Yes, PTFE fluoropolymer is available as a fiber, not just a film.

PTFE fiber is quite suitable for weaving into virtually any pattern imaginable.
The physical properties of PTFE fiber are superior to the properties of a PTFE film, yet a fabric woven of PTFE fibers can be processed to simulate the surface texture of a PTFE film.

Remarkably, despite the non-stick reputation of PTFE, certain fabrics woven of PTFE fiber can be bonded to any material using common resins or glues, if suitably designed. Yet it will retain the same non-stick, non-slip properties that you expect from PTFE.

Fabrics woven of PTFE fiber exhibit none of the cold-flow problems of PTFE films, so they are more stable under extremes of heat and pressure.
A fabric woven of PTFE fiber exhibits higher tensile strength and abrasion resistance than a comparable PTFE film. Moreover, a fabric woven of PTFE fiber also exhibits greater chemical and steam resistance than PTFE films.

Self-lubricating bearings incorporate fabric woven of PTFE fiber. Both the static and dynamic coefficients of friction of fabrics woven of 100% PTFE fiber are virtually identical, allowing for the elimination of “stick-slip” behavior in self-lubrication bearing applications. Because PTFE fibers are processed to a higher degree of molecular orientation than their resin counterparts, the stress-strain properties and resistance to cold flow of fabrics woven of PTFE fiber are markedly improved over those of PTFE films. Fabrics woven of PTFE fiber in resin-impregnated or composite bearings are very stable, quiet, and reliable. Because they require no lubrication, they do not contribute to equipment contamination and require less maintenance. Bearings incorporating fabrics woven of PTFE fiber are commonly used in aerospace and automotive applications, office machines, and off-road equipment.

PTFE bearings require adhesion to a rigid material forming the body of the bearing. Being non-stick, PTFE materials inherently resist such adhesion. Stern EWS facilitates polymeric adhesion by weaving 3-D fabrics, with PTFE fiber on one side interwoven with fiberglass (or other resin-compatible fiber) on the reverse side. Brown PTFE fiber on one side, white adherent fiber on the other. Furthermore, Stern EWS bearing fabrics limit the permeability of the bonding resin through the fabric to effect the designed coefficient of friction of the manufactured PTFE bearing surface.
