the utility model discloses when realizing closely spinning:

(1) because the utility model discloses a mode that twists with the fingers earlier the fibre after the draft again twists with the fingers earlier, consequently improved the cohesion force between the fibre (cohesion force means that textile material is because the fibre is thin and soft to there is better elasticity, when the tangential resistance of normal pressure equals zero, fibre area of contact is big more, combines inseparabler, cohesion force just is big more), makes the powerful improvement 10% of yarn, and elongation at break improves 10%;
