Pile fabric for outer clothing purposes

The innovation relates to a pile fabric for outerwear purposes, consisting of a base fabric or knitted fabric, a pole, preferably made of synthetic fibers, and a back, which is surrounded by an outer, closed Plastic layer, e.g. formed from polyurethane.

It is already known to coat pile fabrics or pile knitted fabrics with polyurethane on their back. One The known tufting process provides an economic opportunity for this. The back of a But tufted fabric is very uneven. This is based on the fact that the yarns are passed through a fabric backing needled through, with pronounced rows of elevations and depressions on the back of the fabric develop. The loops of the pile-forming yarn are also very loosely attached to the base fabric, see above that it has hitherto been necessary to increase the pull-out strength of the loops. A back app-r.tur, through However, the fact that the loops could be fixed is not enough to level out the bumps, it is unless the coating is made so thick, such as in carpet tufted fabrics, that use for outerwear is no longer possible because the handle is too stiff.

On the other hand, one can, despite the in itself inadequate Loop pull-out strength of a tufted fabric that has not been finished in the back of this fabric by mechanical means Design processing so that the bumps on the back of the fabric largely disappear and one thin plastic coating can be applied, which does not impair the pliability of the goods required for outer clothing purposes. the The desired pull-out strength of the loops occurs when the pile-forming yarn is tufted is needled in loops into the base fabric and those on the top of the fabric Loops are roughened or torn to create a mechanical felting, while the reverse side of the fabric roughened, sheared and, if necessary, sanded before the plastic layer is applied is.

The goods produced in this way, however, do not yet have the voluminous, soft one that is often requested leather-like handle. The task of the innovation is therefore to produce a pile fabric of the type mentioned above to be improved in a simple way so that they are hardly or not too in the grip of high-quality, soft leather is different. This object is achieved in a surprisingly simple manner in that between pile fabric backs and the plastic layer is preferably solvent-resistant with the backing of the pile fabric Lamination connected foam and / or fleece intermediate layer is arranged. Already with one extremely thin intermediate layer about 0.5 mm thick, the desired improvement in the handle occurs one.

The intermediate layer can consist only of polyurethane foam or only of a fleece, preferably a fleece made of crimped tangled fibers. But it is also possible to have a foam and a Vliesiage combined intermediate layer to be attached in which the fiber or melt spunbonded nonwoven to the The back of the foam layer rests, that is, between the foam and the one that covers the back continuous plastic layer is located.

The innovation is explained in more detail with reference to the drawing. It shows:

Fig. 1 is a vertical section through the pile fabric after the needling of the pile-forming yarn in the tufting process,

Pig. 2 is a top view of FIG. 1, rear side,

Pig. 3 one of the pig. 1 corresponding sectional view of the pile fabric after roughening or tearing open the pile-forming yarn on both sides of the fabric,

Pig. 6 shows another embodiment of FIG

Innovation also shown in vertical section.

In FIGS. 1 and 2, the base fabric is indicated at 1. The pile-forming yarn is needle-punched in loops into the base fabric 1 using the tufting method. The loops protruding over the top of the fabric are denoted by 2; those on the wrong side of the fabric Sling parts with 3.

In a subsequent processing step, the loops 2 on the upper side of the fabric become the pile-forming Yarn roughened or torn and mechanically matted. The pile-forming yarn thereby takes about the in Pig. 3 at 2a indicated shape. Then the loop parts 3 also roughened so that they have the shape indicated in Fig. 3 at 3a. By roughening or The pile-forming yarn is sufficiently resistant to pulling out of the loops 2 and the subsequent mechanical entanglement become, so that when roughening the loop parts 3 on the underside, it does not pass through the base fabric pulls through. The roughened underside of the fabric can now be sheared and possibly sanded so that a sufficiently smooth surface results.

According to FIG. 4, a thin, i.e. about 0.5 mm thick layer 5 of polyurethane foam is placed on the smoothed reverse side of the goods on laminated, which on the outside imitate the natural leather-ü de plastic layer 4, preferably made of polyurethane, carries.

The latter plastic layer is first applied to the thin polyurethane foam layer using the reverse process and then this by preferably solvent-resistant lamination with the pretreated pile fabric backing been connected.

As a variant of this described arrangement, the arrangement of a polyurethane foam layer is associated to mention with the leather-like outer skin, but not a prefabricated polyurethane foam sheet What is used is »rather this foam intermediate layer is generated in situ by applying a foamable mixture. First of all, the imitation of natural leather will be used here Outer layer formed by the reverse process, applied to the foamable mixture and then the prepared pile fabric is applied.

The latter arrangement is particularly suitable to compensate for any unevenness in the back of the goods and if necessary, shorten or omit the roughing and felting treatment of the back of the goods.

According to Fig. 5, the intermediate layer between the roughened and sheared loop parts 3a and the plastic layer 4 from a base fabric side Plastic foam layer 5 and a thin fleece 6 facing the back are made. The fleece 6 forms a Paser or melt-spun fleece.

Fig. 6 shows a further embodiment of the innovation. Here, the entire intermediate layer consists of a fleece 6, preferably of crimped random fibers, wherein the intermediate fleece layer is connected to the pile fabric back 3a by lamination.

Example :

A fabric made of 34/1 cotton in the warp and 5o / 2 cotton in the weft is made with 40 stitches per 10 cm

Pile-forming 8/1 Dralon yarn needled.

After the fabric has been dyed, the loops are roughened or roughened on the right-hand side of the fabric with a hoisting machine. torn open. A mechanical felting of the resulting pile is then caused by the The circumferential speed of the roughing roller is below the speed of the roughing drum.

In the condition of the goods achieved in this way, it is now possible to use the left side of the goods intended for the coating to rough, to shear and possibly to sand, so that such a uniform surface arises that it is suitable for the coating can be used. The coating consists e.g. of a thin polyurethane foam layer (Thickness approx. 0.5 mm), which has a thin, closed polyurethane layer on its outside (solids content the outer layer approx. 5o - 15o g / m.

Deviations up or down are of course possible.)

The purpose of arranging the intermediate layer between the pile fabric backing and the polyurethane outer layer is the product to give a voluminous, soft leather-like handle.

In addition, the polyurethane foam layer can be on the outside still be laminated with a thin fiber or melt-spun fleece, on which the polyurethane layer is then is appropriate. An intermediate layer can also be used instead of the polyurethane foam layer o, 5 mm thick fleece layer, preferably consisting of a crimped tangled fleece, be arranged on which

then the polyurethane layer is attached. The fleece is connected to the back of the pile fabric by lamination.

Applying the polyurethane coating on the outside the intermediate layer is preferably carried out according to the so-called reversal process. The polyurethane layer expediently has one resulting from embossing by means of an embossing roller or from the imprint of the reversal paper Leather grain and color pigments. The connection of the The polyurethane foam layer with the reverse side of the pile is made according to the known laminating techniques, i.e. through Flame or adhesive lamination. In the case of applying a non-prefabricated foam layer by foaming, of course, there is no need to clad the foam layer.
