Large-volume rapier looms with crimping tension control system to make the base fabric more uniform, flat and small deformation.

The high-strength ultra-low shrinkage polyester fiber is processed through warping, double-twisting etc., and the weaved by advanced rapier loom and crimp tension control machine, which makes the base fabric more uniform, flat and small deformation , and more stable physical properties of the ventilation duct fabric, woven fabric and knitted fabric are available.

High-quality PVC membrane formula developed by our company is adjusted according to the difference of seasons, uses, service areas and performances, so as to ensure the stability of product quality, excellent cost performance, long service life and environmental adaptability.

Lamination is the perfect combination of base fabric and membrane. The oil temperature heating makes the temperature stable and controllable. The speed, tension and pressure are controlled by CNC, which effectively solves the quality problems such as delamination, bubbling and poor seam strength of the fabric. The Water-based antistatic surface treatment technology which is research and development with Sichuan University Jointly, implements none VOC emission during production and use, which will not cause harm to the environment and workers' health, and also stabilize the antistatic value at 3*106.

Self-developed ventilation duct automatic welding production line, constant temperature, speed and pressure, to ensure product consistency and stability.

Double hot air gun welding to improve the welding fastness.

Welding cooling system and traction system to make smooth welding seam.
