Werkwijze voor het vervaardigen van papier en papier vervaardigd volgens de werkwijze.Method for manufacturing paper and paper produced according to the method.
De uitvinding heeft betrekking op een werkwijze voor het vervaardigen van papier onder gebruikmaking van een papierma-5 chine, waarbij een suspensie van water en papiervezels op een zeef wordt gebracht om vervolgens ontwaterd en gedroogd te worden.The invention relates to a method for manufacturing paper using a paper machine, wherein a suspension of water and paper fibers is applied to a screen to be subsequently dewatered and dried.
Een op deze wijze vervaardigd papier heeft een betrekkelijk geringe "natsterkte" dat wil zeggen dat het onder vochti-10 ge omstandigheden slechts een geringe sterkte bezit. Het is daardoor minder geschikt voor het er uit vervaardigen van bijvoorbeeld schoonmaakdoekjes die in een vochtighoudende verpakking worden opgenomen.A paper produced in this way has a relatively low "wet strength", that is, it has only a low strength under humid conditions. It is therefore less suitable for manufacturing, for example, cleaning wipes that are included in a moisturizing package.
De uitvinding beoogt nu dit bezwaar op te heffen en een 15 papier te verschaffen met een verbeterde "natsterkte".The invention now has for its object to eliminate this drawback and to provide a paper with an improved "wet strength".
Volgens de uitvinding wordt er daartoe in voorzien, dat aan de suspensie van papiervezels vezels uit een kunststof-materiaal worden toegevoegd.According to the invention it is provided for this purpose that fibers from a plastic material are added to the paper fiber suspension.
Volgens de uitvinding kan daarbij de diameter van de 20 kunststofvezels liggen tussen 1,4 en 2,5 dtex en de lengte tussen 4 en 10 mm, terwijl de diameter in het bijzonder zal liggen tussen 1,7 en 2,2 dtex en de lengte tussen 6 en 8 mm.According to the invention, the diameter of the plastic fibers can be between 1.4 and 2.5 dtex and the length between 4 and 10 mm, while the diameter will in particular be between 1.7 and 2.2 dtex and the length between 6 and 8 mm.
De hoeveelheid kunststofvezels zal bij voorkeur liggen tussen 5 en 30 % van de totale hoeveelheid vezels.The amount of plastic fibers will preferably be between 5 and 30% of the total amount of fibers.
25 Volgens een uitwerking van de uitvinding kan daarbij gebruik worden gemaakt van kunststofvezels uit polypropeen PP en/of polyetheen PE.According to an elaboration of the invention, use can herein be made of plastic fibers from polypropylene PP and / or polyethylene PE.
In het bijzonder zal daarbij gebruik worden gemaakt van een bi-component van polypropeen PP en polyetheen PE waarbij 30 PP de kern vormt voor het leveren van sterkte aan de vezels en PE de buitenlaag vormt voor het tot stand brengen van de verbinding van de kunststofvezels onderling.Use will in particular be made here of a bi-component of polypropylene PP and polyethylene PE, wherein PP forms the core for supplying strength to the fibers and PE forms the outer layer for establishing the connection between the plastic fibers and each other. .
In het bijzonder zal de smelttemperatuur van de kunststofvezels liggen tussen 90 en 160°C.In particular, the melting temperature of the plastic fibers will be between 90 and 160 ° C.
35 De kunststofvezels kunnen vooraf, met de papiervezels worden gemengd of kunnen in de suspensie van die vezels worden geïnjecteerd voordat de suspensie op de zeef wordt gebracht.The plastic fibers can be pre-mixed with the paper fibers or can be injected into the suspension of those fibers before the suspension is applied to the screen.
Om te voorkomen dat de kunststofvezels in de suspensie 1 03233 1 .To prevent the plastic fibers in the suspension 1 03233 1.
* 2 gaan "flotteren" en samenklonteren zullen bij toepassing van de werkwijze de kunststofvezels bij voorkeur vooraf met water worden gemengd.* 2 "flotate" and caking together, using the method, the plastic fibers will preferably be premixed with water.
Daarbij zal de hoeveelheid vezels in het mengsel tussen 5 1,5 en 3 % bedragen.The amount of fibers in the mixture will be between 1.5 and 3%.
In verband met het versmelten van de kunststofvezels aan elkaar zal de temperatuur van het blad minimaal 100°C bedragen .In connection with the fusing of the plastic fibers together, the temperature of the sheet will be at least 100 ° C.
Op overigens bekende wijze kan het verkregen produkt 10 tijdens of na het drogen worden gecrêpt. Voor het verkrijgen van een produkt met optimale eigenschappen zal daarbij volgens de uitvinding het vochtgehalte van het produkt voor of direct na het crêpen maximaal 30 % bedragen.In otherwise known manner, the product obtained can be cropped during or after drying. In order to obtain a product with optimum properties, the moisture content of the product before or immediately after creping will be a maximum of 30% according to the invention.
Bij toepassing van de werkwijze volgens de uitvinding kan 15 gebruik worden gemaakt van een standaard tissue/crêpe papiermachine. Daarbij is het toepassen van een kunststof zeef, een vilt en een Yankee droogcilinder eveneens standaard. Het crêpen van het papier gebeurt doordat het aan de cilinder plakkende papier van de cilinder wordt afgeschraapt.When applying the method according to the invention, use can be made of a standard tissue / crepe paper machine. The use of a plastic screen, a felt and a Yankee drying cylinder is also standard. The creation of the paper occurs because the paper sticking to the cylinder is scraped from the cylinder.
20 Het zal duidelijk zijn, dat de uitvinding niet beperkt is tot het gebruik van de boven genoemde kunststofvezels maar dat de vezels ook een andere samenstelling kunnen hebben en dat ook verdere wijzigingen in de werkwijze en de manier van vezels binden kunnen worden aangebracht zonder buiten de 25 uitvindings-gedachte te vallen.It will be clear that the invention is not limited to the use of the above-mentioned plastic fibers, but that the fibers can also have a different composition and that further changes in the method and the manner of binding fibers can be made without departing from the 25 inventive idea.
