摘要： A composite fuel filter material which comprises (A) a support layer made of wet laid cellulose and/or synthetic fibers, (B) a barrier layer having wet laid glass fibers for providing increased efficiency to the filter material, (C) a thermosetting bonding agent dispersed through the composite and in an amount sufficient for bonding the composite into a strong, tear resistant and pleatable material, and (D) a water repellant agent dispersed in the composite for removing and coalescing water dispersed in a fuel to be filtered. In a preferred embodiment for a diesel fuel filter, the glass fibers have an average diameter of about 0.1 to 2.0 microns and the thermosetting bonding agent is an epoxy resin in the composite in an amount of between 1 and 5% by weight. A filter efficiency of at least 90% or even 99% can be achieved, along with a water removal of 90 to 99.9%.

摘要： A vertically lapped material for acoustic applications includes a first layer of material constructed from at least one layer of non-woven textile fibers. The at least one layer of non-woven textile fibers is folded into a plurality of folds to form a pleated structure. A depth of the pleats of the pleated structure determines a thickness of the first layer of material. Furthermore, at least one second layer of material is connected to the at least one first layer of material. A method of assembling a carpet to form a carpet assembly includes the steps of providing the above at least one first layer of material and a heated carpet; inserting the at least one layer in a cold mold adjacent to the heated carpet; and molding the at least one layer with the heated carpet in the cold mold to form the carpet assembly. It is unnecessary for the at least one layer to be preheated or premolded before insertion into the cold mold.

摘要： There is provided an integral textile composite (1) which fabric comprises a substrate portion (2) having at least one organic textile fiber layer (3) and an insulating portion (6). The insulating portion (6) has at least one inorganic fiber layer (6a) which is substantially co-extensive with the organic fiber layer (3), and at least one insulating layer of insulating material (6b) which is substantially less than co-extensive with the inorganic fiber layer (6a). A plurality of first needled stitches (10) composed of organic fibers from said organic fiber layer (3) of said substrate portion (2) are needled in and disposed at least substantially through the insulating portion (6), while the inorganic fibers of the inorganic fiber layer (6a) in the insulating portion (6) are substantially undisturbed. The number of said stitches is sufficient that the insulating portion (6) is substantially non-detachable from the substrate portion (2) and the substrate portion (2) is essentially free on its outer surface (5) from inorganic fibers from the inorganic layer (6a) or insulating material from the insulating layer (6b) of the insulating portion.

摘要： An automotive panel includes a first layer having a fibrous portion. The first layer additionally includes an electrically conductive thread sewn into the fibrous portion. The sewn electrically conductive thread forms a circuit configured to deliver current from a power source. A second layer overlaps the first layer. At least one of the conductive thread or the fibrous portion includes materials having suitable properties to allow for die cutting or thermoforming the automotive panel without damaging the fibrous portion or disrupting the continuity of the circuit formed by the conductive thread.
