Nonwoven Calendering Machine

Nonwoven Thermal Calendering Machine is a high-precision bonding system engineered for thermal consolidation of spunbond, spunlace, ES fiber, geotextile, and biodegradable fiber nonwovens. The equipment operates through coordinated heat and pressure application to achieve fiber-to-fiber bonding without chemical adhesives. Available configurations include two-roll standard type, Y-type three-roll uniform type, high-speed wide-width type, and custom ultra-wide models with maximum working width up to 7000mm, top speed 800m/min, and line pressure capacity 150N/mm. The complete system integrates self-developed matched roller assemblies, closed-loop process control, and a stress-relieved heavy-gauge frame structure supporting continuous 24/7 operation across hygiene, medical, geotextile, automotive, and filtration material production.

Product Advantages
Integrated Roller System & Industry Standard Leadership – The company is the lead drafter of the industry standard for nonwoven thermal calendering machines, combining in-house roller manufacturing with complete machine design capability. The thermal bonding rollers incorporate a patented surrounding deep-hole heat exchange channel structure enabling full-surface thermal uniformity. Paired with a closed-loop temperature control module, the system maintains full-width temperature differential ≤±0.65℃ and fabric basis weight deviation within ±2.5g/㎡, increasing premium hygiene material yield rates by over 18%.
Advanced Pressure Control – A servo-hydraulic pressure mechanism with 0–30mm axial cross-axis adjustment compensates for roller deflection under load in real time. Line pressure is infinitely adjustable up to 150N/mm, maintaining constant nip pressure across the entire web width. This eliminates edge tightness, loose edges, and wave wrinkles at speeds up to 800m/min, ensuring consistent bonding strength for both lightweight and heavyweight nonwovens.
Comprehensive Model Range & Ultra-Wide Customization – Standard configurations cover two-roll, Y-type three-roll uniform, and high-speed wide-width models serving both small-scale production and large-scale industrial lines. Standard working widths are 3600mm and 5400mm, with custom designs up to 7000mm available—one of the few domestic manufacturers capable of delivering ultra-wide thermal bonding equipment.
Heavy-Duty Frame & Dynamic Balancing – The main frame is constructed from thick steel plate with full stress-relief annealing to eliminate internal stress from welding. Each roller undergoes three-stage dynamic balancing calibration under simulated load to G0.8 grade, ensuring no frame deformation or vibration under 24/7 full-load operation.
PLC Closed-Loop Control – The proprietary HMI control system integrates temperature, line pressure, and speed parameters in a coordinated loop. Up to 100 process recipes can be stored and recalled for different materials and basis weights, enabling quick changeovers. The system supports remote monitoring and data traceability for EU medical device and automotive interior material production requirements.

Application Scenarios
Medical and hygiene nonwovens (SMS, spunlace, thermal bond cotton for diaper topsheets, medical bed sheets, mask layers, feminine care products) with consistent softness, tensile strength, and skin-contact safety for Southeast Asian and European hygiene product manufacturers. Geotextiles and industrial filtration felts (polyester needle-punched geotextiles, dust filter fabrics for infrastructure and industrial emission control) with enhanced density and tear strength for Middle Eastern and Latin American infrastructure projects. Automotive interior fiber substrates (roof liners, seat backrest materials) meeting European automotive interior standards for Turkish and Polish automotive parts suppliers. Biodegradable plant-fiber nonwovens (PLA, straw fiber eco-friendly materials) with low-temperature thermal bonding and REACH compliance for European markets. Home textile nonwovens and cleaning cloth substrates (wiping cloths, curtain liners) balancing bulk and durability for Japanese and Korean household brands. Paper and fiber composite board hot-pressing (thick cardstock, wood fiberboard) for packaging and lightweight building material applications.
