Joint patent for high tenacity lyocell

Birla

A joint patent application has been filed by Birla Cellulose, the pulp and fiber business of the Aditya Birla Group, Mumbai/India, and Nanollose Ltd., Nedlands/Australia, for a high tenacity lyocell fiber made from bacterial cellulose.

The patent application represents a major advancement over Nanollose’s previous viscose versions of nullarbor and nufolium fibers. Using the lyocell process, nullarbor fiber has been produced that is finer than silk and significantly stronger than conventional lyocell that is traditionally based on wood pulp.
Lyocell is a form of rayon, made using a closed loop process with low demand on chemical and water usage and low waste generation. This makes it very environment-friendly. Furthermore, the combination of the Nanollose’s Tree-Free cellulose, along with Birla Cellulose’s closed-loop lyocell production process, could potentially make this Tree-Free lyocell one of the most eco-friendly and sustainable fibers available.
The joint patent application strengthens the intellectual property portfolio of both companies and provides protection for this innovative Tree-Free fiber technology. The nullarbor lyocell fibers are produced using feedstock from industrial and agricultural organic waste.
