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

[0022] The drawing shows an apparatus 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 movable stacking mesh belt 7 for stacking monofilaments into a spunbond nonwoven web is provided below the laying unit 6 .

[0023] In FIG. 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 exemplary embodiment shown, the air intake compartment 8 is divided into an upper intake compartment segment 8a and a lower intake compartment 8b. Process a...

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 present invention relates to an apparatus for the continuous production of spunbonded nonwoven webs from aerodynamically stretched thermoplastic monofilaments. 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 connected, which preferably consists of at least one diffuser. A stacking device for stacking monofilaments into a spunbonded nonwoven web is arranged below the laying unit, wherein the above-mentioned continuously movable stacking mesh belt is an integral part of the stacking device. Monofilaments are laminated on this laminated belt to form a spunbonded nonwoven fabric. ...
