Process and apparatus for producing apertured or non-apertured nonwoven fabric wherein fibrous web is introduced onto support means and treated with high velocity water streams jetted from above. The non-apertured nonwoven fabric may be produced by fiber entangling treatment on a smooth surfaced plate including a plurality of drainage holes as first support means or by further fiber entangling treatment performed on water impermeable second support means after the fiber entangling treatment performed on the first support means. The apertured nonwoven fabric may be produced by, after the fiber entangling treatment on the first support means, using, instead of the second support means, another second support means consisting of a smooth surfaced plate provided with a plurality of projections and drainage holes so that individual fibers of the fibrous web are deflected by water streams jetted from above the fibrous web aside towards zones of the surface defined by each pair of adjacent projections while entangling these individual fibers with each other.

A method for coating a dispersion slurry containing a solid SAP dispersed in a dispersion medium on a surface of a substrate sheet are provided. The method is characterized in that a first region and a second region are formed on the surface of the substrate sheet with a convex-and-concave pattern wherein the first region have the coating layer in thicker thickness and the second region have the coating layer in thinner thickness or does not scarcely have the coating layer, by means of positioning the rotating pattern roll over the substrate sheet via the cover film, of supplying the dispersion slurry between the substrate sheet and the cover film while rotating the rotating pattern roll, and of pushing the coating layer with the rotating pattern roll via the cover film, when the coating layer of the dispersion slurry is formed.

An absorbent product capable of preventing the absorbing rate from significantly lowering with the elapse of time, from the start of use to a final stage when the absorbing capacity of the product reaches a limit, is provided. The absorbent product has a very small re-wet amount. The absorbent product includes a liquid-impermeable surface sheet positioned on the upper side, a liquid-impermeable back sheet positioned on the lower side, and an absorber containing super absorbent polymer to absorb discharged liquid positioned between the surface sheet and the back sheet, wherein a flow passage is provided to allow a part or all of the discharged liquid supplied to the surface sheet to move to a side of the back sheet.

It is an object of the present invention to provide an absorbent article having an excellent utilization efficiency of an absorber. The object is attained by an absorbent article including: a leak preventer including a bottom surface part extending in a front-rear direction, and side parts raised to an upper side at both left and right sides of the bottom surface part; an absorber containing super absorbent polymer for absorbing a body fluid placed in an internal space formed by the bottom surface part and the side parts of the leak preventer in at least one layer; and a liquid guide unit placed in a front body part of the internal space, at a position where a flow of discharged urine directly collides with the liquid guide unit, for moving, when urine is discharged, the urine from the position where the urine has collided therewith to other positions.

A method for producing a microfibrillated cellulose, which comprises subjecting a slurry containing a pulp having a solids concentration of 1 to 6 wt % to the treatment with a disc refiner repeatedly ten times or more, to thereby prepare a microfibrillated cellulose having a number average fiber length or 0.2 mm or less and an amount of water hold of 10 mL/g or more, the amount representing the volume of water capable of being held by a unit weight of the cellulose fiber. The method allows the production of a microfibrillated cellulose having high quality with stability and with good efficiency.
摘要:
An absorbent easily rendered three-dimensional in the central region by water absorption is composed of a sheet-like absorbent having regions where a highly absorptive component is present and regions where it is absent, these presence and absence regions parallelly extending lengthwise of a sheet-like base material and alternating with each other, the sheet-like base material being turned back along a bending line in the highly absorptive component absence regions of the sheet-like absorbent, there being at least one band-like portion of multilayer construction where the highly absorptive component presence regions are superposed in a plurality of layers.

It is an object of the present invention to provide an absorbent article which does not cause discomfort to a wearer when worn, particularly after an absorber absorbs a body fluid to be swelled, and which is capable of receiving urine and feces separately. The object is attained by an absorbent article, including: a leak preventer having a sheet, and two bags provided separately on right and left of an upper side of the sheet, each of the two bags having an opening facing with each other; and an absorber having at least one layer and containing a super absorbent polymer and capable of absorbing a body fluid, provided in each of the two bags.
