REFERENCE TO RELATED APPLICATION
 This application claims the benefit of Provisional Patent Application No. 61/255,084, filed on Oct. 26, 2009, entitled "Cologne/Perfume Scented Dryer Sheets", in the United States Patent & Trademark Office, the disclosure of which is incorporated herein by reference.
BACKGROUND OF THE INVENTION
 Dryer sheets containing a softener and, occasionally, including a fragrance, have been commercially available since the late 1970s. A dryer sheet is placed with clothing in a heated tumble dryer and the softener is transferred from the dryer sheet to the clothing to remove wrinkles and improve the "hand" of the clothing. However, usually any fragrance that is provided in the dryer sheet is merely a single component with a recognizable flowery or powdery scent. Dryer sheets having a fragrance corresponding to or resembling popular name brand complex perfumes or colognes are not commercially available, nor are dryer sheets having customized fragrances.
 Most scented dryer sheets, however, are floral or powder scented with a single component and have similar scents, and they are not available in popular perfume or cologne scents, such as Chanel No. 5. Also, the names of the scents on the dryer packaging do not describe the fragrance in a manner that can be compared with other existing fragrances, such as by olfactory category (e.g., flowery, woody, etc.)
 Fragrances, such as colognes and perfumes, have been used for centuries. The use of fragrances directly applied to clothing, such as by splashing or spraying, is also well known, e.g., Peau d'Espagne and Buddha's Hand are well known for such use in southern Europe and the Far East. Also, sachets containing fragrant herbs and flowers have often been placed in wardrobes to transfer fragrance to clothing.
 Complex fragrances are made up of several volatile scent components (i.e., chemicals) in an ethanol-water solvent that evaporate over time, giving off one or more aromas (or scents). In the early history of perfumes, scent components were obtained from natural sources, such as those that could be extracted or distilled from flowers, tree barks and other plant materials into essential oils or concretes. Examples of "essential oils" obtained from these natural sources include: bergamot, jasmine, violet, lavender, orange, cedar, patchouli, and sandalwood. Another natural source for scents is animals, such as musk (from the musk deer), civet (from the civet cat) and ambergris (from whales' regurgitation).
 However, nowadays, many perfume scents are made artificially, e.g., from petroleum or vegetable sources, some of which closely resemble certain natural scents. New synthetic scents are also continually being produced. One of the first perfumes to include synthetic components was Chanel No. 5, which uses a particular set of synthetic aldehyde scent components. Scent components made chemically from vegetable sources, specifically vegetable oils, are often called "green", because they are renewable, as contrasted with petroleum oil and other "fossil mineral" sources, such as coal or gas.
 Today's perfumes are typically made of a mixture of several volatile scent components, i.e., they are "complex" as compared to "simple" fragrances having only one or two scent components. Each scent component is usually a specific volatile chemical compound. The scent components can broadly be categorized in any of various groups based on type of recognizable olfactory scent, such as the broad categories of: flowery, fruity, animal, woody, spicy, powdery, sugary and Chypre (i.e., originating from Cyprus). Newer scent categories have also been added as new scent components are discovered, reacted or manufactured.
 The most volatile group of components in the complex fragrance mixture of a perfume or cologne, i.e., those which are sensed when the perfume is initially applied to clothing or skin or when the bottle is opened, are collectively called the "top note", and last only for a very short period of time, i.e., seconds to several minutes, before completely evaporating. This "top note" generally comprises about 20-30% of the overall scent composition of the perfume or cologne. They are intended to evoke an interest in the remaining (heavier) scent components.
 The next group of scent components in terms of volatility, which are collectively called the "middle note", are considered to be the "heart" or "main theme" of the fragrance and they volatilize more slowly than the top notes, e.g., taking several minutes up to a few hours to evaporate. This "middle note" comprises about 25-40% of the overall scent. Finally, the last group of components in terms of volatility, collectively called the "end note" (or sometimes "base note"), make up the remaining 25-40%, have the lowest volatility and can last several hours.
 These aspects of fragrances are described in "The Chemistry of Fragrances", by D. Pybus and C. Sell, (Royal Society of Chemistry, 1999).
