Stretchable absorbing composite and manufacture thereof

[Detailed Description of the Invention]

<Field of the Invention> The present invention relates to absorptive material or structure, and also the elastic absorptive compound material for absorbing and holding a fluid, speaking restrictively. <Prior art> The absorptive structure type [, such as a monolayer which includes a material called mixture of cellulose fluff, a synthetic fiber, and fluff and a synthetic fiber now, multilayer structures, and such various structures accompanied by superabsorptive material, / various ] exists now. When that such structures have mentions some important desirable characteristics or characteristics, it is the pliability at the time of a rapid transfer speed and rate of absorption, high capacity, high holding power, and dryness, the pliability at the time of humidity, the non-privation at the time of dryness, the non-privation at the time of humidity, and regurgitant [ low ]. These achieve other characteristics and effect of the feature at the sacrifice of the above-mentioned characteristic and the feature of the singular number or plurality, or as for me, the problem which occurs repeatedly about the present absorptive structure hears that it is made to increase. Although the absorbing capacity can generally serve as the maximum with the combination of fluff and a superabsorber, As one of the problems accompanying this combination, at the time of dryness with that non-privation, fluff will have the tendency to be re-distributed by a wearer's motion and action, and, for this reason, that absorbing capacity in the maximum humid region will fall. Similarly, after becoming humid, this combination gets wet, can cook it and it is collected into the form of the separate lump of The, i.e., it cluster-izes, and for a wearer, this is very unpleasant and appearance's is bad [ this ]. One solution over an above-mentioned problem is providing the mechanism which maintains the non-privation of absorptive material in the form a fixed quantity of binding materials, a synthetic fiber, etc. being introduced. Although this may increase the non-privation at the time of dryness and humidity, the fall of the absorbing capacity and pliability is usually caused, and this is caught as the material which Tough touch carries out comparatively by a wearer, or a structure. Means > for solving A task In one embodiment of the present invention, the elastic absorptive compound material for accepting the exudation liquid and excrement containing the elastic layer of the liquid permeability between a liquid permeability layer, a fluid impermeable layer, an absorptive layer and a liquid permeability layer, and a fluid impermeable layer, and absorbing and holding them is provided. Stretch bonding of this elastic layer is carried out to other layers, it is it at that relaxation time, and it forms a plurality of Fold in other layers. In another embodiment of the present invention, they are a liquid permeability layer and liquid permeability, the stage which equips with an elastic layer, an absorptive layer, and a fluid impermeable layer, the stage which unites and carries out bonding of the elastic layer and each class in the state where stage; extension of was done which expand an elastic layer, and the stage of releasing the layer by which bonding was carried out -- and The manufacturing method of elastic absorptive compound material including the stage which it is at the release time of an elastic layer, and forms a plurality of Fold in a liquid permeability layer, an absorptive layer, and a fluid impermeable layer is provided. Definition "Elasticity" used in the inside of this book, and a claim "Elastic characteristic" The word "extension" and "elasticity", That is [ it is elongated at least 25% of the loose length ], it can be elongated up to at least 1174 times of the loose length (25% of growth). And when applied power is release * Carried out, in order to specify material or a compound thing which recovers at least 10% of the growth, it is used with compatibility. If this definition is followed, it is at the release time of the addition power in 25% of growth, and must recover material or the compound material to at least about 15% of growth. For example, a sample length of 100 cm is elongated to a length of at least 125 cm, it is also a profit deer at the release time of addition power, and when it can recover to the length below about 115 cm, the material or compound material is suddenly regarded in "elasticity." The relaxation length may be elongated 25% or more for the material of elasticity or elasticity, or many of compound material, it is many of these at the release time of addition power, and even the original relaxation length is recovered to near it. Since the material of the class of these latters is the object of the