Filament yarn consists of filament fibres (very long continuous fibres) either twisted together or only grouped together. Thicker monofilaments are typically used for industrial purposes rather than fabric production or decoration. Silk is a natural filament, and synthetic filament yarns are used to produce silk-like effects.
The product is continuous strands. These are called filament yarns. Examples of synthetic fibers are polyester, polyamide, and acrylic. Silk is the only natural fiber obtained as a filament. [22] [5] [6] If filament fiber is cut into discrete lengths, it becomes staple fiber.
In the artificial fibre and composites industries, a tow is an untwisted bundle of continuous filaments, in particular of acrylic, carbon fibres, or viscose rayon. Tows are designated either by their total tex (mass in grams per 1000 m length) [3] or by the number of fibres they contain. [4] [5] For example, a 12K tow contains 12,000 fibres. [6 ...
In German the word is Luftex. The process is simply feeding a bundle of continuous filament yarns into a small jet nozzle with various amounts of slack (overfeed). High-pressure air ( > 100 PSI ) creates suction and a turbulent airstream which tangles any slack into a yarn with a similar hand as a spun yarn. It is the turbulent airflow that ...
The fibers making up a yarn may be continuous filament fibers such as silk and many synthetics, or they may be staples (fibers of an average length, typically a few inches); naturally filament fibers are sometimes cut up into staples before spinning. The strength of the spun yarn against breaking is determined by the amount of twist, the length ...
filament A filament is a fine, thinly spun thread, fiber, or wire. filling See Weft finishing Finishing refers to any process performed on yarn or fabric after weaving to improve the look, performance, or "hand" (feel) of the finished textile.

Ban-Lon (sometimes spelled BanLon or Banlon) is a trademarked, multistrand, continuous-filament synthetic yarn used in the retail clothing industry. It was created in 1954 by Joseph Bancroft & Sons Company, by applying a process for crimping yarn to nylon in order to achieve greater bulk than ordinary yarns.
This step is a detangler, prior to carding and spinning into yarn. At this stage, the dried, finished fibers are in a form called tow, a large, untwisted bundle of continuous lengths of filament. The bundles of tow are taken to a crimper, a machine that compresses the fiber, giving it texture and bulk.
