This water-soluble multilayer wiper sheet has a water soluble surface sheet made of the water distributing fiber and a water soluble back surface sheet. The surface sheet is provided with multiple open hole parts passing through the layers, and the open hole parts are sealed in an interface part between the surface sheet and the back surface sheet. When using the surface sheet as a wiper surface, the relatively large waste and dust is caught by the open hole parts. Passing through of the caught waste and dust to the back surface of the wiper sheet is prevented. This wiper sheet has the sufficient strength for use, and it can be thrown away into a toilet after using it.
Description
Technical field
The present invention relates to the intensity height, and by the easy structural hydrolyzed rubbing piece that disperses of current.More particularly, the present invention relates to the structural hydrolyzed rubbing piece of the good sandwich construction of dust capture ability.
Background technology
In order to clean or stroke examination skin, people adopt the disposable rubbing piece that is made of paper or nonwoven.In such rubbing piece, if can after the use it washed out in the lavatory same as before, then be easily, thus, people's exploitation has water-disintegrable rubbing piece.But, smear the intensity of wiping operation if want to have to bear, then water-disintegrable reduction, when washing out in the lavatory, it disperses in purification tank and need take a long time, or with the rhone obstruction in lavatory etc.
In addition, most cases is that rubbing piece comprises the dirt of moisture in the cleaning around the lavatory.So, even above-mentioned must have and comprise still non-destructive intensity under the state of small amount of moisture.In addition, also have following situation, promptly from the aspect of easy or operation effectiveness, rubbing piece is to pack under by moistening in advance state such as cleaning solution to sell.So water-disintegrable rubbing piece must have to bear smears enough dry tenacities of wiping operation, and is preferably soaking the enough moistening intensity of bearing the wiping operation under the state that contains moisture, when being in addition to wash out in the lavatory, its easy hydrolysis.
As water-disintegrable rubbing piece, in the flat 3-113098 document of TOHKEMY a kind of water-disintegrable cleaning article is disclosed.In this cleaning article, stacked on the untapped water-disintegrable fibrolaminar two sides of bonding agent by the bonding water-disintegrable fibrage of water soluble adhesive, it is carried out embossing handle.But, in this cleaning article, be difficult to catch bigger dust or dust, in addition, slide easily and be difficult to use in the surface.
Summary of the invention
The present invention proposes for solving above-mentioned existing problem, the object of the present invention is to provide water-disintegrable and good strength, and the good structural hydrolyzed rubbing piece of the capture ability of dust.
The present invention relates to following structural hydrolyzed rubbing piece, it is the sheet of sandwich construction, this sheet comprises the water-disintegrable outer coversheet that is formed by water-dispersible fiber, and the water-disintegrable internal surface layer that overlaps with above-mentioned outer coversheet, it is characterized in that on above-mentioned outer coversheet, the a plurality of aperture portion that connect layer are set, and above-mentioned aperture portion is the boundary portion place of surface layer and internal surface layer outside, is stopped up by internal surface layer.
At this moment, best above-mentioned internal surface layer is formed by water-dispersible fiber, and is provided with a plurality of aperture portion that connect layer, in above-mentioned boundary portion, the aperture portion of above-mentioned outer coversheet is stopped up by internal surface layer, and the aperture portion of above-mentioned internal surface layer is stopped up by outer coversheet, and two surfaces of the sheet of sandwich construction form the wiping face of smearing.
Perhaps, the present invention relates to following structural hydrolyzed rubbing piece, it is the sheet of sandwich construction, this sheet comprises water-disintegrable outer coversheet and the internal surface layer that is formed by water-dispersible fiber, and between above-mentioned outer coversheet and internal surface layer, the water-disintegrable intermediate layer that overlaps with these layers, it is characterized in that on above-mentioned outer coversheet and internal surface layer, the a plurality of aperture portion that connect layer are set, the aperture portion of above-mentioned outer coversheet and internal surface layer is at the boundary portion place in they and intermediate layer, stopped up by the intermediate layer, two surfaces of the sheet of sandwich construction form the wiping face of smearing.
Because structural hydrolyzed rubbing piece of the present invention has sandwich construction, so can have higher intensity,, it is washed out in lavatory etc. if after use, it is soaked in a large amount of water, then the decomposition of layer shape.In addition, owing to, be provided with aperture portion,, hold it in the peristome of sheet so catch bigger dust or dust easily as the sheet outside of smearing wiping face.In addition, because above-mentioned aperture portion does not penetrate into the inner face of sheet, so the dust of being caught is not gone to the inboard of sheet, hand or the keeper that can not make dirty and hold sheet.

The specific embodiment
With reference to the accompanying drawings, present invention is described.Fig. 1 (A) is the perspective view of rubbing piece of the present invention, and Fig. 1 (B) is for being described more specifically the amplification key diagram of structure of rubbing piece, and Fig. 2 be the cutaway view of the part amplification of rubbing piece of the present invention shown in Figure 1.
