Production system for novel filtering material non-woven fabric

Abstract

Provided is a production system for a novel filtering material non-woven fabric. The system comprises a drying tower, a screw extruder, a precision filter, a spinning cabinet, a tensioning roller, a draw roll, an air-flow stretching system, a web former, heat-setting machine, a cooling roller, and a winding roller. The discharge port of the drying tower is connected with the feed port of the screw extruder. The discharge port of the screw extruder is connected with the precision filter. The precision filter is above the spinning cabinet. The tensioning roller, the draw roll, the air-flow stretching system, and the web former are below the spinning cabinet from top to bottom in sequence. In the system, PET which is melted and filtered enters the spinning cabinet and respectively passes through a first spinneret plate and a second spinneret plate, and a fiber web formed by the PET, manufactured by a spinning device, is directly sent to the heat-setting machine to solidify. The fiber web is not influenced by external forces, and a product is fluffy, and product gas permeability is greatly improved, so the manufactured novel filtering material non-woven fabric can be preferably used in a low pressure difference filtering device. Therefore, a problem that production of a novel filtering material non-woven fabric is difficulty is solved.

Description

technical field [0001] The invention relates to a non-woven fabric production system, in particular to a non-woven fabric production system of a novel filter material. Background technique [0002] The fiber web formed by the spinning equipment in the existing non-woven fabric production system is sent to the hot rolling mill by the mesh curtain for consolidation. Under the same grammage, the product is compacted, the thickness is relatively thin, and the air permeability of the product is small. It is suitable for high pressure differential filter equipment, and the market demand is small. However, general filter materials cannot be used in low-pressure differential filter equipment, and whether they can be used depends on the air permeability of the product. Therefore, the applicant uses polyethylene terephthalate (PET for short) as the raw material. This material is acid-resistant, insect-resistant, UV-resistant, and high-temperature resistant. , the existing non-woven ...

Problems solved by technology

[0002] The fiber web formed by the spinning equipment in the existing non-woven fabric production system is sent to the hot rolling mill by the mesh curtain for consolidation. Under the same grammage, the product is compacted, the thickness is relatively thin, and the air permeability of the product is small. Suitable for high pressure differential filter equipment, the market demand is small

However, general filter materials cannot be used in low-pressure differential filter equipment, and whether they can be used depends on the air permeability of the product.

Therefore, the applicant uses polyethylene terephthalate (PET for short) as the raw material. This material is acid-resistant, insect-resistant, UV-resistant, and high-temperature resistant. , the existing non-woven production system using PET has poor production effect, therefore, the market urgently needs a non-woven production system of a new type of filter material made of PET
