摘要： Porous cellulose beads are prepared by distributing droplets of a solvent mixture containing a cellulose derivative into a precipitating solution to form porous beads which are then washed and hydrolyzed to form porous cellulose beads. The porous cellulose beads, which may be cross-linked, if desired, by suitable treatment, are useful carriers to which enzymes can be immobilized. The beads may also be used for the separation of enzymes, proteins, nucleic acids and the like, or to remove metal ions from dilute mining solutions.

摘要： The present invention relates to the production of high tensile strength, solvent-spun cellulose fiber which is stable in alkaline solutions. More particularly, the invention relates to a process in which cellulose is solubilized in a zinc chloride solution then extruded into a coagulation medium in which the cellulose fibers form. The fibers are removed from the coagulation medium, treated to remove the coagulation medium, stretched and recrystallized in water, thus forming the high tensile strength, solvent-spun cellulose fibers.
摘要翻译：本发明涉及在碱性溶液中稳定的高拉伸强度的溶剂纺丝纤维素纤维的生产。更具体地说，本发明涉及一种方法，其中将纤维素溶解在氯化锌溶液中，然后挤出成纤维素纤维形成的凝固介质。将纤维从凝固介质中除去，经处理以除去凝固介质，在水中拉伸和重结晶，从而形成高拉伸强度的溶剂纺丝纤维素纤维。
