摘要
为探究环保转杯牛仔纱的外观颜色规律,减少牛仔面料生产中存在的环境污染问题,以黑色粘胶条子和白色粘胶条子为原料,在双分梳转杯纺试验机上纺制黑白颜色纤维比例相同、纤维混合次数不同的双分梳转杯纺牛仔纱;详述实验方案及实验用纺纱工艺,利用MATLAB图像处理技术探索纱线外观及结构;验证不同纤维比例、不同织造工艺条件下的牛仔面料风格。指出:双分梳转杯纺牛仔纱外观颜色沿轴向间隔分布且具随机性;当黑白2种颜色的纤维比例均为50/50时,大直径转杯所纺纱线较小直径转杯所纺纱线,黑色纤维更多地分布于表面;在相同转杯周长中白色纤维比例沿纱线轴向呈先减小后增大再减小趋势;双分梳转杯牛仔纱外观颜色分布不匀是由于2种纤维在转杯中混合不均匀引起的。
In order to explore the appearance color law of environmental protection denim rotor yarn and reduce the environmental pollution problems in the production of denim fabric,the double carding denim rotor yarn with the same ratio of black and white color fibers and different mixing times is spun on the double carding spinning machine with black and white viscose slivers as raw materials.The experimental scheme and spinning process used in the experiment are described in detail,and the appearance and structure of yarn is explored using MATLAB image processing technology.The denim fabric styles under different fiber ratio and weaving process conditions are verified.It is pointed out that the appearance color of double carding denim rotor yarn is distributed at intervals along the axial direction and has randomness.When the ratio of black and white fibers is 50/50,more black fibers are distributed on the surface of the large diameter spinning rotor than that of the small diameter spinning rotor.In the same rotor circumference,the proportion of white fiber decreases first,then increases and then decreases along the axis of the yarn.The uneven color distribution of double carding denim rotor yarn is caused by the uneven mixing of the two fibers in the rotor.
