Abstract

The invention discloses a glass fiber polyester needled felt. The needled felt comprises a needled felt body, wherein a glass fiber precursor pierces the interior of the needled felt body; PTFE protective layers are arranged on the upper surface and the lower surface of the needled felt body; the needled felt body comprises a base cloth layer; a first superfine fiber layer and a second superfine fiber layer are respectively arranged on the upper surface and the lower surface of the base cloth layer; and a first composite fiber layer and a second composite fiber layer are arranged on the sides,away from each other, of the first superfine fiber layer and the second superfine fiber layer correspondingly. The glass fiber precursor pierces the interior of the needled felt body in a needling manner, so the needled felt is free of adhesive suture lines in the forming process, and a product is more attractive; the needled felt body is well protected under the action of the PTFE protective layers, so the service life of the needled felt body is prolonged; and the needled felt has the advantages of long service life, good dust removal effect, high strength and high abrasion resistance.

Description

technical field [0001] The invention relates to the technical field of needle-punched felt, in particular to a glass fiber polyester needle-punched felt and a manufacturing method thereof. Background technique [0002] Needle-punched felt is a filter material with reasonable structure and good performance. It uses glass fiber as raw material, needles the carded chopped glass fiber felt with needles, and uses mechanical methods to make the felt between the glass fibers and the felt layer The fibers are entangled with each other between glass fiber and reinforced glass fiber base cloth, and the fiber web is reinforced to form a felt-like non-woven filter material. [0003] At present, most of the existing needle-punched felts are stitched with adhesives, which makes the aesthetics poor. In addition, the existing needle-punched felts have a short service life and poor dust removal effect, which is not conducive to people's use. Contents of the invention [0004] The object o...
