The Dynamic Study of the Weft Insertion of Air Jet Weaving MachinesKeywords: air jet weft insertion , confusor air guides , maintained air jet , fiction force , skin friction coefficient , friction force measurement , momentum , multifilament weft yarn Abstract: The application of the air jet loom is widespread in the textile industry because ofits high productivity, convenient controllability, high filling insertion rate, low noise andlow vibration levels. Air stream in confusor guides can be classified into two types. A weftyarn ejected with high speed air flow is given the drag force caused by friction between theweft yarn and the air flow. In this article we show the study of the dynamics of the type Pair jet weaving machines and the definition of the skin friction coefficient for multifilamentweft. We have given a calculation procedure for the dynamic description of the insertionprocess of weaving machines marked P.
