For example, a cross section having a rectangle formed by two opposite side “A” and two opposite side “B” can be expressed as S = A × B. At the same time, this cross-sectional area can be expressed as the area of a circle having an equivalent diameter D. The equivalent diameter D can then be calculated from the equation S = 1 / 4πD ² , where S is a known area of the rectangle. (It goes without saying that the equivalent diameter of a circle is the true diameter of the circle.) The equivalent radius is ½ of the equivalent diameter.

  “Pseudo-thermoplastic” with respect to “material” or “composition” can be softened to the extent that it can be made flowable by effects such as dissolution at high temperature, in a suitable solvent, or otherwise. And is intended to represent materials and compositions that can be shaped as desired in this condition and more specifically processed to form starch filaments suitable for the formation of fibrous structures. The pseudo-thermoplastic material can be formed, for example, under the influence of a combination of heat and pressure.

Does not "melt" so if they are not present, any temperature or pressure cannot produce the soft or flowable properties necessary for molding. The effect of water content on the glass transition temperature and melting temperature of starch is described by Zeleznak and Hoseny in “Cereal Chemistry”, Vol. 64, no. 2, pp. 121-124, 1987. It can be measured by the suggested scanning calorimetry. The pseudo thermoplastic resin melt is a pseudo thermoplastic material in a fluid state.

  “Microfeatures” and their permutations, in contrast to the overall (ie, “macroscopic”) shape, do not take into account the overall shape of the structure, and are relatively small (ie, , Microscopic) refers to details (eg surface texture). The term “macroscopic” or “macroscopic” refers to the overall shape of a structure or a portion thereof, when considered in a two-dimensional arrangement such as an XY plane. For example, on a macroscopic level, a fibrous structure includes a relatively thin and flat sheet when placed on a flat surface. However, at a microscopic level, the structure is distributed across the plurality of first regions forming a first plane having a first height, the entire framework region, and extends outward from the framework region. A plurality of domes or "pillars" forming a second height.

  “Intensity” is a characteristic that does not have a value corresponding to a set of values in the plane of the fibrous structure. A common strength is a strength possessed by two or more regions. Such strength of the fibrous structure includes, but is not limited to, density, basis weight, height, and opacity. For example, if the density is a common strength of two specific regions, the density value in one region may be different from the density value in the other region. Regions (e.g., first region and second region, etc.) are identifiable areas that can be distinguished from each other by distinctive intensities.

“Glass transition temperature” T _g is the temperature at which a substance changes from a viscous or rubbery state to a hard and relatively brittle state.

  The “machine direction” (or MD) is the direction parallel to the flow of the fibrous structure produced by the production equipment. The “width direction” (or CD) is the direction perpendicular to the machine direction and parallel to the general plane of the fibrous structure to be produced.

  “X”, “Y”, and “Z” indicate a normal Cartesian coordinate system, coordinates “X” and “Y” perpendicular to each other define a reference XY plane, and “Z” is X— Define orthogonality to the Y plane. The “Z direction” indicates an arbitrary direction perpendicular to the XY plane. Similarly, the term “Z dimension” means a dimension, distance, or parameter measured parallel to the Z direction. For example, if an element such as a molded member is curved or otherwise non-planar, the XY plane follows the shape of this element.

  A “substantially continuous” region refers to an area that can connect any two points with a line that is not interrupted over the entire length of the line through the entire area. That is, the substantially continuous region has substantial “continuity” in all directions parallel to the first plane and terminates only at both ends of the region. The term “substantially” with respect to continuity is preferably absolute continuity, but minor deviations from absolute continuity are evident in the design and performance of the intended fibrous structure (or molded part) It is intended to show that these deviations are acceptable unless they have an impact.

  A “substantially semi-continuous” region is an area that has “continuity” in all directions except at least one direction parallel to the first plane, and is uninterrupted over the entire length of the line through the entire area. This refers to the area where any two points cannot be connected. A semi-continuous framework can have continuity only in one direction parallel to the first plane. Similar to the continuous region described above, absolute continuity in all directions except at least one direction is preferred, as long as minor deviations from absolute continuity do not clearly affect the performance of the fibrous structure. These deviations are acceptable.

  A “discontinuous” region refers to discrete areas that are discrete and discontinuous in all directions parallel to the first plane.

  “Flexibility” is the ability to deform a material or structure without breaking it under a given load, regardless of whether the material or structure can or cannot return to its original shape.

A structural element that can be used as a forming unit. Molded members can include any element that has the ability to impart a three-dimensional pattern to the structure produced thereon, including fixed plates, belts, cylinders / rolls, woven fabrics, and bands. It is not limited.

  “Melt spinning” is the process of using a damping force to convert a thermoplastic or pseudo-thermoplastic material into a fiber material. Melt spinning can include mechanical stretching, melt blowing, spunbonding, and electrospinning.

  “Mechanical stretching” is the process of inducing a force on a fiber yarn, which produces the fiber by contacting the fiber yarn with a driven surface, such as a roll, and applying force to the melt.

  “Melt blowing” is the process of producing a fibrous web or article directly from a polymer or resin using high velocity air or another suitable force to reduce the filament diameter. In the meltblowing process, the damping force is applied in the form of a high velocity wind as the material exits the die or spinneret.

  “Spunbonding” involves the process of applying a force through a high velocity air source or another suitable source after the fibers have been dropped a predetermined distance under flow force and gravity.

  “Electrospinning” is a process that uses an electric potential as a force to reduce the diameter of a fiber.

  “Dry spinning”, commonly known as “solution spinning”, involves the use of solvent drying to stabilize fiber formation. The material is dissolved in a suitable solvent and reduced in diameter by mechanical stretching, melt blowing, spunbonding, and / or electrospinning. The fibers become stable as the solvent evaporates.

  “Wet spinning” involves dissolving the material in a suitable solvent and forming fibrils by mechanical stretching, melt blowing, spunbonding, and / or electrospinning. Once the fibers are formed, they are poured into a coagulation system that typically includes a bath filled with a suitable solution that solidifies the desired material to produce stable fibers.

  “Melting temperature” means a temperature range at or above which the starch composition can sufficiently melt or soften to process starch filaments. It should be understood that some starch compositions are pseudo-thermoplastic compositions and therefore cannot exhibit pure “melting” behavior as such.

  “Processing temperature” means the temperature of the starch composition at which starch filaments can be formed, for example, by reducing the diameter.

  As used herein, “basis weight” is the weight per unit area of a sample reported in gsm and is measured according to the basis weight test method described herein.

  As used herein, “fibrous structure” means a structure comprising one or more fiber filaments and / or fibers. In one example, a fibrous structure refers to an ordered arrangement of filaments and / or fibers within the structure to perform a function. Non-limiting examples of fibrous structures can include detergent products, fabrics (such as wovens, knitted fabrics, and nonwovens), and absorbent pads (eg, for diapers or feminine hygiene products). The fibrous structure of the present invention may be homogeneous or layered. When layered, the fibrous structure has at least 2, and / or at least 3, and / or at least 4, and / or at least 5 layers (eg, one or more layers of fiber elements, one or more And / or one or more fiber elements / particle mixed layers).

  As used herein, the articles “a” and “an” are used herein, for example, “an anionic surfactant” or “a fiber”. In the case, it is understood that it means that one or more of the claimed or described substances.

  All percentages and ratios are calculated by weight unless otherwise indicated. All percentages and ratios are calculated based on the total composition unless otherwise indicated.

