meltblown nonwoven manufacturing process


Using hot air spray, hot polypropylene is extruded from the fine holes of the nozzle of the spinneret to make it extend in a fibrous shape, and then gathered on a conveyor belt to form a fiber web according to its self-welding property. Many small nozzles are arranged on the spinneret, with a diameter of only. The molten polypropylene flow from the nozzle is extended by a high-speed air flow and concentrated on a moving conveyor belt to obtain a melt-blown cloth.

1. Equipment description:
This unit uses polypropylene PP special material to be plasticized and enter the melt-blown die head flow channel. After being evenly distributed, it enters the spinneret. The most critical layer of filter material.
 
B. The production principle of meltblown cloth:
 
Using hot air spray, hot polypropylene is extruded from the fine holes of the nozzle of the spinneret to make it extend in a fibrous shape, and then gathered on a conveyor belt to form a fiber web according to its self-welding property. Many small nozzles are arranged on the spinneret, with a diameter of only 0.15 mm. The molten polypropylene flow from the nozzle is extended by a high-speed air flow and concentrated on a moving conveyor belt to obtain a melt-blown cloth.


2. Process flow of meltblown production line
PP raw material feeding --- melt extrusion --- filtration --- metering --- air heating and compression --- melt blowing --- molding --- static electricity --- winding
3. Features of production line
The melt-blown non-woven production line is stable, high-yield and efficient. The spun-bonded non-woven fabric produced has a uniform, strong strength, good air permeability, non-toxic and odorless, and meets environmental standards. Non-woven fabrics, construction non-woven fabrics, industrial non-woven fabrics, agricultural non-woven fabrics, disposable products for hotels and other non-woven and industrial fabrics, etc.

Fourth, the main configuration list of the production line
No. Part Name Quantity
1 Single screw extruder 1
2 Filter 1
3 Melt pump 1
