Abstract

La présente invention vise à fournir une structure de fibre qui présente un excellent caractère hydrophobe et une excellente résistance au lavage. Pour mettre en œuvre la présente invention, une structure de fibre à caractère hydrophobe dans laquelle un film de résine, qui comprend un composé d'hydrocarbure, un composé de silicone et un composé de mélamine, adhère à une surface de fibre, et la quantité totale du composé de silicone est de 1 à 50 % en masse en termes du composé contenant des hydrocarbures. Le composé d'hydrocarbure est de préférence une polyoléfine et un hydrocarbure aliphatique ayant 12 carbones ou plus, un acide carboxylique aliphatique ayant 12 carbones ou plus, et un ester de ces derniers, ou un ester d'acide (méth)acrylique présent par l'intermédiaire de liaisons esters et ayant 12 carbones ou plus dans des groupements hydrocarbures. De plus, le composé de silicone est de préférence choisi parmi un silicone modifié par amine, un silicone modifié par époxy, un silicone modifié par carboxyle, un silicone d'hydrodiène de méthyle et un silicone de diméthyle.
