Why do sheets get fuzzy balls?
the thread the sheets were woven from, the weave the sheets were woven in, fiber content, the finishing the manufacturer used on the sheets, and various and assorted contacts between the sheets and the bodies that sleep on them. Textiles, in general, are made of various types of fiber. In general, the longer the fiber and the tighter the twist, the more stable the “yarn” or “thread” spun from them. The less brittle the fiber, the less breakage will occur. Cotton is a soft fiber, but some cottons are very long-fibered–“Pima cotton,” for example. Cotton fibers are frequently mixed with polyesters for ease of laundering, shrinkage control, and strength. For fabrics, in general, the tighter the weave, the more stable the fabric. For sheets, high quality sheets advertise their “Thread count” on the packaging–basically, how many warp and woof threads (these run at 45 degree angle from each other) the sheet has in a square inch of fabric. 180 is common, 220 or 240 is excellent. “Finishing”
