Problems solved by technology

like figure 1 As shown, both sides of the diaper body 1' are provided with a set of leg elastics 2', and each set of leg elastics 2' is composed of a plurality of elastic bands arranged side by side at intervals, and an elastic band is formed between two adjacent elastic bands. The tendon channel, at the front waist area 31' and the back waist area 32', since there is no obstruction, when lying flat or prone, urine can easily flow to the front waist area 31' or the back waist area along the elastic channel At 32', there may be a risk of front and rear side leakage, and the appearance of the entire piece is flawed and not beautiful

Embodiment Construction

[0016] The present invention will now be further described with reference to the drawings and specific embodiments.

[0017] reference figure 2 , image 3 , Figure 4 , This embodiment provides a process for sealing the elastic channel of the leg of diaper, including the following steps:

[0018] In the first step, the bottom non-woven fabric and the leg elastics 2 are sprayed separately. When the leg elastics are sprayed, they are not sprayed on the composite area of ​​the front waist area 31 and the back waist area 32, and then input anti-sticking Transition roller, at this time the leg elastic is bonded to the bottom non-woven fabric;

[0019] In the second step, the waterproof membrane is sprayed with glue, and the bonded bottom non-woven fabric and leg elastics are bonded to the waterproof membrane by rolling;

[0020] In the third step, the diaper body 1 that has been bonded is then heat-pressed by a hot pressing device to heat-press the leg elastics 2 at the front waist area ...

Abstract

The invention relates to the field of disposable sanitary products, in particular to an edge sealing technology for a diaper leg rubber band channel.The edge sealing technology includes the following steps that 1, glue is sprayed to bottom layer non-woven fabric and a leg rubber band, then the bottom layer non-woven fabric and the leg rubber band are input into an anti-sticking transitional roller, and at the moment, the leg rubber band and the bottom layer non-woven fabric are bonded; 2, glue is sprayed to a waterproof film, the bonded bottom layer non-woven fabric and the leg rubber band are bonded with the waterproof film in a rolling mode; 3, hot press is conducted through a hot press device, the portions, located in the front waist region and the rear waist region, of the leg rubber band are treated in a hot press mode to be cut into multiple segments, and multiple blocking regions at intervals are formed on the portions, located in the front waist region and the rear waist region, of the leg rubber band in a hot press mode.

Description

Technical field [0001] The invention relates to the field of disposable sanitary products, in particular to a process for sealing the elastic channel of the leg of diaper. Background technique [0002] At present, in the structure of diapers, the leg elastics are glued between the bottom non-woven fabric and the bottom film. The leg elastics are only sprayed and fixed in the middle of the diaper, and the two sides do not need to be sprayed to fix. There will be elastic channels at the beginning and end of the pants structure. Such as figure 1 As shown, both sides of the diaper body 1'are provided with a set of leg elastics 2'. Each set of leg elastics 2'is composed of a plurality of elastics arranged side by side and spaced apart, forming an elastic between two adjacent elastics. Tendon channel, at the front waist area 31' and the back waist area 32', because there is no obstruction, when lying or prone, urine can easily flow along the elastic channel to the front waist area 31'...
