US Classification:

442/411000, 442/402000, 442/409000, 264/402000, 264/503000

Abstract:

A method is disclosed of controlling the thermohysteresis of a homogeneous or layered fibrous pre-form, comprised at least in part of thermoplastic staple length fibers, such that the physical properties of the resulting molded three-dimensional compound construct are significantly enhanced. In particular, the thermohysteresis is the result of a specific thermal history comprising the treatment of a fibrous pre-form with an elevated temperature incubation period followed by a cooling period. A so-treated fibrous pre-form can be subsequently molded by conventional thermomolding methods to render improved toughness, strength and structural stability to a resulting molded construct.

US Classification:

442/401000, 442/340000, 442/361000, 442/400000, 442/394000, 442/409000

Abstract:

The present invention is directed to a protective outdoor fabric comprising one or more layers of fine denier spunbond filaments and at least one layer of barrier material, wherein said protective outdoor fabric has a significant barrier performance as measured by the hydrostatic head to barrier layer basis weight ratio being of about at least 4.9 cm/gsm. In the preferred practice of the present invention, first and second outer fabric layers are formed, each comprising continuous filament spunbond layers of thermoplastic fibers, with the size of the continuous filaments between about 0.7 and 1.2 denier, preferably less than or equal to 1 denier. The barrier layer preferentially comprises microfibers of finite length, wherein the average fiber diameter is in the range of about 1 micron to about 10 microns, and preferably between about 1 micron and 5 microns, said layers being consolidated into a composite fabric.

Abstract:

The present invention is directed to a nonwoven composite fabric for use on batteries or fuel cells comprising one or more layers of fine denier spunbond filaments and at least one layer of barrier material, wherein said nonwoven composite fabric has an improved barrier performance as measured by an increase in the hydrostatic head to barrier layer basis weight ratio. In the present invention, a first fine denier layer is formed, comprising continuous spunbond thermoplastic filaments, with the size of the continuous filaments between about 0.7 and 1.2 denier, preferably less than or equal to 1 denier. A barrier layer is deposited onto the first fine denier layer. The barrier layer preferentially comprises microfibers of finite length, wherein the average fiber diameter is in the range of about 1 micron to about 10 microns, and preferably between about 1 micron and 5 microns, said layers being consolidated into a composite fabric.

International Classification:

B32B003/00

US Classification:

428156000

Abstract:

The present invention is directed to a method of making a nonwoven cleaning article, which exhibits a plurality of three-dimensional images whereby the fabric is comprised of at least a first and second three-dimensional image that are dissimilar from one another. The three-dimensional images may be imparted into the fabric in a co-planar arrangement, multi-planar arrangement, or by utilizing both arrangements within the same fabric. Further, the present invention contemplates a cleaning article comprised of a plurality of three-dimensional images which can provide the fabric with various physical and/or aesthetic performances.
