Abstract
Silent touch fastener material adapted to releasably engage a mating surface and adapted to produce reduced sound during rapid separation of the touch fastener material from the mating surface. The material comprises a planar backing material having an engaging surface thereon contacting the backing material at discrete points and adapted to releasably engage the mating surface and means for reducing the coupling of noise-producing vibration from the backing material into the surrounding air. Various embodiments disclose the backing material as having a high mass relative to the mass of the engaging surface; a planar high mass supplemental backing material bonded to the backing material; a flexible, high mass material incorporated into the backing material; means disposed at the discrete points of attachment of the engaging surface to the backing material for suppressing the coupling of vibrations produced in the engaging surface into the backing material; and, the backing material comprising a lattice structure having low ability for transferring vibrations induced therein into the air surrounding it.
