Double Warp Dryer Mesh
SJ16904 is listed as a double warp, double layer high-strength 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 1817-4500 m³/m²·h (90-300 CFM) and is configurable for the machine position. The application notes identify high-speed single-felted and multi-cylinder dryer positions, including packaging, linerboard and corrugating-paper machines. 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-speed single-felted and multi-cylinder dryer positions, including packaging, linerboard and corrugating-paper machines. 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.
SJ16904 is a high-strength double-warp dryer fabric with a double-warp, double-layer construction. The product offers stated air-permeability options of 115, 125 and 285 CFM, allowing the air-permeability range to be considered alongside the actual dryer-section position. Its listed breaking strength is at least 2800 N/cm. This fabric is evaluated where the paper machine requires a durable construction and a replacement discussion based on position-specific operating data. For a useful technical review, provide the paper grade, machine speed, dryer location, fabric dimensions, seam type, current fabric construction and any running concern observed on the machine.
A range of dryer-section positions and paper grades where a high-strength double-warp construction and selectable air permeability need to be reviewed against the actual machine conditions. Technical matching should be based on the specific operating position rather than a generic specification alone.
The supplied application notes list High-speed single-felted and multi-cylinder dryer positions, including packaging, linerboard and corrugating-paper machines. Final suitability depends on the actual machine position and operating conditions.
No single value should be assumed. The supplied schedule gives 1817-4500 m³/m²·h (90-300 CFM) 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.
