Abstract
The invention relates to a method for the production of geotextiles from mel t- spun fibers. The melt-spun endless fibers are continuously transported in an unimpeded manner on a screen belt along all hardening and post treatment zon es.
Description
~4v0 200~f/048667 PCT/EP2003/013310 Method for the Production of Geotextiles From Melt-Spun Fibers The invention relates to a method for the production of geotextiles from melt-spun fibers, in which the melt-spun endless fibers ar a 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 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 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 foiming between the endless conveyors.
Both methods should avoid disruptions in the not yet sufficiently hardened fiber web.
v~10 20044048667 CA 02507605 2005-05-26 pCT/EP2003/013310 However, the first disruptions in the fiber web already occur after the depositing of the fibers during the transport to the first hardening zone.
It was the task of the present invention to provide 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.
The subject matter of the present invention is therefore 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 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 on the endless screen belt and transported on that screen belt to the first stitch-bonding stage. At the same time, the deposited filaments are fixated on the screen belt by suction zones during the transport, ~,VO 2004,/048h67 PCT/EP2003/013310 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 j ets act through the screen belt and/or the screen belt serves as a support, depending on the stitch-bonding device assembly.
For the construction variant of stitch-bonding through the screen belt, the screen belt has a mesh width of 1 - 8 cm ~, preferably 2 - 5 cm-1.
If the screen belt acts as a support, the screen belt has a mesh width of 10 -100 cm-1, preferably 20 - 60 cm-1.
After stitch-bonding in the first stitch-bonding stage, the geotextile is sufficiently 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 the screen belt.
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 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;

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 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 foiming between the endless conveyors.
Both methods should avoid disruptions in the not yet sufficiently hardened fiber web.
v~10 20044048667 CA 02507605 2005-05-26 pCT/EP2003/013310 However, the first disruptions in the fiber web already occur after the depositing of the fibers during the transport to the first hardening zone.
It was the task of the present invention to provide 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.
The subject matter of the present invention is therefore 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 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 on the endless screen belt and transported on that screen belt to the first stitch-bonding stage. At the same time, the deposited filaments are fixated on the screen belt by suction zones during the transport, ~,VO 2004,/048h67 PCT/EP2003/013310 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 j ets act through the screen belt and/or the screen belt serves as a support, depending on the stitch-bonding device assembly.
For the construction variant of stitch-bonding through the screen belt, the screen belt has a mesh width of 1 - 8 cm ~, preferably 2 - 5 cm-1.

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 the screen belt.
:'VO, 300,./048667 PCT/EP2003/013310 By this 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.
The geotextiles 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 polyolefines, such as polypropylene, polyamides or polyester.
Another subject matter of the present invention is a device for the production of geotextiles from melt-spun fibers, characterized in that a screen belt is guided beneath the deposit device, to which suction zones are attached, and that the screen belt is guided to the first hardening zone.
In Fig. 1 and Fig. 2, such devices are presented:
