摘要
The present invention relates to a basalt coa manufacturing method, a manufacturing apparatus, and a basalt coa prepared using the same, a process for releasing basalt sand having a fineness of 300 to 1000 deniers, and a step of applying a sizing agent to the released basalt sand; , A step of heating the loosened basalt sand to 100 ° C. to 180 ° C., a step of releasing the first flame retardant yarn having a fineness of 20 to 200, a step of winding the first flame retardant yarn outside of the basalt sand and braided with basalt cores; and Basalt cored yarn is manufactured by the process of winding up the said basalt cored yarn. The basalt cores thus prepared have the property that the function of flame retardant yarn is added to the intrinsic properties of the basalt fibers.;Basalt, Flame Retardant Yarn, Corea, Plywood, Heating, Sizing Agent
