Abstract
提供了一种在适合漂白非棉纤维素纤维、纱线或织物的条件下,通过将半纤维素酶与所述纤维、纱线或织物接触一定时间来漂白所述纤维、纱线或织物的方法。A method for bleaching non-cotton cellulose fibers, yarns or fabrics by contacting hemicellulase with said fibers, yarns or fabrics for a certain period of time under conditions suitable for bleaching said fibers, yarns or fabrics method.
Description
Background of invention
1. invention field
The present invention relates to a kind of enzyme method for bleaching of the fabric based on natural non-cotton cellulosic.Specifically, the present invention relates to use the method for enzyme Holland, flax, jute, ramie and textile-like with cracking xylan activity.
2. background technology
The enzyme treatment of cellulose fabrics has been obtained very big success industrial.Especially COTTON FABRIC, particularly COARSE DRILL cloth are industrial in the procedure of processing of these textiless, substitute as chemically treated as adopting cellulase in sand washing, biological polishing and the depilation (depilling).In addition, amylase has been used as desizing agent.Oxidoreducing enzyme also is proposed in and is used to bleach the purpose of reducing with the dyestuff transmission in the textile industry.
The washing industry has also adopted enzyme to be applied to wash dirty fabric and clothing as useful reagent, and prior art is included in and is extensive use of protease, cellulase and amylase in the detergent compositions.For example, describing protease composition is useful removing the albumen spot from fabric.In addition, in order to remove the spot on the fabric or to provide other characteristics of wanting, cellulase, amylase, at, lipase, peroxidase, oxidizing ferment and zytase (WO 98/39402) have been advised in laundry detergent compositions, using to laundering of textile fabrics.
Xylan is a kind of heteropolymer of complexity, mainly is made of wood sugar and arabinose.The xylan of terrestrial plant is by β-1, and 4-connects-D-xylopyranose main chain formation, and it can be replaced by acetyl residue, arabinose residue and methylglucuronic acid residue.Xylan is the abundant sugar of content in cellulose artifact circle second that continues.The complete hydrolysis xylan needs many enzymes, and wherein hemicellulase obtains the most extensive approval.
For example, in pulp and paper industry, hemicellulase has been used to the bleaching of paper pulp, with dosage that reduces chemicals in the blanching step subsequently or the brightness that increases paper pulp.(TAPPI can report, 1-5 (1998) for Kantelinen etc., international bleaching meeting; Viikari etc., paper and timber (Paper and Timber) 7:384-389 (1991)).This usage also further is considered to not to the prejudicial cellulose lytic activity of cellulose fibre.At PCT publication number WO 89/08738, further described this usage in pulp and paper industry among WO 91/02791 and the WO 91/05908.Hemicellulase is proposed also that to be applied to Wood Adhesives from Biomass be fuel (Viikari etc., " commercial Application of hemicellulase ", the bio-transformation of forestry and agricultural wastes, Saddler, J.ed., CAB International, USA (1993)) and feed addictive.
