Applications:
The rigid fiber wadding produced by this line is primarily used for:
New-style chemical fiber and coir fiber mattresses (made from coir fiber and polyester staple fiber; free from glue, formaldehyde, and other harmful substances; non-toxic, odorless, fire-resistant, and compliant with European environmental standards). Suitable for high-end mattresses, sofa cushions, etc.
Chemical fiber rigid wadding (an alternative to foam, made from polyester staple fiber; non-toxic, odorless, fire-resistant, and compliant with European environmental standards). Suitable for high-end mattresses, sofa cushions, filtration materials, sound-absorbing felt, etc.
Hundreds of these production lines are currently in operation. Companies such as Zongbao Coir Fiber Co., Ltd., Kunshan Jimeichuan Fiber Technology Co., Ltd., Guangdong Boluo Derkang, Guangdong Nanhai Jiujiang Yuandong Foam Factory, and Jiangsu Suzhou Mowei Natural Fiber Materials Co., Ltd. all utilize multiple units.
Main Specifications:
Product width: 2700–4500 mm

Production capacity: 30–35 tons/day
Heat consumption: 200,000–400,000 kcal
Product weight: 100–6000 g/m²
Product thickness: 10–200 mm
Line speed: 2–12 m/min
Structural Features:
① The oven utilizes dual Teflon mesh belts; the upper air plenum rises and falls in synchronization with the mesh belt.
② Features pressurized penetration heating with alternating airflow (top-down/bottom-up and bottom-up/top-down).
③ Air pressure is regulated via variable frequency drives (VFD); hot air circulates via convection.
④ High thermal efficiency ensures uniform heating and stable product properties (thickness, hardness, and shape retention).
⑤ Cutting is performed using a moving platform system; the platform synchronizes with the oven's line speed during the cut to maintain constant speed, achieving a cutting precision of ±1 mm.
⑥ Oven parameters—including temperature, speed, air pressure, product thickness, and cutting length—are fully controlled via an automated HMI (Human-Machine Interface) system.
Production Process Flow:
Hot drying oven → Cold-press setting machine → Cooling and setting oven → Roller → Longitudinal slitting → Roller → Flying knife cutting (moving platform type).
