ABSTRACT:
A densified batt comprising a mixture of low melting and high melting synthetic fibers or high melting synthetic fibers coated with a low melting material formed by building up the fibers into a batt of unbonded fibers of substantial height, compressing the unbonded fibers to the extent that the batt has a height of at most one-third the height when not compressed, heating the compressed batt to bond the fibers together, and cooling the heated compressed batt while still compressed to provide the densified batt. The batting being in a single layer and uniform throughout can be readily fabricated into cushioning or the like having controlled characteristics.
