Definitions

  • the present invention relates to a hygiene product, for example a tampon or sanitary towel, which comprises i liquid-absorbing fibres in the form of a non-woven material, ⁇ and to a method for producing such a hygiene product, in whic
  • the liquid-absorbing fibres are formed into a non- woven material, which -is then formed into said product.
  • Present day tampons are produced from a non-woven material containing liquid-absorbing cotton fibres or viscose-rayon fibres, or a mixture thereof. 10
  • One problem with the use of known tampons is that fibres tend to loosen from the tampon and remain in the vaginal passage of the wearer, when the tampon is removed. This can ⁇ lead to irritation in the vagina, and to other problems_ of a medical nature.
  • the object of the present invention is to provide a method of counteracting the tendency of fibres to loosen from such hygiene products.
  • the concept of the invention is to bond the fibres in * 30 the outer layer of the tampon, so as to reduce the possibility of said fibres becoming free therefrom.
  • This concept is ful ⁇ filled by supplying meltable fibres to the liquid-absorbing fibres, such that said meltable fibres are located in at least the outer layer of the non-woven material comprising 35 said liquid-absorbing fibres and said meltable fibres; and by applying heat to said outer layer in a manner to cause the meltable fibres to fuse together to form a network which binds the liquid-absorbing fibres, such as to counteract the release of fibres therefrom.
  • This heat treatment of the non- woven material can be effected before the tampon is formed or subsequent thereto, said tampon being formed by rolling or dragging the non-woven material to tampon form.
  • the meltable fibres suitably constitute 5-50% by weight, preferably 20-40% by weight, of the total fibre weight of the tampon.
  • the meltable fibres may comprise synthetic polymers or co-polymers, such as polyethylene, polypropene, polyamide, or polyester.
  • the meltable fibres may also be heterophyllous, i.e. comprise a core of one polymer and an outer sheath of another polymer of lower melting point than the former, or two mutually adjacent layers of mutually different polymers or co-polymers of mutually different melting points.
  • the preformed tampon can be pressed to its final form.
  • the non-woven material can also be needled in a conventional manner, so as to improve binding of the liquid- absorbing fibres.
  • Example III 70% by weight viscose rayo ⁇ fibre having a fineness of 3 denier and a fibre length of 38 mm was mixed with 30% by weight polypropene fibre of the same fineness as the rayon fibres and a fibre length of 50 mm.
  • the fibre mixture was processed in accordance with Example I, with the exception that the pre-formed tampon was heated to 180°C.
  • Example III
