Physics-Based Spinning Process Simulation
topic
Spinning process simulation models the fibre mechanics of drafting zone dynamics, yarn twist propagation, traveller balloon mechanics, and fibre-to-fibre interaction using finite element and discrete element methods that solve the equations of motion for fibre assemblies under the forces applied by spinning machine components, enabling prediction of yarn evenness, strength, and hairiness from fibre properties and machine settings without physical spinning trials.
Role
Provides a theoretical framework for understanding and optimising spinning process physics that enables yarn quality prediction from first principles, supporting new product development by identifying the fibre property and machine setting combinations that will achieve target yarn quality specifications and enabling systematic investigation of spinning instability and yarn defect formation mechanisms that cannot be directly observed in the high-speed physical spinning process.