  Unless otherwise stated, all concentrations of a component or composition relate to the activity level of that component or composition and exclude impurities that may be present in commercial sources, such as residual solvents or by-products. Is done.

The second region of the fibrous structure 20 may include a plurality of individual zones 24 that are dispersed throughout the network region 22, essentially each individual zone being surrounded by the network region 22. The shape of the individual zones 24 can be defined by the mesh region 22. As shown in FIG. 4, the individual zones 24 appear to extend (protrude) from the plane formed by the mesh region 22 toward the virtual observer looking in the direction of the arrow T. When viewed by a virtual observer looking in the direction indicated by arrow B in FIG. 4, the second region includes an arcuate void that appears to be a cavity or a depression.

iii. Perfume delivery systems Specific perfume delivery systems, methods of making specific perfume delivery systems, and the use of such perfume delivery systems are disclosed in US Patent Application Publication No. 2007/0275866. Non-limiting examples of perfume delivery systems include the following:
Polymer Assisted Delivery (PAD): This perfume delivery technique uses a polymer material to deliver a perfume substance. Classical coacervation, water-soluble or partially water-soluble to insoluble charged or neutral polymers, liquid crystals, hot melts, hydrogels, perfumed plastics, microcapsules, nano- and microlatexes, polymer film formers, polymer absorption Agents, polymer adsorbents, etc. are some examples. PADs include, but are not limited to:

  a. ) Matrix system: A fragrance is dissolved or dispersed in a polymer matrix or particles. The perfume may be, for example, 1) dispersed in the polymer before blending into the product, or 2) added separately from the polymer during or after blending the product. Perfume diffusion from the polymer is a common incentive to allow or increase the release rate of a perfume from a polymer matrix system that has been accumulated or applied to the desired surface (site). Many other triggers that can control the release of are known. Absorption and / or adsorption into or outside polymer particles, films, solutions, etc. is an aspect of this technique. Examples are nano- or microparticles made of organic materials (eg latex). Suitable particles include, but are not limited to, polyacetal, polyacrylate, polyacrylic, polyacrylonitrile, polyamide, polyaryletherketone, polybutadiene, polybutylene, polybutylene terephthalate, polychloroprene, polyethylene, polyethylene terephthalate, Polycyclohexylenedimethylene terephthalate, polycarbonate, polychloroprene, polyhydroxyalkanoate, polyketone, polyester, polyethylene, polyetherimide, polyethersulfone, polyethylene chlorinate, polyimide, polyisoprene, polylactic acid, polymethylpentene, polyphenylene oxide, Polyphenylene sulfide, polyphthalamide, polypropylene, polystyrene, poly Wide range of polymers or copolymers based on luphone, polyvinyl acetate, polyvinyl chloride, and acrylonitrile-butadiene, cellulose acetate, ethylene-vinyl acetate, ethylene vinyl alcohol, styrene-butadiene, vinyl acetate-ethylene, and mixtures thereof Materials.

  A “standard” system refers to one that is “pre-filled” with the intention of holding the pre-filled perfume attached to the polymer until the moment of perfume release. Such polymers can suppress the odor of undiluted products and can also provide bloom and / or lasting effects depending on the release rate of the perfume. One of the challenges in these systems is to achieve an ideal balance between 1) in-product stability (holding the fragrance inside the carrier until needed) and 2) timely release (during use or from the dry site). It is to be. The realization of such stability is particularly important during storage in the product and during product aging. This problem is particularly evident in water based surfactant-containing products such as strong liquid laundry detergents. Many of the “standard” matrix systems available are effectively “equilibrium” systems when formulated into water-based products. “Equilibrium” or reservoir systems can be selected that have acceptable in-product diffusion stability and available release incentives (eg, friction). An “equilibrium” system is one in which the perfume and polymer can be added separately to the product, and the equilibrium interaction between the perfume and the polymer causes an effect at one or more consumer contact points (as opposed to , Free perfume control does not have polymer-assisted delivery technology). This polymer can also be pre-filled with a perfume, but some or all of the perfume may diffuse during storage in the product and reach an equilibrium state where the desired perfume raw material (PRM) is bound to the polymer. The polymer then transports the perfume to the surface and typically releases as the perfume diffuses. The use of such equilibrium polymers has the potential to reduce the undiluted product odor intensity of the undiluted product (usually particularly so in the case of pre-filled standard systems). Such polymer accumulation can “flatten” the release profile and increase persistence. As indicated above, such persistence is obtained by suppressing the initial strength, allowing the formulator to use a higher impact or lower olfactory threshold (ODT) or lower Kovats index (KI) PRM, The FMOT effect can be obtained without the initial strength being too strong or changing. In order to affect the desired consumer contact point, it is important that perfume release occurs within the time frame of application. Suitable microparticles and microlatexes and methods for their production can be found in US Patent Application No. 2005/0003980 (A1). The matrix system also includes hot melt adhesives and aromatic plastics. In addition, hydrophobically modified polysaccharides can be incorporated into perfume products to increase perfume accumulation and / or modify perfume release. All such matrix systems such as polysaccharides and nanolatex can be combined with other PDTs including other PAD systems such as PAD reservoir systems to form perfume microcapsules (PMC). Polymer-assisted delivery (PAD) matrix systems include those described in the following references: US Patent Application Publication Nos. 2004/0110648 (A1), 2004/0092414 (A1), 2004. No./0091445 (A1) and 2004/0087476 (A1), and US Pat. Nos. 6,531,444, 6,024,943, 6,042,792, No. 051,540, No. 4,540,721, and No. 4,973,422.

  An example of a polymer that can be used as a PDT is silicone, which provides a perfume effect in the same way as a polymer-assisted delivery “matrix system”. Such PDT is called silicone-assisted delivery (SAD). Silicone can be pre-filled with a fragrance or the silicone can be used as an equilibrium system as described for PAD. Suitable silicones and methods for their production are described in WO 2005/102261, US Patent Application Publication No. 2005/0124530 (A1), US Patent Application Publication No. 2005/0143282 (A1), and WO 2003/015736. Can be found in the issue. It is also possible to use silicones functionalized as described in patent application 2006/003913 (A1). Examples of silicone include polydimethylsiloxane and polyaldimethylsiloxane. Other examples include those with amine functionality that can be used to relate to amine assisted delivery (AAD) and / or polymer assisted delivery (PAD) and / or amine reaction products (ARP). Can give an effect. Other such examples are disclosed in U.S. Patent No. 4,911,852, U.S. Patent Application Nos. 2004/0058845 (A1), 2004/0092425 (A1), and 2005/0003980 (A1). Can be found.

