FZ/T 70001-2015Test methods of wool knitting yarn (English PDF)

Foreword

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

Instead of the standard FZ/T 70001-2003 "knitting and knitting wool test methods", compared with FZ/T 70001-2003, the major change of the following.

--- Adjusted normative references;

--- Standard atmospheric conditions according to GB/T 6529 execution;

--- Remove sample preparation in 4.3;

--- Test method modified as follows.

- Weight test to test quality;

- official moisture regain weight to official moisture regain quality;

- weight deviation rate to mass deviation rate;

- moisture regain to calculate the blended product according to GB 9994 execution;

- knitting yarn linear density of the test sample for each sample length requirements given in Table 1, line density symbol to Tt;

- increase the twist error rate calculation formula;

- increase the twist coefficient of variation is calculated;

- The powerful unit to cN cN;

- single yarn breaking strength formulas use letters;

- Remove the skein strength test method;

- To delete provisions formaldehyde content test according to GB/T 2912.1 executed;

- Delete a predetermined pH value test according to GB/T 7573 execution;

- To delete provisions washing dimensional change test according to FZ/T 70009 implementation;

- perspiration fastness test according to GB/T 3922 execution;

- increase the resistance to dry cleaning fastness tests prescribed by GB/T 5711 execution;

- original standard 5.20 rear injection to test sections on related thereto.

The standard proposed by China Textile Industry Association.

This standard by the National Standardization Technical Committee Textile Wool Textile Technical Committee (SAC/TC209/SC3) centralized.

This standard was drafted. Beijing Woolen Textile Institute of Science and test center, sweater Zhejiang Quality Inspection Center.

1 Scope
