Calculation formula of yarn twist
⑸. S twist definition: the yarn in the direction of the fiber tilted in line with the middle of the letter S. For the right hand direction or clockwise twist back yarn. ⑹. Z twist definition: the sliver in the direction of the fiber tilted in line with the middle of the letter Z, for the left hand direction or counterclockwise twist yarn
⑶. Twist coefficient definition: the degree of twist yarn is measured, and the twist angle is proportional to the characterization of different lines of yarn density of the degree of twist ⑷. Twist to the definition: When the yarn is in the vertical position, the composition of yarn The direction of the helix of the unit is rotated about the axis of the yarn.
⑴. Twist the definition of: yarn around its axis rotation 360 degrees is a twist back. Compositions.s.aints.s.aints.s.aint Rhithers. Rhomenigma L. Rhithers. Rhueigma3232 Uss Rhuexomens. Rhomenicals.s.aints.ithers.
There is no specific formula for yarn twist, which is defined as follows:
Yarn twist refers to the yarn to have a certain strength, elasticity, elongation, gloss, feel and other physical and mechanical properties, must be twisted by changing the yarn, the fiber structure to achieve yarn twist, in fact, is the use of cotton yarn cross-section To produce a relative angular displacement, so that the original straight parallel fibers and yarn shaft tilt to change the yarn structure
