Manufacturing method of a complex filter having high performance and a complex filter formed therefrom

摘要

The present invention is a composite filter that can be used and cabin air filters, air conditioning or air cleaning filters for the automotive as relates to a method and a composite filter formed therefrom, the composite filter production process of the present invention (S1) comprising the low-melting high-melting Inc. Saga preparing a web consisting of mixed short fibers; (S2) forming a non-woven fabric having a bulky when applying heat to one surface of the web, a high-melting binder yarns are each other due to the molten low-melting yarns; (S3) comprising the deodorant spray powder on the upper surface of the bulky non-woven fabric; (S4) depositing the meltblown nonwoven fabric on top of the sprayed deodorant powder; And (S5) comprises the step of laminating a spun-bonded nonwoven fabric on the meltblown nonwoven fabric. According to the production method of the present invention, the filtering properties and deodorizing properties can be produced a composite filter that is expressed at the same time, it is possible to increase the retention rate and filling rate of deodorant powder spray inside the filter is effective to improve the deodorizing properties.
