Polyester fiber (abbreviated as PET fiber) is a synthetic fiber obtained by polyester spinning formed by the polycondensation of organic dibasic acid and dihydric alcohol. Polyester fiber is mainly made of polyethylene terephthalate.

Polyester felt is a synthetic needle punched felt made from polyester fibers. The polyester fibers are needle punched with a special felting needle, one with small barbs on the end. These barbs pull the polyester into itself, locking together to create a fabric.

Polyester felt is offered in a wide variety of densities and thicknesses to meet your needs. It offers a low cost alternative to wool, and can be used in many industrial and commercial applications. Monarch Textiles manufactures needle punched polyester felt products to meet your specifications.

Polyester felt products offer a range of benefits. Not only is polyester felt less expensive than wool felt, but needle punched polyester felt also provides resistance to organic acids, mildew, bleaches, and other oxidizing agents that could damage the material.
