Definitions

  • the absorbent core of the invention can be made of any suitable liquid-absorbent material.
  • suitable liquid-absorbent materials suitable for use as the absorbent core include comminuted wood pulp which is generally referred to as airfelt; creped cellulose wadding; absorbent gelling materials including superabsorbent polymers such as hydrogel- forming polymeric gelling agents; chemically stiffened, modified, or cross-linked cellulose fibers; meltblown polymers including co-form; synthetic fibers including crimped polyester fibers; tissue including tissue wraps and tissue laminates; capillary channel fibers; absorbent foams; absorbent sponges; synthetic staple fibers; peat moss; or any equivalent material; or combinations thereof.
  • the topsheet used in there can be formed film or nonwoven film.
  • ⁇ [(L*2-L*i) 2 + (a* 2 -a* 2 + (b* 2 -b*i) 2 ] 1/2 "Formula 1"
  • the colored portion under the topsheet of the inventive samples was used to determine L* 2 , a* 2 , b* 2
  • the colored portion under acquisition layer and topsheet together as measured through the cover layer was used to determine L* 1 ,a* 1 and b*i.
  • ⁇ was then calculated from these values.
  • Color measurements required to calculate ⁇ can be made using a tristimulus colorimeter (Minolta Chromameter(R) CR300) using the CIE (International Commission on Illumination) L*a*b* color coordinate standard.
  • the term "uncolored", “non-colored", “white” or the like, as used herein, means those colors having an L* value of at least 90, an a* value equal to 0 + 2, and a b* value equal to 0 +- 2.
  • Embossed channels and folds should not be included in zones of measurement as they may skew the proper results. Measurements should not be made on sites where the border of two shaded portions are overlapping.
  • Sample 2 is prepared by using formed film topsheet layer, air laid acquisition layer and one tone dark blue colored absorbent core.
  • Sample 3 is prepared by using non-woven topsheet layer, air through acquisition layer and one tone dark blue colored absorbent core.
  • Sample 4 is prepared by using non-woven topsheet layer, air laid acquisition layer and one tone dark blue colored absorbent core.
  • Sample 5 is prepared by using formed film topsheet layer, air through acquisition layer and one tone dark violet colored absorbent core.
  • Sample 6 is prepared by using formed film topsheet layer, air laid acquisition layer and one tone dark violet colored absorbent core.
  • Pads should be measured laying flat over the 0.70 inch aperture on the instrument. A white tile should be placed behind the pad.
  • Table I above clearly shows the AE*s obtained from different samples. Table clarifies that; both samples formed from formed film and non-woven types of topsheet used with air laid acquisition layer show better penetration of light compared to airthrough acquisition layer used samples. Therefore air laid acquisition layer type is prefered in the present invention.
  • Opacity is a measure of the capacity of a material to obscure the backsground behind it.
  • the value for opacity is obtained by dividing the reflectance obtained with a black backing (RB) for the material, by the reflectance obtained for the same material with a white background (RW). This is called the contrast ratio (CR) method.
  • the specimens must be conditioned under standart TAPPI conditions (73 °F(22.8 °C); 50% RH) until equilibrium is reached, and measured under those conditions.
  • the material used for the test is the surfactant-treated topsheet material.
  • the colorimeter is calibrated using the standard gloss black glass and gloss white tile supplied with the instrument according to the manufacturer's instructions.
  • the topsheet is placed on the sample holder and inserted into the colorimeter and color scale Y value is measured.
  • topsheet and acquisition layer together is placed on the sample holder and inserted into the colorimeter and color scale Y value is measured.
  • Obtained color scale Y values are set into the opacity Formula 2 to obtain opacity values in percent.
  • the specimen is placed on the sample holder and inserted into the colorimeter according to the manufacturer's instructions.
  • the machine direction of the specimen should be aligned front to back in the instrument.
  • the Y reading is recorded to the nearest 0.1 unit.
  • the procedure is repeated 10 times on different parts of the sample and the avarega value is taken for the calculations.
  • Table II above clearly shows the results of the opacity tests of different samples. It can be seen that, the samples have sufficient transparency to be seen clearly from the top surface of the articles.

Abstract

La présente invention concerne un article d'hygiène féminine comprenant une feuille supérieure, une feuille inférieure, une couche d'acquisition et une couche centrale. La couche centrale définit une zone centrale entre la feuille supérieure et la feuille inférieure qui est complètement recouverte par la feuille supérieure. La couche d'acquisition est placée sur la couche centrale et recouvre de 65 à 85 % de la couche centrale. Une couleur, autre que blanche, est imprimée sur la couche centrale de l'article d'hygiène féminine, le motif imprimé étant visible à travers le côté face de la feuille supérieure. Au moins 90 % de la couche centrale présente une partie colorée sous la couche supérieure et au moins de 65 à 85 % de la partie colorée se situe sous la couche d'acquisition et la couche supérieure. Selon la présente invention, un agent colorant unique est appliqué sur la surface supérieure de la couche centrale et une valeur L*a*b* différente de la partie colorée est obtenue lorsqu'une mesure est effectuée depuis la surface d'observation de la feuille supérieure. La différence de couleur des parties de l'impression qui sont situées sous la couche supérieure et la couche d'acquisition et la couche supérieure seule fournit un effet de nuance. À terme, cela créer une perception de profondeur à l'intérieur de l'article absorbant pour un utilisateur regardant la surface d'observation de la feuille supérieure.
