First of all, the composition of the fabric can only partially determine whether the fabric is soft or firm. Because a lot of hand feel can also be reflected through the finishing of the fabric, such as adding silicone oil, which is often added in shampoo, the fabric will be very soft.
The hemp cotton you mentioned is not a kind of cotton, but a blend of cotton fiber and hemp fiber, that is, there are two kinds of fibers in the fabric. Generally, hemp clothes are relatively stiff, because hemp fibers can be understood as relatively not easy to bend, and will stick out in the clothes, like root thorns, which is why some hemp clothes are itchy. So in ancient times, common people wore hemp clothes, while nobles and rich people wore silk clothes
Combed cotton is just another combing process when producing cotton yarn. The fabric of combed cotton can be understood as a cotton fabric with better quality, but it is still cotton. Rayon is viscose fiber, a kind of regenerated cellulose fiber. It is made from cellulose in wood. Usually, the fabric is soft, and sometimes it is blended with cotton.
I don't know if the cotton you mentioned is Modal. Modal is also a kind of regenerated cellulose fiber, which is a little higher than rayon, and more expensive. The fabric is very soft, and it is generally used for underwear. Most casual T-shirts are pure cotton. Sports T-shirts are usually made of pure fiber or chemical fiber and cotton. T-shirts are usually soft and comfortable, so there are few hard ones. The hemp inside the fiber should be the hardest. If you want to cover meat, go to a clothing store. Different styles and fabrics may also achieve the effect you want.
