Outline of Final Research Achievements

Destruction of bobbins or warping beams occurs frequently in textile factory. The cause is considered to be over compressive stress for barrel and flanges　accompanied by winding high modulus yarn. This research tried to shows the effects of winding conditions, such as yarn tension, traverse motion, on the　compressive behavior of internal yarn layer. A high precision programmable model winder that can wind up any form of package was developed. The motion of the winder is controlled by machine automation controller and synchronized servo motors. As a primary step of X-Ray CT scanning of internal yarn layer, observation of internal yarn layer deformation is tried by high resolution digital camera. Affect of winding conditions on the strain of internal yarn layer is observed.
