PURPOSE: To obtain the subject textile useful for insulation gloves, etc., having abrasion resistance by uniformly coating a roving composed of a plurality of ceramic fibers with an elemental carbon containing no metal. CONSTITUTION: Ceramic fibers 10 having 5-20μm diameter in number of 100-1,000 are spun from an organic sol 12 composed of a mixture containing precursor substances of Al2 O3 , B2 O3 and SiO2 , passed through a baking furnace 14 and drawn together to form a roving 16. The roving is coated with a metal- free organic lubricating sizing material 18 in such a way that the amount of the sizing material 18 comprising a poly(ethylene glycol), a starch, etc., is 2-3% based on the weight of the ceramic fibers. The roving is passed on a pair of hot cans 20 and 21 many times, dried and taken up on a winder 22. The plurality of rovings are combined to give the objective textile. The textile is heated in an inert atmosphere such as nitrogen at 600-800 deg.C not changing the crystal structure of the ceramic fibers so as to remove the organic substances and to form 0.25-0.4% of a coating film of elemental carbon based on the weight of the ceramic fibers on the surface of the ceramic fibers. |
