FZ/T 12004-2015Polyester and viscose 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 12004-2006 "Viscose blended yarn qualities." Compared with this standard FZ/T 12004-2006, the main technical changes are as follows.

--- The product segments, increased spinning, siro, compact sirospun and other content;

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

--- Deletion long yarn content, modify the nominal linear density range, adjusted some project name;

--- Technical requirements of technical specifications appropriate increase, increased one thousand meters Nep (200%) assessment index, evenness assessment indicators Retaining only evenness variation coefficient index;

--- Test Method added Appendix C hairiness H value test methods, and increased hairiness H value indicators;

--- Fiber content deviation included in the technical 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.

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. double Nantong Hong Textile Co., Ltd., Shanghai textile industry technical supervision, China Textile Industry Association, Texas Hengfeng Textile Co., Ltd. Zhejiang Spring Textile Group Co., Ltd., Changle City, Fujian Textile Co., Ltd..

3 Product classification, marking

3.1 polyester and viscose fiber blended yarn qualities of products in different spinning methods, blending ratio and linear density classification.

3.2 polyester and viscose fiber blended yarn qualities raw code. polyester T, the glue is R.

3.3 product blending ratio of Pub mass ratio, according to fiber content are listed in descending order, specifically expressed as. polyester mix ratio of 50% and to on to the content of polyester/viscose fiber content is expressed; polyester mix ratio below 50%, viscose fiber content/polyester content representation.

Example. Ring polyester and viscose fiber blended yarn qualities density 18.5tex, content 65% polyester, 35% viscose fiber, should be written as T/R65/35 18.5tex.
