Abstract
The invention provides composite paper which comprises one or more paper layers and one or more strengthening layers, wherein the paper layers and the strengthening layers are connected through combining patterns; the paper layers are not connected with each other; at least one surface of the composite paper is the paper layer; the strengthening layers are non-woven fabric or plastic films. According to the invention, as the strengthening layers achieve higher strength after being wetted, so that after the strengthening layers are composited with the paper layers, the composite paper has better wetting strength, and avoids the problems of cracks and paper scrap residues when being wetted; besides, at least one surface of the composite paper is the paper layer, so that after the composite paper is in contact with the human body, the comfort and safety of the human body are guaranteed.
Description
Technical field
The present invention relates to paper production field, particularly a kind of composite sheet.
Background technology
Along with the raising of expanding economy and people's living standard, the demand of people to paper for daily use and disposable sanitary articles gets more and more.
Paper for daily use refers to all kinds of health wiping paper usings for look after individual house, go out etc. uses, and comprises roll tissue, interfold toilet paper, Boxed facial tissue, pocket face-tissue, tissue, napkin paper, paper for kitchen, wet tissue, shoes cleaning paper, tissue etc.Because paper for daily use uses the native cellulose such as wood pulp, bamboo pulp as raw material, therefore compare natural environmental-protective, and use pleasant.But paper for daily use is under chance wet condition, and intensity is very low, usually at below 1.5N/15mm.This kind of paper for daily use usually breaks and leaves paper scrap when using, if will increase wet strength, needs to add a lot of chemical wet strength agent when papermaking, brings complete in security risk to consumer.
Common disposable sanitary articles, as wet tissue, sanitary napkin, paper diaper, protection pad etc., general use nonwoven fabric does surface layer, due to the large percentage of synthetic fiber or chemical fibre, natural texture is poor, and often remain the trace level chemical substances such as catalyst, reaction monomers, chemical finish, bring potential security risk to consumer.
Described in total upper, consumer wishes to use more comfortable, safety and the higher product of wet strength.

Detailed description of the invention
In order to understand the present invention further, below in conjunction with embodiment, the preferred embodiment of the invention is described, but should be appreciated that these describe just for further illustrating the features and advantages of the present invention, instead of limiting to the claimed invention.
The embodiment of the invention discloses a kind of composite sheet, comprise at least one deck ply of paper and at least one deck enhancement layer, described ply of paper and enhancement layer are by being connected in conjunction with line; Be not interconnected between described ply of paper;
Described composite sheet has at least a surface to be ply of paper;
Described enhancement layer is in nonwoven fabric or plastic sheeting.
In the present invention, described composite sheet comprises at least one deck ply of paper and at least one deck enhancement layer.Described ply of paper is preferably paper for daily use, and described enhancement layer is nonwoven fabric or plastic sheeting.Described nonwoven fabric is preferably hot-wind nonwoven cloth, spun-bonded non-woven fabrics, fabric hot rolled nonwoven fabrics, melt spraying non-woven fabrics or spunlace non-woven cloth.Described plastic sheeting is preferably polyethylene film, polyester film, polypropylene screen, polyacrylamide film or poly tetrafluoroethylene.Described enhancement layer still can keep good intensity after meeting water, thus the composite sheet that guarantee and paper obtain after checking is wet better strong.Preferably, described enhancement layer surface has plain weave, grid line, idea line or has circle, criss-cross, taper perforate., the present invention is not particularly limited for the shape in the hole on enhancement layer and size, can be the hole of various shape and size, is preferably circular, criss-cross or taper perforate.Enhancement layer with holes can increase the gas permeability of composite sheet, thus increases the comfort level of composite sheet.The thickness in monolayer of described enhancing is preferably less than 1mm, with convenient to be combined with paper and to ensure easy to prepare, use comfortable.
Described composite sheet can be two-layer, can be also multilayer, has at least a surface to be ply of paper, to ensure comfort level and the security of composite sheet.In certain embodiments, described composite sheet is double-layer structure, and comprises one deck ply of paper and one deck enhancement layer.In other embodiment, described composite sheet comprises one deck ply of paper and multilayer enhancement layer.Also have in some embodiments, described composite sheet comprises multilayer ply of paper and multilayer enhancement layer.When comprising multilayer ply of paper, non-conterminous between described ply of paper; When comprising multilayer enhancement layer, between enhancement layer can adjacent also can be non-conterminous, thus ensure composite sheet in conjunction with firm.Preferably, described ply of paper and enhancement layer are arranged alternately.In order to ensure that described composite sheet is prepared easy and easy to use, total number of plies of preferred described ply of paper and enhancement layer is less than 10 numbers of plies.The number of plies is excessive, and composite sheet is blocked up, is inconvenient to use; And the number of plies is more, preparation difficulty is larger.
By connecting in conjunction with line between described ply of paper and enhancement layer.Described be the position that ply of paper and enhancement layer combine in conjunction with line, and can be one side, also can be two-sided.Described can be various shape in conjunction with line, ensures that ply of paper and enhancement layer combine firmly.The present invention is not particularly limited the described shape in conjunction with line, any one shape preferably in linear, shaped form, oblique line shape, ellipse, circle, rhombus, flower shape and grid shape or the combination of various shape.
In the present invention, described composite sheet, through cutting, can directly use as products such as toilet paper, face tissue and cleansing tissues; Also may be used for wet tissue base material and substitute traditional non-woven cloth; The surface layer of sanitary napkin, protection pad or paper diaper can also be used for replace traditional nonwoven fabric.
The present invention is not particularly limited for the preparation method of described composite sheet, can be pressure sintering or supercritical ultrasonics technology.Described pressure sintering, comprises the following steps: ply of paper is become one group with enhancement layer mounted on top, pressure roller, by heating pressurization, is formed in conjunction with line, ply of paper and enhancement layer are linked together at ply of paper and enhancement layer surface.
Described supercritical ultrasonics technology, comprises the following steps: ply of paper and enhancement layer are stacked, and forms ultrasonic wave with the region that supersonic generator is needing to combine, and under ul-trasonic irradiation, ply of paper and the enhancement layer generation higher-order of oscillation and formed in conjunction with line, link together.
