Acid Dyes

Written October 16, 2019

Acid dyes are best used to print on wool, angora, cashmere, silk and polyamides. Nylons are also printed using this type of dye. The fibers in these materials have positively charged ions that are naturally attracted to the negatively charged ions within the acid dyes. The acid-dye ink is printed directly to the textile, and then a steam setting process applies heat. The steaming enhances the attraction between the textile and ink molecules and forms a powerful union between the two. At the end of the steaming process, excess dyes are removed in a rinse or wash stage. Post processing: steaming, then rinse or wash to remove excess dye Markets: Fashion textiles, indoor soft signage
