Basic dyes are usually applied in a batch process with skein, stock, and package dyeing more prevalent than piece dyeing on becks or jet machines. The fundamental steps in the acrylic dying mechanism are: absorption of the basic dyestuff at the fiber surface, which occurs only when the glass transition point of the fiber is exceeded; diffusion.
The process of attachment of the dye molecule to the fiber is one of absorption: that is the dye molecules concentrate on the fiber surface.

There are several different categories of hair dye each with overlapping, but distinct, ingredients. There are permanent, semi-permanent, demi-permanent, and temporary ones; as you add permanency, you also add harsher chemicals and thus the less permanent the dye, the safer it is for your hair.
Basically, the dyeing process is all about absorption and diffusion. Absorption is transferring of dyes from the aqueous solution onto the fabric surface and diffusion.

This chapter discusses the fundamentals and chemistry and efficiencies of the fenton process, ozonation, electrochemical oxidation, and photocatalysis processes.
Staining is a technique used to enhance contrast in samples, generally at the microscopic level. Stains and dyes are frequently used in histology (the study of tissue under the microscope) and in the medical fields of histopathology, hematology, and cytopathology that focus on the study and diagnoses of disease at a microscopic level.

The chapter is divided into three broad sections, namely, classification of dyes, environmental issues associated with different dye classes and the environmental-friendly dyeing processes. Among the different dye classes, dyes based on azo structure are found to be associated with human toxicity; as a result there is a ban on several azo dyes.
