PURPOSE:To obtain the title evenly dense-colored product with high fastness by dyeing under specified conditions a knit fabric composed of worsted yarns produced by oxidation treatment of wool surface followed by shrink proofing with a specific resin. CONSTITUTION:Firstly, wool slivers are put to oxidative treatment with chlorine or oxygen, etc., to remove part of the cuticular layer on the surface and expose the hydrophilic inside layer, thus obtaining modified worsted yarns. Second, the yarns are put to shrink proofing with a polyamide epichlorohydrin resin to produce slivers, which are then spun into worsted yarns. Using the yarns, a knit with fabric is formed and then dyed in a boiling state in an alkaline dyeing solution containing such a compound as to gradually degrade in a boiling state and generate an acid (for the dye, acidic mordant, metal-contg., acidic super-milling dye, etc., is used), thus obtaining the objective evenly densecolored outerwear product with high fastness. |
