摘　　要：针对生产混色纱时纤维混合工序复杂,车间管理难度较大的现状,提出了双通道环锭数码纺的新方法,可实现纺纱和纤维混合的同步进行。研究了通过数字化牵伸调控纤维混纺比生产混色纱的成纱机制。设计了以10%为梯度的混色纺纱方案,制备了5种纯色纱和90种混色纱,运用Photoshop软件预先对混色纱的色彩效果进行了模拟仿真。对混色纱的结构、条干及拉伸力学性能进行测试分析。结果表明:利用双通道环锭数码细纱机通过调控色纤维混纺比可制备色彩变化的混色纱;由于牵伸、加捻方式的原因,2种色纤维中随着其中任一种纤维所占比例的提高,混色纱的断裂强度呈现先增高后降低的趋势,2种色纤维比例接近或相等时,混色纱的断裂强度高于纯色纱。In view of complicated fiber blending process and hard workshop management,the proposed digital ring spinning method could realize the synchronization of the spinning and the fiber blending.The mechanism of digitizing drafting to control the blending ratio of yarn to produce melange yarn was studied.The fiber blending scheme with 10%gradient was designed and 5 kinds of solid color yarn and 90 kinds of melange yarn were spun,and the color of melange yarn was simulated by Photoshop software.The structure,evenness and tensile mechanical properties of the the yarn were tested and analyzed.The results show that the spinning and the fiber blending can achieve synchronization in one step by controlling the blending ratio of different colored fibers through a double channel digital ring spinning machine.Because of the mechanism of the double channel digital ring spinning draft and twisting,with the increase of any proportion of the colored fiber,the fracture strength of melange yarn shows the trend of increase first and then decrease.When the ratios of the two colored fibers are close to each other,the yarn has the fracture strength higher than solid color yarn.
