The rectangular cross section formed can be expressed as S AxB. On the same date, The wearing area can be expressed as a circular area with an equalized diameter d. Then, the equalized diameter D can be calculated from the equation: S = 1/4 ^ D2, where S is a known area of a rectangle. (Of course, the equalization of a circle The true diameter of a circle with a diameter). The equalizing radius is 1/2 of the equalizing diameter. The "false thermoplastic" combined with "material" or "composition" is used to indicate that by increasing the temperature, disintegration It can be softened under the influence of a suitable solvent or other means: to the extent that it can produce a flowable state (in its condition, it can be shaped as desired, more specifically, it can be processed to form a fine powder suitable for forming an elastic structure) ) Materials and compositions. Pseudo-thermoplastic materials can be formed under the influence of, for example, the combination of heat and pressure. Pseudo-thermoplastic materials are different from thermoplastic materials because the softening or liquefaction of pseudo-thermoplastic materials is caused by the presence of softeners or Caused by solvents, Without a softener or solvent, it would not be possible to produce the flowable state required for forming by any temperature or pressure, because the pseudo-thermoplastic material does not "melt." The effect of water content on the glass transition temperature and melting temperature of starch can be determined by differential scanning calorimetry (such as ZAζη ^ and Hosny in "Cereal Chemistry," Volume 64, Number 2, pages 121_124, Bp. ) Measurements.

At a grand scale, the elastic structure, when placed on a flat surface, contains thin and flat sheets of ㈣. However, at a microscopic level, this structure may include a first-level area with a first-level height and several first-level areas that are scattered throughout and extend outward from the frame area to form a second-level dome or "Pillow, o / strength property" does not have properties determined by numerical integration in the plane of the elastic structure. Common strength properties are strengths possessed by more than one area. These strength properties of the elastic structure of the present invention include density, basis weight, height, opacity, and wrinkling frequency (if the structure is shortened), but not Limited to this. For example, if the density is a common strength property of two different regions, the density value in one region may be different from the density value in another region. Regions (e.g., the 'first region and the second region') are distinguishable regions that can be distinguished from each other by individual strength properties. “Basic weight” refers to the weight per unit area (measured in grams of force) of the starch elastic structure. This unit area is obtained from the surface of the starch fiber structure. The size and shape of the unit area by which the basic weight is measured depends on the relative and absolute sizes and shapes of the areas with different basic weights. "Density" is the ratio of the area's basis weight to its thickness (which is perpendicular to the plane of the elastic structure). Apparent density is the basis weight of the sample divided by the diameter converted with the appropriate unit incorporated therein. The apparent bifurcation when used here has units of grams per cubic centimeter (g / cm3). The "diameter" refers to the macroscopic thickness of a sample measured as described below. The diameter needs to be different from the height of different regions (which is the micro characteristics of the region). "Glass transition temperature", Tg, is the transition of materials from self-adhesive or rubbery state

"Mechanical direction, (or MD) is the direction where the elastic structure made by the manufacturing equipment = parallel to the flow. The "cross mechanical direction" (or CD) is a direction that is straight with the mechanical side = + and parallel to the general plane of the elastic structure to be produced. "X", "Y", and τ represent the traditional Cartesian coordinate system ^, the mutually perpendicular coordinates "X" and "Υ" define the χ-γ reference plane, and "z," is defined perpendicular to XY plane. "Z_direction" means any direction perpendicular to the χ_γ plane. Similarly, "Z-dimension," means the dimension, distance, or parameter measured parallel to the direction of the dagger. When an element (eg, a molded element) is bent or deplane, the X_γ plane follows the structure of the element. In fact, a "substantially continuous" area (area / network / frame) can be connected to any two points by an uninterrupted line running completely over the area of the line length. That is, a substantially continuous area is substantially "continuous" in all directions parallel to the first plane and ends only at the end edge of the area. The combination of "substance" in continuous is used to indicate that although absolute continuity is better, different ... Small deviations in absolute continuity can be tolerated, as long as these deviations do not significantly affect the designed and desired flexibility Structure (or molded element) performance.

