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.

The composition imparts excellent water and oil repellency through cold cure.
摘要:
An industrial textile including a polymeric substrate and a resin system grafted onto the polymeric substrate by way of a primer. The resin system includes a water-borne thermoplastic, a polyhydroxyether resin and/or an analogue of a polyhydroxyether resin, and at least one co-resin.
摘要:
This invention provides compositions for treating fibrous substrates to render those substrates durably repellent to water and oil and durably resistant to dry soil comprising a 1) fluorochemical urethane formed by reacting a tri- or higher order isocyanate with a fluorochemical monofunctional compound and optionally a non-fluorinated aliphatic monofunctional compound; and 2) a fluorochemical polymeric surfactant.The present invention also provides a method of treating fibrous substrates to render those substrates durably repellent to water and oil and durably resistant to dry soil comprising application of the aforementioned composition to a fibrous substrate with optionally one or more stainblocker compounds such as acrylic and methacrylic acid polymers and copolymers, sulfonated phenol-formaldehyde resins, and styrene-maleic anhydride polymers and copolymers, said application of the composition taking place either coincident with or following application of the hydrophilic anti-staining compound or compounds to the substrate. Fibrous substrates treated according to this method and fibrous substrates treated with the aforementioned compositions are also disclosed.
摘要:
The present invention provides a method of treating a nonwoven fabric to provide the fabric with repellency to fluids while minimizing impact to the hydrostatic head properties of the fabric. Generally, the process includes contacting a nonwoven fabric with an aqueous treatment solution that includes a fluoropolymer and a polymeric antistatic agent.
摘要:
Aqueous dispersions comprising polyorganosiloxanes having relatively long alkyl groups and having aromatic groups and also polymers having perfluoroalkyl groups or fluorine-free polyurethanes are useful for treating textile fabrics.
摘要:
The present invention provides an aqueous composition comprising (i) a fluorochemical compound and (ii) an ester derivative of an alpha-hydroxy acid, the ester derivative having a melting point of not more than 35° C. and a water solubility of not more than 10% by weight at 25° C. The fluorochemical compound is typically dispersed or emulsified in the aqueous composition. The aqueous compositions may provide such advantages as providing good oil- and/or water repellency properties to a substrate upon application at ambient conditions, without the need for a heat treatment. Thus, the aqueous compositions may be used to provide oil- and/or water repellency properties to a substrate such as for example a fibrous substrate, e.g., leather or textile. In particular, repellency properties comparable to those achieved with a heat treatment step may be achieved.
