The “air dry flat” technique addresses wool’s inherent sensitivity to heat and its tendency to stretch when wet, ensuring the garment retains its original form and avoids damage.
The rationale behind air drying flat stems from wool’s unique properties. When wet, wool fibers relax and become more susceptible to stretching and distortion. Heat from a dryer exacerbates this, causing rapid shrinkage and potentially irreversible damage to the fibers. Hanging a wet wool garment can lead to misshaping due to the weight of the water pulling down on the relaxed fibers. Gravity, combined with the garment’s wet weight, can stretch the shoulders and sleeves, distorting the overall fit. For instance, a hand-knit wool sweater, if machine dried or hung to dry, can lose its intricate cable patterns and shrink significantly, becoming unwearable. Conversely, laying the sweater flat on a clean, dry surface allows it to dry naturally while retaining its original shape and dimensions. Similarly, a structured wool jacket, if hung to dry while wet, can lose its tailored silhouette. Air drying it flat preserves the jackets structured form and prevents stretching in vulnerable areas like the shoulders and arms.
Proper execution of the “air dry flat” technique involves laying the garment on a clean, dry, absorbent surface, such as a thick towel or a mesh drying rack. The garment should be reshaped gently to its original dimensions while damp. Avoid direct sunlight or heat sources, which can cause fading or shrinkage.

Reduced Water Repellency
Wool naturally possesses water-repellent properties due to lanolin, a protective wax secreted by sheep. Fabric softener coats wool fibers with a silicone-based film that inhibits lanolin’s function. This reduces the wool’s ability to repel water, making it more susceptible to staining and moisture damage. A wool coat treated with fabric softener, for instance, might absorb rainwater rather than shedding it, leading to dampness and potential damage to the garment.
-
Impaired Breathability
Wool’s breathability stems from its complex fiber structure, which allows air to circulate and regulate temperature. Fabric softener disrupts this natural process by coating the fibers and reducing airflow. This diminished breathability can lead to discomfort, particularly in warm or humid conditions. A wool sweater washed with fabric softener might feel less comfortable and more prone to overheating compared to one washed without it.
-
Fiber Build-Up and Reduced Loft
Repeated use of fabric softener can lead to a build-up of residue on wool fibers. This build-up can create a stiff, heavy feel and reduce the wool’s natural loft, which is essential for its insulating properties. A wool blanket repeatedly washed with fabric softener may lose its fluffiness and become less effective at trapping warmth.
