Definitions
- the invention has for its object to find a method and the associated device with which this slight surface wear ability is improved and still a good bond of the pulp fibers in the carrier fleece can be achieved. It is also important to ensure that the applied pulp layer is not lost or is lost little when it is effectively connected to the carrier fleece.
- the invention sees the solution to the problem in that the spunbond fleece is pre-consolidated with the superabsorbent material before coating, such as needling with air or calendered for pre-consolidation, then the wood pulp layer is applied and both together one Hydrodynamic water needling is then solidified and then dried.
- the consolidation of the calendering of the continuous fiber fleece before further processing not only improves the abrasion resistance of the end product, but also reduces pulp loss when needling water into and through the fleece If the consolidation is too high, the bonding points are too diverse, then a connection of the pulp layer to the calendered nonwoven is difficult due to the needling of water firm integration of all surface fibers is achievable In the case of a nonwoven product with only one spunbond layer, only the roller that is adjacent to the spunbond layer needs to be heated
- the pulp layer is hydrodynamically bonded to the nonwoven in this manufacturing process, otherwise the product cannot survive in practice due to the formation of a layer. It is even better if another pre-consolidated continuous fiber or carded nonwoven is applied to the pulp layer and only that three layers are needled together hydrodynamically. End calendering is also advantageous then. It is also advantageous to use a calendered carded fleece as carrier fleece instead of an endless fiber fleece, to which a spunbond fleece is then placed as a cover layer
- FIG. 1 is a side view of a contour system for producing a composite fleece only with a support base
- Fig. 2 also in side view of the system according to Fig. 1 supplemented by the supply of an additional cover layer made of a continuous fiber fleece in front of the water needling and
- FIG. 3 shows a system according to FIG. 2, however, with a carding system at the inlet for producing a carding fleece as a support layer
- Lot band 3 is assigned to a calender 5, which, if desired, supplies energy and warmth, possibly also a finely embossed solidified fleece.
- the calendering device can also be replaced by an air-hardening device, not shown here an intimate connection with the continuous fiber fleece is established.
- the pulp fiber is fed, for example, with a device 6 according to EP-A-0 032 772. Both fleece layers together are then acted upon with the hydrodynamic needling 7 for connection, which instead of on one Continuous belt according to FIG. 1 can also be carried out on a permeable drum according to FIG. 2.
- the contour system according to FIG. 2 corresponds to that according to FIG. 1, there is only a second, only slightly pre-consolidated continuous fiber fleece 12 produced with the device 10, which of course can also be presented with a roll (not shown), that is to say prefabricated. This also applies to wearing 1 read with the device 1 - 4.
- the upper covering 12 should also be pre-consolidated with a calender 11 after the covering 12 has been deposited on the pulp layer laid with the device 6 on the base 1 of the device 1, 5 , the above-mentioned water needling takes place, which in this exemplary embodiment can also be carried out in several stages from both sides, if necessary, since the pulp layer is covered on both sides by a fleece Arrows indicated nozzle bars are assigned from above.
- the subsequent drying takes place here r with a different type of through-air dryer 9, the screen drum 9 'of which the fan is assigned externally.
- the calender 15, 16 can also be run through here, but in which case both rollers 15, 16 are then to be heated
- a card 1 '- 4' serves as the fleece laying direction.
- the carding machine consists of a box feeder V mt yi ⁇ er arranged below shaking chute 2 ', which passes the cardboard fibers with the scratching and tearing rollers 3' evenly spread over the width.
- the following endless belt 4 ' transfers the laid carded nonwoven to the calender device 5 as described above.
- a sheet bond fleece can be used as the cover layer 12, which can be formed in the unit 10 shown schematically.
- a spunbond fleece as the carrier fleece, to which a carded fleece is placed after the pulp layer.
- the unit 10 would then represent a device as it is designated by the reference numerals V-4 ', while a spunbonding device similar to the reference numerals 1, 2 is arranged in the place of the card.
