What is the purpose of a Flange or Lip in textile applications?

The purpose of a Flange or Lip in textile applications primarily revolves around its function in facilitating the insertion of one fabric item into another. This detail is particularly useful in various applications such as cushions, pillows, and upholstered furniture, where the flange creates a structured edge that allows the fabric components to be interlocked or layered together smoothly. This design feature can also enhance the overall fit and aesthetic by offering a clean finish, ensuring that the fabric can be secured without fraying or losing shape at the edges.

While structural support, decorative aspects, and material strengthening can be important considerations in the design of textiles, the defining characteristic of a flange is its role in enabling the integration of fabrics in a way that enhances functionality and appearance.
