Description

In der Patentanmeldung H 38613IV c/8 k (deutsche Auslegeschrift 1276 590) ist bereits ein Verfahren zur Verbesserung der Knitter-, Reiß- und Scheuerfestigkeit von cellulosehaltigen! Textilgut durch ionisierende Strahlung vorgeschlagen worden, wonach mindestens 20% und vorzugsweise 30 bis 40% Feuchtigkeit aufweisendes Textilgut in Abwesenheit eines Modifizierungsmittels für Cellulose mit einer Totaldosis von 103 bis 2 X 106 REP bestrahlt wird und während der Bestrahlung bzw. nachfolgend durch Erwärmen auf mindestens 30° C, vorzugsweise 50 bis 80° C die C-Atome der Molekülketten vernetzt werden.In the patent application H 38613IV c / 8 k (German Auslegeschrift 1276 590) there is already a method for improving the crease, tear and abrasion resistance of cellulose-containing! Textile material has been proposed by ionizing radiation, according to which at least 20% and preferably 30 to 40% moisture-containing textile material is irradiated in the absence of a modifier for cellulose with a total dose of 10 3 to 2 X 10 6 REP and during the irradiation or subsequently by heating at least 30 ° C, preferably 50 to 80 ° C, the carbon atoms of the molecular chains are crosslinked.

Es wurde nun gefunden, daß besonders günstige Voraussetzungen für die Vernetzung und einen mögliehst geringen Abbau der Cellulose erzielt werden, wenn das Textilgut der Einwirkung beschleunigter Elektronen mit einer Teilchenenergie von weniger als 1 Million Elektronenvolt (MeV), insbesondere zwischen 0,05 bis 0,6 MeV unterworfen wird.It has now been found that particularly favorable conditions for networking and one possible low cellulose degradation can be achieved if the textile material accelerates the action Electrons with a particle energy of less than 1 million electron volts (MeV), in particular is subjected to between 0.05 and 0.6 MeV.

Die ^-Strahlen können den üblichen Elektronenbeschleunigungsapparaten, z. B. Kaskaden-, Van de Graaf- oder Linearbeschleunigern, entnommen werden. Es können aber auch radioaktive Substanzen, z. B. 90 Sr, das ^-Strahlen mit einer Teilchenenergie von 0,6MeV aussendet, oder Promethium 147, dessen /3-Strahlung eine Teilchenenergie von 0,223 MeV hat, verwendet werden. Auch gasförmige radioaktive Strahlenquellen, wie z.B. Krypton 85, dessen /!-Strahlung eine Teilchenenergie von 0,67MeV aufweist, kommen in Betracht.The ^ -ray can the usual electron accelerators, z. B. cascade, Van de Graaf or linear accelerators can be taken. But it can also radioactive substances such. B. 90 Sr, which emits ^ rays with a particle energy of 0.6 MeV, or Promethium 147, whose / 3 radiation has a particle energy of 0.223 MeV, can be used. Gaseous radioactive radiation sources, such as krypton 85, whose /! Radiation has a particle energy of 0.67 MeV, can also be used.

Das erfindungsgemäße Verfahren läßt sich auf Textilgut aller Art, insbesondere Flächengebilden, anwenden. Es kommen in erster Linie Gewebe, Gewirke oder Faservliese aus nativer Cellulose, wie Baumwolle, oder aus regenerierter Cellulose oder solche Flächengebilde, enthaltend Fasern aus natürlicher und regenerierter Cellulose, in Betracht. Das Verfahren läßt sich aber auch auf Textilgarnen, -fäden oder -zwirnen anwenden. Bei erfindungsgemäß behandelten Textilgeweben wird gegenüber dem Ausgangsmaterial eine Zunahme der Knitterfestigkeit und der Scheuerfestigkeit bei ungefähr gleichbleibender Reißfestigkeit erreicht. Bei Feingeweben aus relativ hochgedrehten Garnen wie Voile und Marquisette, die eine starke Tendenz zum Schrumpfen haben, wird eine Schrumpffestigkeit gegenüber Waschen und damit eine gute Dimensionsstabilität erzielt. The method according to the invention can be applied to all types of textile material, in particular flat structures. There are primarily woven, knitted or non-woven fabrics made from native cellulose, such as Cotton, or made of regenerated cellulose or such flat structures, containing fibers made of natural and regenerated cellulose. The process can also be used on textile yarns, use threads or twists. In the case of textile fabrics treated according to the invention, opposite an increase in crease resistance and abrasion resistance of approx constant tear strength achieved. For fine fabrics made from relatively high-twisted yarns such as voile and marquisettes, which have a strong tendency to shrink, will have a shrinkage resistance compared to washing and thus achieved good dimensional stability.

Die Erfindung ist an Hand der nachfolgenden Ausführungsbeispiele näher erläutert:The invention is explained in more detail using the following exemplary embodiments:

Beispiel 1example 1

Ein Imitatpopeline, entschlichtet und gebleicht, wird einer Elektronenstrahlung mit einer Teilchenenergie zwischen 0,08 und 0,15 MeV ausgesetzt und eine Gesamtdosis zwischen 105 und 10e REP eingestrahlt. Anschließend wird das Gewebe mittels Wasserdampf 10 Minuten auf 80° C erhitzt. Die, Reißfestigkeiten sind nicht vermindert, dagegen die Scheuerfestigkeiten und Knitterfestigkeiten verbessert.An imitation popeline, desized and bleached, is exposed to electron radiation with a particle energy between 0.08 and 0.15 MeV and a total dose of between 10 5 and 10 e REP is irradiated. The fabric is then heated to 80 ° C for 10 minutes using steam. The tear strengths are not reduced, but the abrasion strengths and crease strengths are improved.

Beispiel 2Example 2

Das Gewebe wird sodann mittels eines Wannluftstromes während 5 Minuten auf 60° C erwärmt. Das Gewebe zeigt verminderte Schrumpfung.Full cotton voile, desized and bleached, is exposed to electron beams with a particle energy between 0.08 MeV and 0.15 MeV in the presence of air at 20 ° C and a total dose of 10 5 to 10 6 REP is irradiated. The tissue is then heated to 60 ° C. for 5 minutes by means of a stream of air. The fabric shows reduced shrinkage.
