Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は紙おむつに関する。Description: TECHNICAL FIELD The present invention relates to a disposable diaper.
（従来の技術） 従来より、おむつを使用する場合にいわゆる“おむつ
かぶれ“という問題がある。(Prior Art) Conventionally, when using a diaper, there is a problem of so-called “diaper rash”.
この“おむつかぶれ“とは一次刺激性皮膚炎と呼ばれ
るものであり、その原因としては皮膚の表面が蒸れて傷
つきやすい状態となり、おむつの表面素材と摩擦を生じ

ことによる化学的刺激等が考えられ、これらが相互に作
用して“おむつかぶれ“を発現させていると思われる。This “diaper rash” is what is called primary irritant dermatitis, which is caused by physical irritation caused by friction of the skin surface with the surface material of the diaper, causing friction, etc. Microbial irritation due to increased activity of enzymes (proteases, lipases) and bacteria, and chemical irritation due to the generation of ammonia from urea in feces and urine, etc. are considered, and these interact to cause “diaper rash”. "Seems to be expressed.

の面で使用し難い。Various studies have been made to prevent such "diaper rash". For example, a method has been proposed in which a paper diaper is provided with air permeability to reduce stuffiness by using a waterproof layer base material having ventilation holes, and a method for making the surface material less irritating. However, this method can avoid physical irritation but does not provide a solution for microbial or chemical irritation. Further, a method has been proposed in which a bactericide is added to the water-absorbing substrate to suppress the activity of bacteria and the like, but this method is difficult to use in terms of safety.
また、前記いずれの方法によっても一旦“おむつかぶ
れ“が発生した場合には、おむつを装着した状態のまま
では“おむつかぶれ“を治癒する手段がないという問題
点があった。In addition, when "diaper rash" occurs once by any of the above methods, there is a problem that there is no means to cure the "diaper rash" while the diaper is worn.
