Abstract
Abstract A napped bedding blanket having an enhanced hand and a more uniform surface appearance and which substantially avoids the problem of shedding and pilling without chemical treatment or mechanical locking and thereby is able to substantially maintain its initial surface appearance during normal usage and after laundering. The blanket has a nap of uniformly distributed raised fibers on at least one side of a fibrous substrate, with the fibers extending generally outwardly from the substrate a uniform distance to provide a planar surface on the nap. The blanket is produced by subjecting a nappable substrate to a napping operation to raise fibers from the substrate and form a nap, and thereafter shearing the nap to a level such that substantially all of the raised fibers are sheared.
