  • Patent number: 8500942
    Abstract: A method for forming a textile fusible sheet material includes producing a fibrous web from fibers on a laydown apparatus so as to form a backing ply and applying a mixture of a binder and a thermoplastic polymer to selected areal regions of the fibrous web. The method further includes thermally treating the fibrous web so as to dry and bond the fibers of the fibrous web using the binder to form a bonded fibrous web nonwoven fabric and so as to sinter the thermoplastic polymer with a surface of the bonded fibrous web nonwoven fabric.
    Type: Grant
    Filed: July 29, 2008
    Date of Patent: August 6, 2013

  • Publication number: 20130059114
    Abstract: A fusible interlining usable as a front fusible interlining in the textile industry includes a support layer including a weakly bonded and water jet-structured fiber web or nonwoven. The support layer is bonded in preselected areas by a binder and has an adhesive compound on at least one side. The support layer has a grid-like hole structure.

  • Patent number: 8114794
    Abstract: The invention relates to a nonwoven fabric which is bonded at selected points by use of a binder containing particles composed of filler material (a phase change material, among others) and which is not bonded at other selected points. The nonwoven fabric is characterized by a soft touch and good flexibility, and may be used as an interlining material or an intermediate layer.

  • Patent number: 6407019
    Abstract: A preform material for manufacturing a protective garment having a top material, in particular a firefighter's protective garment. The material is made of an insulating lining made up of an at least two-ply water-jet-consolidated nonwoven fabric having a weight per unit area of 80 g/m2 or lighter for each individual ply, a lining material having a weight per unit area of 120 g/m2 or lighter, that is quilted to the at least two-ply nonwoven fabric; and a semipermeable membrane, constituting a moisture barrier. After the at least two-ply water-jet-consolidated nonwoven fabric has been quilted to the lining material, the semipermeable membrane is laminated onto the outer side, facing away from the lining material, of the nonwoven fabric ply and has a weight per unit area of 20 to 30 g/m2.
