MaterialNatural and Soft Fibers
Felt
Compressed textile material
Felt is a dense, compressed nonwoven of wool, part-wool or synthetic fiber. It gives a continuous, compliant surface for controlled polishing, wiping, liquid transfer and sealing. Its behavior depends almost entirely on its density and fiber content, so those have to be specified.
What is felt?
Fibers matted and pressed into a solid sheet, roll, wheel, pad or shaped part. Densities run from about 0.15 to 0.70 g/cm³ and thicknesses from 1 mm to 25 mm, in grades from soft to hard. Wool and part-wool felts are graded in standards such as SAE J314.
Where is felt used?
In our range: machine guide rail brushes, seal strip cleaning brushes, filter bag cleaning brushes, sponge cleaning brushes and paper machine roller brushes, where a felt strip or pad wipes, seals or carries oil.
How hot can it run?
Ambient to about 120°C for the cited wool felt; data quote 100–150°C depending on the fiber. Synthetic felts differ, so the fiber is chosen for the temperature.
Where does felt fall short?
Felt with an unspecified density or fiber content gives unpredictable pressure, absorption, wear and chemical response. It also holds liquid and soil, so it is not for hygienic wet cleaning.
What should you tell us?
The job, wipe, seal, polish or oil, the fiber and density if known, the thickness and shape, the temperature, and any liquids.
Questions buyers ask about Felt
Where is felt used on brushes?
On guide rail wipers, seal strip cleaners, oiling strips and polishing pads, where a continuous compliant surface works better than bristles.
What do I need to specify for felt?
The fiber, wool, part-wool or synthetic, the density, the thickness and the shape. Without them, pressure and wear are unpredictable.
How hot can felt get?
About 100–150°C depending on the fiber; the cited wool felt is rated to about 120°C.

Share what the brush works on, the temperature and chemicals it meets, the form you need — strip, disc, roller or hand brush — the quantity and a drawing or photo.
We reply to every request within 24 hours, with a quotation or with the questions we need answered first. If the brush can be made on our existing tooling, we make the sample directly. If it needs new tooling, we quote a sample fee and a tooling fee, and the sample fee is credited against the bulk order. Need an NDA first? We sign yours before you send drawings, and the files you send are never shown to other customers.
