AI Technical Summary

Technical Problem

Existing composite fabrics have problems during the manufacturing process, such as uneven glue application, glue overflow after pressing single-layer fabrics together, and moisture penetration at the seams of composite fabrics, which affect the cooling sensation and antibacterial properties of clothing.

Method used

The cooling antibacterial composite nano protective fabric spraying device uses an expansion roller to open the fiber fabric strip and spray it with a cooling finishing agent. Combined with a drying oven and a cutting and bonding device, it achieves uniform impregnation of the cooling finishing agent and sealing of the adhesive film, avoiding excess adhesive and moisture penetration.

Benefits of technology

It improves the washability of the cooling finishing agent and the cooling properties of the garment, increases the comfort of wearing in high-temperature outdoor conditions, and ensures the sealing of fabric seams to prevent moisture penetration.
