Abstract
The invention relates to a manufacturing method of a glass fiber continuous felt. The manufacturing method comprises the following steps of drawing out dried glass fiber proto-filaments through a creel to form proto-filament tows, enabling the proto-filament tows to penetrate through 6-12 pairs of swing arms, transversely throwing and laying the proto-filament tows onto a mesh belt through the swing arms in a reciprocating mode to form a felt blank, evenly scattering a bonding agent on the felt blank, curing the felt blank in a drying furnace, and flattening, trimming and taking up the felt blank to obtain the glass fiber continuous felt. The manufactured glass fiber continuous felt is even in forming and high in interlayer bonding strength and tensile failure strength, meanwhile has excellent high-temperature-resisting performance and can be widely applied to chemical plants, thermal power plants, cement plants, lime factories, coking plants, metallurgical plants, asphalt plants, paint spraying plants and high flues and hot air filtration of electric-arc furnaces, oil-fired boilers and incinerators, and the production efficiency is remarkably improved.
