Abstract

A non-woven (4) consisting of outer layers of fibers that can be melt bonded, e.g. bi-component or homopolymer fibers, and a central layer of cellulose or super-absorbent pulp fibers is air laid in successive layers from laying heads (1, 2, 3). The non-woven is then optionally consolidated by heat (5), needle punched by a water jet treatment (6, 7) on both sides and finally dried (8). Alternatively the initial heat consolidation (5) is omitted and heat bonding is combined with the drying stage followed by sizing in a calender.

Description

WO 97/30223 describes an air-lay process for producing a composite nonwoven is known in which several air-laying molding heads of the type according to EP 0 032 772 behind are arranged together and a composite fleece made of binding fibers, then cellulose fiber and make binding fibers again. This type of production has compared to the Carding fleece formation the advantage of the higher achievable speed. To the festival Then a calender and a ventilation unit are used, which with Heat to bind the binding fibers together.

A consolidation of this kind does not create a fleece that meets the conditions in the Practice fulfilled. The individual layers have no cohesion, the fleece Delaminate parts, they split. In addition, the fleece surfaces are ver susceptible to wear.

The invention has for its object to find a method from which fibers assembled such a fleece for the air-lay process and then like this should be solidified, among other things to prevent delamination.

Starting from a process in which to solidify one after air laying process produced fleece - consisting of two outer layers of ge cut thermally activated fibers and one arranged between them Layer of cellulose fibers such as superabsorbent pulp by continuous formation first the lower layer, then the pulp layer and finally the upper layer - only a thermal treatment is provided is vorese according to the invention hen, the thermally activated staple fibers solely from hot melt adhesive fibers such as ins special bicomponent fibers or and other fibers, such as homopolymer fibers, to choose and the three-layer fleece for strengthening, so also for intimate connection to subject the layers to hydrodynamic needling.

This type of fleece composition of the cover layers guarantees a pilling and linting-free surface that is still permeable to liquid and also a stronger one can cover absorbent pulp layer. The two outer layers of the fleece this  The species are intensified by the needling of water and also with the Pulp layer connected, which is the dreaded lamination of the fiber types after the Solidification hindered. Adequate consolidation of the surface layers are required preferably treat both layers with water needling, i.e. the com Needle fleece on both sides.

The hot melt adhesive fibers should be connected to and with each other for further connection Heat treated. The heat continues to affect the required surface finish Creativity of the fleece. The bicomponent fiber is particularly advantageous, because it remains in the heat treatment as the actual fiber, while the ex hot melt adhesive fibers can melt and shrink, leading to the formation of resistant surface is a disadvantage. The heat treatment can be on under a wide variety of types, essential is a good binding of the fibers to the surface across the cover fleece.

A device of the type according to the invention is exemplified in the drawing poses. Based on this example, further inventive details are to be explained. Show it:

Fig. 1 is a side view of a continuous system for the production and consolidation of a fleece laid dry by the air-lay method and

Fig. 2 shows a system similar to that of FIG. 1 without thermal bonding after the laying process.

First, the fleece is to be formed from staple fibers and pulp. The staple fibers must be cut so short that according to the air-lay method with devices according to z. B. EP-A-0 032 772 can be placed, that is, they have a length of 4-8 - maximum 10 mm in length. The molding head 1 is then to be loaded with the staple fibers for the basic nonwoven layer. The staple fibers are those that have to be glued under the influence of heat. In particular, bicomponent fibers are advantageous here, which have the advantage that they do not shrink when exposed to heat, but are retained as fibers. Then on the base fleece formed with the molding head 1 , the pulp layer with the molding head 2 , possibly with a further molding head not shown, a thicker pulp layer, and then the top cover layer of the staple fibers are stacked on top of one another. This composite fleece 4 is now to be consolidated, which has previously only been done by means of thermal bonding.

After the installation according to Fig. 1, the web 4 is first pre-consolidated by means of heat in the device 5. This can be done with hot air (ventilation), but also with exposure to infrared rays or with calendering. This measure of solidifying before has the advantage of better surface closure of the cover layers, which can prevent a greater loss of pulp during subsequent needling. In the system of FIG. 2 is omitted in this pre-consolidation under heat. Depending on the fiber and other conditions, pre-consolidation can also be dispensed with.

The composite fleece 4 is then struck with the hydrodynamic needling. Since this is a fleece with a cover layer on both sides, it is expedient to carry out the consolidation with the water jets from both sides. Therefore, the needling device with two drums 6 and 7 is shown in the figures, which is only intended to indicate that the fleece meandering around the drums to be loaded on both sides with water jets. This hydroentanglement not only affects the surface of the composite fleece, but also the deeper cohesion of the layers, so that delamination of the individual fleece layers later no longer occurs.

After the composite fleece has solidified and the layers have been joined together by means of the water jets, the fleece must be dried. For this purpose, a ventilation dryer 8 , such as a sieve drum dryer, is advantageous. Finally, the fleece can still be calibrated by means of the device 9 , as is only shown in the system according to FIG. 2.

This type of composite nonwoven is very inexpensive because at higher speeds, such as. B. 400-500 m / min can be produced. A very absorbent product of 40-100 g / m 2 can be produced because a thick pulp layer can be applied. The cover layers should be thin in relation to the pulp layer, e.g. B. with 10 g / m 2 , while the pulp layer can be 60 g / m 2 heavy. Through a combination of thermal bonding and water needling, not only is the surface essentially free of linting and pilling, but the nonwoven is solidified through and through, which makes it difficult to divide the nonwoven layers.
