Description
Binde f r medizinische Zwecke, Bandagen und dergleichen
Als Binden für medizinische Zwecke, Bandagen usw. werden Mullstreifen verwendet, die auf Grund des Fadenmaterials und der Webart beim Gebrauch anschmiegsam sind und die gepresst raumsparend ver- packt werden können.
Ferner sind für gleiche Zwecke sogenannte Papierbinden bekannt, denen eine Kreppung eine gewisse Elastizität verleiht. Die Kreppung versteift jedoch gleichzeitig den Bindenstreifen, der aufgewickelt ausserdem sehr voluminösist.BeiderVerarbeitung gekreppter Papiere ist es ferner bekannt, die ge- kreppte Bahn mit geprägten Streifen oder Zierorna- menten zu versehen.
Die Erfindung bezieht sich auf eine Binde fur medizinische Zwecke, Bandagen und dergleichen. Die Erfindung besteht darin, da¯ in einer gekreppten Materialbahn mehrere Kreppfalten übengreifende Hochprägungen ausgebildet sind. Nachstehend werden Ausf hrungsbeispiele der Erfindung erörtert :
Besonders geeignet für die Ausbildung der PrÏgungen sind örtlich begrenzte dreidimensionale Hochprägungen, die iiber die fortlaufende Bahn nach Art eines Musters verteilt sind.
Als besonders vorteilhaft erweist sich die Krep- pung und nachträgliche Prägung in einer aus verfestigtem Faservlies bestehenden, als Vliesstoff bezeichneten ungewebten Materialbahn.
Das zunächst gekreppte und anschliessend ge prägte Material kann einer nachträglichen Glättung durch Walzen unterworfen werden.
Die Kreppung erfolgt nach an sich bekannten Methoden, beispielsweise zwischen Kreppwalzen, bei denen eine untere Stahlwalze mit rauher Oberfläche und eine schneller angetriebene Oberwalze vorgesehen sind. Die Kreppung kann beispielsweise 60% der Lange betragen. Die so gekreppte Bahn wird dann beispielsweise durch einen Prägekalander geleitet, dessen Unterwalze aus Stahl ein Prägemuster aus- weist. Dieses besteht aus aneinander stossenden, kup- pelförmigen Erhöhungen, die sich bei der Prägung im Walzenspalt gegenüber. einer weicheren Oberwalze kuppelförmig abformen. Der Feuchtigkeitsge- halt der Bahn kann hierbei gering sein.
Die Prägungen sind dreidimensional ausgeführt, d. h. jede örtlich begrenzte Hochprägung entspricht dieser Bedingung. Dieses hat zur Folge, dass der Rand der Hochprägungen. die bis dahin durchlaufenden Kreppfalten unterbricht. Ferner wenden die Krepp- falten im Bereich jeder Prägung in die Konturen des Prägemusters s gleichsam hereingezogen bzw. etwas genafft, was zu Folge hat, da¯ die Kreppung stabili- siert ist.
Als besonders geeignet erweist sich ein Vliesstoff, der aus verfestigten Faservliesen aus Cellulosefasern besteht, die ohne Zusätze von Klebemitteln verfestigt sind.
Derart hergestellte Binden bzw. Biandagen zeigen eine hohe Elastizität und. gleichzeitig beim Anlegen von Verbänden eine den Mullbinden entsprechende Anschmiegsamkeit beim Herstellen von Windungen, Kreuzungen und Umleitungen. Dieses ist voraussichtlich darauf zur ckzuf hren, da¯ die in ganzer Bahn gekreppte und geprägte Binde bei der Zugbeanspru- chung allseitig nachgiebig ist, die an sich starren Kreppfalten sind durch das Prägemuster überall unterbrochen. Die Prägung bergreift gleichsam die Kreppfalten, die erst nach der Auflösung der Prägung frei werden. Die Binden können ferner ohne Verlust , der Dehnbarkeit und Anschmiegsamkeit durch Walzen geglättet werden, während gekrepptes Material , die Dehnbankeit in Walzenspalt verliert.
