Definitions

  • the present invention relates to a method for the manufacture of an absorbent material having graduated density, and to an absorbent material manufactured by this method.
  • Absorbent materials of this type are particularly suitable for use as medical or hygienic absorbents, for the absorption of body fluids, for example in surgical dressings, sanitary products and incontinence products. It is a requirement of such absorbents that they should absorb the fluid away from the surface of the absorbent in contact with the source of fluid, but that fluid strike-through, that is the passage of fluid through the surface of the absorbent remote from the source of fluid, should be delayed as much as possible. In this way, the interval between the replacement of a used absorbent with a new absorbent can be extended.
  • the disadvantage of such materials is that they are expensive to produce. Such materials have not been used as surgical dressings, but as filtration materials and as synthetic leathers.
  • the present invention thus provides, in one of its several aspects, a method for the manufacture of an absorbent material having graduated density by needling a web, characterised in that the web, before needling but after tacking, is of substantially constant density across its thickness, and in that needling is carried out so that the needles penetrate to the extent that only surface regions of the web are needled.
  • the web used in carrying out the method according to the invention may comprise a major proportion, up to 100%, of hydrophilic fibres, which may be blended with a minor proportion, preferably up to 30%, of hydrophobic fibres.
  • the hydrophobic fibres when incorporated, provide a "scaffolding" which resists compression and helps to maintain the low density structure of the centre of the material both during needling and in subsequent use, especially when the material becomes wet.
  • the hydrophilic fibres used in the web are preferably rayon, acrylic or cotton fibres, or a mixture thereof, more preferably rayon fibres.
  • the web for use in the method according to the invention may alternatively comprise 100% hydrophobic fibres.
  • the absorbency of the web is due to the structure of the material, rather than any inherent absorbency of the fibres.
  • the hydrophobic fibres used in the web are preferably polyester or polyolefin fibres, more preferably polyester fibres.
  • barbed needles are preferably used of the type which have a section without barbs close to the point of the needle and then a section which is provided with barbs.
  • Suitable needles include those marketed by Foster Needle under the reference number 15 x 8 x 40 x 3.5CB F.20 9-18-3B and those marketed by Groz Beckaert under the reference numbers 15 x 18 x 43 x 3.5 C333 G1002, G92919.
  • Needling may be carried out to a similar penetration at each surface of the web, so that a symmetrical absorbent material which can be used with either surface contacting the source fluid is obtained.
  • needling may be carried out to a different penetration at the two surfaces of the web, to provide a material having surface regions of different densities.
  • Such an arrangement of different surface densities has the effect of improving the fluid uptake while maintaining delayed strike-through.
  • the absorbent material is preferably provided with a surface covering which is non-adherent.
  • the absorbent material may be wrapped, in known manner, in a non-adherent material or may be bonded, also in known manner, to such a material, to form a composite article.
  • the composite articles manufactured in this way are particularly suitable for use as surgical dressings, sanitary towels or incontinence products.
  • the weight of the fibre layer(s) introduced into the loom is determined according to the desired weight of the final material. In practice the weight of said layer(s) is determined empirically, the feed of the fibres being controlled according to the actual weight of the final product.
  • a batt made up of one or more layers was produced from a fibre blend of 80% 1.7 dTex 51mm staple viscose fibres and 20% 5.OdTex 40mm staple polyester fibres.
  • the batt was then needled in a three-stage operation: In a first, tacking, stage the batt was passed between an up-stroking needle board and a down-stroking needle board, each fitted with 15 x 18 x 40 x 3 F222 G92919 needles marketed by Groz Beckaert. The penetration of both the top and bottom needles was 14mm. In a next following first needling stage, the thus tacked batt (or web) was passed under a single needle board fitted with a mixture of 67% 15 x 18 x 40 x 3.5 R333 G1909 needles and 33% Foster 15 x 18 x 40 x 3.5CB F20 9-18-3B needles and having a needle punch density of 83 needles/cm2 .
  • Needling was thus carried out using a downstroke only; needle penetration in this stage was 6.1mm. Thereafter in a second needling stage, the partially needled batt (or web) was passed between an up-stroking needle board and a down-stroking needle board, each fitted with a mixture of 67% 15 x 18 x 40 x 3.5 R333 G1909 needles and 33% Foster 15 x 18 x 40 x 3.5CB F20 9-18-3B needles and having a needle punch density of 329 needles/cm2 and a head speed of 509 rpm. The top penetration in this case was 4.6mm and the bottom penetration 5.6mm.
  • the final product weight was 300gsm.
  • the product was satisfactory for use as a medical absorbent, with relatively dense surface regions and a less dense central region.
  • Example 2 the same procedure, using the same needle boards, was followed as in Example 1 except that in the second needling stage the penetration by the needles of the down-stroking needle board was 0.2mm and that by the up-stroking needle board 5.6mm. Moreover in this case the needle punch density was 392 needles/cm2 and the head speed 605 rpm.
  • the final product weight was again 300gsm.
  • the products demonstrated excellent properties for use as a medical absorbent, with dense surfaces and more open centre.
  • Example 2 Again in this Example the same procedure was followed as in Example 1, except that the needle punch density in the first needling stage was 86 needles/cm2, and further in the second needling stage the penetration by the needles of the down-stroking needle board was 4.7mm and that by the up-stroking needle board 5.6mm. Moreover, in this case the needle punch density was 337 needles/cm2 and the head speed 501 rpm.
  • the final product weight was 190gsm.
  • the product was thus a material of lighter weight than the other two Examples. Such material would be suitable for a use in medical applications where the absorbency required was not so high and light weight was an advantage.
