Abstract
A method for quantitating the amount of lint shed from a paper towel including cleaning a rectangular deposition surface having a short dimension and a long dimension, wherein cleaning comprises spraying the entire surface with glass cleaner, using a substantially lint-free squeegee to push the glass cleaner off one of two short sides of the surface, and using a substantially lint-free sponge to wipe the edges of the surface substantially free of lint; preparing a sample of paper towel to be analyzed; depositing lint from the sample onto the cleaned surface by moving the sample thereupon in a specific pattern; collecting the lint deposited on the surface; and determining the amount of collected lint.
