The fibrous element forming composition is a polar solvent based composition. In one example, the fibrous element forming composition is an aqueous composition that includes one or more fibrous element forming materials and one or more active agents.

Although the fibrous element and/or fibrous structure of the present invention is in solid form, the fibrous element forming composition used to make the fibrous element of the present invention may be in liquid form.

The fiber element spinning process requires that the fiber element have initial stability as it exits the spinning die. The capillary number is used to characterize this initial stability criterion. In die conditions, the number of capillaries may be at least 1, and/or at least 3, and/or at least 4, and/or at least 5.

In one example, the fibrous element-forming composition exhibits a capillary number of at least about 1 to about 50, and/or at least about 3 to about 50, and/or at least about 5 to about 30. Allows effective polymer processing of fiber elements.

ηは、ダイの条件における流体粘度（長さ×時間当たりの質量の単位）であり、
σは、流体の表面張力（時間の二乗当たりの質量の単位）である。速度、粘度、及び表面張力が一連の一貫した単位で表されるとき、得られる毛管数は、それ自体の単位を有さず、個々の単位は無効になる。

V is the fluid velocity at the die exit (unit of length per hour),
η is the fluid viscosity (unit of length×mass per hour) under the conditions of the die,
σ is the surface tension of the fluid (unit of mass per square of time). When velocity, viscosity, and surface tension are expressed in a series of consistent units, the resulting capillary number has no units of its own and individual units are invalid.

Capillary number is defined for the conditions at the exit of the die. Fluid velocity is the average velocity of the fluid passing through the holes in the die. Average speed is defined as:

Ｖｏｌ’＝体積流量（時間当たりの長さの三乗の単位）であり、
面積＝ダイ出口の断面積（長さの二乗の単位）である。

Vol'=volume flow rate (unit of length cubed per time),
Area=die exit cross-sectional area (unit of length squared).

If the die holes are circular holes, the fluid velocity can be defined as follows:

Ｒは、円形の穴の半径（長さの単位）である。

R is the radius (unit of length) of the circular hole.

Fluid viscosity is temperature dependent and may be shear rate dependent. The definition of shear thinning fluid includes dependence on shear rate. Surface tension depends on the composition of the fluid and the temperature of the fluid.

(A) A fibrous element comprising one or more fibrous element forming materials, and one or more deterrent agents, and optionally one or more activators and/or one or more polar solvents (such as water). Providing the forming composition 22 from a tank 24 or the like; and (b) providing the fiber element forming composition 22 through a spinning die 26 or the like with one or more fiber element forming materials, optionally one or more. Spun into one or more fibrous elements 10, eg, filaments, containing the active agent of claim 1 and one or more inhibitors. In one example, one or more deterrents may be applied to the surface of one or more fibrous elements and/or to a fibrous structure containing fibrous elements. In another example, the fibrous element may be free or substantially free of deterrent, in which case the one or more detersive agents are present during and/or after spinning of the fibrous element. Need to be applied to the surface of.

The fiber component forming composition may be transported between tank 24 and spinning die 26 with or without pump 30 via a suitable pipe 28. In one example, a pressurized tank 24 suitable for batch operation is filled with a fiber element forming composition 22 suitable for spinning. A pump 30 such as a Zenith® PEP II type pump manufactured by Colfax Corporation (Monroe, NC, USA), a Zenith pump division, and having a capacity of 5.0 cubic centimeters per revolution (cc/rev). It may be used to facilitate transport of the fiber element forming composition 22 to the spinning die 26. The flow of the fiber element forming composition 22 from the pressure tank 24 to the spinning die 26 may be controlled by adjusting the number of revolutions (rpm) of the pump 30 per minute. A pipe 28 is used to transport the fibrous element-forming composition 22 (as represented by the arrow) from the tank 24 to the pump 30 and into the die 26, using the pressure tank 24, the pump 30, and the spinning die 26.

As shown in FIGS. 3 and 4, the spinning die 26 allows the fluid (eg, air) to pass through it as it exits the fiber element forming holes 32, causing the fiber element forming composition 22 to elongate into fiber elements 10. A plurality of fibrous element forming holes 32 may be included, including melting capillaries 34 surrounded by concentric elongated fluid holes 36 that facilitate the attenuation.

