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.
Fiber classification in reinforced plastics falls into two classes: (i) short fibers, also known as discontinuous fibers, with a general aspect ratio (defined as the ratio of fiber length to diameter) between 20 and 60, and (ii) long fibers, also known as continuous fibers, the general aspect ratio is between 200 and 500.

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 ...
Jute (/ dʒ u t / JOOT) is a long, rough, shiny bast fibre that can be spun into coarse, strong threads. It is produced from flowering plants in the genus Corchorus, of the mallow family Malvaceae. The primary source of the fiber is Corchorus olitorius, but such fiber is considered inferior to that derived from Corchorus capsularis. [1]
All these fibres will be of great length, often kilometres long. Synthetic fibers are more durable than most natural fibers and will readily pick-up different dyes. Artificial fibres can be processed as long fibres or batched and cut so they can be processed like natural fibre.
Ep = epidermis; C = cortex; BF = bast fibres; P = phloem; X = xylem; Pi = pith. Linen is a bast fiber. Flax fibers vary in length from about 25 to 150 mm (1 to 6 in) and average 12–16 micrometers in diameter. There are two varieties: shorter tow fibers used for coarser fabrics and longer line fibers used for finer fabrics.
Twisting fibres into yarn in the process called spinning can be dated back to the Upper Paleolithic, [18] and yarn spinning was one of the first processes to be industrialized. Spun yarns are produced by placing a series of individual fibres or filaments together to form a continuous assembly of overlapping fibres, usually bound together by twist.
In the 1960s and 1970s, S. G. Stephens performed an experiment where he hybridized a G. barbadense with short coarse fibers and long growing season with a wild form of G. hirsutum that had the same short fiber and long growing season, but the fibers were fine. It seemed reasonable the resulting plant produced fine fibers, but was surprised to ...
