FZ/T 12001-2015Cotton rotor spun 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 12001-2006 "The spinning cotton yarn." this standard FZ/T 12001-2006 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 A, delete the line density to Demand content;

--- Technical requirements, increased one thousand meters Nep (280%) project, by deleting blackboard evenness projects retained evenness coefficient of variation the number of items;

--- Strong indicators into a single pile yarn, woven yarn, knitting yarn three large assessment;

--- Evenness variation coefficient of linear density coefficient of variation coefficient of variation of yarn breaking strength index tightened;

--- Yarn breaking strength, linear density deviation rate sub-optimal, one or two indicators;

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

--- Sampling provisions have been adjusted.

The standard proposed by China Textile Industry Association.

This standard by the National Standardization Technical Committee Textile Cotton Textiles Technical Committee (SAC/TC209/SC10) centralized.

This standard was drafted. Henan Xinye Textile Co., Ltd., Shandong Lichang Textile Technology Co., Ltd., Fenghua double shield textile canvas Industrial Co., Ltd., Zhejiang Spring Textile Group Co., Ltd., Zhejiang double up Textile Co., China Textile Industry Association, Shanghai Textile Industry Technology Authority.

3 Product classification, marking

3.1 spinning cotton yarn to the linear density of the classification.

3.2 The cotton yarn spinning raw cotton, code-named C, Fleece yarn codenamed Q.

3.3 The cotton yarn spinning marker, raw material before the code line density indicated, after the pile yarn line density indicated.

3.4 spinning to "OE" representation. Code should be marked in the raw material front.

Example. The yarn spinning cotton yarn napping density 27.8tex, should be written as OEC27.8texQ.
