- A unit of matter, either natural or manufactured, that forms the basic element of fabrics and other textile structures. a fiber is characterized by having a length at least 100 times its diameter or width. the term refers to units that can be spun into a yarn or made into a fabric by various methods including weaving, knitting, braiding, felting, and twisting. the essential requirements for fibers to be spun into yarn include a length of at least 5 millimeters, flexibility, cohesiveness, and sufficient strength. other important properties include elasticity, fineness, uniformity, durability, and luster. (also see manufactured fiber and natural fiber.)

- An optical fiber in which the core refractive index varies periodically, causing bragg scatting at wavelengths selected by the period and refractive index. a fiber bragg grating reflects the selected wavelength and transmits others.

- Сопротивление (параметр)
- Сопротивление
- Сопротивление, т. е. уровень цен, при котором активные продажи могут приостановить или развернуть тенденцию к повышению.
- 1. the ability of a person not to get a disease 2. the ability of bacteria or a virus to remain unaffected by a drug the bacteria have developed a resistance to certain antibiotics. 3. opposition to a force
- Resistencia
- Устойчивость; резистентность resource for child health (reach)
- Устойчивость; резистентность
- The property of opposing movement, for example [1] electrical conductors offer resistance to the flow of electricity and dissipate some of its energy, usually as heat. [2] water resists the movement of vessels or other objects by parasitic drag, consuming some of the power available to drive the vessel forward.
- Imperviousness of the coating to mechanical, chemical, physical or weather influences
- Capacity of a member or component, or a cross-section of a member or component of a structure, to withstand actions without mechanical failure e.g. bending resistance, buckling resistance, tension resistance
- A material’s ability to restrict the flow of electrical current through itself. measured in ohms.
- The opposition of a circuit to the flow of current . resistance is measured in ohms, and can be calculated by dividing the voltage by current.
- The ability to impede (resist) the flow of electric current. with the exception of superconductors, all substances have a greater or lesser degree of resistance. substances with very low resistance, such as metals, conduct electricity well and are called conductors. substances with very high resistance, such as glass and rubber, conduct electricity poorly and are called nonconductors or insulators.

Polyethylene fiber, английский
- A manufactured fiber made of polymerized polyethylene units, often in monofilament form as well as in filament form. the fibers have low specific gravity, very low retention of moisture, the same tensile weight wet or dry, are resistant to mildew and insects.

Nylon fiber, английский
- A manufactured fiber in which the fiber-forming substance is a long chain synthetic polyamide having recurring amide groups (-nh-co-) as an integral part of the polymer chain.
- A manufactured fiber in which the fiber forming substance is any long chain synthetic polyamide having recurring amide groups (-nh-co-) as an integral part of the polymer chain (ftc definition). the two principal nylons are nylon 66, which is polyhexamethylenedianime adipamide, and nylon 6, which is polycaprolactam. nylon 66 is so designated because each of the raw materials, hexamethylenediamine and adipic acid, contains six carbon atoms. in the manufacture of nylon 66 fiber, these materials are combined, and the resultant monomer is then polymerized. after polymerization, the material is hardened into a translucent ivory-white solid that is cut or broken into fine chips, flakes, or pellets. this material is melted and extruded through a spinneret while in the molten state to form filaments that solidify quickly as they reach the cooler air. the filaments are then drawn, or stretched, to orient the long molecules from a random arrangement to an orderly one in the direction of the fiber axis. this drawing process gives elasticity and strength to the filaments. nylon 6 was developed in germany where the raw material, caprolactam, had been known for some time. it was not until nylon 66 was developed in the united states that work was initiated to convert caprolactam into a fiber. the process for nylon 6 is simpler in some respects than that for nylon 66. although nylon 6 has a much lower melting point than nylon 66 (a disadvantage for a few applications), it has superior resistance to light degradation and better dyeability, elastic recovery, fatigue resistance, and thermal stability.
