Abstract:
The present invention includes a neck-bonded laminate and a process for forming a neck-bonded elastic laminate, the laminate including a primary elastic region and a secondary elastic region. An exemplary process for forming the laminate includes providing a necked material and overlaying the necked material with an elastic sheet. The necked material and elastic sheet are passed through a nip between two rollers, the rollers being configured to form a primary elastic region and a secondary elastic region and the secondary elastic region having higher strength than the primary elastic region.
Abstract:
Flexible composites which are ballistic and stab resistant. The composites are formed from at least one, and preferably a plurality of, fibrous layer comprising a network of high tenacity fibers. A stack of a plurality of fibrous layers is consolidated in a desired pattern over a substantial portion of its surface area which results in areas which are consolidated and areas that are unconsolidated. The unconsolidated areas provide flexibility to the overall composite structure and the structure is resistant to ballistic projectiles and/or sharp objects. Body armor formed from the composites is comfortable to wear and reduces the degree of trauma to the wearer as a result of impact by the ballistic projectile or sharp object.
Abstract:
A method of manufacturing an oriented film of thermoplastic polymer material comprises extrusion of a film in tubularform from an extrusion die, orienting the film in a main direction of orientation during the haul-off from the die while in molten or semi-molten state, the direction being at an angle between 0 and 45- to the axis of the tube, followed by cutting of the tube at an angle to its main degree of orientation to form a web having an orientation of no less than 20 to its longitudinal direction, which method involves segmental stretching of the film to form an array of linear bosses (1), being of thicker material, integrally connected by thinner webs (2), said bosses and webs extending in a direction which is generally parallel with the direction of orientation, forming an acute angle to the longitudinal direction of the web, the method involving, after segmental stretching and cutting, shearing of the bosses along one another under re-orientation in the connecting webs, to increase the angle at which the bosses and webs extend relative to the direction of orientation. The bosses are separated from one another by no more than 3 mm. The shearing operation may be carried out by segmental rollers (5).
Abstract:
The present invention is directed to a hydroentangled nonwoven fabric with improved flame retardant properties and the making thereof, whereby the nonwoven fabric is differentially entangled to collapse upon itself and self-extinguish upon burning. The self-extinguishing fabric further exhibits favorable tactile and ductile softness while obtaining sufficient physical strength.
Abstract:
Die Erfindung betrifft ein Verfahren zum Herstellen eines Schallisolations-Formteils (1) mit Masse (2) und Feder (3), wobei sowohl Masse (2) als auch Feder (3) auf Grundlage des gleichen Materials, insbesondere Polyurethan, hergestellt werden. Zur Bildung einer Masse werden Reaktionsstoffe und Füllstoffe in eine Form eingebracht, insbesondere eingesprüht bzw. eingespritzt und zur Reaktion gebracht. Das Einsprühen bzw. Einspritzen wird dabei so gesteuert, dass die Reaktionsstoffe und die Füllstoffe in die Form örtlich in unterschiedlicher Menge und/oder Zusammensetzung zugeführt werden abhängig von der örtlich zusammen mit der Feder (3) zu erreichenden Schalldämmung, die anschließend durch Ausbilden von Schaum auf der so gebildeten Masse (2) in der selben Form ausgebildet wird. Hierdurch können bei geometriegleichen schallzuisolierenden Flächen dreidimensionale geometriegleiche Formteile (1) mit sowohl unterschiedlichen akustischem als auch mechanischem Verhalten in vorgegebener Reihenfolge hergestellt werden.
Abstract:
The wall section of a container is formed in multiple layers in terms of a crystal density to make high the crystal density of a surface layer, thereby increasing the strength of a stretch blow container and facilitating a heat-resisting treatment. A thin-walled plastic container (2) which is molded by stretch-blowing a bottomed preform in vertical and lateral directions. The wall section is constituted of high-crystal-density inner/outer-side surface layers (2a) by stretching, a core layer (2b) lower in density than the surface layers (2a), and an intermediate layer (2c) inclined in crystal density with respect to the both layers (2a, 2b).
