Stretchy materials refers to fabrics which can stretch without breaking the fibers and return to its original length. This stretch of the fibers provides clothes/accessories made with them the much needed ease, drape, comfort and fitting.
There are two types of stretch materials according to the way they stretch.
2 way stretch materials – These fabrics stretch in one direction either lengthwise or crosswise.
4 way stretch materials – These fabrics stretch in two directions – crosswise as well as lengthwise ie They can be stretched sideways as well as along the selvedges

Below are the materials I have seen which have some or lots of stretch. The elasticity of these fabrics are a result of the yarns of which they are made of. The most popular yarn is spandex , then there is a rubber core yarn, and there are specially made stretchy yarns made of polyester, nylon and natural fibers.
To ascertain the stretch you will have to go by the percentage of spandex/ elastane/stretchy yarn in the fabric or try it yourself to see whether the stretch of the fabric suits your purpose. For example some fabrics with a 4 way stretch will stretch more in one direction than the other
A good method is to take a 4 inch square piece of the fabric and stretch it; Keep it against a tape measure and see how it stretches out. You can compare the stretch against the percentage given.
The method to determine the stretchiness of a fabric
This is important to do before you make things with the fabric because the different fabric stretches differently.
Fold the fabric on the crosswise grain, some distance from the cut edge
Mark a 4-inch section on this fold
Keep a long ruler along the folded edge.
Keep one edge of the ruler at the start of the marking you have made.
Gently but firmly stretch this fabric.
see how much it stretches –
If it stretches less than 4 1/2 inches it is a stable not so stretchable fabric
If it stretched about 5 1/4 inches it has a moderate stretch
If it stretches more than 6 inches it is a true blue stretchable fabric

This synthetic fabric has revolutionized the textile industry with its ability to stretch to almost 300-400 percentage on its own. The stretchiness of spandex depends on its elastane content. 1-5% is common in comfort wear whereas sports wear usually has elastane content of about 12-15%.

Latex is made from the sap of the rubber tree. Rubber can be used to make clothes but mind you, not everyday clothes. It is very difficult to sew and very difficult to wear – no breathing and at times irritating to skin. But the stretch of rubber (more than even spandex) and water resistance makes it desirable for certain items. One precautionary note on fabrics made with rubber core yarns – do not dry clean. Dry cleaning fluid can damage the fabric.
