Abstract
A napped fabric is treated to bond the nap fibers together while leaving the nap structure largely open and porous. The surface of the bonded nap is then subjected to a series of spaced short cuts to form spaced clumps of bonded fibers which clumps have free ends projecting from the bonded nap so that they can be brushed from stable upright positions to bent-over positions, giving an attractive rough appearance resembling a split suede leather.
