Abstract

A super-hydrophobic fiber of the present disclosure includes: a nano-needle fiber having a surface including needle-shaped nano structures; and a coating layer disposed on the surface including the nano structures, and containing a hydrophobic material. The fiber has no aging effect, and thus, is excellent in durability, and has such a large contact angle and such as small sliding angle that the fiber may not be wet with water. A method for fabricating the super-hydrophobic fiber includes: a preparation step of preparing a pre-treating fiber; an etching step of etching a surface and an inner portion of the pre-treating fiber to fabricate a nano-needle fiber having a surface on which needle-shaped nano structures are formed; and a coating step of forming a coating layer containing a hydrophobic material, and enables mass production and is performed by simple processes.Further, an article including the super-hydrophobic fiber is an article in which no liquid drop is absorbed, scarcely adsorbs a contaminant, needs not be dried, and thus, may be widely applied even to recreational articles.

Description

CROSS-REFERENCE TO RELATED APPLICAION

[0001] Pursuant to 35 U.S.C. §119(a), this application claims the benefit of earlier filing date and right of priority to Korean Application No. 10-2014-0000891, filed on Jan. 3, 2014, the contents of which is incorporated by reference herein in its entirety.BACKGROUND OF THE DISCLOSURE

[0002] 1. Field of the Disclosure

[0003] The present disclosure relates to super-hydrophobic fiber having a surface including needle-shaped nano structures and in which a coating layer containing a hydrophobic material is formed on the surface, a method for fabricating the same, and a fiber product comprising the same.

[0004] 2. Background of the Disclosure

[0005] In order to impart a hydrophobic or contamination prevention function to the conventional functional clothing, methods of coating a material having a low surface energy, such as hydrophobic Teflon have been adopted. Further, International Publication No. WO 2012 / 152997 discloses a method of forming a super-hydrop...
