Description
Foreliggende oppfinnelse vedrører en masse som harThe present invention relates to a mass which has
lav bruddstyrke og utmerkede hydrofile egenskaper fremstilt ved inkorporering av en hydrofil bindingsfjerner av den kvartære amintypen. low breaking strength and excellent hydrophilic properties produced by the incorporation of a hydrophilic debonder of the quaternary amine type.
I de senere år har det vært foretatt stadige forsøkIn recent years, constant attempts have been made
på å forbedre de spesifikke egenskaper til cellulosemasse-avledende produkter under anvendelse av en rekke forskjellige bindingsfjernende midler. Disse bindingsfjernende midler inneholder temmelig ofte en kvartær aminkomponent på grunn av den store grad'av uavhengighet hos denne del for cellulose. Eksempler på kvartære amin-bindingsfjernere finnes i US-patenter nr. 3.554.863, 3.554.862. 3.395.708 og Reissue 26 939. Ytterligere eksempler på slike bindingsfjernere finnes i US-patent nr. 3.617.439, kanadisk patent nr. 1.020.935, britiske patenter nr. 1.282.593 og 1.180.801, samt i US-patenter nr. 3.556.931, 3.510.246 og 3.356.526. on improving the specific properties of cellulosic pulp-derivative products using a variety of different debonding agents. These debonding agents quite often contain a quaternary amine component due to the high degree of independence of this part for cellulose. Examples of quaternary amine debonders are found in US Patent Nos. 3,554,863, 3,554,862. 3,395,708 and Reissue 26,939. Additional examples of such debonders are found in US Patent No. 3,617,439, Canadian Patent No. 1,020,935, British Patent Nos. 1,282,593 and 1,180,801, as well as in US Patent No. 3,556,931, 3,510,246 and 3,356,526.
Inntil temmelig nylig har det vært aksiomatisk i masse-og papirindustrien at bindingsfjerningsfunksjonen var omvendt relatert med hydrofiliteten, dvs. økningen i bindingsfjernings-effektivitet representert ved redusert bruddstyrke ville resul-tere i redusert vannabsorpsjon. US-patent nr. 4.144.122 beskriver en kvartær aminforbindelse inneholdende gjentagende etylenoksydenheter ved to av de kvartære stillinger. Disse etylenoksydenhetene er festet t.il ammoniumionet med propylen-bindinger i hvert tilfelle og er også kjennetegnet ved en eterbinding til en alifatisk kjede i begge stillinger. Until fairly recently, it has been axiomatic in the pulp and paper industry that debonding function was inversely related to hydrophilicity, i.e. the increase in debonding efficiency represented by reduced breaking strength would result in reduced water absorption. US Patent No. 4,144,122 describes a quaternary amine compound containing repeating ethylene oxide units at two of the quaternary positions. These ethylene oxide units are attached to the ammonium ion with propylene bonds in each case and are also characterized by an ether bond to an aliphatic chain in both positions.
Ifølge US-patent nr. 4.144.122 oppnås bindingsfjerning, mens den hydrofile karakter til massen behandlet for bindingsfjerning forbedres sammenlignet med konvensjonelle masser behandlet på en slik måte. According to US Patent No. 4,144,122, bond removal is achieved, while the hydrophilic character of the pulp treated for bond removal is improved compared to conventional pulps treated in such a manner.
Ifølge foreliggende oppfinnelse er det identifisertAccording to the present invention, it is identified
en annen klasse av slike bindingsfjerningsforbindelser hvilke gir masse som endog er mer hydrofil enn massen fremstilt ifølge US-patent 4.144.122. another class of such bond-removal compounds which provide pulp that is even more hydrophilic than the pulp prepared according to US patent 4,144,122.
Ifølge foreliggende oppfinnelse tilveiebringes en hydrofil bindingsfjerner med den generelle formel: According to the present invention, a hydrophilic bond remover is provided with the general formula:
hvor:where:
= metyl, etyl, propyl, hydrogen eller hydroksyetyl,= methyl, ethyl, propyl, hydrogen or hydroxyethyl,
R2= metyl, etyl, propyl eller [etylenoksyd] hvorR2= methyl, ethyl, propyl or [ethylene oxide] where
n = 1 til 50, R^ = en alifatisk kjede med minst 4 karbonatomer, n = 1 to 50, R^ = an aliphatic chain of at least 4 carbon atoms,
R^= [etylenoksyd] n eller [propylenoksyd]nhvorR^= [ethylene oxide] n or [propylene oxide] where
n = 1 til 50 , ogn = 1 to 50 , and
X = Cl, I, Br, SO~, PO~, CH3C02.X = Cl, I, Br, SO~, PO~, CH 3 CO 2 .
