Problems solved by technology
However, the unsaturated carboxylic acid polymer compound is used as the binder in this sheet, so there are problems that the remaining monomers during polymerization can irritate the skin, and because it is an unsaturated compound, it will change color during long-term storage.
[0012] On the other hand, the above-mentioned absorbent articles that can be discarded in flush toilets are accompanied by other significant problems: that is, problems related to the decomposition of materials flowing out of flush toilets
In addition, the materials described in the above-mentioned patent publications are also water destructive, but not biodegradable, so after being flushed into the toilet, they will still remain at the final disposal site without decomposing

[0212] Example [Preparation of water-destructive, biodegradable sheet-like substrate]
[0213] Disperse 20 parts of 0.6d×7mm Rayon fiber and 80 parts of unbeaten softwood pulp (NBKP) with a pulper, add about 50ppm of binder PEO, form it into a sheet with an inclined short-wire paper machine, and wet-form it into 30g / m 2 After dehydration, use a porous nozzle with a diameter of 0.01mmφ on the open drum to 2060kPa (20kgf / cm 2 ) of high-pressure water flow for pre-interweaving, further use 5980 kPa (60kgf / cm 2 ) high-pressure water flow for interweaving and drying as a base material. Although the nonwoven is stable when dry up to about 200% wetness, it decomposes heavily in large excesses of water.
[0214] The non-woven fabric is put into such as Figure 23 When it is in the stirring tank 223 which is mechanically stirred by the stirrers 223 and 224 shown, it is dispersed after stirring for about 30 seconds without maintaining the original shape.

Abstract
The absorbent article of the present invention is composed of a washable daily wear part covering a part of the body, a wearable and removable absorbent function part (disposable absorbent body) combined with the daily wear part, and the daily wear part which can be worn and removed. part and the combined part of the absorbing function part constitutes. Furthermore, at least a part of the absorbing portion is made of a water-destructive, biodegradable, or both water-destructive and biodegradable material.
Description
technical field [0001] The present invention relates to absorbent articles having a disposable absorbent body. Background technique [0002] In previous diapers, the whole diaper was tied tightly to the wearer's body to prevent it from not being close to the body or drooping, so that the wearer mostly had an uncomfortable tightening feeling. In addition, in the case of disposable diapers, the outer cover material, straps, side pads, etc. that do not affect the absorption of excreta are discarded as garbage together with the body part that involves disposable absorption of excrement. It has also become a social problem. [0003] As a method for fixing the absorbent body for absorbing excrement on the wearer's body, a structure in which an additional absorbent pad is held by a support member combined with a stretchable waist belt and a fastening strap (strap) is proposed (see JP-A 57-143502), plans such as keeping the absorbent pad on the wearer's body with fastening clips. ...
