Material and manufacturing process of car seat ventilation net bag

I. Materials

1. Airtight Non-Woven Fabric:
   The car seat ventilation mesh bag primarily uses two layers of airtight non-woven fabric as the main material. This material offers excellent airtightness and breathability, effectively preventing gas leakage while ensuring ventilation performance.

2. PU Edge Binding:
   The edges of the ventilation mesh bag are often treated with PU (polyurethane) material for binding. PU boasts superior wear resistance and weather resistance, significantly extending the product’s lifespan.

3. 3D Spacer Fabric:
   Inside the ventilation bag, 3D spacer fabric is integrated, featuring irregular air channels. This design allows air to flow sequentially through the intake port, air channels, and finally exit via ventilation holes, enabling effective seat ventilation.

II. Manufacturing Process

1. Material Preparation:
   Prepare raw materials such as airtight non-woven fabric, PU material, and 3D spacer fabric.

2. Cutting and Heat Sealing:
   Cut the airtight non-woven fabric to the required dimensions based on design specifications. Use heat-sealing equipment to weld the edges, forming the basic structure of the ventilation bag.

3. Intake Port Creation:
   Create intake ports on the sealed edges of the ventilation bag to allow airflow into the mesh structure.

4. 3D Spacer Fabric Installation:
   Position and secure the 3D spacer fabric inside the ventilation bag to ensure unobstructed air channels.

5. PU Edge Binding:
   Apply PU material to bind the edges of the ventilation mesh bag, enhancing durability and aesthetics.

6. Quality Inspection:
   Conduct post-production quality checks, including airtightness testing, ventilation performance evaluation, and other assessments to ensure compliance with design standards and quality requirements.

Summary
The materials and manufacturing processes of car seat ventilation mesh bags reflect a commitment to comfort and durability. By utilizing high-quality materials like airtight non-woven fabric, PU, and 3D spacer fabric—combined with meticulous craftsmanship—the product achieves optimal ventilation functionality while maintaining superior quality and performance.
