Direct Dyes

Direct Dyes are commonly used on cotton fibers. These Dyes are mixed in all purpose dyes along with the Acid Dyes. The color of Direct dyes on cotton fibers is not bright in respect to other dyes. The wash fastness of these dyes is not very good. The only advantage of these dyes is that the light fastness is little more better. Lightfastness means the resistant capacity against fading in light. But, this is also in few cases only. One more benefit of using Direct Dyes is that these can be used in the same dye bath with the Acid Dyes.

If anyone wants to get desired result by mixing Direct Dyes with unmixed cellulose then he/she will have to take these direct dyes in their pure form unless the use of these dyes become worthless. It is preferable to use direct dyes on the cellulose fibers. But if these dyes are accompanied with 'reserving agents' then these can be also used on stain silk and wool. But, unfortunately the 'reserving agent' is not available to home dyers.
