Description
Technical field
The present invention relates to a kind of hygienic article, especially relate to a kind of compound core body that is used for hygienic article such as the paper napkin, diaper, sanitary towel, protective pad, mattress.
Background technology
The existing compound core body that is used for the paper napkin, diaper, sanitary towel, protective pad, mattress etc. generally is made up of the following shortcoming of ubiquity dust-free paper top layer, dust-free paper bottom and bulk non-woven fabrics intermediate layer: adopt dust-free paper to need timber resources, not environmental protection; Generally all adopt adhesive to be connected between bulk non-woven fabrics intermediate layer and dust-free paper top layer and the dust-free paper bottom, not only manufacturing cost is higher, and the surface of dust-free paper top layer, dust-free paper bottom is bright finish, and absorption speed is slower.
Publication number is that the application for a patent for invention of CN1658810 discloses a kind of multilamellar absorbent cores, and this absorbent cores contains synthetic fibers, to improve the liquid transfer performance of obtained absorbent article.The innermost layer of absorbent cores and/or the synthetic fibers in the intermediate layer have especially improved the rewetting performance of absorbing products.Said absorbent cores can join in many absorbent articles, comprises diaper, feminine hygiene and incontinence pad.
Publication number is that the application for a patent for invention of CN1649554 discloses a kind of disposable absorbent article such as sanitary towel, panty liners, baby diaper, adult incontinence product and antiperspirant pad.Be arranged in the absorbent article that its lip-deep appointment towards the wearer is used for the zone of liquid deposition and have a monolayer top flat, between the operating period of goods absorbed liquid is being positioned on this top flat.Absorbent article also comprises the egative film on formation liquid obscures surface and the one absorbent cores between top flat and egative film.Said one core has improved the liquid handling ability of absorbent article and has strengthened the screening effect of goods, promptly hides the ability of the spot that causes owing to the liquid that absorbs.These goods for the urine that is used to absorb high color intensity such as menstrual fluid or old man are especially useful.
Publication number is that the application for a patent for invention of CN101797201A discloses a kind of polymer compound core body and preparation method thereof, relates to a kind of polymer compound core body.A kind of paper napkin and diaper of being mainly used in is provided, can not realize sticking together, do not rupture, the polymer compound core body of not delamination and preparation method thereof.Polymer compound core body is provided with dust-free paper top layer, dust-free paper bottom and bulk nonwoven layer; Bulk nonwoven layer is located between dust-free paper top layer and the dust-free paper bottom and with dust-free paper top layer and dust-free paper layer glue stick and is gluedd joint, and evenly oozing in the bulk nonwoven layer has water-absorbing resin.Urine can infiltrate in the polymer compound core body quick and completely; The dust-free paper top layer of compound core body can effectively suck urine; The hydroscopic high-molecular resin layer of polymer compound core body can effectively absorb the storage urine, and bulk nonwoven layer can make urine fast toward the infiltration of bottom direction, so water absorption is big; And can make surface layer keep making human body comfortable than drying regime
Summary of the invention
The purpose of this invention is to provide that a kind of feature of environmental protection is good, absorption speed is fast, the lower-cost compound core body that is used for hygienic article.
Said hygienic article mainly refers to hygienic article such as the paper napkin, diaper, sanitary towel, protective pad, mattress.
First technical scheme of the present invention is: the intermediate layer of mixing that is provided with non-woven fabrics top layer, bottom layer of non-woven fabrics and wood pulp cellulose and hydroscopic high-molecular resin; Mix the intermediate layer and be with non-woven fabrics top layer and bottom layer of non-woven fabrics that hot pressing is compound to be connected, the surface of non-woven fabrics top layer and bottom layer of non-woven fabrics all has embossing.
Second technical scheme of the present invention is: the intermediate layer of mixing that is provided with non-woven fabrics top layer, bottom layer of non-woven fabrics and wood pulp cellulose and hydroscopic high-molecular resin; Mix intermediate layer and non-woven fabrics top layer and bottom layer of non-woven fabrics and be connected through adhesive and through hot pressing is compound, the surface of non-woven fabrics top layer and bottom layer of non-woven fabrics all has embossing.
The 3rd technical scheme of the present invention is: the intermediate layer of mixing that is provided with non-woven fabrics top layer, bottom layer of non-woven fabrics and wood pulp cellulose and hydroscopic high-molecular resin; Mix intermediate layer and non-woven fabrics top layer and bottom layer of non-woven fabrics and be connected through adhesive is compound, the surface of non-woven fabrics top layer and bottom layer of non-woven fabrics all has embossing.
Embossing can be the concave point array described in first technical scheme, second technical scheme and the 3rd technical scheme.
In wood pulp cellulose described in first technical scheme, second technical scheme and the 3rd technical scheme and the blended intermediate layer of hydroscopic high-molecular resin (SAP); Press mass ratio; Wood pulp cellulose: hydroscopic high-molecular resin can be 1: (0.5～6); Press mass ratio, wood pulp cellulose: hydroscopic high-molecular resin is preferably 1: (1～3).
Compare with prior art, the present invention has following outstanding advantage:
Because of the present invention first, second all adopts non-woven fabrics top layer and bottom layer of non-woven fabrics with the 3rd technical scheme; The surface of non-woven fabrics top layer and bottom layer of non-woven fabrics all has embossing, can save timber resources like this, and the feature of environmental protection is good; And can absorb water fast; Urine can be infiltrated in the intermediate layer by the non-woven fabrics top layer fast, and the non-woven fabrics top layer can be very fast dry, makes human body comfortable.The present invention can protect better that baby and women's is healthy.Be connected because the intermediate layer described in first technical scheme is that hot pressing is compound with non-woven fabrics top layer and bottom layer of non-woven fabrics, can avoid adopting adhesive to connect, reduce manufacturing cost.
