Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] The invention introduces a method for continuous melt-blown non-woven fabrics, which includes the following specific steps: first, dry the PBT raw material, and then send the PBT raw material to the extruder by the feeder after the drying treatment, and the extruder feeds the PBT pellets Heat and melt, then send the heated and melted PBT to the spinneret at the spinneret die for spinning, and form ultra-fine fibers under gas drafting, the gas is ejected from both sides of the spinneret 2, and the air is compressed The machine 3 first compresses the air and transmits the compressed air to the air heater 4 for heating. The compressed and heated air is ejected in the same direction as the fibers ejected from the spinneret through the gas pipeline connected to the spinneret 2. The high-temperature air It can be 400°C, 410°C, 420°C, etc. The ...

Abstract

The invention discloses a continuous non-woven fabric melt-blowing method and a non-woven fabric. The method comprises the following specific steps that a PBT raw material is prepared, subjected to drying treatment and then fed to an extruding machine through a feeding machine, the particle PBT material is heated and melted by the extruding machine, the heated and melted PBT is fed to a spinneret plate at a mold spinneret for spinning, ultrafine fibers are formed under gas drafting, sprayed to a receiving device moving transversely at a high speed and moving longitudinally at a low speed, and cooled with air to form the non-woven fabric, and then the non-woven fabric is fed to a roller receiving machine to be rolled. The method is simple and high in mechanization degree and production efficiency, and the non-woven fabric meeting medical application can be produced.

Description