Brand Name Fragrances
 One of the earliest name brand fragrance is called 4711 Original Eau de Cologne that was launched by Maurer & Wirtz in 1792, with a now-recognizable blue and gold bottle, which is based on an earlier fragrance that was simply called "Eau de Cologne" that was previously made by the famous Italian perfumer Johann Maria Farina. According to the website, 4711.com, the top note (collectively called "head note" here) includes bergamot, lemon, and orange essential oils; the middle note (collectively called "heart note" here) includes lavender and rosemary; and, the end note (called "base" here) includes neroli. Thus, at least six scent components are provided in this cologne. Additional ingredients are listed for 4711 on the website fragrantica.com.
 Another well known fragrance is Chanel No. 5 which includes notes (according to website, chaneln5.com): aldehydes, rose, jasmin, ylang-ylang and sandalwood. In this fragrance, at least 5 scent components are included. Additional scent components in this fragrance are given at the website: frangrantica.com.
 Perfumes, colognes, and other types of "designer" fragrances are made up of many scent components, in addition to the water and ethanol solvent in which the scent components are dissolved. By contrast, the fragrances added to dryer softener sheets usually only include one or two scent components, and these generally only have a floral scent. Dryer sheets having designer fragrances or comparable fragrances that resemble well known perfumes and colognes, are not commercially available.
 There has been an ongoing need for popular complex fragrances to be provided on clothing, without having to carry a perfume or fragrance bottle to apply the fragrance directly onto the clothing or to reapply throughout the day. Also, spraying the fragrance onto the clothing results in "hot spots" of strong fragrance scent on the hot spots, with other areas of the clothing being fragrance-free. There is a need to apply the complex fragrance evenly onto the clothing to create a consistent, complex scent emitting from the person who wears the scented clothing. Also, there is a need for customized fragrances that have a selectable desired longevity on clothing, such as a short duration of 30-60 minutes or a longer duration of 6 hours, for example.
 This invention solves this problem by providing a complex fragrance on a dryer sheet that is added to the clothes prior to a fluff drying cycle, i.e., a tumble drying cycle without added heat. More particularly, this invention ensures that the fragrance is matched with an optional compatible surfactant ingredient included in the dryer sheet, in order to obtain the longest lasting fragrance effect on the clothing. An additional optional fixative may also be added to reduce the volatility of the "top note" so that its longevity in the clothes can be extended, if desired. The complex fragrance, optional surfactant, fixative and other components are preferably marked, along with other indicia, on the dryer sheet packaging to match the fragrance and additives to the most compatible clothing textile and to indicate the approximate longevity of the fragrance on the clothing.
 In certain situations, the user may prefer to shorten the longevity of the complex fragrance, such as when using on clothing used by babies or small children to cover certain odors like diaper odors. The diaper or other baby clothing can then be tumbled with a scented dryer sheet to impart the desired scent onto the diaper or clothing. The indicia may indicate a 1 or 2 hour longevity for this use.
 Also, as the natural scent components become progressively substituted with newly chemically produced "green" vegetable-based oils, this can be indicated on the packaging as well. Thus, this invention anticipates the need for informing consumers about "green" ingredients in scented products and its possible legislation.
 Furthermore, the indicia can list the particular brand name fragrances and their percentage fractions, or, alternatively, a list of all of the scent components (including both the chemical name and the scent category corresponding to the chemical).

 However, none of these documents disclose or teach providing a set of at least two different scented dryer sheets, selecting a scented dryer sheet having a complex popular perfume or cologne fragrance that can be evenly transferred to clothing in a non-heat tumble dryer cycle.
 Therefore, there is a need for a dryer sheet that can transfer a popular perfume or cologne fragrance evenly to clothing using a non-heat tumble dryer cycle.
BRIEF SUMMARY OF THE INVENTION AND OBJECTIVES
 The primary objective of the invention is to provide a customized perfume scented dryer sheet and a method of using the dryer sheet that will transfer a complex 3-note fragrance evenly to clothing during a non-heat tumble dryer cycle in which the dryer sheet is contained in a packaging with indicia identifying the type of fragrance(s) and their relative amounts.
 A second objective is to provide a customized perfume scented dryer sheet containing a complex fragrance in a major amount and optional additives in a minor amount, that has a given longevity the complex fragrance that is indicated on the packaging, such as "short" (30-60 minutes) or "extended" (6-8 hours).
