초록

This study was carried out with the view of fundamental investigating to improve the tactile and the hygroscopicity of Poly (ethylene terephthalate) (PET) fibers. Mono-sodium ethylene glycolate in ethylene glycol (MSEG-EG) solution was prepared and PET films were treated with it. The following conclusions were obtained. 1. The tensile strength decreased with increasing decomposition ratio while density, crystallinity and crystallite size increased with increasing decomposition ratio when PET films were treated with MSEG-EG solution. 2. Number of carboxyl end groups was increased until 10-20% decomposition ratio when PET films were treated with MSEG-EG solution. However, the decomposition ratio became more than 20%, the number of carboxyl end groups had tendency to decreased. 3. The surface tension of PET films increased for treating with MSEC-EG solution. Hydrogen bonding force and poler force among the components of surface tension increased while dispersion force among those decreased. 4. The moisture region of PET films increased with increasing decomposition ratio when PET films were treated with MSEG-EG solution.
