Texturing
| Строительный глоссарий |
- Офактуривание поверхности, придание поверхности определённой фактуры или текстуры
- The process of crimping, imparting random loops, or otherwise modifying continuous filament yarn to increase cover, resilience, abrasion resistance, warmth, insulation, and moisture absorption or to provide a different surface texture. texturing methods can be placed roughly into six groups. (also see textured yarns.) 1. air jet method: in this method of texturing, yarn is led through the turbulent region of an air jet at a rate faster than it is drawn off on the far side of the jet. in the jet, the yarn structure is opened, loops are formed, and the structure is closed again. some loops are locked inside and others are locked on the surface of the yarn. an example of this method is the taslan process. (also see textured yarns, core-bulked yarn and entangled yarn.) 2. edge crimping method: in this method of texturing, thermoplastic yarns in a heated and stretched condition are drawn over a crimping edge and cooled. edge-crimping machines are used to make agilon yarns. (also see textured yarns, coil yarn.) 3. false-twist method: this continuous method for producing textured yarns utilizes simultaneous twisting, heat-setting, and untwisting. the yarn is taken from the supply package and fed at controlled tension through the heating unit, through a false-twist spindle or over a friction surface that is typically a stack of rotating discs called an aggregate, through a set of take© 2001, celanese acetate llc up rolls, and onto a take-up package. the twist is set into the yarn by the action of the heater tube and subsequently is removed above the spindle or aggregate resulting in a group of filaments with the potential to form helical springs. much higher processing speeds can be achieved with friction false twisting than with conventional spindle false twisting. both stretch and bulked yarns can be produced by either process. examples of false-twist textured yarns are superloft®, flufflon®, and helanca®. (also see textured yarns, coil yarn.) 4. gear crimping method: in this texturing method, yarn is fed through the meshing teeth of two gears. the yarn takes on the shape of the gear teeth. (also see textured yarns, crinkle yarn.) 5. knit-de-knit method: in this method of texturing, the yarn is knit into a 2-inch diameter hose-leg, heat-set in an autoclave, and then unraveled and wound onto a final package. this texturing method produces a crinkle yarn. (also see textured yarns, crinkle yarn.) 6. stuffer box method: the crimping unit consists of two feed rolls and a brass tube stuffer box. by compressing the yarn into the heated stuffer box, the individual filaments are caused to fold or bend at a sharp angle, while being simultaneously set by a heating device. (also see textured yarns, crinkle yarn.)

Resilience, английский
- The property whereby a strained body gives up its stored energy on the removal of the deforming force.
- The ability of a body that has been subjected to an external force to recover its size and shape, following deformation.
- Способность быстро восстанавливать физические и душевные силы
- The amount of energy per unit volume released upon unloading.
- The capacity of a metal, by virtue of high yield strength and low elastic modulus, to exhibit considerable elastic recovery upon release of load.
- The ability to recover in a speedy fashion from difficulties or challenges, often a quality that coaches or mentors help individuals develop.
Resistance, английский
- Property of a conductor that opposed the current flow produced by a given difference of potential. the ohm is the practical unit of resistance.
- Уровень сопротивления - уровень цен, при котором активные продажи могут приостановить или развернуть тенденцию к повышению;
- 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.
- An effective upper bound on prices achieved because of many willing sellers at that price level.
- Capacity of a component, or cross section of a component of a structure to
- The opposition to the flow of an electrical current through a conductor or circuit that does not include inductive or capacitive elements. it can be expressed as the ratio of the applied voltage to the current.
- Resistance is the opposition to the flow of an electrical current through a conductor. its unit is the ohm.
Insulation, английский
- Material which offers extremely high resistance to the passage of current.
- Any material high in resistance to heat transmission that, when placed in the walls, ceiling, or floors of a structure, and will reduce the rate of heat flow.
- Any material that slows down the transfer of heat.
- Any material that reduces the speed of heat transfer
- Изоляция
- A material having high resistance to the flow of electric current. often called a dielectric.
- Изоляция; материал, используемый для изоляции холодильника (морозильника, термоконтейнера и т.п.) integrated disease surveillance (ids)
- Изоляция; материал, используемый для изоляции холодильника (морозильника, термоконтейнера и т.п.)
- Изоляция; изоляционный материал
- A material used to prevent the flow of heat into or out of a building. often consists of ‘batts’ placed in the ceilings and walls, but can also be metal foil or ‘loose fill’ materials, such as recycled paper fluff.
- A material used to prevent the flow of electricity. normally used on electrical wires to prevent electric shock. typical materials used include plastics such as pvc and polypropylene, as well as ceramics and minerals such as mica.
