| 发明名称 | Cellulose fibrillation | ||
| 摘要 | 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 μm. The high shear field device can be a homogenizer or colloid mill. | ||
