ABSTRACT:
Provided are non-woven constructions and fabrics comprising polypyridazole short fiber; the short fiber characterized by an average filament tenacity of at least 15 grams per denier; an average filament modulus of at least 500 grams per denier; an average filament density of at least 1.6 grams per cubic centimeter; an average filament length of 30 to 100 millimeters; and an average filament denier per filament of 0.1 to 10; wherein the construction is substantially free of matrix.
