FIBER WITH MODIFIED CROSS SECTION AND FIBER FOR ARTIFICIAL HAIR FORMED OF THE SAME |
摘要 |
<p>A fiber with a modified cross section having excellent bulkiness, not fused, and manufacturable stably. In the fiber with the modified cross section, at least two hollow parts with openings that are open in the longitudinal axis of the fiber are formed in the cross section of the fiber. These two hollow parts are symmetrically formed with their backs facing each other, and the cross section of the fiber is formed in such a shape that generally C-shaped portions each curved arcuately are joined with their backs facing each other. The shape of each generally C-shaped portion desirably fulfills the requirement of the following expressions: 1.4R<SUB>2</SUB> = R<SUB>1</SUB> = 4.2R<SUB>2</SUB> and 10° = ? = 160° (in the expression, R<SUB>1 </SUB>is the maximum outer dimension passing through the center of a hollow part assumed inscribing circle, R<SUB>2</SUB> is the diameter of the hollow part assumed inscribing circle, and ? is the angle formed by the center of the hollow part assumed inscribing circle and the two ends of each generally C-shaped portion).</p> |
