PP fiber surface modification method
The invention discloses a PP (polypropylene) fiber surface modification method. The preparation method comprises the following steps: step 1, soaking PP fibers with absolute ethyl alcohol, washing and drying to constant weight to obtain PP fibers; 2, deionized water, absolute ethyl alcohol and a silane coupling agent are subjected to ultrasonic mixing, and a silane coupling agent solution is prepared; step 3, weighing the dried PP fiber, and soaking the PP fiber in a prepared silane coupling agent solution; taking out the PP fiber, washing with deionized water, filtering, drying, cooling to room temperature, and then drying the PP fiber to constant weight; step 4, preparing a nano calcium carbonate dispersion solution; and step 5, weighing the PP fiber treated by the silane coupling agent, putting the PP fiber into the prepared nano calcium carbonate solution, fishing out the reacted PP fiber, washing the PP fiber with absolute ethyl alcohol, filtering and drying to obtain the final modified PP fiber. The method is used for improving the surface roughness of PP fibers, improving the hydrophilicity and improving the performance of active groups on molecular chains.
本发明公开了一种PP纤维表面改性方法，包括以下步骤；步骤1，用无水乙醇将PP纤维浸泡，洗涤干燥至恒重，得到PP纤维；步骤2，将去离子水:无水乙醇:硅烷偶联剂进行超声波混合，配制硅烷偶联剂溶液；步骤3，称取所述干燥后的PP纤维，放入配制好的硅烷偶联剂溶液中浸泡；取出PP纤维用去离子水洗涤、过滤，并干燥，冷却至室温，然后将PP纤维干燥至恒重；步骤4，配制纳米碳酸钙分散溶液；步骤5，称取经硅烷偶联剂处理后的PP纤维放入配制好的纳米碳酸钙溶液中，将反应后的PP纤维捞出并用无水乙醇洗涤，过滤与干燥即得最终的改性PP纤维。本发明用于改善PP纤维表面粗糙程度、提高亲水性、增加分子链上活性基团的性能。
