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" drafted.

This document replaces FZ/T 14022-2012 "Aramid 1313 Printing and Dyeing Cloth". Compared with FZ/T 14022-2012, the main technical changes as follows.

---The name of the file is changed to "Meta-Aramid Printing and Dyeing Cloth";

--- Expanded the scope;

---Intrinsic quality has added the quality deviation rate per unit area assessment item, the weft density deviation rate has been adjusted to positive and negative deviations, and some color fastnesses have been adjusted Degree assessment indicators (see Table 1);

---The appearance quality is written in accordance with the width deviation, color difference, skew, local defects and scattered defects, and the local defects and local defects are deleted.

Partial fabric defect score description and content of defect meter (see 5.4.1, 5.4.2, 5.4.3, 5.4.5 of the 2012 edition);

--- The allowable scoring of local defects stipulates that the assessment is based on points per 100 square meters and the assessment indicators have been improved (see Table 2, Table 3 of the 2012 edition);

---Improved the chromatic aberration assessment index, and the skewness shall be assessed according to the stripe pattern or stripe weft, pattern or weft (see Table 2, 2012 edition).

of table 4);

--- Deleted the appearance quality inspection conditions and methods (see 6.2 of the 2012 edition).
