Abstract:Biodegradable Tencel ultrafine fibrils were prepared by pretreatment and fibrillation of Tencel fibers.The biodegradable Tencel ultrafine fibrils had higher specific surface area and smaller average diameter, the specific surface area could reach 6.43 m2/g and the average diameter was 414 nm. The microfiltration membrane for the experiment was prepared by wet forming process using the mixed Tencel ultrafine fibrils and PET fibers in a certain proportion. Compared with no fibrillarized Tencel ultrafine fibrils, when 20% fibrillarized Tencel ultrafine fibrils (fibers-3) were added to the microfiltration membrane, the uniformity index of the membrane decreased significantly from 67.1 to 35.7, and the average pore size decreased from 11.37 μm to 3.14 μm, tensile strength increased from 334 N/m to 1180 N/m. |
