A PROCESS FOR CONTROLLING THE DEPOSITION OF STICKIES FROM PAPER STOCK SUSPENSIONS

The invention relates to a process for controlling the precipitation of adhesive impurities ("stickies") from paper material suspensions in papermaking. According to the invention, the deposit of stickies is controlled by adding to the paper material suspension an effective quantity of alkoxylation products obtainable by reacting alkylene oxides with C10-22 carboxylic acid derivatives and/or C10-22 carboxylic acids containing carboxylic acid radicals with at least on OH group in position 9, 10, 13 and/or 14.

WATER-DISINTEGRATABLE FIBROUS SHEET

A fibrous sheet coated with a water-soluble binder of polyvinyl alcohol is impregnated with an aqueous solution dissolved with water-soluble carboxylate, so as to produce a water-disintegratable fibrous sheet. Salting out of the polyvinyl alcohol with the carboxylate maintains wet strength of the water-disintegratable fibrous sheet even in a wet state, which is easily disintegrated when immersed in a large amount of water after use. Furthermore, it does not suffer from deterioration in water-disintegratability and wet strength if it is left at high temperatures, and is good in water-disintegratability in cold water.

Apparatus and method for encoding binary shape signals in shape coding technique

PURPOSE: A system and a method for encoding a binary form signal are provided to arithmetic-encode a binary form signal in unit of one pixel or in unit of predetermined PxP sub-block on the basis of the quantity of generation of bits after encoding. CONSTITUTION: When binary pixel values in a binary form signal extracted from a video frame are arithmetic-encoded, binary pixel values in a corresponding binary alpha block are encoded in unit of one pixel and in unit of PxP sub-block. The number of bits after the encoding is calculated. Encoded data having smaller number of bits is selected as final output data, thereby remarkably improving encoding efficiency of the binary form signal.

Oil-containing paper produced by admixing oil-containing - microcapsules to paper pulp and pressing the paper

Oil is encapsulated in polymeric envelopes by known methods; the resulting microcapsules are uniformly distributed in a paper pulp; paper sheets or strips are produced in the normal way and then subjected to pressure to crush the microcapsules. By this method, the oil is uniformly distributed throughout the paper and staining during the production is avoided. Semi-transparent papers so produced are suitable for photographic applications, as the paper, being less hydrophobic than known oil-impregnated papers, has a good receptivity for photographic emulsions. These papers have also good ink-receptivity and resistance to oils (parchment). Suitable oils include tributyl and tricresyl phosphates, paraffin, ethyl and butyl phthalates, butyl oleate, amyl laurate, diphenyl derivatives and natural fatty oils. Suitable polymeric materials include gelatin, casein, sodium alginate, gum arabic, styrene-maleic anhydride copolymers, urea-formaldehyde resins, polyisocyanates, polyamines, epoxy resins, waxes, polystyrene, polyvinyl chloride and vinyl chloride-vinyl acetate copolymers. The microcapsules are preferably used in an amount of 20% with respect to the weight of dry paper substance.

Humate-dyed, tobacco paper - is treated with magnesium sulphate to insolubilise humate and reduce carbon mon:oxide generation on pyrolysis

When dyeing tobacco paper with a humic acid salt soln., pref. of pH 7-8, the humate is fixed by treating the paper with sufficient MgSO4 soln. to insolubilise the humate on paper and render it colour-fast. Fixing with MGSO4 soln. achieves desired brown colour intensity and reduces generation of gas phase components, e.g. CO, on smoking. CO generation is lower than that obtd. on fixing with CaCl2 or Mg(OAc)2. Pref. the MgSO4 soln. has a concn. of 1-5.5 wt.%; the humate is esp. Na humate; and acid-soluble material is pref. removed before dyeing, by treating the humate soln. at pH 5-7.

Patent FR2145617B1

Paper quality improver for papermaking and method for producing pulp sheet

The present invention provides a paper quality improver for papermaking, which is excellent in efficiency of improving bulky value, brightness, opacity and the like of pulp sheet, wherein the improving is desirable at lightening paper and increasing amount of deinked pulp, if small amount of the paper quality improver is added; and provides a pulp sheet whose bulky value, brightness, opacity and the like are improved. Further, the present invention provides a dry efficiency improver and a drying method which are able to improve easily a dry efficiency of a wet paper and water-squeezed product. That is to say, in the present invention, a compound is used as the paper quality improver for papermaking, wherein the compound is led to have not less than 4% of lyotropic degree measured by a specific method and the compound satisfies at least two of any ones selected from (i) standard improved bulky value of not less than 0.02 g/cm3, (ii) standard improved brightness of not less than 0.5 point and (iii) standard improved opacity of not less than 0.5 point. That is to say, also, in the present invention, there is obtained the pulp sheet, whereby a compound being led to have not less than 4% of lyotropic degree measured by a specific method is added internally into pulp slurry before or in papermaking step, wherein the pulp sheet satisfies at least two of any ones selected from (1) improved bulky value of not less than 0.02 g/cm3, (2) improved brightness of not less than 0.5 point and (3) improved opacity of not less than 0.5 point. Further, the present invention is use, as a dry efficiency improver, of a compound being led to have not less than 4% of lyotropic degree measured by a specific method and satisfying at least one selected from (i) standard improved bulky value of not less than 0.02 g/cm3, (ii) standard improved brightness of not less than 0.5 point and (iii) standard improved opacity of not less than 0.5 point.

MISCIBLE COMPOSITION WITH WATER, COMPOUND, EMULSION OF WATER - EMOLEO, AND PROCESSES FOR PREPARING THE COMPOSITION, FOR ITS DILUTION, FOR FLOCULATION OF A WATER MUD AND FOR THE MANUFACTURE OF PAPER, AS WELL AS AN APPLIANCE TO MAKE SUCH DILUIO CAIS

Papermaking method using one or more quaternized dialkanolamine fatty acid ester compounds to control opacity and paper product made thereby

A method for making an opacity relevant grade paper or paperboard product, such as a communication type paper used for printing and writing applications, utilizes an effective amount of quaternized alkanolamine fatty acid ester compounds as an opacification aid to control the optical properties of the paper or paperboard product as a wet-end additive to a papermaking operation. Using the quaternized alkanolamine fatty acid ester compound can improve the opacity of the paper or paperboard product, maintain the opacity of the paper while reducing the use of other opacification aids, such as inorganic fillers and/or pigments, and allow for a reduction in paper grammage without a compromise in opacity. The improvements in paper optical properties are achieved without adversely affecting other characteristics of the paper product such as bulk value, tensile strength, tear index, and the like.
