Abstract:
This invention relates to textile substrates to which a finishing treatment has been applied during the manufacturing process. Such a finishing treatment provides improved water and/or oil repellency and stain and soil resistance. The finishing treatment generally includes a repellent agent, a stain release agent, and a particulate component. Other compounds may be added to the treatment, such as stain-blocking agents, crosslinking agents, coupling agents, antimicrobial agents, and pH adjusting agents. The components of the finishing treatment are generally applied to the textile substrate using an application process that results in layered structures on the surface of the treated substrate, which has been found to greatly improve the durability of the treatment. Such treated textile substrates thus exhibit excellent stain and soil resistance and water and/or oil repellency properties.
Abstract:
In general terms, the present invention includes a light emitting polymeric material, the polymeric material comprising: (a) an electron transporting polymer; the electron transporting polymer in contact with (b) an electron blocking polymer, the electron blocking polymer incorporating a network electrode polymer. Such devices may be bilayer or multilayer devices, in accordance with arrangements known in the art. Likewise, the source of electrical current may be from any appropriate source having the electrical characteristics sufficient to and appropriate for the desired device make-up and application.
Abstract:
Light-emitting bipolar devices consist of a light-emitter formed from an electroluminescent organic light-emitting material in contact with an insulating material. The light emitter is in contact with two electrodes that are maintained in spaced apart relation with each other. The light emitter can be formed as an integral mixture of light emitting materials and insulating materials or as separate layers of light-emitting and insulating materials. The devices operate with AC voltage of less than twenty-four volts and in some instances at less than five volts. Under AC driving, the devices produce modulated light output that can be frequency or amplitude modulated. Under DC driving, the devices operate in both forward and reverse bias.
