1. A fiber analysis method for determining ratio of components in the fiber mixture comprising hydrophobic fiber component and thermoplastic fiber component, characterized in that it comprises the following steps;
a) putting of sufficient amount of fiber in the DSC device,
b) application of thermal cycle,
c) recording of liquid output peak area of the hygroscopic composition and/or melting peak area of thermoplastic fiber read from thermogram obtained from DSC as a result of thermal cycle,
d) recording of indium peak area read from thermogram obtained from DSC a result of thermal cycle, and
e) application of liquid output peak area and/or melting peak area with indium peak area to an equation formed to find the ratio of a hygroscopic composition and/or the ratio of thermoplastic fiber.
