Pulling on a knitted scarf can stretch it to twice its length, even though the thread it’s knitted from hardly elongates. Knitting is a timeworn craft, at least a thousand years old, but no satisfactory account of the mechanics of its stretchiness exists.
New theoretical work describes how individual stitches in a knitted fabric respond to tension. The model correctly predicts how a nylon knit stretches, and it could be helpful in designing “smart materials” that can spontaneously fold into a specific shape. (...)
