Surface Mapping Of Fibers As A Screening Mechanism For Fiber Modifying Enzymes, 19TissueCon
The use of cellulase enzymes to condition fibers prior to refining is a proven science. The benefits of this approach are well known: reduction in refiner energy which gives the following benefits: increased bulk, improved softness, better drainage and so on. The search for new and better enzymes for this application can be lengthy and tedious. There are numerous techniques that have been used in this area with varying degrees of success. Buckman has begun using high throughput, automated screening techniques that yield as much if not more information than previous techniques. These techniques are more predictive than existing test methods. Furthermore, a novel characterization technique provides a better understanding of what types of cellulose and hemi cellulose are present on the surface of the fiber. This information, combined with the known activities of the enzymes, is critical to enzyme selection. This new technique has also sped product development efforts resulting in new products in this area. A description of the technique used, products developed, and case histories detailing the benefits to the tissue maker will be disclosed hereafter.
