TPU tape for socks

In no-show socks, TPU elastic tapes are primarily used at the heel area to prevent slipping while remaining discreet. These elastic tapes are typically transparent or semi-transparent and are sewn into the inner edge of the sock opening, making them hardly visible when worn. They do not irritate the skin and help the sock stay securely in place.

Depending on the type of sock, different elastic tapes are used. Socks designed to be completely invisible often use fully transparent TPU tapes that are 0.2mm-0.3mm thick. It is thin and barely noticeable, ideal for pairing with low-cut shoes. If greater elasticity is needed, a textured or matte-finish TPU mobilon tape is preferred, as it offers better stretch and keeps the sock from slipping during movement.

The width of the elastic tape is usually range from 6mm to 10mm, a size that balances effectiveness and comfort. During manufacturing, specialized sewing machines stitch it in a wave-shaped pattern between two layers of fabric, ensuring even distribution of tension and preventing discomfort or digging into the skin.

This type of elastic tape is highly durable. It can withstand frequent washing without significant wear and retains its elasticity well over time. Sweat and regular machine washing have little impact on its performance.

In summary, the small transparent tape at the heel of no-show socks, though often overlooked, plays a key role in enhancing comfort and fit, making it a highly practical and thoughtful design detail.
