wool easier dye compaire to nylon made made
Nylon, a synthetic fiber also sometimes labeled as polyamide, can be dyed with either of two completely different dye classes, acid dyes and disperse dyes. Both of these types of dye require the application of heat to fix the dye to the nylon, so be sure the item you are dyeing can withstand the heat called for in the recipe you choose. (This is a problem for nylon/Lycra blends, as the spandex fiber is heat-sensitive, made from polyurethane fiber. Use acid dyes on these blends, and carefully avoid stressing the fabric while it is hot, such as by twisting or stretching; temperatures above that indicated on the garment's care label (usually 105°F) may deform the shape of the garment.)
acid dyes
Nylon is a synthetic fiber, but its unique chemistry means that it can be dyed, easily and well, using the same acid dyes that are commonly used on wool and other animal fibers. A typical recipe calls for dissolving dye and salt in enough water to cover the material and allow it to move freely in the pot, adding the material, heat it to a simmer for ten minutes, add vinegar and simmer another ten minutes, then allow to cool gradually and rinse out. Microwaving or steaming might be used as an alternative form of heat application, if the dye is painted onto vinegar-water-soaked material, as in the case of tie-dyeing nylon.
