Summary:PURPOSE: A method of preparing a ceramic thread guide for a fabric weaving machine is provided, which provides the ceramic thread guide having good strength and wear-resistance. CONSTITUTION: The method comprises steps of: (i) stirring a mixture of ceramic powder and organic binder at a temperature of about 150-180°C; (ii) pulverizing the mixed lump of step (i) with an injecting hopper; (iii) injection molding a thread guide(1) having a plural of thread guide holes(2)(3), a groove(4), an end jaw(5) and a screw hole(6) at a temperature of about 100-190°C and a pressure of about 100-160 kilogram/square meter; (iv) gradually heating the molded thread guide at a temperature of about 400-600°C to decompose organic matter; (v) trimming the molded thread guide and firing it at a temperature of about 1,500-1,600°C; and (vi) cutting -processing the thread guide according to a use. (1) 청구범위에 기재된 발명이 속한 기술분야 본 발명은 직물 제직기용 세라믹 실 가이드 제조방법에 관한 것이다. (2) 발명이 해결하고자 하는 기술적 과제 종래 금속재 실 가이드 본체에 구멍을 뚫고 여기에 원통형 실안내구를 끼워 접착하는 구성에서 제조공정이 번거롭고 견고하지 못한 점과 금속재 실 가이드의 문제점을 해결하고자 함. (3) 발명의 해결방법의 요지 실안내구 일부를 세라믹으로 대체하면서 저온상태에서 필요한 실안내 구멍을 복수개 형성한 다음 고온소성 가공후 지지대에 결합하는 것이 요지임. (4) 발명의 중요한 용도 직기에 장착되어 실을 안내하는 용도임.
