Fig. 2.

Total number of fibers released from 100 cm² of fabric per wash, using new and repolished (worn) fabrics: five polyester (PET) fabrics of differing structure, acrylic (A1) and nylon (N1). Results are presented in box plots showing median, 25th, and 75th percentiles, max and min. Results are presented together in final graph for easier comparison; letters indicating fabric type correspond to the previous graphs in this figure and to Table 1. Size 1 = 0.025 mm–0.25 mm, size 2 = 0.25 mm–1 mm, size 3 = 1 mm–1.75 mm, size 4 = 1.75 mm–3 mm, size 5 = >3 mm. Statistically significant differences between washes for each fabric are indicated by (*p < 0.05); n = 12; y axes differ in scale
