Definitions

  • the present invention refers to a tissue paper for hygienic and sanitary use, of the type comprising one or more plies of paper.
  • An aim of the present invention is to provide a tissue paper for hygienic and sanitary use that has a series of tactile and fragrant effects differing from conventional tissue papers, while also exhibiting the necessary capacity to absorb water and other liquids.
  • Another aim of the present invention is to provide a tissue paper for hygienic and sanitary use that offers ductile workability, with particular reference to printing and/or embossing procedures.
  • tissue paper for hygienic and sanitary use characterized in that it comprises a base support comprising at least one moisture-resistant polymer resin and a mixture of fibres comprising cellulose fibres and animal milk protein fibres, said animal milk protein fibres being present in said base support up to a 50% maximum content by weight.
  • the animal milk fibres are treated with an agent that prevents the dissolution thereof.
  • the insolubilization of the milk fibres can take place by enzymatic insolubilization, by administering heat or by means of chemical reactions such as the reaction of the whey with phosphoric acid so as to form insoluble phosphates, or with polycarboxylic acids such as citric acid or butane tetracarboxylic acid.
  • the base support has a surface treatment with a solution based on starch and/or sorbitol and/or glycerol and/or polyvinyl alcohol and/or acrylic, polyurethane and/or styrene- butadiene polymers.
  • the tissue paper thus conceived creates a particular velvet-like feel of softness accompanied by a particular fragrance of milk.
  • the present invention also concerns a method for manufacturing a tissue paper for hygienic and sanitary use, comprising the steps of:
  • the surface of the base support is treated with a solution based on starch and/or sorbitol and/or glycerol and/or polyvinyl alcohol and/or acrylic, polyurethane and/or styrene- butadiene polymers.
  • tissue paper for hygienic and sanitary use and the relative manufacturing procedure are defined in the dependent claims.
  • the invention thus provides a tissue paper for hygienic and sanitary use that is velvety, soft and milk-scented, owing to a pulp specially devised for realizing a base support and to a special surface treatment.
  • the production method also makes it possible to mix the fibres obtained from animal milk proteins with conventional paper pulps.
  • the animal milk proteins comprise at least casein.
  • the animal milk proteins are derived from the milk of ruminant artiodactyls.
  • animal milk protein fibres are derived from sheep or bovids, among which cows, goats and yaks.
  • the tissue paper for hygienic and sanitary use of the invention proves to be perfectly printable with high printing quality and makes it possible to achieve particular graphic effects that are difficult to achieve with conventional tissue papers.
  • the tissue paper for hygienic and sanitary use comprises a base support and a surface treatment of the base support.
  • the base support is made up of a mixture of cellulosic fibres and animal milk protein fibres of varying percentages and it contains various polymeric substances, among which at least one polymeric resin, adapted to give the mixture of fibres moisture resistance, and other polymeric substances adapted to give the mixture strength (when dry or wet).
  • the polymeric resin for providing moisture resistance preferably consists of epochlorohydrin and the other polymeric substances for providing strength comprise colophony-based and/or alkyl- ketene-dimer-based and/or acetylsuccinic-acid-based resins, and/or modified starches.
  • the surface treatment consists of a solution based on glycerol and/or sorbitol and/or starch and/or polyvinyl alcohol and/or acrylic, polyurethane and/or styrene-butadiene polymers.
  • the grammage of the tissue paper ranges between approximately 10 and approximately 400g/m 2 .
  • the tissue paper for hygienic and sanitary use described hereinabove is realized using the following method.
  • an aqueous pulp comprising a mixture of cellulose fibres and animal milk protein fibres, the polymeric substances (resins for providing moisture resistance and strength), among which colophony-based and/or alkyl-ketene-dimer-based and/or acetylsuccinic-acid-based and/or epochlorohydrin-based resins, and/or modified starches.
  • Water is then removed from the pulp so as to form the base support of the paper material having animal milk protein fibres in a percentage varying up to 50% by weight.
  • aqueous solution for example a 10% by weight aqueous solution of starch, and/or 10% by weight of glycerol, and/or 10% by weight of sorbitol and/or 5% by weight of acrylic adhesive, or similar adhesives.
  • the method can comprise a step of mechanically treating the surface, particularly an embossing step.
