What is the name of the blocking cloth on the zipper of the clothes

The blocking cloth on the zipper of clothes is usually called zipper blocking cloth or zipper inner blocking.

Zipper stop fabric is a piece of fabric sewn on the inside of a zipper. Its main function is to prevent the zipper from directly contacting the skin and causing discomfort, while also avoiding the zipper from gripping clothing or skin. This fabric is usually made of the same material as the clothing to ensure overall coordination. In winter clothing, zipper blocking fabric can also play a role in preventing wind and keeping warm. Some sportswear will use breathable mesh fabric as a zipper stopper, balancing protection and breathability requirements.

Some high-end clothing will use a double-layer zipper fabric, with decorative fabrics on the outer layer and skin friendly materials on the inner layer. Special functional clothing such as submachine jackets may have a waterproof coating on their zipper blocking fabric. Children's clothing usually widens the zipper cover area to prevent children from being scratched by the zipper. Some designer brands use zipper fabric as a decorative element, using contrasting colors or special printing treatments.

When wearing it in daily life, pay attention to keeping the zipper guard clean to avoid sweat residue that may cause the fabric to harden. It is recommended to close the zipper when washing clothes to reduce the friction loss between the fabric and the zipper teeth. If burrs are found on the edge of the fabric, they can be trimmed flat with small scissors. For functional clothing, regularly check whether the waterproof coating of the fabric is intact, and if necessary, use professional care agents for maintenance.
