Turn Your Clothes Inside Out Before Washing Them
This is a simple but very effective laundry trick you can use to reduce pilling on the outside of your sweaters, shirts, blouses, skirts, and slacks where it would be most noticed. Pilling is caused by rubbing and friction as the individual fibers break or fray and then ball up. Although pilling tends to occur more frequently in synthetic fibers, it can occur to a lessor degree in natural fibers as well. The less friction generated against the surface of your materials, the less pilling they will accrue.When doing laundry, turning clothes inside out also helps prevent buttons, zippers, sequins, beads, embroidery, patches, lace, ties, bows, and other raised decorations on your materials from getting snagged. It will also help prevent small imperfections in materials that you may not have even noticed from snagging and/or pulling and becoming much larger problems. Belt loops, collars, and pockets are also less likely to snag and pull.
Wash Laundry On Delicate Cycle With Delicate Detergent
In general, liquid detergents are less abrasive on clothing than powders. If you do use powders, be absolutely sure to allow the powders to fully dissolve before loading your more delicate clothing because powders can be very abrasive (think about how Ajax cleans a sink!). Additionally, some liquid detergents, such as Woolite, are less harsh and will not fray your fibers that lead to pilling as much.
