Dyeing Process - an overview | ScienceDirect …

Dyeing and printing processes are value-added treatments for most textile materials. A dyeing process is the interaction between a dye and a fibre, as well as the movement of dye into the internal part of the fibre. Generally, a dyeing process involves adsorption (transfer of dyes from the aqueous solution onto the fibre surface) and diffusion (dyes diffused into the fibre).

Firing Clay: The Lowdown on the Ceramic Firing …

Drying can be speeded up by pre-heating the ware in the kiln to 176°F (80°C) for a few hours. This part of the firing, up to 212°F (100°C) is called water smoking, which causes the water in the pores between the clay crystals to evaporate. The next stage is to drive off the water which is chemically combined with the clay (remember the formula for clay is Al2O3•2SiO2•2H2O). This is ...

In this paper we describe the development of a chrome dry etch process on a new type of mask etch tool. One crucial goal was to minimize the CD etch bias. To meet this goal, a procedure for the direct characterization of CD etch bias was developed. The common methods for measuring the CD etch bias as resist-to-chrome CD difference, such as confocal optical microscope or SEM measurement, only ...