"'Melting temperature'" means a temperature or temperature range in which the starch composition is melted or softened enough to be processed into starch fibers according to the present invention. It is important to understand that the composition of a meal is a pseudo-thermoplastic composition and therefore cannot exhibit pure "melting" behavior. The strength treatment / JHL degree refers to the temperature at which the starch composition of the present invention powder can be formed by the 'e.g.' drawing action.

The more common functional groups of these multifunctional resins are nitrogen groups, such as amine groups and methyl groups attached to nitrogen Alcohol group. The fine month of polyethene is also found to be useful in the present invention. In addition, the temporary wet strength tree month (such as Caldas 10 (manufactured by Carlit in Japan) and coBond 1000) (Manufactured by National Starch & Chemical Co., Ltd.) can be used in the present invention. For the present invention, 'a crosslinker-based wet strength resin KymeneTM, the range of about 80 to about 10% by weight and more particularly about About 0.00% by weight to about 3% by weight. In order to prepare starch fibers suitable for the elastic structure 100 of the present invention, the starch composition needs to exhibit certain rheological behavior during processing, such as specific stretching Viscosity and specific capillary number. Of course, the type of processing (for example, melter's electrospinning) can indicate the desired rheological properties of the powder composition. The tensile or elongation viscosity (77 e) is related to the starch composition Related to melt stretchability, and for stretch Processing (such as the preparation of starch fibers) is particularly important. The tensile viscosity includes three types (which depend on the deformation type of the composition): uniaxial or simple tensile viscosity, biaxial tensile viscosity, and pure shear Stretching viscosity. Uniaxial stretching viscosity is particularly important for uniaxial stretching processes such as mechanical stretching, melt blowing, spunbonding, and electrospinning.

For traditional fiber-spun thermoplastic materials (such as polyolefins, polyamides, and polyesters), these traditional thermoplastic materials and their There is a strong correlation between the tensile viscosity and the shear viscosity of the blend.

This correlation is quite strong. 'So, the fiber industry can rely on melt shear viscosity when selecting and formulating melt-spinnable materials. Melt stretch viscosity is very It is rarely used as a screening tool in the industry. Therefore, it is surprisingly discovered that the starch composition of the present invention does not need to exhibit this correlation between shear and stretch viscosity. The starch composition here can exhibit the typical melt flow behavior of non-Newtonian fluids , And thus can exhibit strain hardening behavior, that is, the tensile viscosity increases as strain or deformation increases. For example, when a high polymer selected according to the present invention is added to a powder composition, the shear viscosity of the composition remains relatively constant Unchanged or slightly reduced. Based on conventional wisdom, this starch composition is expected to exhibit reduced melt handleability and is not expected to be suitable for melt stretch processing. However, it was surprisingly found that the starch composition system here showed a significant increase in tensile viscosity, even when a small amount of a high polymer was added. Therefore, the starch composition here has been found to have promoted melt stretchability and is suitable for melt stretch processing, especially those including melt blown, spunbond, and electrospinning. Has a shear viscosity of less than about 30 basca · seconds (pa · s) (more specifically about 0 Pa · s to about 10 Pa · s, and more specifically about 8 Pa · s) The starch composition (measured in accordance with the test method disclosed later) can be used for the smelting, pulverizing, and thinning treatment method. Some of the powder compositions here may have low melt viscosity, so that they can be mixed in traditional polymer processing equipment typically used for viscous fluids, such as static mixtures equipped with metering pumps and spinnerets , Shipping or other processing. The shear viscosity of the starch composition can be determined by the molecular weight and molecular weight distribution of the starch powder, the molecular weight of the high polymer, and the paper size used.

