Where do rags come from? A major source is clothing. That’s bit more interesting. We are all interested in clothes more than rags, right? And what are clothes made of? Well, fabric of course. Let’s drill this down a bit more.
Broadly speaking there are natural fibers and synthetic fibers that are spun and woven into fabrics.
Some natural fibers have been in use for thousands of years, others are more recent. Silk comes from the cocoons of certain moth caterpillars and was first woven into fabric in China up to 6,000 years ago. Linen is made from the fibers of the flax plant and dates back to at least ancient Egypt. Canvas was originally made from hemp. Wool of course comes from sheep and other animals, while cotton comes from the cotton plant.
