Superfine fiber containing grey dope dyed component and the fabric made of the same

Abstract

A gray dope dyed superfine fiber with neutral color hue and a fabric made thereof, wherein the mono-filament denier of the gray superfine fiber is of 0.03˜0.5 denier, and the fabric formed by the gray superfine fiber may be further deeply dyed to a desired color during dyeing and finishing stage; particularly, when the fabric after deep dye shall possess not only a desired touch of soft and exquisite but also a superior quality of color fastness to dry crocking over level 4, color fastness to wet crocking over level 3, color fastness to light over level 3, color change of color fastness to laundering over level 4, and color fastness to laundering with respect to PET stain resistance over level 4 and color fastness to laundering with respect to Nylon over level 3.
