Defects in Garments Article


There are faults across all areas of the apparel manufacturing industry and Quality Control, in essence, is to stop these faults because faults, no matter what size, cost money. So it is important to recognise the different types of common faults in order to then be able to set up an effective Quality Control System.
The article explains the different types of defects found when sewing garments. It begins with a brief overview of why and where quality needs to be maintained, then elaborates with the different areas in which quality can be commonly affected. These are:
• Sewing defects
• Colour defects - in relation to specifications
• Sizing defects - grading, measuring, etc
• Garment defects - manufacturing

Then lists garment defects:

• Broken snaps
• Broken Buttons
• Broken stitching
• Defective snaps
• Different shades within the same garment
• Dropped stitches
• Exposed notches
• Exposed raw edges
• Fabric defects
• Holes
• Inoperative zipper
• Loose / hanging sewing threads
• Misaligned buttons and holes
• Missing buttons
• Needle cuts / chews
• Open seams
• Pulled / loose yarn
• Stain
• Unfinished buttonhole
• Zipper too short

There are details about different types of faults within these categories, with particular note to denim products and how to recognise the different faults such as re-stitching and frayed edges. Reference is given to denim products in particular due to the large amount produced worldwide and therein the consistency of the faults. There are also tips as to how to avoid these when sewing, complete with diagrams.
In conclusion, the article sums up again why Quality is important. Namely, to build up a company reputation and customer base, to produce high sales and an overall profitable business. The quality of the product determines its value and sets standards to measure things like the sales, service and pricing.

Quality Control of Finished Garments

We have extracted 2 chapters from different written sources which explain in clear detail the Quality Control process of inspecting finished garments, and a comprehensive list of defects found in every stage of the manufacturing process - Sewing, Seaming, Assembly, and Pressing/ Finishing.

The quality check on the garment depends on the cost of the garment. the higher the quality of the garment, the more stringent the quality inspection. the article gives tips as to how to improve analysis process when doing a test fit. It is important to check sizing and fit before a garment is dispatched, as inconsistent sizing can affect customer's loyalty.

Checking sizing and fit is only the first step, there are other areas to be inspected. Explicit instructions for these should be listed, including sewing operations with stitch types and pressing requirements such as crease sharpness. Rejects are to be classified in 3 categories: First Quality, Second Quality and Irregular.Other categories can be included, according to company policy.

Efficiency of the quality can depend on the number of rejects. For a line to be deemed efficient, defects must not exceed 0.5%.
