1. The handle is tight and not loose. When the wool is spinning, the woolen manufacturer makes the wool yarn feel soft, and the twist of the spinning yarn is relaxed, so that the inter-fiber entanglement is relatively loose. It slips out and forms a small ball. As long as the twist is tighter, there is less pilling, but the sweater feels harder.
2. Some thickness is thin. Thin sweaters are mostly flat-knit single jerseys, with loose loop density and easy pilling. The thicker ones are mostly idling, the needle loop density is tight, and the fibers are tightly entangled. After the yarn is conflicted, the fiber slips from the yarn relatively little, and it is not easy to pilling.
3. To reduce pilling, try to avoid conflicts with rough-looking objects. Some parts where there are more conflicts, such as sleeves and desks, sofa armrests, inner pockets, wallets, etc., as well as long-term backpacks, wearing rough coats without lining, especially pilling, should be minimized.
4. For some of the less exposed pillings, you can use your fingers to pull it out quietly or use small scissors to cut it off, and use a clothes brush to smooth the hair. For larger areas with more pillings, you can first Spread the sweater flat on a flat table, use a brush to brush the dust on the stitches of the fabric, straighten it and tighten it, use a special electric shaver to quietly and straighten it, shave the ball, and clean it with a brush. Use a steam iron to iron it again, and it will look as good as new immediately without damaging the sweater at all.
