Frequent formaldehyde exceeds standard and pH value exceeds standard.

Yesterday at a seminar on underwear in Wuhan, Wang Zhi, director of the expert technical committee of the China knitwear industry association, revealed that the failure of big underwear was not unusual. The reason was Jerry building and insufficient washing times.

"Formaldehyde, pH value and color fastness are all old problems for underwear."

Wang Zhi told reporters, "before, we do not pay much attention to these problems, with the improvement of living standards, consumers increasingly pay attention to the safety of underwear.

In fact, formaldehyde and other problems, as long as the number of water washing enough, can be completely solved, the loopholes now is that enterprises do not follow the procedures completely.

Data show that in 2011, the output value of China's knitting enterprises above designated size was 576 billion 500 million yuan, up 21% over the same period last year.

But knitted apparel exports 20 billion 750 million pieces year-on-year, down 0.4% compared to the same period, the first decline since 2000.

This means that the competition in the underwear market is becoming increasingly fierce.

Many functional underwear are empty, and have been playing "safety card".

Wang Zhi introduced: "the state also attaches great importance to it.

Norms.

At present, the more reliable underwear functions include thermal insulation, dehumidification, antibacterial and magnetic properties, all of which have national standards, such as keeping the warmth rate above 30%.

Nowadays, a kind of "skin care" underwear, which uses biological agents such as collagen instead of synthetic agents, is beginning to appear.

Jie Zhiwei, the brand director of pure underwear company, said: "this underwear is made of zero formaldehyde material, collagen has cosmetic effect, and the principle is the same as cosmetics."

Wang Zhi said: "collagen as an underwear" finishing agent ", originated in Europe and America, Japan and other places.

In the past, many functional underwear were suspected of hype.

When consumers choose to purchase, the first thing is whether they have reached the target or not. Two, we need to see whether there is material substance in the inspection.
