Cut-resistant gloves are generally divided into two types, one is used for industrial production protection, commonly used in food engineering, biological engineering, electronics industry, mechanical protection, glass industry, etc.; the other is the police type protective gloves, used for disaster relief and rescue, fire rescue, etc.
Cut-resistant gloves commonly used in three kinds of materials
1, aramid (Kevlar): aramid is an aromatic polyamide products, the original color of the fiber is yellow, strong and light, flexible, 5 times stronger than the same weight of steel, flame resistant, will not melt at high temperatures. Therefore, more suitable for high-temperature work workers, such as: metal smelting, industrial welding, glass processing, etc.
2, high strength polyethylene fiber (Dyneema): tough and lightweight, good fit, good wear resistance, small coefficient of friction, high strength, more than ten times the same cross-section of steel wire. Mostly used for high-strength industry workers, such as: metal processing, body assembly, stamping operations, etc.
3, steel wire and polyester fiber weave: steel wire gloves cut resistance is the highest, suitable for coping with the knife edge of human operations, in addition to applications in the food processing industry, but also for defense against animal bites.
We can see from the material of the cut-resistant gloves, can only cope with the knife blade of human operation, if it is a high-intensity cutting is not necessarily. The specific can be determined according to the cut resistance test.
To perform the cut resistance test, a sample is taken from the palm of the glove, and a tungsten steel rotary cutter is used to cross-cut back and forth, and the number of revolutions required to cut through the sample is recorded to compare the results of a standard cotton sample that is staggered and tested at the same time, and the higher the index calculated, the stronger the cut resistance. However, the cut resistance test is not applicable to very hard materials.
High-strength polyethylene fibers are cut resistant up to level 5, while aramid is level 4 to 5. Generally speaking, man-made fibers are better than natural, cotton is better than leather, and leather is stronger than latex.
