摘要：
There is provided a method for splitting a split type conjugate fiber. The method includes four steps. Firstly, there is provided a first polymer with crystallization of 40% to 95% and a second polymer with crystallization of 1% to 25%. Secondly, a conjugate fiber is made of the first and second polymers by conjugate spinning. Thirdly, the conjugate fiber is submerged in water so that the conjugate fiber contains water. Finally, the conjugate fiber is heated and split into fine fibers.
