Glass Fiber Fabric: Types, Properties, and Uses

Most glass fiber fabrics are made from extremely thin glass fibers and used for various industrial purposes. Since all glass fiber fabric types are made similarly and from similar ingredients, they have similar properties. This fiber fabric is more commonly known as fiberglass, and its versatility makes it a unique industrial textile material. Glass fiber fabric is categorized based on its properties and uses.

Uses of Glass Fiber Fabric

Glass fiber fabric is a heat-resistant textile and completely non-combustible. Moreover, it provides high mechanical strength and can resist up to 550 degrees Celsius under constant conditions and 600 degrees Celsius for short periods. Glass fiber fabric is most suitable for drapes, curtains, and blankets used in high-temperature conditions in the industry.

Some other rigid fabrics are used for making jackets, covers, and other mechanical items. Moreover, these fabrics also come with optional coatings such as graphite, vermiculite, and aluminum foil for improved heat resistance. They’re also used to manufacture printed circuit boards, structural composites, and several special-purpose products. Most flame-proof boats, automobiles, hot tubs, and roofing pipes are made from glass fiber.

Strength and Elasticity

Glass fiber cloth is one of the strongest materials and second to stainless steel. Since the fabric comprises various glass fibers, it becomes hairy when the filaments roughen. This also occurs when the draperies rub against rough objects such as radiators or window sills.  

This fabric is virtually inelastic so that curtains and draperies made from glass fiber fabric won’t sag out of shape or stretch out.

Easy to Drape

The fine fibers in glass fiber fabrics offer excellent pliability and flexibility. As a result, they can be woven into fabrics of fine draping quality, especially with the proper finish. You can easily sew these fabrics by hand or by machine by using a sharp needle and quality cotton thread. Making long stitches with low tension will ensure greater durability.

Easily Washable

Considering the glass fiber fabric’s smoothness, dust and dirt don’t cling as easily. Cleaning these fabrics is quick and simple as you can simply clean them with a damp cloth. Even if you completely immerse the fabric in water, the temperature of the water and the detergent you use won’t affect the material.