Forbindelser med denne generelle formel viser faktisk forøket kapasitet med hensyn til produksjon av hydrofil masse sammenlignet med forbindelsene som er beskrevet i US-patent nr. 4.144.122. Et hvilket som helst av de valgte kjemikalier som er definert med den ovenfor angitte generelle formel kan innføres i massen eller massearket ved en rekke forskjellige steder under formingsoperasjonene av det kommersielle masse-ark. Pa grunn av massens, hydrofile egenskaper etter behandling med bindingsfjerneren, varierer anvendelsen av produkter produsert fra denne masse fra fluff benyttet i konvensjonelle absorberende materialer slik som sanitetsbind og bleier til absorberende arkmaterialer slik som papirhåndklær. Med hensyn til bleier skal det påpekes at en rekke absorpsjonsforsøk indikerer en vesentligøkning i absorpsjonen av urin sammenlignet med mer konvensjonelle bindingsfjernere og derfor har produktene ifølge foreliggende oppfinnelse en spesiell nytte-virkning i bleieprodukter. (De benyttede betegnelser bleier og bleieprodukter skal her spesielt omfatte alle inkontinens-puter og -produkter enten de er spesielt konstruert for barn eller voksne eller om de er i arkform slik som for bruk hos barn eller voksne med inkontinensproblemer i et hospital eller barnehjem.) Compounds of this general formula actually show increased capacity with respect to the production of hydrophilic mass compared to the compounds described in US Patent No. 4,144,122. Any of the selected chemicals defined by the above general formula may be introduced into the pulp or pulp sheet at a number of different locations during the forming operations of the commercial pulp sheet. Due to the hydrophilic properties of the pulp after treatment with the bond remover, the application of products produced from this pulp varies from fluff used in conventional absorbent materials such as sanitary napkins and diapers to absorbent sheet materials such as paper towels. With regard to diapers, it should be pointed out that a number of absorption tests indicate a significant increase in the absorption of urine compared to more conventional bond removers and therefore the products according to the present invention have a special beneficial effect in diaper products. (The terms diapers and diaper products used shall here in particular include all incontinence pads and products, whether they are specially designed for children or adults or whether they are in sheet form such as for use by children or adults with incontinence problems in a hospital or orphanage.)
Kvartære amraoniumforbindelser ifølge oppfinnelsenQuaternary amraonium compounds according to the invention
bør tilsettes til den våte cellulosemassen etter delignifi-sering eller bleking, enten før eller under dannelsen til ark eller kontinuerlige baner i cellulosemaskinen eller en papirmaskin. Forbindelsene er fortrinnsvis i en vandig bærer i en konsentrasjon i området fra ca. 1 til ca. 15 vekt-% av bindingsfjerneren. Disse behandlingsoppløsninger kan også inneholde konvensjonelle viskositetsreduserende additiver should be added to the wet pulp after delignification or bleaching, either before or during formation into sheets or continuous webs in the pulp machine or a paper machine. The compounds are preferably in an aqueous carrier in a concentration in the range from approx. 1 to approx. 15% by weight of the bond remover. These treatment solutions may also contain conventional viscosity-reducing additives
slik som etanol, propanol, monoetyleter eller dietylenglykol, og andre additiver som tradisjonelt er forbundet med prosess-er for tilsetning av bindingsfjernere. Mengden av den nye bindingsfjerneren basert på tørrvekten av cellulosen, varierer fra ca. 0,1 til ca. 5,0% og fortrinnsvis mellom ca. 0,2 og such as ethanol, propanol, monoethyl ether or diethylene glycol, and other additives which are traditionally associated with processes for the addition of bond removers. The amount of the new bond remover based on the dry weight of the cellulose varies from approx. 0.1 to approx. 5.0% and preferably between approx. 0.2 and

Behandlingsoppløsningen kan påføres ved blanding med en masseoppslemming. Den kan også påføres ved sprøyting eller dypping, ved hjelp av såkalte kyssvalser eller ved hjelp av annen egnet teknikk. Etter påføring kan den behandlede cellulosemasse eller papir tørkes på vanlig måte. Den behandlede cellulosen kan omdannes til cellulose-fluff som nevnt ovenfor, for anvendelse i forskjellige hygieniske produkter. På alle andre måter er papir- og massebehandling som er forbundet med håndtering av masse inneholdende disse forbindelser i det vesentlige konvensjonell. The treatment solution can be applied by mixing with a pulp slurry. It can also be applied by spraying or dipping, using so-called kissing rollers or using other suitable techniques. After application, the treated cellulose pulp or paper can be dried in the usual way. The treated cellulose can be converted into cellulose fluff as mentioned above, for use in various hygienic products. In all other respects, paper and pulp processing associated with handling pulp containing these compounds is essentially conventional.

