With the improvement of our national living standard, the car has become one of the main means of transportation, followed by people's concerns about the safety performance of the car. Automobile safety is divided into two types: active safety and passive safety. Passive safety is the ability of the car to protect the human body in the event of an accident, including the performance of the seat belt
The production process of Qidong safety belt is completed through multiple processes. The following is a brief description of the production process of automotive seat belts
First of all, the production of car seat belts begins with the preparation of raw materials. The main raw materials of the safety belt are poly red and nylon red, of which poly red can provide strength and toughness, while nylon fiber can provide wear resistance and high temperature resistance. These raw materials need to be combed, cleaned, dried, etc., to ensure the quality of raw materials.
Second, raw materials are fed into textile machines for spinning. In the textile process, raw materials are stretched and woven to form the fibrous structure of the harness. At the same time, according to the needs of the product, different weaving methods can be used, such as plain, twill, satin, etc., to increase the strength and comfort of the safety belt. After the textile is completed, the fabric of the belt is sent to the dyeing workshop for dyeing. The dyeing process can make the seat belt have a rich color to meet the market demand, and the dyeing agent can improve the light resistance, wash resistance and wear resistance of the fiber
The dyed fabric is then sent to the cutting shop for cutting. In the cutting workshop, according to the design requirements, the temperature of the fiber fabric is adjusted, and then the mold is cut according to the size requirements. The cut fabric is sent to the sewing workshop where, after a precise sewing process, the cut fabric is stitched to form the basic structure of the seat belt. In this process, attention needs to be paid to the selection of stitches and the strength of stitches to ensure the fastness and service life of the safety belt.
Finally, the safety belt will be inspected by multiple workstations, including tensile test, breaking strength test, wear resistance test, etc., to ensure that the quality of the safety belt meets the requirements of the relevant standards. Through these tests, the safety and reliability of the safety belt during use can be guaranteed.
To sum up, the production process of automobile seat belts includes raw material preparation, textile, dyeing, cutting, sewing and quality inspection. Each link requires rigorous operation and precise control to ensure the quality and performance of the seat belt, thus ensuring the safety of the driver and passenger.