Description of the invention (30) Furthermore, 'High polymers that are substantially compatible with starch can promote the melting and stretching of starch composition Sexuality is most effective. It has been found that when a selected high polymer is added to the composition, the starch composition used for melt stretching treatment has an increased tensile occupancy by a factor of at least 0, typically 'when the selected high polymer is added At this time, the composition of the present invention powder exhibits an increase in the stretch viscosity of a factor of about 10 to about 500 (more specifically, about 20 to about 300, and more specifically about 30 to about 100). The higher the polymer content, the greater the increase in tensile viscosity. A high polymer can be added to adjust the tensile viscosity to a value of 200 to 2000 Pa · s at a Hencky strain of 6. For example, polypropylene amidamide having a molecular weight (MW) ranging from 0.001% to 0.1% may be added to include a starch composition. The form and content of the starch used can also have an impact on the stretch viscosity of the starch composition. Generally, when the amylose content of starch decreases, the stretch viscosity increases. Furthermore, in general, when the molecular weight of the powder within the specified range is increased, the tensile viscosity increases. Recently, in general, as the content of powder in the composition increases, the tensile viscosity increases. (Conversely, in general, as the content of additives in the composition increases, the tensile viscosity decreases). The temperature of the powder composition can significantly affect the tensile viscosity of the powder-killing composition. For the purpose of the present invention, conventional methods for controlling the temperature of the powder composition can be used if appropriate for the particular method used. For example, in a specific example in which powdered fibers are produced by extrusion through a mold, the mold temperature has a significant impact on the stretch viscosity of the starch composition extruded therefrom. Generally, as the temperature of the composition increases, the tensile viscosity of the powder composition decreases. The temperature range of the powder-killing composition can be about 2 (TC to about 18th generation, more 297 mm) 4 Γ ^ --------- line—η (Please read the precautions on the back before filling this page ) 33 555905 A7

It is necessary to understand that the presence or absence of solids in the starch composition will affect it The required temperature 2 The Truton ratio (Tr) can be used to express the tensile flow behavior. The Truton ratio is defined by the ratio between the tensile viscosity (e) and the shear viscosity (s).

Tr = 7? C (e *, t) / v s? Where the tensile viscosity is determined by the deformation ratio (ε ·) and time ⑴. For Newtonian fluids, the uniaxially stretched Truton ratio has a constant of three. For a non-Newtonian fluid 'composition like this, the tensile viscosity is determined by the deformation ratio (ε ·) and time ⑴. It has also been found that the melt-processible composition of the present invention typically has a Truton ratio of at least about 3. Typically, when measured at a processing temperature and a tensile ratio of 700 s · 1 at a Hencky strain of 6, the Trudon ratio ranges from about 10 to about 5,000, and particularly from about 20 to about 1 10,000, and more particularly about 30 to about 500. The applicant has also found that in specific examples in which starch fibers are produced by extrusion, the capillary number (Ca) of the starch composition is important for melt processing when passing through an extrusion die. Capillary number refers to the value of the ratio of viscous fluid force to surface tension. Close to the exit of the capillary die, if the viscosity is not significantly greater than the surface tension, the fluid fibers will return to dripping, which is generally referred to as "atomization". Capillary system is calculated according to the following equation:

Ca = (η s · Q) / (^ · r2 · cr) where 7 / s is the shear viscosity measured at 3000 s_1 shear rate (basca · sec); Q is the volumetric fluid flow rate through the capillary mold (M3 / s); r is the radius of the capillary mold (meters) (for non-circular spinneret, equalized diameter / half paper size applies Chinese National Standard (CNS) A4 specification (210 X 297 mm) 34 I.

Shear viscosity is the same factor and affects it in a similar way. As used herein, the term "inherent" combined with capillary number or surface tension refers to being free from external factors (eg, the presence of a galvanic fluid) Affected properties of starch composition. The term "effective" refers to properties of starch composition that are affected by external factors such as the presence of galvanic fluids. In a specific example of the present invention, the melt-processable starch composition has an intrinsic capillary number of at least 0.01 and an effective capillary number of at least 1.0 when passing through the mold. When there is no static electricity, the capillary number needs to be greater than that for fiber formation stability. 1. For the strong stability of the forming fiber, the capillary number needs to be greater than 5. When there is static electricity, the charge repulsion offsets the surface tension effect, so the essential capillary number (measured when no charge exists) can be less than 丨. When the electromotive force is applied to the formed In the fiber, the effective surface tension is reduced and the effective capillary number is increased according to the following equation: Although the capillary number can be expressed in different forms, it can be used to determine the representative equation system of the essential capillary number:

This material will flow through the tip of the nozzle to form small droplets, and then drop by individual droplets under the action of gravity. As the electromotive force on the system increases, the droplet size becomes smaller and starts accelerating to the grinding mechanism. When the electromotive force (25 kV for this sample) reached a critical value, drips no longer formed at the nozzle tip, and small continuous fibers flowed out of the nozzle tip.

