Abstract (en)

The fine denier corespun yarn (10) is formed on an air jet spinning apparatus and comprises two components, including a core (11) of high temperature resistant fibers, and a core wrapper (12) of low temperature resistant fibers surrounding and covering the core (11). The high temperature resistant fibers of the core (11) are selected from the group consisting essentially of aramid fibers (Kevlar and Nomex), polybenzimidazole fibers (PBI) and heat stabilized/oxidized polyacrylonitrile fibers. The low temperature resistant fibers of the core wrapper (12) are natural fibers, such as cotton. The corespun yarn (10) is fabricated into a fabric and subjected to a high temperature flame environment, the low temperature resistant fibers of the core wrapper (12) are charred but do not melt, drip or exhibit afterflame or afterglow, and the charred portion remains in position around the core (11) and maintains the same type of flexibility and integrity as the unburned fabric.
