Fiberglass as we know it today is typically of the nonwoven variety. Fiberglass mats and glass fiber textiles comprise a significant portion of the fiberglass market, and nonwoven fabric was actually the origination point for many modern textile technologies.
What is Nonwoven Fiberglass?
A nonwoven fabric is a fabric-like material made from both long and short fibers. The fibers are laid into place then bonded together in one of several ways: via chemical means, heat treatment, or mechanically.
Nonwoven fabrics are often strengthened with the use of a backing agent. They can be single-use but are inherently very durable. They can be made for a variety of functions including absorbency, porousness, stretch, flame retardancy, thermal insulation, among many others. When made with glass fibers, nonwoven fabric provides excellent insulative properties and when layered, lightweight strength properties.
Where is Nonwoven Glass Fiber Used?
One of the most common uses of nonwoven fiberglass is in the roofing industry. Typically made as a “staple nonwoven,” this kind of glass product is produced after cut fibers are wet laid into mats. Wet laid fiberglass mats are also described as “glass tissue” and are almost always bonded with a curtain coater such as a latex emulsion or polymer solution.
Because glass fiber mats are so insulative, they’re also utilized for building applications such as firewalls and thermal protection. The flexibility provided by nonwoven glass mats makes them ideal for advancing industries such as automotive and aerospace. Industrially, nonwovens are often employed to provide filtration in the form of boxed filters, or even as media deniers. Because it is so versatile, nonwoven glass fiber’s uses are practically unlimited.
