Process for the production of a textile product.

The basic idea of flaking on any carrier is known. You can leave it very short or short Textile fibers disordered on a previously with an adhesive » Cloth covered backing fall · The very short or short fibers stick to this glue and you win finally a new product called flocked goods.

If the fibers are very short, or if a fiber dust is used, a suede-like appearance is achieved.

For short fibers, such as from a few millimeters (l rough or 2) it is possible to use these fibers ens such parallel to each other during the low case and to direct perpendicular to the surface of the support, that they of the product according to the

909820/0933

Give a velvety appearance to the adhesive, because then the fibers are perpendicular to the support surface stick out.

One of the known means of straightening the fibers so that they protrude at right angles from the support, consists in dropping these fibers through an electrostatic field.

In this case, apparently every one or two millimeter long fiber with one of the ends will bit the glue come into contact.

The contact area between each fiber and the adhesive must therefore be extremely small because this contact area essentially from the cross-sectional size of the fiber increased by the area of the inserted fiber part consists.

The insertion depth is naturally limited by the strength) of the adhesive layer.

In other words, the total strength is the The textile product obtained depends on the strength of each fiber on the adhesive. This adhesive strength is itself of the properties and the amount of the adhesive dependent »The amount is determined by the manufacturing price and certain physical effects determined, in particular by the weight, rigidity and impermeability of the goods,

Should be made of a double-sided textile product

on one side by a fabric (or • inen felt), on the other side by a flocked fabric is formed, the structure of the flock carrier that forms one side, i.e. the fabric for certain fashion effects, Applications and to achieve Schmuokffekt indicated meet technical conditions

In this way one arrives at the application of a loose or rough structure with numerous hollow brains, which the adhesive would have to cover in order to have a sufficiently strong layer everywhere to accommodate every "falling fiber" to build·

The method according to the invention does not permit only the use of such a structure for the carrier, but also the flaking of longer fibers than with the known ones Process, i.e. of 4 mm long fibers or more, with a relatively small amount of adhesive and without Plugging the cavities through which the textile goods are airtight. It would be casual and annoying to wear. ,

The invention consists in using a latex foam made of natural or synthetic rubber as an adhesive TrSger to apply layer by layer to cause the flaking on this foam, and the foam before vulcanizing to be smashed by blasting.

Latex foams made from natural or synthetic rubber can be produced in very different ways. One uses

909820/0933

H10260

for this purpose, preferably the per se known method of hitting, blowing or other production of Air bubbles in the latex mass, and smeared with this the Owner,

It is well known that the latex foams of nature or synthetic rubber are in a state that can only be compared with Difficulties persist "

There are numerous methods and suggestions for w Stable making such foams during a sufficiently long for the action of heat time for curing and final solidification of the product.

For practicing the method according to the invention do not use these possibilities of stabilization, and, on the contrary, leaves the rubber latex foam in its natural state Condition, so that the foam collapses after a calculated time of a few seconds, so where the bubbles burst one after the other and the foam-like. Texture disappears · One can even break down favor by introducing wetting agents. The resistance of the foam must depend on the Type of carrier, its structure, its fibers, the "" treatment (for crease resistance, water impermeability, o. the like ») can be changed in order to prevent crusting, i.e. the superficial gelling, through which the flocked fibers are held firmly in place

But foam itself does not adhere well to the carrier. Also 909820/0933

H10260

trusting too deeply should also be avoided because this is detrimental to the attachment of the flocked fibers.

The collapse of the foam can be caused by the introduction of stabilizers to a greater or lesser extent below normal amounts or by wetting agents.

The penetration of the adhesive into the carrier must be adjusted so that this adhesive with the Carrier forms a coherent body, while still forming a sufficiently strong surface layer around the To hold on to Pasern.

All the chemical nature of the foam must be chosen in such a way that it maintains the foam-like state for a sufficiently long time

1. "application to the support, 2". »To allow the flaking.

Immediately after this period of time, the foam should burst through the bubbles before vulcanizing, i.e. before collapse when the entire product is introduced into the furnace used for vulcanization.

The results of this procedure are as follows:

1. The finished product consists on the one hand of a textile carrier, on the other hand of flocked fibers, which are relatively long, up to 4 mm and more

909820/0933

can, and this product has a velvety appearance,

The adhesive is invisible, so to speak, i.e. it has no layer thickness and is even on the connecting surface distributed between the flocked fibers and the fibers of the fibers forming the carrier.

2. - The strength of the flocked fibers, ie, the adhesion to the support due to the fact that the initially as a foam adhesive used W abundant is applied, and all the cavities of the carrier face down on which it forms a good layer, and that the fibers the foam-like adhesive will fall and penetrate in such a way that the largest contact areas result from it,

3 "when the bubbles burst and when they collapse of the foam If the adhesive creeps through capillarity on the flocked fibers and also on the fibers of the Textile material, whereby it creates the connection between all fibers in the best possible way.

4. * · The goods can be used for clothing because it is light, pliable and breathable. Dry degreasing with solvents can be done after incorporation thermosetting resins can be effected in the latex mixture. By the way, these resins also make the connection between the adhesive on the one hand, the fibers of the carrier and the flocked fibers on the other.

For the sake of better understanding, this is 909820/0933

inventive method below with reference to the Drawing described in more detail

Fig. 1 is a very enlarged sectional view of the fabric used as a carrier.

Fig. 2 is a similar view of the same fabric immediately after the foam layer is applied and after flaking the fibers,

Figure 3 is a similar view after the burst ier foam blowing and after vulcanizing "

The fabric shown consists of warp thread and weft thread 2 with a loose structure, their fibers 3 and Form 4 large cavities.

The adhesive is applied as a relatively thick layer 5 covering the entire space between the Fibers 3, 4 of the FKden 1 and 2 fills, and a fairly large height on the corresponding side of the duroh these Threads formed tissue reached.

The flocked fibers 6 penetrate parallel to each other in this foam layer, namely up to a relatively large part of their height.

After a relatively short period of time, the foam collapses and the adhesive forms droplets 7, which by capillarity on one or more Adhere to the flocked fibers 3 and 4 of the threads 1 and 2 of the carrier "

The flocked fibers 6 are up to a 909820/0933

rather large thickness of a film-like adhesive sheet envelops, which it holds firmly on the carrier. Nevertheless, the one made in this way remains Textiles permeable to air.
