Nonwovens are growing in significance within the design sector. They are finding increasing application as wall coverings, upholstery and furnishing fabrics. The potential to laser cut and mark nonwovens for design purposes adds to their appeal within the sector. An example of this is Mercedes-Benz use of laser engraved Alcantara®, which is a synthetic leather constructed using nonwoven technologies. This paper reports on techniques used to engineer non...$28.00

The paper is an examination of a novel process of combining a traditional textile technique with laser cutting to produce hybrid constructions of interest to the garment and interiors industries. Pleating is a technique performed either mechanically or by hand to manipulate flat sheets into three-dimensional structures. In combination with laser cutting, pleats or folds ma...$28.00

World market competition currently boosts trends like mass customization and open innovation which result in a demand for highly individualized products at costs matching or beating those of mass production. This work focus on the resolution of the production related dilemma between scale and scope, e.g. either the low-cost production of high quantities or the high-end and thus cost-inten...$28.00

In-situ laser cladding enables the formation of a uniform clad by melting the powder and substrate to form a composition from pure powder components. Since TiC has desirable properties such as hardness, wear and corrosion resistance, titanium (Ti) and graphite (C) are used as a composite material (i.e., TiC) to increase hardness and wear resistance of AISI 1...$28.00

During laser welding, laser-induced plume ejecting from a keyhole affects welding results greatly, and therefore this plume is generally removed with a shielding gas. In remote/scanning welding, however, a tall plume is generated in the case of a long focal length lens and no shielding gas, and the weld penetration is greatly reduced. This result is attributed to the Rayleigh scattering due to ultrafine partic...$28.00

Precise positioning of the laser beam on the work piece is crucial for high quality laser welds; e.g. for butt welding the focal point of the laser beam with respect to the joint must be maintained within an accuracy better than 20 - 150 µm, depending on the focused beam radius. These stringent a...$28.00
