A METHOD OF MANUFACTURING A FABRIC WITH A STONE-WASHED OR WORN LOOK

Abstract A method of manufacturing a yarn, fabric or garment with a stone wash or worn look, said method comprises a) coating the yarn, fabric or garment with a solution of xyloglucan polymer; b) dyeing the coated yarn, fabric or garment; and c) treating the dyed yarn, fabric or garment with an effective amount of an enzyme in an aqueous medium wherein said enzymes is capable of degrading the xyloglucan polymer, and has no or only a low activity towards insoluble cellulose.

The polymer uptake increases with increasing concentration of Polygum 55 in the coating bath. Excess polymer is removed during Che rinse procedure.
The resales from the dyeing and finishing procedure are shown in table 2. When excess polymer is sufficiently removed in a rinse procedure the dye uptake is only slightly affected by the polymer concentration, and the dye is evenly distributed on the fabric . For each concentration of; Polygum 53 a higher abrasion level is obtained when a xyloglucanase has been added during the incubation; compared to a. treatment w. thout anzyme, thus resulting in a higher delta reflection delta refled Hence, it is possible to obtain the desired abraded look on indigo dyed twill by using the new twill manufacturing dyeing method. Surprisingly, the. increase in delta reflection is not accompanied by a concomitant strength
