摘要： An oil-in-water emulsion that is environmentally friendly and also exhibits antimicrobial activity is provided. More specifically, the oil phase of the emulsion includes a botanical oil derived from a plant (e.g., thymol, carvacrol, etc.). Because the botanical oil tends to leach out of the emulsion during storage and before it is used in the desired application, a water-dispersible polymer is also employed in the aqueous phase of the emulsion to enhance long term stability of the oil and, in turn, antimicrobial efficacy. Without intending to be limited by theory, it is believed that the water-dispersible polymer can effectively encapsulate the botanical oil within the emulsion and inhibit its premature release. Once the emulsion is formed, water can then be removed so that it becomes a substantially anhydrous concentrate. In this manner, the water-dispersible polymer will not generally disperse before use and prematurely release the botanical oil. When it is desired, moisture may simply be re-applied to the concentrate to disperse the polymer and activate the release of the botanical oil. Of course, to provide the optimum degree of biocompatibility, the water-dispersible polymer is also a "biopolymer" that is biodegradable and/or renewable.
摘要翻译：提供对环境友好并且还显示出抗微生物活性的水包油乳液。更具体地说，乳剂的油相包括来源于植物的植物油（例如百里酚，香芹酚等）。由于植物油倾向于在储存过程中以及在用于所需应用之前浸出乳液，因此在乳液的水相中也使用水分散性聚合物以增强油的长期稳定性，并且反过来，抗菌功效。不受理论限制，认为水分散性聚合物可以有效地将植物油包封在乳液中并且抑制其过早释放。一旦形成乳液，就可以除去水，使其变成基本上无水的浓缩物。以这种方式，水分散性聚合物在使用前通常不会分散并过早地释放植物油。当需要时，可以简单地将水分重新施加到浓缩物上以分散聚合物并激活植物油的释放。当然，为了提供最佳的生物相容性，水分散性聚合物也是可生物降解和/或可再生的“生物聚合物”。

摘要： A method for forming a composition that includes mixing an antimicrobially active botanical oil (e.g., thymol, carvacrol, etc.) and a modified starch polymer within a melt blending device (e.g., extruder) is provided. Unlike the problems associated with proteins, the use of starch polymers allows for a greater degree of flexibility in the processing conditions and is still able to achieve good properties in the resulting composition. The present inventors have also discovered that a plasticizer may be employed to facilitate melt processing of the starch, as well as to enhance the ability of the botanical oil to flow into the internal structure of the starch where it can be retained in a stable manner. The composition is also typically generally free of solvents. In this manner, the starch will not generally disperse before use and prematurely release the botanical oil. Due to the water sensitivity of the modified starch, however, it may be subsequently dispersed by moisture when it is desired to release the botanical oil.
摘要翻译：提供了一种形成组合物的方法，其包括在熔融共混装置（例如挤出机）中混合抗微生物活性植物油（例如百里酚，香芹酚等）和改性淀粉聚合物。与蛋白质相关的问题不同，淀粉聚合物的使用允许在加工条件下具有更大程度的柔性，并且仍能在所得组合物中获得良好的性能。本发明人还发现，可以使用增塑剂来促进淀粉的熔融加工，以及提高植物油流入淀粉内部结构的能力，其中它可以以稳定的方式保留。组合物通常通常也不含溶剂。以这种方式，淀粉通常不会在使用前分散并且过早地释放植物油。然而，由于改性淀粉的水敏感性，当需要释放植物油时，随后可以通过水分分散。

摘要： A thermoplastic polymer composition with a tertiary blend of a carbon dioxide-derived polymer, a thermoplastic cellulose derivative, and a thermoplastic compatibilizer is described. The composition can be melt-processed into flexible, thin films that have fine nano-scale structural features in both the cross-directional and machine-directional orientations, for use in various products. The films, which are made from relatively brittle materials, exhibit a greater degree of ductility, elongation capacity, and strength than the primary, original component materials as binary -blends from which the film is made.

摘要： Fibrous articles are disclosed containing an additive composition. The additive composition, for instance, may include a water-soluble film forming component and water-soluble modifying components that is deposited at least at the surface of a fibrous web. In some aspects, the additive composition includes polymers that demonstrate a certain LCST and melting temperature. In another aspect, the additive composition is applied to the fibrous web during the heated drying phase, such as with a Yankee dryer. The fibrous web with additive composition is then creped. The additive composition may improve the perceived softness of the web without substantially affecting the absorbency of the web in an adverse manner.