present invention, generally it is fond. elastomer textiles Quality nonwoven by which the melt blow was carried out at such materials only not only in the web of elasticity, such as casting or a blow-molding film, or an elastic film -- a nature web of non-woven textile called nib is also contained. The word "bonding" may mean uniting two layers or compound material by combination, adhesion, connection, and attachment directly or indirectly. For example, over the three whole layer, when a bond is effective, bonding of the three layers will be carried out directly. These three layers are said to carry out bonding when bonding of two-layer [ outermost ] is directly carried out along with the circumference, in order to take in the middle class in between, i.e., to use a sand inch. The word a "transfer layer" is a layer of material which mainly orients the flow of fluid in the direction of X which aims to pass the thickness of a layer. A "wicking layer" is a layer which mainly orients a fluid style in many directions within the X-Y plane which is a plane specified with the length and width of a layer. <Example> Reference of Drawings 1 and 2 includes body side liner 4 of liquid permeability, the elasticity of liquid permeability or elastomer layer 6, absorptive medium 8, and outside cover 10 of fluid impermeability in one embodiment of elastic absorptive compound material 2. This specific embodiment smell * The and elastomer layer 6 are made perviousness by a plurality of apertures 12 arranged in it. Drawing 1 indicates the elasticity or elastomer layer 6 in the state where it is not loosened and elongated to be compound material 2 in the state where the layer was separated. In manufacture of compound material 2 described in detail by the following, it is expanded to desirable growth, and liner 4, elastomer N6, absorptive assembly 8, and cover 10 unite elastomer layer 6 next, and bonding is carried out. After bonding, compound material 2 is loosened so that elastomer layer 6 may recover the extension state. doing in this way, gathering of liner 4, absorptive medium 8, and the outside cover 10 is carried out as shown in Drawing 2, and they are a plurality of Facial -- 14 and a plurality of air pockets 9 are formed on compound material 2 inner sides or both the sides of elastomer layer 6 of the inside. with a natural thing, it is Facial -- while 14 is mutual, it essentially forms or generates space. it is Facial when elastomer layer 6 is elongated by single direction called the lengthwise direction shown by the arrow in Drawing 5 -- generally sequence 16 (Drawings 5 and 15, Drawing 16) of 14 and air pocket 9 is the perpendicular direction to the direction, i.e., the lengthwise direction of elastomer layer 6. elastic absorptive compound material 2 finished when elastomer layer 6 was elongated in the many directions of X, for example, the direction, and the direction of Y -- the -- it has a pattern like an insect of the quilt style as shown inA [ 5 ] figure and Drawings 17 and 18. the --B [ 5 ] figure expresses the expanded sectional view which lets compound material 2 in the 2nd figure pass. since elastomer layer 6 is in the loose state where it is not elongated, Rajna 4, absorption material 8, and covers 10 are a plurality of Facial -- gathering is carried out to sequence 16 of 14. these layers, i.e., layer 4, absorption material 8, and cover 10 are Facial -- since gathering is carried out so that it may be set to 14, a layer is flat or the surface area per square inch will become large compared with the case of being planate. It is extended respectively and It is 14 has a plurality of small fine wrinkles 18 by the inside of the surface 20 which extends outside to elastomer layer 6 and which faces. it is Facial -- although it is 14 and wrinkles 18 at the relaxation time of elastomer layer 6 and they are formed, these are inside of this book, and Facial -- 14 -- having -- rather than -- big irregular nature -- wrinkles 18 -- having -- rather than -- fine irregular nature -- distinguishing -- a sake -- identifying -- having -- Listen . wrinkles 18 are Facial at the point of enlarging more surface area per square inch of compound material 2 when compared with the flat or planate surface again -- said is carried out to 14 and it is used for the object. elastic absorptive compound material 2 is Facial -- since it had 14, wrinkles 18, and the bigger surface area by the favor of air pocket 9 than per square inch, it turned out that it increases, so that the function of a specific layer is surprised. For example, since it changes gathering of the liner 4 into a bulky state, the surface area per square inch becomes large, and it brings a result in which the degree of dryness of a body surface increases. As the surface area of a fluid acceptance layer becomes large with a natural thing, the quantity of the fluid