  b. ) Reservoir system: The reservoir system is also known as core / shell type technology, ie a technology in which the fragrance is surrounded by a perfume release control membrane that can function as a protective shell. The material inside the microcapsule is called the core, internal phase, or filler, whereas the wall is sometimes called the shell, coating, or membrane. Microparticles, or pressure sensitive capsules, or microcapsules are examples of such techniques. The microcapsules of the present invention are formed by various methods including, but not limited to, coating, extrusion, spray drying, interfacial polymerization, in situ polymerization, and matrix polymerization. Usable shell materials vary greatly in water stability. Most stable are polyoxymethylene urea (PMU) based materials that can retain a particular PRM in an aqueous solution (or product) for a longer period of time. Such systems include, but are not limited to, urea-formaldehyde and / or melamine-formaldehyde. Stable shell materials include oil-soluble or dispersible amines and multifunctional acrylate or methacrylate monomers or oligomers in the presence of an anionic emulsifier containing a water-soluble or water-dispersed alkyl acrylate copolymer, alkali, or alkali salt. And polyacrylate materials obtained as a reaction product of an oil-soluble acid and a reaction initiator. For example, gelatin-based microcapsules may be prepared so as to dissolve quickly or slowly in water according to the degree of crosslinking. Many other capsule wall materials are available and differ in the degree of perfume diffusion stability observed. Without being bound by theory, for example, the release rate of perfume from a capsule once attached to the surface is typically the inverse order of perfume diffusion stability within the product. For this reason, urea-formaldehyde and melamine-formaldehyde microcapsules, for example, typically break capsules and increase the release rate of fragrances (fragrances), such as mechanical forces (eg, friction, pressure, shear stress). Increased, non-diffusion (in addition to diffusion) release mechanisms are required for perfume release. Other triggers include melting, dissolution, hydrolysis, or other chemical reactions, electromagnetic radiation, and the like. The use of pre-filled microcapsules requires an appropriate selection of PRMs in addition to the proper ratio of in-product stability and on-use and / or on-surface (on-site) release. Microcapsules based on urea-formaldehyde and / or melamine-formaldehyde are relatively stable, especially in aqueous solutions close to neutrality. These materials may require friction incentives, which are not applicable to all product applications. Other microcapsule materials (eg, gelatin) may be unstable in aqueous products and may be less effective when aging within the product (for free fragrance control). The scent (scratch and sniff) technique when rubbed is yet another example of PAD. Perfume microcapsules (PMCs) may include those described in the following references: US Patent Publication Nos. 2003/0125222 (A1), 2003/215417 (A1), 2003/216488 ( A1), 2003/158344 (A1), 2003/1665692 (A1), 2004/071742 (A1), 2004/071746 (A1), 2004/072719 (A1) A1), 2004/072720 (A1), 2006/0039934 (A1), 2003/203829 (A1), 2003/195133 (A1), 2004/087477 ( A1), 2004/0106536 (A1), and US Pat. No. 6,645,479 (B1). No. 6,200,949 (B1), No. 4,882,220, No. 4,917,920, No. 4,514,461, No. 6,106,875, 4,234,627, 3,594,328, and US RE 32713, PCT patent applications: International Publication Nos. 2009/134234 (A1), 2006/127454 (A2), 2010/0779466 (A2), 2010/0779467 (A2), 2010/0779468 (A2), 2010/084480 (A2).

  Molecular Assisted Delivery (MAD): Non-polymeric substances or molecules can also function to improve perfume delivery. Without being bound by theory, fragrances may interact non-covalently with organic materials to alter adhesion and / or release. Non-limiting examples of such organic materials include, but are not limited to, hydrophobic materials such as organic oils, waxes, mineral oils, petrolatum, fatty acids, or esters, saccharides, surfactants, liposomes, and more Other perfume raw materials (perfume oils) and natural oils such as the body and / or other soils. A perfume fixing agent is yet another example. In one aspect, the non-polymeric material or molecule has a CLogP value greater than about 2. Molecular assisted delivery (MAD) can further include those described in US Pat. Nos. 7,119,060 and 5,506,201.

  Fiber Assisted Delivery (FAD): Site selection or use may itself improve perfume delivery. Indeed, the site itself can be a perfume delivery technique. For example, different types of fabrics such as cotton or polyester have different properties with respect to their ability to attract and / or retain and / or release perfume. The amount of perfume that accumulates on or in the fiber can vary depending on the choice of fiber, and also by fiber history or treatment, as well as by any fiber coating or treatment. The fiber may be woven or non-woven, and may be natural or synthetic. Natural fibers include those made by plant, animal, and geological processes, including cotton, linen, burlap, flax, ramie, sisal, and fibers used in the manufacture of paper and fabric. It is not limited. Fiber assisted delivery may consist of the use of wood fibers such as thermomechanical pulp, bleached or unbleached kraft, or sulfite pulp. Animal fibers are mainly composed of specific proteins such as silk, tendon, intestinal line, and hair (such as wool). Polymer fibers based on synthetic chemicals include, but are not limited to, polyamide nylon, PET or PBT polyester, phenol-formaldehyde (PF), polyvinyl alcohol fiber (PVOH), polyvinyl chloride fiber (PVC), polyolefin (PP and PE), and acrylic polymers. All of these fibers can be pre-filled with perfume and then added to products that may or may not include free perfume and / or one or more perfume delivery technologies. In one aspect, the fibers may be filled with the fragrance by adding the fibers to the product prior to filling with the fragrance and then adding to the product a fragrance that can diffuse into the fibers. Without being bound by theory, the perfume can be absorbed onto the fiber surface or adsorbed inside the fiber during product storage, for example, and later released at one or more critical moments or consumer contact points.

  Amine Assisted Delivery (AAD): Amine assisted delivery technology approaches increase the perfume accumulation by using materials containing amine groups and modify the perfume release during product use. In this method, it is not necessary to combine or react the fragrance raw material and the amine in advance prior to addition to the product. In one aspect, suitable amine-containing AAD materials for use herein are non-aromatic such as polyalkylimines such as polyethyleneimine (PEI) or polyvinylamine (PVAm), or, for example, anthranilate. It may be aromatic. Such materials may be polymeric or non-polymeric. In one aspect, such materials include at least one primary amine. This technology increases the persistence of low ODT fragrances (eg, aldehydes, ketones, enones) and allows controlled release by the functionality of the amine, and is not bound by theory. It enables delivery of other PRMs by polymer assisted delivery. Without this technique, volatile top notes are lost too early, resulting in a high ratio of middle and reference notes to top notes. Can the use of polymer amines allow the freshness to persist so that the odor of the undiluted product does not become stronger than ideal by using higher concentrations of top notes and other PRMs, Alternatively, top notes and other PRMs can be used more efficiently. In one aspect, the AAD system effectively delivers PRM at a higher pH than near neutrality. Without being bound by theory, under the conditions in which more amines of the AAD system are deprotonated, deprotonation for PRMs such as unsaturated ketones and aldehydes and ketones including enones such as damascene. There is a possibility that the affinity of the oxidized amine is increased. In another aspect, the polymeric amine effectively delivers PRM at a pH lower than near neutral. Without being bound by theory, under conditions in which more amines of the AAD system are protonated, the affinity of the protonated amine for PRMs such as aldehydes and ketones is reduced, resulting in a wide range of PRMs. May have a higher affinity for the polymer backbone. In such embodiments, higher perfume effects can be delivered by polymer-assisted delivery. That is, these systems fall under AAD and can be referred to as amine-polymer assisted delivery, or APAD. Such APAD systems can also be considered polymer assisted delivery (PAD), such as when using APAD in compositions with pH lower than 7. In yet another aspect, AAD and PAD systems interact with other materials such as anionic surfactants or polymers to form coacervates and / or coacervate-like systems. In another embodiment, materials containing heteroatoms other than nitrogen, such as sulfur, phosphorus, selenium, can be used in place of the amine compounds. In yet another aspect, the above alternative compounds can be used in combination with an amine compound. In yet another aspect, a molecule may have an amine moiety and one or more alternative heteroatom moieties such as thiol, phosphine, and selenol. A suitable AAD system and its production method are disclosed in US Patent Application Publication Nos. 2005/0003980 (A1), 2003/0199422 (A1), 2003/0036489 (A1), 2004/0220074 (A1). ) And US Pat. No. 6,103,678.

