Foreword

GB/T 23319 "after washing textiles skew determination" is divided into three sections.

--- Part 1. knitwear wale skew changes;

--- Part 2. woven and knitted fabrics;

--- Part 3. woven garments and knitwear.

This is Part 1 GB/T 23319 of.

This section identical with ISO 16322-1:2005 "after washing textiles skew measurement - Part 1. knitwear wale skew the rate of change "(in English).

This portion of the ISO 16322-1:2005 has the following differences compared to.

--- Normative references cited in our national standards with ISO standards consistent technical content;

--- Deleted international standards foreword;

--- Modify 8.9 test procedure is repeated for the 8.1 to 8.5;

--- Increased Chapter 9 note.

This part is proposed by the China Textile Industry Association.

This part of the National Standardization Technical Committee on Basic Standards Subcommittee Textiles (SAC/TC209/SC1) centralized.

This section is drafted. Hangzhou Quality and Technical Supervision and Inspection Institute, the National Textile Products Quality Supervision and Inspection Center inspection, Textile Standard (Beijing) check Inspection and Certification Center Co., Ltd.

1 Scope

This section GB/T 23319 specifies the test skew rate in the flat knitting machine needle shaped weft knitted garment washed after change method.

The test results obtained by different methods may not be comparable.

Calculated skew skew angle changes by measuring the front knitted garment washing and after washing.
