摘　　要：与羊毛常规染色工艺相比,超声波低温染色具有节能降耗、提高产品质量等优点,为此探索超声波技术应用于羊毛纤维低温染色的可行性。研究了50～55℃条件下用活性染料和酸性染料上染羊毛时,超声波作用对上染率及上染速率的影响。结果表明:超声波作用可将该温度条件下的上染率提高约1倍,活性染料对羊毛的上染率有显著提高;并且用活性染料对羊毛染色200 min,或用酸性染料对羊毛染色90 min,2种染料的上染率都超过了90%,可见超声波促染可实现羊毛低温染色,并获得较好的染色效果。Compared with the conventional dyeing process,low temperature ultrasonic dyeing of wool enjoys advantages of energy saving,consumption reduction,improving product quality.The feasibility of ultrasonic technology used in low-temperature dyeing of wool was investigated,and the effects of ultrasound on color yield and dye uptake were studied when ultrasonic dyeing of wool was performed with reactive or acid dyes at 50 ～ 55 ℃.The experiment revealed that ultrasonic action redoubled the color yield under the above temperature condition.The color yield of reactive dyed wool also exhibited significant enhancement.Above 90% color yield can be obtained when ultrasonic dyeing of wool with reactive dyes for 200 min or with acid dyes for 90 min.So,it can be seen that ultrasound promotes low temperature dyeing of wool and good result of dyeing can be achieved.
