solution dyed carpet. Solution dyeing is a yarn coloration process in which pigment is added to the polymer melt before the fiber is extruded into yarn. The color, therefore, is an inherent part of the yarn itself. Although solution dyeing does not offer as wide a color selection as other dye methods, its colors are the most permanent.
Acid dyes are water-soluble anionic dyes that are applied to fibers such as silk, wool, nylon and modified acrylic fibers using neutral to acid dye baths. Attachment to the fiber is attributed, at least partly, to salt formation between anionic groups in the dyes and cationic groups in the fiber.irect or substantive dyeing is normally carried out in a neutral or slightly alkaline dyebath, 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, silk and nylon.
