Feature
PFM Screen's spunbond/meltblown forming belts are engineered to the precise technical demands of high-speed nonwoven production — delivering controlled air permeability, reliable static dissipation, dimensional stability, and clean web release across every beam type and process combination.
01 Controlled Air Permeability Calibrated aperture and open area ensures uniform airflow for filament deposition and cooling — critical for consistent fabric basis weight distribution | 02 Static Dissipation Conductive bronze or carbon-fiber warp yarns bleed off electrostatic charge from PP/PE filaments — eliminating fiber fly-back and formation defects | 03 Clean Web Release Smooth monofilament surface releases the formed web cleanly at the belt end without fiber pull, lint, or surface marking — critical for medical and hygiene fabrics | 04 High-Speed Dimensional Stability Heat-set polyester construction maintains width and length stability at line speeds above 1,000 m/min — no tracking deviation, no belt stretch |
PFM Screen offers two antistatic yarn technologies for PP and PE spunbond lines. Both dissipate electrostatic charge; the choice depends on conductivity requirement, fiber fineness, and line speed:
Bronze Wire Warp — Model A8848 ● Warp: 0.68 mm PET + 0.45 mm Bronze monofilament ● Weft: 0.8 mm PET monofilament ● Warp density: 12 wires/cm / Weft: 6.8 wires/cm ● Air permeability: 9,887 m3/m2h ● Best for: standard-speed PP spunbond S and SS lines | Carbon Fiber Warp — Models A8848-1 / A22504 ● Warp: 0.68 mm PET + 0.45 mm Carbon, or 0.5 mm PET + 0.52 mm Carbon ● Air permeability: 8,500–12,000 m3/m2h ● Higher conductivity than bronze — superior static bleed-off for fine-denier or high-speed PP lines ● Best for: SMS/SMMS composite lines, high-speed hygiene fabric production |
The hydrolysis-resistant belt series uses flat-profile PET bicomponent monofilaments (e.g., 0.55 x 0.38 mm cross-section) that resist moisture and steam-related degradation — a key failure mode on lines running PET-based spunbond or high-humidity environments. The flat warp profile reduces surface marking on delicate medical and hygiene nonwovens.

Q1: What is the difference between an antistatic belt and a hydrolysis-resistant belt for spunbond production? Antistatic belts incorporate conductive warp yarns — either bronze monofilament or carbon fiber — to bleed off electrostatic charge generated when PP or PE polymer filaments contact the forming belt. This prevents fiber fly-back and formation defects on the web. Hydrolysis-resistant belts use flat-profile PET monofilaments engineered to resist moisture and steam degradation — a key failure mode on PET-based spunbond lines or high-humidity production environments. For PP or PE lines, antistatic is typically the primary specification; for PET lines or hygiene-grade medical fabrics, hydrolysis-resistant is preferred. Both variants are available with custom widths and seam types to suit your machine. |
Q2: What is a spiral belt used for in spunbond or meltblown production, and how does it differ from a woven forming belt? Spiral belts are open-coil PET structures used primarily on suction drums in spunbond and meltblown lines, where maximum air permeability is required to pull the fiber web down onto the forming drum surface. Unlike flat woven belts, spiral belts have a three-dimensional loop structure that delivers ultra-high airflow (1,920–12,000 m3/m2h depending on loop size) without leaving a woven mesh imprint on delicate microfiber or hygiene webs. Spiral belts are specified by loop size — super, large, medium, or small — which determines the permeability and web-support characteristics for your target basis weight and fiber denier. |
Q3: Which PFM Screen belt is compatible with Reifenhauser Reicofil RF4 and RF5 spunbond/SMS lines? Reifenhauser Reicofil RF4 and RF5 lines run PP and PE spunbond, meltblown, and composite SMS/SMMS configurations. For the spunbond (S) beams, PFM Screen recommends the antistatic series (A8848 with bronze warp, or A8848-1/A22504 with carbon warp for higher-speed lines) or the hydrolysis-resistant series for PET-based RF5 installations. For meltblown (M) beams or suction drums, the spiral belt series is the standard specification. Share your current belt model number or machine drawing when inquiring — PFM Screen will confirm exact compatibility and cross-reference the correct replacement specification within 24 hours. |
Q4: How do I select the correct air permeability for my spunbond or meltblown line? Air permeability selection depends on your line speed, target basis weight, and suction box vacuum level. Higher production speeds and lighter fabrics (10–20 gsm hygiene grades) typically require higher-permeability belts to ensure the vacuum system draws filaments uniformly onto the forming surface. Lower-speed lines or heavier fabrics (80–120 gsm geotextiles) can use lower-permeability belts for better fiber support and retention. PFM Screen offers models from 1,920 to 12,000 m3/m2h across the three series. Share your current belt specification — model, air permeability, line speed, and basis weight target — and PFM Screen's engineers will confirm or optimize the selection. |
Q5: Can PFM Screen supply forming belts for both the S beams and M beam on the same SMS or SMMS line? Yes. PFM Screen routinely supplies full belt sets for SMS, SMMS, SMMMS, and SSMMS composite lines — antistatic woven belts for the spunbond (S) beams and spiral belts for the meltblown (M) beams or suction drums, in the same order. This ensures consistent belt specifications and compatibility across all forming stages. Specify your process code (e.g., SMS or SMMS), machine OEM, and number of beams when requesting a quotation so PFM Screen can prepare a complete belt package for your production line. |
Q6: What seam types are available for spunbond and meltblown forming belts? PFM Screen offers three seam configurations: (1) Self-seam (endless woven or self-joining) — the standard for most spunbond woven belts, providing the smoothest joint with minimal web marking; (2) Spiral seam — used for spiral belt connection on suction drums, interlocking coils without visible joint marks on the fabric; (3) Double-layer self-seam — for reinforced joint strength on high-tension, wide-width installations. The correct seam type depends on your line tension, belt width, and whether marking-free joints are critical for your fabric grade. Contact PFM Screen with your machine and application details for a seam recommendation. |
Q7: How do I order a replacement belt if I don't have the exact belt model number? If you don't have the current belt model number, provide the following: (1) machine brand and line type (e.g., Reicofil RF5, CL Nonwoven SMS); (2) belt width in mm; (3) belt length or circumference in mm; (4) a photo of the current belt surface and seam area; (5) the polymer you process (PP, PE, or PET) and typical production speed. PFM Screen's engineers will identify the correct belt specification and supply a cross-reference recommendation within 24 hours. WhatsApp photos directly to +86 153 6967 9157 for the fastest response. |
Q8: What is the minimum order quantity and typical lead time for spunbond/meltblown forming belts? PFM Screen accepts orders from a single custom belt — there is no fixed minimum order quantity. Standard lead time for custom-engineered spunbond/meltblown forming belts is typically 2 to 4 weeks after drawing confirmation and order placement, depending on belt width, series, and seam configuration. Rush orders may be accommodated for critical production situations. Contact PFM Screen via WhatsApp (+86 153 6967 9157) or email (polyestermesh@pfmscreen.com) with your specification for a formal quotation and confirmed lead time within 24 hours. |
