Texturing Yarns Manufacturers

The proportional Texturing Yarns Manufacturers between the mechanical wave and the fundamental wave is used to judge the harmfulness of the defect, and misjudgment often occurs.5, 4, 2.5, 2, 1. The spectrum, uneven curve, DR% curve, length-variation curve, linear density spectrum, cutting defect classification Figures are shown in Figures 22-27 respectively. portant;

The length-variation curve of the problem package portant; The DR% curve of the problem package Figure 03 Conclusion Non-sinusoidal periodic defects due to the Fourier In the process of leaf decomposition, it will be decomposed into a series of superposition of sine waves, especially as the distance between defects increases,

the average amplitude of the main wave will be affected, which will bring adverse factors to the analysis of the spectrogram.' (that is, detail yarn) will be displayed. Due to the poor yarn guide stroke and incorrect positioning of the frame, the whisker has almost no margin on the front top roller, and some fibers in the whisker are not effectively controlled by the front top roller,

resulting in a small thickness during the drafting process Adjust the yarn guide stroke and the positioning of the cradle so that the whisker runs in the middle of the front top roller, re-test the yarn sliver, and the shape of each pattern returns to normal, confirming that the problem is caused by the poor control of the fiber operation in the drafting zone

The shelling of the front rubber roller will also cause similar problems, see Figures 31-33.5 Case analysis of sprinkling of package yarn When an enterprise is doing R39. In the above example, another spindle of the same model and the same variety was found to have damage to the lower apron. According to the calculation formula of the spectrogram, the regular mechanical wave wavelength caused by the abrasion of the apron under the yarn is 83mm×3. 2.33/1. As the surface yarn of the yarn is gradually unwound, the moisture regain rate of the yarn tends to be stable, so the graphics
