  1. Pigments are not soluble in water
  2. Pigments are also not soluble in acid and
  3. Pigments don’t have addiction with fiber so these pigments are attached with fiber or cloth by binder.
  4. Wet fastness and light fastness are good but rubbing fastness is not good for heavy shade.
  5. Pigments can gives us the bright and ideal shade from any color.
  6. Pigment can reduce the toxicity problem.
  7. Frequent Laundry can reduce light and rubbing fastness.
  8. The application of pigments is easy and this pigments price is less than others.
  9. Pigment doesn’t make a bond with fiber or fabric.
  10. Pigment is not able to gives is the exact color.
  11. Pigment doesn’t recommended expensive machine to do this process.

Classification & description with trade name of Mordant dyes and methods of mordant dyeing.

Mordant is a word which is related with hydrophobic fiber dyeing is come from a Latin word mrdaeo means some material which is Strongly cling with something’s. Mordant is essential equipments which are used to make mordant dying to attach with fiber so hardly. An organic compound named tannic acid can be listed with mordant. Now a day the material is used so much with mordant dyeing is called chromium. So that mordant dyes also called chrome dye. This type of dyes is specially good for synthetic fiber.

 

Mordant dyes react with metal oxide and make insoluble pigment. The ancient time so many dyes source are come from vegetable like madder, log wood, fustic etc. the other hand so many dyes come from some moth like cochineal, kerness, lakha etc.

 

Mordant Color
Aluminum Oxide Red
Tin Oxide Pink

Properties of disperse dye

  • Disperse dye are a little soluble in water and its makes fine dispersion in water. Disperse dyes are fully soluble in organic compound like tuluin and benign.
  • Light fastness of disperse dyes are from fair to good ratted. The ratting of disperse dyes are from 4 to five.
  • Because of hydrophobic character this dyes are not so good at washing fastness. The ratting of washing fastness is from medium to good.
  • This dye is good for hydrophobic fiber like polyester, nylon, acrylic Etc.
  • Disperse dye has not attraction to cellulose and regenerated fiber.
  • Disperse dye able to gives us the medium and bright shade.
  • Rubbing fastness is good for disperse dye
  • Disperse dye is used by neutral or a little aside solution.
