Description

Verfahren zur Randverstärkung von in Schwammtüchern aus regenerierter Zellulose angebrachten Löchern Die Erfindung betrifft ein Verfahren zur Randverstärkung von in Schwammtüchern aus regenerierter Zellulose angebrachten Löchern. Process for the edge reinforcement of regenerated in sponge cloths Cellulose-Drilled Holes The invention relates to a method for edge reinforcement of holes made in sponge cloths made from regenerated cellulose.

Ein Schwammtuch besteht aus regenerierter Zellulose und darin zur Erhöhung der Zugfestigkeit eingemengten Fasern und ist mit Hohlräumen oder Poren versehen, die man durch Auslaugen von in die Viskose eingemischten löslichen Salzkristallen, z. B. A sponge cloth consists of regenerated cellulose and in it for Increasing the tensile strength of constricted fibers and is with voids or pores provided by leaching soluble salt crystals mixed into the viscose, z. B.

Glaubersalz, erzeugt. Schwammtücher mit absorbierenden Eigenschaften werden infolge ihres guten Aufsaugevermögens unter anderem im Haushalt als Spül--oder Putzlappen verwendet. Es ist erwünscht, sie für diesen Zweck mit einer Aufhängevorrichtung, beispielsweise mit einem Loch, zu versehen. Wegen der verhältnismäßig geringen Einreißfestigkeit der Schwammtuchzellulose besteht die Gefahr, daß das Schwammtuch an den Rändern derartiger Aufhängelöcher, insbesondere wenn als Aufhängeorgan Teile mit Kanten, wie beispielsweise Haken, verwendet werden, einreißt. Aus diesem Grunde ist eine Randverstärkung derartiger Aufhängelöcher in Schwammtüchern erwünscht.Glauber's salt, produced. Sponge cloths with absorbent properties are used in the household as a dishwashing or washing machine due to their good absorption capacity Cleaning rags used. It is desirable to attach them to a hanging device for this purpose, for example with a hole. Because of the relatively low tear resistance the sponge cloth cellulose there is a risk that the sponge cloth at the edges such hanging holes, especially if parts with edges are used as hanging elements, such as hooks, are used. For this reason is a Edge reinforcement of such hanging holes in sponge cloths is desirable.

Es ist an sich bekannt, zur Verbesserung der allgemeinen Eigenschaften, darunter auch der Reißfestigkeit, von natürlichem bzw. Zelluloseschwammaterial diesem in bestimmtem Verhältnis ein natürliches oder künstliches elastisches Material, beispielsweise Kautschuklatex oder Polyvinylchlorid, einzumengen, was durch Tränken der Schwammaterialien mit den genannten elastischen Stoffen erfolgen kann. It is known per se to improve the general properties, including the tear resistance of natural or cellulose sponge material in a certain proportion a natural or artificial elastic material, for example rubber latex or polyvinyl chloride, which can be confined by soaking the sponge materials can be made with the elastic fabrics mentioned.

Es ist ferner bei Schaumstoffen bzw. bei aus regenerierter Zellulose hergestellten Schwammgebilden, bekannt, diese in bekannter Weise mechanisch zu bearbeiten, insbesondere sie zur Herstellung durchgehender Öffnungen zu durchbohren. It is also the case with foams or with regenerated cellulose manufactured sponge structures, known to process them mechanically in a known manner, in particular to pierce them to produce through openings.

Um die in Schwammtüchern aus regenerierter Zellulose angebrachten Löcher in der erwünschten Weise am Rand zur Erhöhung der Einreißfestigkeit zu verstärken, ist gemäß der Erfindung vorgesehen, daß ein Stapel übereinandergeschichteter Schwammtücher in an sich bekannter Weise durchbohrt und in diese Bohrung ein gelochtes Rohr eingeführt wird, welches eine Kunststofflösung enthält, die bei Hindurchtreten durch die Rohrlöcher von den die Bohrung umgebenden Randteilen der Schwammtücher aufgesaugt wird und sich anschließend allmählich unter Bildung der Kunststoffverstärkung der Lochränder verfestigt. Around those attached in sponge cloths made from regenerated cellulose To reinforce holes in the desired way at the edge to increase the tear resistance, it is provided according to the invention that a stack of superimposed sponge cloths pierced in a known manner and inserted a perforated tube into this bore which contains a plastic solution, which when passing through the pipe holes is absorbed by the edge parts of the sponge cloths surrounding the bore and then gradually to form the plastic reinforcement of the hole edges solidified.

Das Verfahren gemäß der Erfindung hat den Vorteil, daß nach der an sich bekannten Herstellung der Löcher in einfacher Weise eine Kunststoffverstärkung der Lochränder erzielt wird. Vorzugsweise wird für die gemäß der Erfindung vorgesehene Randverstär- kung ein solcher Kunststoff verwendet, daß der verstärkte Lochrand im nassen Zustand verhältnismäßig weich ist, damit die Handhabung des Tuchs beim Gebrauch nicht behindert wird und insbesondere die Lochrandverstärkung keine Kratzer auf empfindlichen Oberflächen verursachen kann. The method according to the invention has the advantage that after the on known production of the holes in a simple manner a plastic reinforcement the hole edges is achieved. Preferably it is provided for according to the invention Edge reinforcement kung uses such a plastic that the reinforced edge of the hole in the When wet, it is relatively soft, so that the handling of the cloth during use is not hindered and in particular the perforated edge reinforcement does not have any scratches sensitive surfaces.

Als Beispiele für geeignete Kunststoffe seien erwähnt: Polyvinylchlorid, Polyvinylazetat, Polyvinylbutyral sowie Akrylharze. Examples of suitable plastics are: polyvinyl chloride, Polyvinyl acetate, polyvinyl butyral, and acrylic resins.
