Humans have been using cotton to make fabric (织物) for clothing for over 7,000 years. The ancient Egyptians produced it. Today, people still use this kind of natural material most commonly in the world.
You might not pay attention to it, but in your everyday life, you use cotton everywhere. When you wake up in the morning, you sleep on bed sheets (床单) made of cotton. You take a shower and when you dry yourself, you probably use a towel made of cotton. You put on your clothes, which probably have at least some cotton in them.
Cotton has many advantages that make it an excellent clothing material. On hot days, cotton clothing feels cool. On cold days, cotton clothing keeps you warm.
Cotton fabric is made from the cotton plant, a small plant that’s easy to grow. The seeds (种子) of the cotton plant are surrounded by fluffy (绒毛般的) white fibers (纤维) for protection. These fibers are collected and made into cloth, which can then be made into many products.
The cotton seeds are not wasted, either. They are put in a machine that presses the oil out of them. This oil is a valuable product for cooking and is used in many kinds of food. The mush (碎屑) that’s left is used to feed animals, such as pigs and cows.
Nothing is wasted. That’s why cotton is a very useful plant. Even more importantly, cotton is a natural product. It doesn’t require a lot of energy to produce, and it can be renewed every year simply by planting a new crop.
