The basalt yarn uses basalt roving with filament diameter of 7um and 9um then be twisted in 60-100 per meter.Usually,the twist direction is Z or S.This yarn can be used to produce basalt fabric.
l Electric insulating yarns and threads
l Unidirectional fabrics with high temperature resistance, high elastic modulus, and high strength
