ABSTRACT:
The disclosure is of a high temperature resistant, composite yarn useful in the manufacture of woven and knitted fabrics for high temperature applications. The yarn of the invention comprises a core of a twisted, multi-filament or spun yarn and an outer coating or sheath of a high temperature resistant, synthetic, polymeric resin. The multi-filaments or staple fibers of the core are selected from high temperature resistant, synthetic materials. The outer coating comprises a plurality of coating layers intimately bonded to each other and to the twisted core so as to give the composite yarn of the invention an outward appearance and other characteristics of a monofilament. The composite yarn of the invention combines the properties of a monofilament and a multi-filament or staple yarn and is useful in weaving high temperature resistant fabrics.
