Abstract
A disposable wearing article having an excellent rash preventing effect. The above problem is solved by a disposable wearing article including a top sheet having a skin contact region in contact with a skin of a wearer, wherein the skin contact region has, in a region to which a body fluid pervious treatment agent containing a nonionic surfactant having an amide group is applied, a glycerin-containing region to which glycerin is applied, and the top sheet has a two-layer structure of an upper layer of less than 2.0 dtex and a lower layer of 2.0 to 4.0 dtex, and is formed of a nonwoven fabric having a basis weight of 5 to 40 g/m2.
Claims3
A disposable wearing article comprising
- a top sheet having a skin contact region configured to contact a skin of a wearer,
- wherein the top sheet has a two-layer structure of an upper layer of a fineness of 1.0 to 1.7 dtex and a lower layer of a fineness of 2.1 to 3.3 dtex, a basis weight of the top sheet is 15 to 25 g/m2, and the top sheet is a hydrophilic nonwoven fabric applying a hydrophilizing agent,
- wherein the skin contact region has,
- in a region in which a body fluid pervious treatment agent is attached, the body fluid pervious treatment agent comprising a nonionic surfactant consisting of a single fatty acid alkanolamide having an HLB value of 9.5 to 14, and the body fluid pervious treatment agent not containing an anionic surfactant, a cationic surfactant, or an amphoteric ion-based surfactant,
- a glycerin-containing region to which a hydrophilic lotion containing 70 to 90% by weight of glycerin and 10 to 30% by weight of water is applied, and
- an attachment amount of the body fluid pervious treatment agent in the region in which the body fluid pervious treatment agent is attached is 0.05 to 2% by weight on the basis of a fiber weight of the top sheet,
- the glycerin-containing region in the region in which the body fluid pervious treatment agent is attached, contains 0.7 to 2.7 g/m2 of glycerin and has a size of 100 mm or more in an MD (Machine Direction) direction and a size of 5 mm or more in a CD (Cross Direction) direction, and
- an area ratio of the glycerin-containing region in the skin contact region in an unfolded state is 3% or more.
A method for manufacturing a disposable wearing article including a top sheet having a skin contact region configured to contact a skin of a wearer, comprising:
- using, as the top sheet, a hydrophilic nonwoven fabric having a two-layer structure of an upper layer of a fineness of 1.0 to 1.7 dtex and a lower layer of a fineness of 2.1 to 3.3 dtex, and having a basis weight of 15 to 25 g/m2;
- attaching a body fluid pervious treatment agent to the nonwoven fabric, the body fluid pervious treatment agent containing a nonionic surfactant consisting only of a single fatty acid alkanolamide having an HLB value of 9.5 to 14 as a nonionic surfactant, and the body fluid pervious treatment agent not containing an anionic surfactant, a cationic surfactant, or an amphoteric ion-based surfactant,
- forming a region attaching the body fluid pervious treatment agent in which an attachment amount of the body fluid pervious treatment agent is 0.05 to 2% by weight on the basis of a fiber weight;
- applying a hydrophilic lotion containing 70 to 90% by weight of glycerin and 10 to 30% by weight of water, to the region attaching the body fluid pervious treatment agent;
- and
- forming a glycerin-containing region containing 0.7 to 2.7 g/m2 of glycerin and having a size of 100 mm or more in an MD (Machine Direction) direction, a size of 5 mm or more in a CD (Cross Direction) direction, and an area ratio of the glycerin-containing region in the skin contact region in an unfolded state of 3% or more.
