The present invention relates to a device and to a method for producing a texturized filament or yarn, wherein at least one filament is guided into a draw device, is guided there by a pair of intake rollers towards at least two pairs of drafting system rollers and drawn by the same, downstream of which is disposed a texturizing device with a cooling drum. Downstream the texturizing device with the cooling drum is disposed at least one cooled drafting system roller, by which the filament, respectively the yarn is cooled to a temperature of 0° C. to 50° C.

A method of manufacturing artificial turf creating a liquid polymer mixture, wherein the polymer mixture is at least a two-phase system. A first one of the phases includes a first polymer and a first dye, and a second one of the phases of the polymer mixture includes a second polymer and a second dye. The second dye has a different color than the first dye, the second polymer being of the same or of a different type as the first polymer. The first and the second phase are immiscible, the first phase forming polymer beads within the second phase. The method further includes extruding the polymer mixture into a monofilament including a marbled pattern of the first and second color; quenching the monofilament; reheating the monofilament; stretching the reheated monofilament to deform the polymer beads into threadlike regions and to form the monofilament into an artificial turf fiber; and incorporating the artificial turf fiber into an artificial turf backing.

A draw device into which at least two filaments are guided for producing a multi-coloured yarn from differently coloured filaments which consist of a plurality of endless filaments includes a pair of intake rollers for receiving the at least two filaments. Two pairs of drafting system rollers follow the intake rollers to draw the at least two filaments. A texturizing device comprising a texturizing nozzle with a cooling drum is disposed downstream of the two pairs of drafting system rollers to texturize the at least two filaments, wherein at least one yarn is formed from the filaments in the texturizing nozzle. At least one further nozzle is disposed exclusively upstream of the texturizing device in which each filament is separately interlaced. The filaments are drawn on at least one of the two pairs of drafting system rollers at a speed of at least 1,700 m/min.

Shown are thermo-fusible conjugate fibers having a high degree of crystallinity, while a degree of orientation is suppressed, and a bulky and soft nonwoven fabric using the same. The thermo-fusible conjugate fibers have, as a first component, a polyester-based resin, and as a second component, an olefin-based resin having a melting point lower than a melting point of the first component, in which the degree of orientation in the polyester-based resin is 6.0 or less, and the degree of crystallinity therein is 20% or more. The conjugate fibers are preferably sheath-core conjugate fibers in which the first component is a core component and the second component is a sheath component.

A polyamide 46 multifilament has a strength of 6.0 to 9.0 cN/dtex and an elongation at break of 15% to 30%, an elongation rate (E′10) of less than 2.5% after heat treatment at 120° C. for 24 hours and subsequent stretching performed 10 times in a room temperature environment, and the difference (E′10-E′1) between the elongation rate (E′1) of the heat-treated fiber measured after stretching it once in a room temperature environment and its elongation rate (E′10) measured after stretching it ten times in a room temperature environment is less than 0.60%.

An embolic filter balloon is disclosed. The embolic filter balloon may comprise an inflatable balloon portion. Further, the inflatable balloon portion may be coupled to a filter member. The embolic filter balloon may be disposed in a body lumen. In some embodiments, the embolic filter balloon may be configured such that when the inflatable balloon portion is at least partially inflated the filter member extends at least partially across the body lumen. Such a configuration may allow the embolic filter balloon, when deployed, to filter particles greater than a predetermined size from a fluid in the body lumen.
