<p>PURPOSE:To obtain the titled fibers having the wood grainlike surface form and improved color developing property and deep color, by dipping polyester fibers containing inert fine inorganic particles in an aqueous solution of an alkali containing chlorobenzene or an alkylnaphthalene, etc. CONSTITUTION:Polyester fibers containing 0.1-10wt% inert fine inorganic particles having <=5mu average primary particle diameter are dipped in an aqueous solution of an alkali containing 5-40wt%, based on the fiber weight, one or more compounds consisting of chlorobenzene, an alkylnaphthalene, diphenyl and phenylphenol at 110 deg.C or above to give the aimed fibers having surfaces with longitudinal streaky recesses having <=1mu width in the fiber axial direction and >=0.3mu depth and lateral streaky recesses having <=0.3mu width in the direction perpendicular to the fiber axial direction and >=0.3mu depth.</p> |
