Embodiment Construction

[0037] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0038] refer to Figure 1 to Figure 3 , this embodiment provides a pull-up trousers, including a base material 1 and an absorbing body arranged on the base material 1, the two ends of the base material 1 in the longitudinal direction are respectively provided with a front waistline and a back waistline, the front waistline The two sides of the back waistline are respectively bonded to form a ring-shaped elastic waistline. The bonded base material 1 and the absorbent body form a front sheet 3 and a back sheet 4, and the absorbent body includes an absorbent core 21, a The leak-proof baffles on both sides of the absorbent core 21 include two or more baffle material layers 221 stacked on top of each other, and leakage-proof rubber bands 222 sandwiched between the two baffle material layers 221. , one side in the width direction of the leak-proof rib i...

Abstract

The present invention relates to the field of disposable sanitary products, in particular to a pull-up trousers, comprising a base material and an absorbing body, wherein the absorbing body includes an absorbing core and a leak-proof rib, and the leak-proof rib includes a rib material layer, an anti-leak Leakage elastic band, the leak-proof rib is clamped between the absorbent core and the base material, and the free end of the leak-proof rib extends upward and then wraps on the upper end surface of the absorbent core to form a primary covering portion. Both ends of the covering part along the length direction are bonded to the absorbent core to form a primary bonding part, the middle part of the primary covering part is not bonded to the upper end surface of the absorbent core to form a three-dimensional protective part, and the absorbent core is formed along the length direction. The middle part is provided with two crease grooves, the depth of the crease groove is 1 / 5-1 / 2 of the depth of the absorption core, and the width of the crease groove is 1 / 2-4 of the width of the absorption core / 5. The invention solves the technical problems that the folds of the existing pull-up pants are unstable, the folds have a great influence on the absorbent core, and wrinkles are easily generated. A pull-up pants forming process based on the same inventive concept is also proposed.

Description

technical field [0001] The invention relates to the field of disposable sanitary products, in particular to a pull-up trousers and a molding process thereof. Background technique [0002] At present, in the production process of pull-up pants, it is often necessary to go through a folding process, which is a necessary process before the waistline of pull-up pants is welded, such as a pull-up pants disclosed in Chinese Patent Application No. CN201910633868.8 The manufacturing process includes the following steps: the first step, making an absorbent core; the second step, compounding the first non-woven fabric and the liquid-impermeable film to form a bottom layer material, and bonding the waist elastic band on the bottom layer material; In the first step, the absorbent core is compounded with the bottom layer material; in the fourth step, the second-way non-woven fabric is bonded to the three-dimensional guard, the guard elastic band, and the plane elastic band to form a surf...
