Organ Gram Of Dyeing And Finishing Textile Industry

Dyeing and finishing are the combined section of textile industry. This dyeing and finishing industry could be based on Yarn, Knitted or Woven fabrics. Generally, finishing is done after dyeing process. After finishing, materials are sending to garments or printing section for further operation. In every organization there have a managerial system which control the whole process. There have various sections in an industry. Every section is related to the production and its assistance.

Organ gram Of Dyeing and Finishing Textile Industry: The dyeing and finishing textile industry is run by the following managerial system.

Chairman

Managing Director (MD)

Executive Director (ED)

Director (Production/ Finance)

General Manager (GM)

Deputy General Manager (DGM)

Assistant General Manager (AGM)

Manager (Dyeing/Finishing)

Assistant Manager (Dyeing/Finishing)

Senior Production Officer (SPO)

Production Officer (PO)

Assistant Production Officer (APO)

Dyeing Master

Shift In – Charge

Floor In – Charge

Supervisor

Operator

Helper

Above managerial system is must for better management. But it is very rear because all of the industries are not same in volume and not interested to main all of the class of the managerial system. For this reason, some part of the managerial system could be absent.

So, if anyone wants to get better production he or she should have to maintain the above managerial system.

Finished Fabric Inspection In Finishing Section | Types of Test In Finishing Section

Fabric Inspection is done in grey form or finished form. The inspection of fabric is a procedure by which the defects of fabric are identified and fabric is classified according to degree or intensity of defects. The fabric inspection is done for both grey and finished fabric.

Grey Fabric Inspection: After producing grey knit or woven fabric it requires to check out any types of fabric faults before sending in dyeing section. Most of the fabric manufacturing companies inspect grey fabric according to 4 point system.

Finished Fabric Inspection: The final product should pass against the norms given by the buyer. The following tests are done-

  1. Shade check
  2. GSM test
  3. Width or diameter test
  4. Shrinkage test
  5. Crocking test
  6. Pilling resistance test
  7. Color fastness to wash
  8. Color fastness to water
  9. Color fastness to perspiration
  10. Dimensional stability
  11. WPI & PPI

Different types of fabric faults can be found in a dyed finished fabric. The following defects are found in the final inspection.

  1. Uneven shade
  2. Oil spot
  3. Neps
  4. Crease mark
  5. Machine Stoppage mark
  6. Listing
  7. Line mark
  8. Pick missing
  9. Double yarn
  10. Dead cotton
  11. Bowing
  12. Fly yarn contamination

So, find out the defects of the finished goods and try to reduce the faults of the fabric.

Process Flow Chart of Dyeing Textile Materials | Basic Structure of Wet Processing Technology

Wet processing technology and its uses are huge in textile sector. Dyeing process for different textile materials could be different but its basic idea is same for all. For all types of dyeing pre-treatment is must for removing unwanted materials from textile materials. Pre-treatment style differs for the shade of dyed materials. Shade may be light or deep. Also these pre-treatment depends on buyer’s requirement. After pre-treatment textile materials are ready for dyeing. After dyeing after-treatment is necessary for get the final finished products. At last, that’s product becomes ready to use. This sequence can be expressed by a flow chart.

Basic Flow chart of dyeing textile materials is like the followings:

Grey Textile Materials (Fiber, Yarn or fabric)

Singeing

Desizing

Scouring

Bleaching

Mercerizing

DYEING/PRINTING

Finishing

Marketing

Now I like to discuss shortly about the different terms of the flow chat. Here, grey textile materials are fiber, yarn or fabric which is also consider as the raw materials for dyeing.

Singeing is the first steps of pre-treatment. The process by which loose, hairy and projecting fibers are removed is called Singeing.

Desizing is the second steps of pre-treatment. By this process gummy materials are removed. Also size materials removed by this process.

Scouring is the third steps of pre-treatment. This process is performed for removing impurities of the textile materials.

Bleaching is another important step which is used to reduce natural color of the raw materials. Dyeing performance depends on it much more.

Mercerizing is the special types of treatment. It performs if buyer wants. It is an additional treatment. It increases the strength and luster of the materials.

Dyeing is the main process where a white material becomes decorated by different colors. We have to know about the depth of shade of the materials.

Printing is called as localized dyeing. Different types of printing are done for giving special appearance on colored or white fabric.

Finishing is the last treatment of wet processing. Different types of properties can be added to the materials by different finishing effects.

Marketing is our main goal. Say, if we done everything but there have no buyer then everything is waste. So we should have a strong marketing department.

So, all of this is about flow chart of Dyeing.
