Production practice of multicomponent colored yarn in air-jet vortex spinning
A low content dyed fiber yarn is developed with small batch of dope-dyed fibers,natural color Modal fibers and seaweed fibers in air-jet vortex spinning.The key process parameter of color spinning is explored,and the mixing uniformity and color mixing effect of fibers in the yarn are analyzed.Aiming at the low strength of seaweed fibers and color difference caused by uneven mixing of small proportion colored fiber,a reasonable process route is designed,and blending ratio of fiber is accurately controlled by weighing system of blending machines.Through the actual testing,the blending ratio of colored spun fibers is accurate,the mixing is uniform,the distribution of colored fibers is well controlled,and the wear resistance is good,achieving the expected yarn quality goals.