  Cyclodextrin delivery system (CD): This technical approach improves the delivery of perfume using cyclic oligosaccharides or cyclodextrins. Typically, it forms a complex of perfume and cyclodextrin (CD). Such a complex may be preformed, formed in situ, or formed on or within the surface of the site. Without being bound by theory, it is in equilibrium due to loss of water, especially when other auxiliary ingredients (eg, surfactants) are not present at such high concentrations that they compete for the perfume and cyclodextrin lumen. Can move to the CD-fragrance complex side. If there is contact with water or an increase in water content at a later time, the Bloom effect may be obtained. Furthermore, the cyclodextrin increases the flexibility of the choice of PRM by the fragrance formulator. The cyclodextrin may be pre-filled with a perfume or added separately from the perfume to obtain the desired perfume stability, accumulation, or release effect. Suitable CDs and methods for their production are described in U.S. Patent Application Publication Nos. 2005/0003980 (A1) and 2006/0263313 (A1), and U.S. Pat. Nos. 5,552,378 and 3,812. No. 011, No. 4,317,881, No. 4,418,144, and No. 4,378,923.

  Starch Encapsulated Accord (SEA): Through the use of starch encapsulated accord (SEA) technology, it is possible to modify the perfume properties, for example, by adding ingredients such as starch to convert the liquid perfume into a solid. As the effect, the retention of the fragrance during product storage is improved particularly under non-aqueous conditions. On contact with moisture, a perfume bloom can be caused. Starch allows product formulators to select a PRM or concentration of PRM that would otherwise not be available in the absence of SEA, which may provide additional benefits at other critical moments. is there. An example of another technique is the use of other organic and inorganic materials such as silica to convert the perfume from a liquid to a solid. Suitable SEAs and methods for their production can be found in US Patent Application Publication No. 2005/0003980 (A1) and US Pat. No. 6,458,754 (B1).

  Inorganic carrier delivery system (ZIC): This technology relates to the use of porous zeolites or other inorganic materials to deliver perfume. Perfume-filled zeolite can be used, for example, with or without other auxiliary ingredients used to coat perfume-filled zeolite (PLZ), during product storage or use, or from dry sites It is possible to change the perfume release characteristics of Suitable zeolites and inorganic carriers and methods for their production are described in US Patent Application Publication No. 2005/0003980 (A1) and US Pat. Nos. 5,858,959, 6,245,732 (B1), Nos. 6,048,830 and 4,539,135. Silica is another form of ZIC. Another example of a suitable inorganic carrier is an inorganic tube, in which a fragrance or other active substance is contained within the lumen of the nano or microtube. In one aspect, the perfume-filled inorganic tube (or perfume-filled tube or PLT) is a mineral nano- or micro-tube, such as halloysite or a mixture of halloysite and other inorganic materials (such as other clays). is there. PLT technology may include additional components on the inside and / or outside of the tube for the purpose of improving diffusion stability in the product, accumulation at the desired site, or controlling the release rate of the filled fragrance. . Monomers and / or polymer materials such as starch inclusions can be used to coat, plug, capping, or otherwise encapsulate the PLT. Suitable PLT systems as well as methods for their production can be found in US Pat. No. 5,651,976.

  Pro-perfume (PP): This technique reacts perfume materials with other substrates or chemicals to form a material with a covalent bond between one or more PRMs and one or more carriers. Perfume technology obtained from this. PRM is converted into a new material called pro-PRM (ie pro-perfume), which releases the original PRM when exposed to triggers such as water or light. Pro-perfumes can provide improved perfume delivery properties such as increased perfume accumulation, persistence, stability, retention. Pro-perfumes may be monomeric (non-polymeric) or polymeric, and the pro-perfumes may be preformed or equilibrated so that they can be present in the product or on wet or dry sites It may be formed in situ below. Non-limiting examples of pro-perfumes include Michael adducts (eg, beta-amino ketones), aromatic or non-aromatic imines (Schiff bases), oxazolidine, beta-keto esters, and ortho esters. Another embodiment includes compounds that contain one or more beta-oxy or beta-thiocarbonyl moieties capable of releasing PRM, such as alpha, beta-unsaturated ketones, aldehydes, or carboxyl esters. Typical incentives for releasing perfume are contact with water, but other incentives include enzymes, heat, light, pH changes, auto-oxidation, equilibrium shifts, changes in concentration or ionic strength, etc. Can do. For water based products, light-induced pro-perfumes are particularly suitable. Such light pro-perfumes (PPP) include, but are not limited to, those that release coumarin derivatives and perfumes and / or pro-perfumes upon induction. The released pro-perfume may release one or more PRMs by any of the triggers mentioned above. In one aspect, the light pro-perfume releases a nitrogen-based pro-perfume when exposed to light and / or moisture incentives. In another aspect, the nitrogen-based pro-perfume released from the light pro-perfume releases one or more PRMs selected from, for example, aldehydes, ketones (including enones), and alcohols. In yet another aspect, the PPP releases a dihydroxycoumarin derivative. The light-triggered pro-perfume may be an ester that releases a coumarin derivative and a perfume alcohol. In one aspect, the pro-perfume is a dimethoxybenzoin derivative described in US 2006/0020459 (A1). In another aspect, the pro-perfume is a 3 ', 5'-dimethoxybenzoin (DMB) derivative that releases alcohol when exposed to electromagnetic radiation. In yet another aspect, the pro-perfume releases one or more low ODT PRMs including tertiary alcohols such as linalool, tetrahydrolinalool, or dihydromyrcenol.

Typically, the reactive amine is a primary and / or secondary amine and can be part of a polymer or monomer (non-polymer). Such ARPs can also be mixed with additional PRMs to provide the effects of polymer assisted delivery and / or amine assisted delivery. Non-limiting examples of polymeric amines include polyalkylimines such as polyethyleneimine (PEI), or polymers based on polyvinylamine (PVAm).

  Capillary number is a dimensionless number used to characterize the possibility of breakage of this droplet. A large capillary number indicates greater fluid stability upon exiting the die. The number of capillaries is defined as follows:

Ｖは、ダイ出口での流体粘度であり（時間当たりの長さの単位）、
ηは、ダイの条件下での流体粘度（長さ当たりの質量の単位×時間）であり、
σは、流体の表面張力（時間^２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、結果として得られる毛管数はそれ自身の単位を持たず、個々の単位は相殺される。

V is the fluid viscosity at the die exit (unit of length per hour),
η is the fluid viscosity (unit of mass per length x time) under die conditions,
σ is the surface tension of the fluid (unit of mass per time ² ). When speed, viscosity, and surface tension are expressed in a series of consistent units, the resulting capillary number does not have its own unit and individual units are offset.

  The number of capillaries is defined for the condition at the die exit. The fluid velocity is the average velocity of the fluid passing through the die opening. Average speed is defined as:

Ｖｏｌ’＝体積流量（時間当たりの長さ^３の単位）
面積＝ダイ出口の断面積（長さ^２の単位）である。

Vol ′ = volume flow rate (unit of length ³ per hour)
Area = cross-sectional area of die exit (unit of length ² ).

  If the die opening is a circular hole, 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 depends on temperature and may depend on shear rate. The definition of shear thinning fluid includes dependence on shear rate. The surface tension depends on the fluid composition and the fluid temperature.

