Description
Technical Field
The utility model belongs to the technical field of disposable absorption articles for use. And more particularly to pull-ups provided with segmented ultrasonic bonding points.
Background
With the improvement of living standard of people, the market permeability of disposable absorption articles is continuously improved in recent years, baby diapers and baby growing pants are used as necessities of babies, sanitary napkins for women and adult diapers are main necessities of women and the like, and the disposable absorption articles are deeply entering daily life of people. The commercially available products are mainly divided into two types at present, one type is called as a three-piece type, is similar to an I shape, and is formed by bonding three-piece structures of transverse elastic waists at two sides and a longitudinal core body in the middle through glue; the other is two-piece, also known as one-piece, adult pants, which are integrally formed with the transverse portions at the ends and the longitudinal portion in the middle.
At present, the disposable absorbent article needs to be provided with an elastic body on the waistline, 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. The multi-purpose glue of elastomer in the waistline is fixed today, and glue uses too much or the method is improper has all influenced the comfort level of waistline, easily causes the waistline harder or the elastomer atress is uneven to cause and warp, influences user's use impression.
Patent No. CN201710135983.3 discloses a method for applying and fixing rubber band glue of pull-up pants with warp. The method 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; after all the glue in the elastic body in the waistline is fixed, the space for free expansion is reduced, the retraction is not natural, so that the flexibility and the air permeability of the waistline are reduced, and the use feeling of a user is influenced.
