Problems solved by technology

[0003] With the above-mentioned equipment known from practice, which is the starting point of the present invention, it is possible to produce spunbond nonwoven fabrics, but its properties do not meet all requirements
In particular, the uniformity of the stacking of spunbond nonwovens or the uniform arrangement of the monofilaments during stacking is not satisfactory
Spunbond nonwovens produced with known equipment often exhibit inhomogeneities in their filament density and mesh width
This inhomogeneity causes undesirable irregularities especially in the strength, extensibility and air permeability of the nonwoven

Embodiment Construction

[0021] The drawing shows a plant for the continuous production of spunbonded nonwoven webs from aerodynamically stretched thermoplastic monofilaments. The device has a spinning head 1 and a cooling chamber 2 arranged below the spinning head 1, into which process air can be supplied for cooling the filaments. Adjoining the cooling chamber 2 is an intermediate channel 3 , behind which is a stretching unit 4 with a pull-down channel 5 . A laying unit 6 is connected to the drop-down channel 5 . A stacking device in the form of a continuously moving stacking mesh belt 7 for stacking monofilaments into a spunbond nonwoven fabric web is provided below the laying unit 6 .

[0022] exist figure 1 The cooling chamber 2 according to the invention and the air supply compartment 8 arranged next to the cooling chamber 2 can be seen in the drawing. In the exemplary embodiment shown, the air intake compartment 8 is divided into an upper intake compartment segment 8a and a lower intake comp...

Abstract

A spun-bond web production apparatus comprises a spinneret for producing descending thermoplastic synthetic resin filaments; receiving device for receiving filaments; continuously movable collecting foraminous belt; and at least two mutually independently controllable suction zones beneath the belt for drawing air and including a primary suction zone at which a greater part of the filaments are drawn onto the belt. A spun-bond web production apparatus comprises a spinneret (1) for producing descending thermoplastic synthetic resin filaments; receiving device below the spinneret and receiving filaments for aerodynamically stretching the filaments; continuously movable collecting foraminous belt (7) displaceable longitudinally in a web-producing direction below the receiving device to produce a spun-bond web; and at least two mutually independently controllable suction zones (11) beneath the belt for drawing air through and in succession in the web-producing direction, and including a primary suction zone at which a greater part of the filaments are drawn onto the belt and at least one other suction zone.

Description

technical field [0001] The invention relates to a device for the continuous production of a spunbonded nonwoven web from aerodynamically stretched thermoplastic monofilaments, which has a spinnerette for feeding the monofilaments, wherein a spinnerette is arranged below the spinnerette There is a continuously moving overlapping mesh belt on which monofilaments can be laid to form a spunbonded nonwoven fabric, wherein a suction device is provided on the overlapping mesh belt for suction through the overlapping mesh belt (Ablegesiebband) air suction device. Background technique [0002] The spinneret has many spinning orifices through which thermoplastic monofilaments can be extruded. Within the scope of the invention, the monofilaments first pass through a cooling chamber into which process air for cooling the monofilaments can be fed from an air supply chamber. The monofilament then expediently reaches a stretching unit with a down-draw channel, to which a lay-up unit is c...
