Mask Melt-blown Cloth Spinneret Die Mould
1. overview and principle of meltblown cloth equipment
the melt-blown method is a method for preparing fibers by blowing polymer melts with high-temperature and high-speed airflow to rapidly draw them. (melt-blown cloth extruder, melt-blown cloth equipment, melt-blown cloth production line)
after the polymer chips are heated and pressed into a molten state by a screw extruder, they reach the spinneret hole at the front end of the nozzle through the melt distribution flow path, and after extrusion, they are refined by two converging high-speed and high-temperature air flows to refine .
the refined fibers are cooled and solidified on the screen device to form a melt-blown nonwoven fabric.
2. components of meltblown cloth equipment
meltblown heads, automatic charging system equipment components, ultrasonic cleaning machines, air heaters, centrifugal fans, screw extruders, meltblown web forming machines, meltblown offline winding machines, meltblown offline slitting machines and other key equipment.
3. the core components of meltblown cloth equipment
spinneret
the spinneret for melt spinning is a representative spinneret for the manufacture of synthetic fibers such as polyester and nylon. the thermoplastic resin is heated and melted, extruded through the spinneret in air or water at a certain speed, and cooled spinning method of solidifying into fibers
the most core technology is the small nozzle on the spinneret. this nozzle not only has a small size of only 0.15mm, but also needs to process a complex hole pattern on such a small nozzle. the processing is extremely difficult, and the nozzle processing process requires months. if the processing accuracy is not high, the melt-blown cloth finally produced will not meet the corresponding technical requirements, which will affect the protective performance of the mask.
structure of melt-blown cloth spinneret
according to the shape of the spinneret, the structure of the spinneret can be divided into three forms: round, sector and rectangle. at present, round and rectangular plates are mostly used at home and abroad. to suit different chemical fiber spinning occasions, the round spinneret is divided into flat type, flange flat type, flat ring, flange ring, etc .: the rectangular spinneret is divided into flange rectangle and flange groove rectangle, etc. , mostly used for spinning short fibers with many holes.

Melt blown is a one step process to make fabrics from polymer.
The thermoplastics chips are fed through main dosing units & these chips are melted by means of the extruder. This extruder then extrudes the melt, which is then filtered & metered at a constant rate. This filament comes out from a single raw of spinneret orifice. It has a self bonding property but for coagulation & for better random laying hot air flow is provided.
The web generated is immediately passes among the Spunbond webs followed by pre-bonding rolls & finally through calendar for thermal bonding.
The main purpose of melt blown fabric is to provide barrier property for the liquid.
Sometimes the treatment like antistatic or hydrophilic are given to the fabrics & after drying the fabrics are wound in the winder as a roll form.
Unique characteristics such as water repellence or permeability or UV stability can be obtained by incorporating additives to the raw materials or applying different agents to the fabric.
Characteristics of Meltblown fabrics are:
The main desired characteristics expected for melt blown nonwoven fabrics are:
Adjustable Pores And Capillary Structure
Excellent barrier properties
Filament size 1 -3 �?�µm
High Elasticity
High Filtration capability
Isotropic formation- this means that the fibers are randomly distributed in the machine direction (MD) and cross-machine direction (CD).
Large Area-to-weight ratio
Self-bonding
The weight of the melt-blown fabrics in gram per square meter (GSM) should range from 4 g/m2 to over 1000 g/m2.
Very good thermal insulation for apparel application
Weak tensile properties
Wicking Properties
Application of spun-bond nonwoven fabrics:
Sanitary and Hygiene:
Sanitary napkins,
Baby diapers and
Incontinence diapers
Medical and Surgical:
Gowns,
Face masks,
Caps,
Drapes, etc
Other Miscellaneous Applications:
Filtration Material,
Agriculture,
Oilsorbents
Hot-melt adhesives
Headliners, etc
