Guangzhou City Commerce And Industry Bureau'S Spot Checks Showed That The Quality Of Shoes Is Still Grim.

In 2015, the Guangzhou industrial and Commercial Bureau conducted a quality check on the footwear products sold in the circulation sector of Guangzhou, and extracted 70 samples from 41 production enterprises.

After inspection, the quality of 15 samples is not qualified, and the rate of physical quality failure is 21.43%.

Among them, the unqualified products are "OK NG NG AOKANG" brand men's single shoes produced by Zhejiang AOKANG shoe Limited by Share Ltd (the nominal production unit), and the "BEITA Kun Bei Bei" women's casual shoes produced by the Beite Sports Products Co., Ltd. (nominal production units).

At present, the Guangzhou industry and Commerce Bureau has punished the sellers of unqualified commodities according to the relevant provisions of the product quality law, and urged the sellers in the city to do the work of the lower shelves of the same producers with the same trademark and the same specification and unqualified products.

The sampling inspection adopted the "

The sample of supervised sample inspection procedures with a priori quality information "(GB/T 28863-2012) is used to supervise the collection of the same trademark and the same type of products that are sold by the same producers in Guangdong province in the circulation field.

The quality commitment is aimed at the current safety indicators of the public and the main performance indicators of the product. The items including free formaldehyde, decomposable harmful aromatic amine dyes, peel strength at the bottom, adhesion strength at the outside and bottom, wear resistance of the shoe, shoe heel strength, heel pull strength, hook bending rigidity, hook hardness, bottom sole hardness, outer bottom tensile strength, outsole elongation, outsole wear, outsole hardness, outsole density, whole shoe flexing performance, the thickness of the top and the upper part, the thickness of the front part, the thickness of the bottom plate and the thickest thickness of the rear palm are measured. The sampling inspection is based on the national mandatory standards for footwear commodities, the enterprise standards adopted in the packaging of commodities, or the enterprises.

The folding resistance is an index to evaluate whether the sole of shoes is easy to break, whether the surface material is easy to crack, whether to split the pulp and whether the bottom is easy to be opened. It directly reflects the flexural flexibility of the sides and the bottom and the fastness of the bottom.

It is a comprehensive quality index for the wearing life of footwear products. The shoes with unfolding and unqualified performance are prone to break the soles, break the surface, split the surface or help the bottom and glue the bottom wall during the wearing process.

There are three main reasons for the failure of folding resistance.

In the process of outsole production, too much filler and low rubber content will cause the rubber outsole to become hard and brittle, lack of toughness and easy to crack. Two, it is hard to bond the surface with the backing. It may use the poor adhesive or glue binding process to control the unfinished parts and cause the rubber parts to be glued.

When leather shoes or leather sandals are worn, the gravity of the human body is concentrated on the heels. If the heel hardness is not enough, the whole pair of shoes can not support them, which is likely to cause users to twist their feet.

The hardness of the forming shoe heel is mainly due to the poor quality of the material used in the sole.

The center of the waist is positioned between the bottom of the shoe and the bottom of the outer middle, and plays the role of "big beam", supporting and maintaining the overall shape of the shoe.

The assessment indexes include longitudinal rigidity and hook hardness.

The hardness of the hook is not qualified, it is easy to cause the whole deformation of the shoes, wearing instability, and even when the foot is sprained, it falls down.

The main reason for the failure of the project is that the quality of the steel made of steel core is not good enough, which leads to soft core and too low rigidity.

Remind consumers to first look at the bags and upper materials when choosing, try to choose the logo (logo) complete products.

Second, look at the shoes and the box on the shoe and the shoe type, recognize whether it is consistent with your own requirements, annotated or unlabeled as far as possible not to buy.

When buying, smell the shoes first. If irritating smell is very serious, you should be careful to buy, try to buy some shoes with no smell or less smell.

Check the upper sewn suture and the bottom seam to check if there is a broken line, whether the upper suture is neat, whether the adhesive is bonded to the bottom, whether it is smooth, no ridge, no crack and glue.

Wear resistance is an indicator of whether the sole is easy to wear. It is one of the important quality indicators of footwear. The wearing resistance of the outsole is not qualified, which will cause the shoe to wear out because of the serious wear or abrasion of the sole, which greatly reduces the service life of the shoe.

The reasons for the failure of the project are: first, the unreasonable formulation and low glue content; two, the manufacturer has to save the cost, and the sole pattern is too deep while the sole thickness is too thin in the sole forming process.
