We declare that this internship report has been prepared by us under the supervision of Mme. We also declare that neither this report nor any part thereof has been submitted elsewhere for the award of any degree. First of all we express our sincere thanks and gratitude to Almighty Allah for His divine blessing which enables us to complete our industrial attachment.
Deep knowledge and great interest of our supervisor in the field of painting influenced us to carry out this industrial attachment. His endless patience, expert guidance, constant encouragement, constant and energetic supervision, constructive criticism, valuable advice, reading many inferior drafts and correcting them at all stages made it possible to complete this Industrial Appendix. Mahbub-Ul-Haque Majumder, Dean, Faculty of Natural Sciences and Information Technology, Daffodil International University for his continuous guidance in preparing this Industrial Annexure.
Mahbubul Haque, Head, Department of Textile Engineering, Faculty of Natural Sciences and Information Technology, Daffodil International University for his kind help in completing our Industrial Annexure. Finally, we must acknowledge with due respect the constant support and patients of our parents.

CHAPTER: 03 Dyeing Lab Department
Lab Dip Development means the sample which is dyed according to the buyer's requirement (similar shade and so on). Computer color matching system (CCMS) is the latest system to predict and analyze the color of the sample. In 1963 it was first introduced by ICI Company, but it was introduced International Color System in 1973.

Dyeing Procedure of polyester fabrics with Curve
Uneven dyeing in a rope occurs due to uneven pre-treatments and rapid addition of dyes and chemicals. Variation in rope-to-rope shades occurs due to incorrect rope length and fabric flow rate in different nozzles on dyeing machine. If a color parameter (time, temperature, liquid ratio, etc.) is changed, problems arise with the reproducibility of batch-to-batch shades.
This problem occurs when operators do not properly dissolve the dye in the right amount of water. This type of fault is found after dyeing due to yarn batch or count mix in fabric. This problem occurs due to the machine being overloaded with fabric and due to the absence of sufficient amount of liquid in the machine during the process.
Band marks are found in folded areas of wet dyed fabric due to dye migration. Shades change along the length of the dyed fabric due to changes in the concentration of the dye liquid. This problem occurs in the width of the dyed fabric due to the uneven pressure of the padded rollers.
During continuous dyeing, it occurs due to improper impregnation of the fabric in the pad trough and uneven heating in the machine. Occurs during continuous painting due to excessive foaming in the pad trough and insufficient pretreatment.

WTP (Water treatment plant)
A treatment plant is a facility where the textile industry collects groundwater and removes water impurities for the textile dyeing process. The cleaning device is very important, because without proper water treatment (that means removing all impurities from the water) textile dyeing will not proceed properly.
CHAPTER: 09
ETP (Effluent treatment plant)
ETP (Effluent Treatment Plant) is a process design for the treatment of industrial waste water with a view to reuse or safe disposal to the environment. Because without ETP, the polluted water is polluted to the environment, that is why the environment is polluted by this polluted water. 9.3- Biological ETP: Biological ETP is the process in which the wastewater is treated with the help of microorganisms (mostly use bacteria).
In the ETP biological plant, bacteria remove or reduce the concentration of the organic or inorganic compound.
CHAPTER: 10
Maintenance
In engineering, we use this terminology to maintain smooth and uninterrupted performance of machines, tools and metallurgical properties in practical use.

Impact of Internship
With the help of practical knowledge, it is possible to apply theoretical knowledge in the practical field. For any technical education, practical experience is almost as important as theoretical knowledge. Industrial attachment is a process that builds a contractor's understanding and attitude, which improves their skills in increasing productivity and service.
A university education gives us extensive theoretical knowledge and more practical attachment, and despite all these industrial attachments, it helps us to know the technical support of modern machines, skilled at different working levels. It also provides us with enough practical knowledge of production management, productivity evaluation, work study, efficiency, industrial management, production planning and control, production cost analysis, inventory management, procurement, utility and maintenance of machines and their operational techniques, etc. Therefore, it must be achieved through practical knowledge based on industrial attachment, which makes us reliable, accustomed to the industrial atmosphere and increases the courage and inspiration to assume our own responsibility.
CHAPTER: 15 Conclusion
We have got the impression that the factory is one of the most knitted dyeing projects in Bangladesh. Although it was established 15 years ago, it has gained a very good reputation for its best performance compared to any other knit dyeing project. During our industrial attachment program we had tried our best to do our duty.
It is a completely new experience in our life, which will be very effective in our life.
