Definitions

  • the invention relates to tissue or non-woven products, especially comprising several plies and suitable as hygiene or wiping products primarily including all kind of dry-creped tissue paper, wet-creped paper and cellulose or pulp wadding or all kinds of non-wovens, or combinations, laminates or mixtures thereof.
  • Typical properties of these hygiene and wiping products include the ready ability to absorb tensile stress energy, their drapability, good textile-like flexibility, properties which are frequently referred to as bulk softness, a high surface softness, and a high specific volume with a perceptible thickness.
  • a suitable wet and dry strength as well as an appealable visual appearance of the outer product surface is desired.
  • these hygiene and wiping products allow these hygiene and wiping products to be used, for example, as cleaning wipes such as paper or non-woven wipes, windscreen cleaning wipes, industrial wipes, kitchen paper, or the like; as sanitary products such as for example toilet paper, paper or non-woven handkerchiefs, household towels, towels, and the like; as cosmetic wipes such as for example facials and as serviettes or napkins, just to mention some of the products that can be used.
  • the hygiene and wiping products can be dry, moist, wet or pre-treated in any manner.
  • the hygiene and wiping products may be folded, interleaved or individually placed, stacked or rolled, connected or not, in any suitable manner.
  • the products can be used for personal and household use as well as commercial and industrial use. They are adapted to absorb fluids, for decorative purposes, for packaging or even just as supporting material, as is common for example in medical practices or in hospitals. In terms of their wide variety, hygiene and wiping products are now considered to be everyday products.
  • a tissue paper is defined as a soft absorbent paper having a basis weight below 65 g/rn 2 and typically between 10 and 50 g/m 2 . Its density is typically below 0.6 g/cm 3 , preferably below 0.30 g/cm 3 and more preferably between 0.08 and 0.20 g/cm 3 .
  • Moist tissue paper webs are usually dried by the so-called Yankee drying, the through air drying or the impulse drying method.
  • the fibers contained in the tissue paper are mainly pulp fibers from chemical pulp (e.g. Kraft sulfite and sulfate pulps), mechanical pulp (e.g. ground wood) , thermo mechanical pulp, che o-mechanical pulp and/or chemo-thermo mechanical pulp (CTMP) .
  • Pulps derived from both deciduous (hardwood) and coniferous (softwood) can also be used.
  • the fibers may also be or include recycled fibers, which may. contain any or all of the above categories as well as other non-fibrous materials such as fillers and adhesives used to facilitate the original paper making.
  • the tissue paper may also contain other types of fibers enhancing, for instance, strength, absorption, smoothness or softness of the paper. Tissue paper may even be converted to the final tissue product in many ways, for example, by embossing or laminating it into a multi-ply product, rolled or folded.
  • non-woven ISO 9092, DIN EN 29092
  • non-woven a large number of extremely varied production processes are used, such as the air-laid and spun-laced techniques as well as wet-laid techniques.
  • the non- woven includes mats, non-woven fabrics and finished products made thereof.
  • Non-wovens may also be called textile-like composite materials, which represent flexible porous fabrics that are not produced by the classic methods of weaving warp and weft or by looping.
  • non-wovens are produced by intertwining, cohesive or adhesive bonding of fibres, or a combination thereof.
  • the non-woven material can be formed of natural fibres, such as cellulose or cotton fibres, but . can also consist of synthetic fibres, such as Polyethylene (PE) , polypropylene (PP) , polyurethane (PU) , polyester, nylon or regenerated cellulose, or a mix of different fibres.
  • the fibres may, for example, be present in the form of endless fibres of pre-fabricated fibres of a finite length, as synthetic fibres produced in situ, or in the form of staple fibres.
  • the non-wovens according to the invention may thus consist of mixtures of synthetic and cellulose fibrous material, e.g. natural vegetable fibres (see ISO 9092, DIN EN 29092) .
  • WO 98/37794 discloses a rolled and folded napkin which facilitates the withdrawal of napkins from a dispenser and which allows an effective storage. The napkin is intended to be unfolded for use. Dispensing problems are also solved by GB-2250729 A for dispensing from a stack of towels. Similarly, WO 96/26664 relates to dispensing problems. Special folds are made only for this purpose .
  • US 5,023,126 A describes composite towels and a method for making composite towels, comprising of a composite product including one surface formed by smooth tissue and an opposite surface formed by an absorbent dry-formed fabric product.
  • the connection between the layer of fibre material and the layer of tissue on a forming wire is made by a binder. Then, the thus achieved product is folded in order to obtain a towel of a type which can be dispensed from a towel dispenser with a facility of conventionally folded towels.
  • US 4,582,743 A describes a toilet paper which has greater thickness in its central area and at the edges in order to give it the required wet strength. This greater thickness is achieved by folding a single-ply paper sheet in accordance with the drawings. Folding is only made for this purpose.
  • US 4,043,845 A describes a multi-layer article and a process and apparatus for its manufacture.
  • This multi-layer article is made such that it comprises at least two thicknesses, obtained by folding a single continuous web or strip of said material. The overlapping portions (by folding) are fixed one on top of the other so as to form a multi-layer web or strip . Adhesive means are applied to the strip in order to fix the loop portions being overlapped relatively one to another .
  • said multi-ply configuration is made by at least one folding of at least one ply sheet of tissue material.
  • This folding there are less possibilities for delamination because a bonding is avoided at the folded ends or edges .
  • the folding is made to achieve a thicker and more absorbent product with more than one ply.
  • the product is to be used in its folded shape. There is a decreased stiffness and an increased bulk present.
  • glue there is any toxic behaviour avoided and ply bonding is improved, when coated products are used, especially products coated with lotions.
