DOUBLE FINISHED YARN'S MAKING METHOD

摘要

A partially oriented yarn composed of polyester having a molecular orientation rate of at least 3x10-3 and the thermoplastic synthetic filament having a molecular orientation rate of at least 150x10-3, is processed by the air jet machine in which the cross number per meter of the yarn is at least 10. The processed yarn is forced to twist by the belt type twisting machine.
