Process Flow Of Pigment Printing On Cotton fabric | Binding System

Pigments are mainly synthetic organic materials. It has no affinity to the fabric. For this reason, binder is used for making film on the pigment surface. A 3-dimensional cross linking is produced between fiber and pigment. After drying, curing is done at 150 – 180 degree Celsius for fixing the pigments on the fabric surface. Pigment printing is cheaper than other printing process.

Here, I have given a sequence of pigment printing on the cotton fabric.

Recipe: This is a sample printing recipe. It can be change depending on the color depth.

Thickener——2%

Binder——–8%

Fixer———-2%

Water———90%

Sequence of Pigment Printing: Pigment printing is carried out as the following way.

 

Fabric Pre-treatment

Table preparation

Fabric plaited on the table

Pigment printing paste apply with the help of screen

Curing at 160ºc (belt speed 6.50 m/min)

Delivery

 

Pigment printing process is interesting one. So, print your knit or woven fabrics with pigments and enjoy wearing a pigment printed T-Shirt or Polo-Shirt.

What Is Pigment Printing | Advantages And Disadvantages of Pigment Printing

Pigments are mainly synthetic organic materials. Pigment printing is done to produce attractive design by applying pigment paste on the fabric surface. Pigments are found in particle state and the particle size range should be in the region of 0.1 – 3 microns.

Pigment printing is done with binder system. We know that pigment has no affinity to cotton fabric for this reason binder is required during printing. The binder is a film forming substance made up of long macromolecules which when applied to the textile materials together with the pigment, produce a 3-dimensional networked. The 3-dimensional links are formed during some suitable fixing process, which usually consist of dry heat and change in pH value (<5), bringing about self-cross linking or reaction with suitable cross-linking agent. This cross-linking improves the elasticity and adhesion of the film to the substrate.

Pigment printing has lots of advantages and disadvantages. Following is the advantages and disadvantages of pigment printing.

Advantages of Pigment Printing

  1. Pigment can be applied for natural as well as synthetic fibers.
  2. Pigment print is an easy task for the printer.
  3. Pigment printing is most economical printing process.
  4. Pigment printing allows maximum output of goods.
  5. Fastness properties are good to average.
  6. Well defined design can be produced by pigment printing.

Disadvantages of Pigment Printing

  1. Pigment printed textile wears are not comfortable to wear.
  2. Pigments are sensitible to crushing during roller printing.
  3. Rubbing fastness is medium.
  4. Pigments are completely fast to dry cleaning.

So, print your T-Shirt, Polo-shirt or other textile materials with pigment and get various attractive designs.

What is Pigments || Comparison between Dyes and Pigments

Pigments are the special type of dyeing or printing materials for wet processing technology. It is not so easy task to print or dye a material by pigments, because pigment is 100% water insoluble. So it needs to take special technique for pigment dyeing or printing. Generally pigment is use for printing.

Pigments can be define as a water insoluble coloring material mostly mineral origin have been used for coloration of metal, wood, stone and textile materials. Pigments have different types of chemical characteristics. Some examples of pigments are given bellow:

  1. Dioxazine
  2. Fluorubine
  3. Isoindoline
  4. Perylene perinone
  5. Pyrocoline
  6. Quinacridone
  7. ETC

Dyes and pigments are the main coloring materials. So we have to know about the comparison between dyes and pigments, which will give us a clear idea about this two.

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 auxo chrome in their chemical structure No auxo chrome contains in pigments
Color fastness generally average to excellent Color factness 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 expensive than pigments Pigments are generally inexpensive than dyes
Dyes have attraction for fibers They have no attraction for fibers
It applies selectively on textile materials All fibers can be color

In modern times pigment use to dyeing cotton fabric besides printing. Different types of pigment are supplied by different well known dye and pigment manufacturing companies.
