It could be cashmere, wool, flannel, cotton, or even a synthetic fiber, but chances are, one of your favorite sweaters will eventually pill. Pilling occurs when groups of fibers break, tangle, and mat together, making the texture of the sweater rough and decidedly unattractive.
Fortunately, there are ways to prevent pilling, such as following the manufacturer’s care instructions, turning the garment inside out before washing, making sure to use the gentle cycle (and shorter washing-machine cycles in general), removing the garment from the dryer immediately, and brushing the sweater regularly with a lint or bristled garment brush. But if pills do appear, you can try one of the following techniques to remove them:
Remove the little balls, one pill at a time, using a small pair of scissors or a razor blade, being careful not to damage the fabric by cutting too close to the surface.
Or, you can purchase a sweater comb or electric fabric shaver, then drag it across the fabric to remove the pills. These battery-operated devices can also be used on furniture and blankets; they’re are available in various sizes and usually come with removable rings designed to protect delicate textiles. Just be sure that you aren’t wearing the garment while de-pilling it, and remember to empty the pill trap when it’s full.
