Seed fiber

Fibers (see Fibers, survey) used in textile production can have a wide variety of origins plants, ie, ceUulosic fibers (see Fibers, cellulose esters) animals, ie, protein fibers (see Wool) and, in the twentieth century, synthetic polymers. Depending on the part of the plant, the ceUulosic fibers can be classified as seed fibers, eg, cotton (qv), kapok bast fibers, eg, linen from flax, hemp, jute and leaf fibers, eg, agave. Protein fibers include wool and hair fibers from a large variety of mammals, eg, sheep, goats, camels, rabbits, etc, and the cocoon material of insect larvae (sUk). Real sUk is derived from the cocoon of the silkworm, Bombjx mori and for a long time was only produced in China, from which it was traded widely as a highly valuable material.

Antigalactogogue effect. Dried kernel, administered to cows at a concentration of 50% of diet, was inactive . Antihypercholesterolemic activity. Seeds, administered orally to 20 adults with mild hypercholesterolemia at a dose of 5.1 g/day for 40 days, reduced LDL cholesterol by 8% and total cholesterol by 6% . Dried seed fiber, in the ration of Syrian hamster at a dose of 7.5% of diet, was active . Dried seed fiber, administered orally to adults at a dose of 10.2 g/day, was active . Dried seed fiber, administered orally to 50 healthy children 2 to 11 years of age at a dose of 6.4 g/ day for 12 weeks, was active The hydro-phobic colloid of the dried seed, administered in the ration of sea quails at a dose of 10% of diet, was active vs diet-inducing hypercholesterolemia . The seed hull, administered in the ration of genetically diabetic mice at a dose of 2.5% of diet for 18 weeks, was active.

There are many kinds of natnral fibers, snch as bast fibers (flax, hemp, jute, kenaf, ramie, nettle, and mesta), leaf fibers (sisal, heneqnen, pineapple, abaca, oil palm, and screw pine), seed fibers (cotton), frnit fibers (coconnt hnsk, or coir), and stalk fibers (straw of varions kinds). They are not nsed for commercial WPG, primarily on economical reasons (except maybe Procell, see Table 1.1). Most of these fibers have fonnd applications in established indnstries, snch as textile indnstry (cotton, flax, jnte, ramie, hemp, and sisal) and paper indnstry (straw).

Natural fibers can be classified as seed fibers (such as cotton), bast fibers (like flax, hemp, jute, kenaf, ramie), hard fibers (like sisal), fi-uit fibers (like coir), and wood fibers. The chemical composition and dimensions of some common agro-fibers are presented in Table 5.21. The origin of wood fibers can be sawmill chips, sawdust, wood flour or powder, cutter shavings, pulp or wood residues. As binders for these fibers, both thermosetting (like phenolic, epoxy, polyester) resins and thermosetting matrices [such as polyethylene (LDPE, HDPE), polypropylene (PP), poly(vinyl chloride) (PVC), polystyrene (PS)j can be used. Thermoplastic composites are, however, less expensive to process than thermosetting composites, in addition to their ability to be manufactured into complex shapes. 

Commercially useful fibers come primarily from the leaves or stems or seed coverings of specific plants. The functional role of fibers in the plant clearly need not be as structural components. Fibers such as cotton and coir serve to protect the seed or fruit from mechanical and perhaps pest or microbial damage. Cotton and other similarly attached seed fibers are also expected, by nature, to play an extremely important role in plant propagation the low mass-to-volume ratio of the seed-fiber ensemble makes it possible for the aerodynamic or buoyancy forces to transport it over large distances. 

A widely accepted classification of fibers is based on their location in the plant. Accordingly, the three principal categories are seed fibers, bast fibers, and leaf fibers. Fibers that do not belong to one of these three categories are classified as miscellaneous fibers.
