Recently, the commerce and Industry Department of Shanghai concentrates on organizing bras and vests for some supermarkets and shopping malls.

Underwear and other textiles were monitored for quality.

After testing, 13 batches of goods failed.

Problem 1: the pH value exceeds the standard, and there are 1 batches.

Because the surface of the human body is weakly acidic.

The pH value is too high or too low, which may destroy the pH balance of human skin, cause skin allergy or infection, and make the skin vulnerable to other pathogens.

It was found that the "JOCKEY" brand vest (model specification: L, XL, production date or batch number: J23242715214) was produced by the third branch of Shanghai (Xuhui) Fashion Trading Co., Ltd., which was sold by Xuhui branch of the Fashion Trading Co., Ltd., and the pH value was 9.2.

Question two: fiber content is not true, there are 12 batches. The measured value of fiber content of individual batches is obviously inconsistent with the nominal value. There is a phenomenon of random marking and shoddy.

It was found that the 2 batches of Kunshan run Hua Commercial Co., Ltd., Shanghai Zhabei branch, were named "Liang Meng", "White Magnolia" brand household clothing (model specification: 155/95A (M), 160/96A (L)), production date or batch number: B1210, (type specification: 165/108A, production date or batch number: B1208), and the fiber content (fabric) was labeled "cotton 60%, polyester 40%".

86.8%, cotton 13.2% "," polyester fiber (polyester) 89.3%, cotton 10.7% ".

The commerce and industry department reminds consumers that when choosing underwear, they should see the identification of the commodity, and the best choice is natural fiber products, of which the cotton products are more suitable.

In terms of color, it is best to choose natural or light colors. Try not to choose deep red, purple, Navy, brown, dark green and black. White may also be added with fluorescent whitening agents.
