Problems solved by technology

[0004] In view of such problems, the main object of the present invention is to solve such problems by fluffing the lower ends of the respective liquid-guiding channels extending through the liquid-permeable surface layer, and then thermally deforming the hairs so as to align with the liquid-absorbable surface. The upper surface of the inner core is tangled together

Embodiment Construction

[0020] refer to figure 1 According to the inventive method of the present invention, the menstrual belt manufactured comprises a liquid-permeable top sheet 2 provided with a plurality of liquid-guiding channels 6, a liquid-impermeable bottom layer 3 and a liquid-absorbent layer arranged between the two layers 2 and 3. The inner core 4. Parts of the skin 2 and the bottom layer 3 extend beyond the peripheral edge of the inner core 4 and they are joined together watertight along a joint line 5 .

[0021] Referring to Figure 2, the cover 2 is made of polyethylene film and contains a skin contact area 10 defined by a continuous upper surface 11 and liquid guiding channels 6, each of which contains side walls 6a and passes through The surface layer 2 extends from the skin contact area 11 toward the bottom of the non-skin contact area 12, and is intermittently arranged along the direction of the plane defined by the surface layer 2 (the X-Y direction of the surface layer). Each liq...

Abstract

A thermoplastic film destined to be used as a topsheet of body fluids absorbent padding is thermoformed under the effect of a differential pressure of fluid to provide this film with liquid guiding passages and jags on lower ends of the passages. The jags are further thermally deformed to be intertwined with individual fibers of a liquid-absorbent core of the padding and thereby to bond the topsheet integrally to the core.

Description

technical field [0001] The present invention relates to a method of making absorbent body fluid pads, and more particularly to a method of making absorbent body fluid pads such as catamenial pads, menstrual pads, incontinence pads, disposable diapers and the like. Background technique [0002] It is well known to manufacture bodily fluid-absorbent pads such as menstrual pads and convenience diapers by passing a liquid-permeable cover made of thermoplastic synthetic fibers or a plastic film and a liquid-absorbent core containing thermoplastic synthetic fibers through thermal heating. Embossing makes a complete combination of the two. For example, Japanese Laid-Open Utility Model Application No. 1982-139318 discloses a technology that the top sheet of the convenience diaper and at least one upper surface of the liquid-absorbent inner core should be provided with heat-fusibility, and they are bonded together of. According to this technology, when the convenient diaper is worn...
