SURFACE MODIFICATION OF POLYPROPYLENE MICROFIBRE BY PLASMA-INDUCED VAPOR GRAFTING WITH ACRYLIC ACID

Received Date: 24 December 1997

The hydrophilicity, dyeing and antistatic ability of polypropylene microfibre (PPMF) wereimproved by plasma-induced vapor grafting with acrylic acid. The effects of plasma discharge time, power,liquid phase acrylic acid temperature and environmental temperatore on grafting yield were investigated. Theexistence of grafted polyacrylic acid (PAA) was verified by ESCA and ATR FT-IR. The morphology ofgrafted PAA was directly observed by SEM. The wicking test shows that the hydrophilicity of modified PPMF is greatly enhanced.The dyeability test of modified PPMF was carried out using Dispersion Yellow.It was found that the dye uptake ratio is linear to the weight percent of grafting.The antistatic ability was indicated by specific resistance.The specific resistance of modified PPMF was reduced to 106～107Ω·cm,thus the antistatic ability was considerably improved.
