本研究在經濟部能源局節能衫材料技術研發計畫之輔導下，由產(和明紡織股份有限公司)、學(亞東技術學院材料與纖維系)、研(紡織產業綜合研究所)共同研究探討，針對純棉、PET/Cotton、PET/Rayon、PET/Tencel 混紡紗等紡製成強撚雙股紗，探討追撚撚度對於紗種染色性之影響分析，期能了解追撚撚度對染色條件之影響，進而達到製程節能之目標，研究結果顯示，實驗中高支數純棉紗線採用雙股Z 撚追撚(Z+Z→Z)，撚度分別為700 1,000 1,300TPM；聚酯異斷面(十字)纖維低毛羽短纖混紡紗線採用單股追撚(Z→Z)撚度分別為400 700 1,000TPM 實驗結果顯示追撚越高，樣布顏色顏色變深，所測亮度L 值減低，b 值增加偏黃，因此使表觀色強度K/S 值增加。
In this study, the dyeing research of twisting effect of pure cotton yarn and irregular cross-section polyester blend yarn on its yarn properties were discussed and analysis. During the twisting process of cotton yarn, the different twisting conditions of two-folds high-count cotton yarn (Ne100/1 and Ne80/1) were set at 700, 1000, 1300TPM (twisting direction Z+Z→Z). During the twisting process of the irregular cross-section polyester blend yarn (PET/Cotton, PET/Rayon and PET/Tencel), the different twisting conditions of single-fold blend yarn (Ne40/1) were set at 400, 700, 1000TPM (twisting direction Z→Z). From the results,
