Engine oil filter element end cover non-woven fabric material and manufacturing process thereof

Abstract

The invention discloses an engine oil filter element end cover non-woven fabric material and a manufacturing process thereof. The engine oil filter element end cover non-woven fabric material comprises a first polyester staple fiber web layer, polyester reinforced cloth and a second polyester staple fiber web layer, all of which are sequentially fixed. The manufacturing process includes the following steps that S1, the polyester reinforced cloth and 100% polyester staple fibers are provided; S2, the 100% polyester staple fibers serve as raw materials to be fed into a bale opener for bale opening, are subjected to coarse opening through a coarse opener and subjected to cotton blending through a cotton blending box, enter a fine opener for fine opening, pass parallel cotton feeding box to enter a carding machine, and are dually carded through the carding machine, a single layer of polyester staple fiber web is made, the web is subjected to dual cross lapping through a cross lapper, multiple layers of polyester staple fiber webs are formed, meanwhile, the middle of the polyester reinforced cloth is fed to the position between the two polyester staple fiber web layers, needling web fixing is carried out through a pre-needling machine, a main-needling machine and a face repairing needling machine, and the parts are wound into semi-finished coil materials; S3, after calendering, shaping and mirror surface singeing are carried out, the semi-finished coil materials are coiled into coil materials; S4, the coil materials are slit and packaged into finished coil materials.

Description

Technical field: [0001] The invention relates to the technical field of oil filter element end caps, in particular to a non-woven fabric material for an engine oil filter element end cap and a manufacturing process thereof. Background technique: [0002] The oil filter element is the soul part of the oil filter. The existing oil filter elements mostly use metal end caps or plastic end caps. The material cost and manufacturing cost are high, the production process is complicated and cumbersome, and the key is that it is not easy to degrade and is not conducive to environmental protection. There are also some cardboard materials used, which have low strength. Invention content: [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a non-woven fabric material for the end cover of the oil filter element. [0004] In order to solve the above-mentioned technical problems, the present invention adopts the following first techn...
