Synthetic fibers or synthetic fibres (in British English; see spelling differences) are fibers made by humans through chemical synthesis, as opposed to natural fibers that are directly derived from living organisms, such as plants (like cotton) or fur from animals.
Fiber (also spelled fibre in British English; from Latin: fibra) [1] is a natural or artificial substance that is significantly longer than it is wide. [2] Fibers are often used in the manufacture of other materials. The strongest engineering materials often incorporate fibers, for example carbon fiber and ultra-high-molecular-weight polyethylene.
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 ...
The chemical composition of common natural fibers are shown below; [6] these vary depending on whether the fiber is a bast fiber (obtained from the bark), a core fiber (obtained from the wood), or a leaf fiber (obtained from the leaves).
Depending on the chemical composition of the glassy fiber and the time and temperature to which the materials are exposed, different stable crystalline phases may form. In after-use high-temperature mineral wool crystalline silica crystals are embedded in a matrix composed of other crystals and glasses.
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.
Rags made of microfiber must only be washed with regular laundry detergent, not oily, self-softening, soap-based detergents. Fabric softener must not be used; [7] the oils and cationic surfactants in the softener and self-softening detergents will clog up the fibers and make them less absorbent until the oils are washed out. Hot temperatures ...
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.
