Pigments
Pigments are a special type of dyeing or printing material for wet processing technology. It is not so easy task to print or dye material with pigments, because the pigment is 100% water-insoluble. So it needs to take special techniques for pigment dyeing or printing. Generally, pigment is used for printing.
Pigments can be defined as a water-insoluble coloring material mostly of mineral origin that has been used for the coloration of metal, wood, stone, and textile materials. Pigments have different types of chemical characteristics. Some examples of pigments are as follow:
- Dioxazine
- Fluorubine
- Isoindoline
- Perylene perinone
- Pyrocoline
- Quinacridone
- ETC
Difference Between Dyes and Pigments
Dyes and pigments are the main coloring materials. So we have to know about the differences between dyes and pigments, which will give us a clear idea about these two. The following are the difference between dyes and pigments. They are-
| Dyes | Pigments |
|---|---|
| Generally, organic materials are dyed or print | Organic and inorganic both types are dyed or print |
| It is water-soluble | It is completely water insoluble |
| It contains auxochrome in their chemical structure | No auxo chrome contains in pigments |
| Colorfastness is generally average to excellent | Colorfastness is average to good |
| Its application method is very easy | Need binder for application |
| It is generally used for dyeing | Generally used for printing |
| Dyes are more expensive than pigments | Pigments are generally inexpensive than dyes |
| Dyes have an attraction to fibers | They have no attraction to fibers |
| It applies selectively to textile materials | All fibers can be color |
In sum, pigment is used to dye cotton fabric besides printing in modern times. Different types of pigment are supplied by different well-known dyes and pigment manufacturing companies.

Is Perspiration & Saliva fastness is builtin properties of pigments?
The topic was adequately addressed but not thoroughly. This article is in desperate need of editing. Several sentences make no sense. All-in-all I was not very impressed.
I like it what you have written, But I think you can write some more information on it. Because there are lots of information around pigments are available.
