Description

Absorbent article containing elastomer

Technical Field

The utility model relates to an absorb articles for use technical field, more specifically relates to an absorb articles for use that contain elastomer.

Background

Disposable absorbent articles, such as pull-ups, disposable diapers, training diapers, adult incontinence articles, and the like, are everyday articles for special populations and are primarily intended to store and isolate fecal material from the body, clothing, and the like of the user. The elastic body is required to be arranged on the waistline of the existing disposable absorption article, and the elasticity of the waistline of the paper diaper or the pull-up diaper is ensured by utilizing the resilience property of the elastic body so as to prevent the waistline from loosening. However, the elastic body in the waistline is fixed by using glue, the comfort level of the waistline is affected by excessive use of the glue or improper use of the glue, the waistline is hard, or the elastic body is deformed due to uneven stress, so that the use feeling of a user is affected. On the other hand, after the excrement is stored in the absorption part, the weight of the absorption part is increased, the absorption part generates a drooping feeling, and the absorption part is easy to slide down or expose out of shorts or short skirts, so that the embarrassment of exposure exists, and needs to be further improved.

For example, chinese patent application CN106859856A discloses a method for applying and fixing rubber band glue of pull-up pants with warp, which comprises the following steps: spreading and spreading the non-woven fabric of the trouser body base layer to determine an X-shaped rubber band area; six rubber coating areas are arranged in the peripheral areas of four end points of the X-shaped rubber band area, the waist crossing area and other areas except the upper edge area and the lower edge area; connecting parts are reserved on the side surfaces of the gluing areas at the four end points respectively; scraping glue on the first five gluing areas, spraying glue on the sixth gluing area, and fixedly pasting the rubber band; then covering non-woven fabrics on the rubber band, and fixing the rubber band between the multiple layers of non-woven fabrics; and carrying out hot pressing on the corresponding connecting parts. Although the method effectively saves the rubber band glue, the pull-up diaper glue is used more, which is easy to cause that the waist is hard or the elastic body is deformed due to uneven stress; because the elastic body in the waistline is fixed by all the glue, the space for free extension is reduced, the retraction is unnatural, the thigh part feels tight, the flexibility and the comfortable feeling of the pull-up pants are reduced, and the use feeling of a user is influenced.
