Salt helps by making the dye solution stick to the cloth fibers.
Generally, most synthetic fibers like polyester take up dye poorly, if at all. In contrast, natural fibers like cotton absorb dyes readily.
Wool dyes so well because it has fibers that absorb color. The filament is very fine in wool. It can be dyed almost any color.
Disperse Dye is an organic dye used to dye cellulose acetate and are water soluble. These dyes are mainly use in dying of polyester, nylon and acrylic fibers.
Fruit punch stains clothes because it contains a dye. The fibers of the clothes absorb the fruit punch. The liquid part of the drink evaporates, and the dye part remains set in the fibers of the clothes.
Cotton and wool do take dye really well where as linen and most other matrials do not hold it well, youll sort of get a faded version of what it should look like which will fade even further in the wash. Not sure if this was the answer you were looking for, but i do hope it was a bit helpful (:
Yes, wool fibers can be dyed, indeed this is how the colored natural wool that is used to knit warm garments are given their color.
You would have to be sure that the lampshade is made of natural fibers and does not have a coating that would prevent a dye from being absorbed. Wear gloves and use a sponge to apply the fabric dye. Make sure to let it dry completely.
Some wool is naturally colored. White wool can be dyed, if the dye is accompanied by an agent called a mordant, which prepares the fibers to accept the dye.
A fiber reactive dye react with the material, is chemically linked to these fibers.
No, you cant it will REALLY damage your hair =/