In one example, the spinning die 26 shown in FIG. 4 includes two or more circular extrusion nozzles (fiber element forming holes 32) spaced from each other at a pitch P of about 1.524 millimeters (about 0.060 inches). Have columns of. The nozzle has an individual inner diameter of about 0.305 millimeters (about 0.012 inches) and an individual outer diameter of about 0.813 millimeters (about 0.032 inches). Each individual nozzle includes a melting capillary 34 surrounded by an annular and divergent flared orifice (concentric elongated fluid holes 36) to supply the individualized melting capillaries 34. The fibrous element-forming composition 22 extruded through the nozzle is surrounded and elongated by a generally cylindrical stream of moist air supplied through an orifice to produce the fibrous element 10.

Attenuated air may be provided by heating compressed air from a source with an electrical resistance heater, for example, a heater manufactured by Chromalox (Pittsburgh, Pa., USA), a division of Emerson Electric. Appropriate amount of flow was added to saturate or near saturate the heated air in the condition in electrically heated and thermostatically controlled delivery pipe. The condensate was removed in an electrically heated, thermostatically controlled separator.

The nascent fiber element has a temperature of about 149° C. (about 300° F.) to about 315° C. (about 600° F.) by an electric resistance heater (not shown) and is fed through a drying nozzle and spun onto the nascent fiber. It is dried by a stream of dry air ejected at an angle of about 90° with respect to the overall orientation of the element. The dried fibrous element imparts a pattern, eg, a non-random repeating pattern, to a belt or fabric, and in one example, a soluble fibrous structure formed as a result of collecting the fibrous element on the belt or fabric. It may be collected on a collecting device such as a belt or cloth that can be used. A vacuum source may be added just below the forming zone to assist in the recovery of the fibrous element into the recovery device. Spinning and recovery of the fibrous element produces a soluble fibrous structure that includes intertwined fibrous elements (eg, filaments).

In one example, any volatile solvent (eg, water) present in the fiber element forming composition 22 during the spinning process is removed as the fiber element 10 is formed, such as by drying. In one example, greater than 30 wt% and/or greater than 40 wt% and/or greater than 50 wt% of the volatile solvent (eg, water) of the fiber element forming composition is produced during the spinning process, for example, The fibrous element 10 to be removed is removed by drying.

And/or with from about 10% to about 50%, and/or up to about 40%, and/or up to about 30%, and/or up to about 20% by weight of an active agent; From about 20% by weight and/or from about 25% by weight and/or from about 30% by weight and/or from about 40% by weight and/or up to about 80% by weight and/or about 70% by weight % And/or up to about 60% by weight and/or up to about 50% by weight of a volatile solvent (eg water). The fibrous element-forming composition comprises a small amount of another active agent, eg, less than 10%, and/or less than 5%, and/or less than 3%, and/or less than 1% by weight of the fibrous element-forming composition. Plasticizers, pH adjusters, and other activators may be included.

The fibrous element-forming composition is spun into one or more fibrous elements and/or particles by any suitable spinning process (eg, meltblowing, spunbonding, electrospinning, and/or spin spinning). In one example, the fibrous element forming composition is spun by meltblowing into a plurality of fibrous elements and/or particles. For example, the fibrous element forming composition can be pumped from a tank to a meltblown spinnerette. Upon exiting the one or more fibrous element forming holes in the spinneret, the fibrous element forming composition is attenuated by air to produce one or more fibrous elements and/or particles. The fibrous element and/or particles may then be dried to remove any residual solvent (eg water) used for spinning.

The fibrous elements and/or particles of the present invention may be collected on a belt (not shown), eg, a patterned belt, eg, in an intertwined manner, so that a soluble material containing fibrous elements and/or particles is included. A fibrous structure is formed.

Three dissolution test specimens (3.8 cm x 3.2 cm) are cut from the soluble fiber structure sample using a punching die so that they fit within a 35 mm slide base 44 with an open area dimension of 24 x 36 mm.

Each test piece is separately fixed to the 35 mm slide base 44.

Place the magnetic stir bar 42 in the 600 mL beaker 38.

