Mask Material: Meltblown Fabric | Nonwoven Fabric | Hot Air Cotton | Nose Wire | Earloops
Face mask materials are the base of masks for qualified testing.
For flat earloop 3ply face masks, the face raw materials are pp non-woven fabric(external and interior layer), melt-blown fabric as the middle filter material, nose wire, and earloops to get a better facial fit.
While for the KN95 face mask, more layers are applied, one or two meltblown fabrics are added to achieve a better filtration efficiency, and hot air cotton(es fiber) is also used to produce a KN95 face mask.

Face Mask Material: Meltblown Fabric(Filter material)
Meltblown fabric, also called meltblown cloth, meltblown nonwoven, which is one kind of special nonwoven or spunbond. Meltblown cloth’s raw material is mainly polypropylene, which has good filtration, shielding, heat insulation, and oil absorption. Can be used for air and liquid filtration materials, isolation materials, absorbent materials, mask materials, warm materials, oil-absorbent materials and wiping cloth, etc.
The meltblown fabric we offer is for mask filter application use and has special specifications, which help the final mask can meet the requirements of varied standards.

Mask Material: PP Nonwoven Fabric
Nonwoven fabric, or spunbond, is one of the important material to make all kinds of masks, TESTEX supplies nonwoven fabric suitable for producing qualified face masks.
To validate the quality of the non-woven fabric, we sample and test each roll in our lab:
| Product Name | Color | GSM | Specifications |
| Flat mask Outer/Inner Spunbond | Blue/White/Pink | 25 g/m² | Width: 175 mm |
Mask Material: Earloop
Earloop is welded on medical mask bodies to help the face mask fit well on the wearer’s face well, high-quality ear loop can be easily welded on the masks by ultrasonic ear loop welding machines, with a limit to nonblocking situations.
Check how we validate the Max. elongation test quality of earloop in the video below, more related tests like earloop PH test, ear loop formaldehyde test, please contact us.
| Product name | Round Mask Earloop |
| Width and length | 3 mm, 770 m/kg |
| Material | Spandex / Nylon |
| Colour | White |
Electret masterbatch, which results in a long duration of the electrostatic adsorption capacity of the meltblown.
PFE test, BFE test, Synthetic blood penetration test, Differential pressure test, Breaking force test, Final mask testing.
Use the meltblown fabric on mask machines to validate whether meltblown fabric is suitable for long time production
*All tested samples will be processed under high temperature and low temperature (high temperature 70 degrees, low temperature minus 30 degrees), simulating the aging of natural time for 1 year.
