The students were directly involved in their project activities and the report became essential to generate a lot of valuable information for the readers. It will therefore be highly appreciated if you kindly accept this report and consider it for final evaluation. We hereby declare that the work presented in this report entitled “Comparative study on sewing errors of different buyers in a knitwear industry” is our original work, not offered for a degree from any other university and all the resource of material uses for thesis have been duly acknowledged.

I hereby confirm that the above statement by the candidate is correct to the best of my knowledge. Mominur Rahman Assistant Professor and Head (in-charge) of the Department of Textile Engineering, Daffodil International University, whose valuable guidance helped us in this project. Finally, we will express my gratitude to all the management and non-management staff who helped us during the internship period and to all the individuals who had an impact in one way or another in completing our entire project.

This paper points out Different types of Defects which are the normal term in the article of garment industry. In this research, we discovered that it is exceptionally basic to think about various types of garment defects.

INTRODUCTION

  • Limitations of the study

Sewing is the way of joining two textured pieces together by using lines made with a needle and string. Various types of defects or deformities emerge in the field of sewing, which need to be reduced to maintain the necessary nature of clothing. Currently, the instant clothing is one of the packages in the clothing area.

The central motivation behind the use of quality standards is to provide consistency between products and product lines. Imperfection in the clothing industry is a typical wonder that inhibits the smooth rate of creation and spotlights low-quality goods that affect the general economy of the manufacturing facility. Sewing strategy is possibly the main stages in work-concentrated pieces of clothing adventure.

Quality defects that occur under this system ominously affect the quality of the thing and the profitability of the thing, and also increase the cost of production. The purpose of this assessment is to investigate whether the knitting age's method is leveled in a knitting creation adventure and to perceive the methodology with the most important rates of sewing shortage in sewing office finally to make suggestions for improving quality control.

Since its inception, it has greatly improved the effectiveness and profitability of the texture, apparel and needle companies. The different parts of a sewing machine and their capabilities help the operator to understand the working of a sewing machine. There are different types of sewing machines used in assembling garments.

The sewing machine controls the texture by taking care of the accessories and structures that are ideal for pinning to join the textures. That honor goes to a development that becomes so universal or far-reaching that it becomes mediocre. There were a few such creations, but few were as large as a sewing machine.

The sewing machine has its underlying foundation back in Europe's first industrial revolution, which started in the late eighteenth century. Mid-nineteenth-century American innovators created machines that could sew a pair of joins, albeit with a limited capacity to focus. None of these machines were efficient, but the possibility of a workable sewing machine was there, and individuals were determined to fix it. The first major breakthrough came around 1830.

Thimmonier was almost executed by the Parisian tailors, but persevered and made a surprisingly better sewing machine. These machines run on essentially more modest motors, unlike those of the mechanical sewing machines. It is largely the development that deals with the string on the needle and fixing the hover formed by the canister.

Presser foot: attached to the presser bar to hold the material firmly when cutting. Front panel: The cover, which provides lubrication access when empty, focuses on the needle bar, press bar and pickup switch. Significant defects: Defects that reduce the functionality, usability, marketability of the garment are called major defects.

This occurs when the yarns in the texture are pulled out of the fold and is more common in textures produced with consistent fiber yarns. Broken openings in the texture where you can see through the texture to the opposite side.

MATERIALS & METHODS

  • Sewing defects reports for LERROS, BESTSELLER & IOC buyer
  • Sewing defects reports for LERROS, BESTSELLER & IOC buyer
  • Sewing defects reports for LERROS, BESTSELLER & IOC buyer
  • Sewing defects reports for LERROS, BESTSELLER & IOC buyer
  • Sewing defects reports for LERROS, BESTSELLER & IOC buyer
  • Sewing defects reports for LERROS, BESTSELLER & IOC buyer
  • Sewing defects reports for LERROS, BESTSELLER & IOC buyer
  • Total faults inspected for different buyer
  • Weekly faults for LERROS buyer
  • Weekly faults for BESTSELLER buyer
  • Weekly faults for IOC buyer

In line 1 examined for LERROS buyer, line 2-8 was examined for BESTSELLER buyer and line 9 was reviewed for IOC buyer. That figure has top 5 flaws and they are open fold, opening, part up-down, hit stitch and finally fold. In line 1 examined for LERROS buyer, line 2-8 reviewed for BESTSELLER buyer and line 9 assessed for IOC buyer.

That figure has the top 5 flaws, namely skip, part up, open fold, gap and finally rough edge. Line 1 inspected for LERROS buyer, lines 2-8 inspected for BESTSELLER buyer and line 9 inspected for IOC buyer. That figure highlights the top 5 faults and these are open seam, dirty spots, rough edge, part up and fold.

In this picture, the 5 most common defects are highlighted, which are part up-down, dirty spot, fold, open seam. This issue highlights the 5 most common mistakes and they are folds, part up and down, open seam, skip seam and dirty spot. Line 1 checked for buyer LERROS, lines 2-8 checked for buyer BESTSELLER and line 9 checked for.

That figure highlights top 5 mistakes and they are pleat, part up-down, skip stitch, open seam and broken stitch. Where BESTSELLER buyer errors are 917 pcs & LERRPS buyer errors are 289 & IOC buyer errors are 296 items of garments.

DISCUSSION OF RESULTS

  • Total work sheet for different buyer
  • Faults percentage for different buyer
  • Total Faults Percentage for Different buyer
  • D.H.U Percentage for different buyer
  • Inspection & Pass Goods Percentage
  • Overall Results
  • Discussion

In Chart 1 we see that weekly column worksheet with different categories such as inspection, defects and pass for three different buyers such as LERROS, BESTSELLER and IOC. In table 4 we see the error rate for different buyers, with higher errors being BESTSELLER (917) buyer and lower errors being LERROS (289) buyer. Where the blue color indicates that the buyer error percentage of LERROS is 289 (19%), the red color indicates that the buyer error percentage of BESTSELLER is 917 (61%) and the yellow color shows that the buyer error percentage of IOC is 296 ( 20%).

From chart 4 we see the weekly columns that different buyers weekly D.H.U (defects per hundred units) percentage. In chart 5, the blue color shows the total percentage of goods inspected and the red color shows the total percentage of goods allowed.
