고상공정법(SSP)에 의한 고강도폴리에틸렌(HSPE) 섬유의 제조는 초고분자량 폴리에틸렌 분말의 압출과 연신으로 용매를 사용하지 않고 제조된다. 고상공정으로 제조된 고강도 PE 테이프사의 특성을 분석한 결과, 고강도 PE 테이프사는 여신비의 증가에 따라 인장강도가 증가하였고, 파단면에서 fibril 분리현상이 많이 생겼다. 고강도 PE 테이프사의 표면을 산소플리즈마로 처리하여, 표면에너지를 측정하였고, 수지와 계면결합력을 분석한 결과, 100W와 5분간의 플라즈마 처리에서 가장 높은 계면결합력을 나타내었다. 고강도 PE 테이프사 강화복합재료의 물성을 겔방사법으로 제조된 고강도 PE 섬유강화 복합재료의 물성과 비교하여 고찰하였다.

Three super hydrophobic fluorescence dyes were selected to dye high molecular weight polyethylene fiber and their molar absorptivity, emission spectrum, and quantum yield were measured. From the results of color strength on the fiber, all the three dyes exhibited linear increase according to the dye concentration and Fluoro3 dye showed the highest color strength among them. Emission strength of the fluorescence dyes on the fiber was investigated according to the dye concentrations. The emission was increased with the increase of the dye concentration at relatively low dye concentration and then after showing the maximum emission strength the emission was decreased at higher dye concentrations. The highest emission was obtained in Fluoro2 dye. Color fastness to washing and rubbing was generally good enough, however, especially to light, only Fluoro3 dye exhibited rating 3 acceptable practically and Fluoro1 and 2 was ratings 1 which is unacceptable level.
