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:
Fabrics are made electrically conductive by contacting the fiber under agitation conditions with an aqueous solution of an aniline compound, oxidizing agent and a doping agent or counter ion and then depositing onto the surface of individual fibers of the fabric a prepolymer of the aniline compound so as to uniformly and coherently cover the fibers with a conductive film of the polymerized aniline compound and wherein, furthermore, the oxidizing agent is a vanadyl compound whereby the reaction rate is controlled such that the prepolymer is uniformly and coherently absorbed onto the surface of the textile material, thereby providing improved films of electrically conductive polymerized compound on the textile material.

Textile materials comprising polyester fibers having improved durable soil release characteristics are provided by padding the textile material with an effective amount of polymer solution comprising from about 0.05 to about 5 weight percent based on the weight of the solution of a sulfonated polyester polymer, and at least about 10 percent based upon the weight of the sulfonated polyester polymer of a water-soluble salt in which the cation moiety of the salt is a polyvalent metal ion of magnesium, zinc, or calcium. The aqueous solution is padded onto the textile material in an amount sufficient to provide at least about 0.05 weight percent solids on the textile material, such solids being a combination of the sulfonated polyester and the salt constituent. The resulting wet textile material may thereafter be dried to remove substantially all of the water and thereafter the dry textile material may be heated to a temperature sufficient to heat set the fabric and cure the polymer containing the salt constituent.

摘要:
A conductive polymeric material such as a textile fabric having a conductive polymer film may be treated with a solution containing a chemical reducing agent to reduce its conductivity. By selectively reducing portions of the conductive polymer in varying degrees, a gradient of conductivity may be produced in the material. After the conductive polymer has been reduced to a target level, the reducing solution may be removed with a hot water rinse.
