A method of electrospinning (40) is provided, and an electrospinning device (1; 30). The method comprises (i) holding (41) a liquid comprising a polymer melt or a polymer solution in a container (2), (ii) letting out (42) a stream of the liquid from the container through at least one nozzle (3), (iii) creating (43) a voltage difference between the nozzle (3) and a collecting surface (4), (iv) collecting (44) electro spun material coming from the nozzle (3) so as to form a fibrous structure (8) on the collecting surface (4), and (v) directing (45) a laser beam (13) towards the collecting surface (4) so as to locally remove a part of the fibrous structure (8).

A molding method is performed for molding a composite material in which resin is injected in a state in which a fiber base material is disposed in a cavity formed in a metal mold and the resin is cured to form the composite material. The molding method includes enhancing wettability of a portion of the fiber base material, and disposing the portion of the fiber base material in a narrow portion in which a gap constituting the cavity is smaller than other locations.

Methods are described for treatment of aramid fibers to modify the surface of the fibers. The treated fibers have improved adhesion to elastomer materials as compared to untreated fibers. Modification methods include irradiating the fibers, compressing and straining the fibers under a constant pull force and immersing the fibers in a coupling agent fluid. The treated fibers can be used with elastomers and provide reinforcement elements in products such as tires.

A system allows a user to create new designs for apparel and preview these designs before manufacture. Software and lasers are used in finishing apparel to produce a desired wear pattern or other design. The user's preview may be based upon a two-dimensional image of a wear pattern in a laser input file and, from a set of two-dimensional images of a base garment, create a three-dimensional view of the base garment with the wear pattern.

The described incandescent tension annealing processes involve thermally annealing twisted or coiled carbon nanotube (CNT) yarns at high-temperatures (1000 C. to 3000 C.) while these yarns are under tensile loads. These processes can be used for increasing yarn modulus and strength and for stabilizing both twisted and coiled CNT yarns with respect to unwanted irreversible untwist, thereby avoiding the need to tether torsional and tensile artificial muscles, and increasing the mechanical loads that can be moved by these muscles.

Problem: To provide an airbag fabric and a coated fabric for airbags that are lightweight and compact while maintaining the tensile strength required for airbags, and that can mitigate damage to seams of an airbag when the airbag deploys; and that allow for stable airbag deployment.

Solution: An airbag fabric that is a fabric comprising a synthetic fiber, the fiber that constitutes the fabric having a total fineness of 200 to 400 dtex, an average edgecomb resistance retention in the warp and weft directions after heating at 210 C. for 30 seconds of 60% or more, and a residual shrinkage of 1.5% or less in both the warp and weft directions.

A composite fabric having self-regulating Infrared emissivity includes meta fibers formed with optical nanostructures and an environment (temperature and/or moisture) responsive mechanism configured to adjust a relative disposition between the optical structures to control the electromagnetic coupling therebetween, thus regulating the infrared emissivity of the composite fabric to maintain a user of the fabric in a temperature/moisture comfort zone. The environment responsive mechanism may include a temperature responsive polymer layer on the fiber capable of expansion/shrinkage depending on the applied temperature, or a moisture responsive fiber changing its shape depending on the moisture level to affect spacing between the optical nanostructures.
