Foreword
This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1.Structure and Drafting Rules of Standardization Documents"
Drafting.
This document replaces FZ/T 12025-2011 "Low twist cotton yarn for wool warp". Compared with FZ/T 12025-2011, the main technical changes are
Change as follows.
---Adjusted the twist coefficient range of low-twist cotton natural yarn for wool warp (see Chapter 1, 3.2, Chapter 1, 3.2 of the.2011 edition);
---Adjusted the classification and marking of low-twist cotton natural yarn for wool warp (see Chapter 4, Chapter 4 of the.2011 edition);
---Added the requirements for the assessment of the kilometer neps (200%) of the low-twist cotton natural yarn used for the wool warp, and canceled the black board sliver uniformity
In view of the quality requirements, the linear density variation coefficient and the breaking strength requirements of second-class products have been improved (see Table 1, Table 2, and Table 1 of the.2011 edition.
Table 2);
---Canceled the sampling requirements for low-twist cotton natural yarns for wool warp (see Table 3 of the.2011 edition);
---Canceled the test requirements for the uniformity of the blackboard slats and the total number of particles of the blackboard neps (see Table 4 and Table 5 in the.2011 edition);
--- The presentation of the test results has been cancelled (see Table 6 in the.2011 edition).
