Embodiment Construction
[0013] Made according to the aforementioned process steps, the product of the present invention can be made.
[0014] The needle-punched hot-melt double-sided filter cloth of the present invention uses the entanglement force, mutual pulling force and cohesion force between fibers to form a certain density, and this density can be determined by the needling frequency, the number of needling passes, and the hot-melt fiber ratio to be controlled. The fiber arrangement of the present invention is a three-dimensional messy structure, which can reduce the resistance of material flow and improve the interception force of impurities; at the same time, by designing the D number of fibers on both sides of the cloth, the ratio of low-melting point skin-core composite polyester fibers can be adjusted. Acupuncture frequency, melting rate, and temperature difference between the two hot rolls form a double-sided structure with a hairy front and a smooth back to improve the particle capture e...

Abstract
The invention provides a needle-punched hot-melt two-side filter cloth and a manufacturing process thereof. The needle-punched two-side filter cloth comprises an upper composite fiber and a lower composite fiber, wherein the upper composite fiber is 85% 3D*51 common polyester fiber and 15% 2.5D*51 low melting point sheath core polyester fiber, and the quantity is 100 g / m <2>+ / -; the lower composite fiber is 95% 3D*51 common polyester fiber and 5% 2.5D*51 low-melting-point sheath-core polyester fiber, and the quantity is 260 g / m<2>+ / -; the composite material is 300 grams per square meter, the thickness is 0.2 millimeters, the air permeability is 1000l / m.s, one side is a smooth surface, and the other side is a double-side filter cloth with a plush surface; the low-melting-point polyester fiber is a sheath core structure, the melting point of the skin layer is 100-1300 DEG C, the melting point of the core layer is 230-2500 DEG C. The cloth has the advantages of low filtering resistance, high filtering precision, high strength and long service life.
Description
technical field [0001] The invention relates to a filter medium applied to an automobile air conditioner filter and an automobile drier, in particular to a needle-punched hot-melt double-sided filter non-woven fabric. Background technique [0002] At present, the filter media of automotive air conditioning filters are mainly made of paper, which has the disadvantages of low filtration efficiency, large resistance, and easy rupture. Contents of the invention [0003] In order to solve the shortcomings of the prior art, the invention provides a needle-punched hot-melt double-sided filter cloth and a manufacturing process. [0004] The needle-punched hot-melt double-sided filter cloth includes an upper layer composite fiber and a lower layer composite fiber, and the upper layer composite fiber is 85% 3D*51 ordinary polyester fiber and 15% 2.5D*51 low-melting point sheath-core polyester fiber composite, quantitatively: 100g / m 2 ±; The composite fiber of the lower layer is 9...
