研制了一套应用于碳纤维生产的伺服控制系统，该系统由PMAC2控制器、伺服控制器、伺服电机及工控机组成，实现对牵伸比的准确控制。
A servo control system composed of PMAC2 controller, servo controller, servomotor and industrial control computer has been developed for carbon fibre production to control the draft ratio precisely.
纺纱是对纤维集合体牵伸加捻的过程。长丝比短纤维需要的捻度少。
Spinning is the process of drawing out and twisting a mass of cleaned prepared fibres. filament yarns generally require less twist than do staple yarns.
