Semi-worsted spinning process and selection of equipment

In order to better apply the semi-worsted spinning process for production of colored spun yarn,the paper made an analytical comparison of several forms of semi-worsted process,summing up their advantages and disadvantages.The impact of the structure and performance of the machine on the quality of semi-finished product or yarn was investigated,precautions were given for using different production processes and equipments,along with the requirement on individual equipment and management in respect of semi-worsted spinning.Moreover,application of novel spinning technologies to the innovation of the traditional ring spinning frame and development of semi-worsted products was introduced.This paper has provided a reference for rational selection of semi-worsted spinning equipment and further development of the spinning equipments.
