Basics
- A Process for Manufacturing Nonwoven Fabric of a very fine nature
- Used mainly for filters, but also has many other applications
- Not to be confused with Blow Molding
- Uses fine nozzles for plastic which are surrounded by high velocity air to essentially atomise it
- Melt-blown plastic is a material for making N95 masks, or HEPA filters as well.
- Similar Processes are used for Fiberglass, Basalt Fiber...And Cotton Candy, although this is typically done with a linear, rather than radial output (see the patent section)
Patents
- Melt-blown plastic, original Exxon patent - [1]
Feasibility Study
What level of technology is required to produce the machine?
- Precision die with small holes
- Near-sonic air flow
- Hot air generation
SME Search
As a first step - contact researchers in the field for rapid learning on the technology.
