According to Sadykova 1972, the Poisson ratio express the change in the volume of a solid undergoing deformation. For cotton it would be how the Cotton fiber volume will change when apply a tensile force in X direction and how much changes will happen in the lateral direction. That is Passion ratio, I did not find anyone how calculated that for cotton fibres but there are some studies for the woven fabrics or yarns. If I am not mistaken some Instron testers can calculate that for your sample directly.

What does zero Poisson's ratio mean?
For elastic, isotropic and homogeneous materials, zero Poisson's ratio means that the material doesn't present lateral deformation on bending, compressing or extending.
How do you find poision ratio of alluminium?
There are test standards to determine poisson ratio. For aluminum, it is 0.33
What does poisson mean?
"poisson" is a fish.
What is the difference between poisson distribution and poisson process?
A poisson process is a non-deterministic process where events occur continuously and independently of each other. An example of a poisson process is the radioactive decay of radionuclides. A poisson distribution is a discrete probability distribution that represents the probability of events (having a poisson process) occurring in a certain period of time.
If X has Poisson distribution does aX plus b have Poisson Distribution?
Yes.
