ABSTRACT:
A method for producing chemically untreated fire resistant fiber blends includes the steps of separately blowing and carding bundles of selected matrix and staple fibers, respectively, to form separate slivers of each of the two fibers. Given proportions of each fiber are then combined during a common drawing step to form a bulky blended sliver which is then conventionally processed to produce a fire resistant yarn. The yarn is suitable for knitting or weaving to provide fabrics which far exceed current government fire resistant standards.
