Definitions

  • the present invention relates to a perforated non-woven fabric and to the method for manufacturing it.
  • the non-woven fabric according to the present invention can be applied to the production of products in which it is necessary to have a layer which allows the flow of liquid through perforations provided therein.
  • the present invention can be advantageously used in the fields of sanitary towels and diapers in general, both for children and for incontinent adults.
  • heated rollers provided with protrusions, which simply compress the underlying material until they pierce it, are used for perforation.
  • a drawback of such method is that a certain difficulty is encountered in piercing the material by means of a simple passage below the pressure of a roller with protrusions having a square, circular, elliptical or rectangular profile, as revealed by the attempt to accelerate the operation by preheating the material before it enters below the rollers, described in WO2004/087384 .
  • the aim of the present invention is to provide a non-woven fabric in which holes are provided which are certainly regular, uniform, clearly defined, identical to each other, and are bonded in a heat-sealed three-dimensional structure, in order to obtain an article which is solid and withstands friction and use.
  • thermoplastic fibers which contains to a minimum extent thermoplastic fibers and is treated with hydrophobicity systems by means of techniques which are known in the textile field, and the corresponding perforation method, are provided.
  • a non-woven fabric which is constituted by cotton and/or viscose and/or Lyocell and contains bonding agents such as polypropylene or polyethylene or polylactic acid, and the perforation has been provided by means of a roller provided with V-shaped hot needles.
  • the main advantage is that the hot needles inserted in the fabric with thermoplastic fibrous do not press the fibers but widen them, and since the needles are hot, the holes melt and solidify.
  • Another advantage is that by perforating the fabric with the V-shaped hot needle, a funnel-shaped hole is formed in the fabric with the thermoplastic fibers and remains impressed within the fabric, consequently providing a one-way hole which facilitates the entry of the liquid but hinders its return.
  • Another advantage of the perforation method according to the invention is that a certain three-dimensional effect is obtained in the non-woven fabric, increasing the thickness of the material proximate to the holes, and this fact allows a spacing of the perforated non-woven fabric from the underlying layers, which are normally moist during use. An air pocket is thus provided between the liquid storage region and the upper perforated non-woven fabric, providing a more pleasant sensation for the user and giving the user the perception of dryness more effectively.
  • a non-woven fabric which has a high percentage of natural fibers of cotton or viscose or a mixed fabric of cotton and viscose is used which contains a small portion of polypropylene or of thermoplastic synthetic fibers, such as polyethylene or polyesters or polyolefins in general, or polylactic acid, which is preferred because it is biodegradable.
  • Cotton and viscose are absorbent materials, and therefore upon contact with the skin, if soaked with liquid, they would give a feeling of wetness.
  • the fabric is treated so as to make it hydrophobic.
  • plasma treatments can be used, because they reduce significantly the quantity of chemical products used. This operation renders the underlying material, cotton or other, impermeable.
  • the treatment should be extremely delicate, because a large quantity would make the non-woven fabric completely water-repellent and no longer able to perform its absorption task.
  • This treatment can be performed with known methods suitable to allow a minimum application of impermeabilizing chemicals to adjust the hydrophobicity of the surface fibers, such as for example machines for surface plasma spreading, impregnation, spraying, or by means of a bath with silicone or fluorocarbon resins, or with a surface treatment by means of a graining print.
  • the fabric thus treated is passed, after drying, between two rollers, one of which is provided with heated needles, which preferably have a length on the order of 6 to 10 mm and a diameter from 1 to 1.2 mm at their base, which becomes zero at the tip, having a V-like shape.
  • the other roller is covered on its surface with bristles or with a soft material such as silicone rubber, in order to allow the needles to penetrate the non-woven fabric.
  • thermoplastic fibers in a mixture of 2 to 50%, but lower percentages, from 2 to 15%, are preferably adopted.
  • the non-woven fabric can weigh from 15 to 70 g/m2.
  • the non-woven fabric has been provided with 95% cotton and 5% polylactic acid, with a weight of 35 g/m2, in order to obtain a product which is 100% biodegradable.
  • Figure 1 is a sectional view of the result of a non-woven fabric 10 perforated according to the invention.
  • funnel-shaped holes 11 that form in the non-woven fabric 10 have a wider inlet 15 and a narrower outlet 16, which hinders the unwanted reverse flow of the liquid.
  • Figure 2 illustrates a roller 12 with radial needles 13.
  • a roller 14 is arranged opposite the roller 12 and is covered by a flexible surface layer with bristles or soft material.
  • the non-woven fabric 10 is inserted between the two rollers 12 and 14, and by virtue of the flexibility of the covering of the roller 14 the needles 13 can penetrate the non-woven fabric 10, passing through it.
  • the provided holes 11 remain permanent, because they are provided by melting, with a clearly solidified perimetric surface.
  • the protrusions 17 keep the non-woven fabric 10 raised with respect to the underlying liquid absorption layer, giving the user a constant sensation of dryness even when the underlying layer is moist or even wet.
  • Figure 4 illustrates an arc of a roller with the needles, according to the present invention.
  • the needles 13 arranged radially on the perimeter of the roller.
  • the needles are arranged in rows along radial planes, i.e., planes which pass through the axis of the roller 12, in succession, for example at a distance of 2 mm, the rows being mutually spaced in a perimetric direction, for example at a distance of 2 mm.
  • the present invention uses a non-woven fabric made of natural fibers such as cotton, preferably anallergic cotton, and/or with the addition of thermoplastic fibers such as PLA in order to obtain a ply of fibers which is bonded in the most natural manner and with the softest textile handle (spunlace), and therefore the naturally absorbent fibers are prevented from getting wet with a water-repellent treatment; then the non-woven fabric is perforated mechanically in order to make the liquids flow out into the underlying absorbent seat.
  • natural fibers such as cotton, preferably anallergic cotton
  • thermoplastic fibers such as PLA
