In an experiment I did with silicon carbide fibers, the thicker fibers (bigger diameter) had slightly higher frequencies (referring to the first natural frequency).

Soundproof cotton can be effective in reducing noise levels in a room by absorbing sound waves and reducing echoes. However, its effectiveness may vary depending on the thickness and quality of the material, as well as the frequency and intensity of the noise.
it helped speed up the cotton process and helped many people get jobs
Cotton fabric can vary in thickness depending on factors such as the type of weave and number of threads. Generally, cotton is considered to be a medium-weight fabric that is breathable and versatile for a variety of uses.
No, it is not stretchy. It is a woven cotton fabric.
Cotton is an inelastic product, meaning its quantity demanded does not change significantly with price fluctuations. This is because cotton is a basic necessity and its demand remains fairly stable regardless of price changes.
The cotton gin change the textile industry by making it possible for cotton to be processed at a faster rate. This helped to make clothing and other items made using cotton more popular and sought after. Once that happened employment and industry got a big boost.
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.
It decreased during the cotton gin :)
young people started to eat old ladies' hair thinking it's cotton candy ;-)
It is a chemical change, because when cotton is being woven into sheets, we cannot change sheets into cotton again, hence it is difficult to reverse.
calico is just basic cotton woven round its self again and again but it depends on the thickness. Different thicknesses makes different thickness of calico. Calico is unbleached so it is more enviromentally friendly!
