| Title of Invention | 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. |
| Full Text | The present invention relates to a new method of manufacturing afabric or a garment with a stone washed worn look resulting in no or very limited strength loss of said fabric or garment. gockets of garments. Consequently, reduction or climination of plant Journal, 3, pp 1.30) . Species-specific differences occur as to the distribution 4 kg Indigo rein BASF Pulver K Several other desizing methods known in the art may metabisulphite/1 for 10 min, at 50 C. A short rinse is weight loss/gain prior and subsequent to the rinse procedure respectively. 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 We claims 1. A method of manufacturing, with a very limited strength less, a fabric with a stone-washed or worn look comprising (a) coating the yarn with a biodegradable polymer by 9. A method according to claims 7 or 8, wherein the vat dye is performed with an amylase. treatments bleaching, over-dyeing, brightening, softening, or an anti-wrinkling treatment. 32. A method of manufacturing, with a very limited strength loss, a fabric with a stone-washed or worn look substantially as hereinbefore described• 33. A xyloglucan polymer substantially as hereinbefore described. 34. An enzyme substantially as hereinbefore described. |
