摘要

Production of cotton warp yarns with an 'inverse denim' effect involves: (i) throughly dyeing using indigo (I) in an indigo dyeing apparatus at 30-90[deg]C and a (I) concentration of 5-500 g/l in a single dip; and (ii) selectively decolorizing the (I) at the surface of the yarn in a subsequent bleaching step. An independent claim is included for textile articles containing yarns dyed by the process.
