The press section of a paper machine is critical for determining sheet consistency before it enters the energy-intensive dryer section. Every 1% increase in sheet dryness leaving the press section translates to approximately a 4% reduction in steam consumption in the dryer group.
High-quality press felts engineered by Rajiv Machines utilize multi-layer base weaves combined with stratified batt fiber layers. This structure provides optimal capillary action and high void volume, allowing water expressed in the press nip to be evacuated rapidly without causing crushing or sheet re-wetting upon nip exit.
Key Engineering Characteristics of High-Performance Felts:
- Uniform Needling Density: Prevents premature fiber shedding and guarantees smooth paper sheet texture.
- Chemical & Thermal Resistance: High-grade polyamide batt withstands alkaline cleaning chemicals and high nip temperatures.
- Controlled Compaction: Maintains consistent thickness and hydraulic permeability throughout its operational lifespan.
