| Abstract: | The distribution of TiO2 particles as flatting agent in fine denier polyamide 6 monofilament was investigated via synchrotron radiation X-ray nano CT technique. 2D and 3D reconstructed images of the polyamide 6 monofilament with different contents of TiO2 particles were obtained by treating the projection images with filter back projection algorithm and digital image processing methods. As the content of TiO2 particles increases, the agglomeration of TiO2 particles becomes more severe. As a result, agglomerated TiO2 particles whose diameter is around 800 nm were observed in the full dull polyamide 6 monofilament. The agglomeration of TiO2 particles is relevant to the decrease of the spinning stability in the manufacturing of full dull fine denier polyamide 6 fibers. |
