How To Check The Safety Shoes Quality
At present, the safety shoes on the market are mainly cowhide, and synthetic leather is very rare; a good pair of safety shoes mainly depends on two parts; one is to see the quality of the safety upper leather, this average person can’t distinguish, cowhide. Dowell is a professional safety shoes, PVC boot, EVA boots, manufacturer in China. If you want to wholesale the safety boots, please contact us.
The four ways to distinguish are;
One: Look The Safety Shoes
The top layer of cowhide has uneven distribution of lines, because in the process of “smashing the skin”, the lines will follow the natural lines of the cowhide, so there will be patchy lines, and the 2 layers The above cowhide or leather will not have such scattered lines
Two: Pinch The Safety Shoes
Just a light press, the cowhide will show good elasticity, after pressing it down, it will quickly return to its original shape, and you will see irregular natural patterns when you remove it.
Three: Smell The Shoes
The imported first layer of cowhide smells of cattle, people who are not used to it smell and feel a kind of light smell, in fact, this is not a real smell, but everyone’s sense of smell is different, for a long time Now, you will find that it is the “fresh fragrance” of real leather. Fake leather or leather smells pungent like plastic.
Four: Burning The Safety Shoes
When burning with fire, the dermis will not form hard lumps and has the smell of burning hair, while the fake leather will form lumps and give off an irritating smell when burned.
The cowhide in the market is mainly the two-layer cowhide of cowhide. One layer of cowhide is more expensive and only used for high-end products. Only a few of the safety shoes (labor protection shoes) iin use;
Another part is the sole of safety shoes (labor protection shoes). The soles of safety shoes (labor protection shoes) on the market are mainly made of two materials, one is made of rubber, and rubber is divided into natural rubber and synthetic rubber according to the raw material. Highly elastic polymer material with reversible deformation.
It is elastic at room temperature, can produce greater deformation under a small external force, and can return to its original state after the external force is removed. The rubber has the characteristics of oil resistance, acid and alkali resistance, and high temperature resistance; the disadvantage of rubber is that it is relatively heavy;
There is also a kind of material that is, PU injection bottom, injection molding is machine-made shoes. After the upper is tied on the aluminum last, it is usually directly injected into PVC, TPR and other materials by the turntable machine to form the sole at one time. Now there are also PU (chemical Name polyurethane) injection molding (the machine and mold are different from general injection molding).
Advantages: Because it is machine-made, the output is large, so the price is low. Disadvantages: If there are many styles, it is more troublesome to change molds, it is difficult to shape the shoes, and the workmanship of cold glue shoes is not exquisite, so it is generally suitable for orders with a single sole style;
Be sure to pay attention to the following points when choosing safety shoes and protective shoes;
1. Check the upper and the materials in the shoes. High-quality safety shoes (labor protection shoes) have fine and shiny leather, no color difference in the main parts, no disability, no loose skin on the back of the finger, no peeling off and no cracking of the coating layer, and the inner material of the shoes should also be natural leather.
2. Check the soles. Use your fingernails to press the soles lightly. Good-quality soles are elastic, soft and hard, and do not peel off.
Three, check the heel. The shoes can be placed flat on the counter. Good quality shoes should be stable. The palm surface of the heel should be in contact with the countertop, and the heel of the same pair of shoes should be the same height.
Fourth, check the shank. The shank is a key part that is installed between the outsole and the inner midsole of the leather shoe to support and shape the shape. Place the shoe flat on a solid table and press the shank hard. The qualified shoe should not be soft or deformed.
5. Check the main heel and Baotou. The main heel is the key component of the rear upper and is installed between the upper of the heel and the shoe inner; the toe cap is the component of the toe, and it is installed between the front upper and the upper. Fingers can be used to press (lift) the main heel and toe cap during inspection, and high-quality shoes should be able to withstand pressing.
Reach into the shoe to check whether the installation position is correct. If it can directly touch the main heel and toe cap materials, it means that the process is unreasonable.
