The production process of black fiberglass tissue involves several key steps. First, raw materials such as glass fibers are combined with a black pigment or dye to color the fibers. These fibers are then melted and extruded into thin strands. The strands are gathered together and woven or laid into a sheet form to create the tissue. This sheet is then treated with a resin to bind the fibers together, resulting in a strong, black fiberglass tissue. The final product is often used in various industrial applications due to its strength and resistance to heat and chemicals.
