The invention relates to a non-woven l'exfcilöt-ojcx'ä which, as GruiadXage, has a laminate which consists of split fiber webs arranged in the weft direction and warp direction. S & i of the production of the aea Laminabs is placed on an opal tfasex'bahii arranged in KeGteni-'ickbimg and laterally pulled apart with a network structure, which has been obtained from a uniajdLal stretched film, in the weft direction a laterally bent web of the same cleft tubes as above placed, the weft track being cut according to the width dc-i * chain track. Thereupon the a.no:-Jdmini <: aua the ßkltuss ~ and chain tracks are bound with a binding agent, whereby the tracks practically do not hang in the longitudinal direction. several layers ^ luaii on this Wo I η ο her ge at «» Il tea, Luininatfcä from split fibers,

A flat layer of relaxed lasers is placed on at least one side of the laminate, if necessary the above operations are repeated _? to make a multi-layer product. The fibers are then on the dieae be! STeise constructed product by mechanical JHaßnahmen, such as by a Benadeiu / _{tg} s} entangled with each other after which the fibers, if necessary, at their Krauzungspunkten with a binder coupled W.

of the well-known nielrb woven fabrics, there are those which are made here by processing fibers into a layer of randomly laid entangled curly fibers which is then bound with a binder. However persist these fibers consist entirely of discontinuous short. Fibers that are randomly intertwined, and therefore is the strength both in the warp direction and in the weft direction is low. In addition, the handle is rough and hard. Most of the time, such non-woven fabrics are used as backings etc. used. They own the JiTachtsil that they only Can be used on items of clothing that are discarded after use.

There are also non-gsviebfce Textileuoffe aiit fiber anchoring, Polygamy is established by the fact that one. a layer off arbitrarily abelsgfcä / i entwined short Fasarn on a Coarse-textured base made by weaving is, hangs up, the Faaarn arbitrarily with each other and Biit der Basis devoured by Benalalung and those on diosa white binds intertwined fibers with a binder.

In summary, it can be said that the mentioned invention is applicable to the present Srfin & img with regard to the production of a base from split fibers in the weft direction and warp direction and with regard to the physical properties IW.Ü. differ in the quality of the product. The ψ first © ¥ ei * fahr-en has the disadvantage that only an inferior product with a narrower range of application can be obtained «

In the process according to the invention, for the production of a laminate from split fibers lying in the weft direction and in the warp direction, a laterally torn apart web with the desired width is cut to a length that corresponds to the width of the chain web, and from the side onto the chain web running in the longitudinal direction guided _} which also consists of laterally separated, so-called split fibers, whereby the feeding takes place intermittently, on which form a laminate of chain and split fiber webs , whereupon this fiber arrangement is fixed by a binding agent.

The laminate then runs over a second suction box, where wide threads are placed in advance on the layer as in the first zone by pulling the threads off a roll 17 through feed rolls 18 and an air ejector 19, the second being flat arranged layer of relaxed fibers is created. The heaped raw material for the non-woven textile fabric is removed from the endless belt net 9 each time it passes through the nipping rollers 7 and 7 *, whereupon the belt runs back again and 20 'where the fibers are intertwined. Then the superimposed raw material is passed between nip rollers 21 and 21 * and then through a hot air chamber 22, where the binding agent applied to the bases is heated. As it passes through the squeegee rollers 23 and 23 *, which are located at the level of the exit from the hot air chamber, bonding points are created between the fibers of the bases and the fibers of the layers arranged flat. The product 24 obtained is then fed to a subsequent finishing stage.