  In the fiber spinning process, the filament needs to have initial stability upon exiting the die. Capillary number is used to characterize this initial stability criterion. In the die state, the number of capillaries needs to exceed 1 and / or exceed 4.

  In one example, the filament forming composition exhibits a capillary number of at least 1 to about 50, and / or at least 3 to about 50, and / or at least 5 to about 30.

  Although the fibrous structure can be in solid form, the filament-forming composition used to make the filaments can be in liquid form.

  In one example, the fibrous structure may include a plurality of forms that are the same or substantially the same as the filaments in terms of composition. In other examples, the fibrous structure may include two or more different filaments. Non-limiting examples of differences within the filament include physical differences (eg, differences in diameter, length, texture, shape, stiffness, elasticity, etc.); chemical differences (eg, cross-linking level, solubility, melting point, Tg, activity) Agent, filament forming material, color, active agent concentration, filament forming material concentration, presence of any coating on the filament, whether biodegradable, hydrophobic, contact angle, etc.); The difference in whether the filament loses its physical structure when exposed to the conditions of use; the difference in the shape of the filament when the filament is exposed to the conditions of use intended; As well as the difference in whether the filament releases its one or more active agents when the filament is exposed to the intended conditions of use. In one example, two or more filaments within a fibrous structure include the same filament forming material, but may have different active agents. This may be the case when different active agents such as anionic surfactants (eg shampoo active agents) and cationic surfactants (eg hair conditioner actives) are not compatible with each other.

  In other examples, the fibrous structure may include two or more different layers (in the z direction of the fibrous structure of the filaments forming the fibrous structure). The in-layer filament may be the same as or different from the filaments in another layer. Each layer may include a plurality of filaments that are the same, substantially the same, or different. For example, filaments that can release their active agents in the fibrous structure at a faster rate than others may be disposed on the outer surface of the fibrous structure.

  In other examples, the fibrous structure may exhibit different regions, such as different regions of basis weight, density, and / or caliper. In yet other examples, the fibrous structure may include a texture on one or more of its surfaces. The surface of the fibrous structure may include a pattern (for example, a non-random repeating pattern). The fibrous structure may be embossed with an embossing pattern. In other examples, the fibrous structure may include an opening. The openings may be arranged in a non-random repeating pattern.

  In one example, the fibrous structure may include individual regions of filaments that are different from other portions of the fibrous structure.

  Non-limiting examples of the use of fibrous structures include laundry dryer substrates, laundry machine substrates, wash cloths, hard surface cleaning and / or polishing substrates, floor cleaning and / or polishing substrates, Ingredients in the battery include baby wipes, adult wipes, feminine hygiene wipes, toilet paper wipes, window cleaning substrates, oil containment and / or cleaning substrates, insect control substrates, chemical substrates for swimming pools, food , Bad breath prevention agent, deodorant, garbage disposal bag, packaging film and / or wrap, wound dressing, pharmaceutical delivery, building insulation, crop and / or plant cover and / or nursery, adhesive substrate, skin care substrate, Hair care substrate, air care agent, water treatment substrate and / or filter, toilet bowl cleaning substrate, candy substrate, pet food, livestock litter, tooth whitening substrate, carpet cleaning substrate, and Another preferred use of sex agent include, but are not limited to.

  The fibrous structure may be used as is or may be coated with one or more active agents.

  In other examples, the fibrous structure may be compressed into a film, for example, by applying compressive force and / or heat to the fibrous structure to convert the fibrous structure into a film. . The film will contain the active agent present in the filament. The fibrous structure may be completely converted to a film, or a portion of the fibrous structure may remain in the film after partial conversion of the fibrous structure to film. Films may be used for any suitable purpose in which an active agent may be used, including but not limited to the uses exemplified for fibrous structures.

B. Methods of Using Detergent Products Nonwoven webs or films that include one or more fabric care actives may be utilized in methods of treating fabric articles. A method of treating a fabric article includes: (a) pre-treating the fabric article before washing the fabric article; (b) a cleaning liquid formed by contacting the nonwoven web or film with water; and the fabric article. (C) contacting the fabric article with the nonwoven web or film in the dryer; (d) drying the fabric article in the presence of the nonwoven web or film in the dryer; e) One or more steps selected from the group consisting of these may be included.

  In some embodiments, the method may further comprise pre-wetting the nonwoven web or film prior to contacting the nonwoven web or film with the fabric article to be pretreated. For example, the nonwoven web or film may be attached to a portion of the fabric containing the stain that is pre-wetted with water and then pretreated. Alternatively, the fabric may be wetted and the web or film may be placed on or attached to it. In some embodiments, the method may further comprise selecting only a portion of the nonwoven web or film for use in processing the fabric article. For example, if only one fabric care article is being processed, a portion of the nonwoven web or film is cut and / or torn and placed on or attached to the fabric, or Placed in water to form a relatively small amount of cleaning liquid, which is then used to pretreat the fabric. In this method, the user can customize the fabric processing method by the work in front of him. In some embodiments, at least a portion of the nonwoven web or film may be applied to the fabric being processed using the apparatus. Representative devices include, but are not limited to, brushes and sponges. Any one or more of the foregoing steps may be repeated to obtain the desired fabric treatment effect.

VII. Manufacturing method of fibrous structure The following method was used in the formation of Examples 1-8 described in this specification. The fibrous structure is produced by using a small device, the schematic of which is shown in FIG. A pressurized tank suitable for batch operation was filled with a material suitable for spinning. The pump used was a Zenith® PEP II with a capacity of 5.0 cubic centimeters per revolution (cc / rev) from Parker Hannifin Corporation, Zenith Pumps division (Sanford, NC, USA). It was. The material flow to the die was controlled by adjusting the pump revolutions per minute (rpm). The tank, pump, and die were connected by a pipe.

  The die of FIG. 8 had several rows of circular extrusion nozzles spaced apart from each other by a pitch P (FIG. 8) of about 1.524 millimeters (about 0.060 inch). The nozzle had an individual inner diameter of about 0.305 millimeters (about 0.012 inches) and an individual outer diameter of 0.813 millimeters (about 0.032 inches). Each individual nozzle was surrounded by an annular, divergent flared orifice to supply reduced air to each individual melting capillary. The material being extruded through the nozzle was reduced in diameter by being surrounded by a stream of substantially cylindrical moist air fed through the orifice.

  The reduced air can be supplied by heating the compressed air from a source with an electrical resistance heater, for example, a heater from Chromalox, Division of Emerson Electric (Pittsburgh, Pa., USA). An appropriate amount of steam was added to saturate or nearly saturate the heated air at conditions in the electrically heated and thermostatically controlled delivery pipe. The condensate was removed in an electrically heated and thermostat controlled separator.

  The initial stage fiber is dried with a stream of dry air, which is heated by an electrical resistance heater (not shown) to a temperature of about 149 ° C. (about 300 ° F.) to about 315 ° C. (about 600 ° F.). And delivered through a drying nozzle and discharged at an angle of about 90 ° relative to the overall orientation of the early stage non-thermoplastic fibers being extruded. The dried early stage fibers were collected on a collection device (such as a movable perforated belt or molded member). A vacuum source added just below the forming zone may be used to assist in fiber collection.

  Table 1 below shows an example of a filament-forming composition for making a filament and / or fibrous structure suitable for use as a laundry detergent. This mixture was prepared and placed in the pressurized tank of FIG.