Et eksempel på bindingsfjernere ifølge oppfinnelsen angis i det nedenstående. Eksemplet sammenligner bindings-fjerningsévnen målt gjennom sprengning ifølge Tappi standard metode T40 3 OS-76 og bruddstyrke ifølge Tappi standard metode T494 OS-70. Vannabsorpsjon bestemmes ved hjelp av følgende metode. Prøvestykker oppnås fra bindingsfjerner-behandlede håndark ved skjæring av tre vilkårlige strimler riied størrelse 25 mm X 75 mm fra hvert ark. Man finner at fem ark er tilstrekkelig for hver testbetingelse. Hver strimmel merkes ved 0,5 cm intervaller i en lengde av 3,5 cm med utgangspunkt fra kanten av 25 mm enden. An example of bond removers according to the invention is given below. The example compares the debonding ability measured by blasting according to Tappi standard method T40 3 OS-76 and breaking strength according to Tappi standard method T494 OS-70. Water absorption is determined using the following method. Specimens are obtained from bond remover-treated hand sheets by cutting three random strips of size 25 mm X 75 mm from each sheet. It is found that five sheets are sufficient for each test condition. Each strip is marked at 0.5 cm intervals for a length of 3.5 cm starting from the edge of the 25 mm end.
Avionisert vann (overflatespenning = 72 dyn/cm) an-bringes i en to-liters glassflaske. Teststrimmeleri/festes i flasken like over og perpendikulært på væskeoverflaten. Væskenivået justeres deretter inntil væskeoverflaten akkurat kommer i kontakt med strimmelen. Arket absorberer deretter væsken som stiger opp i strimmelen. En lyskilde anbragt bak flasken hjelper observasjonen av væskens stigning. Når væsken kommer i kontakt med den første 0,5 cm linjen, startes en tidtageranordning. Hver gang væsken berører den neste høyere 0,5 cm linjen noteres tiden. Dette resulterer i 90 målinger for hver testbetingelse (3 strimler/ark x 6 målinger/strimmel X 5 ark/testbetingelse). Deionized water (surface tension = 72 dyne/cm) is placed in a two-litre glass bottle. Test strips are attached to the bottle just above and perpendicular to the liquid surface. The liquid level is then adjusted until the liquid surface just contacts the strip. The sheet then absorbs the liquid that rises in the strip. A light source placed behind the bottle helps the observation of the rise of the liquid. When the liquid contacts the first 0.5 cm line, a timer device is started. Each time the liquid touches the next higher 0.5 cm line, the time is recorded. This results in 90 measurements for each test condition (3 strips/sheet x 6 measurements/strip X 5 sheets/test condition).
Hastigheten bestemmes ved å tilpasse dataene til en regresjon i tilbakelagt høyde opp strimmelen mot kvadratroten av den tid som trenges til dette. Kvadratroten skriver seg fra anvendelsen av Lucas-Washburn-ligningen. Tilpasningene er utmerket med r > 0,98 i alle tilfeller som ble vurdert. Dette resulterer i hastigheter beregnet til bedre enn<+>4%. Alle oppnådde data korrigeres for tetthet. The speed is determined by fitting the data to a regression in the height traveled up the strip against the square root of the time required for this. The square root is written from the application of the Lucas-Washburn equation. The fits are excellent with r > 0.98 in all cases considered. This results in speeds calculated to be better than<+>4%. All data obtained are corrected for density.
