PURPOSE:Glass fiber is modified in its cross section to increase cooling efficiency immediately after drawing whereby light reflection and refraction are increased and the strength is developed enough to be used as a reinforcing material. CONSTITUTION:Glass fibers are made by means of bushings having a plurality of convex nozzles into modified cross section such as oval, triangle, dumb-bell, T-form, Y-form, cross or star. Thus, the outer surface area of the glass fibers is increased so that cooling efficiency is increased immediately after drawing. Thus, extension by tension is prevented, resulting in no fluctuation in thickness. The glass fibers are twisted and woven to give tuff and stiff glass fiber fabrics. |