in which a layer can influence becomes larger. similarly, absorption material 8 is Facial -- it is the favor of 14, wrinkles 18, and pocket 9, and has the capacity per [ superior to in order to receive a fluid and to absorb and hold it ] IJn grade area. Compared with absorption material flat [ the same trim size ] or planate, this takes a lot of fluids and treatment paddle management becomes easy to be carried out by increase of the surface area per square inch of absorption medium 8 also here. it is Facial when it says about outside cover 10 -- 14 and wrinkles 18 provide a cover quieter than while the body moves, and give appearance like cloth. Liquid permeability object side liners 4 are polypropylene, polyester, polyethylene, rayon, and Chiss. of -- the sheet or nonwoven web of polyolefin textiles [ like ] may be sufficient. Liner 4 may be a synthetic fiber, a natural fiber or a nonwoven web of those mixtures, a plastic film with a hole, polystyrene-foam Webbing material, or Scrim material similarly. Preferably, liner 4 is spunbonded polyethylene with the amount of tsubos of about 0.2 per square yard to about 1.0 oz, or Span Ponde Sodo boriblobylene. Preferably liner 4 is spunbonded polyethylene with the amount of tsubos of about 0.2 per square yard to about 1.0 oz. The material which can make liner 4 about one of specific embodiments or modification embodiments may be influenced by the exact physical properties or characteristic desired about liner 4. generally liner 4 is hydrophobicity -- about [ about 0.05 to ] -- 8. Om E / second / ctA -- to consist the high fluid transfer rate preferably called penetration rate of about 0.5 to about 2.5 m l / second / cIl! is desired. Liner 4 shows again the Was done feel characteristic which becomes empty. An extensive material can be used as elastomer layer 6, and not only the web of elastic films, such as casting or a blow-molding film, but a nonwoven elastic web called the nature of elastomer textiles nonwoven web by which melt blow or Sepang bonding was carried out, for example is contained in this. As it was called a melt blow liner, Staple Tips Ohm absorption material, or a film, for example, entailment of the elastomer may be carried out to any one layer. When cooled, the self-adhesion type elastomeric material which is shrunk and serves as elasticity, and the material of others like the elastic film which can be pushed out and processed are also suitable for using as elastomer layer 6. Material which is [ for making the elastomer textiles by which the melt blow was carried out still more preferably ] helpful in order to make elastomer layer 6, A-B-A It is a block copolymer denoted by the general formula '(in addition, inside A of a formula and A' are end blocks or segments of a thermoplastic polymer containing a styrene portion respectively.). B is conjugate diene or an elastomer polymer intermediate block called low-grade Al Ken. The material of this - boat fishing Typhoon is indicated by U.S. Pat. No. 4,333,782 of the June 8, 1980 issue to 11, A, and r'1eniak. The same material is indicated in United States patent No. 4.418.123 published to William L and Bunnelle on November 29, 1983. the A-B-A' fluke copolymer of marketing which was saturated with the thermoplastic polystyrene end block or segment sometimes called 5-EB-3 polymer, or has fundamentally saturated poly intermediate block (ethylene butylene) B or segment -- for example It is alike and raton G. It is available under the KRATON G trademark from 5hel 1 Che+wical Company, such as 1650, Kraton G-1652, Kraton GX-1657, and Kraton G-2740X. As the example of others of the elastomeric material used by the present invention, For example, although it can obtain by a brand name called DuPontde Nemours and Company to E, T, and Hytrel, it is polyester elastomer material [ like ], although it can obtain by a brand name called Goodrich and Corspany to B, F, and Es tane -- polyurethane elastomer material [ like ] -- and For example, although it can obtain by the brand name of R11san Company to Pebax, there is polyamide elastomer material [ like ]. A suitable elastic film which is distinguished from an elastic nonwoven web can also be used according to the present invention. For example, it is the elastic film currently sold by A of Ohio Akron, and SchulmanCorporation by the brand name of Po1y trape. Extension or extension is possible for elastomer layer 6 from about 10% to about 800% of the relaxation length, and it has the outstanding restoration rate of at least about 10%. Including aperture 12 which lets it pass in the direction which faces to absorption medium 8, and makes fluid pass or transport to it quickly again, elastomer layer 6 loses the flow of the fluid to an opposite direction, or is pressing it down at worst. Generally it is equipped with the aperture in all the forms where the