Abstract
A compressible resilient fabric can include a ground layer of knitted yarn, and a loop layer comprising a plurality of loops of yarn, each loop having a point knit into the ground layer. The fabric can be compressible from an non-compressed configuration, in which each loop has an apex extending substantially perpendicularly outward from the ground layer, into a compressed configuration, in which each loop is collapsed onto the ground layer. The fabric can further be resilient so as to substantially resume the non-compressed configuration when compression is relieved. The loop layer yarn can include a multifilament yarn having a high denier per filament ratio. The ground layer yarn can include a yarn shrinkable substantially more than the loop layer yarn. The loops can be densely knit so as to support the extension of the loops outward from the ground layer.
