  • Description: 섬유질 재료의 부직 웹은, 전형적으로 적어도 50% 이상의 기계 펄프 및 바람직하게는 약 60에서 - 실질적으로 100% 기계 펄프인, 기계(예를 들면 CTMP, CMP, TMP, 또는 쇄목) 펄프를 사용하는 폼 처리로 제조된다. 제조된 웹은, 합성 수지 또는 라텍스로 함침, 그루빙, 플리팅, 합성 수지 또는 라텍스의 경화 등에 의해, 자동차용 여과지로 바람직하게 제조된다. 예를 들면, 폼 처리로 제조된 시트는 적어도 60% 이상의 기계 펄프 및, 레이온, HPZ, 무명, 울, 및 그것의 혼합물일 수 있는, 적어도 5% 이상의 장섬유를 가질 수 있다. 필터 요소는 자동차 오일 필터 케이싱, 자동차 에어 필터 케이싱, 자동차 연료 필터 케이싱, 또는 자동차 차실 필터 케이싱과 결합하여 전형적으로 위치된다. Non-woven webs of fibrous material are made by the foam process using mechanical (e.g. CTMP, CMP, TMP, or ground wood) pulp, typically at least 50 % mechanical pulp and desirably from about 60 - substantially 100 % mechanical pulp. The webs produced are preferably made into automotive filter paper, such as by impregnation with resin or latex, grooving, pleating, curing the resin or latex, etc. For example, a sheet made from the foam process may have at least 60 % mechanical pulp and at least 5 % long fibers, which may be rayon, HPZ, cotton, wool, and mixtures thereof. The filter element is typically placed in combination with an automotive oil filter casing, an automotive air filter casing, an automotive fuel filter casing, or an automotive cabin filter casing.