 It is a further object to provide a customized perfume scented dryer sheet including a custom blend of two or more name brand perfumes and/or colognes that are selected by a user, which can be transferred evenly to clothing in a non-heat dryer cycle.
 It is yet a further object to provide customized perfume scented dryer sheets having a custom mixture of two or more brand name perfumes and/or colognes that are prepared to ensure a given longevity that is marked on the packagings.

 The substrates for the inventive dryer sheets are any nonwoven or woven fabric capable of containing the desired fragrance in an amount sufficient to apply to a given quantity of clothing, so that the fragrance is evenly applied to the clothing. The substrate can be prepared from cellulosic or modified cellulosic or rayon fibers, or any suitable fiber. Additional examples of fiber materials include synthetic fibers such as polyester, polyacrylic, polyalkylenene, and polyvinyl chloride, and natural fibers such as linen and wool. The size of the substrate, i.e., the surface area and volume, is sufficient to hold an amount of fragrance that is capable of transferring evenly to an amount of clothing that corresponds to a usual tumble dryer load, generally 5-10 pounds (about 2-5 Kg).
 Preferably, the fragrance, dryer sheet substrate and any additional extending components are compatible with the clothing to which the fragrance is transferred. This can be determined by evaluating the Partition Coefficient values of the fragrance components relative to the dryer sheet fabric fibers, and ensuring that the values for the fragrance-to-clothing are greater than the corresponding values for the fragrance-to-substrate.
 FIG. 1 shows a process for using a customized perfume scented dryer sheet 10 according to the invention. The customized perfume scented dryer sheet 10 (embedded with fragrance plus agent) is added to clothing 20 and placed in a tumble dryer machine 30 set for a non-heat cycle (i.e., a "fluff" cycle as used in the USA). The tumble dryer 30 must have a non-heat setting and allow for air to circulate and flow through the dryer to remove excess moisture. When the dryer sheet 10 tumbles with the clothes in this non-heat setting, the fragrance is transferred evenly to the clothing. At the end of the non-heat cycle, the clothes 20 are removed from the dryer 30 and will have an evenly distributed multi-note fragrance that resembles the desired fragrance.
 FIG. 2A shows a process for using a customized perfume scented dryer sheet 12 according to the invention. The customized perfume scented dryer sheet 12 (embedded with surfactant plus agent) is added to clothing 22 and placed in a tumble dryer machine 32 set for a heat cycle (i.e., a 10 minute cycle as used in the USA). The tumble dryer 32 must have a heat setting and allow for air to circulate and flow through the dryer 32 to remove excess moisture. When the dryer sheet 12 tumbles with the clothes 22 in this heat setting, the fragrance is transferred evenly to the clothing. At the end of the heat cycle, the clothes 22 are removed from the dryer 32 and will have an evenly distributed multi-note fragrance that resembles the desired fragrance.
 FIG. 2B shows a process for using a customized perfume scented dryer sheet 14 according to the invention. The customized perfume scented dryer sheet 14 (embedded with fragrance plus agent) is added to clothing 24 and placed in a tumble dryer machine 34 set for a heat cycle (i.e., a 10 minute cycle as used in the USA). The tumble dryer 34 must have a heat setting and allow for air to circulate and flow through the dryer 34 to remove excess moisture. When the dryer sheet 14 tumbles with the clothes 24 in this heat setting, the fragrance is transferred evenly to the clothing. At the end of the heat cycle, the clothes 24 are removed from the dryer 34 and will have an evenly distributed multi-note fragrance that resembles the desired fragrance.
Dryer Sheets--Fragrance and Optional Additive
 The packaging used for the dryer sheet will indicate the type of customized fragrance contained in the dryer sheet. This fragrance can be a popular "designer" fragrance, such as 4711 Eau de Cologne, Chanel No. 5 or Calvin Klein OBSESSION, for example.
 Preferably, a set of at least two different dryer sheets with different customized fragrances, in their respective packaging can be provided, so that a user can select among the differently customized perfume scented dryer sheets. The customized fragrance can be a designer perfume or cologne, or can contain comparable ingredients to resemble a popular perfume or cologne. In addition, the user can select two or more brand name perfumes or colognes to combine in the same dryer sheet. A plurality of these scented dryer sheets can be provided in a package or container marked with indicia identifying the names of the contained perfumes and/or colognes and their relative amounts.
