Description

The laundry treatment compositions that has lamellar visual cues
The present invention relates to have the laundry treatment compositions of the lamellar visual cues (visual cues) that downcuts from film.
Background
Laundry treatment compositions comprises clean fabric and other Fabrid care composition, like fabric softener, special-purpose decontamination product etc.Said composition can present solids compsn (comprise washing powder, like the solid detergent form of sheet and bar) or forms of liquid compositions.
The known matrix band that in laundry treatment compositions, comprises.
GB2358403A proposes to use matrix band as the visual cues in the washing powder compsn.This film is colored water-soluble plastic.The mean particle size of sheet at least one dimension is obviously greater than the mean particle size that contrasts powder particle.Embodiment in this patented claim uses the circle or the star plate of 5 mm dias.The used circle and star, GB2358403A also discloses squares and triangles in these embodiment.Also disclose: trilateral, square, pentagon and hexagonal mixture; The mixture of numeral, the mixture of alphabetic(al) letter; And the mixture of the sun, the moon and star.
From film, cut out circle or star and stay the film waste material of high per-cent, they should recycling.This recycling is expensive and poor efficiency.In addition, if comprise sensitive composition in this film, possibly further limit recycling owing to the thermal treatment that under the situation of not destroying sensitive composition, can stand or the restriction of other processing to this film.
WO2006/079416 discloses the alternative shape of the sheet of function as visual cues.Embodiment in this application uses the visual cues of being processed by the Sudan Gum-arabic sheet.This Sudan Gum-arabic sign is erose and forms the random shape (having trilateral or " nail " shape outward appearance usually) with acute angle and make through a sheet of film is cut apart.Because the size of these shapes is at random, must screens them and divide with the level that obtains being suitable for.Suggestion is selected to pass through 1400 tm screen but is not divided through the level of 500 tm screen.If use this method of manufacture, nearly 30% the visual cues of processing needs recycling or discarded.In addition, we have found that the human consumer is to the visual cues not as regular shape of liking of randomly shaped visual cues.
WO2007/022229 discloses to the solid cleaning agent base-material, as mixing visible membranelle formed body in the soap bar.Except that visual contrast was provided, square film inclusion it is said influenced other organoleptic factors, like the sense of touch of this product.
EP 1319706 discloses liquid detergent composition, and solid polymer membrane is immersed in wherein.This spill sheet is regular shape preferably.In GB2358403A the disclosed shape, teddy bear shape visual cues is disclosed also.
Simple and complicated tiling design all is known.In this manual, tile or inlay with following meaning and use: a surface, especially plane, can be by these one or more formed bodys tilings.M.C.Escher has created the tiling of many complicacies or has inlayed design, comprises the repeat patterns of the formed body of animal, plant and things (like gecko, bird, fish and ship).
This specification sheets in the whole text in, " tiling " is to instigate formed body to be molded into as picture mosaic (jigsaw) to be entrenched togather, to form except that very close to each other the optional gap of this horizontal edge or the eclipsed plane of tiling continuously." can tile " and be meant that these formed bodys can tile.
Square, rectangle and sexangle can tile.Can cut film has these shapes with manufacturing simple visual cues.Useless film from this patterning method is few usually, because can be through making these formed bodys with successive straight cuts film.But, according to finding that the simple formed body of this type possibly have the segregation problem in powder composition, more crucially, can not be enough function as visual cues well.
Therefore still have with at laundry treatment compositions, especially in detergent for washing clothes, the most especially washing powder as the manufacturing of the low waste material matrix band of effective visible sensation sign with use relevant problem.
Through making effective lamellar visual cues formed body with the mode that in manufacturing processed, reduces or eliminates waste material from the film cutting is a problem.
Another associated problem are that cost is made the lamellar visual cues of giving the laundry treatment compositions additional function effectively.
Another associated problem of in powder, mixing lamellar visual cues are to make to have they are not emanated and the relative visual cues that is dispersed in the shape and size in the powder that spreads all over equably.