The starch material is heated to an elevated temperature sufficient to form a pseudo-thermoplastic melt. This temperature is typically higher than the glass transition temperature and / or melting temperature of the forming material. The pseudo-thermoplastic melt of the present invention is a t-composition fluid having a male shear rate dependent on viscosity as known in the art. Viscosity decreases with increasing shear rate and increasing temperature. The starch material can be heated in a closed volume in the presence of low concentration water to convert the starch material into a pseudo-thermoplastic melt. The confined volume can be a confined volume or a volume created by the sealing effect of the feed occurring within the screw of the extrusion equipment. The pressure generated in the closed container includes the pressure due to the vapor pressure of water and the pressure due to the compression of the material in the extruder screw and sleeve. Chain-breaking catalysts (which reduce molecular weight by breaking down sugars in the starch macromolecules to reduce the average molecular weight of starch) can be used to reduce the viscosity of pseudo-thermoplastic melts.

Description of the Invention (46) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. U.S. Patent No. 4,44G, 597 (the disclosure of which is incorporated herein by reference for the description of the micro-shrink mechanism) is a detailed description of "wet-micro shrinkage. Briefly, wet-micro shrinkage involves making fibers with low fiber consistency. The mesh is transferred from a first element (such as a porous element) to a second element (such as an open-woven fabric loop) moving at a slower speed than the first element. Now, it is believed that if the dying knife fiber can be formed and counted Starch fibers can be kept in a sufficiently elastic condition before being transferred from a relatively slow moving support (such as the forming element 500) to a relatively fast moving support (such as the molding element 2GG), which may effectively make the number; The meal fiber shrinks slightly, thereby shortening the elastic structure to be produced. The rate of the core element 200 may be about 1% to about 25% compared to the rate of the shaped element 500. Figure 9A shows the method according to the present invention. A specific example, in which starch fiber can be deposited at an angle of eight (which can be from 丨 to 89., and more particularly from about 5. to about 85) to the molding element 2000. This specific example is considered to have a suspended portion Part 2 j 9 of the molding element 200 is used It is particularly advantageous. The "starch fiber 17a" is deposited at an angle to the molding element 200, so that the air 215 formed between the suspended portion 2 丨 9 and the reinforcing element 250 can be closer to the long and elastic powdery fiber 7a, and promote The rhenium fiber more easily fills the interstitial space 215. In Figure 9A, the starch fibers 17a are deposited in the molding step 200 in steps such as, for example, two kinds of gap space 219—upstream gap space 215 & and downstream gap space 21% —can be angled from the starch Deposited to the molded element 200 profit. Depending on the specific formation of the molding element 2000 (especially the geometry and / or orientation of its floating portion 219), the downstream angle A may be equal to or different from the upstream angle b. The denier starch fiber is placed on the fiber contact side of the molding element 200.

In the description of the invention (47), the number of fibers at least partially conformed to its three-dimensional pattern. In addition, various methods can be used to create or promote the conformation of the starch fibers to the three-dimensional pattern of the molding element 2000. One method involves applying a fluid pressure differential to several starch fibers. This method is particularly advantageous when the το 200 series fluid is permeable. For example, the vacuum device 550 placed on the back side 202 of the fluid-permeable molding element 200 may be configured to apply vacuum pressure to the molding element 200, and thus to the number of starch fibers placed thereon, FIG. Under the influence of vacuum pressure, some starch fibers can be flexed in the openings 220 and / or the interstitial spaces 215 of the molding element 200, or conform to their three-dimensional pattern. All three regions of the phase #elastic structure 1000 may generally have equal basis weights. By deflecting a part of the starch fibers within the openings 22o, the bifurcation of the formed pillows 120 can be reduced relative to the density of the first imprinting area 110. The area 11 that is not deflected in the opening 220 can be engraved by compressing the elastic structure in the rolling. If imprinted, the density of the imprinted area 11 will be increased compared to the density of the pillow 12 and the density of the third area. The density of the area 11 and the third area 13 that are not flexed in the opening 220 are higher than the density of the pillow 120. The third region 130 may have a density between the engraved region 110 and the pillow 120. Referring to FIG. 1A, the elastic structure ι00 according to the present invention can be considered to have three different densities. The highest density area is a high-density engraved area 11. The imprinted area 110 corresponds in position and geometry to the frame 210 of the molding element 200. The lowest density region of the elastic structure 100 is the pillow no, which corresponds in position and geometry to the opening 220 of the molding element 200.

