Curtains That Shrank in the Hotel Laundry
A 24-room boutique hotel near Kaziranga orders 48 curtain panels, two per window, in a 100% cotton slub fabric 140 cm wide at Rs 420 per metre, with a declared residual shrinkage of 8% in warp and 4% in weft after the first wash at 60 degree C. Each window takes four fabric widths to give the specified 2.5 times fullness on a 1.80 m wide window, and a finished drop of 2.10 m from the rod to the hem, made up of an 8 cm header and a 10 cm double hem. The supplier cuts each panel 2.28 m long, which is 2.10 m plus allowances, with no shrinkage allowance. The hotel's laundry washes all curtains at 60 degree C within a month of installation. The drops come back at 2.02 m, the hems sit about 8 cm above the floor, and the three panels on the south facade show fading and a powdery feel along the fold line. The hotel withholds the final 40% payment and demands replacement.

What happened. A 2.28 m cut shrinking to 2.02 m is an 11.4% loss, more than the 8% declared - so two faults sit side by side. First, the supplier cut with no shrinkage allowance at all, treating the finished drop as the cut length; that is a specification error and the supplier's responsibility. Second, the actual shrinkage exceeded the declared 8%, which is the mill's or the fabric's responsibility. If the care label says 40 degree C and the hotel washed at 60 degree C, the hotel's laundry practice contributes to the excess and weakens its claim for the portion above 8%.
Correct cutting length. Shrinkage applies to the whole panel, allowances included. Finished make-up length = 2.10 m drop + 0.08 m header + 0.10 m hem = 2.28 m. Cut length = 2.28 / 0.92 = 2.48 m. The supplier was 20 cm short on every panel.
Where the allowance belongs. Along the warp only - the 8% figure applies to length; adding 8% to the panel width would destroy the fullness calculation. Also check the lining and any interlining separately, since they shrink differently and will pull the face fabric.
Apportionment. The hotel should not lose the whole order, but neither should the supplier absorb the excess above 8%. Remake the drops to 2.48 m and split the cost of the excess shrinkage with the mill, supported by a wash test on retained samples.
2. Compute the fabric and cost for remaking all 48 panels, and propose changes for the sun-facing rooms.

Panel make-up. Four fabric widths per window across two panels means two widths per panel.
Fabric per panel. 2 widths x 2.48 m cut length = 4.96 m. Add 8% for pattern matching at the seams, squaring off and cutting loss: 4.96 x 1.08 = 5.36 m.
Whole order. 48 x 5.36 = 257 m, at Rs 420 = Rs 1,07,940. Add lining, stitching and re-hanging labour separately; the fabric alone is roughly Rs 1.08 lakh, against a withheld balance that should be checked first - if the 40% withheld is smaller than the remake cost, negotiate rather than absorb.
Sun-facing rooms. The powdery feel and fading are photodegradation of cotton plus alkaline detergent and heat along the fold, not a dye fault. Options: (1) a solution-dyed polyester or acrylic face cloth with a cotton-look slub, which holds colour in UV; (2) keep cotton but add a UV-stable blackout or dim-out lining and a pelmet to shade the top; (3) move to a tighter weave with a higher light-fastness rating and specify it in the purchase order. Do not simply re-order the same base cloth for the south side - it will fail again within a season.
Also verify that the fabric was pre-shrunk or compacted before cutting; if not, cutting 2.48 m will still be gambling on the mill's 8%.
3. Write the care label and installation advice that should have accompanied this order, and explain how each item prevents a repeat.

Care label. "100% cotton face, polyester/cotton lining. Machine wash 40 degree C, gentle cycle, mild detergent, no bleach. Do not tumble dry. Line dry in shade, hang while damp. Warm iron on reverse. Wash before first hanging."
Why each item matters. The 40 degree C limit caps thermal shrinkage and keeps the wash within the conditions the 8% declaration was tested at, so any excess shrinkage becomes a fabric fault rather than a laundry fault. Mild detergent without bleach protects the dye and the fibre; the powdery feel on the south panels is consistent with alkaline attack plus UV, and bleach accelerates it. No tumble drying removes a second, uncontrolled shrinkage and creasing step. Drying in shade limits UV exposure and photodegradation.
Installation advice. Wash the panels once before hanging, or hang them 2–3 cm long and let the first wash settle them; set the rod and hem allowance so a 2% settle does not lift the hem off the floor; use a dim-out lining and pelmet on south and west windows; and record the fabric's shrinkage test report with the room inventory so the next re-order repeats the same compaction.
Commercial point. Attach the label and the wash-test report to the invoice. The supplier then has documented evidence that the hotel's 60 degree C wash exceeded the care instructions, which is exactly the evidence needed to settle the withheld payment instead of remaking all 48 panels.
