Washing wool in a machine often leads to shrinkage and felting. The agitation, combined with heat and moisture, causes the wool fibers to intertwine and mat together, resulting in a smaller, denser fabric. This process is irreversible and can significantly alter the garment’s size, shape, and texture. For example, a knitted sweater might shrink several sizes and become thick and stiff.
Understanding the effects of machine washing on wool is crucial for proper garment care. Historically, wool has been a valued textile for its warmth and durability. Preserving these qualities requires gentle handling. While modern washing machines offer delicate cycles, the risk of damage to wool remains. Avoiding this damage prolongs the lifespan of woolen garments and maintains their appearance.