Tap water (or equivalent) by twisting the faucet, measure the water temperature with a thermometer and, if necessary, adjust with hot or cold water to maintain the test temperature. The test temperature is 15°C ± 1°C water. When the test temperature is reached, fill the beaker 240 with 500 mL ± 5 mL of tap water at 15 °C ± 1 °C.

Place the filled beaker 38 on the magnetic stirrer 40, switch on the stirrer 40 and adjust the stirring speed until a vortex is generated and the bottom of the vortex reaches the 400 mL mark of the beaker 38.

The 35 mm slide base 44 is fixed to the crocodile clamp 48 of the 35 mm slide base holder 46 so that the long end 50 of the slide base 44 is parallel to the water surface. The crocodile clamp 48 must be centered on the longer end 50 of the slide base 44. The depth adjuster 52 of the holder 46 is installed so that the distance between the bottom of the depth adjuster 52 and the bottom of the crocodile clamp 48 is 28±0.318 cm (11±0.125 inch). There must be. This placement positions the sample surface perpendicular to the water flow. An example of a slightly modified placement of the 35 mm slide and slide holder is shown in FIGS. 1-3 of US Pat. No. 6,787,512.

In one operation, the fixed slide and clamp are lowered into the water and the timer is activated. Lower the sample so that it is in the center of the beaker. Disintegration occurs when the soluble fibrous structure is disrupted. Record this as the disintegration time. Once all visible soluble fibrous structure has left the slide, pull the slide out of the water while continuing to monitor the solution for uneluted fragments of soluble fibrous structure. Elution has occurred when all the fragments of the soluble fibrous structure are no longer visible. Record this as the elution time.

Three replicates of each sample are tested and the average disintegration time and average elution time are recorded. Average disintegration time and average elution time are in seconds.

The average disintegration time and the average elution time are normalized by basis weight by dividing each by the sample basis weight determined by the basis weight method defined herein. Basis weight normalized disintegration and elution times are in units of gsm (s/(g/m ² )) of seconds/sample.

Diameter Test Method The diameter of individual fibrous elements, or fibrous elements within a soluble fibrous structure or film, is determined using scanning electron microscopy (SEM) or light microscopy and image analysis software. Select a magnification of 200-10,000 times to properly expand the fibrous element for measurement. When using SEM, the sample is sputtered with gold or palladium compounds to avoid charging and vibration of the fiber elements in the electron beam. Manual procedures are used to measure fiber element diameter from images (on a monitor screen) obtained using SEM or light microscopy. Use the mouse and cursor tools to find the edge of the randomly selected fiber element and then extend the other edge of the fiber element over its width (ie, perpendicular to the direction of the fiber element at that point). Measure up to. A calibrated, calibrated image analysis tool provides a scale for taking actual readings in μm. For fibrous elements within the soluble fibrous structure or film, SEM or light microscopy is used to randomly select some fibrous elements from the sample of soluble fibrous structure or film. At least two parts of the soluble fibrous structure or film (or fibrous structure within the product) are cut and tested in this manner. For statistical analysis, such measurements are performed at least 100 times in total, and then all data are recorded. The data recorded is used to calculate the mean value of the fiber element diameters (average), the standard deviation of the fiber element diameters, and the median fiber element diameter.

Another useful statistic is the calculation of the amount of aggregates of fiber elements that are below a certain upper limit. To determine this statistic, the software is programmed to count how many of the diameters of the fiber element results are below the upper limit, and this count (divided by the total number of data, 100% Multiply) is recorded as a percentage as being less than or equal to the upper limit (e.g., percent having a diameter less than or equal to 1 macrometer, or% being submicron). We represent the measured diameter (in μm) for individual circular fiber elements as di.

