SJ22804 Flat Yarn Dryer Mesh
SJ22804 is a double-layer flat-yarn dryer fabric built for paper grades where surface finish is critical. By pairing a flat warp with a round weft, the fabric presents a smooth, low-marking paper-contact side that helps minimize wire marks and supports a clean, uniform dried sheet. The 1.45 mm caliper and 22 /cm warp density give the fabric stable runnability across multi-cylinder dryer sections, while the open structure sustains steady heat transfer. Air permeability is supplied as a configurable range (90–300 CFM) so the same construction can be tuned to different dryer positions and machine speeds rather than committing to a single fixed value. SJ22804 is suited to machines that prioritize sheet appearance — such as coated and high-surface-quality grades — where a flat contact surface reduces the risk of impressed fabric patterns. As with all Hengfeng dryer fabrics, final air permeability, seam type, and loop length are confirmed against the specific machine drawing and operating window before production.
Key Features
- Double-layer flat-yarn construction with a smooth, low-marking paper-contact side
- Stable runnability from a 1.45 mm caliper and 22 /cm warp density
- Configurable 90–300 CFM air permeability to suit different dryer positions
- Open weave sustains steady heat transfer in multi-cylinder sections
Technical Specifications
Applications
SJ22804 is intended for dryer sections producing paper grades with strict surface-quality requirements, where the flat-yarn contact side reduces impressed marks on the finished sheet. It is commonly considered for coated and other high-finish grades running across multi-cylinder dryer sections, where sheet appearance and uniform drying matter more than maximum air permeability.

Selection Notes
Air permeability for SJ22804 is configured per dryer position rather than fixed. When requesting a quotation, provide the paper machine width, section position (single-tier, top/bottom cylinder group), machine speed, paper grade and basis weight, the required loop (endless) length, and the specification of the fabric currently in use. These parameters let our technical team propose a warp/weft density and permeability window that matches your drying profile.
Frequently Asked Questions
Can the air permeability be changed after the fabric is woven?
No. Air permeability is set by the weave (warp/weft density and yarn profile) and is fixed at production. Choose the target window during ordering using your machine position and speed.
Is SJ22804 suitable for high-speed machines?
It is intended for surface-quality-driven grades rather than maximum permeability. Suitability depends on your machine profile; share the operating window so we can confirm the right configuration.
What seam/loop options are available?
Seam and loop length are confirmed from the machine drawing. Provide the required loop length and any seam-type preference when you request a quote.
