Jiangsu Children's Shoes Sampling Report: 10 Batches Of Shoes Quality Is Not Qualified

Wear resistance is an indicator of easy wearing of shoes. It is also the core index of footwear detection. Lin Dongxiang, deputy director of the consumer goods inspection center of Nanjing quality inspection institute responsible for the test, said that wearing shoes with unwearable wear and wear will be severely worn out in normal wear and will greatly reduce the service life of shoes.

Have you noticed the bottom of your child's shoes? Do you have "high and low side" phenomenon on one side and high side? This may be the wear resistance of the sole is not up to standard.

It should be noted that wearing severe "high and low side" shoes for a long time will affect children's walking posture.

Yesterday, the Jiangsu Provincial Quality Supervision Bureau released.

It shows that in the 98 batches of samples tested, 10 batches of shoes are not qualified, and the main problem is that the wear resistance of the outsole of shoes is not up to standard.

Shoes are not wearable, wear high and low feet.

Mr. Su and his wife are usually busy with their work. There is not much time to take care of their children. The shoes of 10 year old sons are generally online shopping.

Recently, however, Mr. Su found that the child was not stable when walking, and he often had one foot high and one foot low.

At first, they thought it was a deliberate child. Later, when they looked at the children's shoes, they found that many shoes were high on one side and low on the side.

When he went to the hospital for a check, the hospital told Mr. Su that his child had already had slight high and low feet, and that the shoes that were not always suitable for peace were related, which made Mr. Su and his wife regret each other.

There are many problems with Mr. Su's children. "Many parents don't pay attention when they buy shoes for their children, which causes children to wear inappropriate shoes and affect walking."

Quality inspection report

Shoes do not wear well, children walk posture will be deformed.

The Quality Supervision Bureau of Jiangsu province collected 98 batches of samples and 88 qualified batches, with a pass rate of 89.8%.

There are 10 batches of unqualified products. The main problem is that the wear resistance of the outsole of shoes is not up to standard.

During the detection process, experts found that some shoes only grind for 5 minutes, the grinding wheel was completely caught in the sole, while the standard required grinding for 20 minutes.

Moreover, according to the standard, the wear marks should be less than 14 millimeters.

"Wear resistance is an indicator of whether the sole is easy to wear.

The core indicators.

Lin Dongxiang, deputy director of the consumer goods inspection center of Nanjing Quality Inspection Institute, who is responsible for the test, said that wearing the shoes whose wear resistance is not up to standard, the outsole will wear seriously in normal wear, greatly reducing the service life of shoes.

Not only that, the shoes that wear out may have a high side and low side. Children can easily balance when they walk. If they don't pay attention, they will fall down.

"Wearing for a long time may also make the child's walking posture deformed."

The wear resistance of the sole is very much related to the material quality.

According to Lin Dongxiang, the commonly used sole materials for travel shoes are rubber bottom, TPR bottom and EVA combination bottom.

Among them, EVA foam materials are widely used by enterprises because of their characteristics of light, soft and elastic. However, the wear resistance of this material is poor.

Some enterprises attach too much importance to the comfort of children's shoes. EVA is used too much in the sole materials, which leads to the wear-resisting performance can not meet the requirements.

Excessive lead can affect children's intelligence development.

Children's skin is tender, and their tolerance to heavy metals is weaker than adults, and their health is more susceptible.

The Provincial Quality Supervision Bureau also carried out the risk monitoring of 98 batches of children's shoes. It was found that two batches of samples had exceeded the standard lead content, and the "Card toot" sports shoes purchased in the Jingdong mall's maternal and infant franchise store had reached 156mg/kg.

The mandatory standard for children's shoes, which is to be implemented in January 1, 2016, is GB 30585-2014, "children's shoes safety technical specification", which stipulates that the total content of lead, arsenic and cadmium in children's shoes should not exceed 100mg/kg.

"When shoes are exposed to children for a long time, heavy metals tend to accumulate in the liver, bones, kidneys, heart and brain once the heavy metals are absorbed by the body. Toxicity will destroy or weaken the intelligence and central nervous function, and affect the intelligence of children."

Lin Dongxiang said.

Velcro is not "anti fatigue", it will not stick with it.

In order to dress conveniently, many parents will buy their children magic stickers shoes.

Velcro is also called sticky buckle, one side is tiny soft fiber, also called round wool, and the other side is the barbed hair of harder hook.

This time, 71 batches of shoes with Velcro were monitored. 5 batches of Velcro were unqualified after repeated opening and closing.

It is found that the shear strength of the buckle is relatively small before and after repeated opening and closing 5000 times, but the peel strength is relatively larger before and after repeated opening and closing 5000 times, and the peel strength is reduced by 55.5%.

After observing the appearance of the buckle strip before and after repeated opening and closing, it was found that the samples with lower amplitude were basically found to be prickly, twisted, and broken in the prickly part.

Analysis

The quality of online shopping and supermarkets is the worst.

The 98 batch of samples came from factories, shopping malls, supermarkets and online shopping platforms. From the results of spot checks, the products of supermarkets and online shopping channels generally had many problems, and the quality of products in production enterprises and shopping malls was relatively good.

"Now the supermarket competition is fierce, the quality of the product is often uneven, there are many small brands, the overall quality is relatively poor, the network business is more mixed up."

Lin Dongxiang said that the test results also showed that the qualified rate of products purchased from supermarkets and online was relatively low.

From the price point of view, the pass rate of children under 100 yuan is 84.9%, while the pass rate of children above 200 yuan is 100%.

This is mainly due to the low technical difficulty of children's shoes, and the main difference between prices is brand and design and materials.

How to buy children's shoes?

As sole as possible, choose rubber material.

When buying shoes, the sole material can not be too hard, too hard soles will affect the growth of children's feet, but they should not be too soft. The wear-resisting properties and the hardness of the soles of soft soles are not up to the requirements, affecting the wearing.

When buying, the rubber bottom is good, wear-resistant and skid resistant.

The pattern of the sole is rough, which is good for increasing friction and skid resistance.

In addition, the upper material is best for cotton and leather, because synthetic leather shoes have poor breathability.

The best size can be inserted into a little finger.

The child is in the growth stage, to choose the flat heel shoes, is conducive to maintain the normal arch, do not cause muscle and ligament damage.

When you buy shoes, how do you try size? "Loose fitting shoes can be inserted on the feet to insert a small finger."

Lin Dongxiang said, because the muscles and feet of children are tender and soft, and the narrow shoes will affect the development of the muscles and ligaments of the feet. Too much will affect walking and activities.

Don't choose shoes with longer shoelaces.

Children's shoes should be chosen as elastic or buckled. Children's shoes with longer shoelaces should not be chosen, because shoes with shoelaces are not only troublesome to wear shoes and take off shoes, but also if they are scattered and children will not fasten, it is easy to walk on foot and wrestle.

If you choose sticky belt type children's shoes, you can repeatedly open and close several times during the purchase, observe the quality of the buckle strap, and avoid the loosening and loosening of the sticky buttons in the movement process, which can cause danger.
