There are several ways for producing fine denier fibers, such as conjugate spinning, melt blowing, electro-spinning, etc.. Each of these methods has its own merits and demerits. A new technology for manufacturing micro fibers was devised. The idea of this equipment was to apply a centrifugal force on the molten polymer to elongate the spun fiber. The angular velocity of the spinneret, nozzle hole diameter, and melting temperature were controlled to determine their effects on the fiber diameter. The results showed that <0.1 denier fibers could be produced swiftly and economically. The simple machine design enables the operator to access the machine with little or no experience in fiber spinning, and leads to an almost maintenance-free machine compared to other spinning apparatuses.
