FZ/T 13024-2020Meta-aramidgrey fabric (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces FZ/T 13024-2011 "Aramid 1313 Natural Fabric". Major technical changes compared with FZ/T 13024-2011 as follows.

---Added the logo content (see 3.2);

---The name of the original intrinsic quality width, density, and breaking strength assessment items is adjusted to width deviation rate, density deviation rate, and breaking strength deviation Rate (see 4.1, 4.1 in the 2011 edition).

---The quality deviation rate assessment items per unit area have been added, and the neps defect grid rate assessment items have been deleted (see Table 1, 2011 version of the

Table 1);

---The second-class fabric weave is adjusted to meet the design requirements, the density deviation rate is adjusted to positive and negative deviations, and the tearing strength is assessed in two levels (see

Table 1, Table 1 of the 2011 edition);

---The allowable number of ratings for fabric defects was changed from points/m2 to points/100m2, and the first-class and second-class product evaluation indicators (see

Table 2, Table 2 of the 2011 edition);

--- Delete the original Appendix B and Appendix C (see Appendix B and Appendix C in the 2011 edition).

This standard was proposed by the China National Textile and Apparel Council.

This standard is under the jurisdiction of the Cotton Textile Subcommittee of the National Textile Standardization Technical Committee (SAC/TC209/SC10).
