A Study on the Durable Hydrophilic Finish of Synthetic Fiber (I) -The Durable Hydrophilic Finish of Synthetic Fiber with Phenol-blocked PEG-TDI Prepolymer-

This study is related to the hydrophilic finishing of synthetic fiber with phenol-blocked PEG-TDI prepolymer. The thermal properties of phenol-blocked TDI and phenol-blocked PEG-TDI prepolymer were investigated with IR spectroscopy, DTA and TGA. Phenol-blocked TDI was dissociated to phenol and TDI at 130$^{\circ}C$ under the atmosphere, and phenol-blocked PEG-TDI prepolymer was dissociated to isocyanate-terminated PEG-TDI prepolymer and phenol at 147$^{\circ}C$ Polyester fabric was padded with aqueous emulsion of phenol-blocked-TDI prepolymer and crosslinking agent such as triethanol or diethanol amine, predried, and cured at 170$^{\circ}C$. This finished polyester showed very low frictional electrostatic charge, short half-life and good wicking properties.
