What are the criteria for judging the three-strand rope?

There are three indicators for judging whether the three strands are up to standard:

1, twist

When the three strands are twisted, the two sections produce the same number of revolutions, which is expressed by the number of turns in the unit length, which is called the twist.

2, the corner

The roundabout is used to measure the degree of twisting of different thick slivers. The busbar that has been twisted and becomes a cylindrical spiral is unfolded, and the pitch is L. The spiral is expanded in the pitch to be a right-angled triangle. The tangent to any point on the helix is at an angle β to the axis, called the meander angle.

3, banner

When twisted, the length of the arc that is rotated in a unit length by a point on the yarn section is called a web.