For alle beskrevne forsøk ble det'fremstilt hånd-For all described experiments, hand-made
ark med basisvekt 9,8 g/1000 cm 2. Det ble fremstilt tre forbindelser ifølge oppfinnelsen som bindingsfjernere og med følgende formler: sheets with a basis weight of 9.8 g/1000 cm 2. Three compounds according to the invention were prepared as bond removers and with the following formulas:
Disse forbindelser ble testet mot de kommersielt tilgjengelige bindingsfjernerne "QUAKER 2006" og "ARQUAD 2HT-75", samt "BEROCELL 579, 582 og 584" fremstilt ifølge US-patent nr. 4.144.122. Strukturen for "BEROCELL"-forbindelsene er ikke spesifikt indentifisert annet enn ved patentangivelse; "ARQUAD"-forbindelsen er et kvartært amin med en metylgruppe ved R^og R2og mettede C^g-grupper ved R3og R4. "QUAKER 2006"-forbindelsen er ikke spesifikt angitt av produsenten, men den antas å ha en femleddet ring-struktur inneholdende to nitrogenatomer med ett nitrogenatom dobbeltbundet til et av karbonatomene i ringstrukturen, idet det andre nitrogenatomet har to substituenter bundet dertil These compounds were tested against the commercially available bond removers "QUAKER 2006" and "ARQUAD 2HT-75", as well as "BEROCELL 579, 582 and 584" manufactured according to US Patent No. 4,144,122. The structure of the "BEROCELL" compounds is not specifically identified other than by patent specification; The "ARQUAD" compound is a quaternary amine with a methyl group at R₂ and R₂ and saturated C₁₂ groups at R₃ and R₄. The "QUAKER 2006" compound is not specifically stated by the manufacturer, but it is believed to have a five-membered ring structure containing two nitrogen atoms with one nitrogen atom doubly bonded to one of the carbon atoms in the ring structure, the other nitrogen atom having two substituents attached to it
i tillegg til bindingen som er forbundet med ringstrukturen. in addition to the bond associated with the ring structure.
Ved sammenligning ifølge den ovenfor beskrevneBy comparison according to the one described above
test, ble følgende verdier bestemt: test, the following values were determined:
Mens tilstrekkelig bruddstyrkereduksjon oppnås med bindingsfjernerne ifølge oppfinnelsen, fremgår det fra de ovenfor angitte data at vesentlig forbedret vannabsorpsjon tilveiebringes med de samme forbindelsene i sammenligning med f.eks. "BEROCELL"-forbindelser som angivelig gir forøket hydrofilisitet for bindingsfjernerne beskrevet i US-patent nr. 4.144.122. Disse verdier er riktige for forskjellige nivåer av bindingsfjernere. Hva som er enda mer viktig i visse tilfeller ved lavere tilsetningsnivåer for bindingsfjernere ifølge oppfinnelsen, er at hydrofilisiteten til massen som er behandlet med bindingsfjerner faktisk er større enn den til den ubehandlede massen. While sufficient breaking strength reduction is achieved with the bond removers according to the invention, it appears from the above data that significantly improved water absorption is provided with the same compounds in comparison with e.g. "BEROCELL" compounds which allegedly provide increased hydrophilicity for the bond removers described in US Patent No. 4,144,122. These values are correct for different levels of bond removers. What is even more important in certain cases at lower addition levels for bond removers according to the invention is that the hydrophilicity of the pulp treated with bond removers is actually greater than that of the untreated pulp.
Den ovenfor angitte tabell illustrerer også at dataene, selv om de forandres noe ettersom massekilden forandres, har gyldighet i det samme generelle størrelsesområde. The above table also illustrates that the data, although they change somewhat as the mass source changes, are valid in the same general size range.
Når forbindelsene ifølge oppfinnelsen ble testet med henblikk på urinabsorpsjon, basert på en syntetisk urin inneholdende følgende forbindelser: var de oppnådde verdier vesentlig større enn de for sammen-lignbare kommersielt tilgjengelige bindingsfjernere slik det fremgår fra nedenstående tabell: When the compounds according to the invention were tested for urinary absorption, based on a synthetic urine containing the following compounds: the values obtained were significantly greater than those for comparable commercially available bond removers, as can be seen from the table below:
Som det fremgår av den ovenfor angitte tabell, oppnås vesentlige nyttevirkninger fra anvendelsen av foreliggende bindingsfjerner når sluttproduktet er beregnet på As can be seen from the above table, significant beneficial effects are achieved from the use of the present bond remover when the end product is intended for
å være et fluff-materiale som senere anvendes i bleier eller produkter av lignende type. to be a fluff material that is later used in diapers or products of a similar type.
Som nevnt ovenfor kan økningen i hydrofilisitet natur-ligvis ha vesentlige ytterligere nyttevirkninger med hensyn til fluff i dens konvensjonelle anvendelser slik som f.eks. As mentioned above, the increase in hydrophilicity can naturally have significant additional beneficial effects with respect to fluff in its conventional applications such as e.g.
i sanitetsbind eller andre hygieniske produkter. in sanitary napkins or other hygienic products.
