Meltblown Cloth Meltblown Nonwoven Spinneret Extrusion Mould For 5
Layers Mask
Melt-blown nonwovens uses high-speed hot air flow to draw a thin stream of polymer melt
extruded from the die orifice. Thus, ultra-fine fibers are formed
and collected on a screen curtain or a roller, and at the same
time, they are bonded to each other to form a melt-blown nonwoven fabric.
This spinneret plate for meltblown nonwoven fabric mask making
machine. It is the high precision melt blown spinneret mold. The
small drilled holes for polymer feeding are drilled by high
precision CNC small hole EDM popping machine.
Melt-blown nonwoven fabric is made by entangling fibers while
extruded material from the spinneret in the same time blowing hot
air. The common application is face masks, industrial filters, etc.
Melt blown spinneret size:
Length 300mm and 270mm are available
Feeding hole: drilled with 0.2mm diameter electrode tube, finished
diameter during 0.25-0.26mm.
Technical characteristics for melt-blown nonwovens mould:
1. Die head conventional model: 1.1M-1.6M, also can be customized
according to customer's special requirements.
2. The diameter of the melt nozzle (spinner) is 0.2mm-0.3mm. The
center distance of the spinneret holes is between 0.7mm-0.8mm.
3. Suitable for process temperature below 350, carbon fiber
330-350, PP, PET300
4. Suitable for general output of 30-50KG / hour, special
requirements below 80KG / hour, can also be determined according to
the production line configuration capacity.
EU FFP Serials (EN 149:2001)
| Standard | Basic weight (gsm) | Resistance (Pa) | Filtration efficiency (%) | MAIN USAGE |
| FFP 1 | 40 | 70 | >93% | FFP 1 standard respirator, 3-ply flat mask. 3-ply flat mask |
| 80 | 50 | >93% | bulky and soft product, lower air resistance, higher dust capacity |
| FFP 2 | 45 | 125 | >99% | lower basis weight of FFP 2 standard respirator filter media,
economical and practical product |
| 60 | 110 | >99% | FFP 2 standard respirator, fit for mine, severe air condition
workshops etc |
| 100 | 90 | >99% | lower air resistance and higher dust capacity for high standard
respirator |
| FFP 3 | 90 | 150 | >99.5% | FFP 3 standard respirator, high filtration environment requirement
eg. chemical lab |
Test Method: TSI 8130 @ 0.33 um, 60L/Min, DOP
Marks: This FFP serial product can reach to 99.8% filtration rate
with the air resistance less 160Pa. The parameter is obviously
better than European standard requirement, 99% filtration rate and
300Pa resistance. Same performance is shown in the standard of FFP1
and FFP2.
US N Serials (NIOSH 42 CFR-84 & GB 2626-2006)
| Standard | Basic Weight (gsm) | Resistance (Pa) | Filtration efficiency (%) | MAIN USAGE |
| N 90 | 30 | < 60 | >93% | Economic product, lower cost |
| 60 | < 40 | >95% | bulky and soft product, lower air resistance, higher dust capacity
Can replace 3M 9001 products |
| N 95 | 30 | < 90 | >98% | lower basis weight of N 95 standard respirator filter media,
economical and practical product |
| 50 | < 60 | >98% | N 95 standard respirator, fit for mine, severe air condition
workshops etc |
| 80 | < 50 | >98% | Bulky and soft product, lower air resistance, higher dust capacity |
| N 99 | 80 | < 95 | >99.5% | N99 standard respirator, cup shape mask. |
| N 100 | 120 | < 145 | >99.995% | N100 standard respirator, very high filtration efficiency |
Test Method: TSI 8130 @ 0.33 um, 60L/Min, DOP
Marks: This N99 product can reach to 99.5% filtration rate with the
air resistance less 95Pa. The parameter is obviously better than
N99 standard requirement, 99% filtration rate and 120Pa resistance.
Same performance is shown in the standard of N90, N99 and N100
products.
