Cut-resistant-fabric:How to identify the cut-proof gloves currently on the market

There are many kinds of cut-proof gloves, which are managed by a standard test system. Generally, the current market is one Cut-resistant-fabric of the European standards for the safety prevention of industrial production gloves EN388, which was approved by the European Normative Institute (CEN) on July 2, 2003 according to the latest version of EN388:2003. This standard provides standard specifications, test methods, signage and manual for safety prevention of reflection damage of labor protective gloves in most parts of the glove practical standard EN420.Cut-resistant-fabric


The four basic test properties of this standard are:


Wear resistance gloves raw material resistance to continuous friction coil turns;Cut-resistant-fabric

The number of times the raw material of the cutting resistant gloves is resistant to fiber laser cutting objects;


Resilience that is to tear open the hole in the glove raw material must be how much money the company force;


Puncture resistance is the force required to Pierce the palm of the glove with a corrected spike.


A. Wear resistance test: Four circular glove raw material samples (6.45 cm²) are rubbed under A known pressure (9 kPa), and each sample is tested for 100, 500, 2000 and 8000 turns respectively. The performance grade is determined according to the number of turns of the coil after four tests. For example, if raw material A is tested, if it is damaged after being rubbed 500 times, the wear resistance level of this raw material A is level 1, and so on;


B. Cut resistance test: the two samples were tested under the sustained force of 5 Copernicus specification, and the grade was established according to the number of coil turns borne before cutting;


C. Resilience test: Four samples were cut from the palms of four gloves. Two of them were tested in the direction of finger to sleeve, and the other two were tested in the direction of palm width to accurately measure the strength of tearing samples at a speed of 100 mm/min.


D. Puncture resistance test: As for arylon fiber 1414 fabric, four samples cut from the palms of four gloves were used to accurately measure the large Copernican force of steel nails piercing the samples at a speed of 100 mm/min.


Cut-proof gloves are generally divided into two kinds. One is used for safety prevention in industrial production, which is more common in food engineering, biotechnology, electronic industry, industrial equipment safety prevention, industrial production of toughened glass, etc. The other is police equipment type safety gloves, used for earthquake relief and rescue, fire rescue and so on.


Cut-proof gloves are commonly used as three raw materials


1, aramid fiber (Kevlar) : aramid fiber is a lipid ring acrylic emulsion products, synthetic fiber primary color is light yellow, strong and light weight, flexibility, relative to sexual intercourse in the net weight of steel 5 times stronger, flame retardant, not easy to melt at high temperature. Therefore, it is more suitable for field workers, such as: industry, industrial production arc laser welding, glass deep processing and so on.


2, high toughness polyethylene fiber (Di Malegobi) : fortitude, light weight, good compliance, good wear resistance, small friction, high wear resistance, is the same section of stainless steel wire more than ten times. It is mainly used for high wear-resistant production and manufacturing field workers, such as: optical fiber laser cutting production and processing of metal materials, body installation, hardware mold operation process and so on.


3, stainless steel wire and polyester fiber fabric cloth hand knitting: stainless steel wire gloves have large professional ability to prevent cutting, suitable for solving the knife edge of human resource management operation process, in addition to the application in the field of food production and manufacturing, but also used for defense ability of animal biting.


As can be seen from the raw material of the cut-proof gloves, only the cutting edge of the human resource management operation process is solved, if it is a high-wear fiber laser cutting is not necessarily.


For the anti-cut test, the sample was taken in the palm of the glove, and the fiber laser was cut back and forth with a rotating cutter of tungsten steel material, and the speed ratio necessary to cut through the sample was recorded to compare the results of the standard cotton fabric samples for overlapping verification test. The higher the calculated index, the stronger the anti-cut performance was. However, the cut resistance test does not apply to very hard materials.


High toughness polyethylene fiber cut to achieve 5 levels, aramid fiber is 4 to 5 levels. In general, man-made fibers are better than natural, all collodion leather products are better, leather products are stronger than natural latex mattresses.
