Abstract:	本研究是以聚酯原絲為原料，製作出不同撚度搭配的合股索，經施加不同張力下及六段熱處理後，探討不同撚度搭配、施加張力的大小，對於撚縮率、熱縮率、拉伸強力之影響。由實驗結果得知，撚縮率均隨著撚度提高而上升。熱縮率會隨著撚度提高而下降，當樣本在125℃、150℃、175℃的溫度製程下，依撚度大小對應施加1-1.5kg張力，熱縮率可維持在0%，至於超過200℃以上的溫度製程則必須施加超過1.5kg的張力來降低熱縮。以本實驗在第一次合股為2，第二次合股為1，在0kg張力下行熱處理後，有最高拉伸強力64.26kgf，而在第一次合股為4，第二次合股為3，在0.5kg、1kg、1.5kg張力下行熱處理後，分別有最高拉伸強力67.53kgf、65.08kgf、65.61kgf。 In this study, we used the polyester filament to produce a variety of filament ply yarns with the different of twist number. By using the tensile, through the six-level heat treatment system. We analysis the properties on strength, twist shrinkage, heat shrinkage of polyester ply yarn. It is found the twist shrinkage increase by twist number, but the heat shrinkage decrease. According with the twist level, the rate of heat shrinkage keep in 0% to applied 1-1.5kg force at the 125℃, 150℃, 175℃. The best to applied more than 1.5kg force at the 200℃, 225℃, 250℃.In 0kg force, the best tensile strength is 64.26kgf in 2 of twist number in first twisting and 1 of twist number in second twisting. In 0.5kg, 1kg, 1.5kg force, the best tensile strength are 67.53kgf, 65.08kgf, 65.61kgf in 4 of twist number in first twisting and 3 of twist number in second twisting.