The binders can be in the form of powders, emulsions, solutions, or non-stretched films, which

all have a softening point lower than that of the split fiber lies. Such binders are generally got. Dua binder should © have an affinity both against the split fibers that are present in the base, as well as babes opposite & on pierced fibers. "

If a flat layer of fibers, which consists of randomly laid and intertwined short fibers, is to be used, then a method 2112? Production of the flat layer of relaxed fibers can be used, in which a cotton-wool-like fiber layer is placed on the foundation directly through the feed rollers 12 and 18 without the use of a fan or in the case of dsm-free short fibers from an opening in the form of a cotton wool In the case of flat layers of thread drawn apart, the feed rollers 12 and 18 are also used, which are each connected to one another by toothed wheels without an air ejector being used. Here, the hollows 12 and 18 take care of the feeding of the thread layer onto the base with a lead, and thereby a flat layer of relaxed fibers can be obtained on the base in such a way that the bottom layer is in a zigzag shape comes to rest. In this case, there is a high possibility that the threads are arranged in parallel in the longitudinal direction, and as a result, the obtained non-woven fabric is particularly strong in the warp direction after it has been needled. For preparing a product with a well-balanced strength in the warp direction and in the weft direction this case, the fiber density of the trajectories of the laminate consisting of the weft and in the warp direction has ta arranged split fiber webs and is used as a basis 2 to 5 times

or several miles thicker than the fiber thickness of the Chain lift.

In short, the particular features are the erfindimgsgemäßeJi product therein "that l ^r cd; rush not only hinsichtlicb the fact remains that by using a base with a considerably further free surface and with a smaller substrate weight, a sufficient entanglement of the other fibers having the basis of can Verden achieved, but also in the fact that, even if the density of the split fibers w5rd increased in a product to make _t to this solid, the product can shipyards softened characterized in that only thin bases successive sets or in that thin bases in laminated several layers with interposed laid-flat layers of relaxed fibers without increasing the thickness of a layer of the base, as well as in the fact that the increased points of adhesion of the stung fibers can be obtained in one stage or in several stages, namely by a binder that was previously put on the basis is applied, or by a liquid adhesive, which can be solidified by suitable measures, which is also applied shortly before needling ₉ to fix the fibers au, with the result that a product can be obtained with a soft handle without verden there is a risk that the fibers will fall out. If acrylic fibers are used as a flat arranged layer, then in particular a liquid binder is used which contains a mixed polymer of acrylonitrile and acrylamide. A suitable binder Iraim can be selected according to the fibers used. To make a product coarse and hard, that is, to make a product that is similar to a conventional product, an additional binder can be applied to the product of the present invention.

Huh carrying out the heat treatment in this manner, two split fiber webs were wound with a width of approximately 7 ^ 0 && at a speed of 200 m / min on a single tree on. Then each of the split fiber webs overhead helical springs were passed, which were arranged in the transverse direction in the direction of travel of the web and in which an atabföraigei * core was inserted. The individual turns of the helical spring penetrated the track. The two ends of a helical spring were led along lines that did not run parallel to each other, the lines being pulled apart laterally to a width of 1.5 s. The webs were then prepared with an emulsion of a mixed polymer of 6096 vinyl acetate and 40% ethylene and then dried to obtain split fiber slabs which

a width of 1.5 m, a split fiber content of 10 g / a and a binder content of 3 s / ^m . They were then wound up. While one of these tracks was running in the longitudinal direction, in a further step the other track was fed horizontally as a weft track from the side with the help of a clamping device and placed over the chain track and cut to a width corresponding to the width of the chain track. The laying took place in such a way that the weft path overlapped each other by half of its width with the previous weft path, so that twice as much in the weft direction came as in the warp direction. Thereafter, the excess cars and chain paths were g3führt gomeinsam a Erhitaungatrommel in order zx connect to each other by heating and pressing, whereby a laminate of warp and weft

Then the cable was first expanded to a width of 150 mm by means of an expander spread out and then spread it out further in the same way as the above sioaltfiberbahnen. Tuck spreading steps were repeated until a cable with a width of 1.5 m and with a largely uniform Thickness had been obtained. The cable was wound onto the eggs in a width of 1.5, with a tape welling was laid diagonally between successive layers to prevent the cable from calibrating during unwinding dissolved.
