The Fundamentals of Fiberglass Fabric

Fiberglass fabric are inorganic, nonmetallic materials, generally derived from natural materials, such as quartz, limestone, sand, kaolin and dolomite, among others. With the development of modern material science and technology, several routes for fiberglass fabric production have been invented. There are two methods of producing materials; woven fiberglass fabrics, and non-woven fiberglass fabrics.

Woven Fiberglass Fabric

The best known fiberglass fabric is created in the weaving process. At least two systems of threads are interwoven here perpendicularly. Weft threads are being pulled crosswise through lengthwise taut, tear durable warp threads. The edges are usually woven more densely, creating salvedges, which often contain information about the fabric printed on them. Because the warp threads are stretched, so it can be woven evenly, most of fabrics are strong, inflexible and stable (predictable), which is undoubtedly conducive to learning of sewing. By changing color or type of warp and weft threads, unlimited variety of fabrics can be created. Usage of a different type of weave changes the way the fabric handles.

Non-woven Fiberglass Fabric

The oldest method of creating materials is bonding / splicing the fibers together. The process of manufacturing felt fabrics can be a good example – it consists of soaking wool, compressing it, which results in entanglement of fibers, and ultimately creating a compact structure. Such created non-woven fiberglass fabric doesn’t fray or rip, and can be cut in any direction. The best known non-woven fiberglass fabric are: waddings and interfacings.

Glass fibers are inorganic, nonmetallic materials, generally derived from natural materials, such as quartz, limestone, sand, kaolin and dolomite, among others. With the development of modern material science and technology, several routes for fiber glass production have been invented. Among these routes, industrial production of glass fibers in combination with chemicals, such as boric acid, soda ash, etc. (as raw materials), is mostly preferred. In this route, the mixture is melted and simultaneously drawn, spun or drown into fine fibrous materials in a molten state under pressure. According to the composition and performance, glass fibers are divided into non-alkali, medium, high and customized or special glass fibers. Glass fiber has several properties, such as high temperature resistance, non-flammability, low hygroscopicity, corrosion resistance, high tensile strength, good chemical stability, good electrical insulation and thermal insulation, amongst others. Owing to these properties, fiberglass is prevalently used and has become an indispensable part of the consumer electronics, automobiles and tele-communications industries. Glass fibers can be made into various forms, such as yarns, fabric and belts, among others.

Fiberglass fabric is a material, woven or non-woven, made from glass fibers. These glass fibers are textured in such a way that air pockets are created within glass traps. The resultant fiberglass fabric has high strength, low density and high thermal insulation, among other properties, owing to which it finds application in several industrial as well as defense sectors. Due to its thermal insulation property, fiberglass fabrics are used in application where high temperature resistance and thermal barriers are required. These fiberglass fabrics are classified mainly into E- and S-class. In industrial application, E-Glass fiberglass fabrics are preferred owing to their strength. However, S-class fiberglass fabrics are made up of high strength-rigidity glass material and used in high-end applications.
