Problems solved by technology

[0002] Existing diapers are generally equipped with a bottom non-woven fabric and a surface non-woven fabric. At the same time, the length of the surface non-woven fabric is equal to the length of the diaper, the length of the bottom non-woven fabric is greater than the length of the diaper, and the surface non-woven fabric is arranged on the bottom layer. On non-woven fabrics, the amount of non-woven fabrics for diapers with this structure is large, and the upper and lower ends of the three-dimensional enclosure of traditional diapers are respectively connected to the positioning PE film and the water-absorbing body. This structure requires the bonding area of ​​the upper and lower end surfaces of the three-dimensional enclosure Large enough to prevent movement or detachment, which leads to the use of more materials for the three-dimensional enclosure and a large bonding area

The one-piece type paper diaper production process comprises a water absorption main body and an elastic waistline, the elastic waistline is provided with a front elastic waistline and a rear elastic waistline, the water absorption main body is arranged between the front elastic waistline and the rear elastic waistline, the water absorption main body is sequentially provided with a water absorption core body, a positioning PE film and a bottom layer non-woven fabric from top to bottom, the elastic waistline is sequentially provided with surface non-woven fabric, middle non-woven fabric and bottom-layer non-woven fabric from top to bottom, and three-dimensional guards are further arranged on the left side and the right side of the water absorption body.

Description

technical field [0001] The invention relates to a production process of one-piece paper diapers. Background technique [0002] Existing diapers are generally equipped with a bottom non-woven fabric and a surface non-woven fabric. At the same time, the length of the surface non-woven fabric is equal to the length of the diaper, the length of the bottom non-woven fabric is greater than the length of the diaper, and the surface non-woven fabric is set on the bottom layer. On non-woven fabrics, the amount of non-woven fabrics for diapers with this structure is large, and the upper and lower ends of the three-dimensional enclosure of traditional diapers are respectively connected to the positioning PE film and the water-absorbing body. This structure requires the bonding area of ​​the upper and lower end surfaces of the three-dimensional enclosure. It must be large enough so that it will not move or fall off, which leads to the use of more materials for the three-dimensional encl...
