Double Warp Dryer Mesh
High Hydrolysis Resistant Double Warp Dryer Mesh is listed as a 4-harness double layer high-hydrolysis-resistance double-warp dryer mesh, in the Double Warp Dryer Mesh family. Its construction and the dimensional values below are transcribed from the supplied product schedule. The listed air-permeability window is (300-500 CFM) and is configurable for the machine position. The application notes identify high-temperature, high-humidity dryer sections serving cultural and packaging papers. Review the forming or dryer-section layout, furnish, seam and operating conditions before specifying.

Only values present in the supplied schedule are shown. Tolerances and final supply specifications require confirmation.
The supplied schedule lists high-temperature, high-humidity dryer sections serving cultural and packaging papers. For a dryer fabric, the position within a multi-cylinder dryer section matters because speed, contact conditions, sheet support and the desired air-flow window vary along the machine. For a forming fabric, the furnish, drainage demand, retention objectives and required sheet-side support should be reviewed together. The grade name alone is not enough to choose a construction.
Use the stated structure and yarn layout to shortlist the model, then compare it with the current fabric and the exact machine position. The available product information does not specify a guaranteed production result, service life or energy saving. Those outcomes depend on the operating system and must be assessed from the mill's own run data.
If this model is being considered as a replacement, share the paper grade, target basis weight, machine speed, fabric width, loop length, seam type and current permeability or forming data. The technical team can then verify whether the supplied schedule is appropriate or whether a position-specific variation should be discussed.
Air permeability should be selected for the machine position, not from a generic product label. Where the schedule lists a range, the final target is configurable and must be confirmed against operating conditions. Where no value is listed, request the value for the proposed construction rather than inferring it from another model.
For an actionable quotation, provide machine speed, paper grade and basis weight, fabric width, loop length, current fabric model or construction, current air-permeability or drainage data, seam arrangement and machine position. Include any observed operating issue only if you have measured or documented it. This helps distinguish a construction change from a dimension or seam replacement.
This high hydrolysis resistant double warp flat yarn dryer fabric uses a double-warp, double-layer construction. The structure is intended to increase paper-contact and wear surfaces, while the stated 300-500 CFM air-permeability range allows the fabric to be considered for different dryer-section positions. Its listed breaking strength is at least 2500 N/cm. It is evaluated for paper machines that need a technically matched balance of dryer-section running stability, fabric construction and operating conditions. Before selecting a replacement, confirm the paper grade, dryer position, speed, fabric width, loop length, seam requirement and any issue such as contamination, tracking or uneven wear.
High-speed paper-machine dryer sections and operating environments where hydrolysis resistance and a double-warp fabric construction are selection factors. Share the machine data and current fabric condition for a position-specific recommendation.
The supplied application notes list High-temperature, high-humidity dryer sections serving cultural and packaging papers. Final suitability depends on the actual machine position and operating conditions.
No single value should be assumed. The supplied schedule gives 300-500 as a configurable range; confirm the target for the exact position.
Provide paper-machine speed, paper grade and basis weight, fabric width, loop length, current-fabric details, seam requirement and the intended machine position. Values not included in the supplied schedule must be confirmed before ordering.
Some constructions and permeability targets may be configurable, but the available design range depends on the machine and position. Treat the listed dimensions as the supplied reference and request written confirmation for the quotation configuration.
For a construction review, send the machine speed, grade and basis weight, width, loop length and current fabric information with your request.