１ Ｃｅｌｖｏｌ ５２３、Ｃｅｌａｎｅｓｅ／Ｓｅｋｉｓｕｉ、分子量８５，０００〜１２４，０００、８７〜８９％加水分解

1 Celvol 523, Celanese / Sekisui, molecular weight 85,000-124,000, 87-89% hydrolysis

  The early dry filaments can be collected on the molded member as described above. The configuration of the molded member provides an area that is breathable due to its inherent configuration. The filaments used to construct the molded member are impermeable, but the void area between the filaments is permeable. In addition, a pattern may be applied to the molded member to provide additional impermeable areas that may be essentially continuous, discontinuous, or semi-continuous. The vacuum used at the time of deposition is used to assist in deflecting the fibers into the presentation pattern. An example of one of these molded members is shown in FIG.

  The underlying spinning conditions were achieved by collecting the fiber web on a collection molded member. These passed under the die and samples were collected after going through a vacuum. This process was repeated and samples were collected using 8 molded parts with different designs. A representative image of the molded member and the resulting fibrous structure is shown in FIG. 10 (for example, Invention Examples 1 to 8 described in the present specification). These fibrous structures may then be further processed.

  The process of forming the fibrous structure is further described in US Pat. No. 4,637,859.

  In addition to the techniques described herein for forming regions with different properties (eg, average density) in the fibrous structure, other techniques can be applied to obtain good results. One example is an embossing technique for forming such a region. Suitable embossing techniques are described in U.S. Patent Application Publication Nos. 2010/0297377, 2010/0295213, 2010/0295206, 2010/0028621, and 2006/0278355. .

Test Methods Unless otherwise indicated, all tests described herein, including those described in the Definitions section, and the following test methods must be performed at a temperature of 23 ° C. ± 1 for a minimum of 2 hours prior to testing. Performed on samples conditioned at 0C and relative humidity 50% ± 2%. All tests are performed under the same ambient conditions. Samples with defects such as wrinkles, tears, holes, etc. are not tested. Samples prepared as described herein are considered to be dry samples (eg, “dry filaments”) for purposes of purposes. In addition, all tests are performed in such a conditioned room.

Basis Weight Test Method The basis weight of the nonwoven structure and / or the dissolved fibrous structure is measured on a stack of twelve usable units using an upper dish chemical balance with a resolution of ± 0.001 g. The balance was protected from airflow and other disturbances by using a windshield. All samples are prepared using a precision punching die of 8.000 cm ± 0.0089 cm (3.500 in ± 0.003 in) × 8.89 cm ± 0.0089 cm (3.500 in ± 0.0035 in).

  Cut the sample into squares with a precision punching die. A laminated body of 12 sample thicknesses is formed by combining the cut squares. Measure the mass of the sample stack and record the result in units of 0.001 g.

Basis weight is calculated as lbs / 3000 ft ² or g / m ² as follows.
Basis weight = (mass of laminate) / [(area of one square in laminate) × (number of squares in laminate)]
For example,
Basis weight (lbs / 3000 ft ² ) = [[Mass of laminate (g) /453.6 (g / lbs)] / [12.25 (in ² ) / 144 (in ² / ft ² ) × 12]] × 3000
Or
Basis weight (g / m ² ) = Mass (g) of laminate / [79.032 (cm ² ) / 0000 (cm ² / m ² ) × 12]

Results are reported in 0.1 lbs / 3000 ft ² or 0.1 g / m ² units. As the sample area in the stack is at least 645.2cm 2 ⁽¹⁰⁰ square inches), it is possible to change or vary the size of the sample using the same precision cutter to those described above.

Water content test method The water content (moisture content) present in filaments and / or fibers and / or nonwoven webs is measured using the following water content test method.

Filaments and / or nonwovens, or portions thereof (“samples”), are placed in a room adjusted to a temperature of about 23 ° C. ± 2.2 ° C. and a relative humidity of 50% ± 10% for at least 24 hours prior to testing. The area of each sample is at least 25.8 cm ² (4 square inches), but small enough to fit properly on the weighing pan of the balance. Under the temperature and humidity conditions described above, use a balance with at least 4 decimal places and weigh the sample every 5 minutes until a change of less than 0.5% of the previous weight is detected in 10 minutes Record. Record the final weight as "balance weight". Within 10 minutes, the sample is placed in a forced air oven and placed on the foil and allowed to dry for 24 hours at a temperature of 70 ° C. ± 2 ° C. and a relative humidity of 4% ± 2%. After drying for 24 hours, the sample is removed and weighed within 15 seconds. This weight is expressed as the “dry weight” of the sample.

  The water content (moisture content) of the sample is calculated as follows:

  To report the moisture content (moisture content)% in the sample, the moisture content (humidity content)% in the sample for the three replicates is averaged. Report results to the nearest 0.1%.

Dissolution test method Equipment and materials (see also FIGS. 11 and 12):
600mL beaker 240
Magnetic stirrer 250 (Labline Model No. 1250 or equivalent)
Magnetic stir bar 260 (5cm)
Thermometer (1-100 ° C +/- 1 ° C)
Punching die--stainless steel punching die (dimensions 3.8cm x 3.2cm)
Timer (0-3600 seconds or 1 hour), accurate to seconds. When the sample exhibits a dissolution time of greater than 3,600 seconds, the timer used must have a sufficient total time measurement range. However, the timer needs to be accurate to the second.
Polaroid 35mm slide (available or equivalent from Polaroid Corporation)
35mm slide base holder 280 (or equivalent)
Cincinnati city tap water or equivalent with the following characteristics: CaCO ₃ as a total hardness = 155 mg / L; calcium content = 33.2 mg / L; magnesium content = 17.5 mg / L; phosphate content = 0.0462.

Test Protocol Equilibrate the sample for at least 2 hours in a constant temperature and humidity environment of 23 ° C. ± 1 ° C. and 50% RH ± 2%.

  The basis weight of the sample material is measured using the basis weight method defined herein.

  Three elution test samples are cut (3.8 cm × 3.2 cm) from the nonwoven structure using a punching die so that it fits within a 35 mm slide 270 with an open area dimension of 24 × 36 mm.

  Each sample is fixed to a separate 35 mm slide base 270.

  A magnetic stirring bar 260 is placed in a 600 mL beaker 240.

  Twist the tap water stream (or equivalent), measure the water temperature with a thermometer, and adjust the hot or cold water if necessary to maintain the water at the test temperature. The test temperature is 15 ° C. ± 1 ° C. water. When the test temperature is reached, the beaker 240 is filled with tap water at 15 ° C. ± 1 ° C.

  Place the filled beaker 240 on top of the magnetic stirrer 250 and switch on the stirrer 250 to adjust the stirring speed until a vortex is generated and the bottom of the vortex is at the 400 mL mark on the beaker 240. .

  The 35 mm slide base 270 is fixed in the alligator clamp 281 of the 35 mm slide base holder 280 so that the long end 271 of the slide base 270 is parallel to the surface of the water. The alligator clamp 281 must be positioned in the middle of the long end 271 of the slide base 270. The depth adjustment device 285 of the holder 280 is such that the distance between the bottom surface of the depth adjustment device 285 and the bottom surface of the alligator clip 281 is 11 +/− 0.125 inches (27.9 +/− 0.318 cm). Must be set to With this setting, the surface of the sample is arranged to be perpendicular to the water flow. A slightly modified embodiment of the 35 mm slide base and slide base holder arrangement is shown in FIGS. 1-3 of US Pat. No. 6,787,512.

