Abstract
The invention relates to refractory fiber cloth and belongs to the field of composition fiber manufacturing. The invention provides the refractory fiber cloth; warp and weft of refractory fiber are interwoven to form the refractory fiber cloth; the weft is chosen from at least one of the refractory fiber and a fixed fiber; the refractory fiber takes MgSiO3, Sb2O3, SiO2, ZnO, TiO2 and Al2O3 as substrates, a polymer as a matrix, and is prepared by a melt spinning method. The fiber has the characteristics of high intensity, good fire resistance, high flexibility and the like, and can be widely applied to the fields of metallurgy, petroleum, chemical industry, machinery and the like.
