Cut Resistant Fabric And Puncture Resistant Fabric

- Jun 18, 2020-

The use of personal protective equipment has actually taken shape in ancient times. At that time, the soldiers were wearing a thick metal or leather armor, but such armor is extremely restricted due to the weight. Daily activities. Now, after the "9.11" incident, the world has been preparing for a long-term anti-terrorism war, which has made personal protective equipment a major issue worldwide. How can better protect personal safety? This requires a large amount of personal protective armor materials such as bulletproof vests, helmets, cut-proof gloves, stab-proof cut-proof cloth, etc. In the use of guns and ammunition, some countries have strictly controlled , The rest is how to protect the human body from bayonet dagger sharp weapon damage this urgent need to solve the problem.

 

 Cut Resistant Fabric and Puncture Resistant Fabric

The damage caused by knives and daggers can be divided into two types, cut-proof and stab-proof. During the puncture process, the knife will come into contact with the stab-proof and cut-proof cloth and start to cut the fabric, so the material requirements for the stab-proof and cut-proof cloth must have a tight organization, which can hold the blade tip, and also need multiple layers of fabric Overlapping to resist the energy accompanying the blade tip, the task of stab resistance is to defend the initial cutting and scattered energy of the knife. The anti-cutting performance is the basis of the anti-cutting performance, but having the anti-cutting performance does not guarantee good anti-puncture performance. It also requires a certain degree of material tightness. In general, anti-puncture is more difficult than anti-cut. According to previous data, the anti-stab mechanism is mainly a friction self-locking mechanism. With the deepening of the thorns, the yarn will pull out and slip, and the expansion of the yarn will make the adjacent yarn pull out and tighten. The force required for yarn drawing is the sum of the frictional forces on the drawn thread during the drawing process. During the piercing process, when the pierced yarn reaches a point where it cannot continue to expand, the blade will stop deepening. The frictional force of the yarn required for expansion is of an order of magnitude. As long as the coil wire can continue to slide, the blade will continue to penetrate deeper. If the strength of the yarn is strong enough, when the coil wire reaches the level of slippage, the fabric deformation reaches The state is called "locked" state. This state is achieved because the adjacent thread is tightened due to the slippage of the yarn during the penetration of the thorn, and the number of tightened yarns follows the slippage of the yarn.

 Cut Resistant Fabric and Puncture Resistant Fabric

 

It can be known that the main damage mechanism of the stab and cut-proof cloth is the compression shear of the cutter along the cross-section along the object and the tensile fracture of the yarn in the axial direction, so the yarn material in the stab-resistant material needs to have a higher shear resistance Ability and high tensile strength. In addition, puncturing knives generally have sharper tips. Therefore, in order to prevent the tip from penetrating the fabric, the puncture resistant fabric needs to have sufficient tightness.
