association.

This standard by the National Technical Committee of Standardization Technical Committee printing and dyeing cotton textiles (SAC/TC209/SC2) centralized.

3 Product classification, marking

3.1 viscose fiber spun yarn qualities with different methods and linear density classification.

3.2 viscose yarn qualities of raw materials, code-named R.

3.3 front line density indicated yarn production process code, material code.

Example. a linear density of 18.5tex ordinary viscose fiber ring of the yarn, should be written as. R18.5tex.