摘要： A biodegradable packaging film is provided. The film is formed from a blend that contains a thermoplastic starch and polylactic acid. Starch is a relatively inexpensive natural polymer that is also renewable and biodegradable. Polylactic acid is likewise an inexpensive synthetic polymer that is biodegradable and renewable, yet also capable of providing increased tensile strength to the film. Although providing a good combination of biodegradability/renewability and increased tensile strength, the polylactic acid is also relatively rigid and can result in films having a relatively high stiffness (e.g., high modulus of elasticity) and low ductility. While more ductile than polylactic acid, the thermoplastic starch is often difficult to melt process in film forming processes and very sensitive to moisture and water vapor, reducing its ability to be used as a stand alone packaging film. In an effort to counteract the effect of such polymers, an aliphatic-aromatic copolyester is also employed in the blend of the present invention. While such copolyesters are biodegradable, they also possess the melt properties and ductility that lend them well to the formation of films. Although the combination of these polymers may achieve a good balance between biodegradability/renewability, high tensile strength, and good ductility (e.g., high peak elongation), it is still often difficult to achieve a precise set of mechanical properties as desired for packaging films. In this regard, the blend also contains a filler. Due to its rigid nature, the amount of the filler may be readily adjusted to fine tune the blend to the desired degree of ductility (e.g., peak elongation) and stiffness (e.g., modulus of elasticity).
摘要翻译：提供可生物降解的包装膜。该膜由含有热塑性淀粉和聚乳酸的共混物形成。淀粉是一种相对便宜的天然聚合物，也是可再生的和可生物降解的。聚乳酸同样是廉价的合成聚合物，其是可生物降解和可再生的，并且还能够为膜提供增加的拉伸强度。虽然提供了生物降解性/可再生性和增加的拉伸强度的良好组合，但是聚乳酸也是相对刚性的，并且可以导致具有相对高刚度（例如高弹性模量）和低延展性的膜。虽然比聚乳酸更具延展性，但是热塑性淀粉在成膜过程中通常难以熔化，对水分和水蒸汽非常敏感，降低了其作为独立包装膜使用的能力。为了抵消这种聚合物的作用，脂肪族 - 芳族共聚酯也用于本发明的共混物中。虽然这种共聚酯是可生物降解的，但是它们也具有熔融性能和延展性，使其很好地形成膜。虽然这些聚合物的组合可以在生物降解性/可再生性，高拉伸强度和良好的延展性（例如高峰值伸长率）之间达到良好的平衡，但是通常难以实现包装膜所需的精确的机械性能。在这方面，混合物还含有填料。由于其刚性，可以容易地调整填料的量以将共混物微调至期望的延展性（例如，峰值伸长率）和刚度（例如弹性模量）。

摘要： A fiber formed from a thermoplastic composition that contains a thermoplastic starch and an aliphatic-aromatic copolyester is provided. The copolyester enhances the strength of the starch-containing fibers and also facilitates the ability of the starch to be melt processed. Due to its relatively low melting point, the aliphatic-aromatic copolyester may also be extruded with the thermoplastic starch at a temperature that is low enough to avoid substantial removal of the moisture found in the starch. Furthermore, the aliphatic-aromatic copolyester is also modified with an alcohol so that it contains one or more hydroxyalkyl or alkyl terminal groups. By selectively controlling the conditions of the alcoholysis reaction (e.g., alcohol and copolymer concentrations, temperature, etc.), the resulting modified aliphatic-aromatic copolyester may have a molecular weight that is relatively low. Such low molecular weight polymers have the combination of a higher melt flow index and lower apparent viscosity, which is useful in a wide variety of fiber forming applications, such as in the meltblowing of nonwoven webs.
摘要翻译：提供由含有热塑性淀粉和脂肪族 - 芳香族共聚酯的热塑性组合物形成的纤维。共聚酯增强了含淀粉纤维的强度，并且促进了淀粉熔融加工的能力。由于其相对低的熔点，脂肪族 - 芳族共聚酯也可以在足够低的温度下与热塑性淀粉一起挤出，以避免显着除去在淀粉中发现的水分。此外，脂族 - 芳族共聚酯也用醇改性，使得其含有一个或多个羟烷基或烷基端基。通过选择性地控制醇解反应的条件（例如醇和共聚物浓度，温度等），所得改性的脂肪族 - 芳族共聚酯的分子量可以相对较低。这种低分子量聚合物具有更高的熔体流动指数和较低的表观粘度的组合，其可用于各种各样的纤维形成应用中，例如在非织造纤维网的熔喷中。

摘要： A film formed from a water-soluble polymer matrix within which is contained at least one fragrance is provided. The film is water-sensitive (e.g., water-soluble, water-dispersible, etc.) so that upon contact with a sufficient amount of water, the polymer matrix loses its integrity over time to increasingly expose the fragrance to the ambient environment for releasing its odor. The ability to incorporate a fragrance into the polymer matrix is achieved in the present invention by controlling a variety of aspects of the film construction, including the nature of the fragrance, the nature of the water-soluble polymer, the manner in which the polymer matrix and fragrance are melt processed, etc. For example, the fragrance may be injected directly into the extruder and melt blended with the water-soluble polymer. In this manner, the costly and time-consuming steps of pre-encapsulation or pre- compounding of the fragrance into a masterbatch are not required. Furthermore, to obtain a balance between the ability of the fragrance to release the desired odor during use and likewise to minimize the premature exhaustion of the odor during melt processing, the fragrance is selected to have a boiling point (at atmospheric pressure) within a certain range, such as from about 125°C to about 350°C.

摘要： A film that is both elastic and water-sensitive (e.g., water-soluble, water-dispersible, etc.) in that it loses its integrity over time in the presence of water is provided. To achieve these dual attributes, the film contains an olefinic elastomer and a water-soluble polymer. Although these polymers are normally chemically incompatible due to their different polarities, the present inventors have discovered that phase separation may be minimized by selectively controlling certain aspects of the film, such as the nature of the polyolefin, water-soluble polymer, and other film components, the relative amount of the film components, and so forth. For example, certain water-soluble polymers may be selected that have a low molecular weight and viscosity to enhance their melt compatibility with nonpolar polyolefins. This, in turn, may result in a film that is generally free of separate phases, which would otherwise limit the ability of the water-soluble polymer to contact water and disperse.
摘要翻译：提供了具有弹性和水敏性（例如水溶性，水分散性等）的膜，因为它在水的存在下随时间失去其完整性。为了实现这些双重属性，膜含有烯烃弹性体和水溶性聚合物。虽然这些聚合物由于其极性不同而通常是化学上不相容的，但是本发明人已经发现，通过选择性地控制膜的某些方面，例如聚烯烃，水溶性聚合物和其它膜组分的性质，可以使相分离最小化，膜成分的相对量等。例如，可以选择某些具有低分子量和粘度的水溶性聚合物，以提高它们与非极性聚烯烃的熔融相容性。这又可能导致通常没有分离相的膜，否则这将限制水溶性聚合物与水接触并分散的能力。
