Description

  

  Verfahren zur Verbesserung der mechanischen Eigenschaften  von     cellulosehaltigem        Textilgut       Im Hauptpatent ist ein Verfahren zur Verbes  serung der mechanischen Eigenschaften von     cellu-          losehaltigem    Textilgut mit Hilfe ionisierender Strah  len beschrieben.

   Dieses ist dadurch gekennzeichnet,  dass ein gegebenenfalls modifiziertes     cellulosehaltiges     Textilgut in Abwesenheit eines     Modifizierungsmittels     für die     Cellulose        während    und/oder nach der Be  strahlung zum Zwecke einer     Vernetzung    von     C-Ato-          men    der Molekülketten auf mindestens 30 C er  wärmt wird.  



  Es ist bekannt, Textilgewebe aus natürlicher oder  regenerierter     Cellulose    zum Zwecke der Dimensions  stabilisierung mit der Lösung eines     kondensierbaren     Kunstharzes     in        Gegenwart    eines     Katalysators    zu  imprägnieren, gegebenenfalls vorzutrocknen und  kurze Zeit über 100  C zu erhitzen zwecks Konden  sation des Kunstharzes. Da diese Methode eine  ziemlich starke Herabsetzung der Faserfestigkeit be  wirkt, wird sie hauptsächlich bei relativ groben Ge  weben angewandt. Es besteht aber anderseits bei  Feingeweben aus relativ hoch gedrehten Garnen, die  eine starke Tendenz zum Schrumpfen haben, wie  z. B.

   Voile und     Marquisette,    ein namhaftes Bedürf  nis, eine Dimensionsstabilisierung erzielen zu können.  



  Es ist zwar bekannt, Voile und     Marquisette    mit  tels     Aminoplasten    zu stabilisieren, wobei aber die  Harzeinlagerung zufolge der Herabsetzung der Faser  festigkeit sehr begrenzt ist. Der erzielte Stabilisie  rungseffekt bringt sowohl eine merkliche Verminde  rung der Schrumpftendenz mit sich, aber die dabei  erzielten Resultate sind     unbefriedigend,    da bei der  noch verbleibenden Restschrumpfung immer noch  ein unschönes     Warenbild    auftritt.

      Es hat sich nun überraschenderweise gezeigt, dass  bei den genannten Feingeweben eine Schrumpffestig  keit gegen Waschen und     damit;        eine    gute Dimensions  stabilisierung erzielt werden kann, wenn diese nach  dem Verfahren gemäss dem Hauptpatent unterworfen  werden.  



  <I>Beispiel 1</I>       Baumwoll-Vollvoile    mit 16/l4 Fäden pro 1/4 franz.  Zoll und den     engl.        Garnnummern    100/2 und 100/2  in Kette und Schuss wird gesengt,     entschlichtet    und  gebleicht.

   Hierauf wird das Gewebe in Gegenwart  von Luft von 20  C der     Einwirkung    einer     66C0          Gammastrahlungsquelle    mit einer mittleren Leistung  von 6     .103    Röntgen/min während 3 Stunden aus  gesetzt, so dass eine Gesamtdosis von 1,1 - 106 Rönt  gen in das Gewebe     eingestrahlt        wird.    Das Gewebe  wird sodann mittels eines     Warmluftstroms    während  5 Minuten auf 60  C erwärmt; es ist nach dieser  Behandlung     unlöslich,    aber noch     quellbar    in einer  üblichen     Kupferoxydammoniaklösung.     



  Abschnitte des behandelten Gewebes, sowie des  unbehandelten Ausgangsgewebes wurden gemessen,  dreimal einer 30minütigen Kochwäsche mit einer  Seifenlösung unterworfen, in spannungslosem Zu  stande getrocknet und wieder gemessen, wobei fol  gende Resultate festgestellt wurden:

  Process for improving the mechanical properties of cellulose-containing textiles The main patent describes a process for improving the mechanical properties of cellulose-containing textiles with the aid of ionizing beams.

   This is characterized in that an optionally modified cellulose-containing textile material is heated to at least 30.degree. C. in the absence of a modifying agent for the cellulose during and / or after the irradiation for the purpose of crosslinking the carbon atoms of the molecular chains.



  It is known to impregnate textile fabrics made of natural or regenerated cellulose for the purpose of dimensional stabilization with a solution of a condensable synthetic resin in the presence of a catalyst, if necessary to pre-dry and to heat briefly above 100 C for the purpose of condensation of the synthetic resin. Since this method causes a rather strong reduction in fiber strength, it is mainly used for relatively coarse fabrics. On the other hand, fine woven fabrics consist of relatively high-twisted yarns that have a strong tendency to shrink, such as. B.

   Voile and marquisette, a well-known need to be able to achieve dimensional stabilization.



  It is known to stabilize voiles and marquisettes with aminoplasts, but the resin incorporation is very limited due to the reduction in fiber strength. The stabilization effect achieved brings with it both a noticeable reduction in the tendency to shrink, but the results achieved are unsatisfactory, since the remaining residual shrinkage still results in an unsightly fabric appearance.

      It has now been shown, surprisingly, that the fine fabrics mentioned have a shrinkage resistance to washing and thus; a good dimensional stabilization can be achieved if these are subjected to the process according to the main patent.



  <I> Example 1 </I> Cotton full voile with 16/14 threads per 1/4 French. Inch and the engl. Yarn numbers 100/2 and 100/2 in warp and weft are singed, desized and bleached.

   The tissue is then exposed to a 66C0 gamma radiation source with an average output of 6,103 X-rays / min for 3 hours in the presence of air at 20 C, so that a total dose of 1.1-106 X-rays is irradiated into the tissue . The fabric is then heated to 60 C for 5 minutes by means of a stream of warm air; after this treatment it is insoluble, but still swellable in a conventional copper oxide ammonia solution.



  Sections of the treated fabric, as well as the untreated starting fabric, were measured, subjected to three 30-minute hot washes with a soap solution, dried in the de-energized state and measured again, the following results being found:
