Overview and principle of meltblown cloth equipment
Overview and principle of meltblown cloth equipment
Melt blowing is a method of preparing fibers by injecting polymer melts with high temperature and high speed air flow to make them rapidly stretched. (meltblown cloth extruder, meltblown cloth equipment, meltblown cloth production line 132-1008-3690)
After the polymer slices are heated and pressurized into a molten state by a screw extruder, they reach the spinneret hole at the front end of the nozzle through the melt distribution channel. .
The attenuated fibers are cooled and solidified on the screen curtain device to form a meltblown nonwoven fabric.
How is meltblown cloth produced?
The equipment for meltblown cloth production is meltblown machine or meltblown cloth production line equipment. The meltblown cloth production line consists of the following parts:
1. Screw extruder: melt the slices.
2. Metering pump: Control the output and the fineness of the fiber to continuously deliver the melt to the spinneret.
3. Melt filter: filter the impurities in the melt.
4. Conveying net curtain: make the meltblown fibers evenly received and spread on the net
5. Spinning box: After the fibers are ejected, they are stretched with high-speed hot air immediately to blow the fibers to become ultra-fine fibers.
6. Feeding system: It consists of 3 measuring hoppers, which are used to measure white chips, masterbatch and additives respectively.
7. Hot air blower and heater: It provides the temperature and pressure of the hot air used in the spinning air stretching. It is heated by electricity and consumes a lot of electricity.
8. Coiler: It adopts fully automatic coiling, and packs the meltblown cloth into rolls.
What is the raw material for non-woven?
For this reason the choice of fiber is very important for nonwoven manufacturers. The commonly used fibers include natural fibers (cotton, jute, flax, wool), synthetic fibers (polyester (PES), polypropylene (PP), polyamide, rayon), special fibers (glass, carbon, nanofiber, bi-component, superabsorbent fibers).
Frequently Asked Question
Do you have any question?
Melt blowing is a conventional fabrication method of micro- and nanofibers where a polymer melt is extruded through small nozzles surrounded by high speed blowing gas. The randomly deposited fibers form a nonwoven sheet product applicable for filtration, sorbents, apparels and drug delivery systems.
Meltblown fabrics are mostly used in: Isolation materials. Air Filtration Equipments. Mask materials – N95 Masks, PPE Kit, Coverall for Healthcare Industry.
Melt-blown filter cartridges are made from polymer fibers that are pressed and sintered, then melt-blown onto a rotating spindle to create cylindrical cartridges. These filters are often used in sediment applications, but they do not transfer any sedimentary taste or odor to filtered liquids.
