The Science Behind Knitting


About 3000 years ago, knitting has been an ancient form of manufacturing, but Elisabetta Matsumoto of the Georgia Institute of Technology in Atlanta noted that knowing how stitch type govern shapes will be important for designing new "tunable" materials.

Matsumoto will be presenting her work on the mathematics rules that govern knitting at the American Physical Society March Meeting in Boston this week. She will also engage in a press conference to explain all that knitting entails.

"By picking a stitch, you are not only choosing the geometry but the elastic properties, and that means you can build in the right mechanical properties for anything from aerospace engineering to tissue scaffolding materials", said Matsumoto.

Matsumoto started knitting as a child and later got interested in mathematics and physics, so she developed a new idea for her occupation. "I realized that there is a lot of mathematics and material science that goes into textiles, but that is taken for granted", said Matsumoto.

Currently, members of the Matsumoto group are now delving through the complicated math which encodes mechanical properties within the interlocking series of slip knots of a material. Although the application of pure mathematical process of knot theory to huge catalog of knitting designs is a tricky process for Matsumoto's graduate student, Shashank Markande.

Besides, the Matsumoto group also focuses on simple stitch designs and curves in knitted lattices.