Die für das Biodenmaterial erwünschten Eigenschaften bleiben ferner auch erhalten, wenn die gekreppte und ge prägte Binde z. B. zur Herstellung von Verbandma- terial aufgerollt oder als Verbandpäckchen gepresst wird, so dass etwa die gleiche raumsparende Verpackung möglich ist wie bei Mullbinden. Diesen gegenüber wird jedoch eine gesteigerte Dehnbarkeit erreicht, so da¯ das Bindenmaterial auch zur Herstellung von Kompressionsbindenmaterial geeignet ist. Die Prägemuster können kuppelförmig, pyramidenförmig, als Waffelmuster oder dergleichen ausgeführt sein.
Als Bindenmaterial eignen sich alle kreppfÏhigen Stoffe, die den Anforderungen an Bindenmaterial f r medizinische Zwecke entsprechen. Dies gilt z. B. auch f r die hygienischen Anforderungen und die Sterili sierfähigkeit. Die Binden können als breite Bahn hergestellt und anschliessend zugeschnitten werden.
Bandages for medical purposes, bandages and the like
Gauze strips are used as bandages for medical purposes, bandages, etc., which, due to the thread material and the type of weave, are supple during use and which can be compressed and packed to save space.
Furthermore, so-called paper bindings are known for the same purposes, to which a creping gives a certain elasticity. At the same time, however, the creping stiffens the binding strip, which is also very voluminous when wound up. When processing creped papers, it is also known to provide the creped web with embossed strips or decorative ornaments.
The invention relates to a sanitary napkin, bandage and the like. The invention consists in that in a creped material web several embossed embossings are formed which overlap crepe folds. Exemplary embodiments of the invention are discussed below:
Locally limited three-dimensional embossing, which is distributed over the continuous path in the manner of a pattern, is particularly suitable for the formation of the embossments.
The creping and subsequent embossing in a non-woven material web made of solidified fiber fleece and referred to as non-woven material has proven to be particularly advantageous.
The initially creped and then embossed material can be subjected to subsequent smoothing by rolling.
The creping is carried out by methods known per se, for example between creping rollers, in which a lower steel roller with a rough surface and a faster driven upper roller are provided. The creping can be 60% of the length, for example. The web creped in this way is then passed, for example, through an embossing calender, the steel lower roller of which has an embossing pattern. This consists of adjoining, dome-shaped elevations, which are opposite each other when embossed in the nip. Form a dome-shaped impression using a softer top roller. The moisture content of the web can be low here.
The embossments are three-dimensional, i. H. any locally limited embossing corresponds to this condition. This has the consequence that the edge of the embossing. interrupts the crepe folds that have passed through until then. In addition, the crepe folds in the area of each embossing turn into the contours of the embossing pattern, as it were, drawn in or somewhat pinched, which has the result that the creping is stabilized.
A nonwoven fabric which consists of consolidated nonwovens made of cellulose fibers which is consolidated without the addition of adhesives has proven to be particularly suitable.
Bandages or bandages produced in this way show high elasticity and. At the same time, when bandages are being put on, they are conformable to the gauze bandages when making turns, crossings and diversions. This is presumably due to the fact that the bandage, which is creped and embossed over the entire length, is flexible on all sides when subjected to tensile stress, the crepe folds, which are rigid per se, are interrupted everywhere by the embossing pattern. The embossing takes hold of the crepe folds, which only become free after the embossing has dissolved. The bandages can also be smoothed by rollers without loss of elasticity and conformability, while creped material loses its elasticity in the roller gap.
The properties desired for the biodegradable material are also retained when the creped and embossed bandage z. B. for the production of bandage material is rolled up or pressed as a bandage pack, so that about the same space-saving packaging is possible as with gauze bandages. Compared to these, however, increased extensibility is achieved, so that the bandage material is also suitable for the production of compression bandage material. The embossing patterns can be dome-shaped, pyramidal, waffle-shaped or the like.
All crepe-capable materials that meet the requirements for bandages for medical purposes are suitable as bandage material. This applies e.g. B. also for the hygienic requirements and the sterilization ability. The bandages can be made as a wide web and then cut to size.