Summary of the invention
According to the present invention, laundry treatment compositions is provided, it comprises laundry treatment base and 0.01 to 10 weight % has the concave lamellar film particles of the differential staining of flat sides and substantially flat circumference, wherein:
A) this circumference is molded at least one straight line that passes this flat sides drafting is being intersected more than two positions and this circumference;
B) this concave lamellar film particles can tile;
C) this concave lamellar film particles and this laundry treatment base form contrast on color, thus this concave lamellar film particles function as visual cues.
Detailed Description Of The Invention
Definition
Visual cues
Be meant the perceptible discrepancy of human consumer in detergent composition.This can be the characteristic of body composition: for example color, viscosity, particle size, maybe can realize through in said composition, mixing visually distinct particle with minor amount.
The visual cues particle
Be meant with minor amount and add in the detergent composition coloured speckle, peplomer or other solid-state visual contrast particle to function as visual cues.
Lamellar visual cues (or sheet)
Be meant the visual cues particle of the planar film material forms of processing formed body.These formed bodys can downcut from diaphragm, or can directly pour into a mould.This type sheet also is known as " peplomer ".
Flower shape or flower shape
Be meant the planar film formed body (or sheet) of flower shape profile with wounded in the battle lobe.Especially template type (stereotypical) flower, it has middle circular zone and many (preferred 6) that therefrom radiate rotate symmetrical dispersive " petal ".
The shape of sheet (lamellar film particles)
Concave lamellar film particles (spill sheet) function as visual cues.In order effectively to realize this function we have found that they must have at least one vision indenture along its circumference.This can arithmetically be expressed as, and as far as each design of spill sheet, must be able to draw out at the straight line that passes the sub-circumference of this peplomer more than two positions.Convex peplomer; Never meet this requirement like square, sexangle and rectangle.Other type arithmetically representing desired shape is that each lamellar film particles must have reflex angle at least one, or it must have the indenture that the curved portion by its circumference forms.
Therefore, the lamellar film particles with two parallel straight edges and two bent limits (spill, another is the convex with same curvature) drops in the wide region of the present invention, as long as it can tile and have and the correlated color of binder composition.
Can distinguish interior angle if exist, then the circumference of each sheet does not preferably have the interior angle less than 100 degree, and must have at least one interior angle (reflex angle) greater than 180 degree.At least two such angles are preferred.Advantageously, in this case, all interior angles are all less than 260 degree, to avoid fragile relatively point.
Most preferably 100 to the interior angle less than 180 degree be to the shape more than the twice of 260 interior angles of spending greater than 180 degree.
The shape of this visual cues is preferably selected from the polygon of following distortion---and its at least two opposite side have deformation of outward extending roughly convex and the corresponding spill deformation that extends internally, thereby these inside and outside deformation can be entrenched togather through tiling.
The shape of this visual cues most preferably is selected from the polygon of following distortion---and Qi Gebian has deformation of outward extending roughly convex and the corresponding spill deformation that extends internally, thereby these inside and outside deformation can be entrenched togather through tiling.
Preferred polygon is a sexangle.
The preferable shape of spill sheet is based on the standard construction of so-called Gosper island shapes (island), because can use single like this and the effective shape of vision.
The spill sheet of two kinds of different sizes also can use the Koch snowflake if desired.Gosper island shape and Koch snowflake are known fractal (fractal) notions, and are used as the basis of inlaying or tiling design by the mathematician before.For the first time iteration Gosper island shape most preferably because it has 18 straight flanges.More describe this shape with reference to the accompanying drawings in detail.
Even can adopt two kinds of complete differences but complementary spill sheet as described herein to obtain to be attributable to low waste material benefit of the present invention.
For making the maximum effect of fragrance visual cues, the shape of this sheet preferably similar certain natural goods and usually and this smell link together; Be petal, flower etc.Advantageously, the shape of this spill sheet and the smell of said composition link together in itself, cause user's best possibly responding because have been found that this.The most advantageously, the color of this spill sheet has increased this sign effect, and color, shape and smell all should be as far as possible near natural goods and identical smells with this, and for example the flower flavor is associated.The size of this spill sheet is so important not as its shape or color.Use is used more signs less than the object representative of full size as this degree of freedom permission of visual cues under the identical table area.For example; The 5 mm dia visual cues that use has 13 square millimeters roughly cross-sectional area can make the technology of in laundry treatment compositions, mixing this spill lamellar visual cues give 50 to 100 such signs in each washing, about 70 of preferred each washing.
