AQSIQ: The Quality Of Leather Shoes Is 98.2%.

AQSIQ recently organized a national supervision and spot check on the quality of leather shoes.

A total of 90 products produced by 90 enterprises in 8 provinces and municipalities in Zhejiang, Fujian, Guangdong, Sichuan, Shandong, Chongqing, Jiangsu, Shanghai and other provinces (including no export products) were surveyed, and the qualified rate of physical samples was 98.2%.

Among them, 7 kinds of national inspection free products and 2 kinds of Chinese famous brand products were selected. The qualified rate of physical samples was 100%.

Interpretation of the report: two indicators are easy to be "out of shape". According to the requirements of the QB/T1002-2005 "leather shoes" standard, the spot checks on the sensory quality of the leather shoes, the peel strength of the bottom, the strength of the upper shoe, the folding resistance of the shoe, the wear resistance of the shoe, the heel binding force, the hardness of the sole, the hardness of the bottom, the rigidity of the hook, and the marking of the logo are tested in the 10 items.

The results of spot checks show that the state supervision and spot check has promoted the improvement of the quality consciousness of enterprises and strengthened the quality management. The product's hook bending stiffness, wear resistance at the bottom, the heel binding force, the strength of the upper shoe and the hardness of the sole shoe heel meet the single coincidence rate of 100%.

In addition, the large scale production enterprises with higher market share have better product quality, and all the inspection items meet the requirements of the national standard.

Although the overall quality level is relatively high, it is still found in some spot checks that the flexural strength and peel strength of individual products are not up to standard. It is easy to produce deformation and fracture during the wearing process, which will affect the service life of the products.

It is understood that the folding resistance is the index to assess whether the shoe sole and the side of the shoe are easy to break or crack, which directly reflects the flexural flexibility of the outer sole of the leather shoes, and is the comprehensive quality index of the wearing life of leather shoes.

QB/T1002-2005 "leather shoes" standard stipulates that the folding resistance of leather shoes should be less than 30mm, and the new cracks should be less than 5.0mm after folding, and should not exceed 3.

In the spot checks, there are individual products with fracture resistance length of 72.6mm, exceeding the requirements stipulated in the standard limit value.

In addition, peel strength is an important index for evaluating the adhesive strength of leather shoes and the sole. The products with low bonding strength may produce glue during the wearing and storing process, thus affecting the appearance and quality of the shoes.

QB/T1002-2005 "leather shoes" stipulates that the peel strength of leather shoes is not less than 40N/cm.

In the spot checks, the peel strength of individual products is 24N/cm, which does not meet the requirements of the standard minimum value.

Expert advice: "face" and "inside" both inside and outside the relevant experts remind consumers, material quality is the key factor affecting the quality of leather shoes.

The main types of leather materials are cowhide, pig skin, sheepskin and other natural leather. The hardness, wear resistance and luster of different materials are different.

To judge the quality of leather shoes leather, press the fingers to press the leather shoes first. If there are big wrinkles, it means that the cortex is not good, there are radioactive fine lines. After the fingers are released, the fine lines disappear, indicating that the elasticity is good and the leather is good. Besides, the surface of the products should be smooth and meticulous, bright and bright, and the overall color is uniform. The coating layer is firm, not loose and not cracked.

Those who meet the above characteristics are of high quality.

As for the popular lacquer shoes this year, they are also very particular when choosing.

Lacquer shoes are usually divided into two kinds: one is made of synthetic leather after spraying chemical raw materials, the other is a bright, pparent bright paint on the dyed leather.

The former is usually heavy in color and relatively thick in the cortex, but its texture is hard and its air permeability is slightly worse.

The latter is usually made of natural cortex, and the pparent paint only sprayed a thin layer on the outside of the shoe, which does not limit the extension of the shoe's cortex itself, so the texture is relatively soft, and it is comfortable to wear. The disadvantage is that it is easy to wear wrinkles like ordinary leather shoes.

In addition to the bright "face" problem, consumers should pay more attention to the quality of shoes.

It directly affects the comfort of a pair of shoes.

For example, many fashionable leather shoes are very bright on the surface, but the synthetic leather material with poor quality is used in the shoes, and the hardness of the paint itself is very uncomfortable.

In order to avoid buying similar shoes, consumers can distinguish the quality of "Li Zi" by color, texture and softness.

Generally speaking, the fibers in the real leather layer are naturally distributed from the inside to the outside from the tight, loose surface, while the inner layer of synthetic leather and synthetic leather is artificially made of knitted or textile base, and there is no natural distribution of density.
