FZ/T 12007-2014Carded cotton and vinylon blended 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 12007-2005 "cotton blended yarn qualities dimension." this standard FZ/T 12007-2005 compare the main changes are as follows.

--- Adjust the standard name was changed to "carded cotton blended yarn qualities dimension";

--- 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. Zhejiang Spring Textile Group Co., Ltd., Qingdao Textiles Holding Corporation, China Textile Industry Association, Shanghai textile industry technical supervision.

3 Product classification, marking

3.1 carded dimensional qualities blended yarn blended ratio and linear density classification.

3.2 codenamed raw cotton as C, PVA is V.

Pub 3.3 fiber content to mass ratio, expressed as a specific content of cotton/PVA content.

3.4 front line density indicated yarn feed code, product blending ratio.

Example. The Victoria blended cotton yarn having a linear density of 18.5tex, cotton content of 65% polyvinyl alcohol content of 35%, should be written as. C/V65/3518.5tex.