Description of the invention (48) The density between the pillow 120 and the engraved area 110. The "inclined portion" 230 is the surface of the frame 210 having a vector component extending from the fiber receiving side 201 of the molding element 200 to its rear side in the direction of 2022Z •. The inclined portion 230 does not extend completely through the frame 210 like the opening 22. Therefore, the difference between the oblique portion 230 and the opening 220 can be tolerated as the opening 220 presents a perforation in the frame 210, and the inclined portion 230 presents a hidden hole, crack, pit or cut in the frame 210. The three areas of the structure according to the present invention may be considered to be placed at three different heights. As used herein, the height of an area refers to its distance from the reference plane (ie, X-Y plane). For convenience, the reference plane can be viewed horizontally, where the height from the reference plane is vertical. The height of a specific area of the starch fiber structure 100 can be measured using any non-contact measurement device known in the industry to be suitable for this purpose. A particularly suitable measuring device is a non-contact laser displacement sensor (with a beam size of 0.3 x 12 mm in the 50 mm range). A suitable non-contact laser displacement sensor is sold by the company "MX1A / B. In addition, contact gauges known in the industry can be used to measure different heights. This type of gauge is described in the United States patent Case No. 4,300,981 (issued to Carstens), the disclosure of which is incorporated herein for reference. The structure 100 according to the present invention is placed on a reference surface, and the imprinted area 11 is in contact with this reference surface. The pillow 12 and the third region 13 extend perpendicularly from the reference plane. The different heights of the regions 10, 120, and 13 can also be achieved by using molded parts having different depths or heights with their three-dimensional patterns 2 〇〇 formation, as shown in Figure 5A. These three-dimensional patterns with different depths / heights can be made by frosting a preselected portion of the molding element 200 to reduce its height. Furthermore, the curable materials The molding element 200 can be made by applying the Chinese paper standard (CNS) A4 specification (210 X 297, published 51 555905) on this paper size. 5. Description of the invention (49) Three-dimensional shielding. By using different Depression / Protrusion of Depth / Height : Dimensional shield, which can form the corresponding frame 21o with different heights. The traditional technique of forming a surface with different south degrees can be used for the above purpose. It is designed to be improved by a vacuum device 55o (Figures 8 and 9). ) Or the possible negative effects of the sudden application of a fluid pressure differential in a vacuum extraction box 600 (Figure 9) (which may force certain fibers or parts thereof to pass through the molding element 200, and thus result in elasticity The so-called pinholes are formed inside the structure), and the rear side of the molding element can be "texturized" to form microscopic surface irregularities. Such surface irregularities are advantageous in some specific examples of the molding element 200 Because it avoids forming a vacuum seal between the rear side 202 of the molding element 200 and the surface of the paper-making equipment (such as the surface of a vacuum device), thereby creating a "leakage" therebetween, and therefore slowing down the preparation of the elastic structure 1 of the present invention The undesired results of applying vacuum pressure in the ventilation drying method of 〇〇. Other methods of generating this leak are disclosed in U.S. Patent Nos. 5,718,806; 5,741,402; 5,744,007; 5,776,3 1 1 and 5,885,421, The disclosures of etc. are incorporated here for reference. This leak can also use the so-called "differential light transmission technology," which is produced by, for example, the US Consumer Intellectual Property Office of the Intellectual Property Bureau of the US Department of Economics, printed national patents 5,624,790; 5,554,467; 5,529,664; 5,514,523 and 5,334,289, the disclosures of which are incorporated herein by reference. The molding element can also be applied by applying a photosensitive resin coating to a reinforcing element having an opaque portion, and then applying the coating. It is made by exposing to light with an activating wavelength of a shield with transparent and opaque parts and a reinforced element. Another way to create irregularities on the rear surface involves using it to form textures. The paper dimensions are in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) 555905 A7 B7

Such as a vacuum device 550 (which applies a vacuum pressure (ie, negative, less than atmospheric pressure) to several thousand fibers through the fluid permeable molding element) or a fan (not shown, which applies a positive pressure to a number (Fiber) devices can be used to facilitate flexing of a number of fibers within the three-dimensional pattern of the molded element.

