Classification according to application

1 Acid. Acid dyes are chiefly used for dyeing wool and PA. They are anionic and are apphed from an acid dyebath. [Pg.72]

2 Mordant. This class is now restricted to that group of special wool dyes, the dyeings from which are treated with aqueous bichromate in order to improve wet fastness. This treatment may be apphed to the fabric before dyeing, during the dyeing process or afterwards. Application after dyeing or after chrome process is the method most widely used. [Pg.72]

3 Basic. The basic dyes are cationic dyes, often brilliant in shade and of very high tinctorial strength, but having inferior fastness properties on cotton, which requires to be tannin-mordanted before it can be dyed. Certain cationic dyes have been specially developed since 1953 and are known loosely as [Pg.72]

Modified Basic Dyes. In comparison say with dyeings on cotton, the light fastness rises dramatically when these dyes are used on PAC fibres. [Pg.73]

4 Disperse. This class comprises dyes whose molecules are devoid of the common solubilizing groups but which have a minute solubility in water and when milled to extremely fine particle size will dye secondary acetate. Disperse dyes have been developed for polyester fibres the dyeing of which may require the presence of swelling agents and the use of pressure to achieve higher temperatures. [Pg.73]

I he practical dyer is primarily interested in classification according to application. The constitutional groups will therefore only be classified briefly (see Colour Index, Vol. 3). [Pg.329]

There is little correlation between classifications according to chemical type and application properties. Application classifications are of most practical usefulness to the dyer. [Pg.519]

Due to the variety in porous structure, particle size and surface area, pure silica gels and powders find a very wide range of applications. Variation in preparation methods and parameters allows the tailoring of the substrate properties for specific application needs. The main features in the silica applications are its porosity, active surface, hardness, particle size and the viscous and thixotropic properties. Although most applications are based on a combination of those, a classification according to the main properties of interest may be set up. For references, the reader is referred to the works of Iler6 and Unger7 and to the references cited in chapter 8. [Pg.27]

Dyes may be classified according to their chemical structure or the method by which they are applied to the substrate. The dye manufacturers and dye chemists prefer the former approach of classifying dyes according to the chemical type. The dye users, however, prefer the latter approach of classification according to the application method. [Pg.261]

All of these documents stress a requirement for room classifications according to the concentration of non-viable airborne particles at 0.5 pm and larger. The EU GMPs subordinate classification of the various areas applicable to sterile manufacture according a broader based grading system. Grades A to D are defined in terms of a range of independent characteristics such as the concentration of non-viable airborne particles at two sizes in operational and non-operational conditions, the concentration of airborne... [Pg.2290]

There are different classifications for enamel, according to application or chemical composition. These are partly overlapping. In this section an introduction is given based on two classifications ... [Pg.433]

An essential element of the CVD process is the chemical reaction that occurs to produce the coating/film. The precursors that constitute the chemical reactants must, of course, contain the chemical elements that will ultimately constitute the coating. In addition, these precursors must be stable at room temperature, react cleanly in the reactor without side reactions, not condense in the transfer lines, and be easily produced. The number of CVD reactions that are currently used is quite extensive and a complete listing of every reaction is beyond the scope of this review. However, a classification according to the method to activate the reactions for generic reaction type with specific examples is given in what follows. This will provide the reader with an overview of the diversity of applications of CVD. [Pg.441]

There are several different directions in LM separation classifications according to module design configurations, according to transport mechanisms, according to applications, according to carrier type, and according to membrane support type. Below, these types of classifications are described and discussed briefly. [Pg.4]

The use of the international classification according to lubricant material application allows us to group lubricant materials that are made in different countries in the classes of the application area. This considerably facilitates the task of selecting the lubricant materials for the specific equipment. [Pg.66]

The scientific classification of materials according to their flow behavior corresponds, in a limited sense, to the classification according to their commercial application. A distinction is made here between thermo-plasts, fibers, elastomers, and thermosets. This classification naturally only applies at the application or processing temperature under consideration. [Pg.423]

The contemporary author on the periodic system, W.B. Jensen, uses the terms primary and secondary kinship, which should not be confused with the terms primary and secondary classification as used by the present author. A primary kinship as termed by Jensen results from secondary classification according to the terminology used in this book. W.B. Jensen, Computation and Mathematics with Applications, 12B, 487-509,1986. [Pg.293]
