Embodiment Construction
[0035] Such as Figure 3-4 , a new type of sanitary product, comprising a front waistline 23, a rear waistline 22 and an absorbent body 20 erected between the two, the front waistline 23 and the back waistline 22 both include an outer waistline 4 and an inner waistline 1, and an outer waistline 4 and A number of rubber bands 2 are horizontally arranged between the inner waistline 1, and joints 24 without glue are arranged between the outer waistline 4, the elastic bands 2 and the inner waistline 1, and the joints 24 are arranged at intervals in the transverse and longitudinal directions. The front waistline 23, the elastic band 2 and the rear waistline 22 between adjacent joints 24 are in a non-joined state, the joints 24 are formed by ultrasonic welding, and the edges of the joints 30 are partially broken due to the vibration energy applied by ultrasonic waves to form vent holes;
[0036] The elastic band 2 is disconnected in the overlapping area of the absorber 20 , the fr...

The invention relates to the technical field of disposable sanitary article in particular to a novel sanitary product and a production device and process, a novel sanitary product, including front waistline, a back waist circumference and an absorbent body erected between the two. Both the front and rear waist circumferences include the outer and inner waist circumferences. A plurality of rubber bands are transversely arranged between the outer waistline and the inner waistline, and an adhesive-free composite joint part is arranged between the outer waistline and the inner waistline, and the joint part is spaced apart in the transverse and longitudinal directions, the front waistline, the rubber bands and the rear waistline between adjacent joint parts are in a non-joint state, and the outer edge of the joint part is provided with an air vent. As that rub band is in an open state in the overlapping region of the absorbent body, the front waist circumference and the rear waist circumference so that the overlap region is an inelastic region, the joint portion of the rubber band and the inner and outer waist circumference of the present invention is welded to each other by applying vibration energy by ultrasonic wave, so that an adhesive is not required, and air vent holes are generated, and the air permeability is good.
Description
technical field [0001] The invention relates to the technical field of disposable sanitary products, in particular to a novel sanitary product, production device and process. Background technique [0002] A method of providing a pair of such waist members and bridging an absorbent main body between the waist members is well known for pant-type articles such as pull-on diapers, hygiene underpants, and incontinence underpants. At present, the production method of elastic waistline is usually to combine inner and outer waistline non-woven fabrics with spray glue and stretched elastic. The process is simple, but the elastic is fixed between two layers of basic non-elastic fabric materials with adhesive. , This will make the formed elastic folds hard and not soft enough, and will make the air permeability and softness of the material worse, especially cause certain damage to the baby's skin, and reduce the comfort of use. In addition, the production method of combining rubber ba...
