Heat treated multilayer knitted textile of liquid crystal polymer fibers and modified polyacrylonitrile fibers, and process for making same

This invention describes a special two-layer fabric where the outer layer is made from modified polyacrylonitrile (like modacrylic) and cotton, and the inner layer is made from liquid crystal polymer fibers (like HBA/HNA filaments). The fabric is created by heating it while it's being dyed, which causes the outer layer to shrink and tighten the knit. The claims specify precise temperature ranges for heating and specific knit densities for the outer layer.
