The invention relates to a method for local irradiation, in particular for the local irradiation of surface structures high-polymer materials, preferably textile fabrics.

HIs ist bekannt, lokale Bestrahlungen durch Ausblenden eines homogenen strahlungsrelcies, insbesondere eines Elektronenstrahlungsfeldes, mittels stationärer oder bewegter Schablonen zu erreichen. Weiter ist bekannt, lokale Bestrahlungseffekte an in einem Homogenen Strahlungsfeld bestrahlten hochpolymeren "Werkstoffen dadurch zu erreichen, daß nach der homogenen Bestrahlung, insbesondere mit Elektronenstrahlen, die durch das Eestrahlen gebildeten reaktionsfähigen Spezies (vorzugsweise Haciikale) lokal durch radikalzerstörende Medien vernichtet werden. Ss ist weiterhin bekannt, lokale Bestrahlungseffekte durch Steuerung des Elektronenstrahles an der Quelle zu erreichen, It is known that local irradiations can be achieved by masking out a homogeneous radiation relcies, in particular an electron radiation field, by means of stationary or moving templates. It is also known that local irradiation effects can be achieved on highly polymeric materials irradiated in a homogeneous radiation field in that, after the homogeneous irradiation, in particular with electron beams, the reactive species (preferably aciicals) formed by the irradiation are locally destroyed by media that destroy radicals known to achieve local irradiation effects by controlling the electron beam at the source,

Der Erfindung liegt die Aufgabe zugrunde, verschiedene ötruktureffekte ohne Auswechselung der strukturgebenden Elemente zu erreichen,The invention is based on the object, various to achieve structural effects without changing the structural elements,

Erfindungsgemäß wir α die Aufgabe dadurch gelöst, ciaß das Flächengebilde mit einem durch elektrische und/oder magnetische Felder veränderten homogenen Strahlern: ela, insbesondere Elektronenstrahlenreld, bestrahlt wird. Zweckmäßig ist es, ferromagnetische Substanzen oder magnetische und/oder unmagnetische Formkörper auf das zu bestrahlende .Flächengebilde aufzubringen. Vorteilhaft ist es, als Formkörper zylindrische Magnete und/oder ötahlkugem und/oder magnetische Plattchen aufzubringen. Weiter ist es zweckmäßig, auf das zu bestrahlende Flächengebilde voneinander isoliert und eleictrisch. miteinander verbundene Metailstäbe aufzubringen.According to the invention, the object is achieved by ciaß that Flat structure with a homogeneous radiator modified by electrical and / or magnetic fields: ela, in particular Electron beam field, is irradiated. It is useful to use ferromagnetic or magnetic substances and / or non-magnetic shaped bodies to be applied to the planar structure to be irradiated. It is advantageous as a molded body to apply cylindrical magnets and / or ötahlkugem and / or magnetic plates. It is also useful isolated from each other and electrical to the surface structure to be irradiated. interconnected metal rods to raise.

Die Erfindung soll nachstehend an einigen Ausiünrungsbeispielen näner erläutert werden. In der dazugehörigen Zeichnung zeigen Fig. ί das Transportband mit Querstäben unu Fig. 2 die Abwickelung des Transportbandes.The invention is illustrated below on the basis of some embodiments will be explained in more detail. In the accompanying drawing, Fig. Ί shows the conveyor belt with cross bars unu Fig. 2 shows the unwinding of the conveyor belt.

