Title:
METHOD FOR BLEACHING VEGETABLE FIBER BUNDLE
Document Type and Number:
Japanese Patent JP2004027423
Kind Code:
A
Abstract:
To provide a method for bleaching a vegetable fiber bundle by which the fiber bundle can be bleached well by lignin degradation without damaging toughness and flexibility which are excellent characteristics of the vegetable fiber bundle.
The vegetable fiber bundle is bleached by degrading lignin contained in a binder of the vegetable fiber bundle while evading the degradation of pectin which is an essential component of the binder by an enzymic degradation treatment which selectively carries out a lignin degradation reaction by using a specific mediator activated by an enzyme, and an alkali extraction treatment under a mild condition under which the main component of the binder of the vegetable fiber bundle is not degraded.
