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.

Methods and systems are described for continuously densifying at least one nanofiber sheet using heat and an applied force that can include both compressive and tensile components. Nanofiber sheets densified using these techniques have a more uniform and more highly aligned microstructure than nanofiber sheets densified using a solvent alone. As a result, the nanofiber sheets of the present disclosure have, for example, higher tensile strength and better electrical conductivity than nanofiber sheets densified using other techniques.

There is provided a plain-weave fabric excellent in low air permeability and waterproofness. Further, there is provided a stent graft excellent in low water permeability mechanical properties and catheter storage capacity, including the plain-weave fabric as a graft substrate. A plain-weave fabric woven by interlacing weaving yarns in warp and weft, in which weaving yarns YA and YB arranged in the same direction have different crimp ratios A and B, respectively, a relationship thereof satisfies Formula 1, and the crimp ratio B is 4% or more, and the plain-weave fabric is preferably used for a stent graft; A?B?1.2.

The present disclosure relates to a method for producing a nonwoven fabric which improves the impregnation property of a fabric softener in the nonwoven fabric so as to apply the nonwoven fabric to a dryer sheet (sheet-type fabric softener). In a nonwoven fabric made of two types of polyester long fiber mixed filament yarns, by widening the specific surface area, adjusting the evenness deviation to be small and increasing the porosity, the impregnation property of a fabric softener is improved even when the nonwoven fabric is made lightweight, and the nonwoven fabric can be applied to a dryer sheet.

Provided is a flow path material for a liquid separation apparatus, which is less likely to collapse upon the application of a high pressure to the flow path material and causes a lower reduction of the flow rate. The flow path material for a liquid separation apparatus includes a tricot fabric containing thermoplastic core-sheath composite fibers each made of two kinds of polyester resins having different melting points or softening points. The flow path material for a liquid separation apparatus is configured such that: in the thermoplastic core-sheath composite fibers, a high-melting-point component is placed in the core, while a low-melting-point component is placed in the sheath; the tricot fabric is a tricot knitted fabric knitted with a two-guide-reed knitting machine using the thermoplastic core-sheath composite fibers as a front yarn and a back yarn and is rigidified by the thermoplastic core-sheath composite fibers being bonded to each other; the tricot fabric has a wale density of 45 to 70 yarns/inch (2.54 cm) and a course density of 40 to 70 yarns/inch (2.54 cm); and, when the tricot fabric is heat-pressed at 90? C. and 4.0 MPa for 3 minutes, the percentage of change in the thickness of the tricot fabric before and after pressing is 10% or less.

It is intended to improve texture of a decoration using a stitch line while improving workability in sewing for forming the stitch line at a skin material, to promote manufacturing efficiency as compared to formation of a stepped shape only by sewing, and to reduce the number of steps. A skin material is used for a conveyance seat, and is molded using a die. The skin material includes a linearly-extending stepped portion having a stepped shape transferred from the die, and a stitch line sewn along the stepped portion. The stepped portion serves as a guide upon formation of the stitch line.
