Abstract
The present invention provides xyloglucan conjugates useful as molecular anchors for attaching various functional chemical groups to cellulose or cellulosic materials. The functional groups in the xyloglucan conjugates can serve as dyes, fabric softeners, antimicrobial agents, and flame retardants and the like. Also provided are methods of preparing and using the xyloglucan conjugates of the invention.
Claims42
A method of making a xyloglucan conjugate comprising the steps of:
- (a) preparing xyloglucan fragments from xyloglucan polymers;
- and
- (b) attaching one or more functional groups to the reducing end and/or side chains of the xyloglucan fragments whereby a xyloglucan conjugate useful for binding to cellulosic material is produced.
A xyloglucan conjugate capable of binding to cellulosic material.
A method of attaching a functional group to cellulosic material comprising the steps of:
- (a) preparing xyloglucan fragments from xyloglucan polymers by hydrolysis;
- (b) attaching one or more functional groups to the reducing end and/or side chains of the xyloglucan fragments to produce a xyloglucan conjugate;
- and
- (c) treating a cellulosic material with the xyloglucan conjugate whereby the cellulosic material containing the functional group is produced.
A method of attaching a functional group to cellulosic material comprising the steps of:
- (a) attaching one or more functional groups to the side chains of xyloglucan polymers to form modified xyloglucan polymers;
- (b) preparing a xyloglucan conjugate from the modified xyloglucan polymers of (a) by hydolysis;
- and
- (c) treating a cellulosic material with the xyloglucan conjugate whereby the cellulosic material containing the functional group is produced.
