Summary: | 碩士 === 國立臺北科技大學 === 有機高分子研究所 === 91 === Polyester fiber is hydrophobic, after it was woven into high-density fabric, showing more hydrophobic and less practical applications. In this study, polyester fabrics were treated by plasma initiated in argon, then put into the acrylamide monomer solution. In the meantime, UV light was applied to promote graft polymerization in order to achieve good hydrophilic properties on polyester high-density woven fabric. Our study covers four approaches:(1)argon plasma-induced polyester fabrics were dipped in the acrylamide solution, then irradiated with UV light to promote graft polymerization, (2)argon plasma-induced polyester fabrics were dipped in the acrylamide solution, nipping, then irradiated with UV light to promote graft polymerization , (3)γ-ray-induced polyester fabrics were dipped in the acrylamide solution, then irradiated with UV light to promote graft polymerization,,(4)γ-ray-induced polyester fabrics were dipped in the acrylamide solution, nipping, then irradiated with UV light to promote graft polymerization . These surface properties of the modified fabrics were analyzed with grafting yield, drape, diffusion area of water droplet, contact angle of water, dyeability, FT-IR (Fourier Transfer Infrared Spectrometer) and SEM (Scanning Electron Microscope). The results indicated that γ-ray inducing / dipping / nipping /uv irradiating process imparts the best hydrophilic modification of polyester high-density fabrics with highest graft yield of 12.74% . The increase in graft yield provides the increase in dyeability and hydrophilicity of fabrics but the decrease in drape.
