[0002] Diapers are collectively referred to as paper diapers, paper pants and pull -up pants, wherein the pull -up pants are like underpants, adopt the same material and structure with the paper pants, but can be directly put on and taken off, and are more close -fitted and elastic than the paper pants, and are suitable for active infants who start to turn over, learn to crawl or walk. The pull -up pants are mainly composed of a front waist body, a crotch and a back waist body, wherein the front waist body and the back waist body are folded upwards and form the form of underpants with the crotch.

[0003] At present, the pull -up pants circulating and sold on the market are connected by using ultrasonic waves, hot pressing rollers or hot melt glue to joint the front waist body and the back waist body of the pull -up pants, so as to form the pant -type paper diaper which can be directly put on and taken off. Although the front waist body and the back waist body of the pull -up pants are connected very tightly, the connection between the front waist body and the back waist body inevitably becomes thick, which causes poor air permeability and softness, and the wearer feels uncomfortable after a long time, and often sweats. In addition, the waist circumference and leg circumference of different infants have significant differences, and the fixed pull -up pants with the front waist body and the back waist body are difficult to adapt to different infants, and even it is difficult to wear.