transfer characteristic or speed of desirable fluid is obtained as a result. Elastomer layer 6 may be liquid permeability by the peculiar stoma in material. For example, if a melt blow process gives a stoma into melt blow products, and a surface-active agent is added when required, melt blow products will become a hydrophilic thing. The desirable amount of tsubos of elastomer layer 6 is about 200 g from about 10 g per square meter, and the amount of good Milestone is about 150 g from about 60 g per square meter further. Absorptive medium 8 may be made of all suitable absorptive materials called the core of melt blow textiles, such as the cellulose material or polypropylene like the air fabrication core of wood pulp textiles, polyethylene, and polyester, for example. The web to which bonding carding of a synthetic fiber or the natural fiber was carried out again as for absorptive medium 8, It may be a mixture of Stachyl fibers, such as a compound thing of polypropylene, polyethylene, and the melt blow textiles of polyester with which the cellulose material was also mixed, or rayon, and a cellulose material. There is a bridge, Connection(ed) polyacrylic acid salt, etc. in the example of a suitable superabsorptive material so that the methyl cellulose of starch and starch polyacrylic acid graft polymerization, denaturation polyvinyl alcohol, and the absorptive polymer by which graft polymerization was carried out may be formed. The layer of various absorptive structures, such as a melt blow layer of polypropylene and a layer of fluff accompanied by superabsorptive material, may also be contained in absorptive medium 8. Absorptive medium 8 may be made from foam type material or Kotuome material again. In one desirable embodiment, absorptive medium 8 contains joint material 30% (weight percentage) and polyester 70% like Chisso of the mixture which a super-absorbent with the amount of tsubos of about 16 g per square meter is mixed, and has the amount of tsubos of about 70 g per square meter. polyethylene 40% (weight percentage) in which absorptive medium 8 has the amount of tsubos of about 150 g per square meter with which the super-absorbent with the amount of tsubos of about 16 g per square meter was mixed in another desirable embodiment -- if it solves, it will be pulp 60% of a mixture. The outside cover may be made of what kind of suitable fluid impermeable material, and may be made of material of gas perviousness in fluid impermeability. Outside cover 10 is made of polyethylene or a polypropylene film with a thickness of about 1.5 mil, preferably about 0.3 to about 0.6 mil preferably. An outside cover may be the melt blow material or the film material made in the copolymer of polyethylene, such as acetic acid vinyl ethylene, methyl acrylate ethylene, ethyl acrylate ethylene, polyvinyl chloride, and nylon, polypropylene, or polyolefin again. As a material which can permit others, there is three-layer material of the single layer of the material of the above-mentioned paste eve by which Sepang bonding was carried out, Span pumping melt blow material two-layer or the Sepang bonding melt blow, and the Sepang bonding agent. The suitable charge of foam can also be used as outside cover 10, and EVA mixed with polyester, polyurethane and polyester, or polyurethane is contained in this. Outside cover 10 has the feel characteristic outstanding again. Although Drawings 1 and 2 show compound material 2 which has elastomer layer 6 between liner 4 and absorptive medium 8, they can also exchange these two so that absorptive medium 8 may adjoin liner 4 and elastomer layer 6 may adjoin cover 10. If Drawings 3 and 4 are referred to here, another embodiment of elastic absorptive compound material is shown. In this operation [fi, transfer layer 22 is added between liner 4 and elastomer layer 6. There is one in generally [ the object of transfer layer 22 ] providing a rapid fluid transfer in the direction of Z which is a perpendicular direction to the plane of elastic absorptive compound material 2. Thus, by providing a rapid fluid transfer in the direction of Z, the rate of absorption of elastic absorptive compound material 2 increases. Transfer layer 22 has the preferably low re-humid-ized characteristic and high humid elasticity again. One method of decreasing the re-humid characteristic is because a liner is Detachment(ed) from absorption material using air pocket 9 etc. One method of increasing humid elasticity is use of a synthetic fiber or foam. A rapid fluid transfer in the direction of Z shown in the word of being perpendicular when Drawings 3 and 4 are referred to can be attained by one method by turning the textiles of transfer layer 22 in the direction of Z. (air-1aying) an air twist process can attain this orientation. Transfer layer 22 is the nonwoven web made from thermoplastic textiles, such as