Polyester Rubber Covered Yarn Natural Rubber Thread Yarn for Socks

Rubber yarn, also known as elastic yarn, combines covered yarn with materials such as latex or spandex.

One of the main uses of rubber yarn is in the cuffs of socks. Rubber yarn provides the necessary elasticity to ensure that socks remain snug and comfortable, preventing them from sliding down during wear. This is especially important for activities that involve a lot of movement, such as running, hiking, or daily commuting.
