Process of dyeing andfinishing


10/20

Process1. Storage:

The grey fabric is received from

suppliers, Nishat, Shafi & Eshaq textiles.

Placed in huge bulks.

2. Singeing:

Designed to burn off the rough surface to producesmoothness.

The fabric passes over brushes to raise the fibres, andthen passes over a plate heated by gas flames.

The cloth then also goes through the washers (heatedcylinders to dry the cloth).

3. Desizing:

Starch is removed through enzymes.

4. Bleaching:

Turns the grey fabric in to white.

It improves whiteness by removing natural coloration

and remaining trace impurities from the cotton; the

degree of bleaching necessary is determined by the

required whiteness and absorbency.

Cotton will be bleached using an oxidizing agent, suchas dilute sodium hypochlorite or dilute hydrogen

peroxide. If the fabric is to be dyed a deep shade, then

lower levels of bleaching are acceptable.


12/20

5. Mercerizing:

fabric is treated with caustic soda solution to causeswelling of the fibres.

This results in improved lustre, strength and dyeaffinity.

Cotton is mercerized under tension

All alkali must be washed out before the tension is

released or shrinkage will take place.


13/20

6. Colour matching:

Lab testing is done for shade checking, colorfastness and shrinkage of fabric to ensure that how

the color turns out on the cloth. First they do light shading to check whether the

color is right or not.

Physical testing

7. Shrinking: Mechanical shrinking (sometimes referred to as

sanforizing) is where the fabric is forced to shrinkwidth and/or lengthwise,


14/20

8. Dyeing:

Chemicals are imported from Switzerland andChina

There are five categories of dyes

imparting color on fabrics.

After color matching in the lab testing the fabric isrun through the dyeing machine called thermaland steamers for one particular color.

Reactive Disperse Pigment Inks Vat Dyes

9. Tentering:

Widths are set via dryingand heat treatment.

Aligns the fabric andgives stable widths anddimensional stability.

10. Colour Judging: Here the dyed fabric is

checked for its colour.


16/20

11. PrintingRotary screen printing cylindrical screens are made. Engraving screens are made according to different designs via rollers on cylinders

fed by the computer.

As the cloth moves between the rotating drum and rollers picks up colourfrom the engraved area of each roller in sequence.

Flat-bed screen printing fabric design is reproduced on fine mesh screens. On each screen, the areas in the design that are not to be penetrated by the

dye are covered with lacquer or some other dye-resistant coating. The screens are coated with dye on the back and mounted in the proper

sequence above a flat bed. As a belt carries the fabric along from screen toscreen, a roller presses the dye through the open area of the screen onto thefabric.

12. Digital Screening:

time saving simple process as it requires no engraving.

printing is done via ink printers (MSJP7). machine imprints the pattern of various colors at one time in a

repetitive manner.

13. Finishing: Thorough inspection is done. If defects, employees will inspect whether they are from grey

fabrics or from processes. fabric without defects will be rolled up into a bolt. Then folded rolls tagged as finished goods and is sent for

packaging for delivering it to the suppliers.

14. Folding and packaging: In this final stage the product is ready for supply.


18/20

RecommendationsHuman Resources Development The Textile Board should establish a separate training wing,

where training courses should be conducted for the capacitybuilding of labour.

There is also urgent need to increase the number of suchVocational Institutions where modern technical education isprovided.

Safety materials Provision of masks for prevention from toxic chemicals while

working in the chemical department.

Expansion of digital printing Expansion. Initial cost will be high but they will have long term benefits as

it is a simple and a time saving process.
