3 Requirements
3.1 Items
The requirements are divided into inherent quality and appearance quality, thereof, the inherent quality includes breadth, allowable weight tolerance/m2 ,ball bursting strength, size change rate by water washing, color fastness to light, color fastness to washing, color fastness to rubbing and fiber content; the appearance quality includes local defect and spread defect.
3.2 Grading requirements
3.2.1 The quality of warp knitted fake fur is divided into high-grade products, first-grade products and acceptable products.
3.2.2 For the quality grading of warp knitted fake fur, the inherent quality is graded according to batches while the appearance quality is graded according to bolts. According to combination of which, the minimum grade prevail.
3.3 Safety requirements
The products shall meet the requirements of GB 18401.
3.4 Inherent quality requirements
See Table 1.
