Rotor Spinning of Recycled and Blended Fibres
topic
Rotor spinning is particularly tolerant of short fibre, fibre variability, and trash content compared to ring spinning due to the fibre selection and equalisation function of rotor groove accumulation, making it the preferred spinning system for recycled cotton yarns with 40 to 60 percent short fibre content and for blended yarns incorporating recycled polyester where length variability would cause drafting problems in ring spinning.
Role
Enables economically viable yarn production from recycled and blended fibre raw materials with high short fibre content and property variability that would be unsuitable for ring spinning, positioning rotor spinning as the primary yarn manufacturing technology for circular economy recycled content yarns in the growing sustainable textile supply chain segment.