The natural shape of the spill sheet that also can be used for tiling is tree, leaf and animal.Particularly advantageous shape as the fragrance visual cues is the shape of similar flower, and especially based on hexagonal shape, this sexangle suitably is out of shape so that its design keeps and can tile.This hexagonal each limit is distortion in the same manner preferably.Therefore, each limit all has protruding with recessed deformation (they are displacement reflections each other), and this hexagonal original parallel opposite face distortion is so that new surface is also substantially parallel but more complicated line.For example, this deformation plance can be that sinusoidal or they can be formed by three interconnection lines.Preferably, new periphery and this hexagonal original circumference are crossing in the midpoint on the limit of former beginning and end modified hexagonal basically.
For being easy to make, most of limits of this spill sheet are straight line preferably, and most preferably they all are straight lines.
Advantageously, all spill sheets all have essentially identical shape.They can all have essentially identical size so that the segregation problem minimizes.
This spill sheet desirably has rotational symmetry.Preferred iteration Gosper for the first time island shape has this symmetry.
This spill sheet can all be a same color, or they can comprise the mixing of different colours.The color (one or more) that can select the spill sheet is with coupling packing (pack) color (one or more).Most preferred color is lavender, pink, yellow, blueness, redness, purple, green and orange.To dark base-material laundry treatment compositions (for example blue, green), can use the contrast spill sheet sign of white.Can use white pigment to introduce whiteness.
Preferably, the shape of this spill sheet and this base-material laundry treatment compositions is directly related in a certain respect.For example, this shape is the outline shape of flower, and said composition has fragrance, especially the fragrance of a flower.Ideally, in this case, this spill sheet also is the color of petal.Another instance is, this spill sheet is the outline shape of the streak of lightening, and said composition comprises and brightens or bleach.In an embodiment again, this spill sheet can be the outline shape of plant, and said composition contains plant milk extract, like aloe vera.
When tiling, this spill sheet desirably is in length and breadth to be arranged, and their vertical alignment, laterally compensation.
Film composition and character
This spill sheet (concave lamellar film particles) is processed by film.Can use the film composition and the character of wide region.Solvable film is preferred.The thickness of film is important.The shearing that too thick or too thin film can not apply in cutting process does not cause under the situation of tearing or being out of shape and effectively and with required complexity cuts.The maximum ga(u)ge of film is 0.4 millimeter, preferred 0.25 millimeter, and most preferably 0.2 millimeter.Minimum thickness is 0.05 millimeter, preferred 1 millimeter.
It is suitable to guarantee them to test tear strength and the brittleness of this film under used thickness.This is simple, and these values become with used definite method.Too soft film is not easy cutting, and too crisp film maybe be cracked and be difficult to obtain desired shape with the productivity of economy.This type fragmentation also improves unacceptable amount of waste material than low dimensional, and these waste materials possibly removed before formed body being added in the laundry composition.As far as polymeric film, can be through softening agent and filler control character as as known in the art.As far as comprising the film of tensio-active agent in addition, the water-content that also can regulate this film is to change these character.
This film can be coloured or opaque, or it can partially transparent.Under each situation, can before or after the cutting film, be printed onto on the film so that monochrome, polychrome or pattern to be provided, like the representative of natural products (like leaf or flower).
Can before cutting, in film, mix and be used for the functional component that clothing is handled.The available composition comprises TAED, Gerol, DTI-1, enzyme, fluorescent agent, covers dyestuff and spices.The most preferably composition that is used in the film is those that only need in powder formulation, exist with utmost point low levels, especially spices, covers dyestuff, bleaching catalyst, fluorescent agent.Because with the interaction of moisture and other composition, this type material potentially unstable in washing composition.Compare with the possible range under spot (speckles) situation, this film also allows to use wider soluble dye.It also has the advantage that dyestuff few (if any) infiltrates the powder body.Soluble dye is superior to pigment usually.
In order in film, to mix sensitive composition,, then be favourable if this film contains Z 150PH (PVA).Select PVA preference ranking so that this film only in just suction under the RH of laundry treatment compositions (for example washing powder).Therefore it prevents that these compositions are by water decomposition with prevent the soluble dye bleeding.
