Once the pack belt force exceeds a certain limit, it will be appropriate to relax force limiters seat belt, keeping the chest by the stabilizing force. Therefore, the car seat belt restraint displacement and plays the role of a buffer to absorb the impact energy, resolve inertial force, avoid or reduce the extent of injuries of the occupants. Car accident surveys show that in event of a frontal crash, if wearing a seat belt, can reduce the mortality rate of 57%, can be reduced 44% during the side crash can be reduced to 80% when overturned.

In recent years, with economic development and people's living standards improve, automotive interior luxury and comfort in the direction toward the development of automobile seat belts Safety Products is also the interior decoration textiles, it must have regard elegant in appearance, comfort freedom Features. So it need to have the following special properties:

(1) fabric soft, comfortable touch.
(2) Gloss coordination, especially in the performance of its anti-surface effect
Optical tape must be clear and full, in order to increase their sense of luxury.
(3) both durable fabric, but also lightweight.
(4) to have other properties of flame retardant fabric, heat and so on.
In summary, the car seat belts total technical requirements; safe, comfortable and beautiful.

After several tests proved polypropylene filament have high strength, excellent wear resistance, acid and alkali resistance, elastic recovery rate of 96% to 100%, lightweight and inexpensive, etc., it is the ideal raw material for the production of automobile seat belts.
