Simulation of the false twist textile yarn texturing process

Abstract

The preliminary modelling of simulation steps required in the development of a generalised CAD (Computer-Aided-Design) package for textile machinery designers is presented. The false twist texturing process (FTTP) is chosen as the starting point, since it is the most important texturing process and it con tains most of the thermomechanical processes used in other tex turing processes. It also has an inherent problem associated with it; at high speed it is very difficult to analyse using conventional analytical techniques. The paper is divided into four sections: an introductory section which describes the false twist texturing process and reviews what modelling work has been done to date; this is followed by a sec tion which describes the simulation techniques employed and the mathematical models used; a results section where the simulation techniques are validated; and a conclusions section.
