What is Filament?

In textile, filaments refer to a type of fiber that is produced by spinning from the spinneret during fiber production. Unlike staple fibers, which are short in length, filaments are extremely long and can be indefinite in length. Filaments can be made from a variety of materials such as polyester, nylon, rayon, and silk.

Filament yarns are produced by combining multiple filaments together through a process called twisting. The twisting process adds strength and stability to the yarn, making it suitable for use in various textile applications such as apparel, upholstery, and industrial textiles.

Filament yarns can also be textured or manipulated to create different effects such as a softer hand, more bulk, or a textured appearance. This is achieved through techniques such as air-jet texturing, false twist texturing, and knit-de-knit texturing.

Filament yarns are often preferred over staple fibers because of their strength, durability, and ability to be produced in a range of deniers (thickness). They are also less prone to pilling and can be more resistant to wrinkles and shrinkage. However, they can be more difficult to dye than staple fibers due to their smooth surface and can be more expensive to produce.
