Abstract:
To improve the hydrophilicity of polypropylene (PP) melt-blown nonwoven materials, the surfaces of materials were treated by argon plasma and then grafted by acrylic acid because of its chemical inertness of PP. The treated nonwoven materials show good hydrophilicity. The influence of different atmosphere, processing voltage and time on plasma treatment were studied. At the same time, the influence of grafting temperature, time, and monomer concentration on acrylic acid grafted treatment were also studied. Using contact angle analyzer, scanning electron microscope (SEM) and Fourier infrared spectroscopy (FT-IR), hydrophilicity, surface morphology and group changes of materials before and after treatment were measured. The results show that under conditions of processing voltage of 150 V, the processing time of 180 s, argon plasma treatment, grafting time of 90 min, grafting temperature of 60 ℃ and acrylic monomers concentration of 60%, the sample contact angle decreased from 140 ° to 32 °, and hydrophilicity is the best.
Key words: polypropylene, melt-blownnonwowen material, plasma, graft, acrylic acid
