Micro elastic safety braid

Abstract

The invention discloses a micro elastic safety braid which is formed by blending an elastic material and tensile high-intensity yarns, wherein the elastic material is formed by polyester drawn textured yarns or polyamide low stretch yarns; the tensile high-intensity yarns are formed by polyester high-intensity yarns and polyamide high-intensity yarns; the mass percentage of the elastic material in the micro elastic safety braid is 15 percent to 20 percent; the mass percentage of the tensile high-intensity yarns in the micro elastic safety braid is 80 percent to 85 percent; and the micro elastic safety braid has a width of 4cm to 6cm and a thickness of 1mm to 2mm. By the mode, the micro elastic safety braid mainly faces the market of an automobile safety belt and a working aloft safety belt; under the emergency condition, the micro elastic safety braid rapidly takes a protection effect, but can be used for preventing secondary damage due to a certain buffer elasticity; and due to a certain elasticity, the micro elastic safety braid is more comfortable to wear at ordinary times and has no constraint feeling with a high pressure.

Description

technical field [0001] The invention relates to the field of safety belt materials, in particular to a microelastic safety webbing. Background technique [0002] With the rapid development of science and technology, seat belts are used more and more widely, including working at heights, cars, bungee jumping, rock climbing and so on. Especially as a car seat belt, since its launch, more than 1 billion cars have installed seat belts. As a precautionary measure for emergencies, seat belts provide the final guarantee for life, so its quality is the first The main purpose is to meet a certain tensile strength and aging resistance, and to give a certain pre-tightening force during normal work, so that the seat belt will be tightened immediately in case of an emergency, and the body is firmly bound on the seat. Prevent your face from hitting the airbag or glass. However, car seat belt injury incidents occur frequently. Because the seat belt is tightened too fast, it suddenly...

Problems solved by technology

However, car seat belt injury incidents occur frequently. Because the seat belt is tightened too fast, it suddenly strangles the user's body like an iron rod. The huge inertia of the body often leads to strangulation of the epidermis and even internal organs.
