Definitions

  • the present invention relates to the use of arabinoxylans as an additive in papermaking.
  • the mechanical properties of paper are influenced by a number of different parameters, both chemical and physical.
  • Several theories for explaining the tear strength properties of paper have been proposed, most of which emphasize the particular relevance of fiber-to-fiber bonding.
  • xylans from the raw material wood and its secondary product pulp is discussed. Specifically, the use of softwood acetyl-4-O-methyglucuronoxylan and softwood arabino-4-O-methylglucuronoxylan is cited.
  • the examples of the use of xylans call the lenzing xylan. This product is obtained by alkaline extraction of beech wood pulp in the viscose process and has only low degrees of polymerization of about 35.
  • various xylans have been investigated for their properties for fiber properties or as a paper additive. However, the work mentioned shows that an improvement in the breaking length is accompanied by a decrease in other strength properties or unacceptable deterioration of the optical properties.
  • An object of the invention is therefore the use of arabinoxylans as an additive in papermaking.
  • Suitable arabinoxylans are polysaccharides which are found, for example, in various annual plants and agricultural residues such as e.g. Oat husks, straw or corn is included.
  • the arabinoxylans can be prepared by a variety of extraction techniques, e.g. with water, steam or solvents using a variety of auxiliary chemicals and by enzymatic isolation and purification steps.
  • alkaline extracted arabinoxylans and especially arabinoxylans from oat hulls are used, e.g.
  • the peculiarity of the arabinoxylans from oat husks in comparison to the xylans from hardwood and softwood is that they have a comparatively high number of arabinose substituents but not the 4-0-methylglucuronic acids occurring in deciduous and coniferous xylans. Compared to xylans from pulps such as Lenzing xylan, the arabinoxylans have a much higher chain length.
  • arabinoxylans are understood to mean those xylans which have 5 to 20% (w / w based on the total sample), preferably 7 to 15%, particularly preferably 8 to 13%, arabinose substituents on their main chain, and less than 5 %, preferably less than 2%, more preferably less than 1% carry 4-O-methylglucuronic acid substituents (chromatographic determination of sugar after acid hydrolysis).
  • Arabinoxylans obtained by extraction of oat hulls with aqueous alkaline solution to give an alkaline extract and subsequent precipitation of the alkaline extract in a precipitation bath of water and a water-miscible organic liquid A, whereby the alkaline extract is not neutralized prior to precipitation, are particularly preferred.
  • Such arabinoxylans usually have chain lengths of at least 100 after a possible bleaching stage. In most cases, the chain lengths of these arabinoxylans are in the range 120 to 240.
  • Another object of the invention is a process for producing a pulp comprising contacting a concentrated solution or suspension of a arabinoxylans with pulp or a pulp system containing pulp.
  • the arabinoxylan solution or suspension is added to the fiber suspension prior to foliar formation.
  • the action of the arabinoxylan also takes place in combination with other paper chemicals which are introduced into the pulp before, after or together with the arabinoxylan.
  • the use of arabinoxylan for the various products of the paper industry is advantageous.
  • paper chemicals include, for example, wet strength agents, fillers, retention aids, fixatives, defoamers, deaerators, sizing agents, optical brighteners, and colorants.
  • a homogeneous solution or suspension of arabinoxylans can be achieved, for example, by strong mechanical stress such as stirring, by the action of temperature or by means of chemicals, preferably basic chemicals such as alkali metal or alkaline earth metal hydroxides, preferably NaOH.
  • concentration of the arabinoxylan solution or suspension can be varied within a wide range of 0.1% to 40% (w / w). Preferably, the range is from 0.1 to 25% (w / w), more preferably the range from 0.5% to 10% (w / w).
  • the arabinoxylan solution or suspension may then be incubated with the pulp and the desired paper aides and high consistency additives (solids content) of up to 20% before the pulp enters the headbox of the paper machine. Then you can go through Squeezing off the supernatant solution may use unadsorbed chemicals for the next batch.
  • the pulp in the headbox i. immediately before entering the papermaking machine with the additives and the arabinoxylan solution or suspension in any order.
  • the addition of arabinoxylans in the headbox usually achieves better results than the previous incubation with the pulp.
  • arabinoxylan solution or suspension is added to the pulp suspension prior to milling the pulp fibers.
  • the optimum amount used depends on which other paper auxiliaries are used in the mass, so that the amount used of the arabinoxylans based on pulp in a wide range of 0.1% up to 40% (w / w) are varied. Preferably, however, amounts of from 0.5 to 10% of arabinoxylan are used. In most cases, the use of paper additives already at lower Arabinoxylankonzentrationen the optimum increase in strength is achieved.
  • compositions of xylans are given as% w / w based on the total sample, obtained by chromatographic determination of sugar after acid hydrolysis.
  • a 4-0-methylglucuronoxylan from birch wood (no arabinose side chains, 8.8% molar ratio of 4-O-methylglucuronic acid based on xylose units, determined by 1 H-NMR, DP ca. 95) was used as a 5% solution in water dissolved under heating. 20 g of softwood sulfite pulp were suspended in water and mixed with the xylan solution. For tests with higher amounts of xylan solution, correspondingly smaller amounts of water were used to suspend the pulp. After addition of the xylan suspensions, the pulp consistency was 7.1% in each case. The experimental batches were each incubated for 2 h at 50 ° C. After incubation, the pulp was sucked through a suction filter.
  • the Lenzing xylan from beech wood pulp (no arabinose side chains, about 1% 4-O-methylglucuronic acid, DP about 35) was dissolved as a 5% solution in water with heating. 20 g of softwood sulfite pulp were suspended in water and mixed with the xylan solution. For tests with higher amounts of xylan solution, correspondingly smaller amounts of water were used to suspend the pulp. After addition of the xylan suspensions, the pulp consistency was 7.1% in each case. The experimental batches were each incubated for 2 h at 50 ° C. After incubation, the pulp was sucked through a suction filter.
  • the tear length can be improved by the addition of arabinoxylan from oat husks compared to the reference experiment by more than 1000 m. In this addition mode, increases in strength can be achieved even at lower levels of arabinoxylan use.
  • the dosage of the paper additive was consistent with a charge density of 0.013 meq / g of pulp in all experiments carried out. Subsequently, the metered addition of the Arabinoxylantheen was made. After 5 minutes, the portioning and the formation of the test sheets. All experiments were carried out at room temperature. The testing of the strengths was carried out according to ISO 974 (DIN EN 21974).
  • the tear length can be significantly increased again by the addition of arabinoxylan compared to the reference experiment. It is clear from the reference that the strengths are generally at a higher level due to the use of the paper additive. However, a synergistic effect becomes apparent in the interaction with the paper additive for the action of the arabinoxylan. The increases in the breaking length are now even up to about 1800 m. The higher increases in strength are effective even at significantly lower Arabinoxylan transitmengen than in the trials without paper additive.
  • the specific volume of the pulps is designated by the BuIk, which is plotted in FIG. 2 against the Tensile Tensile Strength (Influence of Arabinoxylan from Oat Spelts (9.38% on Pulp) on the Bulk Tensile Plot of Beech Sulfite Pulp) , It becomes clear that the curve for the different points of the freewheeling curve is shifted to higher BuIk values. To produce a product with the desired strengths, a higher sheet volume can be generated by adding the arabinoxylan. The increased BuIk leads to an increase in the light scattering coefficient and thus to better optical properties.
