Abstract

The invention relates to a method for improving oil absorption performance of polypropylene fibers by utilizing super-hydrophobic modification. The method comprises the following steps: S1, dissolvingcopper oxide particles in a solvent, dispersing the copper oxide particles under the action of ultrasonic waves to form a uniform copper chloride solution, soaking polypropylene fibers into the copper chloride solution, and after a continued ultrasonic action, uniformly depositing copper oxide nanoparticles on the polypropylene fibers; S2, taking out the polypropylene fibers obtained in the stepS1 from the copper chloride solution, cleaning the polypropylene fibers, putting the polypropylene fibers into an oven, and continuously heating and curing the polypropylene fibers at 60 DEG C, 70 DEGC and 80 DEG C to obtain polypropylene fibers with rough nano surfaces; and S3, preparing a palmitic acid solution with a certain concentration by using an organic solvent, immersing the polypropylene fibers obtained in the step S2 into the palmitic acid solution for a curing reaction, then fully washing the modified polypropylene fibers with an alcohol solvent, and then putting the modified polypropylene fibers into a drying oven for heating and drying at 60-80 DEG C to obtain the super-hydrophobic modified polypropylene fibers.

Description

technical field [0001] The invention belongs to the technical field of fiber material modification, and in particular relates to a method for improving the oil absorption performance of polypropylene fiber by superhydrophobic modification. Background technique [0002] With the rapid development of society and industry, the demand for oil has risen sharply, and the environmental problems caused by crude oil leakage and industrial waste oil have become increasingly serious. At present, traditional oil removal methods mainly include physical methods (sedimentation method, oil-absorbing materials), chemical methods (combustion method, demulsification method, coagulation method) and biodegradation methods. In the existing oil removal technology, the use of adsorbent materials is generally considered to be an effective and convenient method due to the special wettability of the adsorbent materials. [0003] At present, oil-absorbing materials can be divided into natural material...