Beispiel 1 ί Aui einem unter dem Scanner eines Elektronenbeschleunigers angeordneten umlaufenden Band sind zylindrische Magnete angeordnet, entsprechend dem Verlaur der Magnetieider werden die Elektronenstrahlen abgelenkt und trefien auf das synchron mit dem mit Magneten bestückten Band laufend Polyamidseiden-Kettengewirke. Das auf diese Weise lokal bestrahlte Polyamidseiden_Kettengewirke wird anschließend mit einer 2O-?äigen Akrylamidlösung kontaktiert, v/o durch ein Aufpfropfen von Akrylamid auf die bestrahlten bbellen erfolgt und dadurch ein ütruktureffekt eintritt.Example 1 ί Aui one under the scanner of an electron accelerator arranged circumferential belt, cylindrical magnets are arranged, corresponding to the Verlaur of the Magnetieider the electron beams are deflected and hit the belt, which is equipped with magnets, synchronously ongoing polyamide silk warp knitted fabrics. The locally irradiated polyamide silk warp knitted fabric is then contacted with a 2O-aque acrylamide solution, v / o is carried out by grafting acrylic amide onto the irradiated cells, which results in a structural effect.

Beispiel 'dx Zusatzlich zu dem im Beispiel 1 genannten Magneten werden auf das umlaufende Band Stahlkugeln aufgebracht. Das Gewirke wird wie Beispiel ί behandelt.Example 'dx In addition to the magnet mentioned in Example 1, steel balls are applied to the circumferential belt. The knitted fabric is treated like example ί.

Beispiel 3: Auf· ein Polyamid-Kettengewirke v/erden aus einem Behälter vor dem Bestrahlen magnetische Plattcnen, üie quaciratiscn rund oaer besondere gestalten sind, auf aas umlaufende Band gebracht. Jjurch Anein^nderlegen entstehen kreuziörmige oder andere Muster Dei WeiterDehandiung v/ie nach Beispiel ι.Example 3: On a polyamide warp knitted fabric from a Magnetic plates, quacirated before irradiating the container around oaer special designs are, on aas circumferential Tape brought. By placing them next to each other, cross-shaped ones are created or other patterns of further handling v / ie after Example ι.

Beispiel '+■: Auf uem umlaufenden Band ί (jrig.1) wer den metallene ^uerstäDe 2 isoliert voneinander angeordnet, die synchron mit dem Gewirke unter dem Scanner 3 "Vorbeigeführt werden. Die Querstäbe 2 sind gemäß Fig. 2 elektrisch miteinander verbunden. Die aus dem Beschleuniger austretenden Elektronen von 0,5 MeV werden bei einem Strom von 5>C A durch das sich um jeden Stab ausbildende Magnetfeld, bei einem Stababstand von 30 mm, mit einem durchschnittlichen iirümmungsradius Von etv/a 70 mm aus ihrer Richtung abgelenkt, so daß durch die entgegengesetzte Stromflußrichtung streifenv/eise mehr oder weniger Elektronen das Gewebe treffen, wodurch nach Behandlung gemäß Beispiel 1 ein Struktureffekt ersielt wird. Die beiden Dioden 4 lassen den Strom nur durch die oberen Stäbe zwischen den Kontakten 5 fließen. Eine derartige Verfahrensweise hat gegenüber der Anwendung von Stäben als Abdeckelemente den Vorteil, daß durch die Größe des Stromes ;die Streifenbreite der bestrahlten Streifen in weiten Grenzen geregelt werden kann, ohne die Abdeckelemente auswechseln zu müssen.Example '+ ■: On the revolving belt ί (jrig.1) the metal extrusions 2 are arranged isolated from one another, which are passed synchronously with the knitted fabric under the scanner 3 ". The cross bars 2 are electrically connected to one another as shown in FIG. The electrons of 0.5 MeV emerging from the accelerator are deflected out of their direction with a current of 5> CA by the magnetic field forming around each rod, at a rod spacing of 30 mm, with an average radius of curvature of about 70 mm, so that more or fewer electrons hit the tissue in stripes due to the opposite current flow direction, whereby a structural effect is obtained after treatment according to example 1. The two diodes 4 allow the current to flow only through the upper rods between the contacts 5. Such a procedure has compared to the use of rods as cover elements, the advantage that due to the size of the current ; En limits can be regulated without having to replace the cover elements.
