Basic dyes are also used in the coloration of paper. Direct or substantive dyeing is normally carried out in a neutral or slightly alkaline dye bath, at or near boiling point, with the addition of either sodium chloride (NaCl) or sodium sulfate (Na 2 SO 4) or sodium carbonate (Na 2 CO 3). Direct dyes are used on cotton, paper, leather, wool ...
Adjective dyes are those dyes that require use of a mordant to bind the color to the fiber. [2] alkanet Alkanet or dyer's bugloss (Alkanna tinctoria) is a traditional plant source of red dye. [3] alum Alum (aluminum sulfate) is a naturally occurring basic mordant widely used in the ancient world. [4] añil
Different classes of dyes are used for different types of fiber and at different stages of the textile production process, from loose fibers through yarn and cloth to complete garments. Acrylic fibers are dyed with basic dyes, while nylon and protein fibers such as wool and silk are dyed with acid dyes, and polyester yarn is dyed with dispersed ...
It describes the appearance of cells, tissues and cellular structures as seen through the microscope after a histological section has been stained with a basic dye. The most common such dye is haematoxylin. The name basophilic refers to the characteristic of these structures to be stained very well by basic dyes. This can be explained by their ...

An acid dye is a dye that is typically applied to a textile at low pH. They are mainly used to dye wool, not cotton fabrics. [1] Some acid dyes are used as food colorants, [2] [3] and some can also be used to stain organelles in the medical field. Acid dyes are anionic, soluble in water and are essentially applied from acidic bath.
Micromass cultures of C3H-10T1/2 cells at varied oxygen tensions stained with Alcian blue. Alcian blue (/ ˈ æ l ʃ ə n /) is any member of a family of polyvalent basic dyes, of which the Alcian blue 8G (also called Ingrain blue 1, and C.I. 74240, formerly called Alcian blue 8GX from the name of a batch of an ICI product) has been historically the most common and the most reliable member.

Natural dyes are dyes or colorants derived from plants, invertebrates, or minerals. The majority of natural dyes are vegetable dyes from plant sources—roots, berries, bark, leaves, and wood—and other biological sources such as fungi. [1] Archaeologists have found evidence of textile dyeing dating back to the Neolithic period.