The use design of can tiling cuts into the moulding visual cues with film and has reduced from the waste material of this patterning method and therefore unserviceable film amount discarded or recycling and minimize, and this is important when in film, mixing sensitivity or expensive additive.
Some film additives can improve the effect of visual cues like fluorescent agent.Can comprise that also low amount dyestuff is to resist any yellow.
In the film total amount, based on the sheet mean dose that supplies washing usefulness, functional component is preferably mixed this film with the significant quantity that is used for the clothing processing.
As the lighter weight substitute of film, can make net or the open architecture of polymer-based material and they are cut into formed body with the mode identical with film.Can the tile identical use advantage of formed body of acquisition.Term " film " is intended to comprise the chip architecture of this type same function.
The preferred film compsn comprises soluble polymer and tensio-active agent.
Optional further composition is: the auxiliary agent that auxiliary film is made, for example separant and water.Except the effect of its controlling diaphragm relative humidity, water also helps film plasticising and its solubleness of adjusting.
This polymkeric substance can be selected from water-soluble, film-forming polymers, in particular for the preparation washing powder those.Preferred polymkeric substance is included under any temperature of 293 to 333K in water under agitation in 30 minutes dissolving and/or dispersive polymkeric substance fully.
Preferred water-soluble polymers is like Davidson and Sittig, Water-Soluble Resins, and Van Nostrand Reinhold Company can pour into a mould those of film forming or solid matter described in the New York (1968).Preferred water soluble resin comprises Z 150PH; Ether of cellulose; Polyethylene oxide; Starch; PVP K120; SEPIGEL 305; Polyvinyl methyl ether-maleic anhydride; HPMA; Styrene-maleic anhydride; Natvosol; Vltra tears; Polyoxyethylene glycol; CMC 99.5; Polyacrylate; Alginate; Acrylamide copolymer; Guar gum; Casein; Ethene-maleic anhydride resin series; Polymine; Type 3U; Ethylmethylcellulose; Hydroxyethylmethyl-cellulose; Sugar.The water-soluble poval film-forming resin of lower molecular weight is preferred.
The Z 150PH that this paper preferably uses has 1,000 to 1,000,000, and is preferred 5,000 to 250,000, for example 15,000 to 150,000 molecular-weight average.Hydrolysis or alcoholysis be meant on the resin wherein acetate moiety by hydroxyl ,-the completion percentage of the substituted reaction of OH group.The hydrolysis scope of the 60-99% of Z 150PH film-forming resin is preferred, and as far as the water-soluble poval film-forming resin, preferred hydrolysis scope is about 70-90%.Most preferred hydrolysis scope is 80-89%.Term " Z 150PH " used among the application comprises the polyvinyl acetate ester cpds with the disclosed hydrolysis degree of this paper.
Another suitable polymers is by having the polyvinyl alcohol film that the polyvinyl alcohol copolymer that contains the functional comonomer of carboxylate radical is processed.
The PVA of preference ranking is only in just suction under the RH of granular detergent composition.Thus, it prevents that this other film component is by water decomposition with prevent the soluble dye bleeding.
This spill sheet can comprise 10 to 80% polymkeric substance or polymeric blends.
Although can use any suitable tensio-active agent or surfactant system.This tensio-active agent is preferably aniorfic surfactant, if especially it is added in the particulate compsn that comprises washing assistant.
Suitable aniorfic surfactant is well known to a person skilled in the art.The instance of high foaming sulphonate or sulfated surfactant comprises sulfonated alkylbenzene, particularly has C 8-C 15The linear alkylbenzene sulfonate of alkyl chain length; Primary and secondary alkyl-sulphate, particularly C 8-C 15Primary alkyl sulphates; Alkene sulfonate; Alkylxylene sulfonate; Dialkyl sulfosuccinate; And fatty sulfonate.Sodium salt is usually preferred.
At open source literature, for example at " Surface-Active Agents and Detergents ", I and II volume, Schwartz, Perry and Berch show, in provide further information.
Preferred anionic surfactants type tensio-active agent is a sulfonated alkylbenzene, linear alkylbenzene sulfonate (LAS) more particularly, and it is preferably with 12 to 24 weight %, and more preferably 12 to 22 weight %, the especially amount of 15 to 22 weight % exist.
