Testing method for unevenness of textile yarn evenness
Part 2. Optical methods
1 Scope
GB/T 3292 This section specifies the method for determining the diameter of the yarn unevenness of the photoelectric type yarn evenness tester along the longitudinal direction.
This section applies to a variety of fibers, yarns approximately circular cross-section.
Note. Detection principle Photoelectric Method and capacitance method is different, as reflected in the photovoltaic method yarn evenness refers to the approximate diameter of the circular projection of the yarn unevenness, and capacitance method
As reflected in the linear density unevenness correlated, but not identical.

3 Terms and Definitions
The following terms and definitions apply GB/T 3292 of this section.
3.1
Linear distance between two points in the longitudinal direction on the outer contour of the projection yarns formed perpendicular to the yarn.
3.2
