ABSTRACT:
A layered composite batt consists of a plurality of layers, each layer having a series of overlapped, cross-laid webs of fibers. The fibers forming the webs, the webs, and the plurality of layers are bonded to one another to form the composite batt by a melted and resolidified copolymer. The process used in producing the composite batt comprises producing a plurality of open webbed fibers, dispensing particulate copolymer on to each open web of fibers, reciprocatively layering each web and the particulate copolymer carried therewith to form a layer having an upper and a lower face, arranging the layers thus formed such that each layer produced is in face to face contact with at least one other layer thereby forming a plurality of layers, and heating the plurality of layers to a temperature above the melting point of the copolymer but below the scorching point of the fibers. The apparatus used in producing the layered composite batt consists of a conveying means, a plurality of web producing means each for producing a web of fibers admixed with a copolymer, said conveying means and said plurality of web producing means being arranged such that each layer produced is in face to face contact with at least one other layer thereby forming a plurality of layers, and means for heating the plurality of layers to a temperature above the melting point of the copolymer but below the scorching point of the fibers.
