Für besondere Zwecke, d. h. wenn es sich um Papiere von sehr geringer Porosität oder sehr dicht geschlossener Oberfläche ■ handelt, ist es notwendig, die Faserstoffe unter Auf-" wendung von bedeutender Kraft mechanisch in äußerst feine Teilstücke zu zerlegen.

H. when it comes to papers of very low porosity or very tightly closed surface, it is necessary to Use of considerable force to mechanically break it up into extremely fine pieces. However, the different types of pulp are retained still their fibrous structure in such a way that one can even get out of the ruins of the

When processing a fiber mass that is sometimes very finely ground, there is always a fiber felt that is considerable. 15 has irregularities both in its structure and in relation to the nature of its surface. In order to change these two properties, i.e. to create a dense, similar structure and one possible :

Such papers, e.g. B. Art paper, chrome paper, are so either wood containing or weighted.
Die Erfindung ersetzt diese unter Umständen durchaus unerwünschten Stoffe durch strukturlose Zellulose, die auf beliebige Weise hergestellt werden kann. Die Art der Herstellung dieser wohlbekannten Substanz, die in der Literatur als Hydro- bzw. Oxyzellulose oder auch unter anderen Bezeichnungen angesprochen wird/ist für das Verfahren übrigens gleichgültig. Es kommt lediglich darauf an, die betreffenden Faserstoffe durch chemische Behandlung in eine leicht und vollkommen zu Pulver zerreibliche Substanz zu \rerwandeln, was sich z. B. durch Einwirkung ganz verdünnter Säuren und Erwärmen leicht, sicher und mit sehr geringen Kosten ausfüh- · ren läßt. In der Papierfabrikation ist diese brüchige Form der Zellulose allgemein bekannt und wegen ihrer die Festigkeitseigenschaften des Papiers bedeutend vermindern- den Eigenschaft derart gefürchtet, daß man von jeher bestrebt ist, ihre Bildung mit allen Mitteln ängstlich zu verhüten. Die Neuheit der Erfindung beruht demgegenüber auf der Erkenntnis, daß diese Substanz unter Umständen sogar sehr nützliche Verwendung finden kann. The invention replaces these possibly quite undesirable substances with structureless cellulose that can be made in any way. The way of manufacture this well-known substance, known in the literature as hydro- or oxycellulose or is addressed under other terms for the procedure incidentally indifferent. It just depends on the fibers in question chemical treatment into a substance easily and completely friable as a powder convert what z. B. by the action of very dilute acids and warming easily, can be carried out safely and at very low cost. This is the case in paper production The brittle form of cellulose is generally known and, because of it, significantly reduces the strength properties of the paper. the property so feared that one has always endeavored to develop it with everyone Means to prevent fearful. The novelty of the invention is based on the other hand Realization that this substance can even find very useful uses under certain circumstances.
Aus dieser Substanz allein Papier zu machen, ist nicht möglich; die strukturlose Zellulose kann vielmehr nur als Zusatz zu anderen Faserstoffen, die dann um so weniger durch Mahlung verkürzt zu werden brauchen oder als Deckschicht1 auf der Oberfläche einer Papierbahn, gewissermaßen als vegetabilischer Füllstoff, für sich allein oder neben anderen Füllstoffen angewendet werden. Im ersteren Fall läßt sich auf diese Weise ein poren-' freies, unbeschwertes, daher spezifisch leichtes, holzfreies Papier von dicht geschlossener, vorzüglich bedruckbarer Oberfläche herstellen. Die strukturlose Zellulose kann sowohl in feuchter als auch in trockener Form zur Anwendung gebracht werden.It is not possible to make paper out of this substance alone; The structureless cellulose can only be used as an additive to other fibrous materials, which then need to be shortened all the less by grinding, or as a cover layer 1 on the surface of a paper web, as it were as a vegetable filler, on its own or in addition to other fillers. In the first case, a pore-free, carefree, therefore specifically light, wood-free paper with a tightly closed, excellently printable surface can be produced in this way. The structureless cellulose can be used in both moist and dry form.