polyethylene and polyester, preferably. Transfer layer 22 may be the web by which bonding carding was carried out, the web by which the melt blow was carried out, the spunbonded webs, or those mixtures of thermoplastic textiles. Speaking restrictively, transfer layer 22 being a web which contains suitable binding materials, such as Chisso and low melting point powder, by weight percentage, contains polyester fiber 70% by weight percentage 30%, and has the amount of tsubos of about 50 g per square meter and by which bonding carding was carried out. The desirable amount range of tsubos is 70 g from about 30 g per square meter. Transfer layers 22 may be binding materials, such as Kotuome material like the carding web of the polyester by which bonding was carried out to the spunbonded polypropylene carrier sheet and Chisso, and low melting point powder. Speaking restrictively, being the Kotuome structure containing polyester 75% as a web by which bonding was carried out to 25% of spunbonded polypropylene carrier sheet by weight percentage, and by which carding was carried out. The weight percentage of polyester and polypropylene is changeable if needed. The embodiment shown in Drawings 3 and 4 can have similarly transfer layer 22, elastomer layer 6, and absorptive medium 8 which were positioned in a different order from what is illustrated with it being about the embodiment of Drawing 1 and elastic absorptive compound material 2 in the 2nd figure. As long as it is between liner 4 and outside cover 10, it is permissible in any order. Preferably, a layer is positioned as shown in Drawings 3 and 4. If Drawings 6 and 7 are referred to here, another embodiment of elastic absorptive compound material 2 by which the wicking layer was added between elastomer layer 6 and absorptive medium 8 is shown. Wicking layer 24 is useful to transport a fluid in the direction of X and the direction of Y which are in the plane of compound material 2 so that the rapid absorption by absorptive medium 8 may be provided quickly. A rapid transfer of the fluid of the direction of X and the direction of Y is provided by orienting the textiles of wicking layer 24 horizontally so that it may be seen in Drawings 6 and 7. If it puts in another way, generally the textiles in wicking layer 24 are perpendicular to the textiles in transfer layer 22. These textiles are level, namely, various processes, such as a humid twist (wet-1aying) and carding, can attain orientation in X and the direction of Y. Generally wicking layer 24 can be made from a material same type as transfer layer 22. Wicking layer 24, elastomer layer 6, and absorption material 8 can be arranged in any order between liner 4 and outside cover 10. However, Drawing 6 shows a desirable order of liner 4, transfer layer 22, elastomer layer 6, wicking layer 24, absorptive medium 8, and outside cover 10. If Drawings 8 and 9 are referred to here, liner 4, elastomer layer 6, wicking layer 24, absorptive medium 8, and outside cover 10 are further included in the embodiment of another elastic absorptive compound material 2. Position exchange of elastomer layer 6 and the wicking layer 24 can be carried out between liner 4 and absorptive medium 8 as shown in Drawing 10 and Drawing 11. Drawings 12 and 13 show the modification embodiment of Drawing 6 and Drawing 7 in the state where it was exchanged in layers 22 and 24. Since elastic absorptive compound material 2 contains the thermoplastic component in each of the layer, both the non-privation and elasticity of a dry state and a Warming up state are given, and this is an advantage functional [ both ] and sensuous. The capability to maintain the shape of a basis is given to compound material 2 for bulking (swelling) of the elasticity material made by elastomer layer 6, or gathering, and this is the main factors for attaining the more outstanding containment. The absorption feature of compound material 2 is subject to positive influence for dense contact of the layer in compound material 2 which combined with the overall bulking or gathering, and underwear 26. For example, the transfer speed of the fluid from the surface to absorptive medium 8 increases, and when wood pulp is contained as one ingredient of absorptive medium 8, humid destruction or condensation of a cellulose material is pressed down at worst. By using transfer layer 22 and wicking layer 24, increase of the absorptivity in a bond point is obtained and the adverse current characteristic is controlled. The explanation about how an absorptivity increases at a bond point or how the adverse current characteristic is pressed down at worst again is seen in United States patent pipe No. 4,397,544 registered on February 4, 1982 directed in this book as reference. If Drawing 14 is referred to here, in order to form pattern roll 58 which has on it a plurality of projection parts 