Measuring DHU in Garments Sewing Line, Cutting, and Finishing

Measuring DHU in Garments Sewing Line, Cutting, and Finishing Section

DHU is “Defects per Hundred Units”, which means the total number of defects found per 100 units of garments. DHU is a quality performance measuring tool used for garment sewing lines and finishing sections. DHU results show the percentage of effects of the Garment industry. We can get defects in the real scenario by DHU, every Garments industry checks their DHU report and works to improve. To improve the quality garment industry needs to reduce DHU. In this article, we are discussing Measuring DHU in the Garments Sewing Line, Cutting, and Finishing Section.

For DHU, Record all the defects found during the inspection. It is crucial to document the type and frequency of defects. By tracking DHU, manufacturers can implement process improvements to reduce defects and improve overall product quality.

How to Measure DHU?

DHU calculation is very simple but it’s important to factor for quality control. To measure DHU, we need to know two things: –

1. Total quality inspection/ check quantity
2. Total number of defects (Not defective) 

Defects per hundred units (DHU) = (Total Number of Defects Found × 100)/Total Pieces Checked

We need the total Quality inspection quantity and total defects quantity to find out DHU.

For Example, A Sewing section produced 2000 pieces in a day, 93 were total Sewing defects found in quality inspection.

So the DHU of that is = (93 X 100)/2000

= 4.65%

Measuring Finishing section DHU

Here is the example of finishing; –

Suppose, Total inspection quantity- 355 | Total defects quantity- 27

So finishing DHU is = (27 X 100) / 355

= 7.60 %

Measuring Cutting section DHU

Here is the example of the Cutting section; –

Suppose the total inspection quantity- 1950 | Total defects quantity- 23

So finishing DHU is = (23 X 100) / 1950

= 1.18 %We can measure the DHU of any section in the same way.

Measuring Finishing section DHU

Here is the example of finishing; –

Suppose, Total inspection quantity- 355 | Total defects quantity- 27

So finishing DHU is = (27 X 100) / 355

= 7.60 %

Measuring Cutting section DHU

Here is the example of the Cutting section; –

Suppose the total inspection quantity- 1950 | Total defects quantity- 23

So finishing DHU is = (23 X 100) / 1950

= 1.18 % So, We can measure the DHU of any section in the same way.

By monitoring and measuring DHU throughout the production process of the Garments industry, you can ensure that each section—sewing, cutting, and finishing—is optimized for quality.
