Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention comprises a loop-shaped element which is provided with a number of protruding loops as fastening means on its working surface and a number of hooks as fastening means on its working surface. a hook-shaped element having projecting means in the form of a barb-shaped element which engages the plurality of loops of the loop-shaped element when the working surfaces of both elements are pressed together to effect attachment of both elements; The present invention relates to a textile surface-adhering fixture.

[Conventional technology]

Adhesive fixtures of this type are known. As a means of hooking, a plurality of loops or stubs may be used, said loops being cut transversely and opened so that the long part of the loop forms the hook, while the end of the stub is attached to the mushroom. It is thickened into a shape. These hooks and stumps each engage a plurality of loops on the other element of the attachment fixture if the two working surfaces of the two elements are pressed together in face-to-face relationship.

[Problems to be solved by the invention and means for solving them]

The present invention relates to a textile fixation product as an element of a surface-adhesive fixation device. This type of textile product comprises a base fabric with at least five working surfaces from which a number of fastening means protrude, the fastening means being protruding loops or hook-shaped protrusions formed from a pile system. It has the shape of a means.

Such a fixing product together with other fixing products comprising a working surface with corresponding fixing means forms a surface-adhering fixture. In addition to the base cloth 9 of the textile fastening product, the other fastening product may also have a plastic foil, from which a corresponding fastening means integral with the foil projects.

Nofil systems for forming hooks are generally monofilaments of polyamide fibers, while /9 systems for forming mushroom-shaped expanded stocks are made from I-lipropylene monofilaments.

The object of the present invention is to achieve a substantial expansion of the field of application of the known textile attachment fixtures and thereby to obtain advantages in a wide variety of applications.

This object is achieved according to the invention, in which at least the filament forming the fixing means is coated with a thin layer of metal. In an advantageous embodiment, all surfaces of the element are coated with a thin metal layer.

As a result of extensive experimentation, the textile fasteners and fixtures of the present invention can withstand much higher temperatures than previously known textile fasteners and fasteners. For example, polyamide products oxidize at 170°C to 200°C, causing them to crack and become brittle. However, fixtures and fixtures coated according to the present invention can withstand temperatures 40°C to 50°C higher than previously. This can probably be explained by the fact that the thin metal layer protects the plastic material from contact with atmospheric oxygen. The above-mentioned improved resistance to temperature extends the field of application of textile adhesives to include areas such as retention fabrics against adverse conditions, filter elements in combustion and heating equipment, and the like. Filter elements in combustion and heating devices must be replaceable. The installation and removal of such filter elements is made very simple by using the fixture according to the invention. This is because during installation it is sufficient to press the filter element with which one element of the attachment fixture is attached onto the other element of the fixture, which is attached to the base of the device, and it is equally easy to remove it. can.

The metal coating makes the textile adhesive fasteners according to the invention electrically good conductors, so that these textile adhesive fasteners can be used in areas where easy contact is required in low voltage circuits or where electrical charges are handled. It can be used in fields that must be removed. It can also have a particularly wide range of applications in the field of medical technology, for example, the textile attachment device according to the invention can be used in earthing sleeves for blood pressure and pulse measurements, insulating materials such as wheelchairs, seats and seat shells. It can be used to electrically connect bodies, etc. by an easily removable method.

Still other fields of application are, for example, electronic equipment equipped with easily insertable, removable printed circuit boards or microchips. The fastener according to the invention can be used for mechanical fastening operations of mounted printed circuit boards, thereby providing momentary grounding of insulating parts of the printed circuit board to prevent any electrostatic charging. .

A particular advantage of the fastener according to the invention is that both elements can retain the mechanical properties possessed by the textile material, i.e. by selecting the type of filament, the required softness and flexibility; However, it will contribute to a very wide range of application fields.

〔Example〕

The invention will now be described in detail with reference to the accompanying drawings, which illustrate one embodiment of the invention.

The surface-adhesive fixture shown in FIG. 1 consists of two elements 1 and 2. Element 1 is a textile fastening article having on its working side a number of protruding fastening means in the form of a loop;
According to FIG. 1, the active side surface is arranged on the underside of a textile base fabric, for example a woven or knitted base fabric. Since such fastening means are generally known, in FIG. 1 said protruding fastening means are only shown very schematically.

The fastening element 2 is also a textile fastening article, which comprises a textile base fabric, for example a woven or silk fabric, from which a plurality of hook-shaped or mushroom-shaped fastening means protrude. Consists of. Since such fixing means for said textile fixing articles are also generally known, the fourth
In the figures the fixing means are shown roughly. Said hook-shaped fastening means are made by cutting open one leg of each of a plurality of closely projecting loops, so that the other longer leg forms a hook.

The mushroom-shaped fastening means are formed by the free ends of a plurality of upright stumps, which are thickened by melting to form a mushroom condyle.

Both elements of the fixture are coated with a layer of electrically conductive metal, such as copper, aluminum or silver, by high vacuum deposition. The thickness of the metal layer is only a few microns.

FIG. 2 shows a cross section of a monofilament 3 surrounded by a metal layer 4. In FIG. Such a monochrome or filament is used to form the hook-shaped or mushroom-shaped fixing means. Said metal coating 4 is preferably applied after the fixing element has already been completed in order to avoid coating the metal coating with finishing agents etc. The monofilament 3 may be made of polyamide, 4-lipropylene or other plastic materials. It would be good if you could. In the case of the hook-shaped fastening means, the monofilament 3 is generally made of polyamide, and in the case of the mushroom-shaped fastening means, it is made of polypropylene.

Figure 3 shows element 2 with loops of a textile surface-adhesive fixture.
Used for multiple loops. FIG. 5 is a cross-sectional view of multifilament 5. FIG. These filaments 5 are also coated with said metal layer 4.

After the fixture is completed, each element of the fixture is coated with the metal layer 4 using high vacuum deposition. A plurality of multifilaments forming a woven or knitted fibrous base fabric is also commonly used. Covered by said layer 4. Said layer 4 protects the filament from oxidation, so that said elements of the fixture can withstand very high temperatures, even compared to known textile fixtures of this type. Furthermore, elements 1 and 2 of the fixture are electrically good conductors, so that the fixture can function as an electrical switch that can be easily switched on and off. .

The layer produced by the high vacuum evaporation process is very uniform and thin, so that the mechanical properties of elements 1 and 2 of the fixture and of the entire fixture formed by these elements are are not affected in the slightest by these coatings.

The features appearing from the foregoing description and the accompanying drawings may be considered as further embodiments of the invention IN, even if they are not specifically mentioned9 or in the claims. b-<tt-t'4
