Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabrics, in particular to a composite non-woven fabric and a diaper waist patch using the non-woven fabric. Background Art

[0002] Diapers, also known as wet diapers, have strong water absorption, can prevent excrement from leaking out, are easy to change, can prevent the lower body from getting wet, and are composed of multiple different functional layers. Existing adhesive diapers need to be fixed with waist stickers. Waist stickers are usually made of Velcro. When the waist stickers are torn, they often make a loud noise, or even harsh. This situation will not only stimulate the baby's hearing, but also wake up the sleeping baby and make him cry. The edge of the Velcro may scratch the baby's skin when putting on and taking off. In addition, the existing waist stickers are generally fixed to the main body of the diaper by hot melt glue or stitching, and the process is complicated. Therefore, it is necessary to study a composite non-woven fabric that can be cut into strips according to the required length as a diaper waist sticker to solve the problems of the existing waist stickers, such as loud noise, possible scratching of the skin by the edges, and complicated connection process.
