Polypropylene fiber
| Глоссарий терминов в легкой промышленности и текстиле |
- A manufactured olefin fiber made from polymers or copolymers of polypropylene. this is a tough fiber with a tenacity of 3.5 to 4.5 grams/denier and a melting point of 165° c. it is so light in weight that it floats and is highly resistant to mechanical abuse and chemical attack.
- A manufactured, olefin fiber made from polymers or copolymers of propylene. polypropylene fiber is produced by melt spinning the molten polymer, followed by stretching to orient the fiber molecules.

Fiber, английский
- General term for any long, narrow cell of wood.
- Волокно, нить
- A single optical transmission element characterized by a core, a cladding, and a coating. two common structures, single-mode (with a step-index profile) or multimode (with a graded-index profile) are used for fiber optic communication systems. different variations are made depending on the attenuation, bandwidth, dispersion, wavelengths, and mechanical requirements
- Us same as fibre
- Волокно
- [1] any substance (such as cotton, flax, or hemp) that can be separated into threads and twisted or braided together (i.e., to make rope). [2] the word has other meanings in anatomy (nerve, muscle, or connective tissue), botany (slender, threadlike root), nutrition (bulk, dietary fiber, roughage), optics (optical fiber), and as a character trait (moral fiber).
- Волокно; фибра о ~ in
- Term for a unit of any natural or synthetic textile raw material used for manufacturing fabric.
- Термин для единицы любого натурального или синтетического текстильного сырья, используемого для производства ткани.
- 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.)
Fiber, шведский
Fiber (fibre), английский
- The characteristic of wrought metal that indicates directional properties and is revealed by the etching of a longitudinal section or is manifested by the fibrous or woody appearance of a fracture. it is caused chiefly by the extension of the constituents of the metal, both metallic and nonmetallic, in the direction of working.
- The pattern of preferred orientation of metal crystals after a given deformation process, usually wiredrawing.
Fiber -, английский
Опалубка из древесно-волокни- стых материалов (листов, плит)
Fiber amplifier, английский
- Most common are the erbium doped fiber amplifiers (edfas), semiconductor optical amplifiers (soas), and raman amplifiers, which are used to increase signal gain without electrical conversion
- An optical fiber doped to amplify light from an external source. the most important type is the erbium-doped fiber amplifier.
Fiber amplifiers, английский

Fiber architecture, английский
The spatial arrangement of fibers in the preform. each architecture has a definite repeating unit.
Fiber axis, английский
Ось симметрии волокнистой текстуры, продольная ось проволоки
Fiber bandwidth, английский
The lowest frequency at which the magnitude of the fiber transfer function decreases to a specified fraction of the zero frequency value. often, the specified value is one-half the optical power at zero frequency.
Fiber bed filter, английский
Fiber bonding (binding), английский
Fiber bragg grating (fbg), английский
- A piece of photo-refractive fiber that is exposed to highintensity uv interference patterns, causing it to reflect a specific wavelength while being transparent to all other wavelengths. used as a filter in wdm systems
- 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.
Fiber bragg gratings, английский
Reflective structures in the core of an optical fiber with a periodic or aperiodic perturbation of the effective refractive index
Fiber cables, английский
Cables containing one or several optical fibers
Fiber channel arbitrated loop, английский

Polypropylene, английский
- A thermoplastic polymer of propylene.
- Полипропилен - прочный пластиковый материал, необходимый в массовом производстве "дутых" досок.
- A plastic polymer of propylene; a tough material having good resistance to heat and chemical action.
- Полипропилен
- A manufactured fiber made from polymers that is strong and resilient, relatively inert, and does not absorb water or dirt. see olefin.
- Polypropylene is a synthetic resin that is strong and can be used in the making of furniture as a highly durable and often glossy protective coating.
Mechanical, английский
Stretching, английский

Moisture regain, английский
- A measure of the increase in weight due to the adsorption of water by a fiber vs. its initial dry weight. usually expressed as %.
- The percentage of moisture in a textile material brought into equilibrium with a standard atmosphere after partial drying, calculated as a percentage of the moisture-free weight. (also see standard moisture regain.)
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.
- A manufactured fiber made of polyethylene, often in monofilament form as well as continuous filament yarns and staple. ethylene is polymerized at high pressures and the resulting polymer is melt spun and cold drawn. it may also be dry-spun from xylene solution.
