Six Unlabelled Garments and a Burn Test
A boutique sends six unlabelled garments for wash-and-fold with a note: 'all gentle, lowest cost'. The lot is a shiny, stiff saree said to be pure silk with a metallic border; a soft, very fluffy shawl sold as pashmina; a dark stretch denim jacket; a printed scarf; a white cotton shirt with a fused collar; and a knitted pullover. You pull a spare yarn from an inside seam of each and run a burn test. The saree yarn smells of burnt hair and leaves a crushable black bead; the shawl yarn shrinks away from the flame, smells of burning plastic and leaves a hard black bead; the scarf burns like paper with a yellow flame and fine grey ash; the denim yarn also burns like paper but leaves a darker ash; the pullover yarn melts and drips. The boutique is a good repeat customer and wants the lowest possible bill.
1. Interpret the burn results, state their limitations, and explain how you would confirm the shawl and the scarf before advising the boutique.

Burn results are a screening test, not a fibre certificate.
- Saree: burnt-hair smell and a crushable bead point to a protein fibre, silk or wool. Silk is the likely claim, but a stiff handle can also come from sizing or from metallic weighting, so confirm by looking at a filament under a microscope: silk is a smooth continuous filament without the scales seen on wool. Check the metallic border separately.
- Shawl: melting, plastic smell and a hard black bead indicate a synthetic, most likely acrylic. Pashmina is cashmere, a protein fibre, and would smell of burnt hair and leave a crushable bead. This is the most important finding: the garment is not what it was sold as.
- Scarf: paper-like burn and fine grey ash indicate a cellulose fibre, cotton or viscose. Confirm by a wet-strength check: viscose loses a large part of its strength when wet and feels cool and soft, while cotton is stronger wet. A microscope showing a serrated viscose cross-section settles it.
- Denim: cellulose burn is consistent with cotton, and elastane in a stretch denim may not show in a single yarn.
- Pullover: melting and dripping suggests polyester or a similar synthetic.
Limitations: blends show mixed behaviour, dyes and finishes can mask smell, and the test destroys yarn. Confirm with a second method, and test each component separately, including sewing thread and trims. Record results on the job card before any cleaning.
2. Sort the six garments into cleaning routes and justify each route in terms of fibre, construction and risk.

Lowest cost is not the same as lowest risk; the boutique must be told where the two conflict.
- Silk saree with metallic border: dry clean. Water can water-spot silk, bleed the dye and tarnish the zari, and the border cannot be replaced. If the boutique insists on washing, use cold water with neutral detergent, no wringing, shaded flat dry, and record that the risk was accepted.
- Acrylic shawl: hand wash at 30 °C with mild detergent, no wringing, no tumble drying, cool iron only if needed. Acrylic can be dry cleaned, but washing is cheaper and safe if agitation is controlled. Inform the boutique that it is acrylic, not pashmina.
- Stretch denim jacket: machine wash inside out at 30–40 °C with similar colours, mild detergent, no chlorine; hang dry. Check metal trims and the stretch component before deciding on heat.
- Printed viscose scarf: hand wash cool, short soak, no wringing, dry flat in shade. Test the print for colour bleed first. Viscose loses strength when wet, so a machine spin can distort it.
- White cotton shirt with fused collar: machine wash at 40 °C, but avoid hot water and tumble drying, which can bubble the fused interlining. Check the collar before and after.
- Knitted pullover: hand wash or gentle cycle in a mesh bag, low spin, dry flat; do not hang, because the weight will stretch it.
Separate the loads by colour and fibre, and price the job by the handling each garment actually needs rather than by a single flat rate.
3. The boutique asks you to sew in labels saying 'dry clean only' on everything 'to be safe'. Advise them, and propose correct label content for the six garments.
Read the worked answer
A care label is a promise about a safe process, not a legal shield. Labelling everything 'dry clean only' is misleading and can create a different liability.
- Why blanket 'dry clean only' is wrong. It tells the consumer nothing about fibre content, and it may be false for acrylic and cotton items that are safely washable. If a customer later washes a cotton shirt labelled dry clean only, the label has caused unnecessary cost, not protection. A label must reflect the most restrictive process you can actually guarantee for that garment.
- Fibre content matters more than the symbol. Calling acrylic 'pashmina' or silk 'pure silk' without confirmation is a consumer-protection risk, independent of cleaning instructions.
- Proposed labels:
- Silk saree: 'Dry clean only. Do not bleach. Cool iron on reverse.'
- Acrylic shawl: 'Hand wash cold. Do not tumble dry. Dry flat. Cool iron.'
- Denim jacket: 'Machine wash 30 °C with similar colours. Do not bleach. Hang dry.'
- Viscose scarf: 'Hand wash cold. Do not wring. Dry flat in shade. Cool iron on reverse.'
- Cotton shirt: 'Machine wash 40 °C. Do not bleach. Warm iron. Do not tumble dry.'
- Knitted pullover: 'Hand wash cold. Dry flat. Do not tumble dry.'
- Process. Test before labelling, keep a copy of the label on the job card, and advise the boutique to obtain fibre confirmation from its supplier rather than guessing from handle or price.
