Drying
Drying
Drying tests how to remove water quickly and evenly without shrinkage, browning, bleeding, or distortion.
Core rules and concepts
- Aim to dry within 24-48 hours. Use airflow, dehumidification, and moderate temperature.
- Dry hand-knotted wool flat and supported; block to dimension and check measurements during drying.
- Cellulosic fibers (cotton, jute) are prone to browning with slow drying, alkaline residue, or poor rinsing. Rinse well and dry fast.
- Silk and rayon need quick, gentle drying; avoid direct heat and hanging wet, which distorts.
- Fringes dry flat, combed, and weighted if needed. Do not let metal touch wet wool.
- Tufted rugs dry face up or as the backing allows, with air under and over; never stack wet rugs.
- Monitor with a moisture meter and record. Drying begins immediately after rinsing; extraction removes only part of the water.
Worked example
After washing a hand-knotted wool rug, extract, dry flat on a rack, position air movers for cross-flow, run a dehumidifier, and check dimensions at 12 and 24 hours. Block to original size and comb the fringe. This prevents shrinkage and browning.
Traps
Drying in direct sun; using high heat; stacking wet rugs; and skipping moisture checks.
