Biological material may refer to:Tissue (biology), or just tissue
Biomass, living or dead biological matter, often plants grown as fuel
Biomass (ecology), the total mass of living biological matter
Biomaterials
Biocompatible materials and bioapplicable materials
Biomolecule, a chemical compound that naturally occurs in living organisms
Biotic material, from living things
Bio-based material, a processed biotic material
Cellular component, material and substances of which cells (and thus living organisms) are composed
Organic matter, derived from living things or containing carbon
Viable material, capable of living, developing, or germinating under favorable conditions. (see: viability selection)
Bodily fluid.
Synthetic fibers are the result of extensive research by scientists to improve upon naturally occurring animal and plant fibers. In general, synthetic fibers are created by forcing, usually through extrusion, fiber forming materials through holes (called spinnerets) into the air, forming a thread. Before synthetic fibers were developed, artificially manufactured fibers were made from cellulose, which comes from plants. These fibers are called cellulose fibers.
Synthetic fibers account for about half of all fiber usage, with applications in every field of fiber and textile technology. Although many classes of fiber based on synthetic polymers have been evaluated as potentially valuable commercial products, four of them - nylon, polyester, acrylic and polyolefin - dominate the market. These four account for approximately 98 per cent by volume of synthetic fiber production, with polyester alone accounting for around 60 per cent.
Nylon, the first synthetic fiber, made its debut in the United States as a replacement for silk, just in time for World War II rationing. Its novel use as a material for women's stockings overshadowed more practical uses, such as a replacement for the silk in parachutes and other military uses.........
