Correct Answer: hemp
the question requires the identification of a type of natural fiber from a given list. the options provided include polyester, hemp, fiber glass, and polyamide nylon. to determine which among these is a natural fiber, it is essential to understand the nature and origin of each material listed.
polyester and polyamide nylon, commonly known as nylon, are both synthetic fibers. they are manufactured through chemical processes, typically involving petroleum as a base material. these fibers are known for their durability, elasticity, and resistance to environmental factors, making them popular in various applications ranging from clothing to automotive industries. however, since they are chemically synthesized, they do not qualify as natural fibers.
fiber glass, another option listed, is a type of fiber reinforced plastic where the reinforcement fiber is specifically glass fiber. this material is neither derived from plant nor animal sources but is made from various types of minerals combined with plastic resins. it is predominantly used for its strong insulating properties and strength, but like polyester and nylon, it is also synthetic.
hemp, on the other hand, is indeed a natural fiber. it is derived from the cannabis sativa plant, specifically from the stalk of the plant, which is processed to extract the fiber. hemp fiber is one of the oldest and most versatile natural fibers known. it has been used historically for making ropes, textiles, and paper. the recent resurgence in its popularity can be attributed to its environmental benefits, such as biodegradability and the minimal use of pesticides and fertilizers during cultivation. additionally, hemp is also utilized in producing biodegradable plastics, health food, and even as a biofuel.
therefore, among the options listed—polyester, hemp, fiber glass, and polyamide nylon—the correct answer to the question identifying a type of natural fiber is hemp. this is because it is the only option that is derived from a natural source and is not synthetically produced.
