| 摘要: | 本研究以提高現場染色一次成功率為主要目標，在相同配方下，調整小型試樣的染色條件，從與現場染色模式相同的條件下比較後，進行染色條件調整，包括染色機水流噴壓大小、升溫速度以及高溫後的持溫時間。
研究結果顯示，在1℃/min升溫條件下，100%聚酯織物持溫10、20、30分鐘下測得具有相同的上色程度，經檢測在10分鐘織物中的染料已經達到飽和。在3℃/min的升溫條件也保持相同表現，不因升溫快速而產生色差。反觀含Spandex織物在 3℃/min升溫的情況下，因在缸內時間較短，機械張力較小，其色差值表現與1 ℃/min相比有較佳，且色彩深淺也會隨著時間越長而深暗色越淺。
100%聚酯織物在升溫較快、持溫較短的情況下，織物幅寬較現場窄，碼重較輕，色差值△E=0.5-0.75保持在1.0以下，但是Spandex織物因張力此在升溫或持溫狀態下，時間越短者表現會比時間長者其色差值較佳，其布重的碼重也較現場輕，原因在於Spandex織物在前處理工程均有預定型工程，所以在布重變輕的情況下，幅寬都在3-5英吋5%以下，差異不大。
The main goal of this study is to improve the one-time success rate of on-site dyeing. Under the same formula, the mechanical dyeing conditions of small samples are adjusted. After comparing with the same conditions as the on-site dyeing mode, the dyeing conditions are adjusted and the cloth wheel is changed. The speed of water flow, the heating rate, and the holding time at high temperatures. The research results show that under the condition of the heating rate at 1℃, the 100% polyester fabric has the same degree of coloring when the temperature is maintained for 10, 20, and 30 minutes, and the fabric has reached saturation after 10 minutes. The temperature rise condition also maintains the same performance under the heating rate of 3°C, and there is no color difference due to the rapid temperature rising. However, under the condition of 3℃/min temperature rising, due to the short time in the cylinder and the small mechanical tension, the color difference value of the spandex fabric with elasticity is better than that of 1℃/min, and the depth will change with the temperature. The longer shallower. In the case of fast heating and short temperature holding of pure PET fabrics, the fabric width is narrower than the on-site dyeing, the basic weight is lower, and the color difference value △E=0.5–0.75 is kept below 1.0, but the tension of spandex fabrics is here. Under the conditions the heating or maintained temperature, the shorter the time, the better the color difference value and the lighter the code weight is than the one with the longer time. The reason is that the spandex fabric has a pre-processing project setting in the pre-treatment shrunk, so the basis weight changes. In the case of decreased basis, the width is less than 5% of 3-5 inches, and the difference is not obvious. |
