首先测试分析了山东英利产Lyocell纤维(英赛尔)的结晶度和取向度,证明其具有原纤化所需的内部结构;然后基于原纤化产生的理论条件、方法,力求在外力均匀作用的环境中,使Lyocell纤维及其制品更快、更均匀地产生超细化,分裂出超细纤维且对纤维制品的负面影响最小,最终得到超细化的具体技术方案。结果表明:Lyocell纤维在2.5 mol/L的NaOH溶液中膨润10 min后,经低能槽式超声设备处理30 min或者经高能探头式超声设备处理10 min后,均可有效地超细化,分裂成超细纤维,且超声波处理时间越长,纤维超细化程度越高。低能槽式超声设备方便用于Lyocell纤维织物的超细化处理。
First of all, the crystallinity and orientation of Lyocell fiber from Shandong Yingli Co., Ltd. were tested and proved to have the internal structure required for fibrillation. Based on the theoretical conditions and methods of fibrillation, Environment, make Lyocell fiber and its products faster and more evenly produce ultrafine, split the microfiber and minimize the negative impact on the fiber products, and finally get the superfine specific technical solutions. The results show that Lyocell fibers can be ultrafine and split effectively after being swollen in 2.5 mol / L NaOH solution for 10 min, after being treated by low-energy trough ultrasonic equipment for 30 min or by high-energy ultrasonic probe equipment for 10 min, respectively Into ultra-fine fibers, and the longer the ultrasonic treatment, the higher the degree of fiber ultrafine. Low-energy trough ultrasound equipment for the ultra-fine processing of Lyocell fiber fabric.
