This standard replaces FZ/T 12002-2006 “Combination Yarn for Combed Cotton True Yarn”. Compared with FZ/T 12002-2006, the main changes are as follows. --- Modify the third chapter classification, the 100m standard quality and standard dry quality calculations into Appendix A, delete the linear density Request content --- The linear density range was re-divided, and the strict single-variable coefficient of variation, linear density coefficient of variation (the original 100-meter weight coefficient of variation), etc. were added. The evaluation of the indicators, the uniformity of the assessment of dryness only preserves the coefficient of variation of the uniformity of dryness, and the index of coefficient of variation of the strand increases. --- Cancel the assessment of downgrade indicators, and assess according to the lowest one of the technical requirements; --- Sampling regulations were adjusted. This standard is proposed by the China Textile Industry Federation. This standard is under the jurisdiction of the National Textile Standardization Technical Committee Cotton Textile Subcommittee (SAC/TC209/SC10). This standard was drafted by Zhejiang Chunjiang Textile Group Co., Ltd., Fenghua Shuangduan Textile Canvas Industry Co., Ltd., and Shanghai Fangfang. Textile Industry Technical Supervision Institute, China Cotton Textile Industry Association. The main drafters of this standard. Chen Naiying, Jiang Jianqing, Wang Yunxia, Wang Yiyi, Ye Yuchun, Yi Jianshe. The previous versions of the standard replaced by this standard are. --- FZ/T 12002-1993, FZ/T 12002-2006.
