Abstract

The invention relates to the field of disposable hygienic products, in particular to an elastic waistline non-woven fabric which comprises an upper-layer non-woven fabric, a lower-layer non-woven fabric and an elastic film. Fastening points are formed among the upper-layer non-woven fabric, the elastic film and the lower-layer non-woven fabric, a plurality of cutting areas are defined by the fastening points, and at least one cutting unit is arranged in each cutting area. The cutting units are formed through ultrasonic welding and cut the upper-layer non-woven fabric, the lower-layer non-woven fabric and the elastic film, when the upper-layer non-woven fabric and the lower-layer non-woven fabric are in a straight state, the cutting units form air holes in the elastic film, and the air holes are flat in a stretched state. The upper non-woven fabric layer and the lower non-woven fabric layer are bonded at the cutting units, ventilation through holes are formed in the middle of the bonding portion, and all the ventilation holes surround all the ventilation through holes. The technical problems that an existing elastic non-woven fabric is insufficient in air permeability, and good comfort cannot be achieved are solved. The invention further provides a production method of the elastic waistline non-woven fabric.

Description

Technical field [0001] The present invention relates to the field of disposable hygiene, and more particularly to an elastic waist nonwoven fabric and a production method thereof. Background technique [0002] At present, the application of elastic waist non-woven fabrics has more applications, especially in the field of disposable hygiene, has more applications, such as China Patent Application Number: CN201210380277.2 Combined elastic nonwoven fabric Structure and manufacturing method, the composite elastic nonwoven fabric comprises an elastic fabric layer and a non-woven layer. The non-woven layer is integrated with the elastic fabric layer. And the composite elastic nonwoven fabrication method includes providing an elastic fabric layer; a non-woven layer is integrated with the elastic fabric layer; hot pressing the non-woven layer is flat to the elastic fabric layer; and cool the nonwoven layer and the elastic fabric Floor. Based on the composite elastic nonwoven fabric struc...
