Recently, Quality and Technical Supervision, Hangzhou, Hangzhou, production organization of Bedclothes (quilt cover, bed sheets) to carry out the monitoring sample, 17 companies were taken for 32 batches of products produced on the Bedclothes the fiber content, formaldehyde content, pH, , odor, biodegradable aromatic amine dyes, appearance quality, breaking strength, dimensional change rate of washing, color fastness, product identification and other indicators tested, the results of 27 batch pass, pass rate 84.4%.
      The main problems: First, color fastness project is not up to total 3 batches. Showed resistance to dry friction, moisture friction, perspiration and light fastness of failure. Color fastness, the product is washable, abrasion performance, color fastness and poor product encountered in the course of the sweat, the fabric will fall off faded paint, dye molecules and metal ions are likely to be through the skin Human skin absorption and harm to human health, also may contaminate other clothing. The main reason is the fabric dyeing and finishing plant dyes or dyeing process on the improper and floating color wash after dyeing is not the net result. Second, a batch of quilt pH value exceeded. Human skin neutral weak acid, direct contact with high or low PH value of the fabric, cause skin irritation. pH, failed mainly due to the pH control fabric finishing process used improperly or printing quality poor, not the after-cleaning process. Third, a batch specification sheets for the label does not match the physical size and sentenced to unqualified products.
