Question

The typical shapes of comb sorter diagram and fibrogram of polyester fibres of equal cut length will be

• A. Triangular and rectangular respectively
• B. Rectangular and triangular respectively
• C. Rectangular and S-shaped respectively
• D. S-shaped and triangular respectively

Hint:

A rectangular comb sorter diagram and a triangular fibrogram are typical for polyester fibers of equal cut length.

Answer 1

The Correct Option is B

In the comb sorter diagram, the distribution of fiber lengths for polyester fibers is typically rectangular, meaning that the fibers are evenly distributed within a certain range of lengths. This suggests a uniform distribution where each fiber length has an equal probability of occurring. The fibrogram, which represents the frequency distribution of the fiber lengths, for polyester fibers of equal cut length typically has a triangular shape. This triangular distribution is indicative of the natural variation in fiber lengths, where most of the fibers are concentrated around a central value, and fewer fibers exist at the extremes of the length range. Thus, the correct shapes are rectangular for the comb sorter diagram and triangular for the fibrogram. Final Answer: \boxed{(B) Rectangular and triangular respectively}
