Apparatus of Fabricating Environmentally Friendly Water-Repellent Colored Fabrics

Abstract

An apparatus is provided to make fabrics. The fabrics are environmentally friendly, water-repellent and colored. A pigment, a C4 fluorine-containing compound, a dispersant and a related polymer substrate carrier are bond to obtain water-repellent colored masterbatches. The C4 fluorine-containing compound is environmentally friendly while being free of perfluorooctanoic acid (PFOA) and perfluorooctane sulphonate (PFOS). The masterbatches are spun into yarns for making a fabric with the pigment and the C4 fluorine-containing compound uniformly mixed. Thus, the present invention significantly reduces waste water pollution from dyeing and processing without generating environmentally harmful PFOA and PFOS.
