Abstract

The present invention provides a method of manufacturing an wearing article including: a front waist part which includes a left-front end and a right-front end; and a rear waist part which includes a left-rear end and a right-rear end forming, together with the left-front end and a right-front end, a left-side sealing portion and a right-side sealing portion. In the method, the left-side sealing portion in a layered state in which a fiber-supplemented sheet formed from a nonwoven fabric is layered on an elastic fiber sheet is formed in at least a portion of the article, the right-side sealing portion in the layered state is formed in at least a portion of the article, and, in at least a portion of the elastic fiber sheet, the fiber-supplemented sheet is not layered such that airflow is allowed to pass through the elastic fiber sheet.

Dependent claims

A method of manufacturing a wearing article that covers a front abdominal part, a crotch, and a back part of a wearer, the wearing article including a front waist part including a left-front end and a right-front end in an article width direction along a waist of the wearer and covering the front abdominal part of the wearer, and a rear waist part including a left-rear end and a right-rear end in the article width direction forming a left-side sealing portion and a right-side sealing portion, respectively, by being joined to an inner side surface in a state of being layered on the inner side surface of each of the left-front end and the right-front end and covering the back part of the wearer, the rear waist part being coupled to the front waist part at a portion positioned in the crotch of the wearer, the method comprising:

a preparation step of preparing an elastic fiber sheet formed of a nonwoven fabric including an elastic fiber formed of a fiber having elasticity, and an extensible stretching fiber having elasticity smaller than the elasticity of the elastic fiber, the nonwoven fabric subjected to drawing processing;
a left-side sealing portion formation step of forming the left-side sealing portion by superimposing and joining the left-front end and the left-rear end of each wearing article in a layered state where a fiber-supplemented sheet formed of a nonwoven fabric is layered on the elastic fiber sheet in at least a part of a portion that is a formation target of the left-side sealing portion;
a right-side sealing portion formation step of forming the right-side sealing portion by superimposing and joining the right-front end and the right-rear end of each wearing article in the layered state in at least a part of a portion that is a formation target of the right-side sealing portion;
and
a clipping step of clipping the front waist part and the rear waist part from the elastic fiber sheet,
wherein the fiber-supplemented sheet is not layered on the elastic fiber sheet in at least a part of the elastic fiber sheet after the left-side sealing portion formation step and the right-side sealing portion formation step, and airflow through the elastic fiber sheet is allowed.

A wearing article that covers a front abdominal part, a crotch, and a back part of a wearer, the wearing article comprising:

a front waist part including a left-front end and a right-front end in an article width direction along a waist of the wearer and covering the front abdominal part of the wearer;
and
a rear waist part including a left-rear end and a right-rear end in the article width direction forming a left-side sealing portion and a right-side sealing portion, respectively, by being joined to an inner side surface in a state of being layered on the inner side surface of each of the left-front end and the right-front end and covering the back part of the wearer, the rear waist part being coupled to the front waist part at a portion positioned in the crotch of the wearer,
wherein the front waist part and the rear waist part include an elastic fiber sheet formed of a nonwoven fabric including an elastic fiber formed of a fiber having elasticity, and an extensible stretching fiber having elasticity smaller than the elasticity of the elastic fiber, the nonwoven fabric subjected to drawing processing,
in the left-side sealing portion, in at least a part of the left-side sealing portion, the left-front end and the left-rear end of each wearing article are superimposed and joined in a layered state where a fiber-supplemented sheet formed of a nonwoven fabric is layered on the elastic fiber sheet,
in the right-side sealing portion, in at least a part of the right-side sealing portion, the right-front end and the right-rear end of each wearing article are superimposed and joined in the layered state, and
the fiber-supplemented sheet is not layered on the elastic fiber sheet in at least a part of the elastic fiber sheet, and airflow through the elastic fiber sheet is allowed.