Primary alcohol sulfate, (PAS), particularly C more preferably again 8-C 18, preferred C 12-C 15Primary alcohol sulfate.Special preferred surfactants is that carbon chain length is 12 primary alcohol sulfate, (PAS).Can use visual cues peplomer that contains maximum 50%PAS.
This film can comprise the second surface promoting agent in addition.This second surface promoting agent is preferably selected from amphoterics, zwitterionics, non-ionics and ethoxylation aniorfic surfactant.
Preferred both sexes second surface promoting agent is an amine oxide.Most preferred amine oxide is a cocounut oil n n dimetylaniline oxide compound.
Preferred zwitter-ion second surface promoting agent is a trimethyl-glycine, especially amido betaines, for example cocoamidopropyl.
Preferred non-ionic type second surface promoting agent comprises primary alconol and secondary alcohol ethoxyl compound; Especially use the C8-C20 fatty alcohol of average 1 to the 20 moles of ethylene oxide ethoxylation of every mol of alcohol, more particularly use the C of average 1 to the 10 moles of ethylene oxide ethoxylation of every mol of alcohol 10-C 15The primary and secondary fatty alcohol.
Preferred ethoxylation anionic second surface promoting agent comprises sulfated alkyl ether (sulfated ethoxylated alcohol).
That be adapted at equally being used as the second surface promoting agent in the visual cues of the present invention is C 8-C 18Alkyl monoethanol amide, for example coconut monoethanol amide.
Second surface promoting agent system used in this peplomer can comprise minor amount in addition, for example is less than 5% cationic surfactant of this film.
Tensio-active agent can be with maximum 90 weight %, preferred maximum 75 weight %, and the amount of most preferably maximum 60 weight % is included in this film.
Non-woven stability tinting material can be with 0.001 to 0.5 weight %, and the amount of preferred 0.10 to 0.20 weight % is included in this film composition.That preferred film tinting material is selected from is orange, yellow, pink, blue, red, green, purple and lavender.
The manufacturing of spill sheet
Used the tiled shape of spill sheet can be passed through impact molding or the manufacturing of grain roller patterning method, uses these methods to compare with known star or circular visual cues and reduces waste material to a certain extent.But, making that we are surprised to be, we also find, via the rotation patterning method, can be with small dia with the extremely low waste material output manufacturing shape that preferably can tile.
Small dia is meant from being 2 to 10 millimeters to the opposite preferably have about 5 millimeters mean diameters on one side.Can make and seem the very similar more shape with straight flange of complicated bent limit shape.This produces " truly " shape with acceptable cost economically.For example, the tiled design of the flower shape shown in Fig. 6 (having 18 crossing straight flanges) almost can not be distinguished the user of enough type of vraisemblance flower so that laundry composition in shape.This shape therefore be superior to square with in addition be superior to sexangle; Especially when its compsn that will add also comprises spices; The most especially the color at flower is selected from natural flower simulation tone, when for example orange, yellow, pink, blue, red, green, purple and lavender.
As far as the design shown in Fig. 6; In cutting process, produce some leftover bits inevitably, this can through the screening and the desired design shape separate wholly or in part be low to moderate 0.5 to 1 weight % in generation recycling with waste material per-cent (pressing the weight of film).Not the 10 weight % that the amount of the film of required spill sheet form should be lower than film total amount in the said composition in this laundry composition, preferably be lower than 5 weight %, most preferably be lower than 2 weight %.This cutting waste material mainly is a spill sheet grotesque and/or too little so that effectively function as visual cues.Advantageously, this laundry composition contains ratio target spill plate shape and the little particle of size of 0 to 1.5 weight %, preferably under economically viable situation as far as possible near 0.
The spill sheet mixes in the laundry treatment base
As far as the laundry soap bar, when manufacturing process finishes soon, add visual cues and be destroyed to avoid them.As far as washing liquid, they can suspend described in EP 1319706.As far as the washing powder compsn, they definitely can not be emanated in making (comprising mixing, operation and transportation) process inadequately.
This laundry treatment compositions advantageously provides in having coloured packing of main theme color.Desirably, one or more color-match of this spill sheet should be packed color; Most preferably, they are monochromatic and mate the main theme color of this packing.
