    Abstract: A three dimensional woven preform, a fiber reinforced composite incorporating the preform, and methods of making thereof are disclosed. The woven preform includes one or more layers of a warp steered fabric. A portion of the warp steered fabric is compressed into a mold to form an upstanding leg. The preform includes the upstanding leg and a joggle in a body portion. The body portion and upstanding leg are integrally woven so there is continuous fiber across the preform. A portion of the warp steered fabric includes stretch broken carbon fibers in the warp direction, and another portion includes conventional carbon fibers. The warp steered fabric can be woven on a loom equipped with a differential take-up mechanism. The warp steered fabric can be a single or multilayer fabric. The preform or the composite can be a portion of an aircraft window frame.

    Abstract: Crimp-imbalanced protective fabric is accomplished by varying the levels of yarn crimp within and across a layer or layers of a multi-layer fabric armor system. The method includes developing a crimp in the yarn (utilized for producing a fiber layer) by pulling the yarn through a solution that substantially coats the yarn. The removable coating has a thickness that ensures a proper amount of crimp in the yarn. The tension in the yarn is controlled; the yarn is weaved; and a crimp is applied in the yarn. Once the crimp is applied, families of the crimped yarn are utilized as a layer or layered to produce a soft armor form.

  • Patent number: 5387454
    Abstract: To make a velour needle felt, an optionally pre-needled staple fiber non-woven web is applied to a revolving brushlike support and is then needled to form a pile on the side which faces the support. To increase the resistance of the velour needle felt to distortion, it is proposed that a layer which has a higher resistance to distortion than the staple fiber non-woven web and consists particularly of a spun-bonded web is applied to the brushlike support before the staple fiber non-woven web is applied thereto and that the pile fibers are pulled in the needling operation through the layer which has the higher resistance to distortion.

  • Patent number: 5361466
    Abstract: A synthetic microfiber blanket having a uniform thickness is formed from a nonuniform blanket having thin or feathered lateral edges. The nonuniform blanket is cut transversely into a plurality of discrete pieces of blanket of uniform length. The plurality of discrete pieces of blanket are arranged with the thin lateral edges in overlapping relationship to form a blanket of a desired width and thickness. The overlapped, discrete pieces of blanket are then joined into an integral blanket of uniform width and thickness by entangling together fibers of adjacent pieces of blanket. A scrim backing can be incorporated into the blanket for added strength and dimensional stability.

  • Patent number: 5189769
    Abstract: A method of making a multi-layer non-woven multiple biased fabric is disclosed. A layer of fabric is directed in a longitudinal direction of travel, wherein the layer of fabric is comprised of a plurality of structural fibers oriented substantially parallel to each other and oriented at an angle to the longitudinal center line of the fabric. The layer of fabric may or may not be previously biased. If not previously biased, then the structural yarns of the fabric are biased in a biasing stage to form a layer of single bias structural fabric having the structural fibers biased to the fabric centerline. The single biased fabric layer is led into at least one folding stage for folding the biased layer longitudinally from one edge toward another to form a multiple biased fabric. The multiple biased fabric is led from the at least one folding stage into an affixing stage for affixing the multiple biased fabric together to provide a single structural fabric being multiple biased.

  • Patent number: 5164249
    Abstract: A multi-layered paper machine fabric having a preselected permeability value, comprising a single system of warp yarns and a multiple layers of weft yarns. The weft yarns include support surface weft yarns intermediate layer weft yarns and lower surface weft yarns all interwoven with the single system of warp yarns. The surface layer weft yarns are of a first thickness, the lower layer weft yarns are of a second thickness, and the intermediate layer of weft yarns are of a third thickness which differs from the first and second thicknesses. Certain ones of the support surface weft yarns are interwoven with the warp yarns to be vertically aligned with the lower surface weft yarns to form drainage channels therebetween. Certain of the intermediate weft yarns are interwoven with the warp yarns to be located intermediate of the surface weft yarns and the lower weft yarns and centrally of the drainage channels.

  • Patent number: 4690084
    Abstract: A lightweight embroidered puffed design fabric (10) having puffed design elements (E) formed in a prescribed embroidered design (C) is disclosed. The design fabric includes a front fabric (A) on which the design is formed and a lightweight back fabric (B). The front and back fabrics are united by embroidery stitching (14) which forms a preshrink design pattern D for the puffed elements. Back fabric (B) is a gauze-type fabric which includes a relatively low count of highly shrinkable cotton weft and warp yarns (22, 24) loosely woven to form an open mesh 20 to facilitate full and uniform shrinking of the back fabric relative to said front fabric. Excess in the face of the front fabric forms puffed design elements (30, 32) in a manner controlled by preshrink design pattern D. In accordance with the method, front and back fabrics are united in composite fabric (11) by embroidering preshrink embroidered pattern (D) on front fabric (A).

  • Patent number: 4642261
    Abstract: A two-face, double-layer forming fabric having a tight bottom weft geometry. The fabric, in general, comprises first and second pluralities of cross-machine direction yarns and a plurality of machine direction yarns interwoven in accordance with a desired weave pattern to define a top layer and a bottom layer. The top layer, which receives paper stock, is defined by the first plurality of cross-machine direction yarns. The bottom layer, which contacts machine rolls, is defined by the second plurality of cross-machine direction yarns. The second plurality of yarns are heat shrinkable.In one embodiment of the fabric, all machine direction yarns are woven in an 8-shaft weave to provide a 1/3 twill on the top layer and a 1/7 twill on the bottom layer. The cross-machine direction floats formed by this weave pattern are flattened during heat treatment of the fabric because of shrinkage of the bottom layer cross-machine direction yarns.

  • Patent number: 4224372
    Abstract: The disclosure is of a fabric adapted as clothing for a papermaking machine. The fabric, which may be made endless, is useful to make dryer felts, wet felts and forming wires. The fabric of the invention comprises a plurality of crosswise yarns disposed in a plurality of separate layers, each layer being on a plane parallel to the crosswise plane of the fabric. A plurality of lengthwise yarns is interwoven with the crosswise yarns and binds the layers of crosswise yarns together to form a multilayer fabric. Structurally, the crosswise yarns in a given layer are separated from the adjacent crosswise yarns in adjacent layers at points along their length by void spaces within the body of the woven fabric. A synthetic, polymeric, thermoplastic resin foam fills, at least partially, the void spaces to control the void volume in the fabric of the invention.

  • Patent number: 4179776
    Abstract: An improved method for producing and processing deregistered and disorientated synthetic tow for forming fiber filled articles in which crimped registered tow is deregistered through pairs of rolls utilizing a non-continuous groove-threaded surface. The synthetic tow is dispersed and spread, and collected for continuous distribution into and envelopment by article surface material. The automatic process and apparatus associated therewith additionally form and finish the fiber filled articles themselves for additional fabrication processes or for use as is. Vacuum suction and reciprocating distribution of the open tow web may be varied as desired to arrive at particular article thicknesses directed towards particular article uses.