The rubbing piece 10 of Fig. 1 (A) forms like this, and the outer coversheet 1 that will have aperture portion 3 respectively and the internal surface layer 2 that does not have aperture portion are made as layer independently, then they are overlapped.On the whole surface of surface layer 1, offer a plurality of aperture portion 3 that connect this outer coversheet 1 outside.When cleaning, the outside 1s with outer coversheet 1 side of aperture portion 3 constitutes the wiping face of smearing.If the STRUCTURE DECOMPOSITION of this rubbing piece 10 is amplified, then its shown in Fig. 1 (B) like that.That is, as shown in Figure 2, the outer coversheet 1 that will have aperture portion 3 overlaps with the internal surface layer 2 that does not have aperture portion, by the internal surface layer 2 that does not have aperture portion, the aperture portion in the outer coversheet 1 is stopped up, and in rubbing piece 10, peristome 3 does not connect along thickness direction.
The rubbing piece 10 of such sandwich construction can be smeared the bigger dust of wiping by being presented in as the aperture portion 3 on the outside 1s that smears wiping face.In addition, the dust through smearing wiping remains on the inside of peristome 3, does not run out of the inner face of internal surface layer 2.Therefore, even when being to clean, keep by hand or mop etc. still can under the situation of hand or mop etc. not being made dirty, compatibly using under the situation of inner face of internal surface layer 2.In addition, rubbing piece 10 has water-disintegrable.So if after being used to smear the wiping operation, it is washed out in the lavatory, then each layer separates, and easily layer shape decomposed, and realizes hydrolysis.
Preferably outer coversheet 1 has the fiber of good dispersiveness by relative glassware for drinking water, and promptly the fiber of water dispersible forms.The implication of the dispersiveness of alleged here relative water is with water-disintegrable identical, and it refers to scatter between the fiber, with the character of layer shape deterioration by contacting with a large amount of water.Best, these fibers also are biodegradable fiber.If the employing biodegradable fiber, even then discarding under the situation of occurring in nature, it still can decompose.From water-disintegrable and intensity balance aspect, preferably the fibre length of fiber is in the scope of 1～10mm.The fibre length of alleged fiber refers to average fiber length among the present invention.
As fiber, can adopt at least a fiber of from the group of natural fiber and chemical fibre formation, selecting.As natural fiber, exemplify coniferous tree paper pulp (pulp) or expand the paper pulp (pulp), abaca, staple slurry etc. of leaf tree paper pulp (pulp) etc.These natural fibers are Biodegradables.In these fibers, preferably coniferous tree bleached kraft pulp or expansion leaf are set in the bleached kraft pulp, and particularly water dispersible is good.In addition, synthetic pulp that exemplify the synthetic fibers, Biodegradable synthetic fibers of chemical fibre as the staple fibre of regenerated fiber or fibrillation staple fibre etc., polypropylene, polyvinyl alcohol, polyester, polyacrylonitrile etc., forms by polyethylene etc. etc.In them, staple fibre is Biodegradable preferably.In addition, also can adopt the biodegradable fiber of aliphatic polyester, polyvinyl alcohol and the collagen etc. of PLA, polycaprolactone, polybutene succinate etc.In addition, obviously,,, then still can adopt if having water dispersible even be above-mentioned fiber fiber in addition.
In above-mentioned fiber, preferably adopt the fibrillation staple fibre.If contain the fibrillation staple fibre in the surface layer 1 outside, because the microfibre of fibrillation staple fibre extension is caught relatively, keep trickle dust or dust, so the effect increase is wiped in smearing of sheet.When in aperture portion 3, when catching bigger dust,, prevent that bigger dust from coming off from rubbing piece 10 by microfibre.So the floating capacitation power of the dust of rubbing piece 10 rises significantly.In addition, owing to mainly contact with other surface from the microfibre of fibrillation staple fibre extension, so the frictional force that whole rubbing piece directly is subjected to reduces.So the frictional strength of the outside of structural hydrolyzed rubbing piece of the present invention is higher.In addition, microfibre in the fibrillation staple fibre and other fiber, or the microfibre in other the fiber is intertwined, and in addition, forms hydrogen bond, so can obtain higher intensity.Also have, if supply with a large amount of water, the mutual winding between the then above-mentioned microfibre is thrown off, or hydrogen bond is cut off, and realizes hydrolysis easily.
The fibrillation staple fibre refers to the fiber that forms carry out fibrillation to handle subtly as the surface of the staple fibre of regenerated cellulose, be its such formation, diameter is that the microfibre of sub-micron (submicron) and the main part of fiber (fibrillation staple fibre) are peeled off, and extend on the surface of the main part of the relative fiber of microfibre.The surface of common regenerated cellulose is level and smooth, and is relative therewith, and handle through fibrillation on the surface of fibrillation staple fibre, has different structures.
