On July 1, 2017, the China National Standardization Technical Committee for Apparel implemented an updated version of GB/T 22700 – Washed garments. The new version, GB/T 22700-2016, replaces GB/T 22700-2008.
The standard has been updated to meet the current expectations concerning product quality, with the intention that they will create standardization regarding production, sales and marketing.
GB/T 22700-2016 covers washed garments that are mainly made from woven fabrics but it does not apply to denim wear and clothing for infants (36-months or under). The standard defines washed garments as those which are processed by one or more washing methods – stonewash, sand wash, enzyme wash, bleach wash, snow wash, etc. It applies whether the washing process was done on a finished garment, semi-finished garment or before manufacture has started, i.e. the fabric stage.
The new version of the standard contains a number of technical revisions, including updates for:
- Instructions for use
- Provision of raw materials, stripe matching, plaid matching, sewing rules, ironing
- Requirements for physical and chemical properties, testing method, colorfastness to dye transfer, finished products and quality defect for finished products
In addition, the updated version has deleted provisions for stitching fabrics, tolerance specification and deviation, and the test method for seam slippage.
For a more detailed assessment of the changes, see Safeguard 129/17.
Stakeholders are advised to now review GB/T 22700-2016, to make sure their products remain compliant.
