Embodiments generally relate to devices and methods for production of fibers and threads for use in electronic device manufacturing. Described here, fibers can be produced and manipulated using a dual-surfaced sizing material. The dual-surfaced sizing material has a surface which binds a fiber and a surface which binds a resin. Thus, the dual-surfaced sizing material can be left attached to the fibers without adversely affecting the resin binding in later production steps.
