A corespun yarn (10) includes a high temperature resistant continuous filament fiberglass core (11) and a low temperature resistant staple fiber sheath (12) surrounding the core (11). The corespun yarn (10) is useful in the formation of fine textured fire resistant flame barrier fabrics (19) for use as mattress and pillow ticking, bedspreads, mattress covers, draperies, upholstery, protective apparel, tenting, awnings, field fire shelters, for use as a substrate of backing for coated upholstery fabrics and as a flame barrier for use beneath upholstery fabric. The core (11) of high temperature resistant continuous filament fiberglass comprises about 20% to 40% of the total weight of the corespun yarn (10) while the sheath (12) of low temperature resistant staple fibers surrounding and covering the core (11) comprises about 80% to 60% of the total weight of the corespun yarn (10). The total size of the corespun yarn (10) is within the range of about 43/1 to 3.5/1 conventional cotton count. This corespun yarn (10) may be woven and knit in fine, non-plied form and extends the range of fineness of fabrics below heretofore achievable limits.
