Document Type and Number:
Japanese Patent JP6313450
Kind Code:
B2
Abstract:
A method for making an expanded, and optionally multi-component and/or colored PTFE monofilament is disclosed. The method includes forming a first paste by mixing a PTFE powder with a hydrocarbon solvent; forming an extrusion preform by pressing the first paste into a form; curing the extrusion preform by exposing the extrusion preform to a first temperature for a first time duration; forming a green monofilament by extruding the first paste through a die; expanding the green monofilament by exposing the green monofilament to a second temperature for a second time duration, the second time duration occurring after the first time duration; stretching the green monofilament substantially along a longitudinal axis of the green monofilament, the stretching the green monofilament occurring after the expanding the green monofilament; and sintering the green monofilament after the stretching the green monofilament.
