Description

TECHNICAL FIELD The present invention relates to a napkin containing a nonwoven fabric and pulp.

○ Prior Art Known napkins are known in which a mesh sheet is attached to the body side for the purpose of improving the absorbability of body fluids and eliminating the adherence of body fluids to the wearer's body to improve the feeling of use.

Problems to be Solved by the Invention In the above-mentioned conventional technology, since the napkin to which the reticulated sheet is added requires the expensive reticulated sheet, there is a problem that the unit price of the product becomes high as a napkin of this kind of low-priced product. .

Means for Solving the Problem The present invention is a solution containing a heat-bonding non-woven fabric and a heat-bonding non-woven fabric in which a large number of uneven patterns are formed on the non-woven fabric side surface of a napkin on the non-woven fabric side surface by heat embossing. The absorbent pulp sheet is wrapped with the refined pulp into three folds in the width direction, and a waterproof sheet is bonded to the folded side to form a napkin.

Examples Examples will be described below based on examples shown in the drawings.

FIGS. 1 to 3 show a napkin having an uneven pattern formed on the surface thereof. A heat-adhesive non-woven fabric 1 is used to wrap a defibrated pulp 2 containing heat-sealing fibers, and the entire surface is heat-embossed. A large number of concavo-convex patterns 4 formed by (heating die) are provided. In addition, the nonwoven fabric 1 is formed by heating by heat embossing or by heat-sealing action by heating with hot air given in another step.
And pulp 2 are integrated by fusion and pulp 2
The parts other than the heat-sealing fibers are fixed to each other by the fusing action of the heat-sealing fibers.

The material of the non-woven fabric 1 enables heat sealing (heat bonding) such as a heat fusion type, an adhesive type (containing a hot melt adhesive), and a spunbond direct spinning type, and the pulp 2 is, in the embodiment, The structure contained (15% to 50%) heat-bonded fibers.

The present invention will be described with reference to FIGS.
Similar to the napkin shown in FIGS. 3 to 3, a large number of concavo-convex patterns 4 formed by heat embossing (heat pressing) are formed in the widthwise central portion of the nonwoven fabric 1, and the nonwoven fabric 1 and the pulp 2 are folded in three in the widthwise direction. And wrap the absorbent sheet (for example, tissue paper) 5 in three folded pulp 2,
A waterproof sheet (for example, on the side opposite to the uneven pattern 4)
The PE sheet) 3 is adhered to form a napkin.

In the above-described embodiment, the uneven pattern 4 formed by heat embossing causes the nonwoven fabric 1 and the pulp 2 to have a recess Q as shown in FIG. Then, the fibers outside the heat-sealing fibers in the pulp 2 are also fixed via the heat-sealing fibers P by the fusion of the heat-sealing fibers in the pulp 2.

Therefore, the presence of the concavo-convex pattern 4 and the fusion-bonding fibers P prevents collapse of the pulp mold. In addition, the uneven pattern 4 increases the surface area of the napkin to enhance the absorbability and diffusibility.

Next, with reference to FIG. 8, an embodiment of the napkin manufacturing method of the present invention will be described.

Referring to FIG. 8, the defibrated pulp 2 is fed from the defibrating pulp feeding device B to the upper surface of the non-woven fabric 1 fed from the non-woven fabric feeding roll A, and the non-woven fabric 1 and the defibrated pulp 2 are fed. The state of overlapping.

With the folding device C, the nonwoven fabric 1 is folded in three,
Wrap the defibrated heat-fusible pulp 2.

Next, hot air from the hot air supply device D is supplied to the nonwoven fabric 1 and the defibrated pulp 2 from above. In the example
Hot air at 180 ° C was applied for 2 seconds. The pulp 2 and the non-woven fabric 1 are adhered and integrated by the fusing action of the heat-fusible fibers in the pulp 2 by the hot air and the heat-adhesive action of the heat-adhesive non-woven fabric 1, and the heat-fusion fiber of the pulp 2 is also integrated. The other parts are bonded to each other by the fusing action of the heat-bonding fibers and their shapes are fixed.

Next, the concavo-convex pattern 4 is formed on the non-woven fabric 1 and the pulp 2 on the non-woven fabric 1 side by the heat embossing device E. The size and depth of the concavo-convex pattern on the embossing roll side (lower side in the embodiment) of the heat embossing rolls e and e ′ are selected by selecting the position, shape and distribution of the embossing pattern formed on the surface of the embossing roll. The position is arbitrary.

It is also possible to omit the hot air supply device D by substituting the heating with the hot air from the hot air supply device D by the heating action of the heat embossing device E.

Tarpaulin supplied from the tarpaulin supply roll F (P.
The E sheet) 3 is supplied to the upper surface of the pulp 2 fused and fixed as described above.

The end heat seal device G including the heat embossing roller g heats the peripheral portion of the napkin while forming irregularities, and the waterproof sheet 3 is thermally bonded to the nonwoven fabric 1 with the pulp 2 interposed therebetween to form the end seal portion 6. (Note that when a conventional halp is used, the non-woven fabric and the waterproof sheet cannot be end-sealed with the pulp intervening, so the pulp is not intermittently present in the end-sealed portion. However, since the heat-fusible pulp is used, it is possible to end seal between the nonwoven fabric and the waterproof sheet while the pulp is continuously supplied).

After that, with the cutting device H, the nonwoven fabric 1 is formed into a desired shape,
The napkin N is completed by cutting together with the pulp 2 and the waterproof sheet 3.

Further, in the production of the napkin of the present invention, a step of folding the pulp and the non-woven fabric into three in the width direction and a step of supplying absorbent paper are added.

Effect of the Invention The invention of the present application is that the surface area of the napkin is increased by forming a large number of recesses on the body side of the napkin due to the large number of concavo-convex patterns formed by heat embossing on the non-woven fabric and pulp, thereby increasing the absorbency and absorption rate. Is improved. Further, there is an effect that the napkin does not lose its shape because the nonwoven fabric and the pulp are fused and fixed by heat embossing and the nonwoven fabric is heat-adhered and fixed.

Further, according to the present invention, the diffusibility and absorption of body fluid can be enhanced by wrapping the absorbent paper with pulp.
