Definitions
- the present invention relates to installations for producing spunbond nonwoven webs.
- These nonwoven plies are formed from continuous plastic filaments, and most often with an average diameter greater than 7 microns, in particular between approximately 8 and 30 microns.
- Filaments are formed by extruding molten plastic from a plurality of thin, usually circular, capillary holes in a die, the diameter of the extruded filaments being reduced rapidly after cooling in what is often called an attenuator.
- the filaments thus drawn are separated as best as possible from each other and fall on a conveyor where they form the sheet.
- the air and water permeable conveyor is a very expensive component of the installation. However, it is found that it must be changed well before it is worn out, because some of its parts become clogged and then give a nonwoven web which is no longer sufficiently regular and of good quality.
- the invention overcomes this drawback by an installation for producing a spunbond nonwoven web in which the conveyor has a longer service life, which gives a better quality nonwoven web and which is simpler and less expensive than known installations. so far.
- the subject of the invention is therefore an installation for producing a spunbond nonwoven web, comprising a die arranged so as to deposit filaments in a web at a deposition point on an endless conveyor and means for consolidating the web at a consolidation point downstream from the depot.
- the consolidation means consist of a device for projecting a jet of fluid onto the sheet directly at the consolidation point.
- directly is meant without interposition between the device for projecting a jet of fluid and the point of deposition of a consolidation device of another type, in particular with rollers.
- the button By projecting a jet of fluid, in particular a jet of liquid, and, most simply, a jet of water, on the sheet at the point of consolidation, on the one hand, the button is cooled which has less tendency to adhere, and , on the other hand, it is not compressed to the point of bursting it and bringing out the molten mass from the heart. Admittedly the button is incorporated in the spunbond nonwoven web which passes, but the defect does not reproduce any more with the following passages of the conveyor.
- the conveyor is usually a synthetic or metallic fabric, usually polyester or polyamide, sometimes bronze or stainless steel.
- the air permeability of the conveyor is generally between 250CFM and 800 CFM.
- a suction box was provided at this point. This box necessarily had large dimensions, because the diameter of a roll requires it to be removed from the bottom of the die assembly. As a water jet projection device can be much narrower than a roller, we can bring the deposit point and the consolidation point closer so that we can now do without this long and bulky box and therefore expensive.
- the deposition point which is a line corresponding to the intersection of the plane of symmetry of the die assembly and of the conveyor, and the consolidation point which is also a line extending substantially over the entire width of the conveyor and which is defined by the point of impact of the jet on the conveyor, are at a distance from each other less than 1m.
- the projection device can be a row of fluid orifices or several parallel rows of orifices, preferably two rows, each row being perpendicular to the direction of circulation of the conveyor.
- the consolidation point can be considered as the center line of the center row.
- the consolidation point passes through the middle of the interval between the central rows, for example between the second and third row, if there are four.
- the orifices preferably have a diameter of 70 to 200 microns with an interval between the orifices of 0.4 mm to 5 mm.
- a device for drying the sheet which is preferably above the conveyor, while there is provided below and preferably upstream of the drying device a setting device under vacuum which also facilitates the dehydration of the sheet.
- the invention also relates to a spunbond nonwoven ply also hydrodynamically intermingled.
- FIG. 1 is a schematic sectional view of an installation according to the invention
- FIG. 2 represents a variant.
- the installation according to the invention comprises a water-permeable mesh conveyor 1, made of a material resistant to corrosion and rust, in particular polyester, which passes over idler rollers 2, as well as over a drive roller 3 and tension rollers 4.
- the endless conveyor rotates with an upper horizontal strand which, in Figure 1, goes from left to right.
- the conveyor is a set of conventional dies comprising a dies 5 proper from which protrude spunbond filaments 6 which are cooled by a cooling device 7, then stretched and reduced in diameter in an attenuator 8 before being opened in a device 9 for forming and falling on the conveyor 1 at a point 10 of deposit.
- a suction box 11 Below the horizontal strand of the conveyor 1, there is provided opposite the deposit point 10 a suction box 11.
- a box 14 suction is arranged opposite the device 12 for spraying water on the other side of the horizontal strand of the conveyor 1.
- Downstream of the consolidation point 13 is provided above the horizontal strand of the conveyor 1 a device 15 for infrared drying, while upstream of this device 15 is provided below the horizontal strand of the conveyor 1 a device 16 for placing under empty.
- the consolidated spunbond nonwoven web is detached from the conveyor 1 to pass through a calender 17.
