  7. Abstract:
  8. Air filter paper is a combination of cellulosic, polymeric and resin materials with a certain permeability to air, which is used to prevent dust from entering the internal combustion process.The purpose of this research was to study and make air filter paper, based on which 4 samples of automobile air filter paper were produced. Samples with a combination of 2 types of cellulose fibers, imported short Kraft fibers and long Bangladeshi Kenaf fibers (skin) and one type of polymer fibers, Polyester fibers with a type of self-networking water-based Acrylic resin with glass conversion temperature (Tg) About 33 degrees Celsius and in the range of 20% by weight with a mass of about 120 g/m2 were prepared in the laboratory and their physical and mechanical properties were evaluated under standard conditions.The samples made in this study were compared with two samples of imported heavy air filter paper from Ahlstrom Italy and H&V UK, which obtained the following results.In measuring the pore diameter, the pore diameter of the third sample was lower than that of the two imported samples and the diameter of the fourth sample was close to that of the two imported samples, which absorption much smaller particles which show that the reduction of pores, did not reduce Air permeability and this result shows the Air permeability quality and high absorption of the third and fourth samples compared to the two imported samples. In measuring mechanical properties such as tensile strength and burst resistance of the third sample the results were closer to the two imported samples.Finally, two types of paper made from a combination of Kenaf fibers and Kenaf-Polyester fibers had suitable standard properties and were closer to imported samples in terms of mechanical and physical properties