Laundry treatment base is preferably solid detergent composition; It most preferably is a granular laundry detergent.
In this particulate compsn, for improving the sense of vision of visual cues, it should have than the much bigger cross-sectional area of binder composition particulate MV.But this causes potential problems in manufacturing and/or transportation, because emanate easily with the difform particle of body (bulk), and the effectiveness that this causes the unacceptable feed dosage volatility of this visual cues and destroys them.
For make the segregation level remain on (identification number of wherein washing usefulness is enough) in the acceptable limit at every turn, this spill sheet should have density, thickness, diameter and the shape in delimit.These are through measuring and by the check checking.
There are indications that because visible spill sheet is counted " accident " factor of aspect at any time, in fact experiential separating water is flat has positive effect to performance.
Weight and density are to make segregation remain on the key parameter that can accept in the limit.Weight is the function of thickness, diameter and shape.
For avoiding the inappropriate segregation in the powder composition, the weight of visual cues should be 1 to 4 milligram, preferred 1.5 to 3.5 milligrams.Film density should be 200 to 800 grams per liters, preferred 230 to 500 grams per liters, most preferably 250 to 400 grams per liters.In principle, weight is high more and density is high more, and it is low more to emanate---until ultimate value.But this is uneconomic, because the incorporation in powder has to improve (as far as given visual effect, it is constant that spill sheet number keeps).Can come controlling diaphragm density through the degree of inflation that changes in the film manufacturing processed.
The segregation experiment
On the powder bed of pouring out, measure with the standard depth of colour meter.Measuring diameter is about 5 centimetres.
This white powder has following color (5 measurements):
L a b
On average 96.08 0.14 2.59
stdev 0.07 0.02 0.10
Contain the petal same powder that tiles spill sheet visual cues of 0.15 weight % pink and have following color (10 measurements).
L a B
On average 95.75 0.85 2.66
stdev 0.36 0.44 0.06
Therefore, this mixing of pink spill sheet of can tiling causes the a-value to improve (having big stdev) and causes the higher stdev of L value.The raising of stdev is the result of the tiled spill sheet of random amount when at every turn measuring.This is the conclusive evidence that preceding text are discussed " accident " factor.
Effectiveness as visual cues
A) in laundry treatment compositions
Their effects have been strengthened with the use of spill sheet of the color-match of packing as visual cues.With base-material laundry treatment compositions agents enhance overall effect also is very useful.For example, add in base-material washing powder that some green spots come to light and the spill sheet of petal color is united and strengthened flower shape outward appearance, this has strengthened natural perfume used in the said preparation, and further strengthens by the similar mass-tone of this packing.
Selection has recess, and particularly the spill sheet of the regular shape of the approaching recess (1 to 2 millimeter curvature) of scale and typical laundry treatment compositions particulate convex surface is of value to outward appearance.In addition,, make us remembering that the spill sheet of natural shape is especially desirable, if especially this shape also can link together with corresponding natural fragrance if this spill sheet will provide visual cues for fragrance.
B) in use, when the compsn that comprises the spill sheet adds in the water
By making the controlled experiment of washing by hand, confirm that flower shape is superior to hexagonal potential user's preference.The hand washing group member is asked to describe that washing is experienced and the attribute of this gained cleaning product, and aspect the pure and fresh property of the whiteness of washes and washes, they are higher than the sexangle visual cues to the evaluation of flower shape visual cues.Overall washing is experienced and also is cited as more excellence.
The present invention is only described now for example, and with reference to its accompanying drawing.

Fig. 8 is the synoptic diagram that is designed by the spill sheet with recess (intrusion) that single protruding bent limit and single corresponding concave edge form.
The complicacy of multiple identical shaped 1 that the shown Fig. 1 design of can tiling, 1 has six rotational symmetric " petal " separately, and they give the impression that each shape looks like flower.Each " flower " can be regarded as modified hexagonal.The former initial line 2 of one of sexangle has been out of shape to have roughly recessed 3 and roughly protruding 4 with respect to original hexagon profile.Recessed and bossing is bonded together in the midpoint of former initial line.In this case, each several part is identical with another part rotation.If recess 3 is around intersecting mid point Rotate 180 degree, it can be superimposed upon on the protuberance 4.The area that this means this shape is compared constant with original sexangle, but because diameter improves, and sense of vision improves, and because this flower shape outward appearance, overall appearance and as the increased functionality of visual cues.
