NYLON SCY 40D+75D

SCY is a type of yarn that consists of a core yarn surrounded or covered by another yarn. The covering yarn is wound around the core yarn through a mechanical process, such as twisting or wrapping. This covering provides additional properties to the yarn, such as increased strength, durability, texture, or decorative effects. The core yarn is typically a basic yarn that provides the foundational structure, while the covering yarn can be of a different material, color, or texture, adding a layer of complexity and versatility to the final product. The mechanical covering process can be achieved through various techniques, such as air-jet covering, ring twisting, or friction spinning.