 A designer perfume contains three "note" groups, called top, middle and end notes, each group corresponding to scent components that differ in volatility. The top note has the highest volatility and usually dissipates quickly, i.e., in seconds or minutes of release or application. However, during the air flow in the non-heat tumble dryer cycle, an agent can be added to reduce the volatility of the top note scent components.
 One agent that can be used is increased end note concentration. The end note will temporarily "carry" or "contain" the top note components by acting as a dense solvent, thereby slowing the release of the top note. The middle note components can similarly be "carried" by any additional end note components to slow their dissipation as well.
 Clothing can be made of any of various kinds of textile fiber, including natural and synthetic, or even metallic and mixed fibers. Natural fibers include cotton, wool, linen and silk. More commonly, synthetic fibers are used including polyester, nylon, SPANDEX, polyvinyl chloride, polyethylene, polypropylene, polyacrylic, and mixtures of these. In all cases, the fabric should be substantially dry before adding the scented dryer sheet with the clothes in the non-heat dryer cycle; this avoids having to remove excess moisture from the clothing during the fluff cycle as the fragrance is transferred from the dryer sheet substrate to the clothing.
Dryer Sheet Packaging
 As shown in FIG. 3A, the customized perfume scented dryer sheets 110 can be provided either individually packaged and sealed or as a continuous roll inside a sealable container 300. FIG. 3B shows an inner view of an exemplary roll of a plurality of dryer sheets 110 removable through a sealable opening 310 (e.g., a moisture lock lid) in a container 300.
 FIG. 3C shows a top view of the perforated customized perfume scented dryer sheets with visual indicating printout to indicate "ALMOST DEPLETE", "NEAR END" and "END". The dryer sheet 110 is perforated and sized 7'×8' inch.
 FIG. 3D shows a top view of an exemplary roll of a plurality of dryer sheets 110 removable through a sealable opening 310 (e.g., a moisture lock lid) in a container 300. Each container 300 can have 25 sheets, 50 sheets, 100 sheets and 200 sheets (jumbo size).
 FIGS. 4A and 4B shows a kit of two scented dryer sheets having different fragrances. The packaging of each dryer sheet is marked with the name or names of the scent in the dryer sheet. Optionally, each packaging can include an expiration date for the contained fragrances or the particular clothing fabric to which the fragrance is more favorably compatible (e.g., according to Partition Coefficient calculations).
 FIGS. 4A and 4B show exemplary package indicia for dispensers containing the scented dryer sheets. In FIG. 4A, the dryer sheets contain a "WOODY-FLORAL" scent made up of 90% Brand A and 10% Brand B. They have an estimated 1 hour of longevity, are made with 100% "green" material sources, and should be used on 90-100% polyester clothing. They are not to be used with clothing made of polyethylene.
 In FIG. 4B, the dryer sheets contain a "WOODY-SPICY" scent made up of 80% Brand C and 20% Brand D. They have an estimated 6 hours of longevity, are made with 50% "green" material sources, and should be used on 90-100% cotton clothing. The clothing should have less than 10% polyester, if the clothing is a fiber blend.
 In FIG. 5A, a process is shown for making two different dispensers, 250 and 252, each containing dryer sheets with different scent mixtures: 250 containing customized fragrance "DS a" and 252 containing customized fragrance "DS b".
 Initially, two or more fragrances are selected (in this case, Brands A and B and C and D, 52 and 54) and blended and added to the respective dryer sheets, 210 and 212, in amounts sufficient to be able to transfer the fragrance to a "normal" tumble dryer load (e.g., 5-10 lbs or 2.5-5 kg). The dryer sheets (210 and 212) are packaged in dispensers 250 and 252. In FIG. 5A, the dryer sheets are dispensed from the sealable opening 260. The shape of the dispenser and the geometric arrangement of the multi-dryer-sheet contents are generally unimportant and should only be aesthetically pleasing and useful. However, the container should be capable of sealing the opening, e.g., using a lid or other closure, to ensure that the fragrance components do not escape from the dryer sheets during storage. In the dispenser shown (250), the dryer sheets are dispensed individually through the opening 260 which can be provided with a sealing slit or a sealable closure (not shown).
