Filament (textile fiber)

Structures of multifilament and monofilament fabrics, enlarged

In textile terminology, filament is the international name for fibers of practically unlimited length. Filaments are also known as continuous fibers . A fiber with a length of at least 1000 m is defined as a filament.

The filaments include:

all man-made fibers with the exception of products that are cut or torn to a staple length ,
Nature silk .

In German usage, however, natural silk is not referred to as a filament.

Until the 1960s, in the FRG and in the GDR even until their end, the filament produced in the manufacture of man-made fibers was also called elementary thread (see thread ).

Single filament / multifilament

Endless man-made fibers are usually supplied as a bundle (multifilament or multifilament ) made of several individual filaments for textile processing . Each bundle usually contains as many threads as the number of openings in the production nozzle through which they were formed. The single filament is also called a capillary thread .

Filaments for certain purposes ( fishing lines , brush bristles , synthetic hair, etc.) are spun from single-hole nozzles and are used as (relatively thick) individual fibers, called monofilaments .

Filament production doubled from 2005 to 2015 and reached around 44 million tons, most of which were polyester and polyamide fibers .

Filament yarns

As a filament or continuous filament yarns or multifilament 60900 all manufactured from filaments in accordance with DIN yarns designated. They can be smooth or textured . These include a. the BCF ( Bulked Continuous Filament ) yarns, bulked spinneret -dyed filaments; these are mainly used in carpet manufacture by tufting .
