维纶实际生产能力不到设备能力的一半,质量不能满足需求。利用现代测试手段深入研究成型过程中维纶纤维结构和性能的关系,提出解决途径是十分有益的,利用电镜研究了成型的主要工艺过程中(出喷丝头后的拉伸16％、湿热拉伸、干热拉伸、热水卷缩、缩醛化工艺)纤维的表现形态、结晶性、热性质和力学性能、电镜的图象和其他测试结果十分吻合,认为现有维纶工艺中的热水卷缩对结晶性有一定的破坏作用,醛化工艺耗费较大,但 The actual production capacity of vinylon is less than half the capacity of the equipment, the quality can not meet the demand. It is very beneficial to study the relationship between the structure and properties of vinylon fibers during the molding process by means of modern testing methods. It is very helpful to propose a solution to this problem by means of electron microscopy. In the main process of forming (16% elongation after spinneret spinning, , Dry heat stretching, hot water crimping, acetalization) fiber morphology, crystallinity, thermal properties and mechanical properties, electron microscopy images and other test results are very consistent that the existing vinylon hot water Crimping has some damage to the crystallinity, the hydroformylation process consumes more, however
