14 Main Tests and Quality Checkings in Clothing and Textiles Quality Inspection

The Most Common Quality Issues, That Buyers of Clothing and Textiles Must Be Aware Of?

First is some quality issues are due to the materials and accessories. and Second is some problems are due to the patterns or to the way the fabric was cut. A common temptation for factories is to reduce fabric consumption.

How to Avoid These Quality Issues?

  1. Work with a good cut & sew workshop. And make sure they don’t subcontract to a cheaper workshop.
  2. Don’t push them to rush production. If you have a firm delivery deadline, make sure all the samples’ approvals are done well in advance.
  3. Many buyers send an inspector once during the sewing process, and again after production is done. By catching issues and giving feedback to the sewing line leaders, this approach tends to improve quality. Pre-shipment inspections are the last time quality can be checked in China and are essential.

List of tests that can be done on-site inspection (in the factory):

  1. Counting the number of stitching points per inch/cm for the main stitching
  2. Checking the types of stitching, and the seam allowances
  3. Measuring the fabric weight, for the main fabric
  4. Comparing colours (of fabrics, accessories, and stitching threads) with a TPX or TCX Pantone book/lab dips/fabric swatches
  5. Checking seam strength, by pulling in both sides with normal force
  6. Checking the strength of stitches for all accessories (buttons, bows…)
  7. Checking the dry colourfastness, by rubbing a piece of white tissue/cotton fabric
  8. For certain accessories such as fabric flowers: checking the friability at edges
  9. Doing a fitting test, to checking fitting but also to see the overall outlook
  10. Making sure the lining is never longer than the self-fabric and is not visible during fitting tests
  11. Making sure the products look good and have no wrinkles when presented on a hanger
  12. Making sure the products are as flat as possible in cartons and the foam parts (if applicable) don’t get crushed
  13. Making sure there is no colour shading on the same product and no strong colour shading between different products
  14. Taking very clear photos of the care & content label (composition, care instructions, country of origin…)

And the common checkpoints:

  • a. Appearance:

do they look good as presented at point of sale, when unpacked, and when worn? Are colours and fabrics the same as approved?

  • b. Conformity of workmanship:

Is production conform to approved pre-production samples?

  • c. Construction:

Are the stitchings strong, will the garments survive normal wear & tear for a little while, etc.

  • d. Measurements:

Will the fitting be good, in each size?

  • e. Finishing:

Are the garments ready to be sold, or need further work?

  • g. Packing and labelling:

Is it conform to the buyer’s requirements?

Depending on the type of clothing and textiles product and the market of the importer, many other tests can be inserted in the inspector’s checklist:

  • Checking the direction of threads (the “grainline”) of the main fabric, compared with client’s sample or client’s pattern
  • Measuring the stretchability of fabrics and elastics, compared with client’s sample or specs
  • Counting the number of threads (i.e. the construction of the fabric)
  • Doing a shrinkage test, after normal cycle washing and natural drying
  • Checking colourfastness to washing, by washing a sample with normal cycle together with a piece of white cotton fabric
  • If there are strings that could cause strangulation: measuring the length of strings
  • For some textile products such as underwear, measuring the height of the garment on the hanger (because of shelf space and outlook consistency).

What sort of product information must the buyer provide to the Inspection company?

Many professional importers provide a “tech pack” that includes:

  • Types of fabrics and accessories (in detail)
  • All labels
  • Size charts
  • Comments about successively reviewed samples (this is useful because the same issues might be found in production)

And they usually have a packing manual that provides general rules about the size of cartons, shipping marks, polybags, folding way, and so on.

For a small company that starts to purchase garments, this is not a super-human effort as long as they have a template for inspiration.
