테트라메틸실란의 플라즈마 중합에 의한 폴리에스테르 직물의 농색화 가공 = Color Depth of Dyed Polyester Fabric by Plasma Polymerization of Tetramethylsilane

다국어 초록 (Multilingual Abstract)

We investigated the effect of the thin film by plasma polymerization on color depth of polyester(PET) fabric. We obtained the plasma polymerized tetramethylsilane(PP-TMS) on the fabric by the 13.56MHz RF glow-discharge method using tetramethylsilane(TMS) monomer, This monomer shows lower refractive index(n,: 1.3585)than that of polyester fabric(nv= 1.725). The chemical structure and the optical characteristic of PP-TMS have been studied with a control of discharge power W and feed-in rate of monomer Fm. From IR spectra, we observed that Si-H and Si-CHa-Si bonds were newly generated in PP-TMS, and the relative absorbance ratio of Si-CH2-Si (1045cm-1) onto CHI(1255cm-1) was gradually increased with the value of composite energy W/Fm. PP-TMS showed high hydrophobicity, and surface energy(32~36dyne/cm2) was increased with W/Fm value. We could know that the reflectance(%) and L value of the PET fabric plasma polymerized with TMS were lower than those of untreated PET fabric. From those results, PP-TMS coatings were effective on the color depth of PET fabric and these phenomena could be explained by optical theories relating to surface reflection.
