What Is String Made Of?

String is most commonly made of cotton. Polyester, hemp, nylon and linen are also used to manufacture string. Strands of fibers are spun or twisted together to form string. The thickness of the string is determined by how many strands of fiber are spun together.

String has a wide variety of uses, such as craft projects and making kites. The tightness of the twist and the type of material used determine the strength of the string. However, in some applications, flexibility is more important than tightness. The durability of the string is also an important factor. String can become damaged from the sun. It can also become weakened when exposed to water.
