Report on Industrial Training


By means of the practical knowledge it’s possible to apply the theoretical knowledge in the practical field. For any technical education practical experience is almost equally important in association with the theoretical knowledge. The training minimizes the gap between theoretical and practical knowledge and makes us familiar with the industrial environment, we got an opportunity to complete 6 weeks (42 days) long industrial training and I did it in Asian specialized textile mills limited which is consists of Fabric manufacturing  (yarn twisting, warping, sizing  and weaving) units. It has well planned & equipped. It also has a sister spinning factory.

The industrial attachment is the process which builds understanding skill & attitude of the performer, which improves his knowledge in boosting productivity & services. College education provides us vast theoretical knowledge as well as more practical attachment, despite all these industrial attachment help us to be familiar with the technical support of modern machinery, Knowledge about various operation stages.

It also provides us sufficient practical knowledge about production management, Productivity evaluation, work study, efficiency, industrial management, production planning & control, production cost analysis, inventory management, purchasing, utility & maintenance of machinery and their operation techniques etc. the above mentioned cannot be achieved successfully by means of theoretical knowledge only. This is why it should be accomplished with practical knowledge in which it is based on industrial attachment makes us reliable to be accustomed with the industrial atmosphere & improve courage & inspiration to take self responsibility.

Machine and equipment:


The parallel winding of a set of warp yarns from many yarn packages (cone/cheese) on a flanged bobbin (warping beam) at uniform specific tension and length is called Warping.


  • Wind the warp yarns on the warping beam to make it suitable for sizing.
  • In case of designable fabric wind the yarns section wise by sectional warping.

Requirement of Warping:

  • The yarns in the sheet should be in uniform spacing.
  • The yarns in the sheet should be in uniform tension.
  • The yarns in the sheet should be of a predetermined length.
  • The sheet should be containing a predetermined number of ends.
  • There should be no broken ends in the beam.

Types of Warping:


Direct warping is used for single color warping. Yarns are directly wound on the wrapers beam so it’s called direct warping.


Sectional warping is used for complex color patterns. Sections are made sequentially according to warp pattern.

Raw Material:

  • Cone (different count yarn) from Hard Winding Section.

weaving machine


Sizing is the process of giving a protective coating on the warp yarn to minimize yarn breakage during weaving.

Sizing is the most important operation in preparing warp yarn for weaving especially with cotton yarn. The smallest error in sizing process may be very harmful. This may increase warp breakage rate on the looms and consequently reduce weaving production and quality. Therefore sizing is termed as the “mother of Weaving”.


  • To increase the smoothness of the warp yarn.
  • To reduce hairiness of warp yarn.
  • To increase the strength of warp yarn.
  • In some cases sizing is now done to modify the character of the warp yarn. i.e. to have an effect on fabric weight on fabric weight, stiffness, handle properties etc.

Requirement of sizing:

  • Sized warp must be strong and elastic.
  • Yarn strength and loss in elongation should be within admitted limits.
  • The process must ensure the applications of required amount of size on the yarn.
  • The tension of warp yarn must be constant all the time.
  • The weavers beam must have a cylindrical shape, necessary winding density and the yarn length.
  • The sizing process must be efficient, economical and must ensure the production of high quality size warps.

Operation Procedure:

  • As a new beam is set to a loom either by drawing cam getting or tying, it is the task of loom technician to check & set all necessary setting, gauging & operating values through loom function panel & mechanical means. After all setting has been done, the loom function is checked by slow running or inching. The first meter of fabric is made normal running & cut off from the loom & checked over an inspection box against light.

The fabric is checked visually for-

        Any wrong pattern setting.

        Any wrong drawing & denting.

        Fabric width, warp & weft density.

        Any other cloth defect.

Any fault found in the fabric is corrected over the loom & it is handed over to the operator for normal running.

Production department:

 Description of production process:

In every mill, there maintains a sequences in production processing. It is also followed in this mill where we were in industrial attachment. The process sequences are in list below:

1) Firstly, weaving manager gets a production shit from the merchandiser as accordance as consumer requirements then he informs or orders production officer about it.

2) Production officer informs technical in charge and knows about machine in which the production will be running.

3) Technical in charge calls for leader of mechanical fitter troops, they two take decision about machine for production considering machine condition, production capacity, maintenance complexity, etc.

4) Production officer with experienced mechanical fitter adjusts required design and cam setting for required fabric.

5) Supervisor checks daily production regularity and make operator conscious about finishing tin due time.

6) Operators operate machine in high attention as if there were no faults in the fabrics. If he thinks or sure about any fabric fault, then he calls for the mechanical fitters in duty. Mechanical fitter then fixes it if he can or he informs technical in charge. Then he comes in spot.

7) After required production and final inspection in 4-point system, they sent in dyeing factory.

  • In our industrial attachment program contents some secret of factory is included. To collect this information like history of project development, costing of products, marketing strategy etc. every student face a great problem as it is a secret. So our proposal for our University authority to exclude these topics from the contents.
  • We had a very limited time. In spite of my willing to study more details it was not possible to do so.
  • This while process is not possible to bind such a small frame as this report, hence our effort spent on summarizing them.



Industrial attachment program send us to the expected destiny of practical life. The completion of tow month industrial attachment at Asian textile Ltd I have got the impression that the factory is one of the most modern woven project in Bangladesh. It has earned very good reputation for its best performance over any other woven project.

 During my industrial attachment program I had tried to my best to done my duty. My supervising officer also satisfied to me & offer co-operation in every steps. It is completely a new experience in my life, which will be very effective in my service life. During my training period I realized that practical experience is more valuable for service life.
