A staple fiber is a textile fiber of discrete length. The opposite is a filament fiber, which comes in continuous lengths. Staple length is a characteristic fiber length of a sample of staple fibers. It is an essential criterion in yarn spinning, and aids in cohesion and twisting. Compared to synthetic fibers, natural fibers tend to have ...
Rayon was produced only as a filament fiber until the 1930s, when methods were developed to utilize "broken waste rayon" as staple fiber. [citation needed] Manufacturers' search for a less environmentally-harmful process for making Rayon led to the development of the lyocell method for producing Rayon. [20]
It is manufactured as a filament, then cut into short staple lengths similar to wool hairs, and spun into yarn. Modacrylic is a modified acrylic fiber that contains at least 35% and at most 85% acrylonitrile. Vinylidene chloride or vinyl bromide used in modacrylic give the fiber flame retardant properties. End-uses of modacrylic include faux ...
Lyocell is a semi-synthetic fiber used to make textiles for clothing and other purposes. [1] It is a form of regenerated cellulose made by dissolving pulp and dry jet-wet spinning . Unlike rayon made by the more common viscose processes, Lyocell production does not use carbon disulfide , [ 2 ] [ 3 ] which is toxic to workers and the environment.
Textile fibres or textile fibers (see spelling differences) can be created from many natural sources (animal hair or fur, cocoons as with silk worm cocoons), as well as semisynthetic methods that use naturally occurring polymers, and synthetic methods that use polymer-based materials, and even minerals such as metals to make foils and wires.
The first artificial fiber, commercially promoted as artificial silk, became known as viscose around 1894, and finally rayon in 1924. A similar product known as cellulose acetate was discovered in 1865. Rayon and acetate are both artificial fibers, but not fully synthetic, being a product of a chemically digested feedstock comprising natural wood.
Modacrylics are creamy or white and are produced in tow and staple form. If looked at in cross section views they have an irregular shape. Modacrylic fibers are also produced in many different lengths, crimp levels, deniers and they can have various shrinkage potentials. Current modacrylic fiber producers include Kaneka Corporation in Japan. [4]
Many processes are needed before a clean even staple is obtained. With the exception of silk, each of these fibres is short, only centimetres in length, and each has a rough surface that enables it to bond with similar staples. [3] Artificial fibres can be processed as long fibres or batched and cut so they can be processed like a natural fibre.
