Printing of Cotton Fabric With Pigment

Pigment Printing

Pigment printing has gained much importance today and is the most commonly used technique for most fibers. Pigments can be used on almost all types of textile substrates. There are two types of screen printing.
  1. Rotary Screen Printing
  2. Flat Screen Printing

Objectives of Pigment Printing

  • To print the fabric with print
  • To know the function of used chemicals in printing
  • To get the desired design of goods
  • To get knowledge about pigment printing
  • To get the desired shade
  • To print cotton fabric

Sample Nature

100 % Cotton Knitted Fabric

Apparatus Required for Printing

  • Beaker 
  • Glass Rod
  • Pipette
  • \Electric Balance
  • Measuring Cylinder
  • Screen
  • Squeezer
  • Curing Machine

Recipe Used for Pigment Printing

Sequestering Agent - 10cc/L
Pigment - 20 gm/Kg
Urea - 100 gm/Kg
Binder - 200 gm/Kg
Fixer - 10 gm/kg
Thickener - 30 gm/kg
Acetic Acid - 10cc/L

Function of Used Chemicals

  • Sequestering Agent: Remove the hardness of water
  • Pigment: Impart color to the printing paste
  • Binder: Give stickiness and plasticity to the printing paste
  • Fixer: It helps the binder to fixation
  • Thickener: Increase the viscosity of the print paste
  • Urea; Helps to fix the color of the fabric

Preparation of Printing Paste:

  • At first, we take the required amount of pigment in a bath
  • Then, a little amount of water is added to the pigment to mix the pigment
  • Then required amount of thickener and glycerine is added
  • The pigment mixer is stirred for a few minutes

Screen Printing Method:

  • The fabric is placed on the printing table of the flat-screen printing machine
  • Then the screen is placed on the sample fabric
  • The printing paste is taken on the screen perforation
  • Thus we can find the printed fabric with a smooth modern strike the paste is spread over the screen with slight pressure
  • So that, the pigment particles can penetrate through the screen perforation
  • Thus, we get the printed fabric

After-treatment of Pigment Printing

The printed fabric is steamed for (5-10) minutes in a cottage steamer and washed with cold water to remove unfixed pigment

 Desizing Process in the Textile Industry Desizing Desizing is the process of removing sizing material from the warp yarns of woven fabric. Sizing chemical consists of soluble starch material, a coupling agent, a lubricant,  and, a range of additives Types of Desizig Method: 1. Hydrolytic Method Rot steep Acid steep Enzymatic steep 2. Oxidative Method Chlorine Chloride Bromide Objectives of Desizing To remove the sizing material from the fabric To increase the absorbency power of the fabric To increase the affinity of the fabric to the dyeing chemical To make the fabric suitable for the next process Steeping It is the process where soaking in the liquid (water) of a solid to extract flavors or to soften it. Rot Steeping In rot steeping, the steeping cloth is passed through warm water of 40-degredegreeserature. For this clot, it is squeezed up to 100% expression by a squeezed roller and kept in washing for 24 hours. Advantages Desizing agent warm water, no special chemical is u...

Dyes Used in Textile Industry Textile Dyes Dyes are colored organic compounds that impart color to various substrates including paper, leather, fur, hair, drugs, cosmetics and waxes, and textile materials. Dyes are normally used in solution, which is capable of being fixed to a fabric. According to the Application Form Classification of Dyes: 1. Ready-made Dyes A.Water Soluble Dyes Direct (Cotton) Acid (Wool, Silk) Basic (Jute, Acrylic) Reactive  B. Water Insoluble Dyes Vat (Denim) Sulphur (Umbrella Cloth) Disperse (Polyester) 2. Ingrain Dyes Azoic  Oxidation Color Mineral Color Suitability of Various Dye-Classes for Textile Fibers: Cellulosic (Cotton/viscose) - Direct, reactive, vat, sulfur, oxidative, azoic, etc.   Cellulosic (Jute) - Basic dyes are widely used. Protein (Wool, Silk, Nylon) - Acid dyes are mainly used Polyester, cellulose, acetate - disperse dyes are mainly used Ways of Coloration: Direct dyeing, in which the dye from the solution in contact with the tex...

  Dyeing Process of Cotton Fabric With Sulphur Dyes Sulphur Dyes Sulphur dyes are highly colored, water-insoluble compounds and have to be converted into Water Soluble substantive forms before application to the textile materials. This conversion is carried out by a treatment with a reducing agent like dilute aqueous Na2S. Apparatus Required for Dyeing Beaker Glass Rod Cylinder Electric Balance  Thermometer Dryer Nature of the Sample: 100 % cotton knitted fabric Objectives of Sulphur Dyeing: To learn about how to cotton fabric dyeing with sulphur dyes To know about sulphur dyes To get an idea about the function of used dyeing chemicals To know how to improve the dyeing process Function of Used Dyeing Chemicals Sequestering Agent- To remove the hardness from water Alkali - It converts oil into water-soluble fatty acid and soap Salt - It acts as a catalyst that accelerates absorption rate and reduces surface tension.  Hydrose - It acts as a reducing agent H2O2 - It help...
