Gel dyeing
| Глоссарий по текстилю и текстильной промышленности |
- Passing a wet-spun fiber that is in the gel state (not yet at full crystallinity or orientation) through a dyebath containing dye with affinity for the fiber. this process provides good accessibility of the dye sites.

Dyeing, английский
- A process of coloring fibers, yarns, or fabrics with either a natural or synthetic dye. a partial list of dyeing methods follows: · pad dyeing – a form of dyeing whereby a dye solution is applied by means of a pad or mangle. · pressure dyeing – dyeing by means of forced circulation of dye through packages of fiber, yarn, or fabric under pressure. · skein dyeing – the dyeing of yarn, fiber, or fabric in the form of skeins, or hanks. · yarn dyeing – the dyeing of yarn before the fabric is woven or knit. e
- A process of coloring fibers, yarns, or fabrics with either natural or synthetic dyes. some of the major dyeing processes are described below:

Dye, английский
- A soluble colorant; as opposed to pigment, which is insoluble.
- A coloring material or compound that imparts color throughout a material by penetration.
- The chemical component added to a penetrant vehicle to provide a characteristic color to the penetrant.

Dye developer, английский
Dye fleck, английский
1. an imperfection in fabric caused by residual undissolved dye. 2. a defect caused by small sections of undrawn thermoplastic yarn that dye deeper that the drawn yarn.
Dye lasers, английский
Lasers based on liquid or solid dyes as gain media
Dye line print, английский
Dye lot, английский
A quantity of textile fiber, yarn, or woven goods dyed in one production run. lot size can vary greatly depending on the mill or finishing plant’s dyeing processes and equipment.
Dye marker, английский
- Brilliant coloring matter which is dropped to spread in or on the water to indicate the position of a person overboard, or a point of action (e.g., where to execute a turn, drop an amphibious craft, etc.).
- A brightly colored chemical that spreads when released into water; normally used to attract attention.
Dye migration, английский
Migration, 1
Dye penetrant, английский
- Penetrant with dye added that makes it readily visible in light.
- See color contrast penetrant. e
Dye penetrant inspection, английский
Dye penetration -, английский
Контроль проникающей краской, цветная дефектоскопия
Dye penetration test / inspection, английский
Dye penetration test method, английский
Метод проверки проницаемости резьбового соединения с помощью краски
Dye range, английский
A broad term referring to the collection of dye and chemical baths, drying equipment, etc., in a continuous-dyeing line. dyes: substances that add color to textiles. they are incorporated into the fiber by chemical reaction, absorption, or dispersion. dyes differ in their resistance to sunlight, perspiration, washing, gas, alkalies, and other agents; their affinity for different fibers; their reaction to cleaning agents and methods; and their solubility and method of application. various classes and types are listed below. [also see colour index (ci).]
Dye sensitized dichromated gelatin, английский
Dye sites, английский
Functional groups within a fiber that provide sites for chemical bonding with the dye molecule. dye sites may be either in the polymer chain or in chemical additives included in the fiber.
Dye stability, английский
Dye stuff; dye, английский
Dye stuffs (mt, pt), английский
A natural or synthetic coloring matter whether soluble or insoluble that is used to color materials usually from a solution or fine dispersion and sometimes with the aid of a chemical (mordant) that serves to fix a dye in or on a substance.
Dye sub, английский
- Limation is a printing process where the color dyes are thermally transferred to the printing media. dye sub printers use the cmyk (cyan, magenta, yellow, black) color format and have either three ribbons (cyan, magenta and yellow) or high-end printers have four cmy plus a black. the paper is run in and out of the printer four times, once for each color and then a fourth time when a protective overcoat is applied. dye sub is continuous tone printing, it prints tiny square dots each of which is denser in the center and lighter on the edges. these dots can be varied from almost no dot at all to an almost completely solid dot. the dyes are transparent so different colored dots can be printed on top of each other to form any one of 16-million colors. this is known as the subtractive color process. dye sub prints rival conventional photographs in both their color gamut and longevity with water and uv resistant qualities. for the sake of accuracy we must state that most printers today that claim to be dye sub type printers are actually dye diffusion. the complete technical name for this process is dye diffusion thermal or d2t printing. to achieve true sublimation printing requires a laser to vaporize the dye material. the common 4x6 dye sub or the bigger ones that do up to 8x10 prints like the olympus p-400 or kodak pro 8500 heat the dye material with a thermal printhead and use pressure rollers to push the ribbon into contact with the paper and then diffusion occurs.
- Dye sublimination is a printing process where the colour dyes are thermally transferred to the printing media. the printers use cmyk colour format. the paper is run in and out of the printer 4 times, once for each colour (c, m and y) and a fourth time when a protective overcoat is applied. dye sub is continuous tone printing, it prints tiny square dots each of which is denser in the centre and lighter on the edges. the dyes are transparent so different coloured dots can be printed on top of each other to form any one of 16 million colours.
Crystallinity, английский
- 1. the state of quality of being crystalline. 2. the extent to which a polymer exists in a lattice structure.
- Degree to which crystals are developed in a rock, especially in
Orientation, английский
- A description of the manner in which the functional pattern is to be viewed.
- The act or process of setting a diamond in the crown of a bit in such an attitude that one of its hard vector planes will come in contact with the rock and be the surface that cuts or abrades it.
- As used in borehole surveying and directional drilling practice, "orientation" refers to the method and procedure used in placing an instrument or tool, such as a deflection wedge, in a drilled hole so that its directional position, bearing, or azimuth is known.
- Placement with respect to the cardinal directions, n, s, e, w; azimuth is the measure of orientation from north.
- In linear polymeric structures, the degree of parallelism of the chain molecules.
- The alignment of an item, such as a control.
- The direction a publication will be printed on a sheet of paper. you can choose either portrait, which is the taller-than-wide orientation, or landscape, which is the wider-than-tall orientation.
- Position of a discontinuity or part or surface in relation to the test surface of the article or ultrasonic beam.
- Angular relationship of a surface, plane, discontinuity, or axis to a reference plane or surface. p
- Angular relationship of a surface, plane, discontinuity or axis to a reference plane or surface.7,21
- Orientation is the process of bringing employees up to speed on organisational policies, job roles and responsibilities
- Orientation is a process that new employees go through to familiarize themselves with the company, people and policies of the business.
- Introducing new hires to the organization and its policies, benefits and culture. training and familiarization with each department are sometimes included.