If the fibrous element has a non-circular cross section, the measurement of the diameter of the fibrous element is determined as and as the hydraulic diameter. The hydraulic diameter is the cross-sectional area of the fibrous element multiplied by 4 and divided by the perimeter of the cross section of the fibrous element (outer perimeter in the case of a hollow fibrous element). Number-average diameter, or average diameter, is calculated as follows:

Thickness Method The thickness of the soluble fibrous structure or film is such that each sample has a larger dimension than the load foot loading surface of the VIR Electronic Thickness Tester Model II (available from Thwing- Albert Instrument Company, Philadelphia, PA). It is measured by cutting out 5 samples from a sample of soluble fibrous structure or film. Typically, the load foot mounting surface has a circular surface area of about 20.26 cm ² (about 3.14 in ² ). Fix the sample between the horizontal plane and the load foot mounting surface. The load foot mounting surface applies a sealing pressure of 15.5 g/cm ² to the sample. The thickness of each sample is the gap created between the flat surface and the load foot mounting surface. Thickness is calculated as the average thickness of 5 samples. Results are reported in millimeters (mm).

Basis Weight Test Method The basis weight of a fibrous structure sample is measured by selecting 12 individual fibrous structure samples and making two stacks of 6 individual samples each. If the individual samples are connected to each other via perforation lines, the perforation lines must be aligned on the same side when stacking the individual samples. Using a precision cutter, cut each stack into exactly 8.9 cm x 8.9 cm (3.5 in x 3.5 in) squares. The two cut square stacks are combined to make 12 square thickness basis weight pads. After that, the basis weight pad is weighed with the above-mentioned balance with the minimum resolution of 0.01 g. The top balance must use draft shields to protect it from airflow and other obstructions. When the reading on the upper balance is constant, record the weight. Calculate basis weight as follows:

If the fibrous structure sample is smaller than 3.5 inches x 3.5 inches (8.89 cm x 8.89 cm), a narrower sampling area may be used for weighing determination, in connection with the change in calculation.

Weight Average Molecular Weight Test Method The weight average molecular weight (Mw) of a material (eg, polymer) is determined by gel permeation chromatography (GPC) using a mixed bed column. The following components: Millenium®, Model 600E pump, system controller and controller software version 3.2, Model 717 Plus autosampler, and CHM-009246 column heaters (all from Waters Corporation (Milford, MA, USA)). A high performance liquid chromatograph (HPLC) is used. The column is a PL gel 20 μm mixed A column (gel molecular weight: 1,000 g/mol to 40,000,000 g/mol) having a length of 600 mm and an inner diameter of 7.5 mm, and the guard column has a length of 50 mm and an ID of 7.5 mm. PL gel of 20 μm. The column temperature is 55° C. and the injection volume is 200 μL. The detector was a DAWN (comprising a Astra® software from Wyatt Technology (Santa Barbara, CA, USA), version 4.73.04 detector software, a laser light scattering detector with a K5 cell and a 690 nm laser ( (Registered trademark) Enhanced Optical System (EOS). The gain of the detector with an odd number is set to 101. The even gained detector gain is set to 20.9. The Wyatt Technology Optilab® differential refractometer is set at 50°C. Set the gain to 10. The mobile phase is HPLC grade dimethylsulfoxide containing 0.1% w/v LiBr and the mobile phase flow rate is 1 mL/min, isocratic. The execution time is 30 minutes.

Samples are prepared by dissolving the material in the mobile phase, nominally 3 mg of material per mL of mobile phase. The sample is capped and then stirred using a magnetic stirrer for about 5 minutes. The sample is then placed in a convection oven at 85°C for 60 minutes. The sample is then allowed to cool to room temperature. The sample is then filtered through a 5 mL syringe through a 5 μm nylon membrane (type: Spartan-25, Schleicher & Schuell (Keene, NH, USA)) and placed in a 5 milliliter (mL) autosampler vial.

For each series of measurement samples (3 or more samples of material), the blank sample solvent is injected into the column. Then, a check sample is prepared in the same manner as the method for the above sample. The check sample contains 2 mg/mL pullulan (Polymer Laboratories) having a weight average molecular weight of 47,300 g/mol. Analyze check samples before analyzing each sample set. Testing of blank samples, check samples, and material test samples is done in duplicate. A blank sample is used for the final measurement. The light scattering detector and the differential refractometer are “Dawn EOS Light Scattering Instrument Hardware Manual” and “Optilab® DSP Interferometric CA Bacterium, Harbour, Manual, Harvard, Manual, Wr. , Both incorporated herein by reference).

