Problems solved by technology

[0002] After the needling operation of needle felt, the distance between the fibers of the needle felt moves due to the needling, which makes some holes between the fibers of the needle felt too large, which is easy to cause dust leakage during filtration. The friction between the felt and the filter equipment generates static electricity, which can easily absorb dust particles and cause the blockage of the dust filter holes, and the water vapor in the dust circulation air can also easily cause the blockage of the dust filter holes

Abstract

The invention belongs to the field of polyester needled felts, and relates to a polyester needled felt with high dust removal efficiency. The polyester needled felt comprises needled felt fibers, a wear-resistant layer is arranged on the upper surface of the needled felt fibers, a leveling coating is connected to the lower surface of the needled felt fibers, metal wires are connected to the interiors of the needled felt fibers, and a waterproof breathable film is connected to the upper surface of the needled felt fibers close to the lower part of the wear-resistant layer. Through the arrangement of the metal wires, splicing openings and the waterproof breathable film, the metal wires can limit the positions of needled felt fibers, large position movement cannot occur under the action of external force, and the situation of dust leakage due to large holes in individual parts because of needling is avoided; the waterproof breathable film can block small water drops in air flow flowing along with dust; when the needled felt fibers are wetted, dust is prone to being attached to the wetted needled felt fibers, filtering holes of the needled felt are blocked, and dust filtering of the needled felt is affected, while, with the polyester needled felt adopted, the above situation can be avoided.

Description

technical field [0001] The invention relates to the field of polyester needle-punched felt, in particular to a polyester needle-punched felt with high dust removal efficiency. Background technique [0002] After the needling operation of needle felt, the distance between the fibers of the needle felt moves due to the needling, which makes some holes between the fibers of the needle felt too large, which is easy to cause dust leakage during filtration. The friction between the felt and the filter equipment generates static electricity, which can easily absorb dust particles and cause the blockage of the dust filter holes, and the water vapor in the dust circulation air can also easily cause the blockage of the dust filter holes. Contents of the invention [0003] (1) Purpose of the invention [0004] In order to solve the technical problems existing in the background technology, the present invention proposes a polyester needle-punched felt with high dust removal efficienc...