62 arranged alternatively, and NIP (mill opening) 64 in the meantime, anvil (anvil block) 60 which adjoins pattern roll 58 is contained in device 51. Both can rotate alternatively in the direction of an arrow, and the thermal control also of pattern roll 58 and the anvil 60 is alternatively carried out so that the temperature chosen as the surface of each of the outermost part may be given. Either pattern roll 58 or anvil 60 and its both can move toward the thing of another side, and it changes alternatively the pressure given to NIP 64. as mentioned above, as explaining projection part 62 below -- what kind of -- it Desirable and carries out, and it is and is alternatively arranged on pattern roll 58 even at a pattern. Liner transfer layer roll 66 by which may be the above Kotuome materials or preliminary fabrication may be separately carried out on roll 68 again and which provides the two-layer web containing liner 4 and transfer layer 22 is included in this device 57. elastomer layer roll 68 -- wicking layer roll 70 provides elastomer layer 6, absorptive medium roll 72 provides wicking layer 24, and absorptive medium 8 and outside cover roll 74 provide outside cover 10. Various roll supply things are convertible so that arrangement of a layer may be changed, as shown even in Drawing 13 from Drawing 1. In order to elongate elastomer layer 6 before passing NIP 64, the revolving speed of elastomer layer roll 68 is alternatively reduced by below the revolving speed as which other rolls 66.70.72 and 74 were chosen. Since elastomer roll 68 rotates more at a low speed, elastomer layer 6 is expanded for it by the lengthwise direction in the distance from roll 68 to NIP 64. When wished, elastomer layer 6 can also be expanded a transverse direction or simultaneous by using the known means of others like extension roll 76 or a tenter (tenter) frame. Generally, extension roll 76 is carrying out the Curvature form or the arch so that it may cross and a transverse direction may be made to elongate elastomer layer 6 between Pull rose Being done. extension of elastomer layer 6 or control of the direction of growth is the adjustment and Facial which were united with the object of the characteristic of finished compound material 2 -- also not only in shape determination but in the handling and processing of compound material 2 in a manufacturing process, it is the effective feature. The amount of tsubos of a layer, the rigidity and the growth grade of N6 that elastomer N6 and others were chosen with the natural thing, and its direction may be chosen so that the desirable characteristic may be provided in finished compound material 2. when only a lengthwise direction or a transverse direction is made to elongate an elastomer layer, it is Facial as shown in Drawing 5, 15 figure, and 16 figure -- sequence 16 of 14 is obtained as a result. the same -- extension or growth of elastomer layer 6 of both a lengthwise direction and a transverse direction -- as a result -- the -- the shape of the shape of quilt as shown inA [ 5 ] figure, 17 figure, and 18 figure is brought about. Since the extension forms an aperture in elastomer layer 6 irrespective of one way or the many directions when desirable, or when required, one or all the rolls 76 can be equipped with the aperture formation means of the projection part which is sharp or sharpened. As mentioned above, by being able to arrange projection part 62 alternatively and carrying out it like this on the surface of the outermost part of pattern roll 58, the region as which elastic absorptive compound material 2 was chosen can be made into an immovable thing, and the elastic characteristic can be controlled and changed. The effect of immobility-izing can carry out city IJ4 wholesale by fluctuating the number of the bond points per unit region, or the surface area of each bond point in a unit region. The layer by which bonding was carried out passes along between cutting roll 80 which has on it a plurality of braids 82 arranged alternatively, and anvils 78 as it leaves NIP 64. Braid 82 is alternatively positioned so that a bonding layer may be cut into all forms. Although pattern roll 58 with projection part 62 is the one method of uniting and carrying out bonding of the layer using heat, By the method based on the present invention, other bonding methods are also taken into consideration and ultrasonic bonding, adhesives bonding, and other suitable bonding methods are included in this. Once the layer by which bonding was carried out passes NIP 64, the elastomer layer can loosen and can carry out gathering of the other layers. In the general embodiment of compound material 2, thermoplastic liner 4, thermoplastic transfer layer 22, thermoplastic elastomer layer 6, thermoplastic wicking layer 24, heat good Tsu absorptive medium 8, and thermoplastic outside cover 10 exist.
