TEXTILE OF LONG HIGH-PURITY ALUMINA FIBER, LONG HIGH-PURITY ALUMINA FIBER USED FOR PRODUCING SAID TEXTILE, AND METHOD OF PRODUCING THEM.

摘要

A textile of long high-purity alumina fibers having an alumina content of 95 wt% or above and a fiber diameter of 5 to 20 mu m; a hybrid textile composed of such long high-purity alumina fibers and long high-strength fibers having a tensile strength of 200 kg/mm<2> or above; method of producing these textiles; a long high-purity alumina fiber useful for producing such textiles; and method of producing such fiber. These textiles are useful as the material for the reinforcing fiber of fiber-reinforced composite material, heat insulation material, and so on.