Fig. 2 has shown can the tile variant of shape of the flower shape of Fig. 1.This spill sheet as shown in have 5 millimeters overall diameters.They are vertically arranged, and transversely compensate one another.With respect to hexagonal limit 5, recessed round than the corresponding section of Fig. 1 with convexity 6,7.Recessed 6 do not have the reflex angle of the clear-cut as among Fig. 1 at the contact place.This indenture is crooked, and it is through being bent to form necessary indenture and reflex angle.
Fig. 3 has shown the dissimilar of design of can tiling, and its middle concave sheet 8 and 9 has two kinds of different shape and size.For each macroparticle 8, two small-particles 9 are arranged.The spill sheet has at least one indenture and corresponding interior reflex angle.
Fig. 4 merges the design of simply can tiling that forms by three sexangles.Spill sheet 10 is identical on shape and size.Each spill sheet particle has the interior reflex angle 11 of 240 degree and the adjacent interior angle of two 120 degree.This spill sheet can pass through cutting and separating, does not stay the waste material that is formed by the zone between the sheet, and has only a spot of trilateral from the corner, and this depends on the spill sheet columns and the line number of cutting from monolithic membrane.This can screen and in said composition, use big part.
Fig. 5 has shown the modified hexagonal design, and it is the iteration first time that is known as the shape of Gosper island shape.At this, seven less sexangles of stack on original sexangle 11 are so that six parts 15 with outstanding original sexangle 11 in these less sexangles.Equally, form corresponding recessedly 16, and protrusion and recessed has equal area and around the mid point 14 rotation symmetries of original sexangle 11.Fig. 6 has shown the deformed shape that forms when the design of iteration Gosper island shape cuts out spill sheet 17 according to this first time in detail.This spill sheet have interior reflex angle 18 and with each in two adjacent interior obtuse angles 19 of reflex angle 18, this type obtuse angle 19 is 2: 1 with the ratio of reflex angle 18.This produces simple flower shape design, and the edge of this shape only uses straight line.Fig. 7 has shown how these spill plate shapes vertically arrange 20,21,22, and how to form walking crosswise of two groups of dislocation by the alternate position on vertical.
Fig. 8 has shown the simple spill sheet design 25 that can tile.It has the recessed zone of the bending that is formed by limit 26, and angle 27 and 28 is respectively obtuse angle and acute angle.By bent limit 26 necessary reflex angle is provided.
Embodiment
Manufacturing has the polymeric film of following composition:
Z 150PH (polymkeric substance) 46.5%
Sodium lauryl sulphate (tensio-active agent) 46.5%
Tinting material/dyestuff (pink) 0.02%
Water and submember 6.98%
Through these compositions being dissolved in the water to form homogeneous solution, the manufacturing film.Make this solution through inflation unit, at this with this solution of inclusion of air.Then aerated liquid is poured into a mould film forming and dry.
Film thickness is the 0.18-0.19 millimeter, and its specific density is about 0.3.It is cut into the flower shape shape that can tile according to Fig. 6 and 7.The maximum diameter of this shape is 5 millimeters, and the cross-sectional area on one of the plane of this flower shape is about 16 square millimeters.
Use two kinds of methods that this film is cut into desired shape: rotation cutting and punching press.The former produces some leftover bits, and it reduces through screening.The latter produces useless film net, and it needs recycling.But the amount of this type film is less than the amount of waste material that the design that can not tile through punching press generates.
With the used similar mode of other composition, the spill sheet that downcuts is mixed white carbonate STPP help in the surfactant based washing powder of the LAS that washes (its particulate granularity is less than 1 millimeter) at the last dosing of washing powder manufacturing process.With hand or with metering device these formed bodys are quantitatively added mixing equipment, they mix in this product at this.This mixing is to use that rotation mixing device machinery carries out or carries out through air being blasted this powder.After mixing, transport final powder to filling machine, powder is adjusted in the coloured sack or box of different size at this.
