Needlepunch Polyester Nonwoven Fabric — Mechanically Bonded PET Felt

Polyester staple fibres are carded into a web and mechanically entangled by barbed needles. The bond is physical, so the felt keeps loft and permeability, and the polymer gives it better dimensional stability under sustained load and heat than a polypropylene felt of the same weight.

As-needled, calendared and infrared-bonded finishes are available. Calendering compresses and smooths a face; infrared bonding stabilises the surface. Both reduce thickness and surface fibre release and change how the roll behaves in lamination, coating and cutting.

Automotive converters use it in interior, trunk and acoustic layers where heat and load are ordinary service conditions. Filtration users specify it as depth filter media and as support behind a finer layer. Roofing and membrane producers use it as a carrier or protective layer. Furniture and bedding manufacturers use it for padding and construction layers, and industrial users for protective and cushioning felt.

Basis weight, thickness, density, fibre denier, tensile and elongation, thermal behaviour, colour and roll dimensions vary with the manufacturing specification. Filtration and acoustic performance depend on the complete assembly and must not be inferred from the felt alone.

Send the basis weight, roll width, roll length and quantity, together with the application. Where relevant, state the service temperature, any load or elongation requirement, the finish you need, and whether the material will be laminated, moulded, coated or cut.

Allzone confirms basis weight, finish and composition with the supplier before quoting and shares the technical data for the exact material offered. No approval, flammability rating or certification is assumed on this page.
