Sea-island fiber is a polymer dispersed in another polymer. The dispersed phase in the cross-section of the fiber is in an “island” state, while the matrix is ​​equivalent to the “sea”. From the cross-section of the fiber, it is a component with tiny And the dispersed state is surrounded by another component, as if there are many islands in the sea �其“岛”与“海”成分在纤维的轴向上是连续、密集、均匀分布的� �在生产过程中,它具有常规纤维的纤度,但是用溶剂把“海”成分溶掉,则可得到集束状的超细纤维束� �</p

  根据纤维的一般分类,海岛纤维分离后,单丝纤度仅0.05D,属超细纤维,常规纺丝不可能做到,因此它具有一般纤维不可能有的特性。

a. High coverage: <br /
    随着纤维纤度的降低,直径变细,单位重量纤维的表面积增加。随着表面积的增加,纤维的覆盖能力增加,吸湿性能大大改善。
b. Soft to the touch and comfortable to wear:<br /
    由于纤维超细,纤维更加柔软,制成织物,可产生毛细管的芯吸作用,使织物吸附更多水分,并可将这些水分移至织物表面,使其蒸发,增加了穿着的舒适感。
c. The fabric has soft luster: <br /
    超细纤维的直径越小,纤维的曲率半径越大,其表面反射的散射光占的比例越大,使织物表面的色调比较柔和。

  通过织物的设计加工,利用海岛纤维极度的细纤化特点,可以获得许多特殊的织物风格,如仿羊绒、仿麂皮、超高密织物等。这类织物可广泛运用于服装、服饰领域、箱包、室内用品及产业领域等。

利用海岛纤维开发的仿麂皮绒织物的许多性能并不亚于天然麂皮,有许多性能甚至优于天然麂皮。其织物手感柔软,悬垂性好,质地轻薄,为真皮的一半,可织成不同厚度和重量的织物;可以进行种种表面处理,取得形形色色的表面效果。表面有书写效果,立体感好;湿热收缩变形小,具有良好的防水透气效果,织物强度高,远优于天然麂皮。
