〔産業上の利用分野〕
本発明は使いすておむつに関する。更に詳しくは横もれ
を改善した使いすておむつに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to disposable diapers. More specifically, the present invention relates to a disposable diaper with improved side leakage.

漏れを防ぐ工夫がなされている。Conventional disposable diapers have an absorbent body between a liquid-permeable top sheet and a liquid-impermeable back sheet, and have stretchable elastic bodies on both side edges of the absorbent body to create a seal with the crotch. Efforts have been made to prevent side leakage.
又横漏れ防止のためサイドフラップを疎水性にした使い
すておむつも知られている。Disposable diapers with hydrophobic side flaps to prevent side leakage are also known.
更にサイドフラップ上を基端とし、その上方へ伸びた疎

知られている。Furthermore, a second flap made of a hydrophobic non-woven fabric is formed with the base end above the side flap and extends upward, and a stretchable elastic body is provided inside the upper part of the second flap to maintain sealing properties with the crotch and to allow ventilation of the non-woven fabric. There are also known diapers that utilize sex characteristics to improve swelling.

の面では多少劣っており漏れが発生しやすい。Although this second flap part is hydrophobic, it is made of porous non-woven fabric, so it is somewhat inferior in terms of waterproofness compared to conventional diapers in which stretchable elastic bodies are attached directly to the side flap parts. Leaks are likely to occur.
第二フラップ部は疎水性不織布が２重になっているため

不織布を通過し外へ漏れる欠点かあ、った。The second flap part has two layers of hydrophobic nonwoven fabric, which provides strong waterproof properties, but the side flap part has one layer of hydrophobic nonwoven fabric.
It's heavy and the waterproofness is a little poor. In addition, near the base end of the second flap of the side flap, there is a hydrophilic top sheet between the hydrophobic nonwoven fabric and the back sheet, and urine passes through the hydrophilic top sheet portion to the single layer of the hydrophobic nonwoven fabric of the side flap. The drawback is that it passes through and leaks out.

とを目的とするものである。The present invention has a back sheet and side flaps made of a hydrophobic nonwoven fabric on the outside of both lateral edges of the absorbent body, and a portion of the inner side edge of the diaper of the hydrophobic nonwoven fabric covers the entire length of the diaper in the longitudinal direction of the top sheet. The object of this invention is to prevent side leakage from the base end of the leak-proof part of a disposable diaper which is bent upward with the top as the base end and has a leak-proof part having a stretchable elastic body at the tip.

徴とする使いすてふむつである。The present invention has an absorbent body between a liquid-permeable top sheet and a liquid-impermeable back sheet, and extends outward from both lateral edges of the absorbent body, and is connected to the back sheet and a hydrophobic nonwoven fabric. The end edge of the hydrophobic nonwoven fabric in the inner side of the diaper is bent to wrap around the stretchable elastic body over the entire length of the diaper in the longitudinal direction, and the end edge of the hydrophobic nonwoven fabric is bent so as to wrap around the stretchable elastic body, and the end edge of the hydrophobic nonwoven fabric is bent so as to wrap around the stretchable elastic body. In a disposable diaper having a second flap formed of a hydrophobic nonwoven fabric extending upward from the base end, the central region of the top sheet is hydrophilic, and at least the second flap of the both side edge regions of the top sheet is hydrophilic. It is a disposable product characterized in that the region outside the proximal end of the two flaps is hydrophobic.

There is a method to make it hydrophilic.
疎水化及び親水化する方法としてはフレキソロール又は
グラビアロールにより所定のパターンに疎水化剤、又は
親水化剤を塗布する方法がある。As a method for making the material hydrophobic and hydrophilic, there is a method of applying a hydrophobizing agent or a hydrophilic agent in a predetermined pattern using a flexor roll or a gravure roll.

As hydrophobizing agents, commercially available softeners such as silicone-based and fluorine-based softeners,
Waterproofing agents, water absorbing agents, etc. can be used.
