Definition and Function
Definition: An automotive ventilation bag is a bag structure used in car seat back ventilation systems. It achieves breathability through specific design and material selection.
Function: The primary function of the automotive ventilation bag is to allow air circulation within the seat, dissipating heat and moisture generated by the passenger’s body, thereby providing a more comfortable riding environment.
Materials and Structure
Materials: The automotive ventilation bag is primarily composed of TPU transparent film, 3D spacer fabric, and non-woven fabric. The TPU film offers excellent breathability and wear resistance, the 3D spacer fabric enhances structural strength and airflow, while the non-woven fabric provides comfort and filtration.
Structure: The ventilation bag is manufactured using high-frequency processing, featuring a three-layer structure: one layer of TPU film, one layer of mesh fabric, and another layer of TPU film. This design ensures breathability while maintaining durability and strength.
Production Process
High-Frequency Welding: During production, materials are arranged sequentially on the workstation of a high-frequency welding machine. The edges of the ventilation bag are sealed via high-frequency welding, and excess material is trimmed. This method ensures robust and aesthetically pleasing seams, guaranteeing airtightness and longevity.
Equipment Types: High-frequency welding machines for automotive seat ventilation bags come in various configurations, such as left-right sliding table models, automatic turntable models, and fully automated production lines, catering to diverse production scales and requirements.