The detector software is used to calculate the weight average molecular weight of the sample. A dn/dc (differential change in refractive index with concentration) value of 0.066 is used. The baselines of the laser photodetector and the refractive index detector are corrected to eliminate detector dark current and solvent scattering interference. If the laser photodetector signal is saturated or exhibits excessive noise, its value is not used in the calculation of molecular mass. The regions for molecular weight characterization are selected such that the 90° detector signals for laser light scattering and refractive index are both greater than three times their respective baseline noise levels. The high molecular weight side of the chromatogram is typically limited by the refractive index signal and the low molecular weight side is limited by the laser light signal.

The weight average molecular weight can be calculated using the "first order Zimm plot" defined in the detector software. If the weight average molecular weight of the sample is greater than 1,000,000 g/mol, then both the first and second order Zimm plots are calculated and the least error result of the regression fit is used to calculate the molecular mass. The weight average molecular weight reported is the average of two runs of the material test sample.

Tensile Test Method: Elongation, Tensile Strength, TEA, and Modulus Using a load cell whose measured force is within 10%-90% of the cell's limit, a constant speed extensional tensile tester with computer interface (preferred Instrument measures elongation, tensile strength, TEA, secant modulus, and tangent modulus at the MTS Insight using Testworks 4.0 Software, available from MTS Systems Corp. (Eden Prairie, MN). To do. Both the movable (upper) pneumatic grip and the fixed (lower) pneumatic grip are fitted with rubber-lined grips with a height of 25.4 mm and wider than the width of the test piece. Air pressure of about 0.6 MPa (80 psi) is supplied to the jaws. All tests are conducted in a conditioned room maintained at about 23°C ± 1°C and relative humidity of about 50% ± 2%. Samples are conditioned for 2 hours under the same conditions before testing.

Eight specimens of soluble and/or soluble fibrous structure are divided into two stacks of four specimens each. The test specimens in each stack are consistently oriented in the machine direction (MD) and the transverse direction (CD). One of the stacks is for MD testing and the other is for CD testing. Using a 2.54 cm (1 inch) precision cutter (such as the Thwing Albert JDC-1-10), 4 MD strips from one stack and 4 CD strips from the other stack (2.54 cm±0. Cut a width of 02 cm x a length of at least 50 mm).

The tensile tester is programmed to perform an extension test and force and extension data are collected at an acquisition rate of 100 Hz. First, lower the crosshead by 6 mm at a speed of 5.08 cm/min to loosen the test piece, and then raise the crosshead at a speed of 5.08 cm/minute until the test piece breaks. The breaking sensitivity is set to 80%. That is, the test ends when the measured force drops to 20% of the maximum peak force, after which the crosshead returns to its initial position.

Set the gauge length to 2.54 cm. Zero the crosshead. Insert the test strip into the upper grip, align it vertically within the upper and lower grips, and close the upper grip. With the sample hanging from the upper grip, zero the load cell. Insert the test piece into the lower grip and close. With the grip closed, the test specimen should be under sufficient tension to completely eliminate slack, but less than 3.0 g force on the load cell. Start the tensile tester and start data collection. The test is similarly repeated for all four CD and four MD test pieces.

Program the software to calculate the following from the force (g) versus extension (cm) curves constructed:
Tensile strength is the maximum peak force (g) divided by the width (cm) of the test piece and is reported as 1.0 g/cm in g/cm.

The adjusted gauge length is calculated as the extension measured when 3.0 g of force (cm) is applied to the original gauge length (cm).

Elongation is calculated as the elongation at maximum peak force (cm) divided by the adjusted gauge length (cm) and multiplied by 100 and is reported as a% in 0.1% units.

The total energy (TEA) was the area under the force curve (g ^* cm) integrated from zero extension to extension at maximum peak force divided by the product of the adjusted gauge length (cm) and the width of the specimen (cm). Calculated as and reported in units of 1 g ^* cm/cm ² .

The force (g) versus extension (cm) curve is re-plotted as the force (g) versus strain (%) curve. Strain herein is defined as the extension (cm) divided by the adjusted gauge length (cm) times 100. The software is programmed to calculate the following from the force (g) vs. strain (%) curve constructed:

The secant modulus is calculated from the least-squares linear fit of the steepest slope of the force to strain curve, with the code increasing at least 20% of the peak force. This slope is then divided by the width of the specimen (2.54 cm) and reported in 1.0 g/cm units.

