Abstract

Abstract : Pneumatic splicing is the widely used method to join the yarn without a knot using compressed air. The function of the pneumatic splicer is to untwist and retwist the overlapped yarn ends. As the compressed air is playing vital role in pneumatic splicing, to study the effect of air flow pattern and velocity of the compressed air applied on the yarn body is equally important when compared with the study of splicer related parameters and yarn related parameters for better splicing performance. Computational fluid dynamics (CFD) is the right tool to analyse the airflow pattern and the behaviour of yarn body under the influence of compressed air. Therefore, Solidworks CFD software was used to study the compressed air flow pattern and simulation of the behaviour of yarn body when it comes to contact with high pressure air. The airflow pattern during untwisting and retwisting has been studied in detail and given in this study. In addition to that, simulation of the yarn body during untwisting is also studied. Also the airflow equilibrium during retwisting has been studied.
