Stitching quality on home textiles is checked by measuring stitches per inch, seam allowance and hem width, then inspecting every seam for loose threads, skipped stitches and thread colour match. For bedding the stitch density is usually 8 to 12 stitches per inch, and a lower count tends to open up after a few domestic washes. Most of these checks need only a ruler, a stitch counter and good light, so an inspector can run them at the stitching unit before the goods are packed.
Stitching is where good fabric is most often let down. Mills around Ahmedabad, Surat and Kutch weave and process a wide range of cloth, but cutting and sewing are usually done in separate units, sometimes by subcontractors the exporter does not name. If nobody visits the stitching unit, the first time you see its work is when the cartons are opened in your warehouse.
What to measure on every seam
- Stitches per inch: count over a 1 inch length on hems and seams, usually 8 to 12 for bedding, and compare with the approved sample.
- Seam allowance: check that enough fabric is turned into the seam that it will not fray open under tension.
- Hem width and evenness: measure at several points along each hem; a hem that wanders is a sign of a rushed line.
- Thread colour match: the thread should match the fabric or the agreed contrast shade on both the face and the back.
- Loose threads and skipped stitches: look along the stitch line for gaps, and check that thread ends have been trimmed.
- Bar tacks: these should reinforce stress points such as zip ends, corner seams and the ends of elastic.
Checks that depend on the product
On fitted sheets the elastic tension matters more than anything else. The elastic should pull the corner in evenly without puckering the fabric, and should not be so slack that the sheet slides off a mattress at the top of the stated depth range. Stretch the corner by hand and let it go a few times; it should recover its shape.
On duvet covers and cushion covers, open and close every zip several times. The slider should run freely, the zip tape should be stitched straight, and any zip flap in the specification should actually cover the zip. On table linen, mitred corners should lie flat with the diagonal seam straight and no bulk at the point, and the hem width should match on all four sides.
How to organise the inspection
Agree the sample size and acceptance level with the exporter before production starts, so that there is no argument later about what counts as a failure. A standard statistical sampling plan with a tighter level for major defects is the usual approach on home textiles. Inspect once when roughly a fifth of the order is stitched, when problems can still be corrected on the line, and again when the goods are finished and packed.
Record each finding with a photograph and the measured value, not just a pass or fail. A written report with measurements is far easier to use in a claim, and it also tells the stitching unit exactly what to change.
What Creston & Co does
We visit the stitching unit as well as the mill, because the unit that sews your order is usually not the company that signed the contract. We run measurement and stitching checks during production and again before loading, and we send sealed samples to an NABL-accredited lab when a test is needed. If you want a second pair of eyes on an order, we offer a free 20-minute sourcing review.
