Shoe upper

The invention is about making the top part of a shoe, called the upper, from a single piece of knitted fabric. This fabric has two layers, with one layer made from strong synthetic threads. To make the shoe upper more durable, a liquid plastic material is applied to specific areas of the knitted fabric, often by dipping it, and then pressed with heat to create a reinforced coating.

Why it matters: Since 2018, advancements in polymer chemistry and robotic textile manufacturing have made precise, selective coating of knitted fabrics more efficient and potentially sustainable.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateKnitted fabric, polymer coating, heat press
