[0178] Such as Figure 15 As shown, the row of third bonding parts 42, 42... having a long separation interval in the orthogonal direction XD may be formed between the row of first bonding parts 40, 40... and the row of second bonding parts 41, 41.... Formation of the third joining portion 42 makes it possible to form the inter-row creases R shown in the first embodiment as large creases bf that are cut off in the orthogonal direction XD. Small creases sf can be formed between the third junction part 42 and the first junction part 40, 40... row. The group of pleats in which the inter-row pleats R are disconnected makes the flexural member low in bending rigidity (easy to bend) and good in followability to body movement.

[0180] through as Figure 16 By arranging the position of the third joining portion 42 obliquely together with the second joining portion 41 as shown, a group of large pleats bf arranged obliquely can be formed, a...

Abstract

[Problem] There is no need to color the lower sheet, so that color unevenness in the appearance of the colored nonwoven fabric is less conspicuous. [Solution] The above-mentioned problems are solved by a disposable wearing article characterized by comprising a colored nonwoven fabric (100) having an exposed portion and an inner side of the colored nonwoven fabric (100). The adjacent lower sheet (120), the colored non-woven fabric (100) is a laminated non-woven fabric formed by laminating two or more layers, except for the outermost layer (101), the colored non-woven fabric (100) also has colored A colored layer (110) of a color of a first brightness other than white, the outermost layer (101) of the colored nonwoven fabric (100) has a color of a second brightness higher than the first brightness, and the lower sheet (120) The outer surface of has a color of a third brightness higher than the first brightness.

Description

technical field [0001] The present invention relates to disposable wearing articles with colored nonwoven fabrics. Background technique [0002] In disposable wearing articles such as disposable diapers, in order to obtain an appearance closer to underwear, it is known to color the nonwoven fabric forming the outer surface in a color other than white, or to color other parts (for example, refer to Patent Documents 1 and 2). . [0003] However, when a white lower sheet (nonwoven fabric or film, etc.) On the other side of the colored nonwoven fabric, unevenness in color depth (hereinafter simply referred to as unevenness in color) is conspicuous, and there is a problem that favorable aesthetics cannot be obtained. [0004] The reason for this color unevenness is that the color unevenness caused by the uneven texture (mass distribution) of the colored nonwoven fabric appears clearly due to the large color difference between the color of the colored nonwoven fabric and the col...
