example 1 to 11 and comparative example 1 to 5

[0102] In Examples 1 to 11 and Comparative Examples 1 to 5, as shown in Table 1, the first intermediate layer and the second intermediate layer may be selectively provided under the topsheet. Neither the topsheet, the first middle layer nor the second middle layer were processed to have roughness such as wrinkles. In addition, none of these sheets have liquid passage holes unless otherwise specified.

[0103] In Examples 1 to 11, the topsheet, the first middle layer and the second middle layer were selected from the following four spunbond nonwoven fabrics. Table 2 shows the measured hue, lightness and chroma of each spunbonded nonwoven fabric facing the body without any other thin layer placed on the undergarment surface. Here, the hue, lightness and chroma are average values ​​of three measurements performed using a photometer "CR-300" manufactured by MINOLTA Co., Ltd.

[0104] The pink spunbond non-woven fabric is made of fibers (2.2 decitex / dtex) obtained by extruding po...

example 1

[0107] The top sheet and the first middle layer are made of pink spunbonded nonwoven fabric (basis weight: 25g / m 2 ).

[0108] For the moisture-absorbing layer, spun-bundle wet laying non-woven fabric can be used (basis weight: 38g / m 2 ), the non-woven fabric is made of 55% 1.39 decitex 44mm viscose rayon fiber, 30% 1.44 decitex 38mm polyethylene terephthalate (PET) fiber and 15% 1.67 decitex 45mm polypropylene (PP) fibers are mixed and made with water stirring / water flow interweaving (HYDROENGANGLE). Colorants of any other color than white are not used in the absorbent layer material. Viscose rayon has a natural color that does not change color when it is manufactured, but it is bleached due to the addition of inorganic fillers in PET and PP fibers. The measured hue, lightness and chroma of the absorbent layer were the same as in Examples 12 and 13. In all examples and comparative examples, the same spun non-woven fabric was used for the absorbent layer.

example 2

[0111] The second middle layer, the first middle layer and the top sheet are made of pink spunbond non-woven fabric (basis weight: 25g / m 2 ). That is to say, pink spunbonded nonwoven fabric (basis weight: 25g / m 2 ) of three thin layers stacked on the hygroscopic layer. The measured body-facing Munsell brightness was 8.70. (Example 3)

Abstract

Disclosed is a colored absorbent article to be attached to an inner side of an undergarment matching in color with the article. The absorbent article has a body surface for facing the skin of a wearer and a garment surface for facing the inner side of the undergarment. The absorbent article includes a topsheet appearing on the body surface. The topsheet is a nonwoven fabric formed of only colored fibers that are at least one kind of fibers selected from synthetic resin fibers, semi-synthetic fibers and regenerated fibers. When measured for the body surface of the absorbent article, a Munsell value is in a range of 5.7 to 9.3.

Description

technical field [0001] The present invention relates to an absorbent article for use with an undergarment which is color coordinated with the absorbent article. In particular, the present invention relates to colored absorbent articles which act as pads and which provide good concealment of vaginal discharges and good visibility of menstrual blood. Background technique [0002] Absorbent articles secured to the crotch of women's underwear include pantiliners, which are primarily intended to receive vaginal discharges, but also serve as sanitary napkins and incontinence pads. Traditional pads are used to absorb relatively large volumes of vaginal discharge so that the vaginal discharge does not leak through the pad so that it does not cause discomfort to the genitals (pubic area) or the skin around the genitals . [0003] In recent years, more and more users have chosen to use panty liners even when the amount of vaginal discharge is relatively small. These users use the p...
