Description
<Desc/Clms Page number 1>
Des éponges synthétiques en cellulose régénérée, sur- tout lorsqu'elles sont employées pour le nettoyage du sol, ne sont pas assez durables car elles sont exposées à une forte attaque par des bactéries contre lesquelles elles ne sont pas assez résistantes. Comme d'autre part, elles présentent des avantages importants par rapport à d'autres éponges naturelles ou artificielles, on s'est efforcé de supprimer l'inconvénient ci-dessus sans détériorer les propriétés de la manière, par exemple le bon pouvoir d'absorption et la résistance.
<Desc/Clms Page number 2>
Il a été trouvé que des éponges qui sont fabriquées de manière connue en partant de viscose, peuvent être protégées par un équipement germicide contre des endommagements produits par les bactéries. Dans ce but, de telles éponges séchées par centrifugation sont plongées dans des solutions aqueuses à 1% d'acides polyacryliques d'un degré de polymérisation moyen, comprimées et ensuite traitées avec une solution aqueuse à 1% de composés ammoniques quaternaires à grosse molécule, par exemple du chlorure d'alcoyle-diméthylbenzyl-ammonium, ou monohydrate de chlorure di-isobutyl-crésoxy- éthoxy-éthyl-diméthyl-ammonium, ou monohydrate de chlorure di-isobutyl-phénoxy-éthoxy-éthyl- diméthyl-benzyl-ammonium . Il se forte alors par neutralisation des acides fortement polymères avec une base ammonique quaternaire, un film pouvant gonfler,
et pratiquement insoluble
Lorsque de telles éponges sont-exposées à l'action intense des bactéries et des champignons, on ne voit même après des semaines aucune coloration, ou seulement une faible coloration pouvant être attribuée aux endommagements.
Par le traitement ci-dessus on améliore en même cemps la. résistance à l'usure. L'amélioration de la résistance à l'usure est d'environ 30% par rapport à la normale, c'est-à-dire de 30% supérieure à la résistance des éponges qui ne sont pas imprégnées avec les substances mentionnées ci-dessus. une diminution des données physiques: résistance et porosité, ne se produit pas.
<Desc / Clms Page number 1>
Synthetic regenerated cellulose sponges, especially when used for cleaning floors, are not durable enough because they are exposed to strong attack by bacteria against which they are not resistant enough. As on the other hand, they have significant advantages over other natural or artificial sponges, efforts have been made to eliminate the above disadvantage without deteriorating the properties of the manner, for example the good power of absorption and resistance.
<Desc / Clms Page number 2>
It has been found that sponges which are made in known manner from viscose can be protected by germicidal equipment against damage produced by bacteria. For this purpose, such centrifugally dried sponges are immersed in 1% aqueous solutions of polyacrylic acids of an average degree of polymerization, compressed and then treated with a 1% aqueous solution of large molecule quaternary ammonium compounds, for example, alkyl-dimethylbenzyl-ammonium chloride, or di-isobutyl-cresoxy-ethoxy-ethyl-dimethyl-ammonium chloride monohydrate, or di-isobutyl-phenoxy-ethoxy-ethyl-dimethyl-benzyl-ammonium chloride monohydrate. It is then strong by neutralization of strongly polymeric acids with a quaternary ammonia base, a film which can swell,
and practically insoluble
When such sponges are exposed to the intense action of bacteria and fungi, even after weeks one sees no staining, or only a weak staining which can be attributed to the damage.
At the same time, the above treatment is improved. wear resistance. The improvement in wear resistance is around 30% compared to normal, that is, 30% higher than the strength of sponges which are not impregnated with the substances mentioned above . a reduction in the physical data: resistance and porosity, does not occur.
