摘要

本研究主要是設計整組高速分纖機構藉以生產50丹尼以下聚酯低丹尼單絲，利用複絲紡製較高丹尼的纖維，再應用本研究的分纖機構進行分纖工程，將原本6根或10跟組合的PET複絲型態的高丹尼纖維，經分纖工程分製成6或10根的低丹尼單絲筒紗。
分纖機台主要整合張力控制、分纖、捲取機構以達成將複絲分纖之目的。分纖張力控制在每丹尼0.9~1.3克，捲取張力維持在每丹尼1.0~1.5克之間，可得較佳的單絲捲取成形性。隨分纖速度的提高，單絲的伸度受張力作用呈現些微下降，伸度的變異係數均維持在15%以內，強度的變異係數維持在5%以內，均能符合市場產品的需求。分纖後單絲的沸水收縮率有小幅增加，但能呈現穩定的趨勢。生產20丹尼單絲其分纖時受機台影響程度較大，均勻度之變異也較生產50丹尼單絲為高。

The purpose of the study designed a series of high speed fiber dividing device to produce fine mono-polyester-filament which less than 50 denier. The multi-filament was used by dividing engineering, multi-filament which was consisted of 6 or 10 monofilament to produce 6 or 10 monofilament cheeses using dividing device.
The dividing device mainly combined three parts which included tension control, dividing mechanism and take up device to divide multi-filament into monofilament. The cheese shape of the monofilament was better when the dividing tension controlled between 0.9~1.3g/d, and the take up tension controlled between 1.0~1.5g/d. With increasing dividing speed, tensile elongation of the monofilament which is produced by dividing device was decreased. The coefficient of variation of tensile elongation maintained within 15%, and the coefficient of variation of tensile strength maintained within 5%, thus conformed to market demand. The shrinkage of monofilament increase slightly, but it still had a stable trend. The evenness of 20 denier monofilament was worse than 50 denier monofilament.
