Abstract: Glass fiber materials, a kind of filter medium, have advantages of high filtration accuracy and large holding capacity of pollution. It is usually composited with nonwoven materials to improve its processability and service life by overcoming the poor folding ability and pressure resistance. However, the air permeability of this kind of composites will be decreased caused by the hot melt adhesive coating method. In this paper, this issue is addressed by creating a melt-blown fibrous bonding layer of hot melt resin rather than just coating a compact film between glass fiber medium and spunbond nonwoven materials. By this approach, the loading amount of melt-blown fibrous layer plays a significant role in the filtration performance of this filter medium. The results show that a high peel strength can be achieved but without compromising the permeability when loading 8 g/m² melt-blown fibers. And, considering the properties of the product and the production, a filter medium product with good mechanical properties and filtration performance can be fabricated when setting the loading amount of melt-blown fibers, gauge, temperature, and speed of hot calender at 8 g/m², 0.3 mm, 120℃ and 15 m/min, respectively.
