摘要 A debridement sponge made from a nonwoven fabric comprising, in a preferred form, yarn-like strands of bleached cotton fibers. In the preferred form, the strands are interconnected at multiple junctures to form fewer than 31 generally rectangular apertures per cm<2>. Moreover, each aperture has an area of 1.3 mm<2>. Furthermore, the fabric has a Calculated Strand Density of 0.17 g/cc, a Clarity Index of at least 0.75, and an Absorbent Capacity of at least 7 grams of a colored, aqueous, saline solution per gram of the fabric when compressed under a pressure of 3.3 g/cm<2>. Plug Harshness and Compression Recovery of the fabric are excellent. <IMAGE>
