Akzo Nobel Faster AG, Germany, have developed a new process for the spinning of fine filament POY yarns. The process, which is covered by patents, utilises a self suction device to cool the filaments after melt extrusion. Details are provided of work carried out on a multiple position pilot unit to assess its potential for spinning filaments from 0.4 to 1 dtex including the design of the cooling unit, yarn path, application of spin finish, spinneret design and the properties of the yarns obtained. It was found that the process offered excellent spinning reliability.
