Knitted fabric is a meta-material created from a single thread, with the particular property of deforming through discontinuous slips at the yarn–yarn contact points. These discrete events can propagate to neighboring stitches, resulting in an avalanche phenomenon. Intermittent in time and scale-invariant, they appear both in the system’s force signal and in the deformation field of the stitches. A systematic study of these events allows us to define the limits within which knitted fabric can be considered an earthquake-like system, thereby justifying the interest in attempting to forecast, if not predict, such knitquake events. As in most analogous models, the peculiar statistics of the corresponding time series severely hinder this endeavor, making the accurate forecasting of extreme events particularly challenging. We therefore introduce machine learning techniques that allow us to investigate their predictability.
