Abstract
Description
Die vorliegende Erfindung betrifft die Verwendung von Alkalicitrat und/oder Alkaligluconat zur Reinigung von mit kalkhaltigen Anschmutzungen verschmutzte Arbeitsschutzkleidung, insbesondere von Arbeitsschutzkleidung des Baugewerbes.The present invention relates to the use of alkali citrate and / or alkali gluconate for cleaning work protective clothing soiled with calcareous soiling, in particular work protective clothing for the construction industry.
Arbeitsschutzkleidung,insbesondere die Arbeitsschutzkleidung des Baugewerbes, weist nach Gebrauch in der Regel sehr starke kalkhaltige Anschmutzungen auf, die nur durch spezielle Reinigungsverfahren wieder entfernt werden können. Häufig können die Anschmutzungen nicht vollständig entfernt werden, auch weist insbesondere weiße Arbeitsschutzkleidung schon nach wenigen Wäschen einen sogenannten Grauschleier auf.Protective work clothing, especially the protective work clothing of the construction industry, usually shows very heavy soiling that can only be removed by special cleaning processes. Frequently, the soiling cannot be completely removed, and white protective clothing in particular has a so-called gray veil after just a few washes.
Derzeit wird in gewerblichen Wäschereien Arbeitsschutzkleidung unter Einsatz von Spezialwaschmitteln gewaschen. Diese Spezialwaschmittel für Arbeitsschutzkleidung haben jedoch den Nachteil, daß sie ökologisch bedenkliche Substanzen wie Phosphate enthalten. Häufig werden die eingesetzten Spezialwaschmittel in Kombination mit Säuren wie Essigsäure, Ameisensäure oder Salzsäure verwendet. Der Einsatz der Säuren erfordert jedoch größere Vorsichtsmaßnahmen bei der Lagerung und der Handhabung, weiterhin ist der unangenehme Geruch der Säuren nachteilig. Ein ganz wesentlicher Nachteil bei Einsatz der Säuren ist die erhöhte Faserschädigung.Protective work clothing is currently being washed in commercial laundries using special detergents. However, these special detergents for protective work clothing have the disadvantage that they contain ecologically questionable substances such as phosphates. The special detergents used are often used in combination with acids such as acetic acid, formic acid or hydrochloric acid. However, the use of the acids requires greater precautionary measures during storage and handling, and the unpleasant smell of the acids is also disadvantageous. A major disadvantage when using the acids is the increased fiber damage.
Aus dem Stand der Technik sind einige Mittel zum Reinigen von Arbeitsschutzkleidung bekannt. So wird in der französischen Patentanmeldung FR-A-1602077 beispielsweise ein Wasch-, Waschhilfs- und Reinigungsmittel beschrieben, das antimikrobielle Wirkstoffe enthält, wobei das Mittel 0,2 bis 30 Gew.-% eines substituierten 2-Hydroxydiphenylethers, 99,8 bis 5 Gew.-% Tenside sowie weitere übliche Bestandteile von Wasch-, Waschhilfs- und Reinigungsmitteln enthält.Some means for cleaning protective work clothing are known from the prior art. French patent application FR-A-1602077, for example, describes a detergent, auxiliary washing agent and cleaning agent which contains antimicrobial agents, the agent comprising 0.2 to 30% by weight of a substituted 2-hydroxydiphenyl ether, 99.8 to 5 Wt .-% surfactants and other common components of washing, washing aids and cleaning agents.
In der europäischen Patentanmeldung EP-A-0 352 244 wird eine stabilisierte enzymhaltige, flüssige Reinigungsmittelzusammensetzung, die unter anderem zum Reinigen von Arbeitsbekleidung geeignet ist, beschrieben. Das dort beschriebene Mittel enthält von 1 bis 50 Gew.-% eines amphoteren Tensids. Als Enzyme werden bevorzugt Protease, Amylase oder Cellulase eingesetzt.European patent application EP-A-0 352 244 describes a stabilized, enzyme-containing, liquid detergent composition which is suitable, inter alia, for cleaning work clothing.

Um die Wirksamkeit von Alkalicitrat und/oder Alkaligluconat zur Reinigung von mit kalkhaltigen Anschmutzungen verschmutzte Arbeitsschutzkleidung, insbesondere von Arbeitsschutzkleidung des Baugewerbes, zu zeigen wurden verschmutzte Gewebe mit Natriumcitrat bzw. Natriumgluconat und verschiedenen Kombinationen daraus behandelt und die Remissionswerte bestimmt. Als Standard wurde ein verschmutzter Textilstreifen verwendet, der unbehandelt blieb.In order to demonstrate the effectiveness of alkali citrate and / or alkali gluconate for cleaning work protective clothing contaminated with lime-containing soiling, in particular work protective clothing from the construction industry, soiled fabrics were treated with sodium citrate or sodium gluconate and various combinations thereof and the remission values were determined. As a standard, a dirty textile strip was used, which remained untreated.
Es wurden 3,5 kg saubere abgezogene Füllwäsche incl. Testgewebe bei 60°C in einer Haushaltswaschmaschine (Miele W700) gewaschen. Die Testgewebe waren jeweils mit Schnellzement Ceromax(R) CX5 verschmutzt. Es wurden 200 ml einer 10%igen Lösung von Na-Citrat und/oder Natriumgluconat in dem in Tabelle 2 wiedergegebenen Verhältnis zugegeben und die Remissionswerte bestimmt. Die Ergebnisse sind in Tabelle 2 dargestellt.3.5 kg of clean peeled laundry including test fabric were washed at 60 ° C. in a household washing machine (Miele W700). The test fabrics were each soiled with Ceromax (R) CX5 quick-setting cement. 200 ml of a 10% solution of Na citrate and / or sodium gluconate were added in the ratio shown in Table 2 and the reflectance values were determined.
