摘要：【中文】本发明涉及一种非原纤化Lyocell纤维的制备方法。所述方法包括湿纤维浸入交联溶液中，所述交联溶液为交联剂和助剂的混合溶液；取出纤维，轧制纤维，微波催化纤维，得到非原纤化纤维；所述湿纤维为未经干燥的纤维。交联剂为三嗪类化合物，助剂为碱性化合物。微波功率不低于100W。通过本发明的方法得到的Lyocell纤维具有较好的强度、伸长率等性能指标的同时具有较佳的抗原纤化特性，湿磨损次数高达2600次。 【EN】The invention relates to a preparation method of non-fibrillated Lyocell fiber. The method comprises the steps that wet fibers are immersed into a crosslinking solution, and the crosslinking solution is a mixed solution of a crosslinking agent and an auxiliary agent; taking out the fiber, rolling the fiber, and catalyzing the fiber by microwave to obtain non-fibrillating fiber; the wet fibers are undried fibers. The cross-linking agent is a triazine compound, and the auxiliary agent is an alkaline compound. The microwave power is not lower than 100W. The Lyocell fiber obtained by the method has good performance indexes such as strength, elongation and the like, and simultaneously has good fibrillation resistance, and the wet abrasion frequency is as high as 2600 times.
