    • PROBLEM TO BE SOLVED: To provide a fiber having 4T-shaped cross section, capable of being into a woven fabric having specifically excellent in water absorption and quick drying.SOLUTION: The fiber contains four T-shaped lobes, wherein each of the T-shaped lobes has a cap and a leg, and by connecting the legs of the respective T-shaped lobes to the center of the fiber at predetermined intervals, an opening-type hollow part is formed among the adjacent T-shaped lobes. The fiber satisfies the following numerical formulae (1)-(4): formula (1) 0.8≤ denier value ≤20; formula (2) 10°≤θ≤60°; formula (3) 10%≤ hollowness ≤30%; formula (4) 2≤ modified cross section degree (R/r) ≤6; wherein θ presents a width range of the opening in the hollow part; R represents a radius of the circumscribed circle against the fiber, and r represents a radius of the inscribed circle against the fiber.
    • 要解决的问题:提供一种具有4T形横截面的纤维,其能够成为具有特别优异的吸水性和快速干燥性的织物。溶液:该纤维包含四个T形裂片,其中每个T- 形状的叶片具有帽和腿,并且通过将各个T形瓣的腿以预定间隔连接到纤维的中心,在相邻的T形瓣中形成开口型中空部。 纤维满足下列数学式(1) - (4):式(1)0.8≤旦尼尔值≤20; 式(2)10°≤θ≤60°; 式(3)10%≤空心度≤30%; 公式(4)2≤修正截面度(R / r)≤6; 其中θ表示中空部分中的开口的宽度范围; R表示针对纤维的外接圆的半径,r表示针对纤维的内切圆的半径。
