  • Adhesive elements free and can later with adhesive elements of another adhesive fastener part, for example in the form of a loop band, forming a usual adhesive fastener.
  • upholstery materials can be made Define foamed upholstery parts of a motor vehicle seat or passenger seat or rotating components, for example in the form of grinding wheels, with Tool holders on conventional grinding machines and devices connect.
  • the foam material mentioned can depend on each object to be molded must be extremely fluid and viscosities have, which are in the range of water or below. It has now shown that when using loop and loop material as Lanyard or the like when using adhesive fleece. the in itself open loops are not completely penetrated by the foam material but rather form a kind of barrier for this that Prevents the penetration of the foam material.
  • the curing or baking process for the foam material depends on the Transition points between the loop material and the foam to blowholes, thus to gaseous hollow inclusions, which form a firm connection counteract between the adhesive fastener part and the foam material. Because of the reduced strength of the connection between Adhesive fastener parts and foam material are particularly common during long-term use to release the connection and the adhesive fastener part tears out of the foam material, making it unusable overall of the entire component, for example in the form of a Vehicle seat or a grinding wheel holder.
  • EP-A-0809 952 discloses a generic fastener part, which is made of a biodegradable plastic material.
  • the individual adhesive elements are adjacent to each other in the known solution opposite double hook elements formed on their a reinforcing rib each on the side facing the tape-like fastener part exhibit.

  • the object of the invention is to further improve an adhesive closure part in such a way that a secure and high-strength connection between the adhesive closure part and the foam material used in each case can be achieved. Furthermore, the invention is based on the object of providing a method for producing a corresponding adhesive closure part and an apparatus for using this method. Such a task is solved by an adhesive fastener part with the features of claim 1, a method with the features of claim 3 and a device with the features of claim 5.
  • the adhesive medium is fluorine, it comes between the thus treated fastener part and the respective foam material to a high-strength connection that is difficult to solve, so that there is a long-term connection between the fastener part and the later foam body results. Due to the adhesive medium that penetrates into the adhesive fastener part and is introduced into it in this way, a surface-selective chemical reaction is generated on the adhesive fastener part, which leads to the good connection values with the foam material. Compared to the known solutions, the adhesive medium is not applied separately to the adhesive fastener material as a type of adhesive layer, but rather an integral part of the adhesive fastener.
  • fluorine is used as the gaseous adhesive medium to be introduced, preferably with adhesive fastener parts made of polyolefin material
  • the of the polyolefin surface are determined by fluorine atoms replaced. This substitution reaction takes place at room temperature. It is not Start or initial reaction required. Now partially on the surface fluorinated hydrocarbons behave completely differently than the previous one Basic material of the fastener part. Because of its high electronegativity the fluorine atom tries to fill its outer electron shells. To become electrons from neighboring carbon and hydrogen atoms deducted.
  • An advantage of the fluorine treatment is a reliable adhesion to all polyolefins with an otherwise low surface tension, whereby there is an even penetration with the fluorine material, so that even complicated geometries and surfaces including undercuts, cavities, inner surfaces or the like. receive a fluorine treatment that promotes liability.
  • a sufficient number of polar components must be ensured, with polar components of 40 mN / m 2 and more being achievable with polyolefin materials.
  • the fluorine is in a nitrogen atmosphere applied, the fluorine input continuously or discontinuously, that is with running or upright fastener part, be carried out well can.
  • the storage of fluorine nitrogen mixtures in high pressure cylinders has been around since state of the art for many years and what the toxicology of the matter As far as gas mixtures are concerned, this is in safety data sheets and DIN standards relevant and safely regulated, so that even in large-scale application health risks are not to be feared.
  • the adhesive fastener parts to be treated in one Vacuum chamber exposed to the fluorine nitrogen gas atmosphere Due to the Vacuum chamber is avoided with certainty that the fluorine nitrogen gas mixture unintentionally can emerge from the device.
  • the device in question can carry out a batch process, in which the adhesive fastener parts to be treated for a predetermined Time to remain stationary in the device or continuously, at which Continuous entry and exit of a continuous belt or a surface of an adhesive fastener part.
  • the adhesive fastener part presented below is used in particular for foaming upholstery parts of vehicle seats (not shown) during their manufacture.
  • the band-like or sheet-like fastener part has on one side adhesive elements 10 for connecting to corresponding adhesive elements of another fastener part (not shown) to form a customary fastener.

  • a connecting means is provided for establishing a connection with the respective foam material, for example in the form of a polyurethane foam, which is introduced into the rear of the fastener part.
  • the adhesive fastener part itself is formed from a polyolefin plastic material
  • polyolefins generally being the general term for polymers of the general structure represent in which R 1 is mostly hydrogen and R 2 is a straight-chain or branched saturated aliphatic or a cycloaliphatic group for hydrogen.
  • polymers with aromatic groups for example the phenyl radical (R 2 C 6 H 5 ), see polystyrene) are also classed as polyolefins.
  • Polyolefins with great technical importance in the field of fasteners are, for example, polyethylenes, polypropylenes, polybutenes, the occasionally misleading also called polybutylenes or polybutenes, as well as polyisobutenes and poly (4-methyl-1-pentene) s, polymers of the higher ⁇ -olefins, e.g. However, poly (1-hexene), poly (1-octene) or poly (1-octadecene) have So far, only very limited technical application has been found in this field.
  • the polyolefins also include copolymers of different olefins, e.g. that of ethylene with propylene.
  • the adhesive medium is preferably fluorine and is introduced into the adhesive closure part via subsequent fluorination.
  • the fluorine mentioned is used as F 2 and therefore as a gas, preferably in a nitrogen atmosphere.
