Definitions

  • the invention relates to a process for producing multi-layered tissue paper products, in particular paper handkerchiefs, with increased softness and to a lotion.
  • the addition of the softener solution in the wet region of the paper-making machine has drawbacks.
  • the active ingredients are distributed over the entire volume of the layered web of tissue, so a large amount of softener has to be added with respect to the quantity of paper fibre.
  • the positively charged molecules of the quaternary ammonium compound present in the solution have to neutralise the negatively charged fibres in the cellulose pulp. This leads to increased consumption of softener solution.
  • a quantity of only 0.4 kg remains in the product as active ingredient with an addition of, for example, 11 kg of active softener per tonne of paper pulp.
  • the known process therefore involves great wastage owing to the addition of the softener solution "at the wet end" of the production process.
  • a lotioned tissue paper is disclosed in WO-A-97/06307, published on 20 th February 1997. This discloses a polyol polyester emollient and an immobilizing agent to immobilize the emollient on the surface of the tissue paper web.
  • the object of the invention is to provide a process for producing multi-layered tissue paper products with increased softness, which is accompanied by more economical consumption of softener substances and to provide a lotion.
  • the softening lotion is advantageously applied, by the printing of the web of product, virtually only superficially where it imparts pleasant tactile properties to the paper product.
  • the consumption of softening lotion can be halved, for example, in relation to the prior art in that 5.5 kg per tonne of paper are applied. Owing to the printing process, this quantity is found virtually without loss on the end product.
  • Corresponding titration tests on a four-layered paper handkerchief have shown that, of this quantity, 5.3 kg per tonne of paper are found on the two outer layers whereas the softener content is only 0.1 kg per tonne of paper in the two inner layers.
  • the specified chemical composition of the softening lotion affords various advantages some of which are manifested in conjunction with the printing process.
  • a range of contents of siloxane foam suppressor which is much higher than in the state of the art is used.
  • This foam suppressor is traditionally used merely to suppress the foam formed on the product by pressure during the packaging process.
  • small proportions of the foam suppressing agent suffice.
  • the proportion of siloxane is typically 0.01% by weight there, that is about 1/10 of the proportion specified in the case of the invention. This high proportion of siloxane counteracts foaming during the printing process which stresses the product much more than the above-mentioned packaging process.
  • the softening lotion is insensitive to shearing and so-called droplet penetration is not impaired owing to the great addition of siloxane foam suppressing agent, contrary to expectations.
  • Polydimethyl siloxane which is mentioned in the state of the art for this purpose, is a preferred foam suppressing agent.
  • Intaglio cylinders which apply the softening lotion to the external sides of the multi-layered web of product are advantageously used for the printing process. Weights per unit area in the range of 0.5 to 6.0 g/m2 on each external side are to be selected for the desired softening effect.
  • Layered webs of a tissue paper are produced in a quite conventional manner on a paper-making machine to produce a multi-layered paper handkerchief. Further description is unnecessary. It should merely be noted that the weight per unit area of the layered webs is in the range of about 12 to 18 g/m2 in each case.
  • the dry web of product is finally guided through a pair of intaglio cylinders which applies a softening lotion having a weight per unit area of 1.7 g/m2 in each case to the surface of the two external sides of the web of product.
  • the softening lotion has the following chemical composition:
  • the polyethylene glycol can be obtained as a commercial product known as "PEG 4000” made by BASF, Ludwigshafen, Germany. The same product is sold by the name “PEG 4050” as a 50% solution in water. If the polyhydroxy softener is used in this form, the proportions in the chemical composition of the softening lotion according to the invention should be doubled accordingly.
  • Aloe vera powder is a highly concentrated form of aloe vera of which the concentration is about 200 times that of the liquid obtained by squeezing aloe vera leaves.
  • the above-mentioned softening lotion in fact per se possesses very good bactericidal properties. This is not only because of the pH-value, but rather in view of the nature of the active itself and the polyhydroxy compound.
