Appl. No.:

10/577889

Inventors:

Wolfgang Greiser - Neusäβ, DE
Roger Souther - Woodruff SC, US
Bertrand Weiter - Bobingen, DE

Assignee:

Johns Manville - Denver CO

International Classification:

B32B 27/04
B32B 27/12

US Classification:

442 85, 442401, 442402, 442408, 2642884, 2642896, 264479

Abstract:

A polyester filament nonwoven ply is suitable for roofing and roof-sealing webs and has a latent shrinkage force which counteracts drafting forces which may subsequently occur as the result of stresses or during thermal processing operations. The roofing webs thus remain dimensionally stable even when exposed to heat. The shrinkage force is obtained according to the claimed process by drafting the ply accordingly in a drafting mechanism arranged after a dryer.

Abstract:

A flexible nonwoven mat of polymeric fibers is liquid water transmission resistant and is particularly well suited for use as a prefabricated building construction underlayment. The polymeric fibers may be standard polymeric fibers or sheathed polymeric fibers that have fiber sheaths with a lower softening point temperature than the softening point temperature of the fiber cores. Preferably, the polymeric fibers are spunbond fibers and are bonded together through the application of heat and pressure. Where the fibers are sheathed fibers, interstices of the nonwoven mat are at least partially filled by a portion of the polymeric material of the sheaths that is dispersed into the interstices to reduce the porosity of the mat. The polymeric fibers on at least one major surface of the mat may be coated with a hydrophobic binder coating material and/or a water repellant coating material to increase the liquid water impermeability of the mat and other coating materials may be applied to one or both major surfaces of the mat to provide the mat with additional or enhanced physical characteristics.

Abstract:

A flexible nonwoven mat of polymeric fibers is liquid water transmission resistant and is particularly well suited for use as a prefabricated building construction underlayment. The polymeric fibers may be standard polymeric fibers or sheathed polymeric fibers that have fiber sheaths with a lower softening point temperature than the softening point temperature of the fiber cores. Preferably, the polymeric fibers are spunbond fibers and are bonded together through the application of heat and pressure. Where the fibers are sheathed fibers, interstices of the nonwoven mat are at least partially filled by a portion of the polymeric material of the sheaths that is dispersed into the interstices to reduce the porosity of the mat. In certain embodiments, the polymeric fibers on the top major surface of the mat are coated with a hydrophobic binder coating material, which is overlaid with a water repellant coating material, such as a filled asphalt, modified bitumen, or a non-asphaltic polymeric film, to increase the liquid water impermeability and enhance other physical properties of the mat.
