Since1953 Dalian Synthetic Fiber Research & Design Institute Co., Ltd. has done a lot of work in the technology and equipment of composite filament spinning, especially the high efficient multi-ends conjugate yarn spinning production line with compact structure of spin beam, reasonable distribution of melting pipes and short melt stay time. A special insulating method is used to create different temperatures for two kind of melt, so as to meet different process requirements with different raw materials. The spin pack with special heat conductive structure, raise the heat transfer efficiency and solve the technical problem of that uneven temperature on the big spinneret.
