Description

1 METHOD FOR THE PRODUCTION OF GEOTEXTILES FROM MELT-SPUN FIBERS Background of the invention The present invention in a preferred embodiment relates to a method for the 5 production of geotextiles from melt-spun fibers, in which the melt-spun endless fibers are continuously transported in an unimpeded manner on a screen belt along all hardening and post treatment zones. In DE 196 27 256, a method for the hydromechanical consuming of fibers of a fiber web is described, wherein a multiple needling occurs during alternating web 10 guidance and the transfer from one to another transport device occurs by continuous and stretch-free supporting of the fiber web. For this purpose, the fiber web is supported by a running endless web [sic; conveyor belt?] during the transport from one contact surface to the next. From EP 0 859 076, a device for the hydrodynamic consumption of fibers of a is fiber web is known, wherein, in order to achieve a stronger stitch-bonding, the transporting endless conveyor is assigned an endless conveyor guided in the opposite direction in the first needling unit, and the fiber web is increasingly solidified in the cone gap forming between the endless conveyors. Both method should avoid disruptions in the not yet sufficiently hardened fiber 20 web. However, the first disruptions in the fiber web already occur after the depositing of the fibers during the transport to the first hardening zone. Object of the Invention It is the object of the present invention to substantially overcome or at least 25 ameliorate one or more of the disadvantages of the prior art, or to provide a useful alternative. Summary of the Invention In a first aspect the present invention relates to a device to produce a textile material from melt-spun filaments, the device including: 30 a filament veil; 2 a screen belt having a screen surface, the screen surface being moved along a path extending from the veil, and the screen surface being positioned to receive the filament from the veil and then transport deposited filament in a predetermined direction along said path, s a suction device located along the path and cooperating with the surface to hold deposited filament in place on said surface during the transportation; a compacting belt located down stream of the veil to engage the deposited filament to compact the filament; at least one stitch bonding unit located down stream of said compacting belt; and 10 wherein the screen surface terminates before said bonding unit to provide for delivery of unsupported compacted filament to said bonding unit. Preferably, the suction device extends along a substantial portion of the path. The compacting belt is preferably, positioned to engage with the deposited filaments for at least a part of substantial portion of the path. Preferably, the compacting belt engages 15 with the deposited filament along a predetermined length of the path and the suction device extending along such predetermined length. Preferably, the screen belt is a mesh. The suction device preferably cooperates with the screen surface to allow water jets to act through the screen surface so that non woven stitch bonding occurs. The mesh has a preferable width of 1-8 cm- 1 (0.125 cm to 1 20 cm). The mesh has a preferable width of 2-5cm- 1 (0.2 to 0.5 cm). Preferably, the mesh has a width of 10-100 cm- 1 (0.01 cm to 0.1 cm). The mesh has a preferable width of 20 60 cm- 1 (0.02 cm to 0.05 cm). Preferably the at least one stitch bonding device further hydrodynamically intertwines the unsupported compacted filaments by water jets. In a second aspect the present invention relates to a method to produce textiles 25 from melt-spun filament, the method includes the steps of: depositing filament on a screen surface of a screen belt; moving deposited filament along a path extending down stream from the veil; holding said filament in place on the surface as the surface moves along the path; compacting the moving filament on the surface; and 30 delivering unsupported compacted filament to least one stitch bonding unit. The present invention at least in a preferred embodiment provides a method for the depositing and subsequent hydrodynamic consumption of the fibers, in which a disruption of the fiber web immediately after the depositing of the fibers before the first hardening zone is also avoided.
3 The present invention in a preferred embodiment relates to a method for producing geotextiles from melt-spun filaments by means of hydrodynamic consumption, characterized in that the melt-spun filaments are deposited on an endless screen belt and transported on that screen belt through the first hardening zone, wherein the filaments are 5 additionally fixated on the screen belt by suction zones during the entire process and are therefore already sufficiently hardened in the first hardening zone, so that a disruption free transport without a transport belt is possible. The melt-spun fibers are therefore first deposited in the usual manner one the endless screen belt and transported on that screen belt to the first stitch-bonding stage. At 10 the same time, the deposited filaments are fixated on the screen belt by suction zones during the transport, so that no disruptions can occur during the transport of the unhardened filaments. The speed of the sucked air during this is 1-15 m/s. In the first stitch-bonding stage, the water jets act through the screen belt and/or the screen belt serves as a support, depending on the stitch-bonding device assembly. is For the construction variant of stitch-bonding the screen belt, the screen belt has a mesh width of 1-8 cm 1 (0.125 to 1 cm), preferably 2-5 cm' (0.2 to 0.5 cm). If the screen belt acts as support, the screen belt has a mesh width of 10-100 cm' (0.01 to 0.1 cm), preferably 20-60 cm 1 (0.16 to 0.05 cm). After stitch-bonding in the first stitch-bonding stage, the geotixtile is sufficiently 20 hardened, so that it can also be guided without the support of a transport conveyor without causing disruptions of the structure. If necessary however, the screen belt can also be guided through any further stitch-bonding stages. Thus, non-woven textile formation as well as the stitch-bonding takes place on 25 the screen belt. By this preferred method, it is possible to avoid any disruption in the structure of the yet unhardened geotextile after depositing. Thus, complex process guidance like, for example, an alternating guidance, can be avoided. 30 The geotextile produced in this way are distinguished by a high homogeneity and regularity. As filaments, all raw materials that can be melt-spun can be considered, for example polyofines, such a polypropylene, polyamides or polyester. Another aspect of the present invention is a device for the production of 35 geotextiles from melt-spun fibers, characterized in that a screen belt is guided beneath the 4 deposit device, to which suction zones are attached, and the screen belt is guided to the first hardening zone. Brief Description of the Drawings Preferred embodiments of the present invention will now be described, by way 5 of examples only, with reference to the accompanying drawings wherein: Figure 1 is a schematic side elevation of the device according to the present invention. Figure 2 is another schematic side elevation of the device according the present invention. 10 Detailed Description of the Preferred Embodiments The accompanying drawings schematically depict a device to produce geotextile material from melt-spun filament.
