What is spinning? Spinning is the process whereby a material, usually a polymer, is shaped into a bundle of filaments, called a fiber. In order to shape a polymer into a fiber, the polymer must be brought into a processable liquid state.
An air handler for collecting air discharged from a melt spinning apparatus. The air handler includes an outer housing having walls defining a first interior space. One of the walls has an intake opening for receiving the discharge air. Another wall has an exhaust opening for discharging the air. The intake opening is in fluid communication with the first interior space.
