Product Details
Production Line Overview
Non-woven Fiberfill is an environmentally friendly filling material widely used in home textiles, apparel, automotive interiors, medical protection, and other fields. This production line employs advanced technologies for fiber opening, carding, web formation, and hot-air thermal setting, enabling automated, high‑efficiency manufacturing of non‑woven cotton. The resulting product boasts excellent loft, uniformity, and the absence of chemical binders, meeting stringent environmental and health standards.

Core Process Flow
Raw Material Preprocessing

Fiber opening: Raw materials such as polyester, PP cotton, and ES fibers are loosened by an opening machine to remove impurities, resulting in loose, dispersed fibers.

Blend formulation (optional): Adjust the proportions of different fibers as needed to optimize product performance, such as softness and elasticity.

Fiber Carding and Web Formation

High-speed carding machine: It cards the opened fibers into a uniform, single-layer web, ensuring no neps and consistent thickness.

Cross-lapping: A web-forming machine is used to stack multiple layers of fiber webs, with basis weight (typically 50–300 g/m²) and loftiness adjusted.

Hot-air setting

Hot-air oven: Uses hot air (120–180°C) to melt and bond low-melting-point fibers (such as ES fibers), enabling shaping without the use of adhesives while preserving a fluffy structure.

Cooling and shaping: The material is calendered through cooling rollers to stabilize its thickness and strength.

Finishing and Slitting

Calendering (optional): Enhances surface smoothness through hot-rolling rollers, suitable for applications such as garment interlinings.

Automatic cutting: Cut into rolls or sheets according to customer requirements, with an accuracy of up to ±1 mm.

Production Line Advantages
✅ Eco-friendly, glue-free: Utilizes hot-melt bonding technology, free of formaldehyde and VOCs, and compliant with international standards such as OEKO-TEX®.
✅High loft: The fiber’s three-dimensional structure is stable, and its resilience surpasses that of conventional spray-bonded cotton.
✅ Flexible customization: We can produce glue-free cotton with varying basis weights (50–500 g/m²), thicknesses (5–50 mm), and levels of softness or firmness.
✅ High degree of automation: The PLC control system enables precise temperature control and speed adjustment, minimizing manual intervention.
