Brief description of the dyeing bath in a single continuous mixtures fabrics of polyester fibres modified and wool

摘要

P dyeing process, continuous or semi - continues in a bath of fabrics mixed of wool fibers and polyester fibres with the aid of dispersed dyes and esters of leuco of dyes of the vessel by thermosol and wet development, characterized by the fact that one padded the fabric in an aqueous bath containing the coloring of the two categories, as the thermosole to 160°C - 180°C. after drying, that is left for 30 to 40 seconds in an aqueous bath at 30 degrees - 40°C. containing 5 to 10 ml / l of concentrated sulfuric acid and 0,2 to 0,5 g / l of sodium chlorite, and that it is exposed to air at ambient temperature for 1 minute, at most, and that it is used as a polyester fibers of the fibers that can be obtained without a carrier, obtained from poly (ethylene modified by alcohols, acids - or aliphatic diacids or by polyaddition of ethylene oxide with the formation of a block copolymer. / p
