Quality Identification of Safety Shoes
Identification of vamp materials
At present, the common materials for the upper safety shoes on the market are suede leather, film transfer leather, broken cow leather, cow leather, etc. As the appearance of film transfer leather is very similar to that of cow leather, many consumers cannot judge. Now we compare and analyze the two materials.
First look: cow leather (the kind of leather, which is a common name for people to distinguish synthetic leather in the leather products industry) has obvious irregular patterns and natural pores on the surface, which is cold-resistant, folding resistant, breathable, and sweat-wicking; Film transfer leather, collectively referred to as natural synthetic leather, is an artificial surface layer pasted on the loose meat surface fiber layer under the natural leather. Its grain pattern is similar to that of natural leather, but it has no pores and a hard feel, but it has good waterproof performance.
Second touch: feel plump, elastic, and sexy. The leather without a cold feeling is leather, and the leather with a hard and cool feeling is mostly film transfer leather. III. observation from the cross-section: there is no obvious film layer in the cross-section of the dermis. If you scratch the bottom base by hand, you will find fluff, and grow longer and longer, which is the most obvious manifestation of the fiber base (dermis base); Film transfer leather is made by grinding the loose meat surface fiber layer or fiber on the lower layer of natural leather, bonding it with adhesive under high pressure to form a sheet, then pasting it with an artificial surface layer, scraping the surface layer with a knife-edge, and some surface layers can peel off in small pieces.
The production process of safety shoes is divided into molding, injection, gluing, and sewing. Injection safety shoes are light, with high viscosity between sole and upper. The outsole is usually made of polyurethane, which is wear-resistant and waterproof; Adhesive shoes are a traditional process with a long history of production. Generally, the soles are made of rubber and other materials, and the shoes are bonded with glue and uppers; The price of sewing tire soles and molding technology is relatively cheap. They are low-grade products, so we won't introduce them here.
Materials of safety shoes
Toe protection safety shoes need steel toe cap, anti-puncture safety shoes need steel soleplate, anti-static shoes need an anti-static agent and anti-static wire, etc. observe and it is necessary to carry out protective performance test to find out whether it meets the certified product grade of the supplier and whether the quality of shoe materials and accessories meets the requirements.
