Padding method

Pad Method 1% to 2% of CNC SOFT TD based on the total volume of finishing liquor is normally sufficient. 

Cationic softener/napping assistant, which imparts a soft, full, bulky hand to synthetic and natural fibers. HYDROSOFT CBA may be applied by either exhaust or pad methods. 

Cationic softener that imparts a full, soft hand without adverse effect on water absorbency of cotton. Designed for finishing toweling, hosiery, and other goods where absorbency is critical. Resists yellowing, scorching. Can be applied by exhaust or pad methods. 

The use of vat dyes in pigment form for cheeses and rayon cakes suggested improved techniques for various continuous and semi-continuous padding methods for the application of vat dyes to piece goods. Most vat dyes are now marketed in forms specially prepared to yield relatively stable dispersions of extremely finely-divided particles required for pigmentation. Fhe earliest and simplest procedure was the so-called pigment-pad process illustrated diagrammatically in Fig. 20.3 Ciba review. No. 120). In this case... 

The method of application is basically similar to the chlorotriazinyl dyes. The dyebath is made up with SO to 100 g per litre of common salt and fixation is brought about by the addition of 30 to 40 g per litre of soda ash, 20 to 30 g per litre of trisodium phosphate or 1-5 to 7 ml of sodium hydroxide (66°Tw 23 per cent). The temperature necessary for fixation varies from 80 C (176°F) to 90°C (198°F) according to the dye and the method of application. When these dyes are applied in a winch or a package machine the dye, salt, and alkali can all be added at the commencement because there is little danger of the reactive group becoming hydrolysed before it has reacted with the cellulose. The trichloropyrimidyl dyes do not exhaust easily and padding methods are therefore preferable. 

The double padding method makes it possible to work with a very stable stock solution of the dye containing no alkali whatsoever. The cloth is first padded with the dye solution and then dried, after which it is impregnated with alkali and salt. It then passes into a steaming chamber where the dyestuff is fixed, and finally washed off. The sequence of operations is illustrated diagrammatically in Fig. 22.7. There are other permutations of the sequence of events in continuous ranges but, with the exception...

The exposure pad method, combined with measurement of urinary metabolites, has been used to compare worker exposure for different pesticide application methods (33, 34) as well as to monitor formulating plant worker exposure (35) and homeowner exposure (36). 

The fact that a relationship similar to Eq. (8) was experimentally found for solid acid catalysts has both practical and theoretical significance. From a practical point of view, it demonstrates that at least one experimental method exists, namely the PAD method, that affords a direct and quantitative determination of both the number and strength of Bronsted acid sites on surfaces of porous oxide catalysts. 

The rubber pad method has one tool surface that provides a precise shape and a compliant rubber pad that deforms as an incompressible fluid to deliver pressure to the composite. 

The following example emphasizes the selectivity of the HPAE-PAD method in a different way. Figure 3.256 shows the separation of the oligosaccharides listed in Table 3.32 that can exist in glycoproteins. 

Although structures 3, 10, and 12 exhibit different compositions, their hydro-dynamic volumes are very similar. The hydrodynamic volume of an oligosaccharide can be determined via the determination of glucose equivalents by means of ion-exclusion chromatography. Structures 10 and 12, which differ by only 0.1 glucose equivalents, can easily be separated by the HPAE-PAD method, whereas the separation by ion-exclusion chromatography is extremely difficult. 

It can also be seen from Figure 3.256 that the HPAE-PAD method can be applied for the separation of linkage isomers of charged oligosaccharides. The...
