Abstract
A spunbonding apparatus includes at least one nozzle, a coagulating tank, a deformation region, a slit passage, and a drawing flow pump. The nozzle extrudes at least one spinning solution. The coagulating tank contains coagulating liquid to coagulate the spinning solution into at least one fiber. The deformation region is located between the coagulating tank and the nozzle. The slit passage is connected to the coagulating tank and allows the fiber to pass therethrough. The drawing flow pump provides a drawing flow to the slit passage.
