Description

There is a problem that it can not be answered. In addition, polydimethylsiloxane, amino-modified silicone, and those comprising magnesium stearate having a specific particle size (see, for example, Patent Document 3), etc. have also been proposed. There is a problem that it is easy to cause the shape defect due to magnesium oxide, and it is impossible to obtain a synthetic fiber having both the processing grade and the shape.
