The city quality and Technical Supervision Bureau recently conducted spot checks on the silk products in the market. It found that 18 batches of the 38 batches of products were unqualified, which involved problems such as pH value exceeding standard, fiber content, filler quality deviation rate, oil content of filler, instructions for use (labels) and quality of filling materials.

Among them, the pure 200cmx230cm mulberry silk produced by Guangzhou three and textile products Co., Ltd. was found to be pH unqualified.

Yesterday, we visited the local market and found that the above substandard products were still on sale.

Experts say the pH value of textiles is determined by testing the pH value of textile water extract.

In the process of textile printing and dyeing, if the agents are not adequately washed or neutralized, the fabric is highly acidic and alkaline, exceeding the pH value of the human skin. It will stimulate and corrode the human skin and cause damage to the sweat gland system and nervous system of the human body.

The pH value project was not qualified, and the "ELLE DECO" natural Meyer silk quilt (150cm * 225cm) produced by the nominal Cost household products (Shenzhen) Co., Ltd., and the "cat home textiles" pure cotton silkworm filament produced by the Shanghai Shanghai world bedding Co., Ltd., sold by the new world Limited by Share Ltd, were (160 * 210cm: V46484).