The tangent modulus is calculated as the slope of the line drawn between two data points in the force (g) vs. strain (%) curve. The first data point used is the point recorded with a force of 28 g and the second data point used is the point recorded with a force of 48 g. This slope is then divided by the width of the specimen (2.54 cm) and reported in 1.0 g/cm units.

Tensile strength ((N/m (g/cm)), elongation (%), total energy (g ^* cm/cm ² ), secant modulus (g/cm), and tangent modulus (g/cm) were set to 4 Calculate for one CD specimen and four MD specimens: For CD and MD specimens, calculate the mean of each parameter separately.

Calculation:
Total dry tensile strength (TDT) = MD tensile strength (g/cm) + CD tensile strength (g/cm)
Geometric mean tensile strength = square root of [MD tensile strength (g/cm) x CD tensile strength (g/cm)] Tensile ratio = MD tensile strength (g/cm)/CD tensile strength (g/cm)
Geometric mean peak elongation=square root of [MD elongation (%)×CD elongation (%)] Total TEA=MD TEA (g ^* cm/cm ² )+CD TEA (g ^* cm/cm ² ).
Square root of geometric mean TEA=[MD TEA (g ^* cm/cm ² )×CD TEA (g ^* cm/cm ² )] Geometric mean tangent modulus=[MD tangent modulus (g/cm)×CD tangent modulus (g/ cm)] total tangent modulus = MD tangent modulus (g/cm) + CD tangent modulus (g/cm)
Geometric mean secant modulus = square root of [MD secant modulus (g/cm) x CD secant modulus (g/cm)] Total secant modulus = MD secant modulus (g/cm) + CD secant modulus (g/cm)

Plate Stiffness Test Method As used herein, the “plate rigidity” test is a measurement of the rigidity of a flat sample as it deforms downward into a hole directly beneath the sample. For testing, the sample is modeled as an infinite plate with thickness "t", which lies on a flat surface placed on the center of a hole of radius "R". The central force "F" applied to the tissue directly over the center of the hole causes the tissue to bend downward into the hole by a distance "w". For linear elastic materials, the refraction can be predicted by the formula:

式中、「Ｅ」は、有効線形弾性率であり、「ｖ」は、ポワソン比であり、「Ｒ」は、穴の半径であり、「ｔ」は、約１９９９．４８Ｐａ（０．２９ｐｓｉ）の負荷下、５枚のティッシュからなるスタック上で測定される厚さ（ミリメートル）として測定される、ティッシュの厚みである。ポワソン比を０．１とすると（溶液は、このパラメーターに対して高度に感受性ではないので、仮定値による誤差は小さい可能性が高い）、前述の等式は、可撓性試験結果の関数として有効弾性率を推定するために「ｗ」を書き換えることができる：

Where "E" is the effective linear modulus, "v" is the Poisson's ratio, "R" is the radius of the hole, and "t" is about 1999.48 Pa (0.29 psi). Is the thickness of the tissue, measured as the thickness in millimeters measured on a stack of 5 tissues under a load of. Given a Poisson's ratio of 0.1 (the solution is not highly sensitive to this parameter, the error due to the hypothesis is likely to be small), the above equation becomes a function of the flexibility test results. The "w" can be rewritten to estimate the effective modulus:

The test results are carried out on a MTS Alliance RT/1 tester (MTS Systems Corp., Eden Prairie, Minn.) using a 100N load cell. A stack of five tissue sheets of at least 16.1 square centimeters (2.5 square inches) square was placed on the center of a 15.75 mm radius hole on the backing plate and a 3.15 mm radius blunt probe at 20 mm/min. At the speed of. The test is terminated when the tip of the probe drops 1 mm below the surface of the support plate. The maximum slope (force (g)/mm) over any 0.5 mm total length is recorded during the test (this maximum slope generally occurs at the end of the stroke). The load cell monitors the applied force and also the position of the probe tip relative to the surface of the support plate. Record peak load and estimate "E" using the above equation.

