Lint is composed of small fibers that break off clothing during laundering. The amount of lint produced depends upon the type of fabric being washed. Most fabric doesn't produce enough lint to cause problems in water disposal systems. Some fabrics such as polyester, acrylic and nylon have a tendency to unravel and ball up on the surface of the fabric. This is called pilling. Unlike pilling, lint does not adhere to the clothing and is easily brushed off with a lint brush or removed by relaundering the garment. Lint can become caught in pilling and make the pilling more obvious. Some fabrics attract lint.

Residue is often mistaken for lint. Residue is a white substance left on clothing after the wash cycle has finished. It is caused by overuse of detergent or fabric softener or by overloading the washer.

Low water pressure can increase lint. A decrease in pressure may be caused by kinks in the fill hoses or by sediment build up.
