1 Scope

China's national standard for carded cotton wadding, applied together with Amendment 1 of 2021. Cotton wadding is the filling of a traditional quilt, and in China it is a product with a long history and a persistent quality problem. Carding opens and parallelises the fibres into a web, which is laid up into a batt; what matters to the buyer is that the batt is uniform, that it holds together, that it stays lofty and that it is made of what it claims to be. The last point is why the standard matters more than the product's simplicity suggests. Wadding is opaque, it is sold inside a cover, and adulterating it with recycled fibre from rags, medical waste or industrial waste has been a recurring scandal - the material sold as black-heart cotton. Specifying the fibre, the cleanliness and the physical properties, with test methods that will detect substitution, is the mechanism by which that is prevented, which is a different job from specifying a textile's performance.

This standard specifies the terms and definitions carding tire, product classification, requirements, test methods, inspection rules and instructions, packaging, transportation Lose, save This standard applies to the production and sale of combed tires.
