If you want to ensure quality and continuous improvement then you have to avoid the following defects of the garments.

  1. Fabric defect
  2. Trims and accessories defect
  3. Cutting defect
  4. Construction and placement Defect
  5. Seam and Stitching Defect
  6. Finishing defect
  7. Packing defect

Let’s have a short discussion about these quality factors/matters

Fabric Defect

Fabric cost is at least 60% out of total garment Cost. Apparel Industry inspect fabric roll for quality matter. If your fabric roll fail in inspection you should return to fabric supplier and replace with the quality one. If your finished garment contains fabric defect, you are the one who will be responsible for that not fabric supplier.

Trims and Accessories Defect

Apparel industry should check all trims and accessories after in housed. If they found any problem, they should return to suppliers for replacement.

Cutting Defect

As per Running shade and Selvage report, marker will make for bulk cutting. Otherwise garments will contain part shading. All cut components should match with marker.

Construction and Placement Defect

You will sewing garments as per buyer’s approved sample for bulk production. All stitching of every process should same as sample. Different parts placement should accurate. Up-down is not acceptable.

Seam and Stitching Defect

All sewing machine should fit for sewing with accurate tension. Otherwise there are possibilities of skip stitches, puckering. Garments should be clear of some other stitching defects like: broken stitch, over stitch, down stitch, jam stitch, and joint stitch.

Finishing Defect

After pressing Garments there should be no crease mark, puckering. Keeping good appearance is also necessary for garments.

Packing Defect

There are zero tolerance any types of packing defect. Incorrect size, incorrect PO, incorrect quantity, folding defect include in packing defect. You should be careful about these defects.

Before final inspection, you can do pre-final or shadow inspection to see quality of your packed garments. If you found lots of defect in packed garments, you should re-check all garments and take effective measures to resolve the quality problem of garments.

Finally quality improvement is a continuous process that’s why you have to give your effort continuously and this will be possible through proper monitoring every steps of garments manufacturing. If you can ensure monitoring and take immediate action to resolve the defects then obviously you product quality will be improved.

Types of Garments Defects

Types of Garments Defects

You may find several types of garments defects in a production process. First of all, let have some idea of what basically defect is? Any variation from quality standard (QS) that affects appearance, durability, safety or fitness of a product is called a defect.

 garments defects

Defects are classified into following three categories

  1. Critical Defects
  2. Major Defects
  3. Minor Defect

Critical Defects: It refers that the product is unsafe or hazardous for the end user or violate mandatory regulations.

Major Defects: Major defects can result in the product visual or performance failure, reducing its marketability or usability. Because of this defect product cannot be sold as a 1st quality. If it is possible to repair or eliminate this defect then it will be possible to upgrade that product as a first quality.

Minor Defect: If a product has a minor defect then this type of product can be marketable and usable, but this will lose the standard quality. Because of this type of defects product fall short of defined specifications or quality standard.

Different Types of Garments Defects

  1. Construction Defects
  2. Color Defects
  3. Fabric Defects
  4. Trims Defects
  5. Packing Defects
  6. Measurement Defect

We can further classify garments defects into the following categories

Construction Defects

This defects created in garments manufacturing, actually occur at the time of product construction.

Color defects

Shading problem in garments contains a color defect. If there is wrong shade of color is applied on the product. The color defect is one kind of visual defect which can be the reason of reject of the product by the customers.

Fabric Defects

Garments are manufactured by using fabric. If there is any defect in the fabric then it will produce defected garments. That’s why fabric defect is sure will be visible in garments.

Trims Defect

Wrong trims and accessories considered as a trims defect.

Packing Defect

Packing is a very crucial and sensitive process for export garments. Choice of wrong packing materials may create defected package. On the other hand, wrong size packaging also considered as defected packaging. As because there are lots of defects found in packing, caution need to be taken when packaging.

Fit and Measurement Defect

You can’t make 100% accurate garments in maintaining measurement as buyer expectation. But there is a certain tolerance of measurement, you can’t cross that limit.

I have made a list of every category defect. See in the below.

Check the following list to get an idea of defects under different categories of garments defects

After crossing certain limit garments measurement, there will be a defect. There are defined measurement of all parts of garments. I have made an example of how measurement up down expressing:

– 1 1/4″ – 3/8″
 – 1 1/2″  – 5/8″
 – 1 3/4″  – 7/8″
 – 2″  – 1 1/8″
 – 2 1/4″  – 1 3/8″
 – 2 1/2″  – 1 5/8″
 – 2 3/4″  – 1 7/8″

 – MORE THAN 3″  – 2 3/8″
 + 1/4″  – 2 5/8″
 + 1/2″  – 2 7/8″
 + 3/4″  + 1/8″
 + 1″  + 3/8″
 + 1 1/4″  + 5/8″
