Hach dem Verfahren de· Hauptpatent·· (BBP ..· Anmeldung B 38.424 IV c/8 1) wird beim Blelohen von Beetfasern in lo««r Form oder in Form von Garnen, Kreuzspulen, Geweben« Gewirken und Textilwaren sohon in der ersten Stufe des Bleichvorganges ein guter Bleicheffekt erzielt, wenn man unter Versieht auf eine Vorkoohung in der ersten Stufe mit Peroxyd und in der zweiten Stufe mit Hatriumchlorit oderChlordioxyd bleicht.According to the procedure de · main patent ·· (BBP .. · registration B 38.424 IV c / 8 1) when bleaching bed fibers in lo «« r Form or in the form of yarns, cheeses, woven fabrics, knitted fabrics and textile goods at the first stage of the bleaching process a good bleaching effect is achieved if one underlays on a pre-charring in the first stage with peroxide and in the second stage with sodium chlorite or chlorine dioxide.

In Weiterbildung de· Verfahrene d«4 Hauptpatentee wurde nun über· raschenderweiee gefunden, daß man mindestens den gleiohen, in manchen Fällen sogar einen noch besseren Bleioheffekt bei dem Verfahren des Hauptpatentes erzielt, wenn dl« Peroxydbleiohe nicht,wie allgemein Üblich, bei erhöhter Temperatur eondern bei Normaltemperatur ohne zusätzlich· Erwärmung durchgeführt wird· Entgegen den Erwartungen genügt auoh beim Arbeiten nach der vorliegenden Erfindung bei normaler Temperatur «ine Behänd limgwlt von 3-5 Stünden, ohne daß der Aufwand an Bleichohemikalien höher wäre als bei der heißen Peroxyd-Bleiohe.In further training of the · process d «4 main patents has now been over · surprisingly found that at least the same in In some cases an even better lead effect is achieved in the process of the main patent if the lead is peroxide not, as is generally the case, at elevated temperatures, but rather at Normal temperature is carried out without additional heating. Contrary to expectations, even when working according to the present invention at normal temperature, a handling limit is sufficient 3-5 hours without the need for bleach chemicals would be higher than with the hot lead peroxide.

Bas Verfahren gemäß Erfindung wird an Band des nachstehenden Beispieles erläutert!The method according to the invention is based on the following Example explained!

Grobes Leinengewebe wird ohne Vorkochen mit einer BlelohlOsung imprägniert, die folgend· Zueammaneetsung aufweist (dl· Angaben. beziehen sich auf den Gehalt von 1 Liter Bleiohlösung)iCoarse linen fabric is made with a Blelohl solution without pre-cooking impregnated, which has the following · Zueammaneetsung (dl · information. refer to the content of 1 liter of lead solution) i
