| | Acrylic synthetic fiber improved in styleability patent invention (Site not responding. Last check: 2007-11-07) |
 | | For example, conventional fibers are classified into synthetic fibers suitable for curly style, or synthetic fibers suitable for straight style, respectively, and since only a few synthetic fibers having wide stylability (fiber function enabling various styles for wigs) are marketed, development of such synthetic fibers are now demanded. |
 | | Although application of specific unevenness to a fiber surface is effective method for improvement in stylability, indeed, only application of simple surface unevenness cannot improve rigidity of the fiber, and, as a result, cannot sufficiently satisfy salability of straight style. |
 | | First, a fiber bundle is heat-treated under conditions of arbitrary temperature and unstrained for 30 minutes, and a sample length LD (mm) after cooling to a room temperature is measured. |
