Glass Fabric Finishes

Many fiberglass fabrics will require finishing which is determined by the particular application or end use of the fabric. Fabrics that are not finished are called greige, loom state, or untreated fabrics.

The BGF Industries finishing processes include but are not limited to the removal of the sizing and binder that was applied to the glass fibers to facilitate weaving. This is accomplished by heat cleaning, scouring, or other specialized methods. After cleaning, the fabric may be treated with chemical agents that interact with the chemistry and processes used by our customers or may be left as is.

Sizing and binder may be left on the fabric with various chemical agents applied directly over the greige/loom state fabric.

For glass fabric finishes performing as intended, applying a finish after weaving is frequently necessary. The application and end-use performance criteria will significantly determine the optimal finish for a project. With so many finishes, appropriate selection necessitates a thorough understanding of the production environment, process chemistry, and intended application.
