| titleOfInvention | Diaper with back-to-back transition web facing |
| abstract | 1473691 Web formers; non-woven fabric with a fibre length gradient JOHNSON & JOHNSON 8 July 1974 [9 July 1973] 30096/74 Headings DIN and D1R [Also in Division A5] A diaper comprises a porous fibrous facing layer including an inner stratum 13 of predominately short fibres overlaid and underlaid by outer strata having a greater proportion of long fibres than the inner stratum, the facing layer being delaminatable along the short fibre stratum. The diaper also has an absorbent pad and a water-imprevious backing sheet. A roll of short fibres 41 feeds a source of short fibres to a grinding mill 42 from which a fibre stream is blown onto a belt 43 as a layer 44 which passes under a compacting roll 46 to emerge as a self sustaining web. The web is further compressed by calender rolls 47 and its upper surface moisturised by means of a nozzle 48 and formed into a skin 51 by calender rolls 49. Densified portions are formed by an embossing roll 52 and the web contacts a web of facing material 16 and the backing sheet 12, lines of adhesive being applied from an applicator 59. The facing layer is formed by air-laying two separate fabrics 30, 30' which are juxtaposed by a combining means 77. Fibres are air-laid on a foraminous belt 90 by a suction box 91, the belt 90 having three single lickerins, the first depositing a long fibre layer, the second a short fibre layer downstream and the third a long fibre layer yet further downstream, the face of the layer adjacent belt 90 being long fibre enriched and the other short fibre enriched. Using a conveyer 78 the combined web is passed to a bonding station where an aqueous dispersion of acrylonitrile binding agent and a surfactant are supplied from a source 79, and to a drying station 81 where it is dried at 82 and the exterior surface heated at 83 and 84. After complete drying the web enters the diaper production stream at the position of roller 85 which brings it into contact with the absorbent web of the diaper. The short fibres are preferably wood or cotton. The long fibres in one fabric may be rayon and in the other polyester or polyvinyl alcohol. |