  In one movement, the fixed slide base is submerged and the timer is started. Submerge the sample so that it is in the center of the beaker. Collapse occurs when the nonwoven fabric structure is broken. Record this as the decay time. When all of the visible nonwoven structure has been released from the slide table, the slide table is lifted from the water while observing the water for fragments of the nonwoven structure that have not dissolved. Dissolution occurs when all the nonwoven structure fragments are no longer visible. This is recorded as the dissolution time.

  Perform on 3 replicates of each sample and record the average disintegration and dissolution time. Average disintegration and dissolution times are in seconds.

The average disintegration and dissolution times are normalized with respect to the basis weight by dividing each of the average disintegration and dissolution times by the basis weight of the sample determined by the basis weight method as defined herein. Disintegration and dissolution times normalized by basis weight are in units of gsm of second / sample (s / (g / m ² )).

Average Density Test Method The fibrous structure may include a network region having an intrinsic density and a plurality of individual zones. An SEM micrograph of a cross section of such a fibrous structure is shown in FIG. The areas of the fibrous structure are shown in the micrograph based on zones containing different calipers or thicknesses. These caliper differences are one of the factors involved in the excellent performance characteristics of these fibrous structures.

  Regions with high calipers have a low density of structures, which are typically referred to as “pillows”. Regions with low calipers are dense in structures and are typically referred to as “knuckles”.

  The density of the area within the fibrous structure is initially at least 2 to 3 with a previously unused single-edged PTFE-treated razor blade (eg, GEM® razor blade available from Ted Pella Inc.). Measured by cutting over the length of the knuckle and pillow region. Cutting is only once per razor blade. Each sample horizontal piece is attached to the SEM sample holder, fixed with carbon paste, and then frozen in liquid nitrogen. Samples were transferred to a SEM chamber at −90 ° C., coated with gold / palladium for 60 seconds, commercially available SEM with cryo system (eg, Hitachi S-4700 with Alto cryo system) and PCI (Passive Capture Imaging) software Or using an equivalent SEM system and equivalent software. All samples are evaluated while frozen to ensure their original dimensions and shape under vacuum while they are in the scanning electron microscope.

  The thickness of the pillows and knuckles, or the thickness of the reticulated areas and individual zones, is determined using analysis software associated with the SEM instrument. Since the measurement is the thickness of the sample, such analysis software is the standard for all SEM instruments. Measurements are performed where the thickness of the region or zone is at its local maximum. Record the thickness value of at least two individual discrete mesh areas (or individual zones), then average and record as the mesh area average thickness. Average thickness is measured in units of micrometers.

Separately, the basis weight of the sample to be measured for density is determined using the basis weight method defined herein. The basis weight measured by gsm (g / m ² ) is measured by the basis weight method and used for calculation of the area density.

Shown below is an example of calculating the net area average density and individual zone average density of a sample having a basis weight of 100 g / m ² , a net area average thickness of 625 micrometers, and an individual zone average thickness of 311 micrometers. It is.

Diameter Test Method The diameter of individual filaments in a nonwoven web or film is determined by using a scanning electron microscope (SEM) or optical microscope and image analysis software. A magnification of 200 to 10,000 times is selected so that the filament is properly expanded for measurement. When using SEM, the sample is sputtered with gold or palladium compounds to avoid charging and vibration of the filament in the electron beam. From the images (on the monitor screen) taken using an SEM or light microscope, the filament diameter is determined using a manual procedure. Use the mouse and cursor tools to find the edge of the randomly selected filament and then across its width to the opposite edge of the filament (ie, perpendicular to the filament direction at that point) )taking measurement. A calibrated, calibrated image analysis tool provides a scale for obtaining actual readings in μm, for example. For filaments in a nonwoven web or film, several filaments are randomly selected from across the nonwoven web sample using SEM or optical microscopy. At least two portions of the nonwoven web or film (or web in the product) are cut out and tested in this way. For statistical analysis, all data are recorded after at least 100 such measurements have been made. The recorded data is used to calculate the average filament diameter (average), the standard deviation of the filament diameter, and the median diameter of the filament diameter.

  Another useful statistic is the calculation of the amount of population of filaments that is below a certain upper limit. To determine this statistic, the software is programmed to count how many of the filament diameters are below the upper limit, and this count (divided by the total number of data and multiply by 100%) ) Is recorded in percent as a percent that is less than the upper limit (eg, a percent that is 1 micrometer or less in diameter, or a percent that is submicron). We denote the measured diameter (in μm) of individual circular filaments as di.

  If the filament has a non-circular cross-section, the measurement of the filament diameter is determined as and equal to the hydraulic diameter, which is 4 times the filament cross-sectional area ( In the case of a hollow filament, it is divided by the outer periphery). Number-average diameter, or average diameter, is calculated as follows:

Tensile Test Method: Elongation, Tensile Strength, TEA, and Elastic Modulus Elongation, Tensile Strength, TEA, and Tangential Modulus are measured using a load cell whose measured force is within 10% to 90% of the cell limit. Measured with a constant speed tensile tensile tester with an interface (a suitable instrument is the EVA Vantage available from Thwing-Albert Instrument Co. (Wet Berlin, NJ)). Both movable (upper) pneumatic grips and fixed (lower) pneumatic grips are fitted with opposing stainless steel grips that are 25.4 mm high and wider than the width of the test sample. Air pressure of about 0.41 MPa (60 psi) is supplied to the gripper.

  The eight usable units of the nonwoven structure and / or the dissolved fibrous structure are divided into two laminates with a set of four samples. Samples in each laminate are sequentially oriented with respect to the machine direction (MD) and the width direction (CD). One of the laminates is designated for MD testing and the other is designated for CD testing. Using a 1 inch precision cutter (Thwing Albert JDC-1-10, or similar), cut 4 MD strips from one laminate and 4 CD strips from the other, The strip dimensions are 2.54 cm ± 0.0254 cm (1.00 in ± 0.01 in) wide and 7.6-10.0 cm (3.0-4.0 in) long. Each strip of one usable unit thickness is treated as a single specimen for testing.

  Force and stretch at an acquisition rate of 20 Hz as the tensile tester is programmed to perform a stretch test and the crosshead is raised at a rate of 5.08 cm / min (2.00 in / min) until the specimen breaks. Collect data. The break sensitivity is set to 80%, i.e. the test is terminated when the measured force drops to 20% of the maximum peak force, after which the crosshead is returned to its original position.

  The gauge distance is set to 2.54 cm (1.00 inch). Set crosshead and load cell to zero. A single specimen of at least 2.54 cm (1.0 in) is inserted into the upper grip, vertically aligned within the upper and lower grips, and the upper grip is closed. A single specimen is inserted into the lower grip and closed. A single specimen must be placed under sufficient tension to remove all sagging, but the load cell force should be less than 0.05 g. Start the tensile tester and collect data. The test is repeated for all four CD single specimens and all four single specimens.

  The software is programmed to calculate the following from the generated force (g) vs. extension (in) curve:

  Tensile strength is the maximum peak force (g) divided by the width of the sample and is reported in g / in in units of 0.0039 N / cm (1 g / in).

  The adjusted gauge distance is calculated as the extension (in) measured when 0.03N (3.0 g force) is added to the original gauge distance (in).

  Elongation is calculated as the maximum peak force (in) divided by the adjusted gauge distance (in) multiplied by 100 and reported as a percentage in units of 0.1%.

