Shrunken Uniforms and Bleeding Colour: A Self-Help Group's Quality Problem
A women's self-help group in Tiruppur has stitched 200 school uniforms from a single lot of cotton poplin. After the first wash, parents complain that the blue uniforms shrank about 4 cm in length and that the colour stained white socks. The group used a plain seam on the side with about 10 stitches per inch, left the elastic exposed at the waist, and attached a label saying 'wash as usual'. The fabric was cut and stitched without any pre-treatment. The school has threatened to cancel the balance order of 300 uniforms. The group has two weeks, limited money for testing, and access to a local testing lab that charges ₹600 per test. The tailor argues that shrinkage is 'normal for cotton' and that parents washed the uniforms wrongly.
1. Diagnose the causes of shrinkage and colour bleeding, and state what the group should do before cutting the next lot.
Read the worked answer
Shrinkage: cotton poplin shrinks because the fibres are stretched during weaving and finishing. If the fabric is cut without pre-treatment, the first wash releases that strain and the garment shortens. A 4 cm loss on a uniform is far beyond acceptable; the tailor's claim that it is 'normal' is only partly true - some shrinkage is normal, but it should be removed before cutting, not after stitching.
Colour bleeding: poor dye fastness or inadequate washing-off of unfixed dye at the mill. Dark blue transferring to white socks in the first wash indicates unacceptable colour fastness for a school uniform.
Before cutting the next lot:
- Pre-shrink the whole lot by soaking or washing in cold water, drying in shade, and pressing. Measure a 10 cm × 10 cm square before and after to calculate the shrinkage percentage.
- Add allowance to the pattern based on that measured percentage, not guesswork.
- Test colour fastness on a sample: rub with a damp white cloth and wash a sample with white cloth. The ₹600 test is worth it against a cancelled order of 300 uniforms.
- Reject or exchange the fabric if bleeding persists after washing; the supplier should be informed in writing.
Reasoning: these are fabric-level faults that cannot be fixed by better stitching. Acting before cutting protects both the balance order and the group's reputation.
2. Recommend construction changes for children's school uniforms, giving reasons for seam choice, stitch density, elastic and stress points.

Seam choice: use a flat-fell seam on the side and inseam, or a French seam on lightweight poplin. A plain seam with raw edges frays with repeated washing and is uncomfortable against skin. Flat-fell seams enclose the raw edges and are strong; French seams are neat and smooth for light fabric.
Stitch density: 12–14 stitches per inch is appropriate for cotton poplin. The present 10 per inch is too loose for a garment that will be washed frequently and worn by active children; it increases seam slippage. Use polyester-cotton thread for strength and colour matching.
Elastic: encase the waist elastic in a stitched casing with two rows of stitching, leaving a small opening for replacement. Exposed elastic curls, digs into the waist and frays at the edges. A drawstring or buttonhole adjustment helps different body sizes.
Stress points: backstitch or bar-tack at the crotch, pocket corners, placket ends and belt loops.
Fit and safety: avoid long dangling drawstrings at the neck for young children; use fixed loops or elastic. Allow ease for growth and movement.
Reasoning: children's wear fails at seams and waistbands first. Specifying construction at these points prevents returns more effectively than cosmetic finishing.
3. Draft a care label and a pre-delivery quality checklist for the group.

Care label (Tamil and English):
- Wash separately in cold water for the first wash
- Do not bleach
- Mild detergent; do not soak for long
- Dry in shade, inside out
- Warm iron; avoid ironing directly over elastic
- Wash dark colours separately
Pre-delivery checklist (sample 10% of each size):
- Measurements after pre-shrinking match the size chart; check length, chest, waist and sleeve.
- Seams are flat-fell or French, with no raw edges or puckering.
- Stitch density 12–14 per inch; stress points bar-tacked.
- Elastic casing secure and elastic not twisted; waist stretches and recovers.
- Colour fastness checked on a washed sample; no transfer to white cloth.
- Buttons, hooks and zips secure; no sharp edges or loose threads.
- Care label and size label attached securely and correctly.
- Garments pressed, folded and counted against the order.
Record keeping: note the fabric lot, pre-shrinkage percentage, test result and date. If a complaint arises, the group can trace it to a lot instead of guessing. Delivering 200 checked uniforms with a written record is a stronger answer to the school than a verbal promise.
