摘要:
The invention relates to modified reinforcement fibers for use in a variety of applications. The modification includes crimping linear or straight reinforcement fibers to create a deformed or different shaped reinforcement fiber. Examples of the shaped fibers resulting from crimping include w-shaped, s-shaped, z-shaped and wedge-shaped.
摘要:
The present disclosure relates to a method of forming yarns and preparing surgical devices therefrom. The yarns include at least one first filament possessing a polymer core and first reactive members known to have click reactivity on a surface thereof and at least one second filament possessing a polymer core and second reactive members known to have click reactivity on a surface thereof. The first and second reactive members are complementary such that they interact to covalently bond the filaments together.
摘要:
A plurality of substantially parallel continuous filaments, e.g. of cellulose acetate or rayon, and preferably newly formed, are consolidated or partially stabilised, e.g. by application of solvent and pressure, by hydroentanglement, by embossing, or by crimping and stretching. The filament assembly or subassemblies thus produced are further stabilised by folding, bundling, twisting or intertwining, e.g. to form braids (10), and are then bonded to a carrier layer or sandwiched between outer layers (12, 14), e.g. by hydroentanglement, melt blowing, spinbonding etc. The stabilised filament assemblies may be arranged spaced transversely and may be cut just prior to bonding so as also to provide longitudinally spaced three dimensionally thicker regions, ready for conversion to finished products such as absorbant feminine hygiene products or medical swabs or the like.

摘要:
Vorgeschlagen wird eine Vorrichtung (1) zum Erzeugen von Effektgarnen beim Texturieren von Garn durch Erzeugen von Flammen durch kurzzeitige Garnüberlieferung, mit einem motorisch angetrieben linear vom Fadenlauf (35) weg bewegbaren Mitnehmer (4), wobei der Mitnehmer (4) einen Fadenführer (9) aufweist, um durch Greifen eines Fadens (2) des Garns mit dem Fadenführer (9) und seitliches Auslenken des Garns aus dessen Fadenlauf (35) eine Garnunterlieferung zu erzeugen. Dabei sind Auslösemittel (10) vorgesehen, eingerichtet, den Faden (2) an einem seitlich vom Fadenlauf (35) des Fadens (2) liegenden Auslenkpunkt aus dem Fadenführer (9) freizugeben, um die Garnüberlieferung durch abruptes Beenden der Auslenkung des Garns zu erzeugen. Die Auslösemittel (10) bilden eine Rampe aus, wobei die Rampe derart positioniert ist, dass der Faden (2) im Bereich des Auslenkpunktes mittels des Fadenführers (9) auf die Rampe aufschiebbar ist, wobei der Faden (2) durch das Aufschieben zu dessen Freigabe aus dem Fadenführer (9) heraushebbar und/oder über den Fadenführer (9) weghebbar ist. Die Vorrichtung funktioniert losgelöst von der Fadenspannung.
摘要:
A ribbon curling device having opposing first and second surfaces bound by two side edges and front and rear ends. The device has an elongated handle and a ribbon curling region extending from the handle and comprising a curling edge, the region having first and second ends. The first end of the ribbon curling region lies proximate to the front end of the handle and wherein the second end of the ribbon curling region is tapered.
摘要:
A novel textile fabric comprised of pile-like yarns in which individual component yarns, at least one of which is texturized, comprising individual pile-like yarns have different shrinkage characteristics, and a method for making and patterning such fabrics. Upon the application of a shrinkage agent (e.g., heated air streams), either uniformly or selectively to the pile surface, the individual component yarns shrink to different degrees. By shrinking the relatively high shrinkage component yarns more than the adjacent relatively low shrinkage component yarns, the visual exposure of the relatively low shrinkage yarns is increased, and the visual contribution of the aesthetic qualities (e.g., color, light reflectivity, etc.) of such low shrinkage yarns is enhanced.
摘要:
An apparatus for crimping and permanently heat setting an inorganic or polymeric precursor fiber (18) comprising a mechanical crimping means (13), a conveying means (11) which receives the crimped fiber (18), and a heating or irradiation zone (16A, 16B) through which the conveying means (11) and fiber (18) pass without applying stress or tension to the fiber.
