Request a QuoteA pleated filter pattern fabric separator is a textile‑processing component that uses a series of uniform folds to increase effective surface area while maintaining low flow resistance. The geometry enables efficient capture of loose fibers, lint, or particulate contaminants from fabric streams without significant pressure drop. This design is particularly suited to continuous‑operation lines where consistent separation performance directly impacts product quality.
The separator consists of a base fabric sheet that is mechanically pleated to a defined pitch and height, creating a series of alternating peaks and troughs. Pleat height typically ranges from 2 mm to 6 mm, while pitch (center‑to‑center distance) varies between 4 mm and 12 mm depending on the required filtration efficiency. The pleats are stabilized by heat‑setting or ultrasonic bonding to prevent unfolding under tension.
Common base materials include polyester (PET) for its high tensile strength (~55 MPa) and dimensional stability, polypropylene (PP) for excellent chemical resistance to acids and alkalis, and nylon (PA) for superior abrasion resistance. Each polymer exhibits distinct moisture regain values—PET around 0.4 %, PP negligible, and PA up to 4 %—which influences selection based on operating humidity and cleaning protocols.
| Parameter | Typical Value | Unit | Notes |
|---|---|---|---|
| Pleat Height | 2–6 | mm | Adjustable via die set |
| Pleat Pitch | 4–12 | mm | Determines open area ratio |
| Base Fabric Weight | 80–200 | gsm | Influences stiffness and pleat retention |
| Tensile Strength (MD) | 45–60 | MPa | Typical for PET base |
| Air Permeability | 150–350 | L/(m²·s) at 100 Pa | Varies with pleat geometry |
In carding and drawing lines, the pleated separator removes fly fibers that would otherwise accumulate on rollers, reducing wear and preventing yarn defects. During fabric finishing, it captures loose lint from stenters and calenders, maintaining consistent surface quality. The increased surface area from pleats allows higher contaminant loading before cleaning cycles are required, thereby improving machine uptime.
Pleat geometry can be tailored to specific process requirements: higher pleat height increases filtration efficiency but may raise pressure drop, while finer pitch improves particle capture for sub‑micron debris. Edge treatments such as heat‑sealed tapes or ultrasonic welds prevent fraying during high‑speed operation. Widths are commonly supplied from 100 mm up to 2000 mm, with lengths cut to customer‑specified roll sizes or supplied as continuous lengths on request.
Each production lot undergoes dimensional verification using laser scanning to confirm pleat height and pitch within ±0.1 mm. Burst strength is measured according to ISO 13937‑2 to ensure the pleated structure withstands operational tensions. Porosity tests assess air permeability, and visual inspection checks for pleat uniformity and bonding integrity. Documentation of these tests is available upon request.
Minimum order quantities typically start at 200 linear meters for standard widths, with sample lengths of 5 meters provided for evaluation. Production lead time averages 10–15 working days after final design approval, depending on material availability and pleat tooling complexity. Products are packed in rigid cardboard cores with protective polyethylene wrapping to prevent deformation during transit, and palletized for ease of handling.
