A Longitudinal Empirical Study Into the Buildup of Fluff in My Belly Button

Clothing businesses have given considerable attention to the way in which clothes “feel” on the body (Sun, Fan, Wu, Wu, & Wan, 2013). They invest hugely into developing fabrics that are cheap yet still provide a high-quality finish that will give consumers a sense of pride in wearing the garment (Farzandi, Razipour, Mousazadegan, & Saharkhiz, 2013). Such an approach is undermined when the fabric frays, is too abrasive, or molts. A key indicator of clothing molting is the buildup of lint in wearers’ navels (Steinhauser, 2009). Accordingly, the phenomenon of the buildup of navel lint is attracting increasing levels of research and an understanding of the factors influencing its sedimentation is emerging. A review of the material engineering, clothing and fabric sciences, human biology, and nanofiber literatures reveals that there are two gaps in our knowledge. First, no one has conducted longitudinal studies of navel lint deposition. All studies published to date are cross-sectional providing limited insight into its sedimentation. Second, a similar review reveals that the author’s own navel lint has never been studied in a rigorous or scientific manner. This study addresses these two gaps with a longitudinal empirical study of the buildup of my navel lint. Taking note of previous criticisms (e.g., Steinhauser, 2009), air pressure, temperature, and humidity were controlled for, and new and old garments were employed. To give confidence that the differing garments were the prime causal factors (T. Albert, 1984, cited in
