What is Lint (material)?
'''Lint''' is a collection of clothing fibers and other materials usually on or around clothing. ==Types== === Pocket lint === Pocket lint is lint in the bottom of [[pocket]]s. Pocket lint is usually made up of, but not limited to detached [[textile|fabric]], [[dust]] and paper scraps. In some contexts, pocket lint may also refer to random items in one's pocket.

Many people find that, at the beginning and end of the day, a small lump of fluff has appeared in the navel cavity. People have wondered why this happens for many years. In 2001, Dr. Karl Kruszelnicki of the [[University of Sydney]], [[Australia]], did a survey to find out why this happens.

The fibres move there from [[friction]] of body hair on underwear. * Women have less navel lint because of their finer and shorter body hairs. Older men have it more because of they have more hair and it is thicker. * Navel lint's color is usually [[blue]]-[[gray]]. The color is most likely an average of all clothing colors worn.<ref>{{cite web|url=http://www.feargod.net/fluff.html|title=The Incredible World of Navel Fluff|author=Graham Barker|work=Graham's Paddock|access-date=2011-05-27|archive-date=2004-10-09|archive-url=https:
