Yarn characteristics

- Jul 31, 2017-

1. Bulk density: Reflect the characteristics of fiber stacking;

2. fiber twist angle, curl, etc.: reflect the fiber along the yarn axis of the degree of straightness;

3. The number of shares of the shares, twist to:

4. Line density (diameter) and coefficient of variation: Reflect the yarn thickness and change

5. The force between the fibers (friction factor, entanglement point, the role of the fragment or slip length, etc.): reflect the stability of the yarn structure
