In high-speed, wide-width paper machine operations, improper selection or poor-quality dryer fabrics directly lead to visible losses:
Persistently high energy consumption: Mismatched permeability design with actual machine conditions prevents effective steam heat penetration, reducing drying efficiency and driving up steam costs per ton of paper.
Frequent paper defects and rising reject rates: Uneven fabric surface causes wire marks and impressions; contaminant buildup creates cross-directional moisture non-uniformity and wet streaks, severely affecting finished product quality and rewinding operations.
Frequent sheet breaks and costly downtime: Edge flutter, sheet floating, and cylinder sticking in the drying section result in extremely high downtime and broke costs.
Short fabric life and frequent replacement cycles: Issues such as uneven guide roll surfaces, cylinder temperatures exceeding 120°C, and insufficient cleaning water pressure (below 50 MPa) accelerate fabric wear, hydrolysis, and yarn shedding, significantly shortening service life.
In response to the challenges above, Hengyuan's products and services deliver clear value commitments:
1. Precise Selection to Target Energy Consumption
Different paper grades and machine speeds require entirely different permeability specifications. We provide machine-condition-based custom grouping solutions:
For high-permeability zones (e.g., first dryer group) in typical domestic paper machines: fabric permeability of 90-100 cfm with MD tensile strength ≥ 1900 daN/10cm
For mid-to-late drying zones (groups 2-9): permeability increased to 110-150 cfm
Only when the permeability precisely matches the machine's drying curve can optimal utilization of steam heat energy be achieved.
2. Anti-Contamination Design for Extended Life and Reduced Downtime
Drawing on industry best practices, advanced dryer fabrics with optimized weave structures reduce contact area and prevent stickies accumulation, extending service life by over 20%. Hengyuan employs optimized weft weave patterns and hydrolysis-resistant material technology, effectively delaying high-temperature aging and embrittlement to extend fabric life from the industry average of 2-3 months to over 20 months.
3. Smooth Surface to Eliminate Paper Defects
Flat monofilament (profile) dryer fabrics are the preferred solution for high-smoothness paper grades. Through specific weave patterns (such as 4-shaft satin) using 0.52mm × 0.335mm flat warp monofilaments combined with fine and coarse wefts, we achieve a smooth surface while maintaining high support points, effectively eliminating wire marks and impressions.
Breaking monopolies: We are one of the few domestic manufacturers capable of producing low-permeability (below 75 CFM) flat monofilament dryer fabrics – a technology long monopolized by foreign suppliers.
State-of-the-art equipment: Equipped with German Jürgens wide-width looms, German Jäger heat-setting units, and Austrian WIS fully automatic seaming machines, with key processes digitally controlled to ensure batch-to-batch consistency and scalable, repeatable production.
Proven track record: Our products are widely applied in domestic paper machines operating at speeds of 1,500 m/min and above, with a documented industry record of 20-month service life.
Industry data demonstrates that the large-scale supply of domestic dryer fabrics helped drive down international market prices for comparable packaging paper dryer fabrics from over RMB 1,000 per square meter to the several-hundred-yuan range. This is not simple price competition – it is the value return brought by technological independence.
Choosing Hengyuan means you receive not just a fabric, but a comprehensive "Fabric + Selection Service + Life Commitment" solution. We promise: through data-driven selection and on-site service, we will deliver verifiable improvements in steam energy consumption, machine speed, and sheet break reduction – the three core metrics that drive your profitability.
