Abstract: A glow-resistant batt of fibers; a copolymer of vinyl chloride and vinylidene chloride; and boric acid; and processes for producing such.

Abstract: A process for producing a fibrous batt by forming a thin web of fibers and then contacting the web with particles of a copolymer of vinyl chloride and vinylidene chloride; subsequently forming the web into a batt and then heating the batt.

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.

Abstract: A process for producing a polyester batt by forming a thin web of polyester fibers and then contacting the web with particles of a copolymer of vinyl chloride and vinylidene chloride; subsequently forming the web into a batt and then heating the batt.
