  • Cellulose fibrillation
    Patent number: 8915457
    Abstract: A process for making a fibrillated blend of lyocell and cellulose pulp fibers in which a blend of lyocell and cellulose pulp fibers is provided. The lyocell is from 25% to 75% of the total weight of the blend of lyocell and cellulose pulp fibers. The blend is refined in a high shear field device to provide a blend of fibrillated lyocell and pulp fibers having a diameter of 10 to 500 nanometers and a fiber length of 50 to 500 ?m. The high shear field device can be a homogenizer or colloid mill.
