摘要:
A fuel composition for a fuel injected internal combustion engine, a method for improving performance of fuel injectors and a method for cleaning fuel injectors for a fuel-injected internal combustion engine. The fuel composition includes a major amount of fuel and a minor, effective amount of a quaternary ammonium salt of a hydrocarbyl amine and a hydrocarbyl-substituted alkyl-hydroxybenzoate. The amount of quaternary ammonium salt present in the fuel is sufficient to improve performance of the fuel injected internal combustion engine having combusted the composition compared to the performance of such engine having combusted a fuel composition that does not contain the quaternary ammonium salt. The hydrocarbyl-substituted alkyl-hydroxybenzoate contains one or more hydrocarbyl substituents providing a total of at least 8 up to about 200 carbon atoms, provided the one or more hydrocarbyl substituents do not contain sulfur, oxygen, or nitrogen atoms.

A fuel composition for a direct fuel injected diesel engine, a method for improving performance of fuel injectors and a method for cleaning fuel injectors for a diesel engine. The fuel composition includes a major amount of fuel and a minor, effective amount of a quaternary ammonium salt having a thermogravimetric analysis (TGA) weight loss of greater than 50 wt. % at 350° C. The amount of quaternary ammonium salt present in the fuel is sufficient to improve performance of the direct fuel injected diesel engine having combusted the composition compared to the performance of such engine having combusted a fuel composition that does not contain the quaternary ammonium salt.
摘要:
The present disclosure relates to a protective garment system having two primary components. The first component, which serves as the outer layer of the garment, comprises a textile substrate that has been treated on one side with a hydrophobic composition and has been treated on the opposite side with an oleophobic composition. This combination is well-suited for protection against a variety of organic, oily type liquids (such as chemical warfare agents). The second component, which is a composite structure that serves as the inner layer of the garment, contains a core of activated carbon positioned between layers of adhesive and textile substrate.
摘要:
The present invention relates generally to substrates that exhibit useful, auto adaptable surface energy properties that depend on the environment of the substrate. Such surface energy properties provide relatively high advancing and receding contact angles for liquids when in contact with the target substrate surface. The substrates exhibit low surface energy quantities of at most about 20 millijoules per square meter (mJ/m2) at a temperature of about 25 degrees C. and a surface energy greater than about 20 mJ/m2 at, or with exposure to, a temperature of about 40 degrees C. More specifically, encompassed within the present invention are textile substrates having this highly desirable unique surface energy modification property and which exhibit wash durable oil and water repellency and stain release features. Novel compositions and formulations that impart such surface energy modifications to substrates are also encompassed within this invention, as well as methods for producing such treated substrates.

摘要:
The invention provides a treated textile material having a finish applied to at least a portion of the surface thereof. The finish comprises at least one particulate component which exhibits a positive surface charge when suspended in an aqueous medium. The invention further provides a process for producing a treated textile material comprising the steps of (a) providing a textile material having a surface, (b) providing a suspension comprising a medium and at least one particulate component, the particulate component exhibiting a positive surface charge when suspended in an aqueous medium, (c) applying the suspension to at least a portion of the surface of the textile material, and (d) heating the textile material to remove the medium from the textile material and produce a finish comprising the particulate component on the surface of the textile material.
摘要:
Wash-durable fluorochemical-containing textile and/or fiber treatments that simultaneously impart soil resistance (or soil-release) properties and moisture wicking characteristics to target fabric substrates are provided. Such treatments surprisingly impart these two simultaneous effects to target fabrics and/or fibers because fluorochemicals generally provide moisture repellency rather than moisture wicking capabilities. As prior soil release/moisture wicking treatments do not function properly, or, alternatively, compromise hand or other properties of certain target textiles after treatment application, a new, effective, soil release/moisture wicking formulation for such purposes was needed. The inventive treatment is extremely durable on such fabric substrates; after a substantial number of standard launderings and dryings, the treatment does not wear away in any appreciable amount and thus the substrate retains its soil release/moisture wicking properties. The method of adherence to the target yarn, fiber, and/or fabric may be performed any number of ways, most preferably through the utilization of a jet dyeing system or through a steam-transfer method. The particular methods of adherence, as well as the treated textile fabrics and individual fibers are also encompassed within this invention.

A method cleaning up internal components of a fuel injector for a diesel engine. The method includes operating a fuel injected diesel engine on a fuel composition that includes a major amount of diesel fuel and from about 5 to about 500 ppm by weight of a reaction product derived from (a) a hydrocarbyl substituted dicarboxylic acid, anhydride, or ester and (b) an amine compound or salt thereof of the formula wherein R is selected from the group consisting of hydrogen and a hydrocarbyl group containing from about 1 to about 15 carbon atoms, and R1 is selected from the group consisting of hydrogen and a hydrocarbyl group containing from about 1 to about 20 carbon atoms. The reaction product is characterized by a particular FTIR spectrum.
