The present invention relates to a composite which is intended for use as an insert material, in particular as a lower collar material and in which a wool or semi-wool fleece is needled onto a loosely set fabric, e.g. half linen.

Bs has already been proposed to use as a base fabric of such a composite, a diagonal weave, with the fibers of the web are entangled and wherein felted the \ during needle punching operation through the tissue of beaten fiber ends of the mat in random orientation under connection with the diagonal tissue to a third layer.

The problem H The present innovation is to use one as an insert material to create particularly suitable composite material that, depending on the outer material to be processed with the composite material, both ' can be used on both sides. The composite of the invention

should therefore be practically the same on both sides

The characteristic of the innovation according to the model consists i in that · that in the case of a composite material defined at the outset, on the side facing away from the needled-on fleece Fabric another wool or semi-wool fleece arranged '■; is, which with the protruding through the fabric ·! (needled through) piping of the first-mentioned fleece common felting and fulling is matted. ! '■ -

The two fleece layers can be differentiated here

The composite material according to the pattern can additionally in itself; be equipped in a known manner. This finish can be used e.g. in a post-treatment with plastic, starch or the like exist. *;

During the production of the composite material according to the pattern, a semi-wool fleece is needled onto a linen or half-linen web, for example, in accordance with the proposal described at the beginning. Instead of linen or half-linen, any loosely set woven or knitted fabric can be used, including, for example, synthetic active ingredients. Subsequent to 'ß the needling is on the side facing away from the fleece - ^;

of half-linen another layer of wool or half-wool fleece applied, which optionally and often in a very desirable manner may have a different color.

The color differences between the two nonwovens can be either | through the use of pre-dyed raw materials or by making them "Be that the two nonwovens have different fiber compositions and thus when after-; "Obtain different color effects from wearable piece dyeing".

Die.Verbindung of the individual layers is effected by moving ^up: felting and fulling. During this process, the felting takes place once, that is, the "solidification and entangling of the fibers," caused by the needling through the linen web: ■ dAUrGhgggtobenen fibers of the first-mentioned footrest * on the underside of the linen web and at the same time the connection of the 'the' other side ^issued: second "felt piece with these fibers of the first felt _s piece, it being understood that the two nonwoven layers f are entangled in itself (eg, random orientation of the fiber ends).

It. is also possible within the scope of the present innovation,

to form the two fleeces approximately the same color and then to connect them to one another in the manner described above to form a composite. The two layers of nonwoven fabric can have different properties.

In, the drawing is an embodiment of the Innovation presented.

Here, an upper wool felt layer 1 is shown, which is made of a half-linen layer 2 is arranged. Below this; Half-linen layer 2 is another wool felt layer 3 Layer 1 is made by needling in the direction of arrow 4

These fibers are entangled after application of the layer 3 by JMIT 'j \ felting and fulling do so. that all three layers are firmly connected to each other. i. ·.
