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 for standardization documents"
Drafting.
This document replaces GB/T 16603-2017 "Nylon Drawn Yarn". Compared with GB/T 16603-2017, except for structural adjustments and editorial changes,
In addition to the modifications, the main technical changes are as follows.
--- Changed the scope (see Chapter 1, Chapter 1 of the.2017 edition);
--- Changed the terms and definitions (see Chapter 3, Chapter 3 of the.2017 edition);
--- Change Table 1 to the performance items and indicators of nylon 6 drawn yarn, and change the linear density deviation rate and linear density variation coefficient
Linear density (CVb), coefficient of variation of breaking strength (CVb), coefficient of variation of breaking elongation (CVb), and linear density of strip unevenness (CV)
The selection range of the classification limit, the breaking strength index when the single-filament linear density (dpf) is >1.3dtex, and the center value of the breaking elongation (see
Table 1, Table 1 of the.2017 edition);
--- Added Table 2 performance items and indicators of nylon 66 drawn yarn (see Table 2);
--- Added technical requirements for oil content, network degree and titanium dioxide content (see 5.4, 5.5);
--- The appearance inspection test method has been changed (see 6.6.1, 6.7.1 and 6.7.2 of the.2017 edition);
--- Added online intelligent detection method (see 6.6.2);
--- Added oil content test items (see 7.2.1).
