Fulling and Finishing
A shrinkage process to tighten the weave and improve the texture of a fabric. Moisture, heat and friction cause the fabric to shrink a controlled amount in length and width.
Woolen fabrics are brushed to pull fiber ends to the surface to create a "nap." Deep naps are produced by running the fabric over cylinders with fine metal wires and small hooks that pull out the ends of the fibers.
Worsted fabrics go through clear finishing where they are sheared or singed to give the fabric a smooth surface and crisp feel. Unfinished worsteds are lightly napped to have a woolen-like surface, this gives the fabric a soft woolen feel but the firmness of a worsted.
Decating finishing is a shrinking process that gives the fabric stability. The fabric is wound on a perforated cylinder and steam is passed through.
