Melt Blown Fabric

USEON provides high quality meltblown fabric for N95/Medical face mask.

Photos of Melt Blown Fabric

The normal medical mask contains 3 layers of non-woven fabric, spunbond + meltblown + spunbond.

Meltblown fabric is the heart of the mask. It is the filter layer in the middle of the mask, which can filter bacteria and prevent the spread of germs.

Melt blown fabric is a film made of high melt index polypropylene. The fabric is composed of many criss-cross fibers stacked in random directions. The fiber diameter ranges from 0.5 to 10 microns, and the fiber diameter is about one-third of the hair diameter.

USEON provide meltblown fabrics with stable quality. We produce our products from PP resin raw materials to meltblown line. We can control the quality of each step.

Melt Blown Fabric Structure

As shown in the figure below, the gap of the melt blown cloth is so large. But the size of the COVID-19 is very small, about 100 nanometers (0.1 microns).

So how does the melt blown cloth filter the virus in the environment?

There are two main reasons:

  1. The virus cannot exist independently. Its transmission routes mainly include secretions and droplets when sneezing. The size of the droplets is about 5 microns. A qualified melt blown fabric can filter particles of this size.
  2. The melt blown fabric needs electret treatment, which is a kind of static fiber filter. The droplets containing viruses will also be electrostatically adsorbed on the surface. So, it cannot pass through the melt blown fabric.

Factors Affecting the Quality of Meltblown Fabric

The main factors affecting the quality of melt blown cloth include:

  • Quality of Raw Materials
    Raw materials are crucial. Poor raw materials will affect the uniformity of the meltblown fabric, resulting in a failure to meet the filtering effect standards.
  • Stability of Production Equipment.
    The very cheap small production machine is not stable, and the cloth they produce is almost all garbage·
  • Personnel Experience
    Only professional production staff can produce excellent melt-blown cloth.

Meltblown Fabric Filt Efficiency Test

“True and false” melt blown fabrics are more difficult to identify and require professional testing.

To ensure that each of our rolls of cloth can meet high standards, we will take a piece of cloth from the production line for inspection every half an hour.

Meltblown Fabric Package & Shipping

If by air, the fabric will be packaged in carton.

  • Carton size is 550*550*550mm
  • Net weight have two types:
    • 15.6kg/carton, 2 rolls, each roll with width 260mm, length 1200m, 25gsm
    • 15.75kg/carton, 3 rolls, each roll with width 175mm, length 1200m, 25gsm

If the fabric is transported by sea, it will be packaged by pallet, which contains 12 cartons each.

We can also pack, transport, deliver products according to consumer needs and requirements.
