Description

An easy-tear pants type diaper

technical field

The utility model relates to the field of sanitary products, in particular to an easy-to-tear pants type paper diaper.

Background technique

At present, most diapers are usually made of non-woven fabrics, toilet paper, fluff pulp, polymer water-absorbing resin, PE film and rubber bands, etc., all of which contain a waistband binding part and an adsorption part, which are not easy to wrap and bind at the same time. Give way. However, the diaper in the prior art adopts a notch-type design in the waist part, which reduces the connection and bonding strength and is easy to tear, and the communication openings formed by the notch make the diaper better air permeability. Although this design increases the air permeability, the loop-waist restraint part is directly welded and pressed by a hot pressing technology, and is divided into two parts, which makes the waist of the diaper more difficult to tear, resulting in the need to replace the diaper. A lot of force to tear the waistline will cause some inconvenience when replacing it, and it will also be easily contaminated with urine and excrement when it is torn off.

Because diapers are disposable products, in order to improve the usage rate of diapers, most of the product designs highlight the absorbency, skin-friendly and anti-side leakage of diapers. In order to prevent side leakage, the material that wraps and binds is also reinforced, which causes trouble in changing diapers every time, and the material that is too heavy will also cause the skin to be hot and breathless, which will cause skin diseases or bacterial growth. At present, the waist of most diapers is fixed by a hot pressing or ultrasonic welding, so that the elastic band of the waist is directly pressed on the diaper. It takes a lot of strength to tear it off, and it is very inconvenient to replace it. It is also relatively troublesome.