The fibrillation staple fibre can be by for example, when the suction of staple fibre is moistening, applies mechanical force and obtain, has the blender of passing through, in water, staple fibre is forced stirring method, adopt pulper or refiner or agitator etc., the method for its processing of pulling an oar (thick shape making beating).The fibrillation staple fibre can be following type, the fiber of the type forms like this, promptly the staple fibre to the koplon handled through wet type spinning etc. carries out acid treatment, then, apply mechanical force, it is carried out fibrillation handle, perhaps above-mentioned fibrillation staple fibre is a following type etc., it is that the staple fibre of handling by the solvent spinning is applied mechanical force, then it is carried out fibrillation and handles.But, also can adopt the common regenerated cellulose of handling through the wet type spinning, form the fibrillation staple fibre.
Distribute (Mass Distribution) if measure the weight average fiber length of the fibre length of fibrillation staple fibre,, produce two peak values then mainly according to distributive sorting.The peak value that fibre length is short, be that fibre length is less than or equal to the main part that concrete part beyond the ratio that 1mm occupies is mainly the fibrillation staple fibre, in above-mentioned remaining concrete part, also comprise and carry out the fibrillation processing and the microfibre of elongation, or cut off and the staple fibre of formation.The fibre length of main part itself is handled the fibre length that is shorter than before making beating is handled by making beating, because the existence of the microfibre that extends from the end of main part looks that it is long slightly.So, in the fibrillation staple fibre after making beating is handled, the quality of main part reaches the nominal fibre length of the staple fibre of fibre length before making beating is handled of part of peak value itself in the scope of ± 0.5mm, specifically ,-0.3～+ scope of 0.1mm in.
Fibrillation staple fibre of the present invention can refer in particular in the manner described above, mainly comprise the peak value of fibre length of the main part of fibrillation staple fibre, and as the type of the peak value of the fibre length of the microfibre that has carried out the part that fibrillation handles.In addition, in the fiber that forms in the fast beating processing of staple fibre having been carried out adopt usually in order to pull an oar, the fiber that will all be broken into fine shape and have pristine fibre length is in almost non-existent state, and this is different with the alleged fibrillation staple fibre of the present invention.
According to the present invention, as the fibrillation staple fibre, the type that is fit to is: the occasion in the scope of fibre length at 3～5mm of the staple fibre before making beating is handled (in the scope of fibre length at 2.5～4.5mm of the peak value of the Mass Distribution of the aforementioned body part after making beating is handled), if degree of blending is less than 400cc, then the length microfibre that is less than or equal to 1mm accounts for 0.5～15 quality % of deadweight (quality of the integral body of fibrillation staple fibre).But, be limited to 8 quality % on the occasion by the making beating of pulper or refiner.In addition, the occasion in the scope of degree of blending at 400～700cc, the length microfibre that is less than or equal to 1mm accounts for 0.1～5 quality % of deadweight.Yet, on the occasion of pulling an oar, be limited to 3% quality by pulper or refiner.In addition, pulling an oar by pulper or refiner, degree of blending is limited to 0.2 quality % down in the occasion of 400～600cc.
In addition, the occasion (fibre length of the peak value of the Mass Distribution of main part making beating handle after the scope of 4.5～7.5mm in) of the fibre length of the staple fibre before making beating is handled in the scope of 5～7mm, if degree of blending is less than 400cc, then the length microfibre that is less than or equal to 1mm accounts for 8～65 quality % of deadweight.But, also have following situation, promptly on the occasion of pulling an oar, be limited to 30% quality by pulper or refiner, be limited to 5 quality % down.In addition, if degree of blending in the scope of 400～700mm, then the length microfibre that is less than or equal to 1mm accounts for 0.3～50 quality % of deadweight.But, be limited to 20% quality on the occasion by the making beating of pulper or refiner.In addition, pulling an oar by pulper or refiner, degree of blending is limited to 2% quality down in the occasion of 400～600cc.
In addition, the degree of blending that is suitable for fibrillation staple fibre of the present invention is less than or equal to 700cc.This degree of blending can be adjusted by the time that making beating mechanism or making beating are handled, and along with the carrying out (numerical value of degree of blending diminishes) of making beating, increased than the ratio of the Mass Distribution of short fiber (comprising microfibre).If degree of blending is greater than 700cc, then the formation amount of microfibre is few, can not expect the effect of gaining in strength.In order to form an amount of microfibre, particularly preferably degree of blending is less than or equal to 600cc.In this occasion, the rising of the intensity of the rubbing piece that microfibre causes is more remarkable.Above-mentioned degree of blending especially preferably is less than or equal to 400cc.In addition, also can adopt degree of blending to be less than or equal to 200cc, particularly be less than or equal to 100cc (such as, 50cc or 0cc) the fibrillation staple fibre.
