Embodiment 1

[0115] Prepare 200 grams of a bath containing the following chemicals:

[0116] 1.9 grams of Unidyne TG-992, purchased from Daikin's fluorinated hydrophilic detergent;

[0117] 2.3 grams of Repearl F8025, a fluorinated anti-stain agent from Mitsubishi Corporation; and

[0118] 3.3.6 grams of Repearl MF, a hydrophobic block diisocyanate crosslinking agent purchased from Mitsubishi Corporation.

[0119] 100% microdenier polyester fabric was treated with the chemical composition according to the previous one-step application procedure. The chemical composition has a moisture pick-up of about 60% on fabric.

[0120] Polyester fabrics were obtained from Milliken & Company, Spartanburg, South Carolina. The fabric comprises textured polyester 1 / 140 / 200 denier warp yarns woven together with textured polyester 1 / 150 / 100 denier weft yarns in a 2 by 2 backhand twist pattern with 175 warp yarns and 80 weft yarns per inch of fabric (in the present invention hereinafter specifically ref...

Abstract

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.

Description

[0001] This application is a divisional application of Chinese Patent Application No. 03825787.4 filed on August 27, 2003 with the title of "composition and treated substrate with reversible adaptable surface energy performance and its manufacturing method". technical field [0002] The present invention is primarily concerned with substrates exhibiting useful, self-adapting surface energy properties dependent on the environment of the substrate. This surface energy property provides relatively high advancing and receding contact angles for liquids when in contact with the target substrate surface. Specifically, at a temperature of about 25°C, the substrate exhibits a maximum of about 20 mJ / m as measured by goniometric methods and calculated by the Fowkes equation 2 (mJ / m 2 ), exhibiting a low surface energy of greater than about 20 mJ / m at or when subjected to a temperature of about 40°C 2 of surface energy. This unique ability of the surface to self-modify, in turn, provi...
