FZ/T 12013-2014Lyocell 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 12013-2005 "lyocell yarn qualities." this standard FZ/T 12013-2005 compare the main changes are as follows.

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

--- The technical requirements, the adjustment range of the nominal linear density, modify the name of part of the project, evenness assessment retain only evenness Coefficient of variation;

--- Coefficient of variation of breaking strength, linear density coefficient of variation, evenness variation coefficient and other indicators have been adjusted;

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

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.

This standard was drafted. Qilu Hong Textile Group Co., Ltd., Shanghai textile industry technical supervision, the mayor of Changle in Fujian spinning source Weaving Limited, Qingdao Textiles Holding Corporation, China Textile Industry Association.