 In FIG. 5B, each of the desired fragrances Brands A-D (56 and 58) are separately loaded onto individual dryer sheets, 214, 216, 218 and 220. Dryer sheets, 214 and 216, containing Brand A and Brand B are packaged in multi-compartment dispenser 254 marked as "DS ab". The dispenser 254 has a barrier to separate into at least two-compartments. 90% of the dryer sheets in the dispenser 254 are loaded with Brand A fragrance and 10% are loaded with Brand B fragrance. Similarly, dryer sheets, 218 and 220, containing Brand C and Brand D (56 and 58) are separately loaded onto individual dryer sheets and placed in dispenser 256. In the multi-compartment dispenser 256 shown in FIG. 5B, a central compartment containing sheets (218 and 220) with Brand C are dispensed from opening 262 through sealable slit 264. However, a sealable closure can also be used in place of or in addition to the slit, as long as the closure prevents the volatile fragrance components from escaping during storage.
 Dispenser 256 includes a second outer compartment that is separated from the central compartment (see 270) containing Brand D dryer sheets. These are dispensed through slit 282 in opening 280. This opening can also include or be replaced with a suitable sealing closure that prevents escape of the volatile scent components from the customized perfume scented dryer sheets.
 FIG. 5C shows single scented dryer sheet dispenser 280, with informational indicia 290. In this case, the dispenser contains "Custom Scented Dryer Sheets `ab`", containing a mixture of 90% Brand A and 10% Brand B fragrances. The olfactory category is "floral-woody", the longevity is short, or 30-60 minutes, the compatible clothing fabric is greater than 90% polyester, the expiration date is September 2014 and the ingredients are 100% "green".
 FIG. 5D shows dual scented dryer sheet dispenser 282, with informational indicia 292. In this case, the dispenser contains dual "Custom Scented Dryer Sheets `ab`". The customized perfume scented dryer sheets dispensed from the center compartment are loaded with Brand A fragrance which has a "floral" category, has a short longevity of 30-60 minutes, is compatible with fabric containing at least 90% polyester, has an expiration date of September 2014 and contains 100% "green" ingredients. The dryer sheets dispensed from the outer compartment are loaded with Brand B fragrance which has a "woody" category, has a short longevity of 30-60 minutes, is compatible with fabric containing at least 90% polyester, has an expiration date of September 2014 and contains 100% "green" ingredients.
 FIG. 6 shows a process of making a roll of the customized perfume scented dryer sheets 110 in a sealable container 300. The system has a controller 600 to control the dispensing of the containers of customized fragrance A, customized fragrance B, customized fragrance C . . . etc. Each of the containers has nozzle 610, 620, 630. The customized perfume or fragrance is spit to the dryer sheets 110 (on a running conveyor belt 650) with a precise amount. The customized perfume scented dryer sheets are then conveyed (on a running conveyor belt 660) to a packaging step 700 in order to packaging the dryer sheets into the sealable containers 300 (can be shipped as finished product in box 680).
 FIG. 7 shows an order process of buying a roll of the customized perfume scented dryer sheets in a sealable container. The buyers 710, 720, 730 can customize the order the customized perfume scented dryer sheets via the website on internet. The buyers 710, 720, 730 can customize or select the percentage (in volume) of brand name perfumes on each sheets (as shown in FIG. 5A) or number of each brand name fragrance sheets in each container (as shown in FIG. 5B).
 The customized order is then sent to the controller 600 at the manufacturer site.
 It is noted that the dryer sheet substrate is custom selected to be made of a material that is semi-absorbant specifically for the selected complex fragrance and minor additive components and will preferentially and substantially transfer all of the components to the clothing fabric during the non-heat tumble drying cycle. The particular dryer sheet substrate material to use for a given complex fragrance can be determined using published partition coefficients for the individual fragrance components, such as ClogP, etc. Also, the use of fixatives and longevity extenders is well known and can be used as additives with the fragrance components to ensure a given longevity that is identified with the indicia on the dryer sheet dispenser or individual packaging.
 As natural fragrance components become more difficult to find (e.g., certain musks and ambergris), and are being replaced with newer synthetic versions, and as manufacturing processes gradually include renewable "green" sources (i.e., vegetable oils) rather than petroleum and other fossil sources, the indicia on the packaging can include the relative amounts of these "green" components as well.
