Disclosure of Invention

Therefore, aiming at the above content, the invention provides a method for preparing a pants-type sanitary napkin, which solves the problems that the sanitary napkin prepared by the preparation method in the prior art has poor attaching effect, the legs are easy to leak laterally and the requirements of using in the day and at night can not be met.

In order to achieve the purpose, the invention is realized by the following technical scheme: a method for preparing a pants-type sanitary towel comprises the preparation of an outer clothing layer and the preparation of an absorber, wherein the absorber is defined to have a longitudinal direction along a length direction and a transverse direction along a width direction, the preparation of the absorber comprises the preparation of a main absorber, the preparation of a secondary absorber and the compounding of the main absorber and the secondary absorber, and the method comprises the following specific steps: 1) preparing a liquid-permeable top layer;

2) preparing an absorbent core;

3) preparing a liquid impermeable back sheet;

4) the liquid-permeable bottom layer, the absorption core and the liquid-impermeable bottom layer are compounded into a main absorption body in an online manner;

5) spraying a layer of glue on the bottom surfaces of the two transverse sides of the liquid-tight bottom layer, wherein the transverse line width of each side accounts for 1/10-1/5 of the transverse width of the liquid-tight bottom layer;

6) preparing a secondary absorber, and compounding the secondary absorber on the two transverse sides of the liquid-permeable surface layer on line and folding the secondary absorber downwards and inwards to be attached to the bottom surface of the liquid-impermeable bottom layer sprayed with glue; the auxiliary absorber is formed by wrapping high-molecular water-absorbing resin with non-woven fabric;

7) the surface of the auxiliary absorber on the two transverse sides of the liquid-permeable surface layer is provided with embossing grooves extending along the longitudinal direction, the embossing grooves penetrate from the surface of the auxiliary absorber to the absorption core of the main absorber, and the surface non-woven fabric of the auxiliary absorber positioned at the embossing grooves is fixedly connected with the liquid-impermeable bottom layer.

The further improvement is that: the transverse width of the secondary absorbent is 1/5-2/5 of the transverse width of the liquid-impermeable back sheet, and the width of the secondary absorbent folded downwards and inwards occupies 1/3-2/3 of the transverse width of the secondary absorbent.

The further improvement is that: the two side edges of the auxiliary absorber extending along the longitudinal direction are both arc-shaped.

The further improvement is that: the thickness of the downward and inward bent region of the secondary absorbent body is thinner than the thickness on both lateral sides of the liquid-impermeable back sheet.

By adopting the technical scheme, the invention has the beneficial effects that: the sanitary towel prepared by the preparation method of the pants-type sanitary towel comprises the main absorber and the auxiliary absorbers, wherein the auxiliary absorbers are arranged on the two transverse sides of the main absorber, and one part of the auxiliary absorbers is folded downwards and inwards and is attached to the bottom surface of the liquid-impermeable bottom layer.

Furthermore, the transverse width of the auxiliary absorber is 1/5-2/5 of the transverse width of the liquid-impermeable bottom layer, the downward and inward folded width accounts for 1/3-2/3 of the transverse width of the auxiliary absorber, the transverse width of the auxiliary absorber is reasonable in layout, and the part of the auxiliary absorber in the interval, which is in contact with the body, is small, so that the auxiliary absorber is free from a sharp feeling and is comfortable to use.

Furthermore, two side edges of the auxiliary absorber extending along the longitudinal direction are both arc-shaped, and the auxiliary absorber is more tightly attached to the body after being unfolded.

Furthermore, the thickness of the downward and inward bending region of the auxiliary absorber is thinner than that of the two transverse sides of the liquid-tight bottom layer, so that the contact part of the unfolded part of the auxiliary absorber and the body is thinner, the fitting effect is better, and the use comfort is improved.
