Shanghai Consumer Protection Committee Notified 2013 Leather Shoes Comparative Test Results

< p > the Shanghai Consumer Protection Committee has purchased 40 samples, involving 9 large department stores and 3 brand stores in the city, which basically cover the well-known high-end brands both at home and abroad, including 31 women's shoes, 9 men's shoes, 30 domestic products, 10 imported products, and the price ranges from 158 yuan to 2700 yuan.

< /p >

< p > after examination, the problems are mainly focused on the hooked core, sensory quality, peel strength and folding resistance of footwear.

Of the 40 samples, 27 were in line with the national standard requirements, with a coincidence rate of 67.5%; of the 30 domestic products, 20 were in line with the rate of 66.67%; 10 of the imported products met 7, and the coincidence rate was 70%.

The quality of products at home and abroad is basically the same.

On the other hand, from the price analysis, 6 of the 9 samples sold at a price above 1000 yuan were in line with the rate of 66.67%, and 21 of the 31 samples priced below 1000 yuan were in line with the rate of 67.74%.

This shows that price is not directly proportional to quality.

In addition, the residues of harmful substances such as < a href= "http://news.sjfzxm.com/news/list.aspx Classid=101112107105" > free formaldehyde > /a > six valent chromium were also detected, which was not optimistic.

< p > 1, test results and analysis < /p >

< p > 1, shoe steel hook heart < /p >.

< p > steel hooked heart involves human health, safety and the stability of footwear appearance. It needs high quality performance to keep the shoe shape and meet the comfortable demand.

It is installed between the sole and the bottom of the shoe, is the "backbone" of the shoe, plays an important bearing and balancing role, determines the stability of the shoes when wearing, especially for the quality of the middle and high heels.

In this test, 11 samples do not meet the requirements of the national compulsory standard. The problems are mainly focused on the steel hook mark, the lower limit of hook length, the longitudinal stiffness, the hardness of the hook core and the bending performance.

< /p >

< p > 2, sensory quality < /p >

< p > in order to standardize the commodity identification, the overall appearance requirements of the leather shoes standard must be marked with the Chinese shoe number in the shoe body, which can not only play an explicit role in the consumers, but also avoid confusion in the sales process and bring unnecessary trouble to the consumers.

In this experiment, there are 2 samples of foreign famous brands, namely, ladies' leather shoes, which are distributed by Fendi (Shanghai) Commercial Co., Ltd. (nominal trademarks: FENDI (Fendi), model: 814282 NEH FOQZO 235mm) and Boboli (Shanghai) Trading Co., Ltd. (women's leather shoes) (nominal trademarks: BURBERRY (Bo Baili), model: 38621061003/235mm) have not labeled the Chinese shoes numbers, which do not meet the standard requirements, indicating that these famous foreign brands need to be improved in carrying out the domestic product standards.

< /p >

< p > 3, peel strength < /p >

< p > peel strength is an important index to evaluate the bonding strength between shoe surface and sole.

The low strength products may open up during the process of wearing and storing, which directly affects the normal use of consumers. This is the main problem that causes consumers to complain.

In this test, 5 samples do not meet the standard requirements. For example, the peel strength of women's leather shoes (nominal trademark: TitiKaka, model: SL-TV131-CPP0884/235mm), which is made by Shanghai Xinghui Industrial Co., Ltd. is only 23 (N/cm) and 25 (N/cm) lower than that required by standard (40N/cm).

< /p >

< p > 4, folding resistance < /p >

< p > the flexural resistance of shoe sole material is the quality index for evaluating whether the shoes are durable.

If the folding resistance is not up to standard, it will produce cracks or break the bottom of the shoe, and glue the joint at the bottom to affect appearance and performance.

In this test, 1 samples did not meet the standard requirements, that is, the leather shoes (nominal trademark: TitiKaka, model: SL-TV131-CPP0884/235mm) produced by Shanghai Xinghui Industrial Co., Ltd. were found to have broken the bottom of the tested samples, which did not meet the standard requirements.

< /p >

< p > 5, hazardous substance < /p >

< p > the test also detected the possible residual toxic and harmful substances, free formaldehyde and six valent chromium, in leather shoes.

Due to the fact that the standards of leather shoes have not yet been provided for, the test provides only the measured data for consumers' reference.

< /p >

< p > free formaldehyde is a substance added to auxiliaries in the process of footwear production to achieve wrinkle resistance, stereotype, and durability of dyeing. It will gradually release when it is dressed. It can cause respiratory and skin inflammation through human respiratory tract and skin contact, and even induce cancer.

China's current national standard "limits on harmful substances in leather and fur" stipulates that the value of free formaldehyde in leather and textile products directly exposed to skin should be less than 75mg/kg.

Many consumers like to wear shoes barefoot, so too much formaldehyde is more likely to cause harm to the body.

The results of this experiment show that the measured values of free formaldehyde in some products are higher and the highest reaches 228mg/kg.

Brand manufacturers should be paid attention to.

< p > chromium can make leather soft and rich by 1. Do not trust the excessive publicity of merchants. Rational selection of anti UV clothing products should be based on their actual needs.

Many ordinary clothing also has UV protection properties.

The same clothing's UV protection performance is darker than that of light color. The fabric is thicker than the thin one, and the fabric structure is more compact than the loose one. Polyester and other synthetic fibers are better than natural fibers such as cotton and silk.

Elasticity, but the six valent chromium produced by oxidation under certain conditions is a harmful carcinogen to human body.

According to experts, excessive six valent chromium has a lethal effect on aquatic organisms.

The production of six valent chromium in leather shoes is mainly related to process technology. If we control well in the specific process operation, we can control the six valent chromium in a lower range.

It is understood that the state's current light industry standard < < a href= "http://news.sjfzxm.com/ > children's leather shoes < /a > has made a limit requirement for six valence chromium.

The results of this experiment show that the six valence chromium index of some products is high.

< /p >

< p > two, suggestions and opinions < /p >

< p > aiming at the problems found in this test, the Shanghai Consumer Protection Commission has informed the relevant enterprises of the test results, but some enterprises, especially some well-known foreign brands, have ignored them and have not made any positive responses.

In this case, the Commission recommends: < /p >

< p > 1, production enterprises should strengthen the study and implementation of standards, especially the national mandatory standards, and organize production strictly according to the standard requirements.

< /p >

< p > 2, the relevant standards making departments should revise and improve the relevant product standards as soon as possible, and incorporate the requirements of personal safety limits such as free formaldehyde and six valent chromium to protect consumers' health.

< /p >

< p > three, consumption tips < /p >

< p > Shanghai Consumer Protection Committee reminds consumers to pay attention to the following points when purchasing and wearing leather shoes: < /p >

< p > 1, when purchasing leather shoes, buy as much as possible to the department store or exclusive store, and keep the shopping voucher.

< /p >

< p > 2, not the most expensive, but for the right.

The different shapes of leather shoes differ from each other. The difference of just a few millimeters may give people a completely different feeling.

Choose the style that suits you. You'd better try it on when you buy it.

< /p >

< p > 3, leather material has good air permeability. It is recommended to see the logo on the shoe box when buying. Choose leather, lining and inner leather material are leather shoes, which will make the feet more comfortable.

< /p >

< p > 6. When wearing, pay attention to the classification of the product labels. If you are not directly exposed to skin, you should wear socks.

< /p >

< p > 7, shoes that are not worn for a long time should be packed into shoe last or stuffed into paper balls, so as to avoid shoe deformation and keep shoes dry.
