Abstract

The purpose of this study was to investigate the mechanical properties and hand values of polypropylene knit and to analyze its color-fastness for light, laundering and abrasion, comparing to nylon and polyester knits. The results of this study were as follows: 1. Polypropylene stretched more with less force than nylon and polyester and its elastic recovery and shape stability were better than nylon and polyester. 2. Polypropylene was more flexible than nylon and polyester. 3. Polypropylene stretched more easily for shearing but its recovery from shearing was less than nylon and polyester. 4. Polyester had smoother surface than nylon and polyester. 5. Polypropylene was compressed more easily than polyester with less force but less than nylon. Its recovery from compression was more than nylon and polyester. 6. Polypropylene had lower KOSHI and SHARI values and higher FUKURAMI value than nylon and polyester. It had better T.H.V. value than nylon but less than! polyester. 7. Color fastness of polypropylene for lanudering, light, and abrasion in wet and dry conditions was good except polypropylene dyed with red color.