Furthermore, Fig. 9 illustrates the optional steps of the method of the present invention, in which the starch fiber is an elastic material sheet 800 (which is an endless belt including rollers 800a and 800b and contacting the fiber) cover. That is, the number of fibers is sandwiched between the molding element 200 and the elastic material sheet 800 for a period of time. The elastic material sheet 800 may have an air permeability less than that of the molding element 200, and may be air impermeable in some specific examples. Applying a fluid pressure difference p to the elastic sheet 800 causes at least a portion of the elastic sheet to flex to the three-dimensional pattern (in some examples, flexed therein) of the molding element 200, thereby tending to compact the starch fibers. Comply with Molding Element No. 2000-15 (the disclosure of which is incorporated herein for reference = the main configuration of the equipment and method using elastic material sheets. In addition to the fluid pressure difference, mechanical pressure can also be Is used to facilitate the formation of the three-dimensional micropattern of the elastic structure 1GG of the present invention.

One or more pairs of pressure rollers 900a and 900b, and 900c and 900d can be used to make the starch fiber placed on the molding member 200 more completely conform to its three-dimensional pattern. The pressure generated by the pressurizing roller can also be pre-arranged (if required), for example, the pressure generated between the rollers 900c and 900d may be greater than the pressure between the rollers 900a and 9001). In addition, the ring-shaped pressurizing tape 950 that orbits the rollers 950a and 950b can press-mold a part of the fiber side 2000 of the element 2000 so that the elastic structure therebetween is engraved with 100. The pressing surface may be smooth or have its own three-dimensional pattern. In the following examples, the 'pressurized surface can be used as an embossing device to form a clear micro-pattern of protrusions and / or depressions in the elastic structure 1000, which is a two-dimensional pattern with the molding element 200 Cooperation or individually. Furthermore, the pressurized surface can be used to deposit various additives (e.g., softeners and inks) to the produced elastic structure 200. Conventional techniques, such as ink roll 910 or a spraying device (or sprayer) 920, can be used to directly or indirectly deposit various additives to the manufactured elastic structure 1200. As known in the art, the construct 100 can be selectively shortened. The shortening can be accomplished by wrinkling the structure 100 from a rigid surface (more particularly from a cylinder, such as the cylinder 290 shown in Figure 9). As known in the industry, the wrinkling effect is performed by a scalpel 292. Wrinkling can be accomplished in accordance with U.S. Patent No. 4,919,756 (issued to Sawdai on April 24, 1992, the disclosure of which is incorporated herein by reference). In addition, the shortening effect can be achieved by the slight shrinkage as described above.

Explanation of the invention (53) J test method A. Shear viscosity The shear viscosity of the composition is measured using a capillary rheometer (Rheograph 2003, manufactured by Goettfert). The measurement system uses a diameter 〇 and 30 mm length L (i.e., L / D = 30) capillary dies. The dies are attached to the lower end of the sleeve (which is maintained at the test temperature ranging from 艺 to the other range). Preheated The sample composition to the test temperature is loaded into the sleeve section of the rheometer. Filling the sleeve section (about 60 g of sample is used). The sleeve is kept at a specific test temperature⑴. If bubbles are generated on the surface after loading, the densification before the operation test is used to remove the trapped air in the sample. Piston Arranged to cause the sample to advance from the sleeve through the capillary mold at a selected set of rates. As the sample passes through the capillary mold from the sleeve, the sample experiences a pressure drop. The apparent shear viscosity is the pressure drop and the flow rate of the sample through the capillary mold. Calculate. Then 10 g (apparent shear rate) is plotted against log (shear velocity), and the graph is matched with a power-law equation 々, where k is the material constant and / is the shear rate. The male viscosity of the composition is extrapolated to the shear rate of s_1 using a power-law relationship. B. The tensile viscosity is printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. (Made by Goettfert). The measurement was performed using a semi-hyperbolic mold design (with a starting diameter of 15 mm (D start), a final diameter of 0.75 mm (D end), and a length (L) of 7.5 mm). The semi-hyperbolic shape of the mold is defined by the two equations, where Z = the axial distance from the starting diameter, and where D (z) is the mold straight at the distance from the starting z to D.