Total energy (TEA) is the area under the force curve (g ^* in) integrated from zero extension to extension at maximum peak force, adjusted gauge distance (in) and specimen width (in) And divided by 0.39 J / m ² (1 g ^* in / in ²⁾ units.

  Re-plot the force (g) vs. extension (in) curve to the force (g) vs. strain curve. Distortion is defined herein as the extension (in) divided by the adjusted gauge distance (in).

  The software is programmed to calculate the following from the force (g) versus strain curve.

  The tangential modulus is calculated as the slope of a linear line drawn between two data points on the force (g) versus strain curve, where one of the data points used is recorded after 0.27 N (28 g force). The other data point used is the first data point recorded after 0.47 N (48 g force). This slope is then divided by the specimen width (2.54 cm) and reported in units of 0.0098 N / cm (1 g / cm).

Tensile strength (g / in), elongation (%), total energy (g ^* in / in ² ), and tangential modulus (g / cm), 4 CD single specimens and 4 MD single specimens Calculate about. The average of each parameter is calculated separately for each CD and MD specimen.

Calculation:
Geometric average tensile strength = square root of [MD tensile strength (g / in) × CD tensile strength (g / in)] Geometric average peak elongation = square root of [MD elongation (%) × CD elongation (%)] Geometric average TEA = Square root of [MD TEA (g ^* in / in ² ) × CD TEA (g ^* in / in ² )] Geometric mean elastic modulus = [MD elastic modulus (g / cm) × CD elastic modulus (g / cm)] Square root Total dry tensile strength (TDT) = MD tensile strength (g / in) + CD tensile strength (g / in)
Total TEA = MD TEA (g ^* in / in ² ) + CD TEA (g ^* in / in ² )
Total elastic modulus = MD elastic modulus (g / cm) + CD elastic modulus (g / cm)
Tension ratio = MD tensile strength (g / in) / CD tensile strength (g / in)

Topographic measurements of fibrous structures with density differences Topographic measurements of fibrous structures with density differences are obtained by a computer-controlled fringe projection optical shape measurement method. The optical profilometry system measures the physical dimensions of the test surface and generates a map of surface elevation in elevation (z) versus lateral displacement in the XY plane. A suitable optical profilometer has a field of view and resolution so that the acquired image has at least 10 pixels linearly across the narrowest feature to be measured. A suitable instrument is a GFM Microcad system running version 4 or 6 of the ODSCAD software, or equivalent, available from GFMesstechnik GmbH (Teltow, Germany).

  Lightly spray a fine white powder spray onto the surface to be measured, if necessary to ensure that the sample has adequate reflectivity to accurately measure surface features. Preferably, the spray is NORD-TEST Developer U 89 available from Helling GmbH (Heidgraben, Germany) sold to detect cracks in metal bodies and welds. The sample must be equilibrated at 23 ° C. ± 2 ° C. and 50% ± 2% relative humidity for at least 2 hours just prior to applying such spray and for at least 2 hours after spraying. Care is taken to deposit only the minimal amount of white spray necessary to form a light white reflective coating.

  Samples must be equilibrated for at least 2 hours at 23 ° C. ± 2 ° C. and 50% ± 2% relative humidity immediately before taking measurements.

  The area to be measured of the fibrous structure is limited to only areas having regions of different densities, and other areas or zones that may be present are excluded. The sample is placed so that the surface area to be measured faces upwards and is below and perpendicular to the profilometer projection head. According to the instrument manufacturer's instructions, optimal illumination and reflection requirements are achieved as outlined by the manufacturer. Next, the digital image is captured and stored.

  Any part of the image that is not part of the area to be measured must be cropped from the captured image. Such trimming must be done prior to further image processing, image filtering, or measurement analysis. The size of the resulting cropped image can vary between the sample and the image depending on the size of the patterned area of the sample.

  Before performing the measurement, the image of the instrument software is processed in order to smooth the noise contained in the image a little and reduce the unevenness and waveform caused by the overall shape of the sample. This noise removal process removes invalid pixel values (black pixels having a gray value at the black limit value of the gradation range), and spike values or abnormal value peaks (the saltware is identified as statistically abnormal values). Bright pixel) removal. A polynomial high-pass filter is used with the following settings: n = 8, difference. For samples with very small features where it is difficult to clearly observe pattern features, it may be useful to apply a Fourier filter (eg: millimeter wave filter, resulting in fine structure). When using such a Fourier filter, features larger than the filter length are removed as noise, thus reducing variability and reducing the statistical standard deviation for topographic measurements. Therefore, it is essential that the size of the filter used is larger than the size of the feature so as not to remove any feature of interest. For example, a processed image such as the topographic image shown in FIG. 14 can be displayed, analyzed, and measured. FIG. 14 is filtered with a polynomial filter (n = 8 differences) after trimming to remove irregularities due to the overall waveform of the sample.

  Next, measurement is performed from the processed topography image to obtain a spatial parameter of altitude difference (E) and a transition region width (T). Such a measurement is accomplished using instrument software that draws a region of interest straight line in the topographic image of the xy plane of the sample and then generates a height profile plot along these lines. The target straight line region is drawn to sample various different locations within each image across the continuous region and the center of adjacent individual zones. A line is drawn to bisect each transition region between continuous and individual zones at an angle perpendicular to the long axis of the transition region, as shown in FIG. As shown in FIG. 15, a series of lines of interest are drawn across continuous and individual zones and bisect each transition region at an angle perpendicular to the long axis of the transition region. Next, parameters (E) and (T) are measured from the height profile plot generated from these target straight line regions.

  In a height profile plot, the x-axis of the plot represents the length of the line and the y-axis represents the vertical height of the plane perpendicular to the planar surface of the sample. The height difference (E) is measured in micrometers on the height profile plot shown in FIG. 16 as the vertical linear distance from the peak apex to the adjacent recess. As shown in FIG. 16, the height profile plot along the target straight line region drawn on the topography image shows several elevation difference (E) measurements. Typically this represents the maximum vertical height difference between the surface of the continuous area and the adjacent individual zone, or vice versa. The transition region width (T) is measured in micrometers on the height profile plot shown in FIG. 17 as the x-axis width of the curve crossing the center 60% of the height difference (E). As shown in FIG. 17, the height profile plot along the target straight line region drawn on the topography image shows several transition region widths (T). Typically this represents the rate of transition from a continuous region to an adjacent individual zone or vice versa.

  If the sample has individual zones that appear to be classified into two or more distinct classes when the shape, dimensions, height, and density of the individual zones as a whole are visually determined, Separate values (E) and (T) are determined for each combination of class and adjacent continuous regions.

  If the sample visually shows that it has two or more individual zones of pattern at different locations on the product, each pattern has an (E) and (T) value that is determined separately from the other patterns. Have.

  If the sample has a first region and an adjacent second region and the surface ridges of the first region and the second region are visually different, the product is measured from these regions. (E) and (T) values. In this case, according to any method instructions presented herein, the first region and the second region are replaced with continuous region zones and individual zones named in this manner.

  For each pattern to be tested, five replicate product samples are imaged, and from each replicate sample, at least 10 altitude differences (E) for each class of individual zones and at least 10 transition regions for each class of individual zones. The width (T) is measured. This is repeated for each planar surface of each sample. The values of (E) and (T) are reported from the planar surface with the maximum value of (E). For each parameter calculated for a particular pattern and individual zone class, the values from each of the five replicate samples are averaged together to obtain the final value for each parameter.
