The use of visualisation and simulation techniques to model the splicing process

Abstract

Pneumatic yarn splicing is a well‐established technique for joining two yarn ends together by means of a blast of compressed air in a device known as a splicing chamber. Earlier research done in 2007 by Webb and colleagues optimised external splicer parameters, such as air pressure and duration, for maximum splice strength, using experimental data only. Indirect observations such as air pressure offer no insight into the theory behind the splicing process. Observing the splice formation with the naked eye is difficult because of the short duration and sealed environment of the splicing process. This paper reports on the application of visualisation and simulation techniques to the theoretical study of the splice formation.
