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.
전방향족 폴리에스테르 (III) -용융 가공성 공중합체-

Wholly aromatic copolyesters from phenyl hydroquinone, 2,6-naphthalene dicarboxylic acid, ph-biphenyl dicarboxylic acid and l-acetoxybenzoic acid were synthesized by melt polycon- densation. Their properties were investigated by using DSC, polarizing microscope, TGA, and RDS. These copolyesters showed melt transitions at the temperature below 300℃ to give a processable nematic melt. The Tg's were closely related to the composition of the copolyesters. When the ratio of oxybenzoyl unit was increased the Tg was decreased. The fiber structures and mechanical properties of the copolyesters were observed by using SEM, X-ray diffractomer and Instron. The fibers had high orientation and good mechanical properties such as tensile strength min. 170kg/mm2 and modulus 12000kg/mm2.

Purpose: The purpose of this study was to compare body image, depression, and climacteric symptoms among middle-aged women with and without thyroidectomy. Method: The research design was a comparative descriptive study using a self-report questionnaire. A total of 102 women aged 40~59 years were recruited using a convenient sampling method. A total of 52 women out of 102 were within a year after thyroidectomy due to benign disease. The rest of the subjects were healthy women without any previous diseases in thyroid. The instruments included Body Image Concern Inventory, Climacteric symptoms, and Center for Epidemiological Studies Depression Scale. The data were analyzed by descriptive statistics, t-test, ???u -test, one-way ANOVA, and correlation analysis. Results: There were no significantly differences in age, education, menstruation states between women with and without thyroidectomy. The demographic characteristics of two groups were homogeneous. There were significantly statistical differences in body image (t= 8.456, p=.000), and depression (t=3.142, p=.002) between the groups. There was, however, no significantly differences of climacteric symptoms. In addition, in women with thyroidectomy, no significant associations were found among body image, depression, and climacteric symptoms. Conclusion: The findings demonstrated the need to develop an effective nursing intervention to increase body image and to reduce depression in middle-aged women after thyroidectomy.
Fourier Transform IR에 의한 혼방섬유의 정성 및 정량분석(II) -면 혼방품의 정량분석에의 FTIR 적용-
김갑진,윤병숙 한국섬유공학회 1986 한국섬유공학회지 Vol.23 No.3
The IR spectra of cotton, PET, nylon 6, viscose rayon, polypropylene, acrylic, acetate rayon, and cotton/A fiber blend were obtained by using a FTIR spectrometric method. These all except cotton/A fiber blend spectra were weight-nomalized to a sample weight of 2mg with the scaling function in the arithmetic command. The IR spectrum of cotton/A fiber blend was digitally subtracted with the normalized A fiber spectrum until A fiber component was removed completely i.e. the difference spectrum resembled the spectrum of cotton. When this subtracting operation was carried out, the scale factor(FCR)A, which meant the content of A fiber in cotton/A fiber blend, was also determined. After that, the difference spectrum was digitally subtracted with the normalized cotton spectrum until cotton copmponent was removed completely i.e. one could obtain the zero spectrum having the flat base line throughout all wavenumbers. When the second subtracting procedure was carried out, the scale factor(FCR)C, which meant the content of cotton in cotton/A fiber blend, was determinded. The contents of cotton and A fiber were calculated from these two scale factors. These fiber contents by FTIR were very close to the real fiber contents.
