Abstract:

Poor blending uniformity of different component fibers in yarn leads to the decrease in strength, the deterioration of the strength unevenness, and the increase of the chromatic aberration of the fabric. In order to explore the influence of sliver blending process parameters on the blending uniformity, the index of irregularity blending (IBI) was improved to characterize the blending uniformity, and the simulation of the movement of fibers during sliver blending process was analyzed to obtain the distribution regularity of fibers in the mixed sliver. In this study, the influence of different sliver mixing process parameters such as the number of combined slivers, the passages of slivers, arrangement mode, and blending ratio, on the uniformity of yarn sliver mixing was discussed, and the results were verified by experiments. The research results show that the improved IBI can evaluate more accurately the uniformity of blended slivers. The more the number of drawn passages and the number of combined slivers, the more uniform is the blending; the smaller the linear density of feeding sliver, the easier it is to carry out uniform blending. The IBI becomes less while the feeding sliver arranged at intervals and blending ratio of component close to 50∶50. The draft ratio and the distance of roller center do not show obvious effect on the IBI. The simulation results are in good agreement with the tested results.

Key words: sliver blending, process parameter, blending uniformity, index of blending irregularity, simulation