The plate stiffness "S" per unit width can then be calculated as follows:

ニュートン−ミリメートルの単位で表される。試験作業プログラムは、以下の式を使用して剛性を計算する：
Ｓ＝（Ｆ／ｗ）［（３＋ｖ）Ｒ²／１６π］
式中、「Ｆ／ｗ」は、最大傾斜（歪みで除した力）であり、「ｖ」は、０．１としたポワソン比であり、「Ｒ」は、輪の半径である。

Newton-expressed in millimeters. The test work program calculates stiffness using the following formula:
S=(F/w)[(3+v)R ² /16π]
In the equation, “F/w” is the maximum inclination (force divided by strain), “v” is the Poisson's ratio of 0.1, and “R” is the radius of the ring.

Fiber Element Composition Test Method Fiber element composition is prepared by removing any removable coating composition and/or material present on the outer surface of the fiber element to prepare the fiber element for measurement. Adjust. The chemical analysis of the conditioned fibrous element is then completed to determine the composition of the fibrous element with respect to the fibrous element forming material and activator, as well as the concentration of fibrous element forming material and activator present in the fibrous element.

Further, the compositional constitution of the fiber element regarding the fiber element forming material and the activator may be obtained by completing the cross-sectional analysis using TOF-SIM or SEM. Yet another method for determining the compositional composition of a fiber element is to use fluorescent dyes as markers. Moreover, as a rule, fiber element manufacturers must be aware of the composition of their fiber elements.

Median Particle Size Test Method This test method must be used to determine the average particle size.

The median grain of seed material using ASTM D 502-89, "Standard Test Method for Particle Size of Soaps and Other Detergents", approved on May 26, 1989, and the size of the sieves used for analysis. A median particle size test is performed to measure the diameter. In accordance with the “Procedure using machine-sieving method” of the seventh paragraph, American Standard (ASTM E11) sieve #8 (2360 um), #12 (1700 um), #16 (1180 um), #20 (850 um), #30 (600 um). , #40 (425um), #50 (300um), #70 (212um), #100 (150um). The above-mentioned nested sieves are used for the defined mechanical sieving method. The seed material is used as a sample. A suitable sieve vibrator is W. S. Tyler Company (Mentor, Ohio, USA).

The micrometer opening size of each sieve was plotted on a logarithmic abscissa, cumulative mass percent (Q ₃₎ on a semi-logarithmic plot, plotted on a linear ordinate plots the data. An example of the above data representation is ISO A 2766-1:1998, "Representation of results of particle size analysis-Part 1: Graphic Representation", A. 4 are described. For the purposes of this invention, the median particle size (D ₅₀ ) of the seed material is defined as the abscissa value at the point where the cumulative weight percent is equal to 50 percent, just above the 50% value using the following equation: It is calculated by linear interpolation between the data points of (a50) and directly below (b50).
_{D 50 = 10 ^ [Log (} D a50) - (Log (D a50) -Log (D b50)) * (Q a50 -50%) / (Q a50 -Q b50)]
_Where Q _a50 and Q _b50 are the cumulative mass percentile values of the data just above and below the 50 th percentile value, respectively, and D _a50 and D _b50 are the micrometer sieve size values corresponding to these data. ).

If the 50th percentile value is smaller than the finest sieve size (150um) or larger than the coarsest sieve size (2360um), a median ratio of 1.5 or less until the median falls between the two measured sieve sizes. Additional sieves must be added to the nest according to series.

The seed substance distribution Span is a measure of the full width of the seed size distribution with respect to the median (median particle size). It is calculated according to the following:
Span=(D ₈₄ /D ₅₀ +D ₅₀ /D ₁₆ )/2
Where D ₅₀ is the median particle size and D ₈₄ and D ₁₆ are the particle size at the 16th and 84th percentile values on the cumulative weight percent plot, respectively.

If the D ₁₆ value is smaller than the finest sieve size (150 um), the Span is calculated according to the following:
Span=(D ₈₄ /D ₅₀ ).

If the D ₈₄ value is larger than the coarsest sieve size (2360 um), the Span is calculated according to the following:
Span=(D ₅₀ /D ₁₆ ).

If the D ₁₆ value is smaller than the finest sieve size (150 um) and the D ₈₄ value is larger than the coarsest sieve size (2360 um), the distribution Span is set to the maximum value of 5.7.
