Abstract
A bicomponent fiber is disclosed, in addition to systems and processes for making the bicomponent fiber. The bicomponent fiber can include a glass core and a polytetrafluoroethylene (PTFE) sheath circumferentially enclosing the glass core, wherein the bicomponent fiber has a diameter between approximately five micrometers and approximately twenty micrometers.
Claims20
A bicomponent fiber comprising:
- a glass core;
- and
- a polytetrafluoroethylene (PTFE) sheath circumferentially enclosing the glass core;
- wherein the bicomponent fiber has a diameter between approximately five micrometers and approximately twenty micrometers.
1 more element
A system for making a bicomponent fiber, the system comprising:
- a container having an inlet and an outlet;
- an aqueous dispersion within the container, wherein the aqueous dispersion includes polytetrafluoroethylene (PTFE);
- and
- a heated surface configured to receive a core fiber coated with the aqueous dispersion from the outlet of the container, wherein the heated surface sinters the coated aqueous dispersion into a sheath.
1 more element
A process of making a bicomponent fiber, the process comprising:
- passing a glass fiber through an aqeuous dispersion including polytetrafluoroethylene (PTFE) to coat the glass fiber with the aqueous dispersion, thereby yielding a PTFE coat of the glass fiber;
- and
- contacting the PTFE coat of the glass fiber with a heated surface to form a PTFE sheath, wherein the PTFE sheath circumferentially encloses the glass fiber, thereby yielding the bicomponent fiber.
