用功率谱法分析混纺纱混纺比的不匀

Analysis on Irregularity of Blend Ratio with Power Spectrum Estimation Method

本文采用功率谱法估计的方法分析了半熟条、熟条、粗纱、细纱混纺比沿须条轴向的周期性不匀,为方便有效地分析混纺比与工艺的关系奠定了基础.

The power spectrum estimation method is used to analyze periodic irregularity of blending ratio along the axis of the blended sliver, drawing sliver, roving and yarn, which is conveniend and efficient for analyzing the ralationship between blending radio and the technology.
