Fiberglass, drawn from spinning glass (woven glass), is a few dozen micrometers in diameter (thinner than a hair). These fibers will then lose the disadvantages of bulk glass such as brittle, easy to crack, but become more mechanical advantages.
Glass fiber has become more mechanical, soft as silk but has a strength far exceeding that of stainless iron iron of the same magnitude. Therefore, glass fiber is used in many fields to bring high economic efficiency as one of the important construction materials.

Create different types of fiberglass like: glass fiber E (good electrical conductivity), glass fiber D (good insulation), glass fiber A (high alkali content), glass fiber C (chemical resistance high), glass fiber R and glass fiber S (high mechanical strength). Type E glass is the most common type, the less common type (1%) used in specific applications.
Producing glass fiber by centrifugal drawing process:
In this process the glass is melted in a furnace and poured onto a rotating refractory clay plate at high speed and attached at the periphery of a large number of teeth. Glass is attached to the plate, the disk is heated by the fire from a furnace, but at the same time it is pulled into fibers by centrifugal force. These fibers are blown out onto a stationary table and rolled into a cooling drum. This is a process of producing short fiberglass like glass wool that is used in heaps without spinning.
Manufactured by mechanical broaching process:
Glass is cooked in a furnace. The glass is melted and flows into the combustion chamber first, its underside is attached to the fiberglass spinning molds (bushings) made from precious metal (Rudi or Platin) to withstand high temperatures. These spinning molds are drilled in small holes through which molten glass fibers flow. After a sizing process (silicon), these fibers are transferred to a high-speed center axis, which pulls them into small, thin and parallel strands. Thus obtained continuous strands similar to man-made filament yarns.
These fibers can be obtained in a virtually homogeneous process, which is wrapped in a web and used directly in the same sense as thermal or sound insulation.
Produced by the process of using liquid solution:
Pulling is done by high pressure steam jet or compressed air being blown from one edge into the molten glass fibers from a furnace through a wire drawing mold. Under the action of these rays, the fibers are broken into several short sections, which are coated with lubricant during the manufacturing process. The resulting yarns are rolled and a drum is either used in the correct sense (insulating coatings) or continuous pieces or coarse fibers from yarns which can be further spun into yarns.
