摘要： A diesel engine secondary oil filter is formed from a punched tinned steel spiral lock seam center tube, with a flanged cap at one end and a flanged threaded outlet at the other end. A layer of polyester non-woven media is wrapped in one wind around the center tube. A yarn is wound is a 27-diamond pattern in a first yarn section out to two inches outer diameter. The yarn is tied off. Knitted socks are first placed partially on axial ends of the first wound section, leaving half of the socks extending over the ends. A sheet of activated carbon paper about 1/6 of an inch thick and about 52 inches long is rolled onto the filter cartridge with about nine turns. The carbon paper is made of a cellulose paper impregnated with about 50% activated carbon powder by weight. After the activated carbon paper is wrapped around the first wound section, the free ends of the socks are pulled over axial ends of the activated carbon paper layers, and an outer yarn is wound around the activated carbon paper out to a four inch outer diameter. The yarn is a cotton fiber paper fiber blend, in which the paper fibers are created from crushed and torn two inch strips of thin loose fiber paper such as, for example, paper like toilet paper. The cotton and paper fibers are blended, carded and spun into yarn before the winding of the yarn. The inner wound section is made of that cotton paper fiber blend, or polypropylene yarn, or a yarn comprising two strands of cotton paper blend spun yarn and polypropylene yarn.
