Problems solved by technology

[0002] The waist part of existing diapers generally adopts the fixing form of spandex yarn to realize the fixing of different waist circumferences, but this elastic band fixing method will cause gaps between the spandex yarn and the outer layer of the diaper. A large amount of glue is required, otherwise, these gaps will produce a large number of wrinkles as the elastic band shrinks. These wrinkles will be pressed against the user's skin when the spandex shrinks, and will form wrinkle-like indentations in the long run. Redness and swelling may occur, which may cause itching due to stuffy heat, which may cause discomfort to the user

Abstract

The invention relates to a pressure-reducing waistline of paper diapers, and a manufacturing process of the pressure-reducing waistline. The pressure-reducing waistline comprises an elastic hot-melt adhesive layer, wherein the elastic hot-melt adhesive layer is of a long strip-shaped structure, the front and back surfaces of the elastic hot-melt adhesive layer are respectively provided with a first non-woven fabric layer and a second non-woven fabric layer, and the first non-woven fabric layer, the elastic hot-melt adhesive layer and the second non-woven fabric layer are in close fit in sequence in the form of surface-to-surface contact. The speed differential pressing process is used, so that the produced elastic hot-melt adhesive layer has better ductility and elasticity, and is in closefit with the first non-woven fabric layer and the second non-woven fabric layer in all directions of 360 degrees, the overall extension and contraction is ensured to be in surface-to-surface fit withthe skin of a user, a contact area is improved, a pressure of an elastic waistline on the waist is effectively relieved, and the comfort is brought to the user.

Description

technical field [0001] The invention belongs to the technical field of diapers, and in particular relates to a pressure-reducing waist circumference of diapers and a manufacturing process thereof. Background technique [0002] The waist part of existing diapers generally adopts the fixing form of spandex yarn to realize the fixing of different waist circumferences, but this elastic band fixing method will cause gaps between the spandex yarn and the outer layer of the diaper. A large amount of glue is required, otherwise, these gaps will produce a large number of wrinkles as the elastic band shrinks. These wrinkles will be pressed against the user's skin when the spandex shrinks, and will form wrinkle-like indentations in the long run. Redness and swelling may occur, which may cause itching due to stuffy heat, which may cause discomfort to the user. [0003] Therefore, a new type of processing technology is needed to produce a pressure-relief diaper waistline that can effect...
