Fiber content, formaldehyde content, PH value, color fastness to water, color fastness to rubbing, and product identification are the most important indicators for judging the quality of clothing. On December 23, it was learned from the Provincial Quality Supervision Bureau that the provincial quality supervision department sampled 80 batches of T-shirts, knitwear, trousers, tops and other types of apparel products distributed by 67 circulation enterprises in Lanzhou in the third quarter. Among them, 58 batches of 48 companies were qualified, and the qualified rate of product sampling inspection was 72.5%. Nearly 30% of the garments were unqualified, which was 9.1 percentage points lower than the same period in 2009.
