Abstract
Garment, e.g. a new pair of jeans, made from dyed twill fabric and having localised variations in the colour density of the fabric providing the jeans with a stone-washed or abraded look corresponding to a delta remission value (.DELTA.R) higher than 11, and a reflection of a first area of the jeans fabric of less than 12%, the reflection and .DELTA.R value being determined by a) measuring the reflection of the first and a second area of the fabric at a wavelength of 420 nm using a reflectometer having a measuring diaphragm with a diametrical dimension of 27 mm, the first area being located within the area of the upper half of the zipper cover visibly having the highest colour density (i.e. being relatively more coloured), and the second area being located at least about 5 cm from any stitching present on the jeans, b) expressing the reflection in % related to a white standard (100% reflection), and c) calculating the .DELTA.R value as the difference between the % reflection of the first and the second area, respectively; and a process for the manufacturing of such garments.
