Abstract
A novel fabric-covered wall- or ceiling-board of improved abrasion resistance is disclosed. The fabric is composed of fibers of at least two different melting temperatures. The product is manufactured by heating the fabric to a temperature to soften one fiber but not the other and bonding the fabric to the board.
Claims4
A wallboard structure comprising a substantially rigid fiberboard base and a fibrous carpet material bonded to a surface of said fiberboard base, said carpet material being a non-woven felted fabric of interlocked bonded fibers composed of 2-15% relatively low melting fibers and 85-98% relatively high melting fibers, the high melting fibers having a melting temperature at least 10.degree. F. greater than the melting temperature of the low melting fibers, said high melting fibers being bonded at the contact points with said low melting fibers substantially throughout said fabric.
