The present invention relates to textile articles and clothing such as outdoor garments, indoor garments, and commercial protective wear exposed to contact mixtures of water and oil, swimwear and winter wear exposed to mixtures of water and air. At least part of these textile articles possess a surface provided with at least one of 1) a high surface area, 2) hierarchical pattern, 3) contact angles such that hydrophilic portion of a contact mixture possesses a high contact angle and the hydrophobic portion of a contact mixture possesses a low contact angle, and 4) hysteresis angle greater than 5 degrees. Hydrophobic/Hydrophilic contact mixtures of the present invention can be surfaces where water and or ice are present in combination with oil and or air. The textile articles of the present invention resist slippage on surfaces possessing hydrophobic/hydrophilic contact mixtures.
An article comprising a microstructured surface capable of forming an adhesion to a contact surface wherein the microstructured surface comprises a plurality of microtextured islands each comprising a hierarchical pattern including at least a plurality of first microfeatures and at least a plurality of second microfeatures, the plurality of second microfeatures disposed about the plurality of first microfeatures, wherein the hierarchical pattern is configured to develop a hydrophobic/hydrophilic mixture when in contact with a liquid interface, such that the hydrophobic portion of the mixture associates with at least one of the plurality of first microfeatures or the plurality of second microfeatures, and the hydrophilic portion of the mixture associates with the microfeatures that do not develop the hydrophobic portion, and wherein adhesion occurs when the shear stress exceeds a normal force and the microstructured surface comprises a hysteresis angle of greater than 5 degrees.
An article comprising a microstructured surface formed on a thin film capable of generating adhesion via a liquid interface to a contact surface wherein the microstructured surface comprises a plurality of microtextured islands each comprising a hierarchical pattern including at least a plurality of first microfeatures and at least a plurality of second microfeatures, the plurality of second microfeatures disposed about the plurality of first microfeatures, wherein the hierarchical patters is configured to develop a hydrophobic/hydrophilic mixture when in contact with the liquid interface, such that the hydrophobic portion of the mixture associates with at least one of the plurality of first microfeatures or the plurality of second microfeatures, and the hydrophilic portion of the mixture associates with the microfeatures that do not develop the hydrophobic portion, and wherein adhesion occurs when the shear stress exceeds a normal force and the microstructured surface comprises a hysteresis angle of greater than 5 degrees.
