Abstract

Leather processing by laser treatment comprises irradiating the leather with light, preferably intrared and/or ultraviolet light, during or after processing.

Description

Die Erfindung betrifft Verfahren zur Bearbeitung von Leder mittels Laserstrahlung.The The invention relates to methods of processing leather by means of laser radiation.

Die üblen Brenngerüche bei der Laserbearbeitung werden durch eine nur teilweise Verbrennung von tierischem Eiweiß verursacht. Die Teilverbrennung entsteht an den Schnitträndern beim Laserschneiden im energetischen Übergangsbereich.The bad smell of burning The laser processing are characterized by an only partial combustion of caused by animal protein. Partial combustion occurs at the cutting edges during laser cutting in the energetic transitional area.

Aufgabe der Erfindung ist es, den Verbrennungsgeruch bei der Bearbeitung von Leder mittels Laserstrahlung zu reduzieren.task The invention is the combustion smell during processing of leather by means of laser radiation.

Diese Aufgabe wird bei einem Verfahren zur Bearbeitung von Leder mittels Laserstrahlung dadurch gelöst, daß das Leder während oder nach der Bearbeitung mit Licht, vorzugsweise infrarotem und/oder ultraviolettem Licht, bestrahlt wird.These Task is in a method for processing leather means Solved laser radiation, that this Leather while or after processing with light, preferably infrared and / or ultraviolet light, is irradiated.

Der Versuch zeigt eine Methode zur Nachoxidation der unverbrannten Rückstände.Of the Experiment shows a method for post-oxidation of unburned residues.

Ein nach der Laserbearbeitung übel stinkendes Stück Leder wird gleichzeitig mit

  • • infrarotem und/oder
  • • ultraviolettem
Licht bestrahlt.A smelly piece of leather after laser processing becomes simultaneously with
  • • infrared and / or
  • • ultraviolet
Light irradiated.

Dabei werden folgende Effekte erzielt:

  • • Die infraroten Lichtanteile (Wärmestrahlung) dringen in das Leder ein und reichern die Brennrückstände energetisch an. Diese werden dadurch – physikalisch aktiv und diffundieren besser aus dem Leder heraus und – chemisch aktiver.
  • • Die ultravioletten Lichtanteile bewirken eine chemische Reaktion von Luft-O2 zu Ozon O3, welches als instabiles Gas in O2 und O zerfällt. Dieses molekulare O ist sehr reaktionsfreudig und gilt als sehr guter Oxidator. 3O2 → 2O3 zerfällt zu 2O2 + 2O
The following effects are achieved:
  • • The infrared light components (thermal radiation) penetrate into the leather and energetically enrich the firing residues. These become - physically active and diffuse better out of the leather and - chemically active.
  • • The ultraviolet light components cause a chemical reaction of air O2 to ozone O3, which decomposes into O2 and O as an unstable gas. This molecular O is very reactive and is considered a very good oxidizer. 3O 2 → 2O 3 decomposes to 2O 2 + 2O

Die teilverbrannten Eiweißprodukte werden durch das molekulare O nachverbrannt und dadurch geruchlos.The partially-burned protein products are burned by the molecular O and thereby odorless.
