摘要

本研究旨在製造不同於一般聚酯加工絲的仿短纖絲。我們以聚酯加工絲為芯絲，半延伸絲為包繞絲，因芯絲與包繞絲的物性差異，長絲仿短纖紗織物經乾、熱作用後，由於兩種原料的收縮率不同而造成織物結構變化，可產生與一般聚酯加工絲織物有別的質感。實驗過程中我們以轉筒式加撚包繞機撚製長絲仿短纖絲，分別改變製程的轉筒速度、撚係數、砂輪組號數和芯絲細度，討論以上的實驗參數對仿短纖絲的強度和伸度、毛羽數等影響。本實驗所得的仿短纖絲物性評估可得下列具體結果：砂輪號數小者，仿短纖絲毛羽個數較多，但強度和伸度表現較不佳。撚係數的增加會使得毛羽數降低，但與強度和伸度間無明顯關係。轉筒速度越高其強度和伸度較大，但毛羽數降低。整体評估下，在撚係數1.4左右，轉筒速度800rpm左右，與(60#+120#)砂輪組的條件所產生的仿短纖絲有較佳的強伸度與仿製效果。

The purpose of this research was to produce the spun-like continuous filament yam which was different to the normal textured yam. We used textured yam as core yam and partially oriented yam as wrapping yam. Owing to the different shrinkage in two materials, spun-like yam will be shrunken after wet-heat treatment, which altered the handle of fabrics. During experiment, we changed the speed of rotor twister, twist multiplier, grinding wheels number and counts. Moreover, we dealt with the effect of parameter on the tenacity, elongation, and hairiness number. On analysis, it gave the following results. Small grinding wheels number cause larger fluff number and well performance in fluff evenness but on he other hand the tenacity and elongation is low. Twist multiplier has nothing to do with tenacity, elongation and fluff evenness. But there is a decrease on the fluff number when twist multiplier increased. With the rotor speed Increasing, the tenacity and elongation get more and more increased, that is to say, high speed has better tenacity and elongation. However, the higher rotor speed may cause low hairiness number. In conclusion, under twist multiplier l.4, rotor speed 8000 rpm and (60#+ 120#)grinding wheels conditions, spun-like yam might be obtained well performance in physical properties and imitation effect.
