Everything is essentially biodegradable. Cotton with polyester blended in, or polyester alone will take longer to biodegrade than 100% cotton, for example.
They are usually made of fabric that is non-biodegradable, usually polyester, viscose or rayon.
Natural materials are by definition biodegradable. That means that cotton, wool, linen and silk fulfill this criterion. Cotton and linen are cellulose based (a polysaccharide) while wool and silk are made of protein types )wool is made of keratin as is human hair). Of the others only certain types of polyesters are biodegradable such as for example polylactic acid. What is commonly labeled as polyester in garments is not biodegradable.
No, cotton is a natural fibre made from the cotton plant, and polyester is a man-made synthetic fabric which is a petroleum-by-product.
It depends. If your sewing thread is 100% cotton, yes. If youre sewing thread is 100% or any% polyester, no. Cotton is a natural material where polyester is a man-made, synthetic material.

Most T-Shirts are made of Cotton, and since Cotton is a Natural Fabric, it is biodegradable. If a T-Shirt is a blend (containing more than one type of fabric), and one of the blended fabrics is NOT Natural, the T-Shirt would ONLY be partially biodegradable (the portions made up of the Natural fabrics). Nylon & Polyester are Fabrics which ARE NOT Natural; therefore NOT Biodegradable. Cotton & Hemp are Fabrics which ARE Natural; therefore they ARE Biodegradable.
Polyester clothing is made from a petroleum product called polyethylene terephthalate so it is somewhat flammable and will melt. There is an in-depth, but complicated, definition that basically explains it is made from fibers that are a chain of several linked esters, at whatispolyester.com.
Whatever caveman first whacked some hide off a dead animal to use as clothing. ========================================================= I would say the stick he whacked it with was the first biodegradable product. (weapon.)
Polyester is a man made material that is fabricated as a thread and then woven into a material. Leather is a natural product made by tanning animal skins.

Biodegradable is when some thing you own, eg, a carrot can rot or fade away and turn into the product they were made out of in the first place, like turning into dirt again. The item which is Biodegradable also doesn't pollute the earth because it is made out of natural resources.
Cloth is biodegradable and is readily broken down if it is made from natural materials (cotton, linen, flax, silk). This makes it an environmentally friendly material. Cloth made from plastics (polyester, nylon, etc) is not biodegradable, but, like plastic, takes hundreds of years to break down, and when it does, it is often just into tiny pieces of plastic the insects, animals and birds eat by mistake.
