Mesh for nonwoven production
Nonwoven lines use mesh belts to support the web while air or water passes through it. Hengfeng manufactures this family in-house for processes such as spunbond, meltblown, spunlace and needle-punch support. Uniform air distribution, a controlled surface and stable tracking matter more here than drainage in the papermaking sense, so the belt is specified from the line layout, air or water pressure, web weight and the joining arrangement.
Where the belt runs
Typical positions include web forming and conveying, hydroentanglement support, drying and thermal bonding lines. The belt must stay dimensionally stable under tension and temperature while allowing the process air or water to pass evenly. Uneven permeability shows up as web weight variation, so uniformity is checked as carefully as the average value.
What is configured
Weave structure, yarn material and diameter, surface character, permeability uniformity, finished width and length, seam type and edge design are agreed together. Anti-static requirements, temperature exposure and cleaning practice are recorded as conditions. Where food, hygiene or medical product requirements apply, we document what can and cannot be confirmed rather than assuming compliance.
Manufacturing and verification
The belt is produced on Hengfeng’s own monofilament, weaving, heat-setting, seaming and inspection lines. Dimensional stability, seam quality and permeability uniformity are checked before dispatch, with the test method stated on the written specification.
Configurable dimensions
- Weave structure and layer construction
- Monofilament material, diameter and surface character
- Permeability target and uniformity requirement with stated test conditions
- Seam or endless joining method
- Finished width, length and edge design
- Temperature, cleaning and anti-static requirements
- Web support and release behaviour
Information to send for a configuration review

Industry reference specifications (public sources) — not Hengfeng measurements
These are publicly published, industry-common reference values transcribed from third-party supplier and competitor pages on 9 November 2026, with the source and test conditions shown beside each table. They are NOT Hengfeng test results, NOT a Hengfeng product specification, and NOT a performance or supply commitment. They exist so that a technical discussion can start from comparable terms. Final values are confirmed in a written specification against your machine conditions.
Nonwoven production forming mesh examples
Nonwoven forming belts are published under process-specific codes. The two examples below show how differently suppliers state air permeability — one with a pressure, one without.
| Code / process | Structure | Warp / weft density (roots/cm) | Yarn Ø (mm) | Thickness (mm) | Weight (g/m²) | Air permeability |
|---|---|---|---|---|---|---|
| CXW25408-165 | 1.5-layer forming mesh | 29.5–30.5 / 14.5–15.5 | Warp Ø0.24 PET; weft Ø0.45 PET / Ø0.47 PA | 0.99 | 470 | 6500 m³/m²·h at 100 Pa / 411.3 CFM at 125 Pa |
| WFB504 | White round-yarn mesh, spunbond / meltblown | 20.5 / 10.0–11.0 | Warp Ø0.50; weft Ø0.60 | 1.70 | 990 | 9000–12000 m³/m²·h |
Test conditions & comparability
CXW25408 explicitly states 100 Pa for the m³/m²·h value and 125 Pa for the CFM value. WFB504 states no test pressure. A second WFB504 page lists 9500 m³/m²·h, 1.68 mm and 1000 g/m² for the same code — another reason to confirm the written specification.
- The WFB504 source also lists heat-setting tension 60 N/cm, heat-setting temperature 180 °C, custom width < 5.5 m and length < 90 m, and endless / reverse-plug / spiral-ring seam options.
- Uniformity across the width matters as much as the average permeability value for nonwoven web formation.

Air-permeability values are comparable only when the unit, differential pressure and test method match. The tables above come from different sources, some without a stated test condition, and cannot be used as acceptance criteria or a performance promise. Binding values are those in the mutually confirmed written specification.
Frequently asked questions
Is average permeability enough to specify the belt?
No. Uniformity across the width is as important as the average value, and both must be stated with the test method used to measure them.
Do you publish standard nonwoven belt models?
We do not publish a fixed Hengfeng model catalogue. The forming-mesh examples below are industry-common reference values from public supplier pages, with their sources and differing test conditions shown; they are not Hengfeng measurements. A written specification is issued after reviewing the line layout and process conditions.
Are these belts manufactured by Hengfeng?
Yes, in-house on our own monofilament, weaving, heat-setting, seaming and inspection lines.
Hengfeng manufactures this family in-house. The parameter tables on this page are publicly published, industry-common reference values transcribed from third-party supplier and competitor pages, with each source and test condition shown next to the table. They are NOT Hengfeng measurements, NOT a Hengfeng product specification and NOT a performance or supply commitment. Model designations, permeability, dimensions and seam details are configured against your machine conditions and become binding only in a written specification.
