Blue dyed polyurethane fiber containing ultramarine blue pigment mass

摘要

Blue dyed polyurethane fiber mass containing pigment ultramarine blue to this invention describes a blue dyed polyurethane fiber mass containing a pigment ultramarine blue, which is manufactured by adding a polymer of polyurethane containing a pigment ultramarine blue before a Spinning process.More specifically, it is used ultramarine blue, which is pre treated with an acid solution or a basic solution, or is pre treated through an electrochemical process using an apparatus of plasma or a device of radiation.The blue dyed polyurethane fiber mass manufactured using a pigment of this type presents a value b * equivalent to or smaller than - 2.0 and its fundamental properties, including strength and elongation, similar to those of conventional polyurethane fibre, and has a resistance. Higher than the washing, 4 - 5 points.
