Loop fastening material for fastening device and method of making same.

摘要

The loop fastening material (20) is formed by a method comprising the steps of: providing a backing (22) of orientable material in its dimensionally unstable state; positioning a plurality of filaments (30) on the backing; securing the filaments to the backing at spaced, fixed regions (32) along each of the filaments, the fixed regions defining between each pair an unsecured catching region (34); and causing the orientable material to be transformed along its path of response to its dimensionally stable state thereby shirring the filaments at the catching regions to form fibrous elements (28) projecting from the backing between the fixed regions.
